Outline of Final Research Achievements

A user authentication service was added to the new JPKI. However, it is pointed out that there is a possibility of invasion of privacy by using one public key certificate, and the possibility that data rewriting etc. at the time of using the service may occur due to malware installed to a web browser. In my research, I proposed a mechanism that service provider issue an individual ID numbers that identify users who take into consideration the privacy of users and protection method of services using JPKI from malware etc..
