Sensors and in particular cameras have found their way into many parts of our daily lives. While monitoring public places is still a common use case for camera systems, applications in private environments are emerging. The ever growing number of cameras raises important questions concerning security and privacy. \u201cOur approach to tackle these questions is to protect all sensitive data before it leaves the camera,\u201d explains Bernhard Rinner. \u201cWe exploit the available computing resources of modern camera systems for onboard privacy protection and data security and do not rely on pure software solutions. We have successfully demonstrated this approach on several prototypes.\u201d<\/p>\n\n\n\n

The key idea is to \u201cprotect\u201d access to the image sensor and encapsulate dedicated security and privacy functionality in a TrustEYE<\/em>\u2014a secure sensing unit embedded on the smart camera. The TrustEYE has exclusive access to the image sensor\u2019s raw data. It separates sensitive from non-sensitive data by applying dedicated image analysis and ensures that only non-sensitive data is made available to the camera host system.<\/p>\n<\/div><\/div>\n\n\n\n

\u201cIn another prototype, we use modern hybrid ARM\/FPGA system-on-chip solutions to provide security and high speed image analysis functions,\u201d Ihtesham Haider points out. \u201cWe exploit inherent hardware properties in the form of physical unclonable functions<\/em> to realize high levels of security without requiring additional specialized hardware for cryptographic functions.\u201d<\/p>\n<\/div><\/div>\n\n\n\n
