With the development of computer network and multimedia information processing technology, archive management has developed to digitalization and networking, so that digital archive materials have the reproducibility and wide dissemination of information, and the problems caused by covering, alteration or forgery, infringement and other problems have also emerged. The use of Yufei digital watermarking technology can effectively protect digital archives and prevent illegal and improper use of digital archives. The system can effectively protect the file data from hacker attacks, prevent the file data from being illegally modified or replaced, verify the validity of the file and improve the audit efficiency by detecting the integrity of the watermark. Basic operation process: In the process of file digitization, the digital watermark is embedded through the anti-counterfeiting traceability system and stored in the database: when the file adjustment application is received, the watermark integrity of the digital file is detected through the system, and if the watermark is detected abnormally, the paper file is retrieved for comparison; If the detection watermark is normal, you can directly print the archive materials, and at the same time embed the printed digital watermark and the "special seal for file copying" on the printout, which plays the role of anti-copying and anti-calculation modification; Submit the paper copy of the file materials to the file transfer applicant to complete the entire file transfer application process.
