Design of Architectures for Proximity-aware Services: Experiments in Context-based Authentication with Subjective Logic

摘要: This paper addresses the design of architectures for proximity-aware services with unobtrusive and context-based identification authentication features. A service is ''proximity-aware'' when it automatically detects presence entities in its proximity. process ''context-based'' uses contextual information to discern among different identities evaluate whether they are authentic or not. We refer an existing architecture, available our institute, where a network sensors used detect users user devices various locations building. Proximity-aware offered at intelligent coffee corners unobtrusively identified authenticated while approaching. level approaching identity calculated as overall expectation belief (i.e., trust) that (and not another) effectively standing space. use Subjective Logic theoretic framework calculations. According previous study ours, we manage each was recommender giving subjective ''opinions'' over statements concerning position users. Informally, has higher certain place more sensors-recommenders believe stands place. present comment results from array experiments show how trust can be authenticate room. perform under circumstances, namely change area room relative disposition sensors. indicate some guidelines aims maximise benefits framework.
