Based On The Data Encryption And Information Management System Design And Implementation

As the information network in China’s rapid development of network-based Library and Information Management System in China’s colleges and universities be popular. With the computer library management and information retrieval has a very bright future. But along with automation of library and information from the data security issues. Using computer management, traditional libraries and information processing various types of directories business cards, all kinds of books, registration records will be used on magnetic storage media data files instead. This network of Library and Information Management event security issues, entirely possible in a few seconds so that stored in a computer in the hundreds of thousands of copies, information on millions of books has become without a trace. Therefore, the library and information management systems in the data security problem has become an imminent and urgent need to solve the big problem.This thesis focuses on library and information management system, the security user interface design and database security design two aspects to consider how to prevent the destruction of data and information systems to prevent illegal tampering and theft, as well as data destroyed to return to the correct state means. In the whole life cycle of data to maintain its integrity, accuracy and confidentiality. In this thesis, specifically from the authentication, permissions, settings and user account management, the role of agents, security audit, sensitive areas such as data encryption, data security on the network design.
