University-industry collaboration networks in the information security field in Japan: problems and a particular success

Promotion of university-industry interaction has become a key topic at many levels in Japan to reform the social infrastructure. On the other hand, information security is the key to develop IT social network. In this context, what is the state of university-industry research collaboration in the information-security field in Japan? Our preliminary bibliometric analysis reported in IEMC2003 embarked on answering this question and gave a conclusion that inter-sector collaboration in the information-security field in Japan is underdeveloped. This article shows two more empirical supports for the conclusion; one uses a patent survey in this particular field in Japan, and the other is a research-network analysis confined to the major players found in the bibliometric analysis. We hope that these series of reports and methodologies used there will open the door to empirical analyses of collaboration "in a particular field in a particular country".
