Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, it is a flow chart of the anti-counterfeiting tracing method of the present invention.
The anti-counterfeiting tracing method comprises the following steps:
s1, the brand business server and the point-of-sale terminal server encrypt the original product serial number of the RFID label twice to obtain an encrypted product serial number, and the encrypted product serial number is written into the RFID label;
s2, the point-of-sale terminal and the RFID label carry out mutual authentication based on the own stored private key and the public key of the other party, and the point-of-sale terminal acquires the encrypted product serial number from the RFID label after the point-of-sale terminal passes the authentication;
s3, the point-of-sale terminal sends the encrypted product serial number to a point-of-sale terminal server and a brand server for decryption to obtain the original product serial number, and the brand server returns the record of the original product serial number to the point-of-sale terminal.
Because the record of the original product serial number only exists in the brand provider server, the point-of-sale terminal must pass the mutual authentication of the step S2 and the RFID label, the obtained encrypted product serial number can be obtained after the authentication is qualified, and then the record of the original product serial number can be obtained from the brand provider server by means of the encrypted product serial number, no response can be made to the point-of-sale terminal with unqualified authentication, the authentication process is carried out based on the private key of the point-of-sale terminal and the public key of the opposite side, and the encrypted product serial number is obtained by twice encryption of different servers, the communication confidentiality is enhanced, the real product serial number and other product information can not be obtained by intercepting a communication packet, the RFID label can not be copied or cracked, and because the secret key is distributed and authorized, all information can be obtained only by obtaining all secret keys, the source and the authenticity of goods can be, the data security management in the anti-counterfeiting traceability system is enhanced, and the information can be prevented from being cracked, stolen and tampered by unauthorized personnel of goods manufacturers, sales channels and actual operators of terminal manufacturers
The individual steps are described in detail below.
Regarding step S1:
step S1 is primarily for generating an encrypted product serial number. The original product serial number may preferably be 1024 bits, which satisfies both reliability and economy. Step S1 specifically includes:
s11, uploading the original product serial number of the RFID label to a brand server, and encrypting the original product serial number by the brand server based on a built-in first key by adopting a digital signature algorithm of an asymmetric password to obtain an intermediate product serial number;
s12, the brand provider server uploads the intermediate product serial number to a point-of-sale terminal server, and the point-of-sale terminal server encrypts the intermediate product serial number by adopting a digital signature algorithm of an asymmetric password based on a built-in second key to obtain the encrypted product serial number;
and S13, writing the encrypted product serial number into the RFID label.
It can be seen that the keys involved in the encryption of the original product serial number are dispersed in two servers, and when the label records are read at the later stage, decryption of the two servers must be performed again, so that the key dispersion authorization is realized, all information can be obtained only by obtaining all keys, the source and authenticity of goods can be accurately identified, the data security management in the anti-counterfeiting traceability system is enhanced, and cracking, stealing and tampering of the information by non-authorized personnel of goods manufacturers, sales channels and actual operators of terminal manufacturers can be prevented; further, the RFID label also has the characteristic of removal prevention.
Regarding step S2:
step S2 is mainly a reading process of the RFID tag by the point-of-sale terminal, where the reading process involves a private key of the point-of-sale terminal and a public key of the other party. After being written, the key in the RFID tag can only participate in operation and cannot be read, so that the tag cannot be copied or cracked.
And the point-of-sale terminal encrypts the data communicated between the RFID tags by using a private key of the point-of-sale terminal, and then uses a public key of the other party to solve corresponding information. An unauthorized point-of-sale terminal cannot have a built-in private key, and when the unauthorized point-of-sale terminal communicates with the RFID, the private key cannot be used for encryption, so that the RFID tag cannot be decrypted by using a public key to obtain a corresponding instruction, and the RFID tag only responds to the point-of-sale terminal which can pass signature verification.
Therefore, data such as the encrypted product serial number in the tag is stored in a secure area, a public key of the other party is needed to unlock the tag, and the data can only be read by an authorized point-of-sale terminal.
Specifically, step S2 includes:
s21, the point-of-sale terminal encrypts the instruction based on a built-in private key of the point-of-sale terminal and sends the instruction to the RFID label;
s22, the RFID label decrypts the received instruction based on the built-in public key of the opposite side, encrypts the stored encrypted product serial number based on the built-in private key of the RFID label and sends the encrypted product serial number to the point-of-sale terminal;
and S23, the point-of-sale terminal decrypts the received encrypted product serial number based on the built-in public key of the other party.
Step S2 realizes mutual authentication of the point-of-sale terminal and the RFID label, the RFID label only responds to the point-of-sale terminal qualified in authentication, and the communication data between the RFID label and the point-of-sale terminal are encrypted, so that the communication confidentiality is enhanced, other people cannot obtain the real product serial number and other product information by intercepting the communication packet, and the RFID label cannot be copied or cracked.
Regarding step S3:
step S3 is a process in which the point-of-sale terminal obtains a record of the product. Since step S1 is subjected to two-pass encryption, step S3 correspondingly requires two-pass decryption to obtain the record corresponding to the original product serial number. Specifically, step S3 includes:
s31, the point-of-sale terminal sends the encrypted product serial number to a point-of-sale terminal server, and the point-of-sale terminal server decrypts the encrypted product serial number based on a built-in second secret key to obtain an intermediate product serial number;
s32, the point-of-sale terminal server uploads the intermediate product serial number to a brand server, and the brand server decrypts the intermediate product serial number based on a built-in first secret key to obtain an original product serial number of the RFID label;
and S33, the brand provider server returns the record corresponding to the original product serial number to the point-of-sale terminal through the point-of-sale terminal server.
Preferably, in order to prevent the RFID tag from being removed, the body of the RFID tag is made of a fragile material and is adhered to a product through a strong back adhesive.
