Fig. 1 is a flowchart of an identity authentication method according to a first embodiment of the present invention. As shown in fig. 1, the identity authentication method of the present embodiment includes the following steps:
step S110, responding to the identity authentication request of the user, and acquiring the image and the identity information of the user. In an alternative implementation, the portrait photo and the identification card photo of the user are collected by a collecting device (such as a camera, etc.), and the identification information is obtained by analyzing the text information (name, gender, date of birth, etc.) on the identification card photo.
And step S120, responding to the fact that the identity authentication request of the user is not the first authentication, and calculating the similarity between the collected image and the image of the user in the local image library. And when the identity information of the user exists in the local identity information base, judging that the user is not authenticated for the first time.
Step S130, in response to the similarity being greater than the first threshold, determining that the user identity authentication is successful. The first threshold value is adjusted according to the authentication state of the user, and the authentication state of the user comprises an authentication request address and/or an authentication request frequency.
In the embodiment, the similarity between the acquired image of the user and the image of the user in the local image library is acquired, and when the similarity is greater than a first threshold, the user is judged to pass the identity authentication, wherein the first threshold is adjusted according to the authentication state of the user, so that the authentication threshold is improved when the authentication request of the user is abnormal, and the authentication threshold is reduced when the historical authentication record of the user is good, thereby reducing the authentication error rate of the system and improving the safety and reliability of the system.
Fig. 2 is a flowchart of an identity authentication method according to a second embodiment of the present invention. As shown in fig. 2, the identity authentication method of the present embodiment includes the following steps:
step S210, in response to the identity authentication request of the user, acquiring and acquiring an image and identity information of the user. In an alternative implementation, the portrait photo and the identification card photo of the user are collected by a collecting device (such as a camera, etc.), and the identification information is obtained by analyzing the text information (name, gender, date of birth, etc.) on the identification card photo.
Step S220, determine whether the identity authentication request of the user is the first time authentication request. In an optional implementation manner, whether information matching with the identity information of the user exists is searched in a local identity information base, if the information matching with the identity information of the user does not exist, it is determined that the user initiates an authentication request for the first time, and step S230 is executed. If the local identity information base has information matched with the identity information of the user, it is determined that the user does not initiate an authentication request for the first time, and step S260 is executed.
Step S230, when the user initiates an authentication request for the first time, sending the collected image and the identity information of the user to the identity management department for terminal authentication. In an optional implementation manner, an image which is generated based on a collected portrait photo of a user and conforms to the size specified by an identity management department and identity information of the user are sent to an identity management department terminal for authentication.
Step S240, obtaining the authentication result of the terminal of the identity management department. Specifically, the identity management department terminal performs identity authentication on the user according to the image information and the identity information of the user, and returns an authentication result. When the terminal of the identity management department passes the verification, the user identity authentication is judged to be successful, and when the terminal of the identity management department does not pass the verification, the user identity authentication is judged to be failed.
Step S250, in response to the user identity authentication being successful, binding the acquired image of the user with the identity information, storing the acquired image of the user in a local image library, and storing the identity information of the user in a local identity information library.
Step S260, when the user does not initiate the authentication request for the first time, calculating the similarity between the acquired image of the user and the image stored in the local image library. In an optional implementation manner, the corresponding identity information is queried in the local identity information base according to the identity information of the user, and then the image in the local image base bound with the identity information is searched according to the identity information in the local identity image base.
Step S270, in response to the similarity being greater than the first threshold, determining that the user identity authentication is successful. The first threshold value is adjusted according to the authentication state of the user, and the authentication state of the user comprises an authentication request address and/or an authentication request frequency. Therefore, the authentication threshold can be improved when the identity authentication request of the user is abnormal, and the authentication threshold can be reduced when the historical authentication record of the user is good, so that the authentication error rate of the system can be reduced, and the safety and the reliability of the system can be improved.
Optionally, when the user performs the first identity authentication, the identity information of the user includes the text information (name, gender, birth date, household registration, etc.) and the information of the user name, the contact information, etc. on the analyzed identity card photo, and when the user does not perform the first identity authentication, the identity information of the user may only include one of the text information, the user name, the contact information, etc. on the analyzed identity card photo.
