Media spaces integrate audio, video, and computing systems for the purpose of remote collaboration and awareness, frequently between people engaged in a cooperative task. Technological advances have made these systems feasible using desktop computers and broadband, digital networks. Using a media space over a shared network requires that numerous security and privacy issues be addressed. One advantage of digital media spaces is that properties of the media space can be manipulated so that users feel more comfortable with the technology. This paper details cryptographic techniques which can be used to create a secure and usable media space. This paper also explains the properties of a user interface which would enable users to ensure their level of privacy. This work also details two interface designs which provide users with sophisticated, flexible control of their media space without requiring a detailed understanding of the underlying cryptographic mechanisms.
