- the embodiment prompts the user to input a fingerprint for identification, thereby verifying whether the user is a legitimate user according to the input fingerprint.
- the fingerprint input by the user may be referred to as a fingerprint to be recognized.
- step S102 in response to the user inputting the fingerprint to be identified, the matching priority of each reserved fingerprint in the preset fingerprint database is determined; wherein the preset fingerprint database stores a plurality of fingerprints reserved by the user.
- the fingerprint storage library is preset in the embodiment, and the fingerprint reserved by the user is stored in the fingerprint database, and the fingerprint is multiple. It should be noted that, in the scenario in which the multi-fingerprint is used to authenticate the fingerprint, the solution is to solve the problem of how to improve the identity verification efficiency in the case of multiple reserved fingerprints.
- the user can input a fingerprint in the fingerprint input area.
- the matching priority is determined for each fingerprint data in the preset fingerprint database. It should be noted that the matching priority may be used to represent the situation in which the user uses the reserved fingerprint.
- each of the reserved fingerprints is determined to have a corresponding matching priority, and the matching priorities have a high and low order, and the matching order of the matching priorities may indicate that the user uses the priority order of the reserved fingerprints. The higher the matching priority, the more frequently the user uses the reserved fingerprint.
- Step S103 According to the ranking of the matching priorities, the reserved fingerprints are matched with the fingerprints to be identified in order to obtain an identity verification result.
- the reserved fingerprints are sequentially matched with the fingerprints to be recognized by the user according to the determined ranking of the matching priorities.
- a reserved fingerprint matches the fingerprint to be identified. Then, a verification result indicating that the authentication is successful is generated, and the matching process is ended. If all the reserved fingerprints in the preset fingerprint database are matched, and there is no reserved fingerprint matching the fingerprint to be identified, a verification result indicating that the authentication fails is generated.
- the identity verification method can prompt the user to input the fingerprint to be identified for identity verification in response to the user opening the operation of the identity verification program, and after the user inputs the fingerprint data to be identified.
- the respective matching priorities of the preset fingerprints in the preset fingerprint database are determined, wherein the matching order of the matching priorities may indicate the priority order of the users for each reserved fingerprint, so that the matching priorities are sorted according to the level of each matching priority.
- the respective reserved fingerprints are sequentially compared with the fingerprint to be identified, thereby obtaining the result of the identity verification.
- the present embodiment does not randomly compare the reserved fingerprint with the fingerprint to be identified, but determines the comparison order of the reserved fingerprints according to the determined matching priority, taking into account the user's fingerprint. Usage, which increases the probability of obtaining authentication results with fewer matching times, which improves the efficiency of authentication and better user experience.
- each reserved fingerprint in the preset fingerprint database is bound to a variable, and the variable stores the matching number of the reserved fingerprint.
- the number of matches indicates the total number of times the reserved fingerprint matches the fingerprint to be recognized by the user before the authentication. It should be noted that the fingerprint to be identified herein is not the fingerprint to be recognized input by the user in step S102 in the above embodiment, but the fingerprint input by the user during the identity verification process before the execution of the embodiment.
- step S102 in the foregoing embodiment in response to the user inputting the fingerprint to be recognized, and determining the matching priority of each reserved fingerprint in the preset fingerprint database may be the following step A1.
- Step A1 In response to the user inputting the fingerprint to be identified, the matching priority of each of the reserved fingerprints is generated according to the order of the matching times of the reserved fingerprints.
- the preset fingerprint database includes three reserved fingerprints: reserved fingerprint 1, reserved fingerprint 2, and reserved fingerprint 3, and the corresponding matching times are 13 times, 4 times, and 8 times, and three reserved fingerprints. Between the number of matches The order is high, low, 13, 8, and 4. Therefore, the matching priorities generated for the three reserved fingerprints are reserved fingerprint 1, reserved fingerprint 3 and reserved fingerprint 2, that is, the reserved fingerprint 1 has the highest matching priority, followed by the reserved fingerprint 3, and finally The fingerprint 2 is reserved, and in this order, the fingerprint data to be identified is sequentially compared.
- the number of matching of multiple reserved fingerprints is the same, for example, the number of matches of the reserved fingerprint 1 and the reserved fingerprint 2 is 8.
