Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
Referring to fig. 1, a flowchart of an embodiment of a method for touch operation provided by the present invention is shown, where the method is executed by a touch device, and specifically includes the following steps:
the method for touch operation provided by the embodiment of the invention comprises the following steps:
s1, responding to the touch operation of a user, and scanning the fingerprint image on each touch screen point of the touch operation in real time;
s2, determining the operation type of the touch operation according to the position and the operation duration of each touch point of the touch operation;
s3, verifying the identity of the user according to the operation type of the touch operation and the fingerprint image;
and S4, after the identity authentication of the user is successful, executing an operation instruction corresponding to the touch operation.
Compared with the traditional touch operation, the method provided by the embodiment of the invention scans the fingerprint image of the touch operation in real time when the user performs the touch operation on the touch equipment, does not need the user to input the fingerprint information in the designated area of the application software in the touch equipment or the touch equipment first, unlocks the application software or the touch equipment after the identity of the user is successfully verified, and then the user can perform the touch operation on the application software or the touch equipment; and after the identity of the user to be verified is successful, the operation instruction of the touch operation is executed, so that the information security in the touch operation process can be ensured.
There are three embodiments for performing identity authentication according to the operation type of the touch operation and the fingerprint image, and each embodiment is described in detail below:
in an embodiment, in the step S3, the verifying the identity of the user according to the operation type of the touch operation and the fingerprint image specifically includes:
when the operation type of the touch operation is determined to be a screen sliding operation, matching the fingerprint image on each touch screen point of the touch operation with a preset standard fingerprint image to obtain a fingerprint matching value of each touch screen point, and selecting the fingerprint matching value with the highest value from the fingerprint matching values to verify the identity of the user;
if the selected fingerprint matching value is larger than a first matching threshold value, the identity verification of the user is successful;
if the selected fingerprint matching value is larger than a second matching threshold and smaller than the first matching threshold, obtaining a screen-sliding track according to the position of each touch screen point of the touch operation, and identifying the coincidence degree of the screen-sliding track and the historical screen-sliding track of the user; when the coincidence degree is larger than the coincidence threshold value, the identity verification of the user is successful; when the coincidence degree is smaller than the coincidence threshold value, the identity verification of the user fails; wherein the second match threshold is less than the first match threshold;
and if the selected fingerprint matching value is smaller than the second matching threshold value, the identity authentication of the user fails.
It should be noted that, when the operation type of the touch operation is a screen-swiping operation, the user slides on the screen at a high speed, which may cause a part of the fingerprint image of the user to be erased along the sliding direction, so that the fingerprint image scanned in real time is blurred and difficult to identify, and thus each scanned fingerprint image is matched with the standard fingerprint image, and the fingerprint matching value with the highest fingerprint matching value is selected to be compared with the preset matching threshold value, so that the probability of passing the identity authentication can be improved. However, the fingerprint image scanned by the screen-sliding operation is generally difficult to confirm, and when the fingerprint matching value for verification does not reach the set matching threshold value, the user may need to perform the screen-sliding operation again for many times, so that the user is inconvenient to operate, and the identity of the user is verified by combining the fingerprint identification with the historical screen-sliding track used by the user.
The information of the screen-sliding track refers to the path length and the path inclination angle of the screen-sliding track, and the contact ratio of the screen-sliding track and the historical screen-sliding track of the user refers to: and comparing the path length of the screen-scratching track with the path length of the historical screen-scratching track of the user, comparing the path inclination angle of the screen-scratching track with the path inclination angle of the historical screen-scratching track of the user, and averaging the ratio obtained by comparing the path inclination angle of the screen-scratching track with the path inclination angle of the historical screen-scratching track of the user to obtain the contact ratio, namely the contact ratio.
In another embodiment, in the step S3, the verifying the identity of the user according to the operation type of the touch operation and the fingerprint image specifically includes:
when the touch operation type is determined to be dragging operation, matching the fingerprint image on the last touch screen point of the touch operation with a preset standard fingerprint image to obtain a fingerprint matching value of the last touch screen point for verifying the identity of the user;
if the fingerprint matching value is larger than a first matching threshold value, the identity verification of the user is successful;
and if the fingerprint matching value is smaller than the first matching threshold value, the identity verification of the user fails.
It should be noted that the dragging operation is similar to the screen swiping operation, the fingerprint image obtained when the user touches the screen is difficult to identify due to the dragging effect, but the fingerprint image at the last dragged drop point is generally the highest in definition, so in the embodiment of the present invention, an authentication operation different from the screen swiping operation is adopted, and only the fingerprint image at the last touch screen point of the dragging operation needs to be matched with the standard image, so that the time for authenticating the identity of the user is reduced, and the efficiency is improved.
In another embodiment, in the step S3, the verifying the identity of the user according to the operation type of the touch operation and the fingerprint image specifically includes:
when the operation type of the touch operation is determined to be a click operation, matching the fingerprint image on each touch screen point of the touch operation with a preset standard fingerprint image to obtain a fingerprint matching value of each touch screen point, and selecting the fingerprint matching value with the highest numerical value from the fingerprint matching values to verify the identity of the user;
if the selected fingerprint matching value is larger than a first matching threshold value, the identity verification of the user is successful;
and if the selected fingerprint matching value is smaller than the first matching threshold value, the identity authentication of the user fails.
It should be noted that the clicking operation includes clicking, long-time pressing, double-clicking or clicking on a plurality of different touch screen points, and the like, and because the clicking operation does not cause the fingerprint image blur due to sliding or dragging, and the touch screen points of the clicking operation are relatively few, the fingerprint image on each touch screen point is respectively matched with the pre-configured standard fingerprint image, and the occupied time is short, the fingerprint image on each touch screen point can be respectively matched with the pre-configured standard fingerprint image, and then the fingerprint matching value with the highest value is selected from the fingerprint matching values for identity authentication, so that the efficiency of identity authentication is not affected.
Further, the method for touch operation further includes:
after the user fails in identity authentication, displaying reminding information of operation failure on the screen, and adding one to the count value;
and when the count value is larger than an early warning threshold value, freezing an account of the user on the application software operated by the touch operation.
It should be noted that, by setting an early warning threshold, the information security of the user can be further enhanced, and it is avoided that other people steal the personal information in the touch device or the application software on the touch device.
The touch operation method provided by the embodiment of the invention can be used for scanning the fingerprint image of the user in real time while acquiring the touch operation information of the user, executing the operation instruction corresponding to the touch operation after the identity of the user is successfully verified according to the type of the touch operation and the fingerprint image, and ensuring the information safety in the touch operation process.
