Description

Technical Field

[0001] The present application relates to the field of radio frequency identification technology, and more specifically, to a radio frequency identification method and system. Background Art

[0002] Radio frequency identification technology is a contactless automatic identification technology. Each electronic tag has a unique identification information. The radio frequency reader reads the identification information of the electronic tag through radio frequency. Since the electronic tag is read through radio frequency, it has many advantages such as being able to work in harsh environments, fast reading speed, a large number of tags that can be read at one time, and a long reading distance. Therefore, radio frequency identification technology is widely used in logistics, transportation and access control management.

[0003] The data security issue of radio frequency identification technology is also a compelling topic, and even a key point affecting the future of commercial applications. Since the reading of electronic tag data is triggered by the radio frequency emitted by the radio frequency reader, that is, as long as the malicious radio frequency reader transmits at the same frequency, the electronic tag will respond, allowing the malicious radio frequency reader to read the data in the electronic tag, thereby counterfeiting the electronic tag. Criminals can use these counterfeit electronic tags to illegally infiltrate and commit illegal activities, resulting in unpredictable consequences. Summary of the Invention

[0004] To solve the above problems and technical defects, the present application adopts the following technical solution, a radio frequency identification method, comprising the following steps:

[0005] A random number generator is built into the electronic tag to generate a random number identifier, which is combined with the hardware identifier and timestamp to produce a tag identifier.

[0006] The RF reader outputs a radio frequency signal to the electronic tag, and the electronic tag reads the radio frequency signal in response. The RF reader reads the tag information and tag identifier in the electronic tag, verifies the tag identifier, and determines whether the electronic tag is a normal electronic tag based on the verification result. If so, the electronic tag is allowed to pass identification.

[0007] Preferably, an encoder is installed in the electronic tag, and the radio frequency reader will output a verification test signal before outputting the radio frequency signal. The encoder authenticates the radio frequency reader based on the verification test signal. Only after the authentication is passed will the radio frequency signal be output. If the authentication fails, the encoder encodes the radio frequency signal and outputs an error radio frequency signal.

[0008] Preferably, the random number generator is a TRNG true random number generator, which adopts a dynamic frequency authentication protocol and updates the random number identifier every preset time period based on a time slot allocation algorithm.

[0009] Furthermore, the radio frequency signal output by the radio frequency reader includes a randomly selected time period range, the time period range is within the interval between the current time and the operating time of the electronic tag, and the time length of the time period range matches the preset time period of the random number generator;

[0010] The tag identifier replied by the electronic tag includes the most recently generated tag identifier and the tag identifier corresponding to the time period range.

[0011] Furthermore, the radio frequency reader verifies the tag identifier including:

[0012] Use the preset root certificate combined with the timestamp to verify the random number identifier generated by the random number generator;

[0013] Verify the hardware identification in conjunction with the cached hardware encoding list;

[0014] If one of the verifications fails, the electronic tag is judged to be an abnormal electronic tag and the electronic tag identification fails.

[0015] Furthermore, a wireless communication module is installed in the radio frequency reader. When the radio frequency reader determines that the target electronic tag is an abnormal electronic tag, it will record and mark the target electronic tag. At every preset period, the radio frequency reader establishes a communication connection with the service terminal through the wireless communication module and uploads the recorded and marked target electronic tag data. The service terminal then sends it to other radio frequency readers. The radio frequency reader does not allow the recorded and marked electronic tags to be recognized.

[0016] A radio frequency identification system, comprising:

[0017] Electronic tags, used to store identification information;

[0018] Radio frequency reader, used to output radio frequency signals and read identification information stored in electronic tags;

[0019] The random number generation module is installed in the electronic tag and is used to generate a random number identifier, which is combined with the hardware identifier and the timestamp to produce a tag identifier;

[0020] The identification verification module is installed in the radio frequency reader and is used to determine whether the electronic tag is a normal electronic tag based on the verification result of the tag identifier and whether to allow the electronic tag to be identified.

[0021] Preferably, a signal encryption module is further included. Both the electronic tag and the radio frequency reader are equipped with the signal encryption module for encrypting and decrypting the radio frequency signal output by the radio frequency reader and the identification information and tag identifier returned by the electronic tag.

[0022] An electronic device includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, the content of the wireless radio frequency identification recognition method as described above is implemented.

[0023] A computer-readable storage medium stores a computer program thereon, wherein the computer program, when executed by a processor, implements the content of the above-mentioned radio frequency identification method.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] This application generates a random number identifier through a random number generator, combines it with the hardware identifier and timestamp to produce a tag identifier, verifies the tag identifier, and determines whether the electronic tag is a normal electronic tag based on the verification result. If so, the electronic tag is allowed to be identified, thereby preventing malicious radio frequency readers from reading the data in the electronic tag and preventing counterfeit electronic tags from being read and identified by radio frequency readers, thereby improving the accuracy of radio frequency identification.
