Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a fingerprint payment method according to an embodiment of the present invention. The fingerprint payment method is applied to a terminal device including a fingerprint identification area, and includes the following steps:

S101. The terminal device displays a fingerprint payment interface of the first payment application.

The terminal device, also called User Equipment (UE), is a device that provides voice and/or data connectivity to the user, for example, a handheld device with a wireless connection function, an in-vehicle device, and the like. Common terminals include, for example, mobile phones, tablets, notebook computers, PDAs, mobile internet devices (MIDs), wearable devices such as smart watches, smart bracelets, pedometers, and the like.

It can be placed on the side frame of the terminal device, which is not limited in the present invention.

In another embodiment, the specific form of the fingerprint identification area may be a designated area of the touch screen of the terminal device, and a fingerprint identification module is disposed below the designated area. In the present invention, the specific location of the fingerprint recognition area placed on the touch screen of the terminal device and the size of the fingerprint collection area are not limited in the present invention.

Among them, the fingerprint recognition module is to realize the identification of individual fingerprint features through a specific sensing module. At present, the fingerprint recognition module is mainly divided into an optical fingerprint module, a capacitive fingerprint module, and a radio frequency fingerprint module.

Optionally, the fingerprint payment interface includes a dialog box for prompting the user to input a fingerprint image for payment authentication of the first payment application. For example, as shown in FIG. 2, a dialog box of "Please verify the fingerprint of the xxx application binding" pops up on the screen of the terminal device.

S102. When detecting a touch operation of the fingerprint identification area, the terminal device collects a first fingerprint image by using the fingerprint identification area.

Optionally, the terminal device collects a specific image of the first fingerprint image by using the fingerprint identification area The method includes: the terminal device acquires a normal underlying data set and an abnormal underlying data set by using a sensing electrode of the fingerprint identification module of the fingerprint identification area, where the normal underlying data set includes a plurality of normal underlying data values, and the abnormal underlying data The set includes a plurality of abnormal underlying data values; the terminal device determines the target underlying data set corresponding to the abnormal underlying data set according to the normal underlying data set; and the terminal device generates the first according to the normal underlying data set and the target underlying data set. A fingerprint image.

Further, in the above example process, the example implementation process of determining, by the terminal device, the target underlying data set corresponding to the abnormal underlying data set according to the normal underlying data set is as follows:

The terminal device determines an average value according to the plurality of normal underlying data values included in the normal underlying data set; the terminal device replaces the multiple abnormal underlying data included in the abnormal underlying data set with the average value to obtain The target underlying data set.

Or the example implementation process of determining, by the terminal device, the target underlying data set corresponding to the abnormal underlying data set according to the normal underlying data set is as follows:

The terminal device obtains a normal underlying data value with the smallest data value from the plurality of normal underlying data values included in the normal underlying data set; the terminal device replaces the multiple abnormal underlying data included in the abnormal underlying data set with the same The normal underlying data value with the smallest data value is obtained to obtain the target underlying data set.

The terminal device obtains any normal underlying data value from the plurality of normal underlying data values included in the normal underlying data set; the terminal device replaces the plurality of abnormal underlying data included in the abnormal underlying data set with the arbitrary A normal underlying data value to get the target underlying data set.

Wherein, the above bottom data value may include a capacitor and/or a voltage or the like. The sensing electrode of the fingerprint recognition module can be detected by the micro control unit MCU of the fingerprint recognition module. The sensing electrode of the fingerprint recognition module includes a plurality of normal sensing electrodes and a plurality of abnormal sensing electrodes, wherein the abnormal sensing electrodes are sensing electrodes in which an abnormality occurs. A normal underlying data set is obtained through a plurality of normal sensing electrodes, and an abnormal underlying data set is acquired through a plurality of abnormal sensing electrodes.

S103: The terminal device acquires a first random number corresponding to the first payment application, and acquires a first fingerprint template corresponding to the first random number from a record of the random number and the fingerprint template.

S104. When the first fingerprint image is successfully matched with the first fingerprint template, the terminal device performs a payment operation.

Specifically, 1) firstly maintaining a payment application table in the system. When a payment application activates the fingerprint payment function, an encryption algorithm is used to generate a random number, and the generated random number is used to identify that the payment application is using the fingerprint payment function. . The random number is then passed to a fingerprint zone (TZ), and the random number is saved in frameworks and TZ, respectively, as a voucher for the payment application at the time of fingerprint payment. 2) After the fingerprint payment function of the payment application is successfully opened, the TZ will transmit the fingerprint template ID for the fingerprint payment application payment authentication set to the frameworks when the fingerprint payment function is activated, and the TZ needs to record a table, that is, step 1 a correspondence table between the generated random number and the fingerprint template ID opened in step 2). 3) When the payment software uses the fingerprint payment, the framework first queries the random number corresponding to the payment application, and informs the TZ of the random number, and after receiving the random number, the TZ, through the table generated in step 2), queries the corresponding random number. The fingerprint template ID is then matched and authenticated by the fingerprint entered by the user when the payment is made, and the matching result is given. If the matching result is a match, the payment operation is directly performed, and if the matching result is not matched, the user is prompted to re-enter the fingerprint.

