A Study on a Structure of Anshin about Information Security

Abstract

In this research, we propose a quantitative model of evaluating security systems in terms of sense of security. This paper starts with our original Anshin evaluation model and reports on its verification. We conducted a questionnaire survey about sense of security to make a statistical survey using factor analysis. Factor analysis showed following factors; 1) trust and security by user expectation, 2) satisfaction of user interface, and 3) understanding of risk and threat by user experience and prior knowledge. In terms of factor analysis, this survey showed that theoretical three factors in the structure of a sense of security were significant statistically. Future works are needed to discuss about some quantitative methods to evaluate for sense of security.
