Abstract

The invention relates to the technical field of commodity traceability, in particular to a commodity traceability block chain system and a secret key storage and retrieval method. The system comprisesan enterprise party unit, a supervisor party unit, a producer sub-workshop unit, a supervisor sub-workshop unit and a plurality of sub-workshop employee units, a supervision department is added intothe system, whole-process information supervision of the whole production process of commodities is achieved, so that the issued information has higher authority, and the appearance of counterfeit andinferior products in the market is effectively eradicated. According to the secret key storage and retrieval method, the watermark adopts a frequency domain blind watermark adding method, so that thehiding property and the attack resistance of the watermark are stronger; besides, the digital watermarking mode is adopted, and extraction of the secret key information is not influenced by distortion conditions related to image gray level and the like, so that the secret key storage and retrieval method combines the image threshold secret segmentation technology with the digital watermarking technology, and the secret key storage is safer and more reliable in extraction.

Description

technical field [0001] The invention relates to the technical field of commodity traceability, in particular to a commodity traceability blockchain system and a method for storing and retrieving secret keys. Background technique [0002] As people's requirements for product quality increase, more and more enterprises and investment institutions have entered the field of product traceability, and blockchain technology has also been applied in this field. However, due to the anonymity of blockchain technology, there are some problems in practical applications, such as the supervision of information in blockchain and the inability to retrieve private keys after loss. These problems seriously restrict the practical application of blockchain technology. Applications. In addition, in terms of commodity anti-counterfeiting identification, although there are many solutions, it still cannot completely eliminate the appearance of fake and inferior products in the market. Therefore, ...
