Unified account information management method based on biological characteristic encryption

Abstract

The invention discloses a unified account information management method based on biological characteristic encryption. The management method particularly includes the steps: 1 acquiring user account information; 2 performing crypto-binding on biologic characteristic information and secret keys by the aid of a fuzzy vault algorithm; 3 encrypting plain text files of the account information by the aid of a symmetric encryption algorithm; 4 generating encryption data and auxiliary information; 5 logging user accounts. According to the management method, user fingerprint characteristics and user secret keys are bound by the aid of fuzzy vault technology, the user secret keys and fingerprint security are greatly protected, the plain text files of the account information are encrypted by the aid of the symmetric encryption algorithm, and the security of the user account information is effectively ensured by the aid of a dual-protection mechanism. By the management method, user account information is integrally managed, and user convenience is achieved while security of the account information is ensured.

Description

technical field [0001] The invention belongs to the technical field of computer security, and in particular relates to a biological feature encryption and account information management method, which can be used for integrated management of user account information and protect user account information security. Background technique [0002] In recent years, with the rapid development of today's Internet, in order to meet the needs of users in various aspects, various computer-side applications emerge in an endless stream. Each user often registers many applications according to his own needs and preferences. Common computer applications mainly include: e-mail, online banking, chat software, shopping websites, etc. The ensuing problem is that users need to accurately remember the account name and password of each application, which makes account management and memory very inconvenient. Moreover, mistakes in password entry often occur, account names and passwords are mixed, f...
