[ first embodiment ]
Fig. 1 is a schematic diagram of a mobile device according to a first embodiment of the invention. Fig. 2 is a block diagram of a mobile device according to a first embodiment of the invention. Referring to fig. 1 and fig. 2, in the present embodiment, the mobile device 1 includes a body 10, a display 140, an edge detector 130, a processor 110 and a storage device 120. The processor 110 and the storage device 120 are disposed inside the body 10. The display 140 is disposed on the body 10 to display information contents to a user. The edge detectors 130 may be disposed at left and right sides of the body 10, for example, the left side S1 and/or the right side S2. In other embodiments, the upper and/or lower sides S3, S4 of the body 10 may also be provided with edge detectors. The edge detector 130 may have a plurality of detectors distributed on both sides S1, S2 where the edge detector 130 is disposed, for example, may be distributed in an even manner. As shown in fig. 1, for the edge detector 130 having 6 first to sixth detectors 130(1) to 130(6), 3 detectors on each side, for example, 3 detectors 130(1) to 130(3), are disposed on the left side S1; the 3 detectors 130(4) to 130(6) are provided on the right side S2.
In the present embodiment, the mobile device 1 is an electronic device such as a smartphone, a tablet computer, and a smart wearable device. The invention is not limited to the type of application of the mobile device 1. That is, any electronic device that can be configured with an edge detector can be considered as the mobile device of the present embodiment.
The processor 110 is coupled to the edge detector 130, the storage device 120 and the display 140. The processing unit 110 is a hardware (e.g., a chipset, a processor, etc.) with computing capability, and is used for managing the overall operation of the mobile device 1. In the embodiment, the Processing Unit 110 is, for example, a Central Processing Unit (CPU) of a core or a multi-core, a microprocessor (Micro-Processor), or other Programmable Processing Unit (Programmable Processor), a Digital Signal Processor (DSP), a Programmable controller, an Application Specific Integrated Circuit (ASIC), a Programmable Logic Device (PLD), or the like.
The storage 120 may be any type of Hard Disk Drive (HDD) or nonvolatile memory storage (nonvolatile memory module/circuit unit). The storage device 120 may store data as directed by the processor 110. The storage device 120 may store data in advance before shipment. The data includes data (software or firmware) for managing the mobile device 1, data for accessing other electronic devices/mobile devices, application programs, data inputted by a user, or other types of data, but the invention is not limited thereto. In addition, the storage device 120 stores a database 121, which can store/record relevant information, authentication data or password of a specific user via the direction of the processor 110.
Edge detector (Edge Sensor)130 (e.g., one of detectors 130(1) - (130 (6)) is, for example, a pressure detector, a resistance detector, a photo detector, or an acoustic detector. The edge detector is used to detect a holding action, such as a squeezing action, performed by the user on the mobile device 1 (as further described in fig. 3). In addition, the edge detector may also be used to detect other actions, such as a touch action, a slide action, a click action, and the like. In the present embodiment, the edge detector belongs to the pressure detector, and is an equalizing bridge structure composed of piezoresistors, and is installed on two sides (e.g., two sides S1, S2) of the outer frame of the mobile device 1, which are easily pressed by the palm of the user. When a user presses the outer frame of the mobile device 1 to deform the mechanism (for example, when the user performs a squeezing operation on the mobile device 1), the edge detectors 130 installed on one or both sides of the mobile device are deformed under the influence of the deformation of the outer frame, so that the resistance of the piezoresistors changes to cause the bridge to be unbalanced, and the detection signals (detection data) output by the bridge circuit change. Because the deformation of the edge detector 130 is related to the detection data outputted by the bridge circuit, through the relationship, the processor 110 can process the detection data to obtain the squeezing modes of the squeezing action at different time points, which may include single or combined squeezing intensity values, squeezing areas, squeezing positions, and squeezing numbers, to form a mode, thereby providing further functional applications.
Fig. 3 is a schematic diagram of a squeezing operation according to a first embodiment of the present invention, taking squeezing strength as an example. Referring to fig. 3, the user presses both sides S1, S2 of the mobile device 1 with finger or hand applying forces F1, F2 to grasp/hold the mobile device 1. For example, in the orthogonal coordinate system (in fig. 3, the x-axis direction extending from the left side S1 to the right side S2, the y-axis direction extending from the lower side S4 to the upper side S3, and the z-axis direction extending from the rear of the mobile device to the front) provided in the mobile device 1, the direction of the force F1 is the positive x-direction, and the direction of the force F2 is the negative x-direction. At this time, in response to the deformation caused by the forces F1, F2, the edge detector 130 may detect the "squeezing action" and the Strength (Strength) of the forces F1, F2.