- the matching priority of the reserved fingerprint needs to be adjusted.
- a method for adjusting the matching priority is to pre-record the time point at which each of the reserved fingerprints matches the fingerprint to be recognized by the user last time, according to the sequence of successful matching time points.
- the matching priority of the reserved fingerprints with the same number of matches is adjusted.
- step S102 in response to the user inputting the fingerprint to be recognized, the matching priority of each of the reserved fingerprints may be specifically included according to the order of the matching times of the reserved fingerprints.
- steps S201 to S202 in response to the user inputting the fingerprint to be recognized, the matching priority of each of the reserved fingerprints may be specifically included according to the order of the matching times of the reserved fingerprints.
- step S201 in response to the user inputting the fingerprint to be identified, the initial matching priority of each of the reserved fingerprints is determined according to the order of the matching times of the respective reserved fingerprints.
- Step S202 If there is a case where the initial matching priorities are the same, the same initial matching priority is adjusted according to the sequence of the recorded time points.
- the initial matching priority is determined according to the order of the matching times, and the initial matching priority is determined to be the same. If the same situation exists, the same initial matching priority is adjusted.
- the adjustment method is in accordance with the order of the time points of the last matching success of each reserved fingerprint of the record. Specifically, the time point is prior, and the initial matching priority of the reserved fingerprint corresponding to the time point is raised.
- the initial matching priority of the reserved fingerprint 2 and the reserved fingerprint 3 is the same, but the time when the last time the two matching the fingerprint to be identified is successful is 11:33, June 4, respectively. At 11:35, the time point for the fingerprint 2 is reserved before the fingerprint 3 is reserved. Therefore, the initial matching priority of the reserved fingerprint 2 is raised, so that the final matching priority is: reserved fingerprint 1 > reserved fingerprint 2> Reserved fingerprint 3.
- the implementation manner can solve the problem of how to determine the matching priority in the case that the number of reserved fingerprint matching times is the same. Moreover, in the process of solving this problem, the case where the user recently uses each reserved fingerprint is considered. Because the order in which users use fingerprints is often determined by usage habits, the order of using fingerprints in the near future will prompt the matching priority in this authentication. Therefore, according to the order of time points, the adjustment is made. Matching priorities can improve the efficiency of authentication and the user experience is better.
- the other way to adjust the matching priority may be to record the last reserved fingerprint matching the fingerprint to be recognized by the user, if the reserved fingerprint is exactly the same as other reservations. If the fingerprint is the same, the matching priority of the reserved fingerprint is adjusted.
- step S102 in the foregoing embodiment in response to the user inputting the fingerprint to be recognized, the matching priority of each of the reserved fingerprints is generated according to the order of the matching times of the reserved fingerprints.
- the following steps S301 to S302 may be specifically included.
- step S301 in response to the user inputting the fingerprint to be identified, the initial matching priority of each of the reserved fingerprints is determined according to the order of the matching times of the respective reserved fingerprints.
- the initial matching priority is determined according to the order of the number of reserved fingerprint matching times. For example, the matching times of the three reserved fingerprints (reserved fingerprint 1, reserved fingerprint 2, and reserved fingerprint 3) are 13 times, 8 times, and 8 times, respectively, and correspondingly, the initial matching priorities of the three reserved fingerprints are respectively.
- Step S302 If the recorded initial fingerprint has the same initial matching priority as the other reserved fingerprints, the initial matching priority of the reserved fingerprint is increased.
- the initial matching priority of the reserved fingerprint of the last matching success of the record is determined to be the same as that of the other reserved fingerprints.
- the recorded fingerprint of the last matching success is the reserved fingerprint 3, and its initial matching priority is the same as that of the reserved fingerprint 2.
- the manner of increasing may be: raising the initial matching priority of the reserved fingerprint to the previous digit of the same reserved fingerprint, such as raising the initial matching priority of the reserved fingerprint 3 to the reserved The previous digit of fingerprint 2, and thus the final matching priority is: reserved fingerprint 1 > reserved fingerprint 3 > reserved fingerprint 2.
- the manner of raising may also be to raise the initial priority of the recorded reserved fingerprint to the highest, such as to reserve The initial matching priority of the fingerprint 3 is raised to the previous digit of the reserved fingerprint 1, so that the final matching priority is: reserved fingerprint 3> reserved fingerprint 1> reserved fingerprint 2.
- the implementation manner can solve the problem of how to determine the matching priority in the case that the number of reserved fingerprint matching times is the same. Moreover, the implementation manner not only considers the total number of used fingerprints, but also considers the latest usage of the reserved fingerprints. According to the latest use of the reserved fingerprints, the matching priority in the current authentication is performed. Adjustment can improve the efficiency of authentication and better user experience.
- the matching number of the reserved fingerprints matching the fingerprint to be identified is incremented by one to achieve matching of the reserved fingerprints. The number of updates.
- step S101 to step S103 in FIG. 4 can refer to step S101 to step S103 in FIG. 1 described above, and details are not described herein. Only step S104 will be described below.
- Step S104 If the identity verification result is a failure, display an alternate identity verification interface, so that the user performs identity verification on the candidate identity verification interface; wherein the candidate identity verification decryption includes password verification and decryption. Or graphics verification decryption.
- an alternate authentication module can be invoked.

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是
全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参照图1，其示出了本申请提供的身份验证方法一个实施例的流程。该实施例可以但不限定应用在移动终端上，移动终端如手机、平板电脑、掌上电脑及便携式计算机等。如图1所示，该实施例可以具体包括步骤S101～步骤S103。
步骤S101：响应用户开启目标程序的操作，提示用户输入待识别指纹；其中，所述目标程序为需要进行身份验证的程序。
其中，移动终端上的某些程序在开启时，是需要身份验证的。如开机程序以及支付宝、微信等应用程序。为了便于描述，将用户开启的需要进行身份验证的程序称为目标程序。在用户开启目标程序时，本实施例提示用户输入用于识别的指纹，从而依据输入的指纹验证该用户是否为合法用户。同样，为了便于描述，可以将用户输入的指纹称为待识别指纹。
步骤S102：响应用户输入待识别指纹的操作，确定预设指纹库中的各个预留指纹的匹配优先级；其中，所述预设指纹库中保存有用户预留的多个指纹。
在实际应用前，本实施例预先设置有指纹库，指纹库中保存有用户预留的指纹，且指纹为多个。需要说明的是，本实施例应用在利用多指纹对待识别指纹进行验证的场景中，解决的是在多个预留指纹的情况下，如何提高身份验证效率的问题。
用户在看到步骤S101生成的提示信息后，可以在指纹输入区域输入指纹。本实施例响应于用户的输入操作，为预设指纹库中的各个指纹数据，确定匹配优先级，需要说明的是，匹配优先级可以表征用户使用预留指纹的情况。
具体地，为每个预留指纹均确定各自对应的匹配优先级，匹配优先级之间具有高低排序，匹配优先级的高低排序可以表示用户使用预留指纹的优先顺序。匹配优先级越高，则表示用户越常使用该预留指纹。
步骤S103：按照所述匹配优先级的高低排序，依次将所述预留指纹与所述待识别指纹进行匹配，获得身份验证结果。
其中，按照确定出的匹配优先级的高低排序，将预留指纹依次与用户输入的待识别指纹进行匹配。
具体地，在依次匹配的过程中，若某个预留指纹与待识别指纹匹配成功，
则生成表示身份验证成功的验证结果，且结束匹配过程。若预设指纹库中的全部预留指纹均匹配完毕，且不存在与待识别指纹匹配成功的预留指纹，则生成表示身份验证失败的验证结果。
由以上的技术方案可知，本实施例提供的身份验证方法，可以响应于用户开启需要进行身份验证程序的操作，提示用户输入用于身份验证的待识别指纹，且在用户输入待识别指纹数据后，为预设指纹库中的各个预留指纹确定各自的匹配优先级，其中，匹配优先级的高低排序可以表示用户对各个预留指纹的优先使用顺序，从而按照各个匹配优先级的高低排序，将各个预留指纹依次与待识别指纹进行比对，从而获得身份验证的结果。与现有技术相比，本实施例并非随机地将预留指纹与待识别指纹进行比对，而是按照确定出的匹配优先级来确定预留指纹的比对顺序，考虑到了用户对指纹的使用情况，从而提高了使用较少匹配次数便获得身份验证结果的概率，即提高了身份验证效率，用户体验较好。
在实际应用中，预设指纹库中的各个预留指纹均各自绑定有一个变量，变量存储的是预留指纹的匹配次数。匹配次数表示的是在本次身份验证前，预留指纹与用户输入的待识别指纹匹配成功的总次数。需要说明的是，此处的待识别指纹并非上述实施例中步骤S102用户输入的待识别指纹，而是在本实施例执行之前，用户进行身份验证过程中输入的指纹。
在该种场景中，上述实施例中的步骤S102响应用户输入待识别指纹的操作，确定预设指纹库中的各个预留指纹的匹配优先级的具体实现方式可以为下述步骤A1。
步骤A1：响应用户输入待识别指纹的操作，依据各个所述预留指纹的匹配次数的高低排序，生成各个所述预留指纹的匹配优先级。
其中，各个预留指纹的匹配次数之间存在高低排序的内在关系。按照预留指纹的匹配次数之间的高低排序，为每个预留指纹生成各自的匹配优先级。按照生成的匹配优先级，便可确定出预留指纹与待识别指纹数据匹配的优先顺序。
例如，预设指纹库中包含三个预留指纹：预留指纹1、预留指纹2及预留指纹3，分别对应的匹配次数为13次、4次及8次，三个预留指纹的匹配次数之间
高低排序为13、8及4。从而，为三个预留指纹生成的匹配优先级依次为预留指纹1、预留指纹3及预留指纹2，即预留指纹1的匹配优先级最高、其次为预留指纹3，最后为预留指纹2，按照这个顺序，依次与待识别指纹数据进行比对。
在实际应用中，进行某次身份验证时，可能存在这样一种情况：多个预留指纹的匹配次数相同，如预留指纹1及预留指纹2的匹配次数均为8。此时，生成预留指纹的匹配优先级时，需要对匹配优先级进行调整。
具体地，对匹配优先级进行调整的一种方式是，预先记录有各个所述预留指纹最近一次与用户输入的待识别指纹匹配成功的时间点，按照匹配成功的时间点的先后顺序，对相同匹配次数的预留指纹的匹配优先级进行调整。
如图2所示，上述实施例中的步骤S102响应用户输入待识别指纹的操作，依据各个所述预留指纹的匹配次数的高低排序，生成各个所述预留指纹的匹配优先级可以具体包括以下步骤S201～步骤S202。
步骤S201：响应用户输入待识别指纹的操作，依据各个所述预留指纹的匹配次数的高低排序，确定各个所述预留指纹的初始匹配优先级。
其中，首先按照预留指纹匹配次数的排序，确定出初始匹配优先级。例如，三个预留指纹(预留指纹1、预留指纹2及预留指纹3)的匹配次数分别为13、8及8，相应地，三个预留指纹的初始匹配优先级为：预留指纹1的初始匹配优先级最高，预留指纹2及预留指纹3的初始匹配优先级相同且低于预留指纹1，即预留指纹1>预留指纹2＝预留指纹3。
步骤S202：若存在初始匹配优先级相同的情况，按照记录的所述时间点的先后顺序，调整相同的所述初始匹配优先级。
其中，按照匹配次数的高低顺序，确定出初始匹配优先级后，判断初始匹配优先级是否相同，若存在相同的情况，则对相同的初始匹配优先级进行调整。调整的方式，是按照记录的各个预留指纹的最近一次匹配成功的时间点先后顺序。具体地，时间点在先，则升高该时间点对应的预留指纹的初始匹配优先级。
