With the development of information technology, distributed storage, as an advanced and efficient data processing technology, plays an important role in information management system. This paper designs a visualization system based on DES algorithm. This system manages and allocates resources to users. First, analyze the requirements from the database, and then classify them into users, administrators and other roles according to the actual situation and establish the corresponding structure to realize the control of role permissions. Finally, through the establishment of the corresponding model, the function of the distributed database system is improved, and the security of the system is tested through the simulation experiment. The experimental results show that the distributed database system based on the improved DES algorithm can read the requested data within 10s, and the success rate of intercepting and decrypting operations is more than 90%. This shows that the algorithm performs well in the security of the protection system.
