Abstract

The invention provides a block chain-based private data mapping method, which is applied to a private data mapping publisher, and comprises the following steps: generating published data corresponding to private data based on the held private data, and publishing the published data to a block chain for evidence storage; acquiring application data which is stored in a block chain and issued to the block chain by the applicant; and in response to the obtained application data, performing zero-knowledge verification on the zero-knowledge proof, and when the verification is passed, issuing indication information for indicating that the verification of the zero-knowledge proof is passed to the block chain for evidence storage. According to the technical scheme, on one hand, the privacy data held by the two mapping parties can be effectively protected, and the data security of the two mapping parties during mapping is improved; and on the other hand, a mapping relationship can be more conveniently established among a plurality of service providers with the same privacy data, and multi-party cooperation is realized.

Description

technical field [0001] One or more embodiments of the present application relate to the field of blockchain technology, and in particular to a blockchain-based private data mapping method, device, medium, and electronic equipment. Background technique [0002] Usually, when a user uses a service provided by a certain service provider, he can introduce other service providers so that multiple service providers can serve the same user. For example, when a user uses a certain taxi-hailing software, he can use the taxi-hailing software to travel and use the payment software to complete the payment by binding the user's account in a certain payment software, so that there is no need to bind a bank card to the taxi-hailing software. It can be seen that through multi-party cooperation of multiple service providers, user experience can be improved and more convenience can be brought to users. [0003] In order to realize the above-mentioned multi-party collaboration, it is necessar...
