The project examines how cryptographic systems can be used to
introduce a level of privacy in video surveilled areas. Digital video
cameras are getting more and more numerous and since several years
cameras with builtin TCP/IP connectivity are available. Combined with
radio frequency based identification mechanisms it will eventually be
possible to completely surveille a person. Especially storing the
information gathered and semi-automatically retrieving of this data
will be possible. The individual will not have much control over what
happens with the video footage taken of him.
In this context the project uses state of the art cryptographic
technologies to enable a person to control access to her video. As
default any part of the video showing a specific person is obscured.
However the video of the person is still available but protected by
this very persons personal (cryptographic) key. The person herself can
grant or revoke access to this protected video.
Besides building a prototype installation for such a system the
research focuses on the evolution of public and private spaces in
relation to changing surveillance technologies. Special interest is
given to the evolving technology of IP based building automation and
it's consequences for surveillance systems.
