Abstract

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.
TrustCAM:基于可信计算的嵌入式智能摄像头的安全与隐私保护
安全和隐私保护是公众接受摄像机网络的关键问题。带有机载图像处理功能的智能摄像头可用于识别和删除隐私敏感的图像区域。然而,现有的方法只处理孤立的方面,而没有考虑与已建立的安全技术和底层平台的集成。这项工作试图填补这一空白,并提出TrustCAM,一个安全增强的智能相机。基于可信计算,实现了图像数据的完整性保护、真实性和保密性。支持多级隐私保护以及访问控制。对整体系统性能的影响是在一个真实的原型实现上评估的。
