Electronic data security system and method based on mobile terminal

Abstract

The invention discloses an electronic data security system and method based on a mobile terminal, the system comprises a server and a client, the client is arranged on the mobile terminal, and the client comprises an identity authentication module and a password security module; the server comprises a data preservation module; the server carries out local encryption storage on the security electronic data original text, the original text hash value, the digital signature information and the identity authentication information; meanwhile, the hash value of the preserved electronic data and the summary data are uploaded to a third-party judicial evidence storage mechanism for evidence storage; and when authentication is needed, a hash value of the preserved electronic data original text which is locally encrypted and stored is calculated, the hash value and a hash value stored by a third-party judicial evidence storage mechanism are checked and whether the data is tampered or not is judged. Legality and authority of the preserved electronic data can be ensured, and fair electronic evidence with legal efficacy can be obtained.

Description

technical field [0001] The invention relates to the technical field of data protection, in particular to a mobile terminal-based electronic data protection system and method.

Problems solved by technology

Court preservation and impartial preservation have disadvantages such as low efficiency, high cost, and lack of necessary technology

As a product of the development of the information society, third-party data security platforms can give full play to their unique advantages and overcome the shortcomings of traditional court security and impartial security. However, third-party data security platforms are generally developed by application system manufacturers and lack necessary password security protection methods. There are certain security means, which are also implemented through software, not through special hardware encryption equipment, and there are disadvantages such as closed technology, low social recognition, lack of theoretical research, and lack of judicial certification.
