Our Research Ubiquitous Network Security using Multi-agent (Researcher: Ken-ichi Takahashi) l By using Ubiquitous Computing Environments, many eservices are deployed. l Various services will require user’s information for confirming the user can receive the services. HOWEVER Only habitants can use it l In communicating user with 　service systems, there is a risk of compromis- name right ing privacy THEREFORE l We propose new multi-agent architecture for privacy protection ! 12/6/2020 Are you more than 20 years old? money : A User Do you have the right of copying these papers? 13 Services

Our Research Group Key Management Researcher: Ryuzou Nishi l In Services based on Broadcasting, how can we send the services to only legitimate users? We distribute decrypting key for the users! HOWEVER l When new member joins, or current member leaves the users’ group, how can we renew a key efficiently? Decrypt THEREFORE l We propose efficient Group Key Management scheme. Decrypt 12/6/2020 14 Decrypt

Our Research Biometric Authentication on the Internet Researcher: Yoshifumi Ueshige u. Biometrics is available for identification of legitimate users. ØOn-line Banking, other e-business 　　 　　　　Biometrics on the Internet for On-line Services! HOWEVER u. Biometric information includes a significant PRIVACY!! Threats THEREFORE u. We propose new Technique of Biometric Information Protection! 12/6/2020 INTERNET Biometric Authentication Client Services 15 Server
