The specific application scene of the application is that a teller logs in a corresponding matched service system by inputting a password to transact related services for clients. FIG. 1 is a schematic diagram of a matching relationship between a teller and a service system according to the present application, as shown in FIG. 1, the functions of the service systems used by teller with different levels and different services are not necessarily the same, and the same teller may also use a plurality of different service systems, more specifically, for example, teller user_1 may only log into service system sys_1 and corresponding login password pass_1_1; the teller user_2 can log in the service system sys_1, the corresponding login password pass_2_1, the teller user_2 can log in the service system sys_2, the corresponding login password pass_2_2, the teller user_2 can log in the service system sys_3 and the corresponding login password pass_2_3; the teller user_3 can log in the service system sys_1, the corresponding login password pass_3_1, the teller user_3 can log in the service system sys_3, the corresponding login password pass_3_3, the teller logs in the corresponding system according to banking business which is transacted by a customer as required, for example, the teller user_3 logs in the service system sys_1 according to the business task_1 transacted by the customer, and the teller user user_3 logs in the service system sys_3 according to the business task_2 transacted by the customer.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a flowchart of a terminal function operation method according to an embodiment of the present application, and as shown in fig. 2, the terminal function operation method according to the embodiment includes the following steps:

Step S101, acquiring first identification information, where the first identification information characterizes fingerprint features of a user.

The first identification information is, for example, fingerprint information of a user logging into the service system, i.e. the target terminal device is provided with a fingerprint acquisition unit, through which fingerprint information of a teller can be obtained. In a possible implementation manner, referring to the schematic diagram of the matching relationship shown in fig. 1, the target terminal device collects fingerprint information of the teller user_1, the teller user_2 and the teller user_3 through the fingerprint collecting unit, so that the service systems of the corresponding teller can be respectively logged in. Further, the target terminal device collects fingerprint information of different fingers of the teller user_2 through the fingerprint collecting unit, and can log in different corresponding service systems sys_1, sys_2 and sys_3.

Step S102, verifying the first identification information according to first teller data preset in the target terminal equipment to obtain a first verification result, wherein the first teller data is used for representing fingerprint characteristics of a user with operation authority on the target terminal equipment.

The first teller data is fingerprint verification information for verifying the fingerprint information collected by the fingerprint collection unit, that is, the first identification information is verified by the first teller data, so as to obtain a first verification result. More specifically, for example, the first teller data is preset data, and when the authority personnel opens the authority of the related service to the teller, the fingerprint information of the teller is collected by the fingerprint collection unit, set as the first teller data, and preset and stored in the target terminal device; and when the client transacts the corresponding service, the target terminal equipment acquires the fingerprint information of the teller through the fingerprint acquisition unit and verifies with the preset first teller data, if the verification is successful, a first verification result is obtained, the subsequent login verification operation is executed according to the first verification result, and if the verification fails, the fingerprint information of the teller needs to be acquired again and verified again.

In one possible implementation manner, the reliability of the first verification result is related to the collected fingerprint area, that is, the collected fingerprint area may be used as one of the reference bases for determining the reliability of the first verification result, fig. 3 is one of the specific implementation step diagrams of step S102 in the embodiment shown in fig. 2, and as shown in fig. 3, the specific implementation steps of step S102 include:

step S1021, determining a fingerprint collection area according to the first identification information, wherein the fingerprint collection area characterizes the size of the area where the fingerprint collection unit collects the fingerprint.

Step S1022, determining a first verification result according to the first identification information, the first teller data and the fingerprint collection area.

The fingerprint collection area is exemplified by the size of the area where the fingerprint collection unit collects the fingerprint, that is, the fingerprint collection unit collects the fingerprint information of the teller, and determines the area value corresponding to the collected fingerprint information at the same time, and by analyzing the fingerprint verification information of the first teller data, the area value corresponding to the fingerprint verification information can be determined, so that the first verification result can be determined according to the first identification information, the first teller data, the area value corresponding to the collected fingerprint information and the area value corresponding to the fingerprint verification information, and the credibility of the first verification result can be obtained. More specifically, for example, the collected fingerprint information info_1 and the collected fingerprint information info_2 are verified according to the preset fingerprint verification information, respectively, under the same condition, if the area value corresponding to the collected fingerprint information info_1 is 15 and the area value corresponding to the fingerprint verification information is 20 as the standard value, the ratio of the two is 0.75, if the area value corresponding to the collected fingerprint information info_2 is 18, the ratio of the area value corresponding to the collected fingerprint information to the area value corresponding to the fingerprint verification information is 0.9, and further, the reliability of the first verification result res_2 corresponding to the collected fingerprint information info_2 is greater than the reliability of the first verification result res_1 corresponding to the collected fingerprint information info_1 can be determined according to the reliability relationship.

