Description

Technical Field

[0001] This invention relates to the field of digital encryption technology for anti-counterfeiting and traceability of goods, and is particularly applicable to the whole-process anti-counterfeiting verification scenario of consumer products with one item, one code and toxicological safety test records. Background Technology

[0002] Existing QR codes for consumer product traceability mostly use ordinary self-adhesive labels, which can be completely transferred and reused after removal. Unscrupulous merchants counterfeit genuine products by recycling old codes and reprinting them. Conventional verification only compares the code number and does not bind the product's physical tamper-proof status, individual product testing records, and encrypted information on the code, creating anti-counterfeiting vulnerabilities. At the same time, traditional encryption schemes only perform single-digit verification and do not achieve linkage verification between physical damage signals and cloud-based detection and credit data, failing to prevent counterfeiting, cross-selling, and tampering from three layers: physical carrier, digital encryption, and security records. Summary of the Invention

[0003] (1) Purpose of the invention Overcoming the shortcomings of existing anti-counterfeiting labels, such as transferability, single encryption verification dimension, and independent detection files and anti-counterfeiting codes, this paper provides an irreversible and destructible tamper-proof intelligent inspection code method with one-item-one-code encryption binding and authenticity verification. This method achieves triple anti-counterfeiting measures: physical opening renders the label invalid, single-item information is encrypted and locked, and detection data is linked for verification. It also prevents the reuse of old codes and the tampering of product security information by batch counterfeiting codes.

[0004] (2) Technical solution A method for one-item-one-code encryption binding and authenticity verification of irreversible damage-resistant tamper-proof smart inspection codes, characterized by including a factory encryption binding step, a tamper damage signal acquisition step, and a cloud-based multi-layer authenticity verification step; 1) Factory encryption binding step: collecting the unique hardware code of each item, the hash value of the consumer product toxicology test report, the production batch, and the manufacturer's filing key, and generating a unique encryption private key for each item through an asymmetric encryption algorithm; writing the encryption private key into the smart inspection code cloud database, and simultaneously generating a publicly available query public key; binding the encryption private key with the smart inspection code physical identifier... 1) Unique binding: Establish a cloud-based evidence index that corresponds one-to-one with the product ID, encryption key, and toxicology security file; 2) Unsealing damage signal collection steps: When a consumer unseales a product, the physical carrier of the smart inspection code is irreversibly damaged; the mobile scanning terminal reads the damage feature code of the code body, packages the damage feature code, scanning device information, and current timestamp, and uploads them to the traceability and credit cloud; 3) Cloud-based multi-layer authenticity verification steps: After receiving the scanned data packet, the cloud performs three-layer parallel verification: First layer verification: compare the plaintext ID of the smart inspection code read by scanning. The first layer of verification checks whether the product ID matches the one registered in the cloud. If they don't match, it's immediately identified as counterfeit. The second layer of verification extracts the damaged feature code from the data packet and compares it with the baseline features of the complete code body pre-stored in the cloud. If the code body is irreversibly damaged, the smart inspection code is marked as a one-time invalidation, and subsequent scans will be directly blocked. The third layer of verification uses the public key to decrypt the encrypted private key stored in the cloud, retrieves the bound consumer product toxicology risk detection credit data, and pushes it to the scanning terminal to display the complete security profile. If all three layers of verification pass, it is determined to be genuine and the product is opened for the first time. If any layer of verification fails, an anti-counterfeiting anomaly warning is output, and the abnormal scanning data is permanently stored in the cloud as evidence. Furthermore, the asymmetric encryption algorithm uses RSA encryption, the hash value of the toxicology detection report is calculated using the SHA256 algorithm, and all encrypted data, damage records, and scanning logs are solidified and stored in the cloud using a consortium blockchain, making them tamper-proof and deletable. Furthermore, when the cloud-based smart code identification exhibits abnormal behavior such as secondary scanning, cross-regional batch scanning, or multiple queries despite the code being undamaged, it automatically pushes alerts to the manufacturer's backend regarding the risks of cross-selling and counterfeiting.

