Kind Code:
A1
Abstract:
Provided in embodiments of the present invention are a data processing method and device, and an electronic apparatus. The method comprises: acquiring, on the basis of an encryption decision forest, a target leaf node matching business data, wherein the encryption decision forest comprises 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 means of homomorphic encryption algorithm; and sending, to a first apparatus, ciphertext data corresponding to the target leaf node.
