[Outline of current research: Media security technology for safe and secure distribution of digital media] 

Thanks to the state-of-the-art network functions, cyberspace infrastructure has been established and more and more digital media, e.g., text, music and movies, are distributed in cyberspace. However, it is difficult to distribute high-quality and reliable digital media, because, compared with physical space, cyberspace does not provide sufficient security in areas such as copyright protection, distribution management, and authenticity assurance.

Our study aims at achieving safe and secure media distribution in cyberspace. We are seeking digital media security technology with security requirements matching those in physical space. Specifically, we are seeking

[Techniques and systems for safe and secure media distribution] 
Digital media-such as pictures, movies, and music-is being made widely available because of its advantages over analog media. However, copyright infringement, information leaks, and alteration remain issues on the digital media because it can easily be modified, copied, and sent illegally over the Internet. Thus, we are developing technology of information hiding that embeds attributes (e.g., copyright info.) into content by slightly changing its data value so that system can adequately control content flow based on the embedded information. Our goal is to establish security systems and technology for fair use of multimedia content. We establish (1) a media distribution protocol based on information hiding and cryptographic protocols, which is robust against media conversion and cryptographically safe; (2) system security that provides, in a simple configuration, copyright protection, distribution management, authenticity assurance and other security measures; and (3) fundamental technologies and system technologies that help achieve smooth digital media distribution. (Please find one of our project; Re-shooting prevention based on difference between sensory perceptions of humans and devices)

[Privacy and business processes for personalized services (joint research with University of Freiburg, Germany)] 
The objective of the proposed project is to enhance the trust model: users should control the enforcement of obligations concerning the delegation of their personal data by data providers. Service providers should be able to prove the enforcement of obligations and so to show the usage of personal data according to the Japanese Act on the Protection of Personal Information and the European Data Protection Directive. This is supposed to support the exchange of personal data between Japanese and European service providers. An information system will be developed so that users are able to check the enforcement of these obligations. The foundation for this approach is information flow control mechanisms such as modified digital watermarking schemes.

[Anonymity systems and anonymity metrics (joint research with VNU-HCM, Vietnam)] 
In online systems, such as electronic election systems, online shopping, medical consulting, or electronic mailing, it is required to provide anonymity for users. Various privacy enhancing technologies (PET) have been proposed both in theoretical models and implementations. However, new techniques and protocols are still in need for electronic transactions and it is necessary to analyze and to evaluate the anonymity level of both existing systems and new proposed systems. We therefore establish new protocols for anonymous systems in electronic transactions and to measure/evaluate anonymity of proposed systems. The proposed protocols aim to provide higher anonymity than existing ones while maintaining users' flexibility.
