Secure embedded visual sensing in end-user applications with TrustEYE.M4

Sensor networks are becoming popular for applications in private environments such as home monitoring, baby and child monitoring or ambient assisted living. What is often overlooked is the fact that data collected in this context can be very privacy sensitive. This is especially true if images or videos are captured and streamed into the cloud. This work presents a visual sensor network device along with a secure data delivery and archiving solution using untrusted public cloud storage services.

This is achieved by extending the sensing device with a local communication interface for establishing a secure link between data producer and consumer. Our custom-designed TrustEYE.M4 prototype implements secure data delivery and uses Near Field Communication (NFC) for the initialization of the communication link. The presented solution is not limited to visual sensing applications but can be applied to a wide range of pervasive sensing and data delivery scenarios.
