Title:
DATA DESENSITIZATION METHOD, DATA DESENSITIZATION APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/065632
Kind Code:
A1
Abstract:
The present application relates to the field of artificial intelligence, in particular to a data desensitization method, a data desensitization apparatus, a device, and a storage medium. The method comprises: obtaining user data, and performing information identification on the user data on the basis of a pre-trained key information identification model to obtain key information; preprocessing the key information to obtain discrete variables corresponding to the key information, the preprocessing comprising data discretization processing or data normalization processing; performing conditional random sampling processing on the discrete variables on the basis of a conditional loss function to obtain a conditional embedding vector and a hidden vector, and splicing the conditional embedding vector and the hidden vector to obtain a spliced vector; and inputting the spliced vector into a pre-trained generator for desensitization processing to obtain desensitized data. Therefore, desensitized data cannot be easily reversely cracked, thereby ensuring that privacy data will not be leaked, and improving the security of the desensitized data.