In the step of this embodiment, by introducing the fingerprint collection area as one of the bases for ensuring the credibility of the first verification result, that is, under the same condition, the larger the area corresponding to the collected fingerprint information is, the larger the credibility of the first verification result obtained by verifying the collected fingerprint information according to the fingerprint verification information is, so that the security of the service system can be improved.

In another possible implementation manner, according to the security level of the service system, the teller should log in the service system at least once for fingerprint verification, that is, the first identification information includes at least one third identification information, fig. 4 is a second schematic diagram of a specific implementation step of step S102 in the embodiment shown in fig. 2, and as shown in fig. 4, the specific implementation steps of step S102 include:

step S102a, verifying at least one third identification information according to first teller data preset in the target terminal equipment to obtain at least one second verification result.

Step S102b, obtaining a first verification result according to at least one second verification result and a corresponding preset weighting coefficient.

For example, according to the security level of the service system, when the teller logs in the service system for one time, the first identification information includes a third identification information, that is, the first identification information includes a collected fingerprint information info_1, according to the preset fingerprint verification information, the collected fingerprint information info_1 is verified to obtain a second verification result res_sec_1, and because only one collected fingerprint information in the first identification information is preset, the weighting coefficient is num_1, and then according to the weighted average method, the first verification result res_1 is obtained.

For example, according to the security level of the service system, the teller logs in to the service system at least twice, more specifically, for example, the verification times are three times, the first identification information includes three pieces of third identification information, that is, the first identification information includes collected fingerprint information info_1, collected fingerprint information info_2 and collected fingerprint information info_3, according to preset fingerprint verification information, where the preset fingerprint verification information may be fingerprint verification information of the same finger or fingerprint verification information of different fingers, and further verifies the three collected fingerprint information to obtain second verification results, that is, res_sec_1, res_sec_2 and res_sec_3, and the corresponding preset weighting coefficients are num_1, num_2 and num_3, and further, as shown in formula (1), the first verification result, that is, res_1 is obtained by calculating by a weighted average method is obtained.

In the steps of this embodiment, by introducing the method of multiple verification and weighted average method to determine the first verification result, the security of the service system can be improved, more specifically, according to the security level of the service system, by introducing the method of verification times, successful login of the service system by a single teller can be achieved, and also, login of the service system by simultaneous verification of multiple teller can be achieved, for example, three teller correspond to one fingerprint verification respectively, and three fingerprint verifications are performed in total to achieve login of the service system.

Step S103, according to the first verification result, second teller data is obtained from an authorization server corresponding to the target terminal equipment, and the second teller data represents iris characteristics of a user with operation authority on the target terminal equipment.

The second teller data is iris verification data of a user having operation authority to the target terminal device, and according to the security level of the service system, when the first identification information is verified according to the first teller data to obtain a first verification result, a second verification, namely iris recognition verification, is performed to log in the service system. More specifically, when the first identification information is verified according to the first teller data to obtain a first verification result, a teller number is obtained, and according to the teller number, second teller data matched with the teller number, namely iris verification data, is obtained from an authorization server corresponding to the target terminal device.

In a possible implementation manner, because the data size of the iris data is huge, the time required for transmitting the iris data from the authorization server to the target terminal device is long, so that the required data size of the iris data can be determined according to the first verification result, and further, the second teller data is obtained, fig. 5 is a schematic diagram of a specific implementation step of step S103 in the embodiment shown in fig. 2, and as shown in fig. 5, the specific implementation step of step S103 includes:

Step S1031, obtaining corresponding iris characteristic information according to the confidence coefficient, wherein the iris characteristic information characterizes the characteristic scale of the iris characteristic corresponding to the second teller data.

Step S1032, obtaining the corresponding second teller data from the authorization server according to the iris characteristic information.

