Security For Whom?

Pervasive computing will introduce hundreds of computing devices per user. This change is of such magnitude that it is qualitative as well as quantitative. Old solutions may not scale when the size of the problem grows by such a factor—passwords, for example, will no longer be a suitable user authentication method. In this paper we examine new security issues for pervasive computing including authentication, biometrics and digital rights management. But the potential impact of pervasive computing on society is such that we have a responsibility to look further than just the technical issues.
