detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

Embodiments of the present invention provide an information acquisition method, device and terminal. The details will be described respectively below.

Embodiment one,

This embodiment will be described from the perspective of an information acquisition device. Specifically, the information acquisition device may be integrated into a terminal, and the terminal may be a device such as a smart phone or a tablet computer.

An information acquisition method, comprising: when a terminal is in a working state, acquiring first fingerprint information of a user; verifying the first fingerprint information; if the verification fails, turning on a camera to collect image information of the user; saving the first fingerprint information and image information.

As shown in Figure 1, the information acquisition method, the specific process may be as follows:

101. Acquire first fingerprint information of a user when the terminal is in a working state.

Specifically, the working state refers to a non-screen-locked state. At this time, the terminal has unlocked the screen and entered the operation interface. A fingerprint recognition module can be set in the terminal, and when a fingerprint input operation is detected, it can be triggered to acquire the fingerprint information recognized by the fingerprint recognition module.

In this embodiment, in order to monitor unauthorized use of the owner's equipment by unauthorized users, relevant information such as fingerprints can be obtained without the operator noticing. There are many ways to obtain the first fingerprint information. For example, the operator will inevitably use the home button to perform operations such as returning to the home screen, returning to the previous page, and viewing the background when using the terminal. The operator triggers these operation instructions and collects the user's fingerprint at the same time to avoid the operator's detection; that is, the specific process of the step "obtaining the user's first fingerprint information" can be as follows:

Obtain the operation instruction triggered by the user through the fingerprint key;

Judging whether the operation instruction satisfies the preset condition;

If it is satisfied, the first fingerprint information of the user is obtained through the fingerprint key.

Specifically, a fingerprint key refers to a physical key or a virtual key with a fingerprint recognition module (such as a fingerprint sensor). The virtual key in the screen can also be a physical key located outside the display screen. The preset condition can be set by a person skilled in the art or by an equipment manufacturer according to characteristics such as the structure and function of the terminal. For example, the preset condition can be set as: instructing the interface to jump or switch; that is, the step of "judging whether the operation instruction satisfies the preset condition" can specifically be:

judging whether the operation instruction is an operation instruction of a preset type;

If yes, it is determined that the operation instruction satisfies the preset condition;

If not, it is determined that the operation instruction does not meet the preset condition.

In the specific implementation process, the preset type of operation instruction can be set as an interface switching instruction triggered by pressing or touching a fingerprint key, such as returning to the main interface, returning to the previous page, and so on. No matter what the judgment result is, the terminal can normally execute the operation instruction triggered by the user through the fingerprint key without being affected by the judgment result.

102. Verify the first fingerprint information.

Specifically, it can be determined whether the operator is an unauthorized user through fingerprint verification. Among them, there are many ways to verify the fingerprint information. For example, the fingerprint information input by the operator can be compared with the preset fingerprint information database; that is, the step "verifying the first fingerprint information" can specifically include :

judging whether there is sample fingerprint information matching the first fingerprint information in the sample set;

If it exists, it is determined that the verification of the first fingerprint information is successful;

If not, it is determined that the verification of the first fingerprint information fails.

Wherein, the sample set includes at least one sample fingerprint information. If it is determined that the verification is successful, it can be determined that the operator is an authorized user, and if the verification fails, it can be determined that the operator is an unauthorized user to a certain extent.

In the specific implementation process, in order to ensure the user experience and to prevent the operator from being aware of the monitoring operation of the terminal, no matter what the verification result is, the terminal can normally execute the above-mentioned operation command triggered by the user through the fingerprint key without being affected by the verification result. influences.

103. If the verification fails, turn on the camera to collect image information of the user.

Specifically, if the verification fails, it can be considered that an unauthorized user is using the owner's device privately. At this time, the camera can be turned on to collect the image information of the operator to record the current operator information. Wherein, the camera may preferably be a front camera, and of course, a rear camera may also be turned on. The collected image information may specifically be human body information, such as face information, body information, clothing information, and the like.

In the specific implementation process, it may be due to interference from external factors (such as water droplets), insufficient sensitivity of the fingerprint recognition module, etc., which may cause the fingerprint recognition module to obtain incomplete fingerprint information of the operator, resulting in fingerprint verification failure, making the terminal judgment. In order to avoid this misjudgment, the fingerprint information can be verified multiple times. If the verification fails for many times, it can be considered that an unauthorized user is using the owner's device privately. That is, after failing to verify the first fingerprint information and before turning on the camera, the method may further include:

Obtain the cumulative number of failed verifications of the current fingerprint information;

Judging whether the cumulative number of times is greater than a preset threshold;

If it is larger, perform the step of turning on the camera.

Wherein, the preset threshold can be set by a person skilled in the art or a device manufacturer based on the hardware structure and performance of the device, and of course, can also be set by the user according to the installation of software in the terminal. For example, the preset threshold can be set to 2 times, 3 times and so on.