In an optional implementation manner, the identity authentication method of this embodiment further includes the steps of:
and adding the user into a white list or a black list according to a preset rule based on the authentication state of the user. For example, a user with a good history of authentication (e.g., successfully authenticated each time identity authentication is performed substantially once) is added to the white list, and a user with a high authentication request frequency, or with a continuous number of real requests, or with an unfamiliar authentication request address is added to the black list.
Further, the identity authentication method of the embodiment further includes the steps of:
the first threshold is adjusted to a first value in response to the user being on the white list. Adjusting the first threshold to a second value in response to the user being on a blacklist. Wherein the second value is greater than the first value. Therefore, the authentication threshold can be improved when the identity authentication request of the user is abnormal, and the authentication threshold can be reduced when the historical authentication record of the user is good, so that the authentication error rate of the system is reduced, and the safety and the reliability of the system are improved.
In another optional implementation manner, the identity authentication method of this embodiment further includes the steps of:
the first threshold is increased in response to the user's consecutive authentication requests and/or the user's authentication request address being a strange address. In this embodiment, the first threshold may be dynamically adjusted according to the authentication state of the user, so as to further improve the system applicability. For example, when the user makes an authentication request with a strange address for the first time, the first threshold value is adjusted to the third value. And when the user frequently carries out authentication requests by adopting the unfamiliar address for multiple times, adjusting the first threshold value to be a fourth value. Wherein the third value is greater than the first value and the third value is less than the fourth value.
In an optional implementation manner, the identity authentication method of this embodiment further includes the steps of:
and responding to the successful user identity authentication, and storing the acquired image of the user into a local image library. Thus, the local image library includes a plurality of images of the user.
Further, the identity authentication method of the embodiment further includes the steps of:
and when the identity authentication request of the user is not the first authentication, calculating the similarity between the acquired image of the user and the images of the users in the local image library respectively. Optionally, a predetermined image of the user in the local image library is randomly selected.
And in response to the at least one similarity being larger than the first threshold, determining that the user identity authentication is successful. That is to say, the similarity between the acquired image of the user and the images of the users in the local image library is compared with a first threshold, and as long as the similarity between the acquired image of the user and the image of one user in the local image library is greater than the first threshold, the user identity authentication is determined to be successful. Therefore, the problem of identity authentication failure caused by the problem of the angle or the definition of the acquired image can be avoided, the false rejection rate is further reduced, the situation that the user repeatedly acquires the image for multiple times is avoided, and the reliability and the practicability of the system are improved. Where false rejects are used to characterize that authentication should actually succeed and the system displays that authentication failed.
In an optional implementation manner, the identity authentication method of this embodiment further includes the steps of:
and responding to the fault of the local image authentication engine, and sending the acquired image and identity information of the user to an identity management department terminal for authentication. And receiving the authentication result of the terminal of the identity management department, responding to the passing of the terminal authentication of the identity management department, and judging that the user identity authentication is successful. Therefore, the embodiment adopts two engines for identity authentication, and further improves the reliability and the practicability of the system.
In an optional implementation manner, the identity authentication method of this embodiment further includes:
the local image authentication engine and the management authentication engine check each other periodically to ensure the authentication accuracy of the local image authentication engine and the management authentication engine. The local image authentication engine is used for performing identity authentication according to the local image library and the local identity information library. The management department authentication engine is connected with the identity management department terminal and used for sending the collected image information and the identity information and receiving the authentication result of the identity management department. Specifically, a plurality of positive samples and a plurality of negative samples are obtained. The positive sample is the user image information and the identity information which are matched with each other, and the negative sample is the user image information and the identity information which are not matched with each other. And respectively adopting a local image authentication engine and a management department engine to perform identity authentication on the positive sample and the negative sample, and if the identity authentication results of the two authentication engines are the same and are consistent with the actual condition, enabling the two authentication engines to be in a complete state currently. If the identity authentication results of the two authentication engines are different or are not matched with the actual situation, at least one authentication engine has a fault. Therefore, the authentication engine is checked regularly, so that the authentication accuracy of the authentication engine is ensured, and the reliability of the system is further improved.
