Sharing Confidential Documents Management System for Multiuser

In an enterprise environment, various types of information are distributed. Information to be distributed can be distributed in text, audio, or video types, but the most basic distribution unit is a document file. Some organizations may distribute confidential information by storing it in a file. Only limited users can access these files, and unauthorized access should be blocked. In this study, we propose a confidential document file sharing technique that allows only limited users to access and check the contents. The proposed technique uses encryption technology and uses a key management system. Due to these characteristics, only pre-defined users can access. As a result of verifying the function to confirm the effectiveness of the targeted confidential document technique, it was confirmed that all the targeted functions were provided. Because this study uses encryption technology, the performance is slower than the legacy method. Additional research is needed to improve this.
