Problems solved by technology

However, while the radio frequency card is convenient to read, it also reduces the security of its own information.
For example, some criminals obtain some private radio frequency card information without the permission of others, and then copy the obtained private radio frequency card information, steal property by copying ID card, bank card and other information, or use loopholes to store data on the card. Data destruction, causing huge economic losses to users

Abstract

Embodiments of the invention provide a data protection method and apparatus. The method comprises the steps of obtaining a radio-frequency signal; determining attribute information of the radio-frequency signal; for the attribute information, judging whether a response signal of making a response to the radio-frequency signal is generated or not in a preset distance range; and if yes, for the radio-frequency signal and / or the response signal, generating an interference signal with the same attribute information as the radio-frequency signal and / or the response signal, thereby disturbing communication between a reader and a radio-frequency card. Therefore, the problem that data in the radio-frequency card is easily copied at present is solved, the security of the data in the radio-frequency card is protected, and the possibility of data stealing is avoided.

Description

technical field [0001] The present application relates to the technical field of Internet information security, in particular to a data protection method and a data protection device. Background technique [0002] Radio Frequency Identification (RFID) is a wireless communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. [0003] The advantage of radio frequency identification technology is that users can easily read the relevant information of some radio frequency cards through the reader in a non-contact manner. It is easy to operate, simple and practical, and can work freely in various harsh environments. Passports, payment cards (credit cards, bank cards, etc.), libraries, access control systems, food safety traceability and other fields have begun to widely use radio frequency identification technology. Howe...