在上一示例中，预留指纹2及预留指纹3的初始匹配优先级相同，但两者最近一次与待识别指纹匹配成功的时间点分别为6月4日11点33分、6月4日11点35分，预留指纹2的时间点在预留指纹3之前，因此，升高预留指纹2的初始匹配优先级，从而最终的匹配优先级为：预留指纹1>预留指纹2>预留指纹3。
由以上的技术方案可知，该种实现方式可以解决预留指纹匹配次数相同的情况下，如何确定匹配优先级的问题。并且，在解决该问题过程中，考虑到用户近期使用各个预留指纹的情况。由于，用户使用指纹的顺序往往是由使用习惯决定的，所以，近期使用预留指纹的顺序，会对本次身份验证中确定匹配优先级进行提示，因此，根据时间点的先后顺序调整后的匹配优先级，可以提高身份验证的效率，用户体验较好。
存在匹配优先级相同的情况下，对匹配优先级进行调整的另一种方式可以是，记录最近一次与用户输入的待识别指纹进行匹配的预留指纹，若该预留指纹正好与其他预留指纹相同，则调整该预留指纹的匹配优先级。
具体地，如图3所示，上述实施例中的步骤S102响应用户输入待识别指纹的操作，依据各个所述预留指纹的匹配次数的高低排序，生成各个所述预留指纹的匹配优先级可以具体包括以下步骤S301～步骤S302。
步骤S301：响应用户输入待识别指纹的操作，依据各个所述预留指纹的匹配次数的高低排序，确定各个所述预留指纹的初始匹配优先级。
其中，首先按照预留指纹匹配次数的排序，确定出初始匹配优先级。例如，三个预留指纹(预留指纹1、预留指纹2及预留指纹3)的匹配次数分别为13次、8次及8次，相应地，三个预留指纹的初始匹配优先级为：预留指纹1的初始匹配优先级最高，预留指纹2及预留指纹3的初始匹配优先级相同且低于预留指纹1，即预留指纹1>预留指纹2＝预留指纹3。
步骤S302：若记录的所述预留指纹与其他预留指纹的初始匹配优先级相同，升高记录的所述预留指纹的初始匹配优先级。
其中，判断记录的最近一次匹配成功的预留指纹的初始匹配优先级是否与其他预留指纹的相同。例如，记录的最近一次匹配成功的预留指纹为预留指纹3，其初始匹配优先级与预留指纹2的相同。
因此，升高记录的该最近一次匹配成功的预留指纹的初始匹配优先级。其中，升高的方式可以是，将记录的该预留指纹的初始匹配优先级升高至相同的预留指纹的前一位，如将预留指纹3的初始匹配优先级升高至预留指纹2的前一位，从而最终的匹配优先级为：预留指纹1>预留指纹3>预留指纹2。或者，升高的方式还可以是，将记录的该预留指纹的初始优先级升高至最高，如将预留
指纹3的初始匹配优先级升高至预留指纹1的前一位，从而最终的匹配优先级为：预留指纹3>预留指纹1>预留指纹2。
由以上的技术方案可知，该种实现方式可以解决预留指纹匹配次数相同的情况下，如何确定匹配优先级的问题。并且，该种实现方式不仅考虑到预留指纹的使用总次数，还考虑到了预留指纹的最近一次使用情况，根据最近一次使用预留指纹的情况，对本次身份验证中的匹配优先级进行调整，可以调高身份验证效率，用户体验更好。
需要说明的是，在实际应用中，还可能存在两个以上预留指纹的匹配次数相同的情况，这样，升高某个预留指纹的初始优先级后，对其他相同的预留指纹再进行排序。排序的方式可以随机，或者，记录有每个预留指纹最近一次匹配成功的时间点，按照最近一次时间点的先后排序，对其他相同的预留指纹进行排序。
为了保存每个预留指纹的匹配次数，在每次身份验证中，若身份验证结果为成功，则将与待识别指纹匹配成功的预留指纹的匹配次数加1，实现对预留指纹的匹配次数的更新。
参照图4，其示出了本申请提供的身份验证方法另一实施例的流程。如图4所示，在上述图1基础上，本实施例还可以包括步骤S104。需要说明的是，图4中的步骤S101至步骤S103可以参照上述图1中的步骤S101至步骤S103，此处并不赘述，以下仅对步骤S104进行说明。
步骤S104：在所述身份验证结果为失败的情况下，显示备选身份验证界面，以使用户在所述备选身份验证界面进行身份验证；其中，所述备选身份验证解密包括密码验证解密或图形验证解密。
其中，在获得身份验证结果后，判断身份验证结果为成功还是失败。若身份验证结果为失败，为了完成身份验证过程，则可以调用备选身份验证模块。具体地，显示备选身份验证界面，如密码验证界面或图形验证界面，以供用户在备选身份验证界面输入待验证的数据，如密码或图形，调用相应的备选身份验证模块，以完成身份验证。
由以上的技术方案可知，本实施例提供的身份验证方法，可以在指纹识别
为失败的情况下，提供给用户其他的备选身份验证方案，以使用户完成身份验证。