Optionally, the method further includes:

When detecting that the second fingerprint template is deleted, and the second fingerprint template is a fingerprint template for the second payment application payment authentication, the terminal device acquires a second random number corresponding to the second payment application, and The fingerprint template ID corresponding to the second random number is deleted from the record of the random number and the fingerprint template ID.

Optionally, when the second fingerprint template is deleted, the foregoing step is only deleting the second fingerprint template ID in the record of the random number and the fingerprint template ID, and the second random number corresponding to the second payment application is not deleted. That is to say, the second payment application is still in the case where the fingerprint payment function is activated. If the user uses the payment function of the second payment application at this time, the payment authentication fails because the template is not compared. In order to avoid the occurrence of the situation, after the terminal device deletes the fingerprint template ID corresponding to the second random number from the record of the random number and the fingerprint template ID, the method further includes The terminal device displays prompt information, where the prompt information is used to prompt that the fingerprint template used for the second payment application payment authentication has been deleted, and whether a new payment authentication fingerprint template is set for the second payment application. When the terminal device detects the confirmation instruction for the first prompt information, the terminal device determines whether the terminal device has at least one fingerprint template whose integrity is greater than or equal to the first threshold; And displaying, by the terminal device, the at least one fingerprint template on the display screen, and displaying related information of the at least one fingerprint template, where the integrity of the terminal device is greater than or equal to the first threshold. When the terminal device detects the click instruction of the fingerprint template i in the at least one fingerprint template, the terminal device uses the fingerprint template i as a fingerprint template for the second payment application payment authentication.

The specific interface operation diagram is shown in Figure 3. In the schematic diagram shown in FIG. 3, the at least one fingerprint template is two fingerprint templates, which are a fingerprint template of a left thumb and a fingerprint template of a right thumb.

Optionally, the integrity of the first fingerprint template and the second fingerprint template are both greater than or equal to a first threshold. That is to say, the fingerprint template set to a payment application payment authentication must be relatively complete. In addition, the integrity of the fingerprint template used for payment authentication can be avoided, and the fingerprint template used for payment authentication and the fingerprint input when the fingerprint is paid are the same fingerprint of the same finger, but the fingerprint of different parts may cause the fingerprint payment to fail. In turn, the success rate of fingerprint payment can be further improved.

Since the fingerprint entry is manually entered, not the machine entry, the user may not have a complete fingerprint when entering the fingerprint template. The solution can continuously supplement the fingerprint template during the use of the subsequent terminal device, so that the fingerprint template entered is more and more complete. The specific implementation manner of the fingerprint template is: when the fingerprint image is unlocked, if the second fingerprint image collected by the fingerprint recognition area matches the third fingerprint template, the terminal device receives the second fingerprint image. Extracting a plurality of fingerprint features not included in the third fingerprint template, and adding the plurality of fingerprint features to the third fingerprint template.

Optionally, the method further includes:

When detecting that the completeness of the third fingerprint template is greater than or equal to the first threshold, the terminal device determines whether the third fingerprint template has a repetition degree greater than or equal to one of the fingerprint templates stored in the terminal device. a second threshold; if the third fingerprint template is stored in the terminal device If the repetition degree of one of the fingerprint templates is greater than or equal to the second threshold, the terminal device prompts the user that the third fingerprint template already exists, and whether the third fingerprint template is stored.

Further optionally, the method further includes:

And receiving, by the terminal device, the third fingerprint template, and marking the third fingerprint template and the one of the fingerprint templates as duplicate fingerprint templates, so as to facilitate subsequent confirmation. The terminal device deletes the third fingerprint template if a determination deletion instruction for the above prompt is received.

It can be seen that, in the solution provided by the embodiment of the present invention, only one fingerprint template is bound to each payment application by the mapping relationship between the payment application and the random number and the mapping relationship between the random number and the fingerprint template. When the fingerprint comparison of the first payment application is performed, the terminal device compares the collected fingerprint image with the first fingerprint template bound to the first payment application. In this way, although the fingerprint template duplicated with the first fingerprint template is stored in the terminal device, the fingerprint comparison result of the first payment application is not affected, thereby improving the success rate of the fingerprint payment.
