Information processing method based on radio frequency identification

The invention provides an information processing method based on radio frequency identification. The method includes the steps: encrypting and storing all files in a system, and encrypting and decrypting the files apparent to a user performing reading and writing operations; uniformly setting a user name and passwords when initializing each storage system, and authenticating a user's identity in the access process; encrypting the files by a file private key, only presenting the file of the user and performing access control after identity authentication; authenticating the access level of an upper computer according to level signals of a detection pin on a USB (universal serial bus) socket when the storage systems access the upper computer; deploying an RFID (radio frequency identification) reader-writer at an exit of a controlled area when the upper computer is legally accessed, ensuring that the system can only perform normal reading and writing when accessing the legal upper computer in the controlled area, and deleting the stored private key if the system is taken out of the controlled area. By RFID processing, authorized use, encrypted storage and reliable deletion of the storage systems are ensured, so that safety use areas of the storage systems can be strictly controlled, and the risk of information leakage is reduced.
