Abstract:
(EN) Disclosed is a method for encrypting data, comprising: generating an (N*M)-dimensional target matrix on the basis of N data samples and data features of M dimensions respectively corresponding to the N data samples; performing encryption calculation on the target matrix on the basis of a PCA algorithm to obtain an encrypted (N*K)-dimensional encryption matrix; and transmitting the encryption matrix to a modeling server, such that the modeling server uses the encryption matrix as a training sample to train a machine learning model.
(FR) L'invention concerne un procédé de chiffrement de données, comprenant: la génération d'une matrice cible (N*M)-dimensionnelle sur la base de N échantillons de données et de caractéristiques de données de M dimensions correspondant respectivement aux N échantillons de données; effectuer un calcul de chiffrement sur la matrice cible sur la base d'un algorithme PCA pour obtenir une matrice de chiffrement à (N*K) dimensions chiffrée; et transmettre la matrice de chiffrement à un serveur de modélisation, de telle sorte que le serveur de modélisation utilise la matrice de chiffrement comme échantillon d'apprentissage pour entraîner un modèle d'apprentissage machine.
(ZH) 公开一种数据加密方法,包括:基于N条数据样本以及分别对应于所述N条数据样本的M个维度的数据特征生成N*M维的目标矩阵;基于PCA算法对所述目标矩阵进行加密计算,得到加密后的N*K维的加密矩阵;将所述加密矩阵传输至建模服务端,由所述建模服务端将所述加密矩阵作为训练样本训练机器学习模型。