In the present embodiment, when the signal level (voltage level/voltage value) of the detection signal output from the edge detector 130 exceeds the squeezing threshold, the processor 110 determines that the mobile device 1 is applied with a squeezing motion and a squeezing event occurs. In contrast, in another embodiment, when the signal level (voltage level/voltage value) of the detection signal output from the edge detector 130 does not exceed the squeezing threshold, the processor 110 determines that the mobile device 1 is not applied with the squeezing action, and the squeezing event does not occur. The signal level (voltage level/voltage value) of the detection signal may represent the intensity of the pressing action/touch action (e.g., a pressing intensity value or a touch intensity value). In addition, the pressing strength values obtained by detecting the pressing action over time can form a pressing strength curve.
Referring back to fig. 2, a display 140 is coupled to the processor 110 and is used for displaying the desktop, the played content or other visual information of the operating system of the mobile device 1. In the embodiment, the Display 140 may be a Liquid Crystal Display (LCD), a Light-Emitting Diode (LED) Display, or a Field Emission Display (FED). The display 140 may also be a touch screen composed of a display panel of other types of displays and a touch panel such as a resistive (resistive), capacitive (capacitive) or optical (optical) touch panel, and can provide both display and touch operation functions, or other displays capable of providing display functions, but the invention is not limited thereto.
Fig. 4 is a flowchart of a user authentication method according to a first embodiment of the invention. Referring to fig. 4, in step S41, in response to determining that a specific event occurs, a squeezing action performed on the mobile device 1 is detected via the edge detector 130. Specifically, in the present embodiment, the specific event may include, but is not limited to, one or a combination of the following events (1) to (6).
Event (1): the mobile device 1 receives an Incoming Call (Incoming Call). For example, when the mobile device 1 receives a call made by another mobile device, the processor 110 determines that a specific event occurs.
Event (2): the mobile device 1 receives a camera shutter operation. For example, the mobile device 1 detects that a button corresponding to a camera shutter is triggered/pressed, and the processor 110 determines that the mobile device 1 is receiving a camera shutter operation.
Event (3): the mobile device 1 receives a notification. For example, an application installed on the mobile device 1 sends a notification to the user in response to the received message; or a function of the mobile device 1 itself or an installed application program issues a notification under a specific condition to remind the user, such as an alarm clock or the like. The notification may include one of a sound notification, an image notification, a text notification, or a combination thereof.
Event (4): a predetermined program of the mobile device 1 is executed. For example, a user may trigger a function of an application installed on the mobile device (e.g., a function corresponding to a "phone" application; a function corresponding to a "camera" application) via a click/press/touch or squeeze operation; or the functions of the mobile device itself (e.g., turning on/off the display, powering off, restarting, screen shots, camera shutters, volume control, settings of the mobile device operating system, etc.) are triggered via the above-described modes of operation.
Event (5): the mobile device 1 is performed an unlocking operation. For example, the mobile device 1 is triggered to perform an unlocking operation.
Event (6): the mobile device 1 transitions from a stationary state (e.g., being stationary for a period of time) to a held state. For example, the processor 110 may detect whether the gesture of the mobile device 1 is changed from the stationary state to the held state by a detector such as an accelerometer of the mobile device 1. When the processor 110 determines that the mobile device 1 is turned from the stationary state to the gripped state (or taken up from the stationary state), the processor 110 determines that a specific event occurs. The present invention is not limited to the manner in which the processor 110 determines that the mobile device 1 is changed from the stationary state to the held state, and different determination or detection may be performed for different manners.
In response to the occurrence of the specific event, the processor 110 instructs the edge detector 130 to start detecting the squeezing action applied/executed on the mobile device 1, so as to execute an authentication procedure according to the detected squeezing action to obtain a user authentication result, thereby checking whether the user currently holding the mobile device 1 is the specific user.
Next, in step S43, the processor 110 reads the verification data corresponding to the specific event from the database 121.
In particular, database 121 may store verification data corresponding to a plurality of different specific events.
