TrustCAM: Security and Privacy-Protection for an Embedded Smart Camera Based on Trusted Computing
Thomas Winkler, Bernhard Rinner · 2010
Security and privacy protection are critical issues for public acceptance of camera networks. Smart cameras, with onboard image processing, can be used to identify and remove privacy sensitive image regions. Existing approaches, however, only address isolated aspects without considering the integration with established security technologies and the underlying platform. This work tries to fill this gap and presents TrustCAM, a security-enhanced smart camera. Based on Trusted Computing, we realize integrity protection, authenticity and confidentiality of image data. Multiple levels of privacy protection, together with access control, are supported. Impact on overall system performance is evaluated on a real prototype implementation.
