Abstract

The invention provides a blockchain-based trusted data calculation method. The method includes the following steps: electronic evidence issuance, electronic evidence storage, and authorized use of electronic evidences. According to the blockchain-based trusted data calculation method proposed by the invention, the secure storage and effective use of the electronic evidences of users can be effectively realized.

Description

technical field [0001] The present invention relates to block chain technology, in particular to a trusted data calculation method based on block chain. Background technique [0002] Electronic evidence involves privacy and security issues, and only authorized users can access relevant electronic evidence. Data anonymity can be used to protect the security of personal electronic evidence data. In terms of data privacy protection, there are already a variety of technologies for privacy protection of personal data. Including making each private information indistinguishable from other records by constructing an anonymous data set, or realizing privacy protection by redistributing private information, or encrypting private data and allowing any calculation to run on the ciphertext. The traditional electronic evidence storage mode adopts a centralized mode, and the data security model relies on the establishment of multi-factor authentication access control. However, this als...
