[0002] With the rapid development of information technology, traditional paper - based archive management methods have gradually revealed problems such as low efficiency, insufficient security, and inconvenient management. Paper archives not only occupy a large amount of physical space but are also prone to damage or loss during the processes of searching, copying, and transmission. At the same time, they are not convenient for remote access and sharing. Therefore, enterprises urgently need to introduce new technical means to improve the efficiency, security, and convenience of archive management.

[0003] Digital archive management methods have emerged as the times require. By converting paper archives into digital forms, they have realized the electronic storage, retrieval, and management of archives. Digital archive management methods not only save physical space but also improve the speed and accuracy of archive retrieval, while enhancing the security and confidentiality of archives. However, despite the many advantages of digital archive management methods, they still face some challenges in practical applications. Traditional digital management methods lack flexibility and intelligence, resulting in cumbersome archive management processes and difficulty in adapting to the changing needs of enterprises. In addition, there is a lack of a unified evaluation standard to determine the preservation duration and value of digital archives, especially how to achieve efficient, secure, and convenient management of the full life cycle of digital archives.