[0005] (3) Beneficial effects 1) Employing a dual binding mechanism of physical irreversible damage and digital encryption, the labels cannot be reused after removal, completely solving the problem of counterfeiting through the recycling and reuse of old codes; 2) Embedding individual product toxicology and safety testing files into an encrypted key system, anti-counterfeiting verification simultaneously retrieves security information, achieving integrated anti-counterfeiting and consumer product safety identification; 3) A three-tiered verification logic ensures that single counterfeit codes, tampered testing data, and transferred labels cannot pass complete verification, resulting in a higher anti-counterfeiting barrier; 4) All scanned, damaged, and encrypted verification data are stored on the cloud blockchain, ensuring data immutability and serving as valid evidence for rights protection and quality inspection verification; The pure algorithmic process and cloud interaction logic do not rely on specific mechanical structures, making it compatible with the universal deployment of various webbing-type and laminated tamper-evident labels.

In the figure: 1 - Factory encryption binding module, 2 - Irreversible smart inspection code, 3 - Mobile scanning terminal, 4 - Traceability credit cloud server, 5 - Manufacturer management backend, 6 - Consortium blockchain evidence storage node; When the product leaves the factory, the factory encryption binding module 1 completes the encryption binding of the single product information and corresponds it to the irreversible smart inspection code 2; The irreversible smart inspection code 2 corresponds to two scanning flows, and the data is uniformly transmitted to the mobile scanning terminal 3; The mobile scanning terminal 3 and the traceability credit cloud server 4 have bidirectional data interaction; The traceability credit cloud server 4 and the consortium blockchain evidence storage node 6 are bidirectionally connected to complete the detection and anti-counterfeiting data solidification and evidence storage; When the traceability credit cloud server 4 identifies abnormal information, it pushes alarm data down to the manufacturer management backend 5. Figure 2 is a flowchart of the three-layer cloud-based authenticity verification process. In the diagram: 1: Scan data packet input module; 2: Single item ID matching and verification module; 3: Code body damage status feature comparison module; 4: Counterfeit warning output port; 5: Smart inspection code permanent invalidation mark port; 6: Genuine product safety inspection report output port; 7: Abnormal log on-chain and manufacturer backend alarm module. Process logic: The scan data packet is input into module 1, simultaneously outputting a counterfeit warning (module 4) or entering module 2; after verification, module 2 outputs an invalidation mark (module 5) or enters module 3; after comparison, module 3 outputs a genuine product report (module 6) or enters module 7 to complete abnormal evidence storage and alarm. Detailed Implementation Example

[0007] In the consumer product manufacturing process, the equipment collects the individual product serial number and the full text of the fabric toxicology and hazardous substance test report. It calculates the report hash value using SHA256 and combines it with the manufacturer's exclusive key to generate a 256-bit encrypted private key for the individual product using the RSA algorithm. The cloud database establishes a one-to-one correspondence between the serial number, hash value, and private key, generates a public key that can be scanned and queried externally, and associates it with the smart inspection code file.

[0008] When goods reach the end consumer, the consumer tears open the product packaging, causing irreversible damage to the smart code carrier; the mobile phone scans the code to identify the damage feature code, and uploads the code, device number, and timestamp to the cloud.

[0009] The cloud sequentially performs ID matching verification, code integrity verification, and private key decryption file verification. If the code is identified as damaged, the cloud permanently marks the smart inspection code as invalid, and scanning the code again will directly prompt that the code has been opened and is invalid. After all three layers of verification pass, the terminal displays the complete toxicological risk classification of the product, the testing agency's registration information, and the circulation traceability record.

[0010] When the system scans the same smart code multiple times in a short period of time, or scans the code on multiple devices in different locations, the cloud automatically generates a risk report and pushes it to the enterprise management backend to combat cross-selling and large-scale counterfeiting.
