Due to the development of computer technology and the wide use of the Internet, intelligent appliances with multimedia capability have been emerging into our daily life. Kitchen is one of the places where such intelligent appliances have been used. Since modern life style is driving people spending less time on cooking healthy food at home, an enjoyable and healthy life style can be assisted with an intelligent kitchenware such as a smart fridge. In this paper we introduce a novel application for a smart fridge with intelligent multimedia capability. It is designed for managing items stored in it and advising its users with cooking methods depending on what kind of food is stored. It can also perform other functions such as dietary control, nutrition monitoring, eating habit analysis, etc. We are confident that such a smart fridge will be an important component in future smart homes.
The emergence of Internet of Things (IoT) brings tremendous benefits and opportunities for individuals and businesses. However, there exist several challenges that need to be addressed before a full realization of IoT can be achieved. Fundamentally, IoT enables constant transfer and sharing of data between several "things" (i.e. humans and objects) in order to achieve particular objectives. In such sharing environments, security and privacy of data and messages become important. Authentication, authorization. access control, non-repudiation are important to ensure secure communication in an IoT environment. The lack of computing resources (such as processing power, storage, etc.) and ad-hoc nature of such networks requires researcher to rethink existing techniques to adopt to such environments. In this paper, we propose a framework for authentication, authorization and access control for an IoT environment using capability tokens, PKI and encryption which aims to use minimal computing resources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
