Registration and authorization method device and system

An authorization method applied to an access server which is a node in a blockchain network, the method comprising:

• receiving an access request message sent by a user device, wherein the access request message includes user identity information;
• inquiring identification information and authorization information of the user in the blockchain according to the user identity information through the access server;
• performing identity verification on the user according to the identification information;
• and
• allowing the user to access the designated service according to the authorization information after the verification is passed,
• wherein the identification information is a user public key, and performing identity verification on the user according to the identification information comprises:
• sending instruction information instructing the user to provide identification to the user device;
• receiving signature information of the user private key signature sent by the user device according to the instruction information;
• and
• performing signature verification on the signature information according to the user public key, and determining that the identity verification is passed if the signature verification succeeds.

An authorization server, wherein the authorization server is a node in a blockchain network and stores a blockchain composed of a plurality of blocks, each block is used for storing authorization information, and the authorization server comprises:

• a processor, a communication interface, a memory and a communication bus;
• the processor, the communication interface and the memory communicate with each other through the communication bus;
• the memory is used for storing application programs;
• the processor is used for performing the application program to implement the following method:
• receiving a registration request message sent by a user device, wherein the registration request message includes identification information, and the identification information is used for performing identity verification on a user;
• assigning authorization information to the user, wherein the authorization information is used to indicate a service that the user can access;
• and
• writing the identification information and the authorization information into the blocks of the blockchain through the authorization server.
