Multi-stage electronic file record generating and checking method

Abstract

The invention provides a multi-stage electronic file record generating and checking method, which comprises the following steps that A, a current record template used for generating the current stage of the electronic file record is determined, and the record template records the record attribute contents to be signed in the current time; B, record attribute contents in the selected record template in the current time are added into a record attribute region of the electronic file record; the current record template is signed, and the generated current record signature is added to a record signature region; C, the record attribute contents of each time recorded in the record attribute region of the electronic file record are subjected to integral signature, and the generated current integral signature is used for updating the generated integral signature generated by the last time of electronic file record recorded in the record signature region. Correspondingly, the invention also provides a multi-stage electronic file record verification method. Through the multi-stage record attribute, so that the electronic file adopts different bodies for ensuring the evidence performance by aiming at different metadata information in different stages.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for generating and verifying multi-level electronic document certificates. Background technique [0002] In the current electronic file management system, in addition to managing the physical file of the electronic file itself, it is also necessary to manage the metadata information owned by the electronic file. The metadata is a record of the authenticity of the entire process of document generation, storage, utilization, and destruction. It is generated along with the production of documents and continuously increases with people's various management activities on documents. In order to ensure the authenticity of electronic documents, an electronic document certificate will be generated for each electronic document. [0003] The current common practice is to use signature technology to generate electronic document certificates for electronic documents the...

Problems solved by technology

However, the existing technology for generating electronic document vouchers is not flexible enough. The specific performance is as follows: firstly, different systems will formulate different voucher generation rules, so they cannot verify each other; The authenticity of the document; finally, since the metadata information of the electronic document will change during the electronic document management process, the signing entities for the same metadata may be different
