A Framework for User Privacy Protection Using Trusted Programs
Kenichi Takahashi,Zhaoyu Liu,Kouichi Sakurai,Makoto Amamiya 보안공학연구지원센터 2007 International Journal of Security and Its Applicat Vol.1 No.2
The evolution of mobile technologies enables us to realize ubiquitous computing environments. In such environments, a user’s mobile terminal manages the sensitive information and assists in various activities based on the user’s information. At the same time, information leakage will become a serious social problem. In this paper, we propose a framework to protect the sensitive information of users in a manner they consider safe. In the framework, the user provides a trusted program that implements the manner he/she considers safe. The information recipient accesses user’s sensitive information through this trusted program. In this manner, the user can protect his/her sensitive information. However, there exist several challenges in the realization of this framework. In this paper, we propose a method for generating a trusted program and discuss the solutions to other challenges.
