Abstract

The invention relates to a cloud terminal identity authentication method based on blockchain encryption and biological information identification. The method comprises the steps of identity information authentication file issuing and identity information authentication login; identity information authentication file issuing comprises the steps of acquiring related information of an identity authentication applicant; encrypting the related information based on a blockchain elliptical encryption algorithm to generate an identity information authentication file, storing the identity information authentication file in a distributed storage system in a slicing manner, and storing the identity information authentication file in an identity authentication information storage medium at the same time; and issuing the identity information authentication file to an identity authentication applicant; the identity information authentication login comprises the following steps of enabling a cloud server to determine a user identity according to an identity information authentication file in an identity authentication information storage medium; and recording identity information authentication login operation and updating the identity information authentication file through the distributed storage system. According to the invention, all-round protection of user data security can be realized,and the possibility of cracking is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a cloud terminal identity authentication method based on block chain encryption and biological information identification. Background technique [0002] Identity authentication for cloud terminal (cloud desktop) login is one of the important means to protect the information and property security of cloud terminal service providers and users. From a practical point of view, a strong and effective identity authentication method can enable the cloud terminal access policy to be executed reliably and effectively, prevent attackers from impersonating legitimate users to obtain access to resources, ensure the security of the system and data, and the security of authorized visitors. legitimate interests. [0003] In the existing technology, there are three basic methods for user identity authentication: the first is identity authentication based on information ...
