Abstract

This paper focuses on developing a modern architecture for electronic libraries that effectively combines artificial intelligence tools and a high level of information security. A digital repository system is proposed where smart algorithms autonomously analyze uploaded PDF documents and generate metadata (summaries, keywords, authors) for them. This eliminates the routine work of administrators. Furthermore, to address the issue of copyright protection, the system implements Role-Based Access Control (RBAC) based on JWT tokens. It automatically determines whether a user can download a book, considering its license type and the client's current IP address. The implementation of vector search through the PostgreSQL database significantly improves literature retrieval based on its content.
