Abstract

The invention discloses a supply chain transaction privacy protection system based on a block chain, and the system comprises: core enterprise node equipment which is used for encrypting payable committed by a core enterprise to a first-level supplier to obtain a confidential transaction, carrying out the signature of the confidential transaction, and uploading the signed transaction data to a supply chain platform based on the block chain; a first-level supplier node equipment which is used for receiving the confidential transaction, decrypting the confidential transaction, outputting the decrypted confidential transaction to a first-level supplier, and sending an obfuscation request for a split transaction in the confidential transaction to the obfuscation service provider node equipment; an obfuscation service provider node device which is used for obfuscating the split transaction into other transactions equivalent to the split transaction; and a supply chain platform based on theblock chain which is used for storing the received transaction data. The invention further provides a supply chain transaction privacy protection method based on the block chain and related equipment.According to the invention, transaction privacy can be protected from being leaked, and anonymity of the transaction is realized, so that anyone cannot track a receiver of the transaction.

Description

Technical field [0001] The present invention relates to the field of blockchain technology, and in particular to a blockchain-based supply chain transaction privacy protection system, method and related equipment. Background technique [0002] The existing blockchain-based supply chain system connects core enterprise node equipment, supplier node equipment, factor node equipment, and bank node equipment through the blockchain. When core enterprise node equipment, supplier node equipment, factorer node equipment, and bank node equipment are used as blockchain nodes to join the blockchain-based supply chain system, they need to be authorized to join, and there is a certain amount between blockchain nodes. Based on the trust basis, the credibility of the data is enhanced by the way of transaction data such as accounts receivable, bill vouchers, and mortgage goods vouchers. [0003] However, these transaction data often contain commercial secrets, and the transaction data is written o...
