Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Before discussing exemplary embodiments in greater detail, it should be noted that the specific structural and functional details disclosed herein of some exemplary embodiments are merely representative and are provided for purposes of describing exemplary embodiments of the present invention. The present invention may, however, be embodied in many alternate forms and should not be construed as limited to only the embodiments set forth herein.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element may be termed a second element, and, similarly, a second element may be termed a first element, without departing from the scope of example embodiments. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a keyboard generation method for security information input according to an embodiment of the present invention, including the following steps:
in step S110, key positions included in the keyboard for input as security information are determined.
The keyboard adopted by the embodiment is not a universal keyboard configured by the mobile terminal. But rather a specially configured keyboard, preferably a "soft keyboard," depending on the currently launched application. The keyboard can trigger a remote server to configure and display through the starting of a local application program, and can also be autonomously configured on a local mobile terminal by a user. In either way, the key positions of the keyboard required for inputting the safety information need to be clear.
Step S120, dividing the keys into a first set of keys and a second set of keys; when a first element in the first key position set is clicked, a second element corresponding to the first element is determined according to a preset rule, and key position information of the second element is read.
In the step, a keyboard input as safety information is divided into two key position sets, a first key position set and a second key position set, and when a first element in the first key position set is clicked, a second element corresponding to the first element is determined according to a preset rule, and key position information of the second element is read; that is, when a legal user inputs a password or other security information and some keys of the keyboard are clicked, the key information corresponding to another key is actually input. The key position information can be coding information of each key position in the keyboard.
It can be seen from the above analysis that the method provided by the embodiment of the present invention implements secure input of personal information by parsing received information according to a keyboard mapping different from a keyboard layout. In the prior art, some programs for monitoring, for example, hook functions therein, can intercept key position information, but the information is not information analyzed in the background, or information actually typed by a user, so that the user can safely input confidential information such as an account number, a password, an identity card and the like when using various tasks of a mobile phone, without worrying about stealing of the information, and the security of using the mobile terminal is greatly improved. In addition, other people cannot acquire the information actually input by the user by observing the current keyboard layout, so that the condition that other people acquire the information actually input by the user by observing the key position clicked by the user is avoided, and the safety is further improved.
And step S130, drawing and displaying the keyboard.
And after each key position in the first key position set and the second key position set is determined, keyboard drawing can be carried out, and the drawn keyboard is displayed in the mobile terminal.
In this embodiment, this step may be accomplished by two steps, namely the rendering of the key in the first set of key keys and the rendering of the key in the second set of key keys,
1) drawing a first key display in the first key set, wherein the first key display comprises a main display and a corner mark display; the main display is the key position information of the current key position, and the corner mark is the key position information of the other key position which forms a dislocation relation with the corner mark;
2) and drawing a second key position display in the second key position set, wherein the second key position display is the corresponding key position information.
Obviously, the two steps are parallel and have no sequential relation in time sequence.
It should be noted that, in practical implementation, the ratio of the number of key bits in the first set of key bits to the total number of key bits included in the keyboard does not exceed a given threshold, for example, does not exceed 1/2, and of course, other thresholds may also be adopted, which is not limited in the present invention. The reason for setting in this way is that the defects that the user input is difficult or the vision is obstructed because of too many dislocation key positions can be prevented, and the user input efficiency and the input experience are both considered while the safe input is ensured.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a keyboard generation method for inputting secure information according to another embodiment of the present invention, including the following steps:
s210, key positions included in the keyboard for input as security information are determined.
S220, the key positions are randomly arranged.
S230, dividing the key positions into a first key position set and a second key position set; in the first key position set, the key positions represented by every two elements are appointed to form a dislocation pair; when one element in the dislocation pair is clicked, key position information of the other element in the dislocation pair is read.
And S240, drawing and displaying the keyboard.
In this embodiment, the security of information input is further enhanced by increasing the random arrangement of key positions. The random arrangement of the key positions may be before the first key position set is divided, or after the first key position set is divided, although the former is adopted in the embodiment, the invention is not limited to this.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a keyboard generation method for inputting secure information according to another embodiment of the present invention, including the following steps:
s310, key positions included in the keyboard for input as security information are determined.
S320, randomly arranging the key positions.
S330, randomly arranging the elements in the first key position set into K1, K2, K3, …, K (i-1), Ki, …, K (n-1) and K (n), wherein n is the number of all the elements in the first key position set, and i and n are natural numbers; reading key position information of the element Ki when the element K (i-1) is clicked; the element K (i-1) and the element Ki form a dislocation relation.
In practical implementation, the ratio of the number of key bits in the first set of key bits to the total number of key bits included in the keyboard does not exceed a given threshold, for example, the threshold may be 1, and of course, other thresholds may also be adopted, which is not limited in the present invention. The reason for this is that all the keys can be dislocated, further ensuring that the user can input confidential information such as account number, password and ID card safely when using each task of the mobile phone, and greatly improving the security of using the mobile terminal.
And S340, drawing and displaying the keyboard.
An example of a keyboard generation method for secure information input is given below in conjunction with fig. 4, comprising the steps of:
in step S410, when the user needs to input personal password information, key positions included in the keyboard for input as security information are determined.
Step S420, the key positions are randomly arranged.
Step S430, dividing all the key positions into a first key position set and a second key position set, and randomly extracting a part of the key positions in the first key position set to be mutually staggered; in particular to a method for preparing a high-performance nano-silver alloy,
randomly extracting a part (the extracted quantity cannot exceed half of the total key position) from all the key position numbers and character lists needing to be drawn and placing the part into a first set A to be dislocated, and randomly extracting a part of key position information which is consistent with the size of the first set A and does not contain the first set A and placing the part into a second set B to be dislocated.
