Information Hiding
4:00 pm, Wean Hall 7500
3:45 pm - Refreshments Outside the Auditorium
ABSTRACT
Over the last five years, techniques for hiding information have
become a rapidly growing research topic. Its better known aspects
range from inserting imperceptible copyright marks in digital audio
and video, through auctions and elections, to de-identifying medical
records for use in research. As we explore these applications, it
becomes clear that the traditional protection goals of
`confidentiality, availability and integrity' are insufficient.
In this talk, I will discuss the role of anonymity in computer security. Anonymity mechanisms allow us to construct networks and file systems that are resistent to selective denial of service attacks, or which let their owners plausibly deny their existence (thus providing some protection against coercion). They can help us to meet protection goals such as personal privacy, location security and plausible deniability.
