STATISTICAL PROCESSING METHOD AND SYSTEM, AND DATA PROVIDING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain useful statistic data without leaking personal information of a user even if disturbing data is intercepted and without using large cost nor labor for privacy protection.

SOLUTION: Original data generated by a data providing device (1) on the basis of a user signal (5) is converted into disturbing data. Processing for the conversion includes a random step for preventing the disturbing data from being restored to the original data. The disturbing data is transmitted to an external statistical processor (12), and statistical processing for eliminating the effect of the random step is performed.
