The Design And Implementation About Data Security Protection System

This thesis analyses the main technologies of data secure protection. In light of the current trend of data protection, it also discusses the design and realization of data security system.The data security protection system researched in the thesis is developed mainly for resolving the problems of potential leakage of confidential data during the process of storage and accessing. The system can store the confidential data in using high-tensile encrypted algorithm, and can cut off the link of internet automatically while the data is being accessed.The thesis illustrates the methods to realize RSA and AES encryption algorithm technology, USB electronic key technology, virtual disk drive technology, files filtering and hiding technology, automatic network protection technology and so on. Moreover, it realizes the data encryption and solves the problem of encrypted storage of data; realizes the intelligent network protection and prevents the protected files from being stolen; realizes the safe deletion of files and avoids the finding of deleted files; and also realizes the automatic hiding of files and makes sure that the encrypted files will not be found by unauthorized users. Basically, the system technologically eliminates the problems of secret leakage.
