Abstract

The invention discloses a block chain integrity verification method based on an EPC global network, relates to the technical field of EPC global networks, and the method comprises the following steps:each data owner uploads ProductInfo information and VerifyInfo information owned by the data owner to an EPCDS, and uploads RegistInfo of the data owner to a block chain; the EPCDS acquires uploadeddata to establish an index for a user to inquire, and returns verification information VO to the user while returning an inquiry result; and the user initiates a query to the EPCDS to obtain a query result and corresponding verification information VO. According to the invention, the product information is stored in the blockchain platform to provide verification of the query result for the user;and meanwhile, a batch number field is newly added to the product information to index the data, so that the storage overhead is reduced while the data uploading efficiency is improved, and the security privacy problem caused by unreliability of the EPCDS is solved, thereby ensuring that the product information queried by the user from the EPCDS is correct and complete.

Description

technical field [0001] The present invention relates to the technical field of EPC global network, in particular, to a blockchain integrity verification method based on EPC global network. Background technique [0002] EPC global network (EPCglobal Network) is a dedicated information network that collects, stores and shares product information through a series of international standards based on the Internet of Things and Internet technologies. EPCDS (EPC DiscoveryService) is the search engine of EPC's global network and the central module for its global product information sharing. In the EPC global network, enterprises publish product information by registering the product information index in EPCDS, and users query the required product information through EPCDS. [0003] The correctness of the EPCDS query results includes the following meanings: (1) The EPCDS query results are true, and they all come from enterprises in the supply chain. (2) The EPCDS query result is co...