And step S440, drawing and displaying the keyboard.
When the keyboard is drawn, reading corresponding key position information in a first set A and a first set B to be dislocated for drawing, firstly judging whether the current key position exists in the first set A, if so, reading the information in a corresponding second set B, and labeling the corresponding information in the second set B at the lower right corner of the current key position until all random key position information is drawn.
And when the keyboard is drawn, the corresponding key position information with dislocation is marked on the lower right corner of the key position with dislocation.
When the user clicks the keyboard, firstly judging whether the current key position is a random key position, if so, reading the dislocated key position information, otherwise, normally reading the normal key position information.
Referring to fig. 5, fig. 5 is a schematic diagram of a keyboard generated by the keyboard generation method for inputting security information. When the user inputs the input, capturing and monitoring the input, judging whether the currently input characters are in the first set or the second set, if so, exchanging the characters at the same coordinate position with the corresponding set to finish the dislocation reduction processing, otherwise, directly inputting the original input information. For example: the first set is { t,3,6,9, m }, and the second set is { w,7,8,0, x }; when t,3 is clicked, the actual input information is w,7, so when the user needs to obtain test123, the actual input information is wesw127, and the result is subjected to dislocation restoration processing to obtain test 123.
Referring to fig. 6, it is a block diagram of a keyboard generation apparatus for inputting secure information according to an embodiment of the present invention, the keyboard generation apparatus includes:
a key position determining module 60 for determining key positions included in the keyboard for inputting as security information.
The keyboard adopted by the embodiment is not a universal keyboard configured by the mobile terminal. But rather a specially configured keyboard, preferably a "soft keyboard," depending on the currently launched application. The keyboard can trigger a remote server to configure and display through the starting of a local application program, and can also be autonomously configured on a local mobile terminal by a user. In either way, the key positions of the keyboard required for inputting the safety information need to be clear.
A dividing module 61, which divides the keys into a first set of keys and a second set of keys; when a first element in the first key position set is clicked, determining a second element corresponding to the first element according to a preset rule, and reading key position information of the second element;
in the step, a keyboard input as safety information is divided into two key position sets, a first key position set and a second key position set, and when a first element in the first key position set is clicked, a second element corresponding to the first element is determined according to a preset rule, and key position information of the second element is read; that is, when a legal user inputs a password or other security information and some keys of the keyboard are clicked, the key information corresponding to another key is actually input. The key position information can be coding information of each key position in the keyboard.
It can be seen from the above analysis that the method provided by the embodiment of the present invention implements secure input of personal information by parsing received information according to a keyboard mapping different from a keyboard layout. In the prior art, some programs for monitoring, for example, hook functions therein, can intercept key position information, but the information is not information analyzed in the background, or information actually typed by a user, so that the user can safely input confidential information such as an account number, a password, an identity card and the like when using various tasks of a mobile phone, without worrying about stealing of the information, and the security of using the mobile terminal is greatly improved. In addition, other people cannot acquire the information actually input by the user by observing the current keyboard layout, so that the condition that other people acquire the information actually input by the user by observing the key position clicked by the user is avoided, and the safety is further improved.
And the display module 62 is used for drawing and displaying the keyboard.
And after each key position in the first key position set and the second key position set is determined, keyboard drawing can be carried out, and the drawn keyboard is displayed in the mobile terminal.
In this embodiment, the module may further include a first drawing unit 621 and a second drawing unit 622 for performing the drawing of the key in the first set of key bits and the drawing of the key in the second set of key bits, wherein:
a first rendering unit 621, configured to render a first key display in the first set of key locations, the first key display including a main display and a logo display; the main display is the key position information of the current key position, and the corner mark is the key position information of the other key position which forms a dislocation relation with the corner mark;
and a second rendering unit 622 for rendering a second key display of the second set of key keys, the second key display being its corresponding key information.
Obviously, the two drawing units are parallel and have no precedence relationship in the time sequence of function implementation.
It should be noted that, in practical implementation, the ratio of the number of key bits in the first set of key bits to the total number of key bits included in the keyboard does not exceed a given threshold, for example, does not exceed 1/2, and of course, other thresholds may also be adopted, which is not limited in the present invention. The reason for setting in this way is that the defects that the user input is difficult or the vision is obstructed because of too many dislocation key positions can be prevented, and the user input efficiency and the input experience are both considered while the safe input is ensured.
Referring to fig. 7, fig. 7 is a block diagram of a keyboard generation apparatus for inputting secure information according to another embodiment of the present invention, including:
a key position determining module 70 for determining key positions included in the keyboard for inputting as security information.
And an arranging module 71 for randomly arranging the key positions.

And the display module 73 is used for drawing and displaying the keyboard.
In this embodiment, the security of information input is further enhanced by increasing the random arrangement of key positions. The random arrangement of the key positions may be before the first key position set is divided, or after the first key position set is divided, although the former is adopted in the embodiment, the invention is not limited to this.

In practical implementation, the ratio of the number of key bits in the first set of key bits to the total number of key bits included in the keyboard does not exceed a given threshold, for example, the threshold may be 1, and of course, other thresholds may also be adopted, which is not limited in the present invention. The reason for this is that all the keys can be dislocated, further ensuring that the user can input confidential information such as account number, password and ID card safely when using each task of the mobile phone, and greatly improving the security of using the mobile terminal.
And the display module 83 is used for drawing and displaying the keyboard.
