DATA-BASED PREDICTION RESULTS USING DECISION FORESTS

摘要

Implementations of the present specification provide a data processing method and apparatus, and an electronic device. The method includes the following: obtaining a target leaf node that matches business data based on an encryption decision forest, where the encryption decision forest includes at least one decision tree, a splitting node of the decision tree corresponds to plaintext data of a splitting condition, a leaf node of the decision tree corresponds to ciphertext data of a leaf value, and the ciphertext data is obtained by encrypting the leaf value by a homomorphic encryption algorithm; and sending ciphertext data corresponding to the target leaf node to a first device.
