AI Technical Summary
Technical Problem
Conventional differential privacy methods apply the same noise value to all data, leading to excessive noise in less sparse data, distorting statistical characteristics and reducing data usability.
Method used
A statistical data providing device that differentially applies noise values based on the sparsity of raw data to maintain statistical characteristics and satisfy a preset security level.
Benefits of technology
Generates query data that preserves the statistical characteristics of the raw dataset while ensuring differential privacy, enhancing data usability.

Abstract
A statistical data providing device according to the present invention includes a memory storing a data providing program that provides a response value corresponding to a query; and a processor that executes the data providing program, wherein the data providing program receives a query, generates a raw response value corresponding to the query, calculates the sparsity of the raw data from the raw response value, optimizes a noise value for the raw data based on the sparsity and optimization conditions, and generates a query response value by applying an optimized noise value corresponding to the sparsity to the raw data.