Illustratively, the confidence rate characterizes the similarity of the fingerprint feature corresponding to the first identification information and the fingerprint feature corresponding to the first teller data, and the greater the confidence rate, the higher the similarity of the fingerprint feature corresponding to the first identification information (collected fingerprint information) and the fingerprint feature corresponding to the first teller data (fingerprint verification information) is proved. More specifically, for example, when the fingerprint collection unit collects the fingerprint of the teller, if the finger of the teller is dry and clean, the collected fingerprint information is verified according to the fingerprint verification information, and the obtained confidence is 99%, that is, the similarity between the collected fingerprint information and the fingerprint verification information is 99%; if the degree of cleanliness of the finger of the teller is low or the finger is wet, the collected fingerprint information is verified according to the fingerprint verification information, and the obtained confidence coefficient is 95%, namely the similarity of the collected fingerprint information and the fingerprint verification information is 95%.

The iris characteristic information is an iris characteristic data amount corresponding to the iris data, the corresponding iris characteristic data amount is determined through the confidence coefficient, and then the corresponding second teller data can be determined according to the iris characteristic data amount. More specifically, for example, 100 of the total data amount of iris data corresponding to a teller logged into the service system, the corresponding iris feature data amount, that is, the number of iris data of a corresponding proportion is extracted from the total data amount, may be determined according to the confidence obtained by verifying the fingerprint information, and then the second teller data, that is, the iris verification data, is determined according to the iris feature data amount. In one possible implementation manner, when the fingerprint acquisition unit acquires the fingerprints of the teller, if the fingers of the teller are dry and clean, and the corresponding determined confidence coefficient is 99%, determining iris characteristic information, namely an iris characteristic data quantity char_1, according to the 99% confidence coefficient, and further obtaining iris verification data according to the iris characteristic data quantity char_1; when the fingerprint acquisition unit acquires fingerprints of a teller, if the finger cleanliness of the teller is low or the finger is wet, the corresponding determined confidence coefficient is 95%, the iris characteristic data quantity char_2 is determined according to the 95% confidence coefficient, and further iris verification data is obtained according to the iris characteristic data quantity char_2, wherein the iris characteristic data quantity char_1 is smaller than the iris characteristic data quantity char_2. More generally, the higher the confidence, the less data is required to correspond to the desired iris feature data.

In one possible implementation manner, fig. 6 is a schematic diagram of specific implementation steps of step S1032 in the embodiment shown in fig. 5, where, as shown in fig. 6, the specific implementation steps of step S1032 include:

step S10321, determining a first resolution according to the iris characteristic information, wherein the first resolution characterizes the resolution of the iris image.

Step S13022, based on the first resolution, transmits a data request to the authorization server to obtain an iris image having a target resolution matching the iris feature information.

The second teller data includes an iris image, that is, the iris verification data includes an iris image, and when the image information is compared, the resolution of the image needs to be ensured, and the corresponding iris feature data amount is determined through the confidence coefficient, so that the corresponding first resolution, that is, the resolution of the iris image is determined, and the iris image, that is, the second teller data, that is, the iris verification data is acquired according to the determined first resolution. More specifically, for example, the iris feature data amount char_1 is determined from the confidence of 99%, the iris feature data amount char_2 is determined from the confidence of 95%, the resolution reso_1 of the iris image is determined from the iris feature data amount char_1, and the resolution reso_2 of the iris image is determined from the iris feature data amount char_2. Because the higher the resolution of the image is, the larger the corresponding data volume is, and the resolution of the iris image, the request for data is sent to the authorization server according to the resolution of the iris image, wherein the resolution of the iris image, the request for data, is obtained according to the fact that the iris characteristic data volume, the char_1, is smaller than the iris characteristic data volume, char_2, and respectively obtaining iris verification data homomo_1 and iris verification data homomo_2 of target resolution matched with the iris characteristic information, wherein the data volume of the iris verification data homomo_1 is smaller than that of the iris verification data homomo_2.

