The supervision mechanism comprises a people bank, a public security organization, a judicial organization and other mechanisms with supervision functions. The authority of the supervision organization is to acquire face recognition transaction details, wherein the transaction details comprise client information, transaction types, transaction time, transaction places, face registration time and the like.
The face data analysis party can be a provider of a face recognition related algorithm, and the authority of the face data analysis party is to acquire operation data of face preprocessing, face detection, face feature extraction and face recognition algorithm, analyze and calculate indexes such as detection rate, false detection rate, omission rate and recognition speed of the algorithm, and score the algorithm according to the indexes. And acquiring face pictures and other data, performing model training, and adjusting parameters of a face recognition related algorithm according to a training result, so that various indexes such as detection rate, recognition speed and the like based on a neural network algorithm are further improved.

Step 104, face registration and face recognition processing: and according to the face registration and the face recognition, running a related algorithm to perform face registration and face recognition processing. When registering a face, generating a face retrieval index according to client information, and generating a primary index library or a multi-level index library according to the certificate number abstract, the password abstract, the mobile phone number and the rear 4 bits of the mobile phone number to solve the problem of face index 1: the efficiency of N; recording the results of face registration and face recognition and transaction details.

In this embodiment, the steps of the face registration service are as shown in fig. 5:
the client selects the face recognition service type to be opened (multiple services can be simultaneously selected to be opened) on an APP or PC webpage of the face scene service provider. E.g. selecting to switch on the face payment service on the APP of the bank.
Step 201, a customer starts a camera at a face scene service provider and collects a scene face picture, and real transaction is guaranteed for the customer through living body detection and other means.
Step 202, the client inputs the client information through the page of the face scene service provider or the page provided by the face registration server, wherein the client information comprises a name, a certificate type, a certificate number and a mobile phone number.
In step 203, a scene auxiliary element, that is, the aforementioned business scene information, is an additional transaction element, including but not limited to a transaction bank card number, a payment password, a short message verification code, etc., which is input by the customer according to the specific use scene requirement of the face. The validity of the scene auxiliary elements is verified by the face scene service provider. For example, when a face payment service is opened, a face payment password needs to be input, a bank card number is used as a scene auxiliary element, and a scene provider performs verification of the validity of the card number.
Step 204, invoking the face registration service of the blockchain, firstly checking the transaction signature certificate of the caller, and then reading the authority information uploaded into the blockchain by the authority management server according to the ID previously assigned to the caller, and judging whether the authority of face registration is possessed. If the authority check is passed, an intelligent contract is operated, and face registration is carried out according to algorithms such as contracted face detection, face characteristic value calculation and the like.
In this embodiment, in order to improve the 1:n face retrieval efficiency in face recognition service, a face index library is built according to different scenes. The face index library is used for dividing the face credit library into libraries according to specific elements serving as indexes to form face sub-libraries, so that the retrieval efficiency is improved. Taking the face payment scenario as an example, when a customer makes face payment, a phone number back 4 or a payment password is usually required. Therefore, the last 4 digits of the mobile phone number or the payment password can be used as the face library index. When registering a face, face characteristic information is calculated through a face picture, MD5 abstract operation and salt addition operation are respectively carried out on the last 4 digits of a mobile phone number and a payment password, the operation result is used as an index, and the face characteristic information of the same operation result is put into a face sub-library, so that two index libraries of the last 4 digits of the mobile phone number and the payment password are formed. When the face of the customer pays, the customer is required to input the 4-bit or payment password after the mobile phone number, the face recognition algorithm carries out MD5 abstract operation and salifying operation on the 4-bit or payment password after the mobile phone number, and the face index library where the face characteristic information of the customer is located is determined, so that the searching range of 1:N face searching is greatly reduced, and the searching efficiency is improved.
Step 205, recording the details of the face registration, and returning the registration result to the caller of the face registration service.
Fig. 6 shows the steps of the face recognition process in this embodiment.
In step 301, a customer performs a face recognition related service through a scene provider. For example, at the POS machine, a face payment service is used to conduct the order receiving service.
