The embodiment of the invention discloses a document authentication traceability method and device, and aims at tracing a document modification record and personnel information for executing the modification record through a block chain so as to ensure the reliability of the document modification record and the personnel information for executing the modification record. The method provided by theembodiment of the invention comprises the steps of receiving a tracing request of a document; querying a modification record description block and a first authentication identifier of the document from a local data table according to the tracing request, the modification record description block recording design parameters and modification records of the document, a user description block and a second authentication identifier code, and the first authentication identifier being an identifier code of the modification record description block in the blockchain system; calculating a hash abstract of the modification record description block; sending a modification record authentication request to the blockchain system according to the hash abstract of the modification record description block and the first authentication identifier; and receiving a modification record authentication result sent by the blockchain system.
Description
technical field [0001] The present application relates to the technical field of computer data processing, in particular to a document authentication and traceability method and device. Background technique [0002] Design documents (drawings of product design), as a kind of creative contribution of staff, embody the creative achievements of designers. In the prior art, when the source of design documents is traced, it is generally through user-associated data when users upload design documents To trace the source of the design, this may lead to the fact that the associated information stored in the database can actually be tampered with. [0003] Furthermore, the design tracking of materials derived from drawings and BOM (Bill of Design) is also deduced from associated data. This association is very fragile and easy to be tampered with. Contents of the invention [0004] The embodiment of the present application provides a document authentication and traceability method ...
