Abstract

The invention discloses a data privacy protection method in supply chain finance based on a block chain technology, and the method comprises the steps of firstly building a Hyperledger permission chain network environment, and then deploying corresponding multiple channels according to a multi-business process existing in an actual scene of supply chain finance; adding corresponding Organizations into each channel to represent core enterprises, small and medium-sized enterprises applying for financing and financial institutions; then designing a prepayment financing model, and deploying a chain code for applying for the prepayment financing model by small and medium-sized enterprises and an attribute-based access control chain code in each channel; finally, adding a private database into each channel, so that only authorized organizations can see private data values, and unauthorized organizations can only see corresponding Hash. The method solves the problems that in the prior art, data cannot be isolated, sensitive data in an enterprise is easy to leak, and information access permissions of different departments in the enterprise cannot be subdivided.
