RFID (radio frequency identification devices) data processing method

Abstract

The invention provides an RFID (radio frequency identification devices) data processing method. The method comprises the following steps that an MCU (micro controller unit) is communicated with an access upper computer in order to authenticate user identification, a control chip realizes safe range authentication and data reading and writing and then performs file access control and encryption and decryption after the authentication is finished; the file data of a user is stored in form of cipher text in a flash memory; the safe information is stored in the control chip of a storage system; when the storage system is away from a controlled area, once the storage system enters the reading and writing range of a remote radio frequency reader-writer, the reader-writer writes scope exceeding warning sign remotely to a label chip; when the system is connected with the access upper computer next time, the warning sign in the RFID label chip is detected firstly, the control chip is informed to perform reliable key deletion when the warning sign is existent in the label chip. By utilizing the RFID processing, the authorization use, encrypted storage and reliable deletion of the storage system are guaranteed, so the safe use area of the storage system can be controlled strictly, and the information leakage risk is reduced.

Description

technical field [0001] The invention relates to radio frequency identification, in particular to an RFID data processing method. Background technique [0002] In recent years, storage systems such as U disks and flash disks have been widely used in enterprise organizations as a flexible and fast storage medium. If insiders take out the storage system containing these sensitive information and use it externally, there is a risk of inadvertent disclosure of sensitive information. At present, in the technical solution for the storage system, encrypted storage and user authentication are mainly used to ensure that the information in the system is not stolen by illegal users, but it does not restrict legitimate users from using the device. In some solutions for restricting the use environment of equipment, the access of equipment to the host computer is restricted by installing corresponding software modules or hardware modules in the host computer, but such solutions are not ea...

AI Technical Summary

Problems solved by technology

At present, in the technical solution for the storage system, encrypted storage and user authentication are mainly used to ensure that the information in the system is not stolen by illegal users, but there is no restriction on the use of equipment by legitimate users

In some solutions for restricting the use environment of equipment, the access of equipment to the host computer is restricted by installing corresponding software modules or hardware modules in the host computer, but such solutions are not easy to monitor the use of equipment

[0003] Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed
