[0002] When a user needs to query some data, it is generally necessary to verify whether the user has the corresponding authority. At this time, the user is required to provide the corresponding user information. Since the user information cannot be guaranteed after the user provides the user information, the user can be obtained The information party may disclose or illegally use the user information
Therefore, in the prior art, when a user needs to query certain data, the security of the user information provided by the user is relatively low

The present invention provides a data processing system and method based on secure multi-party computing. The system includes: multiple nodes and user terminals; each node is provided with a distributed ledger; When processing data, the whole process data is saved in the distributed ledger of the node, and the distributed ledger of the node is synchronized with the distributed ledger of other nodes; the user terminal is used to receive the user information sent by the requesting user, and send the user information to the user. Transcode the information, generate ciphertext, and send the ciphertext to each node; when the node receives the ciphertext sent by the user terminal, it is used to judge whether the requesting user has the full information in the distributed ledger according to the ciphertext. The authority of the process data, and publish the corresponding authority result of the requesting user; the node is used as a consensus node to determine whether to allow the requesting user to query the whole process data according to the authority result of each node. The invention can improve the security of user information.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a data processing system and method based on secure multi-party computing. Background technique [0002] When a user needs to query some data, it is generally necessary to verify whether the user has the corresponding authority. At this time, the user is required to provide the corresponding user information. Since the user information cannot be guaranteed after the user provides the user information, the user can be obtained The information party may disclose or illegally use the user information. Therefore, in the prior art, when a user needs to query certain data, the security of the user information provided by the user is relatively low. Contents of the invention [0003] Embodiments of the present invention provide a data processing system and method based on secure multi-party computing, which can improve the security of user information. [0004] In the first aspect...
