Abstract

The invention discloses an identity authorization method and system based on a block chain, and relates to the technical field of computers. The method comprises the following steps: a user side obtains a session identifier of a service system; the user side generates a first signature of the current user based on the private key and the session identifier of the current user; sending the first signature, the identity information of the current user, the session identifier and the public key of the current user to a service system; the service system verifies whether the first signature is legal or not according to the session identifier and the public key of the current user, if yes, a second signature of the current user is obtained from the block chain, whether the second signature of the current user is legal or not is verified according to the identity information of the current user and the public key of the authentication system, and if yes, it is determined that authorization of the current user is passed; wherein the block chain stores the second signature of the user passing verification of the authentication system, and the second signature of the user is determined by the identity information of the user and the private key of the authentication system. According to the embodiment, the identity authorization process can be simplified, and the identity authorization efficiency is improved.

Description

technical field [0001] The invention relates to the field of computer technology, and in particular, to a method and system for identity authorization based on blockchain. Background technique [0002] In order to ensure data security, the business system usually needs to verify the identity of the access user to verify whether the user has the corresponding access authority. [0003] In the prior art, the business system needs to call the authentication system for each authorization process. Taking SMS verification as an example, the user accesses the server of the business system through the client of the business system. The server of the business system will generate a verification code based on the user's mobile phone number, and call the interface of the SMS operator to send the verification code to the mobile phone number. The user inputs the verification code on the client of the business system, the client of the business system sends the verification code to the s...
