TrustCAM: Security and Privacy-Protection for an Embedded Smart Camera Based on Trusted Computing

Security and privacy protection are critical issues forpublic acceptance of camera networks. Smart cameras,with onboard image processing, can be used to identifyand remove privacy sensitive image regions. Existing approaches,however, only address isolated aspects withoutconsidering the integration with established security technologiesand the underlying platform. This work tries to fillthis gap and presents TrustCAM, a security-enhanced smartcamera. Based on Trusted Computing, we realize integrityprotection, authenticity and confidentiality of image data.Multiple levels of privacy protection, together with accesscontrol, are supported. Impact on overall system performanceis evaluated on a real prototype implementation.
