Ubiquitous Computing Environment Threats and Defensive Measures

Ubiquitous Computing is considered an information technology that fuses real space and cyber space based on the networks among existing things in the real world. Advances in ubiquitous have been topics in so much researches. In this paper, we analyze security threats of mobile computing devices with an application of ubiquitous computing and we suggest their countermeasures in technical, manageable, and physical aspects.
