Context-based Authentication Service for The Mobile Office

Jiyoung Yang, Hyundong Lee, Shi-Kook Rhyoo, Mokdong Chung
2012 Journal of Korea Multimedia Society  
Most of the recent mobile office systems use a simple authentication scheme such as ID/Password. This method is easy to use, but it does not consider the user's context.  ...  Therefore, this paper proposes a context based authentication system which applies security level verification and uses fuzzy algorithm based on the importance of access authority control.  ...  We propose a method of evaluating the system validity by using the following three categories of information as shown in Fig. 1 .  ...

Towards zero-click mobile IR evaluation

Tetsuya Sakai
2012 Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '12  
In this poster, we propose two evaluation tasks for mobile information access. The first task evaluates the system's ability to guess what the user's query should be given a context ("Knowing What").  ...  We conduct a preliminary manual analysis of a mobile query log to limit the space of possible queries so as to design feasible and practical evaluation tasks.  ...  In the context of mobile IR, Jones and Brown [2] described Context-Aware Retrieval, where the system can be "interactive" (waits for the user to request information) or "proactive" (information to be  ...
