Title:
SECURE FEATURE ENGINEERING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/177475
Kind Code:
A1
Abstract:
Provided are a secure feature engineering method and apparatus. A first device may transmit a first data set to a second device, the first data set including a ciphertext of tag information of a plurality of data objects. The second device may perform feature engineering processing on a second data set including feature data of the plurality of data objects so as to generate a subset of the second data set. The second device may generate a ciphertext subset of the tag information of the corresponding data object in the first data set according to the subset of the second data set, and send a ciphertext of the ciphertext subset to the first device. The first device can decrypt the ciphertext subset and generate statistical information, and send the statistical information to the second device. The second device may use the statistical information to calculate a feature engineering index. Further provided is a corresponding feature engineering apparatus.
