Security label, security method and security system based on dynamic ciphers

Abstract

The invention provides a security label, a security method and a security system based on dynamic ciphers. The security label comprises a dynamic cipher generation unit, a near field communication unit and a power supply unit, wherein the dynamic cipher generation unit is used for generating dynamic ciphers, the near field communication unit is used for sending the dynamic ciphers and an identification code of a product corresponding to the security label to a mobile terminal through the near field communication technology to carry out security authentication for the product, and the power supply unit is used for supplying power for the dynamic cipher generation unit and the near field communication unit. According to the security label, the dynamic ciphers are for security authentication, the multiple dynamic ciphers can be generated for one same product so that information disclosure of the dynamic ciphers and forgery can be avoided, so one same product can be authenticated for multiple times, a problem of single authentication caused by authentication failure after one time authentication because of information disclosure of a fixed authentication cipher in the prior art can be solved.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting authentication of electronic labels, and in particular relates to an anti-counterfeiting label, an anti-counterfeiting method and an anti-counterfeiting system based on dynamic password and near-field communication technology. Background technique [0002] The anti-counterfeit labels in the prior art are usually authenticated through the product ID (Identity) set in the label, but the ID code of the product is usually set in the label during the production process of the product. In order to avoid subsequent counterfeiting, these ID codes are usually invalid after being authenticated once. Moreover, during authentication, the user is usually required to manually input the ID code for verification, which is laborious to operate, and the ID code is usually long, which may require multiple input and careful inspection, which is time-consuming and laborious, and the accuracy rate is low.
