Safe, efficient and universal method for proving original value of electronic document

Abstract

The invention discloses a safe, efficient and universal method for proving an original value of an electronic document. On the basis of establishment of a proof service system which consists of a server and a client, a user performs registration and login through the client, and the proof service of the electronic document can be performed. The method comprises the processes of registration, validation and system reliability validation. In the process of registration, the user submits a Hash value a of the electronic document to the server through the client; and the server generates an electronic document registration certificate and then sends the electronic document registration certificate to the client. In the process of validation, the server calculates the Hash value of different levels, compares the Hash value with the Hash value which is originally registered to draw a conclusion on correction or non-correction of a file, and then sends the conclusion to the client. In the process of system reliability validation, a supervisory validation result certificate is generated, and returned to a supervisory mechanism. The method has the advantages that: the conclusion is high in creditability; the reliability of the proof service system can be proved by using a certain method; and the authority of the conclusion is ensured.

Description

technical field [0001] The present invention relates to the field of data security in computer science and information security discipline, and in particular to a method for proving the originality of electronic data documents often faced by computer forensics and electronic text forensics, that is, to prove whether electronic documents have been tampered with. This method is universal and suitable for electronic data files in all industries.
