Private data analysis method based on block chain and computer readable storage medium

Abstract

The invention provides a privacy data analysis method based on a block chain and a computer readable storage medium. The method comprises the following steps: acquiring privacy data authorized by an account and a data use scene; intelligent contracts corresponding to the data use scenes are called, the intelligent contracts are compiled in advance according to data evaluation models provided by a data utilization party, and each data evaluation model is used for rating one data use scene; decrypting the privacy data by a preset parser, and transmitting the decrypted privacy data into the called smart contract; and the operation process of the smart contract is encrypted and then stored on the block chain, and the operation result of the smart contract is fed back to the data utilization party. According to the scheme, under the condition that privacy data is not exposed, it is guaranteed that the data is real and not tampered, corresponding data application is completed, the flexibility is high, and the intelligent contract is customized according to different application scenes.

Description

technical field [0001] The invention relates to Internet information technology, in particular to a block chain-based privacy data analysis method and a computer-readable storage medium. Background technique [0002] Blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, immutability, traceability, traceability, collective maintenance, openness and transparency. These features ensure the "honesty" and "transparency" of the blockchain, laying the foundation for creating trust in the blockchain. With the development of blockchain technology, its application scenarios are becoming more and more extensive, many of which have been gradually implemented. [0003] In the process of socialized production and life of enterprises or individuals, some data involves corporate secrets or personal privacy, which is inconvenient to be disclosed to the public. This data is again referred to as private data. In some application scenarios...

Problems solved by technology

[0004] However, due to the open and transparent nature of the blockchain, there is a risk of data leakage in the storage and transmission of data on the blockchain, which poses challenges to the user's data security.

[0005] In response to this problem, there have been some solutions in the prior art to manage data access by maintaining access control lists, or based on user attribute encryption and other technical means, but these solutions are complex to manage and cannot fundamentally solve the problem of data security. question
