Block chain and security multi-party technology combined content awareness method and system

Abstract

The invention provides a blockchain and security multi-party technology combined content awareness method, which belongs to the field of financial data, can be widely applied to financial service scenes such as financial security data sharing and the like, and comprises the following steps: acquiring a deployment request of a smart contract, and assembling a deployment message to all blockchain nodes to broadcast; each block chain node analyzes the deployment message and deploys the smart contract; issuing a multi-party security computing transaction request, assembling a transaction message, and broadcasting the transaction message to all block chain nodes; each block chain node analyzes the transaction message and performs joint calculation on encrypted data in the transaction message; and the smart contract on each block chain node verifies a multi-party security computing transaction result through a block chain consensus mechanism and evaluates a similarity result. On the basis of a block chain and multi-party security computing framework, a semantic perceptual hash algorithm is creatively embedded into the block chain and multi-party security computing framework, and the problems of digital file content tracking and operation are effectively solved.

Description

technical field [0001] The invention relates to the technical field of financial data, in particular to a content perception method and system combining blockchain and secure multi-party technology. Background technique [0002] In the traditional distributed system, all parties involved in the system need to exchange data around the regional central system. All business processes between institutions in the system must be processed by the central system. Data processing is subject to the processing time of the central system. The timeliness is low; in addition, each participant in the system is unwilling to share internal data out of consideration of their own data privacy, business interests, etc., which makes it easy to form data islands in a multi-centralized operating system, and it is difficult to form cross-subject and cross-border data. The joint operation mode of the scene, the business development mode is limited. [0003] The decentralization, non-tampering, and ...