In the step of this embodiment, because the data volume of the iris verification data is huge, the time required for transmitting the iris verification data from the authorization server to the target terminal device is long, and the occupied network transmission resources are large, so that the confidence coefficient obtained by verifying the collected fingerprint information according to the fingerprint verification information is used as the pre-verification step, the iris characteristic data volume is determined based on the magnitude of the confidence coefficient, the data volume of the iris verification data can be determined according to the corresponding iris characteristic data volume, and further, in order to reduce the duration of transmitting the iris verification data from the authorization server to the target terminal device, the iris characteristic data volume can be determined according to the confidence coefficient in the pre-verification step, and the corresponding data volume of the iris verification data can be reduced, wherein the increasing and decreasing relation between the confidence coefficient and the iris characteristic data volume can be adjusted according to the security level of the service system.

Step S104, second identification information is obtained, verification is carried out on the second identification information based on second teller data, and after verification is passed, the target function is executed, wherein the second identification information characterizes iris characteristics of the user.

The second identifying information is, for example, iris data collected by the target terminal device for the teller through the image collecting unit, the collected iris data is verified according to second teller data obtained from the authorization server, namely, iris verification data, and after verification is passed, a target function is executed, namely, a service system of the target terminal device corresponding to the teller number is logged in. More specifically, for example, fig. 7 is an application scenario diagram of a terminal function operation method provided by the embodiment of the present application, as shown in fig. 7, a target terminal device acquires fingerprint information of a teller through a fingerprint acquisition unit, verifies the acquired fingerprint information according to preset fingerprint verification information to obtain a first verification result, that is, a confidence coefficient, further determines an iris feature data amount according to the confidence coefficient, sends a data request to an authorization server based on the iris feature data amount to obtain corresponding second teller data, that is, iris verification data, verifies iris data acquired by an image acquisition unit according to the iris verification data, and after verification passes, can execute a target function and log in a corresponding service system.

In one possible implementation manner, fig. 8 is a schematic diagram of steps in the implementation of step S104 in the embodiment shown in fig. 2, and as shown in fig. 8, the steps in the implementation of step S104 include:

step S1041, determining a second resolution according to the first verification result, where the second resolution characterizes the image resolution of the face image acquired by the image acquisition unit.

In step S1042, the image acquisition unit acquires an image based on the second resolution to obtain a target face image.

The second resolution is an image resolution of a face image acquired by the target terminal device through the image acquisition unit, the larger the image resolution is, the more pixels of the image are, the more accurate the image verification result is, however, the more pixels of the image are, the more data volume of the corresponding image is, and therefore, the longer the time period consumed for data processing and comparison verification is.

More specifically, the target face image collected by the image collecting unit comprises face outline data, facial five-sense organ data and iris data, and the characteristic recognition is carried out on the target face image according to the verification rule of the login service system, so that collected iris data is obtained.

In the step of this embodiment, the number of pixels of the target face image to be acquired is determined according to the second resolution obtained by the first verification result, so that the target face images with different data amounts are obtained according to the second resolution, and further, if the data amount of the target face image is lower, the image processing speed can be improved when the feature recognition is performed to obtain the second recognition information.

step S201, a fingerprint image is acquired.

Step S202, finger action information is obtained according to the fingerprint image, wherein the finger action information characterizes the pressing characteristics of the finger when the fingerprint image information is obtained.

Further, according to the pressing sequence from the sub-image image_3_1 to the sub-image image_3_2, finger action information of the teller when the fingerprint collection unit collects the fingerprint of the teller can be determined, namely, the finger pressing action is that three sub-area combinations of ABC are pressed first and then three sub-area combinations of BCE are pressed.

Step S203, determining first identification information according to the finger motion information.

Illustratively, the fingerprint of the teller is collected by the fingerprint collection unit, the finger action information is determined, and then the first identification information, namely the collected fingerprint information, is obtained according to the finger action information. More specifically, for example, from the fingerprint of the teller collected by the fingerprint collection unit, finger motion information is determined, such as determining the order of collecting the fingerprints: the finger pressing action is to press three sub-region combinations of ABC first and then press three sub-region combinations of BCE first, and then the collected fingerprint information is determined according to the sequence before and after the collected fingerprints.

In the step of the embodiment, on the basis of acquiring the fingerprint image of the teller, the fingerprint information of the teller is specifically determined by introducing the finger action information, such as the sequence before and after the collection of the fingerprints and/or the number of pressing times of the fingers, namely, the collected fingerprint information is determined according to the fingerprint image and the finger action information at the same time, so that the safety of the service system is ensured.