104. Save the first fingerprint information and image information.

Specifically, after the verification of the first fingerprint information fails, the obtained first fingerprint information and the image information of the operator are stored in the storage area of the terminal for later viewing by authorized users. When the authorized user uses the terminal next time, he can go to the designated folder, read the security report, and check whether any unauthorized user has invaded the mobile phone. If there is any abnormality, he can check the photo and fingerprint to determine the information of the unauthorized user.

In this embodiment, there is no time sequence requirement for the operation of saving the first fingerprint information and the operation of turning on the camera. That is, step 103 may be performed after saving the first fingerprint information and before saving the image information, or after verifying the first fingerprint information and before saving the first fingerprint information.

In specific implementation, after the verification of the first fingerprint information fails, the current operator's operation records can also be recorded, such as which files have been checked, which files have been sent, copied, etc., and are stored in the security report.

In practical applications, in order to avoid misjudgment by the terminal due to interference from external factors, insufficient sensitivity of the fingerprint recognition module, etc., resulting in wrongly acquired and wrongly saved fingerprint information and image information, occupying unnecessary storage space, the wrongly saved information can be deleted ; That is, after saving the first fingerprint information and the image information, the method may also include:

judging whether the second fingerprint information is acquired within a preset time period;

If so, verifying the second fingerprint information;

If the verification is successful, the stored first fingerprint information and image information are deleted.

Wherein, the preset time period may be set by a person skilled in the art or a manufacturer, for example, the preset time period may be set as 10s, 1min and so on.

Specifically, considering that terminal models are generally fingerprint recognition and home button multiplexing models, the operator will constantly use the function of the home button in the process of using the terminal. Therefore, as long as the preset time period is set reasonably, it can be considered that the fingerprint information obtained within the preset time period, that is, the fingerprint information input by the same operator through the fingerprint key (ie home key), and the fingerprint information authenticating. If the verification is successful, it is considered that the previous verification failure is a misjudgment by the terminal. At this time, the stored first fingerprint information and image information may be deleted to expand the storage space.

As can be seen from the above, the embodiment of the present invention provides a method for obtaining information. When the terminal is in the working state, the first fingerprint information of the user is obtained, and then the first fingerprint information is verified. If the verification fails, the camera is turned on. To collect the user's image information, and finally, save the first fingerprint information and image information; this scheme can collect and save the current operator's fingerprint information and image information when the fingerprint verification fails, and compared with the existing technology, it improves the terminal security of information.

Embodiment two,

According to the method described in Embodiment 1, an example will be given below for further detailed description.

In this embodiment, it will be described in detail by taking the information acquisition device integrated in the mobile terminal, multiplexing the fingerprint key and the home key (home key), and integrating it into the mobile terminal in the form of a physical key as an example.

As shown in Figure 2, a method for obtaining information, the specific process may be as follows:

201. The mobile terminal acquires authentication information input by a user, where the authentication information is used to unlock a screen.

In this embodiment, the mobile terminal needs to enable the screen lock, and the screen lock can only be entered into the operation interface after successful unlocking. Specifically, the authentication information may be gesture information (such as a pattern password), biometric information (such as a fingerprint password), text information (such as a digital password), etc., and is used to unlock the screen.

202. The mobile terminal judges whether the authentication information is the same as the preset authentication information; if yes, execute step 203; if not, execute step 205.

Specifically, after acquiring the authentication information input by the user, the mobile terminal may call the preset authentication information stored in the database, verify the acquired authentication information based on the preset authentication information, and judge whether the authentication is successful.

203. The mobile terminal releases the screen lock, and acquires the fingerprint information of the user by pressing the home key.

Specifically, when it is determined that the authentication information is the same as the preset authentication information, that is, the obtained authentication information is verified successfully, at this time, a related program may be invoked to release the screen lock, so that the mobile terminal enters the working state. Wherein, the home key is a physical key with a fingerprint identification module (such as a fingerprint sensor). When a fingerprint input operation is detected, it can be triggered to acquire the fingerprint information identified by the fingerprint identification module.

In this embodiment, in order to monitor unauthorized use of the owner's equipment by unauthorized users, information such as fingerprints can be obtained without the operator noticing. There are many ways to obtain fingerprint information. For example, when using a mobile terminal, the operator will inevitably use the home button to perform operations such as returning to the home screen, returning to the previous page, and viewing the background. In view of this, you can The operator triggers these operation instructions and collects the user's fingerprint at the same time to avoid the operator's detection; that is, the specific process of the step "obtaining the user's fingerprint information by pressing the home button" can be as follows:

Obtain the operation command triggered by the user through the home button;

Judging whether the operation instruction satisfies the preset condition;

If it is satisfied, the fingerprint information of the user is obtained through the fingerprint key.

For example, the preset condition can be set as: instructing the interface to jump or switch; that is, the step of "judging whether the operation instruction satisfies the preset condition" can specifically be:

judging whether the operation instruction is an operation instruction of a preset type;

If yes, it is determined that the operation instruction satisfies the preset condition;

If not, it is determined that the operation instruction does not meet the preset condition.

