Abstract

The invention discloses a data right confirmation method and system based on a block chain technology. The method comprises the following steps: initializing and verifying a digital certificate; generating a user DID and a data DID and uploading the user DID and the data DID; calculating a hash value of the data to be subjected to right confirmation and signing to obtain the hash value and a signature; applying an authoritative timestamp according to the hash value of the to-be-confirmed data; generating a data certificate of the to-be-confirmed data according to the uplink user DID, the data DID, the timestamp, the hash value and the signature, verifying the data certificate, calculating the hash value of the data certificate, and signing the hash value of the data certificate to obtain a signature certificate; and uploading the verified data voucher and signature voucher to obtain right confirmation record uplink hash and returning the right confirmation record uplink hash to the client. According to the invention, the decentralized digital identity DID is adopted, and the data right confirmation information of the to-be-confirmed right data is stored in the block chain in the form of the verifiable certificate, so that the right confirmation function of the to-be-confirmed right data is realized, and the characteristics of verifiability, traceability, tamper resistance and the like of the data right confirmation information are ensured.

Description

technical field [0001] The present application relates to the field of blockchain technology, and in particular, to a method and system for data right confirmation based on blockchain technology. Background technique [0002] Today, data has become a national basic strategic resource, and data is more and more like a commodity, which can be used to buy, sell, transfer and use. However, with the improvement of cloud computing and data-related processing technologies, some problems have also been exposed. The biggest problem currently facing is that "you have seen it, copied it, and owned it". For example, when a piece of data is published on the Internet, others can also reprint and copy it, so that it circulates repeatedly on the Internet, and it is impossible to find out who is the first The second time I wrote this data, there was a problem of unclear ownership. It can be seen that the ownership of the data is very important. [0003] For data to become a digital asset, t...
