Data processing method and related equipment

The invention provides a data processing method and related equipment, and the method comprises the steps: receiving a data processing request sent by a task initiator, the data processing request being used for requesting privacy calculation for target source data; querying the processing authority of the task initiator for the target source data from the plurality of block chain nodes, and calling the privacy computing service to process the target source data in response to the processing authority of the task initiator for the target source data; and storing intermediate process data and processing record data generated by processing the target source data by the privacy computing service in a plurality of block chain nodes. According to the method, the block chain technology and the privacy computing technology are combined, data credible storage and management of the privacy computing in the whole life cycle before, during and after the event can be achieved, and then data safety guarantee in the data p