Fig. 5 is a schematic diagram of a plurality of verification data corresponding to different specific events according to the first embodiment of the invention. Referring to fig. 5, in the present embodiment, the verification data 500 may include a plurality of predetermined maximum extrusion strength value ranges and a plurality of predetermined extrusion characteristic value ranges respectively corresponding to a plurality of specific events (e.g., events A, B-Z). For example, the verification data 500 may record the predetermined maximum squeezing strength value ranges MSSL _ a to MSSH _ a and the predetermined squeezing feature value ranges MSCL _ a to MSCH _ a corresponding to the event a, where MSSH _ A, MSSL _ a is a squeezing strength value greater than zero and respectively represents upper and lower boundaries of the predetermined maximum squeezing strength value range corresponding to the event a, and MSCH _ A, MSCL _ a is a squeezing feature value greater than zero and respectively represents upper and lower boundaries of the predetermined squeezing feature value range corresponding to the event a.
In more detail, the processor 110 may obtain a plurality of maximum squeezing strength values of a plurality of squeezing actions respectively corresponding to a specific event by receiving a squeezing action corresponding to the specific event performed by a specific user. Next, the processor 110 calculates a predetermined maximum squeezing strength value range according to a predetermined percentage and the maximum squeezing strength values. In one embodiment, the predetermined percentage may be determined by a statistical method. For example, assuming that the predetermined percentage is 10% and the maximum crush strength value is 100 units, the calculated predetermined maximum crush strength range is 90 (i.e., 100+100 × 10%) to 110 (i.e., 100+100 × 10%) units. In another embodiment, the processor 110 may continuously collect the maximum squeezing strength values of the squeezing actions of the specific user at the occurrence of the specific event for a period of time (e.g. one week) in daily life, and estimate the preset maximum squeezing strength range according to a plurality of maximum squeezing strength values collected at different times, so that the estimated preset maximum squeezing strength range may include all the maximum squeezing strength values corresponding to the same specific event as possible.
Next, in step S45, the processor 110 determines whether the user authentication result is successful or failed by comparing the authentication data with the pattern of the squeezing action. Specifically, the processor 110 may obtain the intensity of the squeezing action (i.e., the squeezing strength value) according to the squeezing action detected by the edge detector 130, and verify whether the user holding the mobile device 1 is the specific user when the current specific event occurs by comparing the obtained squeezing strength value with the verification data. That is, the processor 110 executes the authentication program according to the squeeze action to determine whether the user authentication result of the corresponding authentication program is successful or failed.
In more detail, in response to a pinching motion being detected, the edge detector may continuously output a pinching intensity value to the processor 110 over time. Within a first predetermined time after the squeezing action is detected, the processor 110 records a plurality of squeezing strength values of the squeezing action over time to obtain a squeezing strength curve corresponding to the squeezing action, wherein the squeezing strength curve represents the plurality of squeezing strength values of the squeezing action detected sequentially at different times within the first predetermined time.
Then, the processor 110 may identify a maximum crush strength value among the crush strength values according to the crush strength curve. For example, in the present embodiment, the processor 110 may identify the earliest ascending region in the squeezing strength curve (the ascending region reflects the initial output of the squeezing action). All crush strength values in the ascending region of the crush strength curve are greater than an initial threshold (e.g., 0 or the crush threshold described above). Then, the processor 110 may identify the largest of all the crush strength values of the ascending region as the maximum crush strength value. In short, after determining the ascending region of the crush strength curve, the processor 110 can start to search for the maximum crush strength value.
After identifying the maximum squeezing strength value, the processor 110 may compare the identified maximum squeezing strength value with a preset maximum squeezing strength range in the verification data to determine whether the maximum squeezing strength value is within the preset squeezing strength range. In response to determining that the maximum crush strength value is within the preset maximum crush strength range, the processor 110 determines that the user authentication result is successful. Next, in step S47, the processor 110 performs a first operation. In other words, when the user authentication result is determined to be successful, the processor 110 may determine that the user currently holding the mobile device 1 is consistent with a specific user, and correspondingly allow the first operation corresponding to the specific event to be performed.