In a specific implementation process, the preset type of operation instruction can be set as an interface switching instruction, such as returning to the main interface, returning to the previous page, and so on. No matter what the determination result is, the mobile terminal can normally execute the operation instruction triggered by the user through the fingerprint key without being affected by the determination result.

204. The mobile terminal judges whether the verification of the fingerprint information is successful; if yes, execute step 203; if not, execute step 205.

Specifically, it can be determined whether the operator is an unauthorized user through fingerprint verification. Among them, there are many ways to verify the fingerprint information. For example, the fingerprint information input by the operator can be compared with the preset fingerprint information database; that is, the step "judging whether the verification of the fingerprint information is successful" can specifically include :

Judging whether there is sample fingerprint information matching the fingerprint information in the sample set;

If it exists, it is determined that the verification of the fingerprint information is successful;

If it does not exist, it is determined that the verification of the fingerprint information fails.

Wherein, the sample set includes at least one sample fingerprint information. If it is determined that the verification is successful, it can be determined that the operator is an authorized user, and at this time, the operation of detecting and obtaining fingerprint information in step 203 can be continued; if the verification fails, it can be determined to a certain extent that the operator is an unauthorized user.

In the specific implementation process, in order to ensure the user experience and to prevent the operator from being aware of the monitoring operation of the mobile terminal, no matter what the verification result is, the mobile terminal can normally execute the above operation command triggered by the home button without being affected by the verification result .

205. The mobile terminal turns on the camera to collect image information of the user.

Specifically, if the verification fails, it can be considered that an unauthorized user is using the owner's device privately. At this time, the camera can be turned on to collect the operator's image information, such as face information, body information, clothing information, etc., to record the current operator information .

In the specific implementation process, it may be due to interference from external factors (such as water droplets), insufficient sensitivity of the fingerprint recognition module, etc., which may cause the fingerprint recognition module to obtain incomplete fingerprint information of the operator, resulting in fingerprint verification failure, making the mobile terminal judge. In order to avoid this misjudgment, the fingerprint information can be verified multiple times. If the verification fails for many times, it can be considered that an unauthorized user is using the owner's device privately. That is, after failing to verify the fingerprint information and before turning on the camera, the method may further include:

Obtain the cumulative number of failed verifications of the current fingerprint information;

Judging whether the cumulative number of times is greater than a preset threshold;

If greater, perform the step of turning on the camera.

Wherein, the preset threshold can be set by a person skilled in the art or a device manufacturer based on the hardware structure and performance of the device, and of course, can also be set by the user according to the installation of software in the mobile terminal. For example, the preset threshold can be set to 2 times, 3 times and so on.

206. The mobile terminal saves the fingerprint information and the image information.

Specifically, after the fingerprint information and image information are acquired, they are stored in the storage area of the mobile terminal for later viewing by authorized users. When the authorized user uses the mobile terminal next time, he can go to the designated folder, read the security report, and check whether there is any unauthorized user intruding into the mobile phone. If there is any abnormality, he can check the photo and fingerprint to determine the information of the unauthorized user.

In specific implementation, after the verification of the first fingerprint information fails, the current operator's operation records can also be recorded, such as which files have been checked, which files have been sent, copied, etc., and are stored in the security report.

In practical application, in order to avoid the misjudgment of the mobile terminal caused by the interference of external factors and the insufficient sensitivity of the fingerprint identification module, etc., resulting in wrongly acquired and wrongly saved fingerprint information and image information, occupying unnecessary storage space, the wrongly saved information can be Delete; that is, after saving the fingerprint information and the image information, the method may also include:

Judging whether the verification of the fingerprint information obtained through the home key is successful within the preset time period;

If the verification is successful, the stored fingerprint information and image information are deleted.

Wherein, the preset time period may be set by a person skilled in the art or a manufacturer, for example, the preset time period may be set as 10s, 1min and so on.

Specifically, considering the mobile terminal fingerprint recognition and home button multiplexing model, the operator will constantly use the function of the home button in the process of using the mobile terminal. Therefore, as long as the preset time period is set reasonably, it can be considered that the fingerprint information obtained within the preset time period, that is, the fingerprint information input by the same operator through the fingerprint key (ie home key), and the fingerprint information authenticating. If the verification is successful, it is considered that the previous verification failure is a misjudgment by the mobile terminal. At this point, the last saved fingerprint information and image information can be deleted to expand the storage space.

It can be seen from the above that the embodiment of the present invention provides an information acquisition method, which uses a mobile terminal to verify the authentication information input by the user, and if the verification fails, the camera is turned on to collect the image information of the operator; if the verification is successful, the screen is unlocked , when the user's fingerprint information is detected through the home button, the fingerprint information is verified. If the verification fails, the camera is turned on to collect the image information of the operator, and the fingerprint information and the collected image information are saved; this scheme can be used when the fingerprint verification fails. The fingerprint information and image information of the current operator are collected and stored in real time, and compared with the prior art, the security of information in the terminal is improved.
