Block chain token login method

Abstract

The invention discloses a block chain token login method. The method comprises the following steps: S1, firstly, making and uploading a public key to a block chain; s2, calculating a private key through an RSA algorithm; s3, generating different private keys through the public key by using an RSA algorithm; distributing and storing the private key into different hardware devices (such as an intelligent id card); and S4, if a user wants to log in the bank account checking system, only when the hardware verification is passed and the face system verification is passed, the user can log in the bank account checking system after double verification. The method has the following advantages: 1, for the security problem, external hardware and face recognition are combined for permission login, so that the security is greatly improved, and the possibility of network virus or illegal software hijacking is eliminated; 2, since external software performs matching key login according to an algorithm, waste bandwidth and CPU performance do not need to be considered at all; and 3, if attacked, the public key cannot be destroyed or changed.

Description

technical field [0001] The invention relates to the field of blockchain token login, in particular to a blockchain token login method. Background technique [0002] The existing technology is: encrypted token Token login [0003] The main principles are as follows: [0004] The client uses the user name and password to request to log in to the server. After receiving the request to verify the user name and password, the server will issue a Token, and then send the Token to the client. After receiving the Token, the client can store it For example, each time the client requests resources from the server in localStorage, the client needs to bring the Token issued by the server to receive the request, and then verify the Token carried in the client request. If the verification is successful, it will be released. . (In short, it is the key (token) to pass through the server with the username and password, as long as you have the key, you can log in). [0005] shortcoming: ...

AI Technical Summary

Problems solved by technology

[0008] 2. If you cannot log out on the server side, it is difficult to solve the hijacking problem. If the token is illegally hijacked by a virus or an external algorithm, it will be easily cracked and logged in

[0009] 3. Performance issues

For web applications with strict performance requirements, this is not ideal, especially for single-threaded environments

At present, there is no instance of using blockchain features to control login
