Problems solved by technology

[0002] Technical documents refer to the research and development documents that need to be used in the development, or the customer documents for customers. Since the technical documents contain many technical details related to the core design of the product, once the technical documents are leaked to the market in advance, there will be It will bring huge losses to the technical documentation provider
However, the existing technical documents have not been processed before being uploaded to the procurement management system, so if the technical documents are leaked, it is difficult to trace the leaker

specific Embodiment

[0140] In order to facilitate the understanding of the issuing process and traceability process of technical documents, the present invention also provides a specific embodiment, as follows:

[0141] A supplier user logs in to the website of the procurement management system to view the sourcing information released by a company, which contains technical documents, and the supplier requests to download the technical documents.

[0142] The supplier needs to fill in the SMS verification code received on the mobile phone in the front-end page of the procurement management system website, and the background will verify the SMS verification code. If the verification is passed, the digital watermark server will send its mobile phone number, verification code, website login user name and time stamp combined into a character string to form a first digital signature. If the verification fails, it will return the verification failed message, please try again.

[0143] The digital wate...

Abstract

The invention discloses a technical document processing method, a digital watermark server and a processing system. A technical document downloading request is obtained, a corresponding original technical document is obtained according to a unique identifier of the technical document, a corresponding digital signature is generated according to related information of a downloading user, and a corresponding digital watermark is generated based on the digital signature. A target technical document is obtained by embedding a digital watermark into an original technical document, and preset related information of the original technical document and the digital watermark are stored in a block chain system in a corresponding relation mode while the target technical document is sent to a downloading request end for downloading. Because the digital watermark contains the related information of the downloading user, the private data of the downloading user can be effectively protected by storing the digital watermark into the block chain system, when a leaked technical document is found, the digital watermark can be extracted from the technical document to obtain the information of the downloading user, and a leaked person is positioned, so that traceability of the secrete divulger is realized.
