Data processing method and device and server

Abstract

The invention provides a data processing method and device and a server. Based on the method, a first data party holding a target model of a tree model structure comprising a plurality of model layers and a second data party holding to-be-processed target data can respond to a target processing request, and ciphertext data of the target model and ciphertext data of the target data are used as inputs respectively; and based on a preset protocol rule comprising the model layer combination calculation rule, target data processing is cooperatively performed. Therefore, on the premise of protecting the data privacy of the participant, the complexity of the processing process is effectively reduced, the target model is efficiently utilized to process the target data, and the target processing result about the target data is obtained.

Description

technical field [0001] This specification belongs to the technical field of the Internet, and in particular relates to a data processing method, device and server. Background technique [0002] In some data processing scenarios (for example, joint forecasting scenarios, etc.), there are often situations where different data parties respectively hold the forecasting model and the business data to be processed. For example, the first data party holds the prediction model, and the second data party holds the business data to be processed. In order to protect the data privacy of both parties, it is required that on the premise that the two parties cannot know the data held by the other party, corresponding processing should be carried out through cooperation, so as to call the prediction model held by the first data party to process the business held by the second data party data to get the corresponding prediction results.
