  The prevalence of Closed Circuit Television (CCTV) in today's society has
given rise to an inherent asymmetry of control between the watchers and the
watched. A sense of unease relating to the unobservable observer (operator)
often leads to a lack of trust in the camera and its purpose, despite security
cameras generally being present as a protective device. In this paper, we
detail our concept of Open Circuit Television and prototype CryptoCam, a novel
system for secure sharing of video footage to individuals and potential
subjects nearby. Utilizing point-of-capture encryption and wireless transfer of
time-based access keys for footage, we have developed a system to encourage a
more open approach to information sharing and consumption. Detailing concerns
highlighted in existing literature we formalize our over-arching concept into a
framework called Open Circuit Television (OCTV). Through CryptoCam we hope to
address this asymmetry of control by providing subjects with data equity,
discoverability and oversight.
