Abstract

The invention provides a data processing method based on an alliance chain, a block chain node and a block chain system. The method is applied to each calculation participation node in each node of a calculation alliance chain, and comprises the following steps: loading a corresponding first algorithm container by each calculation participation node according to an algorithm address broadcasted by an initiating node in each node; performing privacy calculation and signature on the local data according to the loaded first algorithm container to generate local target data; broadcasting local target data to each node, so that each node determines final target data of each node according to the local target data of all calculation participating nodes; wherein the algorithm address is the algorithm address of any privacy algorithm inquired by the initiating node according to the algorithm directory of the algorithm alliance chain. According to the data processing method based on the alliance chain provided by the embodiment of the invention, the security and credibility of the data obtained after privacy processing can be improved.

Description

technical field [0001] This application relates to the technical field of data processing, in particular to a data processing method based on alliance chain, blockchain nodes and blockchain system. Background technique [0002] In recent years, data sovereignty has been increasingly valued, and how to complete data processing under the premise of protecting privacy has become an important research topic. Traditional privacy computing usually uses privacy computing algorithms such as federated learning, secure multi-party computing, and differential privacy to process data privately. [0003] In related technologies, each participant selects the same privacy computing framework, and completes the privacy processing of data by agreeing on specific algorithms in the framework. However, due to the variety of privacy computing algorithms and complex implementation, and the existing privacy computing is limited by the capabilities of the framework, it cannot flexibly support the ...