In this embodiment, the first operation basically corresponds to a specific event. For example, the operation of performing the first operation includes, but is not limited to, one or a combination of the following: (1) unlocking the mobile device; (2) taking a photo or a movie, namely executing the function which is required to be executed after the shutter of the camera is triggered; (3) turning on a display/display screen of the mobile device; (4) responding to the incoming call corresponding to the specific event; (5) displaying a notification corresponding to the specific event; (6) executing a predetermined program corresponding to the specific event; and (7) performing a function of the mobile device corresponding to the specific event.
Otherwise, in response to determining that the maximum squeezing strength value is not within the preset squeezing strength range, the processor 110 determines that the user verification result is a failure. Then, the processor 110 performs a second operation.
In this embodiment, when the user authentication result is determined to be a failure, the process proceeds to step S49, and the processor 110 performs a second operation. In one embodiment, the second operation includes locking the mobile device 1. That is, when the user authentication result is determined to be a failure, the processor 110 determines that the current holding of the mobile device 1 is not a specific user, and takes security measures accordingly. The security measures may include, for example, locking the mobile device, powering off the mobile device 1, prohibiting the mobile device from performing any operations for a period of time, continuously turning off the screen of the mobile device, and not allowing the mobile device to perform any operations or other suitable security measures corresponding to an unauthorized user, but the invention is not limited thereto. It should be noted that, in another embodiment, the second operation further includes displaying a password input interface. The user can input a password for unlocking the mobile device through the password input interface.
In yet another embodiment, the second operation may include sending an alert notification to a registered user of the mobile device. The registered user may be a particular user of the mobile device or other registered user that may receive alert notifications. The alert notification is, for example, a notification transmitted by short message, telephone, instant messaging or email in the background, which indicates that the mobile device 1 is suspected to be held by a user other than the specific user. In addition, the alert notification may also include location information of the mobile device 1, such as information obtained via a GPS device or a communication device of the mobile device 1 to indicate the location of the mobile device 1, contact information, and the like. In an embodiment, the mobile device may take security measures and send an alert notification as the second operation at the same time.
In yet another embodiment, when the user authentication result is determined to be a failure, the processor 110 still performs the first operation and performs the second operation after performing the first operation.
It should be noted that, in another embodiment, in response to determining that the maximum squeezing strength value is not within the preset squeezing strength range, the processor 110 does not directly determine that the user verification result is a failure, and further performs another step to determine whether the user verification result is a success or a failure. Specifically, in response to determining that the identified maximum squeezing strength value is not within the preset squeezing feature range, the processor 110 does not first perform the second operation, but the processor 110 further reads the preset squeezing feature range corresponding to the specific event in the verification data 700 from the database 121 according to the specific event occurring currently, so as to attempt to compare the squeezing feature of the detected squeezing action with the preset squeezing feature range.
In more detail, in this embodiment, in response to the maximum squeezing strength value not being within the preset squeezing strength range, the processor 110 may calculate a squeezing feature quantity according to the identified maximum squeezing strength value and compare the squeezing feature quantity with the preset squeezing feature quantity range. In this embodiment, the processor 110 may integrate the pressing strength value with time according to the pressing strength curve located in the ascending region to obtain an integrated value, and take the integrated value as the pressing characteristic amount. In brief, the processor 110 calculates an area of the compression strength curve located in the ascending region to an abscissa axis (assuming that the compression strength curve is plotted in a graph in which an abscissa is time and an ordinate is a compression strength value), but the present invention is not limited thereto. The processor 110 may utilize other means to calculate the extrusion characteristic quantity from the maximum extrusion strength value or the rise region via other means. For example, in another embodiment, the processor 110 performs a root mean square operation on all the extrusion strength values in the ascending region according to the extrusion strength curve located in the ascending region, and uses the obtained result as the extrusion characteristic quantity. It should be noted that the preset squeezing feature range is set (or obtained) in a manner similar to the preset squeezing strength range (e.g., receiving a specific event corresponding to a specific user to perform a squeezing action on a mobile device or recording the squeezing action performed by the specific user when the specific event occurs in daily life to record a squeezing strength curve, and then obtaining a squeezing feature according to the squeezing strength curve), except that the step of "calculating/obtaining/recording the maximum squeezing strength value of the squeezing action corresponding to the specific event by the specific user" is changed to "calculating/obtaining/recording the squeezing feature of the squeezing action corresponding to the specific event by the specific user". The following description is given by way of example with reference to fig. 6A and 6B.
