PRNU-based source identification for network video surveillance system

摘要

Photo response non-uniformity (PRNU) noise has been proven instrumental for camera source identification in image forensics. The paper proposes a signal-based detection system using PRNU for source verification in video surveillance systems. The effects of different aspects such as video resolutions, frame types and environmental conditions on the accuracy and reliability of the system have been tested. Our results show that the signal-based approach is effective to verify the video source.
