Implementation of Personal Information Security Protection Technology Based on Block Chain

The decentralization and intelligence of block chain technology are consistent with the concept of personal information protection. The industry generally believes that its application in personal information protection will effectively support the development of multiple types of personal information systems and the extensive participation of multiple users. This paper analyzes the application of personal information protection to block chain application based on the actual technical requirements and application requirements of personal information protection. Aiming at the problems of information security such as loss of private key and disclosure of privacy, the corresponding countermeasures are proposed. Finally, this paper interprets the application of current block chain in personal information protection.
