Problems solved by technology

[0002] At present, the anti-counterfeiting methods commonly used in electrical products include physical methods and logical methods. A single physical anti-counterfeiting method is easier to imitate. If the encryption technology is not strong enough for general logical anti-counterfeiting, the effect is not ideal.

Embodiment 1

[0022] In the basic principle diagram of the present invention, the core of the logo-based CPK authentication technology is to closely bind the product logo with the product. The technical solution described in the present invention is shown in the attached drawing, and the electrical products are started to be verified at the production site of the enterprise. Operation of information encryption:

[0023] Step 1. At the production site of the enterprise, first read the ID number of the CPU chip from the communication interface of the CPU chip on the product circuit board and transmit it to the signal reader.

[0024] Step 2, the signal reader converts the ID number of the CPU chip read by the communication interface, and outputs the data converted by the signal reader to the computer.

[0025] Step 3: After the signal reader inputs the converted ID number data into the computer, the CPK program installed in the computer uses the ID number data as an identification to carry ou...

Embodiment 2

[0032] For electrical products without a CPU chip in the circuit, when the chip storing data or programs has an ID number, the ID number can be used as a product identification, complete the product signature and generate a CPK anti-counterfeiting two-dimensional code, and read the ID number The mode is identical with each step of embodiment 1.

[0033]

Embodiment 3

[0035] When there is no chip with an ID number in the circuit of the product, the method of adding a chip with an ID number is adopted. The added chip can only be stored but cannot be rewritten or erased. 2 ROM chip, E 2 The number written in the ROM chip can be used as an ID, and the method of reading the ID number is the same as the steps of Embodiment 1.

[0036]

[0037] Embodiments 1, 2, and 3 can all constitute authenticity, anti-counterfeiting, and traceability systems based on the ID number of the core chip.

Abstract

The invention discloses a CPK authentication false-proof system employing core chip ID number of an electric appliance product as identification. The system is characterized in that the ID number read from a core chip data end is taken as the identification of the product false-proof system, the identification is used for generating a two-dimensional code with a false-proof function, and thus a label which is signed and encrypted through a CPK identification private key is bound with the product; when goods are authenticated, through downloading a disclosed CPK reading program, the encryption information in the label can be read by scanning the two-dimensional code label on the goods, and goods information in the label is read through label verification and decryption by a CPK calculation public key; when a product needing to be counterfeit-proof does not have a readable ID number therein, the product is counterfeit-proof by adding a chip with the ID number; and offline identification authentication of the product can be realized from a recognizer or an intelligent mobile phone, the traceability information of the product can be further known through networking to a service query database, and the service query database can realize general public query and company management query according to query permissions.

Description

technical field [0001] The present invention relates to authenticity, anti-counterfeiting and traceability technology of commodities, in particular to an authenticity, anti-counterfeiting and traceability system constructed with CPK identification authentication technology using the circuit core chip ID number as a binding identifier. Background technique [0002] At present, the anti-counterfeiting methods commonly used in electrical products include physical methods and logical methods. A single physical anti-counterfeiting method is easier to imitate. If the encryption technology is not strong enough for general logical anti-counterfeiting, the effect is not ideal. If the physical anti-counterfeiting method and the logical encryption anti-counterfeiting method are combined, the anti-counterfeiting performance of the product can be greatly improved, especially the CPK combined public key technology with good encryption performance and easy implementation is used as a logic...
