PERFORMING DATA PROCESSING BASED ON DECISION TREE

Abstract:

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for data processing. One of the methods includes: determining a set of values in the set of splitting criteria based on the service data, wherein the set of values indicate whether the set of splitting criteria of the burst node are met; encrypting the set of values using a random number, to obtain cyphertext of the set of values; executing a secure data selection algorithm by using the ciphertext of the set of values as input; and executing a secure multi-party computation algorithm by using the random number as input to obtain a prediction result of a decision forest.