Then, in response to the calculated squeezing feature amount being within the preset squeezing feature amount range, the processor 110 determines that the user authentication result is successful without determining that the user authentication result is failed. Otherwise, in response to the calculated squeezing feature quantity not being within the preset squeezing feature quantity range, the processor 110 determines that the user authentication result is a failure. Next, the processor 110 performs the first operation or the second operation corresponding to the successful or failed user authentication result, as described above.
Fig. 6A is a plurality of graphs of the pressing strength respectively corresponding to a plurality of edge detectors according to the first embodiment of the invention. Referring to fig. 6A, in the present embodiment, the verification data corresponding to a specific event may also include a plurality of preset squeeze strength curves corresponding to different edge detectors 130(1) -130 (6). It is assumed that a plurality of pressing strength curve graphs corresponding to the first to sixth detectors 130(1) to 130(6) are shown in fig. 6A, wherein the preset pressing strength curves corresponding to the verification data of the first to sixth detectors are thicker curves. It is assumed that a plurality of squeeze intensity curves corresponding to squeeze operations detected by the first to sixth detectors 130(1) to 130(6) of the respective detectors of the specific event occurred at present are recorded as thin curves in the above-described squeeze intensity curve diagram. For a detector, the processor 110 may compare the preset pressing strength curve in the pressing strength curve corresponding to the detector with the pressing strength curve corresponding to the detected pressing action, so as to execute the verification procedure by the pressing action detected by the detector. In other words, it can be considered that corresponding verification procedures are respectively performed on the plurality of detectors to obtain a detector verification result of each detector.
FIG. 6B is a graph illustrating the pressing strength according to the pressing action detected by an edge detector according to the first embodiment of the present invention. Referring to fig. 6B (e.g., the pressing strength curve diagram of the third detector), for example, referring to the pressing strength curve (thicker curve) corresponding to the specific event, the mobile device 1 is determined to be in the stationary state (e.g., time T0-T1) at first, then, the processor 110 determines that the specific event occurs (e.g., is picked up from the stationary state), the user performs a pressing action on the mobile device 1 to pick up the mobile device, and during this period (e.g., time T1-T2) (i.e., during the pressing action), the pressing strength curve starts to rise (i.e., a rising region). During the pressing action, the processor 110 may determine that the highest point of the pressing strength curve in the pressing action is the maximum pressing strength value (e.g., 400). In addition, during the pressing action, the processor 110 may determine that the maximum pressing strength value (e.g., 800) is located at the highest point of the predetermined pressing strength curve (thinner curve) in the pressing action, and the corresponding predetermined pressing strength range is 720-880. Note that the period from time T2 to time T3 is, for example, a period in which the mobile device 1 is held.
According to the verification procedure, the maximum squeezing strength value is not within the preset squeezing strength range according to the squeezing action detected by the third detector. Based on this, the processor 110 may directly determine that the verification result corresponding to the third detector (i.e., the third detector verification result) is a failure. Alternatively, the processor 110, as described above, calculates the extrusion characteristic (e.g., calculates the area of the extrusion intensity curve in the ascending region and the abscissa axis), and performs further verification by comparing with the predetermined extrusion characteristic range.
It should be noted that the processor 110 may perform the verification procedure on the pressing intensity curve of the pressing action detected by each detector to obtain the verification result corresponding to each single detector. In this embodiment, in the case of multiple detectors, when the verification results corresponding to all the detectors are successful, or the verification results corresponding to a certain proportion or more than a certain number of detectors are successful, the processor 110 will determine that the user verification result is successful, thereby indicating that the user currently performing the squeeze operation is the specific user. For example, in one embodiment, when the number of detectors with successful verification results is greater than a predetermined threshold, the processor performs a first operation; otherwise, when the number of the detectors with successful verification results is not greater than the preset threshold value, the processor executes a second operation. The predetermined threshold may be predetermined by the system or may be user settable, and may be less than or equal to the number of all detectors.
Other verification procedures using the crush strength curve are described below with respect to a second embodiment. The corresponding component numbers and functions of the hardware of the second embodiment are the same as those of the hardware of the first embodiment, and are not described herein again.
[ second embodiment ]
Compared with the first embodiment, in the second embodiment, for a specific event, the processor 110 converts the analog squeezing strength value (squeezing strength curve) detected by each detector into a digital squeezing strength code in the detected squeezing action, and compares the digital squeezing strength code with the password corresponding to the specific event by using a plurality of squeezing strength codes respectively corresponding to a plurality of detectors to obtain a user authentication result, thereby determining whether the user is a specific user.
