Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to explain the technical solution of the present application, the following description will be given by way of specific examples.
The specific embodiment is as follows:
a first operation response method provided by the embodiment of the present application is described below with reference to fig. 1, which is detailed as follows:
step S101, after receiving an operation instruction, collecting a fingerprint image through a fingerprint identifier under a touch screen;
in this step, the operation instruction refers to an instruction that requires verification of operation validity, for example, an unlocking instruction, a payment instruction, and the like of the mobile terminal, and for example, if the operation instruction is an unlocking instruction, the mobile terminal receives the operation instruction when the user presses the fingerprint identifier. The mobile terminal includes a mobile phone, a tablet computer, and the like.
The fingerprint identifier of this step comprises an optical fingerprint identifier.
Step S102, if the collected fingerprint image is not matched with a prestored fingerprint image, acquiring a sliding track of a finger on the touch screen;
in this embodiment, the sliding track of the finger on the touch screen refers to the sliding track of the finger in the area of the touch screen right above the fingerprint identifier, as shown in fig. 2, the area of the touch screen right above the fingerprint identifier is an oval area in fig. 2.
Prior to step S101, comprising: storing the fingerprint images input by the user, wherein the number of the fingerprint images is more than or equal to 1. Specifically, a fingerprint image input by a user is received at a fingerprint input interface and stored.
And step S103, responding to the operation instruction if the acquired sliding track on the touch screen is matched with a pre-stored track.
In this embodiment, when storing the fingerprint image entered by the user, the user is prompted to enter a sliding track in the area where the fingerprint image is entered, so that when the collected fingerprint image is not matched with the pre-stored fingerprint image, whether to respond to the received operation instruction can be further determined according to the sliding track. Of course, if the user does not enter the sliding trajectory, the step S103 is not executed.
In the embodiment of the application, because after judging that the fingerprint image of gathering does not match with the fingerprint image of prestoring, it is in to acquire the finger gliding orbit on the touch-sensitive screen, and when acquireing gliding orbit matches with the orbit of prestoring on the touch-sensitive screen, the response operating instruction, consequently, can be through the matching selection again of gliding orbit whether respond to operating instruction to can improve the promptness of responding to operating instruction.
In some embodiments, when the acquired fingerprint image is set to partially match with the pre-stored fingerprint image, whether to respond to the received operation instruction is further determined. At this time, the step S102 includes:
and if the matching degree of the acquired fingerprint image and the pre-stored fingerprint image is greater than or equal to a first preset matching degree threshold value and less than or equal to a second preset matching degree threshold value, acquiring the sliding track of the finger on the touch screen.
The first preset matching degree threshold is greater than 0, for example, may be set to 10%, 20%, and the like, and the second preset matching degree threshold is less than 70%, for example, may be set to 40%, 50%.
In this embodiment, if the user who sends the operation instruction is a valid user, the fingerprint image acquired by the mobile terminal should have a part of fingerprint image successfully matched with the pre-stored fingerprint image in a rough probability. Therefore, the sliding track of the finger on the touch screen is acquired after the acquired fingerprint image is partially matched with the pre-stored fingerprint image, and the probability of identifying the fingerprint image of an illegal user can be reduced.
In some embodiments, if the matching degree between the collected fingerprint image and the pre-stored fingerprint image is smaller than a first preset matching degree threshold, the motion of acquiring the track of the finger sliding on the touch screen is not executed.
Of course, if the collected fingerprint image is matched with the pre-stored fingerprint image, for example, the matching degree of the collected fingerprint image and the pre-stored fingerprint image is equal to 100%, or the matching degree of the collected fingerprint image and the pre-stored fingerprint image is greater than a third preset matching degree threshold, for example, when the third preset matching degree threshold is 80% and the matching degree of the collected fingerprint image and the pre-stored fingerprint image is greater than 80%, the collected fingerprint image and the pre-stored fingerprint image are determined to be matched, and then the received operation instruction is responded.
In some embodiments, the second operation response method provided by the embodiment of the present application as shown in fig. 3:
step S201, after receiving an operation instruction, collecting a fingerprint image through a fingerprint identifier under a touch screen;
the step S201 is the same as the step S101, and is not described again here.
Step S202, if the matching degree of the collected fingerprint image and the prestored fingerprint image is greater than or equal to a first preset matching degree threshold value and less than or equal to a second preset matching degree threshold value, acquiring a fingerprint image track corresponding to continuous sliding of a finger on the touch screen;
in this step, the fingerprint image trajectory refers to a trajectory formed by a plurality of fingerprint images acquired during the continuous sliding of the finger. Continuous sliding here refers to continuous sliding of the finger in the area of the touch screen directly above the fingerprint identifier.
And step S203, responding to the operation instruction if the acquired fingerprint image track corresponding to the continuous sliding of the finger on the touch screen is matched with the prestored fingerprint image track.
The fingerprint image track is matched with a pre-stored fingerprint image track, namely the similarity of the fingerprint image track and the pre-stored fingerprint image track is greater than or equal to a preset fingerprint image track matching degree, and the preset fingerprint image track matching degree is less than or equal to 100%.
In the embodiment, after the fingerprint image matching fails, the fingerprint image track is continuously acquired for matching, and a new matching mode is added, so that the probability of successful matching is improved, and the timeliness of responding to the operation instruction is further improved.
