PRIVACY PROTECTION-TYPE DATA PROVIDING SYSTEM

摘要

An information providing apparatus for collecting data including personal information and distributing the data to a user terminal performs anonymization processing for converting data, which an individual who is an owner of personal information allows to use, into data with which the individual cannot be identified using multiple parameters, thus generating multiple anonymized data protecting the, privacy of the individual. Since each of the anonymized data is anonymized using a different parameter, the amount of information of each of the anonymized data is different. Then, when a request is received from a user terminal, anonymized data that can be provided to the user are identified from among multiple generated anonymized data on the basis of the reliability of the user who uses the user terminal.