Fig. 7 is a flowchart of a verification method according to a second embodiment of the invention. Referring to fig. 7, in step S71, when it is determined that a specific event occurs, the processor 110 detects a pressing action applied to the mobile device through a plurality of edge detectors of the device to obtain a plurality of pressing strength curves respectively corresponding to the edge detectors (e.g., a plurality of pressing strength curves respectively corresponding to the first to sixth detectors as shown in fig. 6A).
In step S72, a plurality of compression strength codes respectively corresponding to the plurality of edge detectors are obtained according to the predetermined period corresponding to the specific event and the plurality of compression strength curves. The details of converting the squeeze intensity value into a squeeze intensity code are described below with reference to fig. 8A.
Fig. 8A is a diagram illustrating a conversion of a compression strength value into a compression strength code according to a second embodiment of the invention. Referring to fig. 8A, for example, assume that the left side of fig. 8A is a squeeze intensity curve according to a squeeze detected by a detector, which is formed by simulated squeeze intensity values detected at different time points. In the conversion process, the processor 110 divides the plurality of first extrusion strength values into a plurality of intervals according to the detected extrusion strength curve, also called the first extrusion strength curve, and the recorded extrusion strength values, also called the first extrusion strength values. The total number of the intervals may be set according to the safety intensity of the verification procedure, for example, the total number of the intervals may be increased if the safety intensity is required to be higher, and the plurality of intervals each have a corresponding compression intensity code.
For example, as shown in fig. 8A, the processor 110 divides the compression strength curve into three sections, such as a first section and a third section, according to the longitudinal distribution area of the compression strength curve. The first interval has an extrusion intensity code of "2"; the second interval has an extrusion intensity code of "1"; the third section has a squeezing pressure code of "0". That is, the processor 110 converts the extrusion strength values of the extrusion strength curves in different intervals into the extrusion strength codes of the intervals in which the extrusion strength values are located, as shown by the arrow a81, to obtain the extrusion strength codes at different time points, i.e., the first extrusion strength code, and further obtain the digital extrusion strength code map, as shown in the right side of fig. 8A.
For example, at time T0-T1, the squeezing strength curve is in the first interval, and the squeezing strength value in this interval is converted into a squeezing strength code "2"; at time T1-T2, i.e., the predetermined period, the compression strength curve is in the second interval, the compression strength value in this interval is converted into the compression strength code "1"; at time T2-T3, the squeezing strength curve is in the third interval, and the squeezing strength value in this interval is converted into the squeezing strength code "0". The predetermined period is a period of time, for example, 2 seconds, after the occurrence of the specific event is determined. It should be noted that the present invention does not limit the length of the predetermined period.
Fig. 8B is a diagram illustrating a plurality of compression strength codes respectively corresponding to a plurality of edge detectors after conversion according to a second embodiment of the invention. For example, referring to fig. 8B, after the compression strength curves corresponding to all the detectors are converted, a plurality of compression strength code maps respectively corresponding to the plurality of detectors can be obtained, as shown in fig. 8B.
Then, the processor 110 identifies a second compression strength code within the predetermined period and uses the second compression strength code as the compression strength code corresponding to the first edge detector. For example, in the compression strength code maps corresponding to the first to sixth detectors, the second compression strength codes in the predetermined period are "0", "2", "0", "1", "2", respectively. That is, the plurality of extrusion pressure codes obtained by the processor 110 respectively corresponding to the first to sixth detectors are "0, 2, 0, 1, 2".
After obtaining the plurality of squeezing strength codes respectively corresponding to the plurality of detectors, the processor 110 reads a password corresponding to the specific event from the database 121 in step S73.