In some embodiments, in order to improve the probability of identifying the fingerprint image trajectory of a valid user, when acquiring a fingerprint image trajectory corresponding to a continuous finger sliding on the touch screen, only the fingerprint image trajectory within a preset duration is acquired.
In some embodiments, the third operation response method provided by the embodiment of the present application as shown in fig. 4:
step S301, after receiving an operation instruction, collecting a fingerprint image through a fingerprint identifier under a touch screen;
step S301 is the same as step S101 of the above embodiment, and is not described again here.
Step S302, if the matching degree of the collected fingerprint image and the prestored fingerprint image is greater than or equal to a first preset matching degree threshold value and less than or equal to a second preset matching degree threshold value, acquiring a coordinate track of the finger sliding at a specified point on the touch screen;
in this step, in the process of fingerprint identification by a user, the user presses the touch screen directly above the fingerprint identifier, and then the touch screen of the mobile terminal collects coordinates of a designated point of a finger on the touch screen, where the designated point includes any pressing point of the finger on the touch screen, such as the center of the finger, and then obtains a sliding coordinate track of the designated point on the touch screen.
And step S303, if the obtained coordinate track of the finger sliding on the appointed point on the touch screen is matched with a prestored coordinate track, responding to the operation instruction.
The obtained coordinate track of the finger sliding on the appointed point on the touch screen is matched with a prestored coordinate track, namely the similarity of the coordinate track and the prestored coordinate track is greater than or equal to a preset coordinate track matching degree, and the preset coordinate track matching degree is less than or equal to 100%.
In the embodiment, after the fingerprint image matching fails, the sliding coordinate track of the designated point is continuously acquired for matching, and a new matching mode is added, so that the matching success probability is improved, and the timeliness of responding to the operation instruction is further improved.
In some embodiments, in order to improve the probability of identifying the coordinate trajectory of the designated point sliding of the legal user, when the coordinate trajectory of the designated point sliding is obtained, only the coordinate trajectory of the designated point sliding within a preset time length is obtained.
In some embodiments, it may be determined whether to respond to the received operation instruction through 3 matching manners, where the operation responding method further includes:
if the acquired fingerprint image track corresponding to continuous sliding of the finger on the touch screen is not matched with the prestored fingerprint image track, acquiring a coordinate track of sliding of the finger on an appointed point on the touch screen;
and responding to the operation instruction if the obtained coordinate track of the finger sliding on the appointed point on the touch screen is matched with the prestored coordinate track.
In this embodiment, when the acquired fingerprint image is not matched with the pre-stored fingerprint image and the acquired fingerprint image track corresponding to the continuous sliding of the finger on the touch screen is not matched with the pre-stored fingerprint image track, whether the sliding coordinate track of the designated point meets the requirement is continuously judged, if the sliding coordinate track of the designated point meets the requirement, the received operation instruction is responded, and whether the received operation instruction is responded is judged through multiple matching modes, so that the timeliness of responding the operation instruction is improved.
In some embodiments, it may be determined whether to respond to the received operation instruction through other 3 matching manners, where the operation responding method further includes:
if the obtained coordinate track of the finger sliding on the appointed point on the touch screen is not matched with the pre-stored sliding track, obtaining a fingerprint image track corresponding to the finger continuously sliding on the touch screen;
and responding to the operation instruction if the acquired fingerprint image track corresponding to the continuous sliding of the finger on the touch screen is matched with the pre-stored fingerprint image track.
In the embodiment, whether the received operation instruction is responded is judged through various matching modes, so that the timeliness of responding to the operation instruction is improved.
In some embodiments, if the operation instruction is an unlocking instruction, matching the acquired trajectory sliding on the touch screen with a pre-stored trajectory, and after responding to the operation instruction, the method includes:
and detecting whether a preset application is started, if so, automatically locking the screen until the collected fingerprint image is successfully matched with the prestored fingerprint image, and unlocking the screen.
The preset application refers to an application related to the property of the user, such as various bank-type applications, payment-type applications, and the like.
When the response of the operation instruction is realized by matching the sliding track, the acquired fingerprint image is not completely matched with the prestored fingerprint image, so that the screen is automatically locked after the screen is unlocked and the preset application is started in order to ensure the property safety of a user. Optionally, the user is prompted to perform fingerprinting again. After the fingerprint image of the user is collected, the fingerprint image is matched with a prestored fingerprint image, if the fingerprint image is matched successfully, the screen is unlocked, and if the fingerprint image is matched and identified, the screen is continuously locked.
In some embodiments, if the operation instruction is a payment instruction, responding to the operation instruction if the acquired track sliding on the touch screen matches a pre-stored track includes:
if the acquired sliding track on the touch screen is matched with a pre-stored track, judging whether the current payment amount is smaller than or equal to a preset amount, and responding to the payment instruction if the current payment amount is smaller than or equal to the preset amount. And if the current payment amount is larger than a preset amount, not responding to the payment instruction.
In this embodiment, if the operation instruction is a payment instruction, it is determined whether the payment amount requested by the payment instruction is less than or equal to a preset amount, if so, the payment instruction is responded, otherwise, the payment instruction is not responded. Because when the payment amount requested by the payment instruction is less than or equal to the preset amount, the payment instruction is responded, otherwise, the payment instruction is not responded, therefore, the convenience of payment can be improved, and the large-amount property safety of the user can be ensured.
