s1, the anti-counterfeiting numerical control platform distributes and generates version identification information, user identification information and anti-counterfeiting code values corresponding to commodity information.
The anti-counterfeiting numerical control platform is a preset computer server; the digital tag includes, but is not limited to, an RFID tag and/or an NFC tag, and the card number of the digital tag refers to a card number of the digital tag cured at the time of shipment, i.e., an ID (unique identification information) corresponding to each tag; the digital label read-write equipment comprises, but is not limited to, an NFC read-write card device, and is used for writing anti-counterfeiting traceability information into the digital label or reading the anti-counterfeiting traceability information from the digital label; identification information associated with the digital tag read-write device includes, but is not limited to, a version number of the device, etc.; the user information comprises the name of the client, manufacturer identification and the like; writing the anti-counterfeiting code value, the version and the user identification information into the digital label so as to facilitate commodity tracing; the anti-counterfeiting code value corresponds to commodity information, is used for anti-counterfeiting verification, and is used for enabling commodity information to be in a comprehensive condition, such as cigarettes, wine and the like; the commodity information, the anti-counterfeiting code value and the verification information form an association relation, so that the tracing is convenient.
Specifically, the anti-counterfeiting numerical control platform generates information according to a predefined naming rule or a random algorithm.
S2, after the digital label reading and writing equipment reads the card number of the digital label, hash encryption is carried out on the card number, the identification information, the user information and the anti-counterfeiting code value together, and a verification hash value is generated.
In production, the digital label read-write equipment reads the card number of the digital label first and then carries out encryption processing. Specifically, the hash encryption algorithm is not limited herein, and the verification hash value obtained through hash encryption is related to the card number of the digital label, the identification information associated with the digital label read-write equipment, the user information and the anti-counterfeiting code value, so that the cracking difficulty is increased.

the primary verification module is used for performing primary format verification on the anti-counterfeiting code value and the rolling code, and if verification is successful, the card number, the anti-counterfeiting code value, the rolling code and the verification hash value of the read digital label are sent to the anti-counterfeiting numerical control platform for re-verification;
the tracing verification module is used for searching user information corresponding to the batch of code values and identification information associated with the digital label read-write equipment in the anti-counterfeiting numerical control platform by the anti-counterfeiting code values, and determining the source of the digital label if the user information and the identification information are searched; if not, the source of the digital label cannot be determined;
the tamper-proof verification module is used for performing tamper-proof verification on the digital tag card number, the anti-counterfeiting code value, the rolling code, the version and the user identification information, and performing secondary verification on the digital tag card number, the anti-counterfeiting code value, the rolling code, the version and the user identification information together, and if verification is successful, performing secondary verification on the digital tag card number, the rolling code, the version and the user identification information and the verification hash value in the preset private block chain;
the first updating digital label module is used for sending a verification success signal to the digital label verification equipment together with the version and the user identification information if the secondary verification is successful;
the second updating digital label module is used for the digital label checking equipment to generate a new rolling code according to the current card writing time so as to generate a new checking hash value, and the rolling code and the checking hash value are written into the digital label specific encryption block;
and the synchronization module is used for transmitting the new rolling code to the anti-counterfeiting numerical control platform, generating a new verification hash value by adopting the same encryption method as the digital label verification equipment, and packaging the new verification hash value into operation information to be issued on the preset blockchain.
10. A blockchain-based digital label anti-counterfeiting tracing system, configured to perform the blockchain-based digital label anti-counterfeiting tracing method according to any one of claims 1 to 8, and comprising: the anti-counterfeiting digital control system comprises an anti-counterfeiting digital control platform, digital label reading and writing equipment, a digital label, a preset block chain and digital label checking equipment; the digital tag comprises an RFID tag and/or an NFC tag, and the digital tag reading and writing equipment and the digital tag checking equipment comprise NFC card reading and writing devices; the anti-counterfeiting numerical control platform is computer server equipment.
