Personal information can be valuable resources for personalization of services whereas careful consideration to privacy protection is needed for personal data utilization. Once personal data is contributed, it is difficult for data contributors to control who utilizes it for what purposes. The aim of this project is to establish a computational base that collects encrypted personal information from data contributors and performs data analysis without decryption for analysts. Our system allows data contributors to control who uses his/her data for what purpose at any time after data contribution. Our technology is demonstrated by application to personalized preventive medication.
