Privacy and Security in Pervasive and Ubiquitous Computing

With ubiquitous computing, individuals are always surrounded by technology, which has become an essential part of their daily routines. Ubiquitous computing, also known as pervasive computing, is a concept where computing is available anytime and anywhere. It is supported using any device, any location, and any format. With technology being intertwined in human lives, the problem arises when we start to discuss the user's privacy and security in pervasive/ubiquitous computing environments. There are many ways in which a user's privacy and security can be at risk. This paper will examine these privacy and security issues and discuss techniques that could solve these problems. Our research results show that the average of finding a pseudonym in our controlled experiment is 0.012694%. With these results, we conclude that the possibility of tracking a single pseudonym consistently in an area of a half square mile is virtually impossible.
