METHOD AND DEVICE FOR GENERATING RANDOM NOISE DATA PRESERVING THE CORRELATION ON PRIVACY PRESERVING TIME-SERIES DATABASES

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a privacy protection technique for time series data, and more particularly, to a random noise generation method for time series data that preserves not only privacy protection but also correlation. According to the present invention, it is possible to provide a user with a random noise disturbance technique that maintains correlation with time series data as well as privacy protection.
