Abstract

The invention discloses a private data processing method, device and equipment of a block chain and a storage medium, relates to the technical field of block chains, and can be used for cloud computing and cloud service. According to the specific implementation scheme, acquiring a data authorization request sent by a data owner, wherein the data authorization request comprises to-be-authorized data and a block chain account address of a data user, and the to-be-authorized data at least comprises encrypted data; in the trusted computing environment, according to the block chain account addressof the data user, performing authorization processing on the encrypted data in the to-be-authorized data to obtain authorized data or a data use certificate of the to-be-authorized data; and sending an uplink transaction request comprising a data use certificate of the authorized data or the to-be-authorized data to a block chain network for uplink storage. Therefore, the complexity of privacy data authority management is reduced.

Description

technical field [0001] This application relates to the field of computer technology, in particular to blockchain technology, and in particular to a method, device, device, and storage medium for private data processing of blockchain. Background technique [0002] With the development of blockchain technology, it has been gradually implemented in many application scenarios. In practical applications, privacy protection is required for data involving key business scenarios to ensure the interests of users; at the same time, in some business scenarios, users’ private data needs to be used for calculation, and regulators also need to check the specific data content Wait. Therefore, it is necessary to manage the access rights of users' private data. [0003] However, at present, data access rights are mainly managed by maintaining access control lists, or encryption based on user attributes, and the management complexity is high. SUMMARY OF THE INVENTION [0004] The present...
