INFORMATION MANAGING SYSTEM, ANONYMIZING METHOD AND STORAGE MEDIUM |
摘要 |
After anonymization of individual information such as clinical data, only the owner of a specimen data or the owner of a browsing right can identify data stored or related to it after the anonymization. Therefore, in an unlinkable anonymizing method, a uni-directional function such as a hash value calculation is applied to a combination data of related information such as an individual identifiable ID number or data, ID information and a key symbol in case of the anonymization, or a relational data such as a specimen number from only which an individual cannot be identified. A correspondence table of the anonymization number and the individual information is deleted. An estimation of an original individual or a specimen number from the anonymization number is prevented by use of uni-directional function. The access to the data after the anonymization is limited only to the owner who knows anonymization key data or the mandatory of the information.