Fig. 9 is a diagram illustrating a plurality of passwords corresponding to different specific events according to a second embodiment of the invention. Referring to fig. 9, the database 121 may store a plurality of passwords corresponding to a plurality of specific events, each password recording a plurality of code words (Unicode) corresponding to different detectors. For example, in the present embodiment, the password corresponding to the event a records codewords PW _ a1, PW _ a2, PW _ A3, PW _ a4, PW _ a5, and PW _ a6 corresponding to the first to sixth detectors, respectively; the ciphers corresponding to the event B record codewords PW _ B1, PW _ B2, PW _ B3, PW _ B4, PW _ B5, and PW _ B6 … corresponding to the first to sixth detectors, respectively, and the ciphers corresponding to the event Z record codewords PW _ Z1, PW _ Z2, PW _ Z3, PW _ Z4, PW _ Z5, and PW _ Z6 corresponding to the first to sixth detectors, respectively. For convenience of description, it is assumed that the specific event is event a, and the password read by the processor 110 is "PW _ a1, PW _ a2, PW _ A3, PW _ a4, PW _ a5, and PW _ a 6".
Next, in step S74, the processor 110 determines whether the user verification result is successful or failed by comparing the password with the plurality of squeezing strength codes.
Specifically, the processor 110 recognizes a plurality of codewords in the password respectively corresponding to the plurality of edge detectors. Further, the processor 110 also obtains the extrusion pressure codes respectively corresponding to the plurality of detectors in step S72. That is, the plurality of code words may correspond to the plurality of extrusion strength codes, respectively, by association with a plurality of detectors. Next, the processor 110 may determine whether the plurality of extrusion pressure codes conform to the corresponding plurality of codewords based on the plurality of detectors.
In this embodiment, in response to the squeezing strength codes of more than or equal to a predetermined number of detectors being determined not to correspond to the corresponding code words, the user authentication result is determined to be a failure. In response to fewer than a predetermined number of the crush strength codes of the detector being determined to not correspond to the corresponding code word, the user authentication result is determined to be successful. The predetermined number is set to, for example, a difference obtained by subtracting a predetermined threshold from the total number of all the detectors.
For example, assume that the predetermined number is 2, and the numerical values of the passwords "PW _ a1, PW _ a2, PW _ A3, PW _ a4, PW _ a5, PW _ a 6" read by the processor 110 are "0, 2, 0, 1", respectively, and the processor 110 compares them with the obtained plurality of squeezing intensity codes "0, 2, 0, 1, 2", respectively. In this example, the processor 110 determines that only the compression strength codeword "2" corresponding to the sixth detector does not correspond to the codeword PW _ A6, i.e., that only one compression strength code is determined not to correspond to the codeword. That is, less than the predetermined number 2 of crush strength codes are determined to not correspond to the corresponding code word. In this case, the processor 110 determines that the user authentication result is successful. Then, in response to the user authentication result being successful, proceeding to step S75, the processor 110 performs a first operation.
For another example, assume that the predetermined number is 2, and the numerical values of the passwords "PW _ a1, PW _ a2, PW _ A3, PW _ a4, PW _ a5, PW _ a 6" read by the processor 110 are "0, 2, 0, 1", respectively, and the processor 110 compares them with the obtained plurality of squeezing strength codes "0, 2, 0, 1, 2", respectively. In this example, the processor 110 determines that the compression strength codeword "1" corresponding to the fifth detector does not correspond to the codeword PW _ A5 "0" and the compression strength codeword "2" corresponding to the sixth detector does not correspond to the codeword PW _ A6 "1", i.e., the two compression strength codes are determined not to correspond to the corresponding codewords, indicating that up to a predetermined number 2 of compression strength codes are determined not to correspond to the corresponding codewords. In this case, the processor 110 determines that the user authentication result is a failure. Then, in response to the user authentication result being a failure, proceeding to step S77, the processor 110 performs a second operation.
In an embodiment, the predetermined number may be set according to a security strength. A lower security strength will use a higher predetermined number. In another embodiment, a predetermined number of matches may be determined, and the user authentication result is determined to be successful only if the predetermined number of matches is reached, otherwise the user authentication result is determined to be unsuccessful.
In summary, the user authentication method and the mobile device provided in the above embodiments of the invention can detect the squeezing action performed on the mobile device through the edge detector in response to determining that the specific event occurs, and compare the squeezing strength value or the squeezing feature quantity of the squeezing action with the authentication data to determine whether the user authentication result is successful or failed. In addition, a plurality of squeezing strength codes respectively corresponding to a plurality of edge detectors can be obtained from the detected squeezing actions, so as to judge whether the user verification result is successful or failed by comparing the password corresponding to the event with the plurality of squeezing strength codes. Finally, whether a first operation corresponding to a specific event or a second operation can be performed is determined according to the user authentication result.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
