Problems solved by technology
[0003] At present, the data traceability system applied to industrial data exchange is just that the data sender uploads the exchange file to the blockchain, and the data receiver obtains the exchange file uploaded by the data sender from the blockchain. During the entire exchange process The information of the data sender or data receiver is not recorded. Therefore, if the data in the file is leaked, it is impossible to determine from which link the data in the exchange file is leaked.

The invention provides a traceability system and traceability method based on blockchain data exchange. The traceability system comprises: a data sending device used for determining a digital watermark corresponding to a data sender, storing a to-be-sent file uploaded by the data sender superposed with the digital watermark in a block chain as a target sending file, and sending a data sending notification to a data receiver; a data receiving device which is used for obtaining a target sending file stored by the data sending device from the blockchain according to the received data sending notification sent by the data sending device; a data tracing device which is used for uploading a to-be-traced file with data leakage and determining the leakage information of the to-be-traced file according to the digital watermark in the to-be-traced file. The leakage information and existing problems can be estimated more quickly and accurately according to the digital watermark in the file when the data in the file is leaked based on a block chain technology, and the loss caused by file leakage is reduced to the greatest extent.
Description
technical field [0001] This application relates to the field of Internet technology, in particular to a traceability system and traceability method based on blockchain data exchange. Background technique [0002] Blockchain technology is a decentralized trust mechanism reconstructed through distributed technology and consensus algorithm, which realizes information sharing among all participants. Based on the characteristics and advantages of decentralization, transparency, fairness and openness of blockchain technology, the combination of blockchain technology and manufacturing management will promote safe collaboration and sharing among manufacturing enterprises and improve production efficiency , to achieve transaction diversification and low cost. [0003] At present, the data traceability system applied to industrial data exchange is just that the data sender uploads the exchange file to the blockchain, and the data receiver obtains the exchange file uploaded by the dat...
