Description

Mobile equipment and safe input method thereof

Technical Field

The present application relates to the field of computers, and in particular, to a mobile device and a secure input method thereof.

Background

With the popularization and application of information technology, smart phones, tablet computers, and other mobile computing devices go deep into every corner in people's work and life. Some tasks may not pose a serious security risk, such as taking a picture with a camera of a mobile device. However, some tasks may pose security risks, such as using a mobile device to access an online banking transaction website to perform mobile payments.

The existing mobile device usually adopts a touch screen form to display and input information, for example, a password is often input through the touch screen, so as to complete functions of unlocking, mobile payment and the like. To ensure security, one solution is to require the password to have a minimum length (e.g., at least 8 characters) and/or a required entropy (e.g., having at least one letter and at least one number).

However, many users are unable to remember cumbersome passwords, eventually choose relatively simple passwords, and may be easily broken or otherwise guessed by brute force attacks. This is particularly true for mobile device users because the physical or virtual (on-screen) keyboard form factor is small in mobile devices, making password entry tedious and laborious. Further, the touch screen of the mobile device is worn to different degrees because the surface of the touch screen of the mobile device is marked after long-term touch. This situation may also lead to problems of password leakage or uneven wear of the touch screen.

Detailed Description

The technical solutions in the embodiments of the present application are clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The present application provides a mobile device, as shown in fig. 1, the mobile device 100 includes the following components: a touch screen 110 and a processor 120, wherein:

the touch screen 110 is used for displaying information and receiving input, wherein a specific hardware structure of the touch screen 110 may be implemented by using a commercially available touch screen, which is not described herein again.

And the processor 120 is connected with the touch screen 110 and is used for judging a less-used area of the touch screen and responding to the calling of the input interface so that the touch screen displays the input interface in the less-used area.

Wherein the mobile device 100 performs the working method in the embodiments described below.

Example one

As shown in fig. 2, the secure input method of the present application includes the following steps:

step S210, judging a less used area of the touch screen;

recording the position of the touch screen displaying the input keyboard each time, counting the position information of the displayed input keyboard every preset time, and judging which areas of the display screen display the input keyboard less, wherein the areas are the areas which are used less.

Step S220, responding to the calling of the input interface, and displaying the input interface in a less used area;

when the system of the mobile device issues a command to invoke an input interface, the input interface is displayed in a less used area.

The less used regions in step S210 may be sorted, and the least used region may be selected for display in the input interface.

Example two

Further, on the basis of the first embodiment, the method further includes the following steps:

when the password information is input on the input interface, prompting the user to input the password according to a specific sequence according to the use habit of the user.

Specifically, after the less-used area on the touch screen displays the input interface, the user performs input. And responding to the instruction of inputting the password information, and prompting the user to input the passwords according to the fixed sequence according to the use habit of the user.

For example, if the user is accustomed to the right hand-held screen, the user is prompted that all passwords need to be fixed to enter a certain letter on the left side of the input interface, for example, the password is 1234, the user is prompted that each password needs to be entered before 0 on the left side of the input interface, and the password becomes 01020304.

The using habits of the user are obtained according to user modeling, and the user modeling comprises the following steps:

step P1, recognizing and recording the input mode of the user;

including the main area input by the user, the input frequency, the use duration and other information.

And step P2, inputting the input mode of the user into the modeling tool to obtain the use habit of the user.

The modeling tool is established in advance and comprises the following steps:

step M1, pre-constructing a user use habit library;

and the user use habit library stores a large amount of use habit preference information of the users.

Step M2, extracting the habit library used by the user;

and extracting required information from the user use habit library. For example by age or frequency of use.

Step M4, mining the frequent mode used by the user;

and mining frequent patterns of the use habits of the users from the extracted information. Such as a left-hand mode, a right-hand mode, etc.

Step M5, generating association rules according to the mined frequent patterns, wherein the statistical user use habits and the generated association rules form a user model;

taking the left-handed mode as an example, an association rule is generated for the mode according to the usage habit of the user, for example, a rule that the left-side input exceeds a predetermined threshold value.

EXAMPLE III

The display of the input interface and the working method for inputting the password are described through the first embodiment and the second embodiment, and further, after the input interface is initially displayed in an area which is less used by the touch screen, the application further includes a third embodiment that the input interface is displayed along with the movement of the user when the user moves the hand.

The processor detects the operation of a finger of a user on the touch screen, calculates the pressing time length of the finger when the finger pressing operation is detected, and displays an input interface at the current position of the finger when the time length threshold value is met.

Further, the processor can detect the number of fingers, judge the specific positions of the fingers and display the input interface according to the specific position distribution of the fingers. For example, when it is determined that the finger is 4 fingers, the position of the middle finger is determined, and the input interface is displayed in accordance with the position of the middle finger.
