Abstract

The WCAM project aims to provide an integrated system for secure delivery of video surveillance data over a wireless network, while remaining scalable and robust to transmission errors. To achieve these goals, the content is encoded in Motion-JPEG2000 and streamed with a specific RTP protocol encapsulation to prevent the loss of packets containing the most essential data. Protection of the video data is performed at content level using the standardized JPSEC syntax, along with flexible encryption of quality layers or resolution levels. This selective encryption respects the JPEG2000 structure of the stream, not only ensuring end-to-end ciphered delivery, but also enabling dynamic content adaptation within the wireless network (quality of service, adaptation to the user's terminal). Some DRM modules from OPENSDRM platform will be added to manage all authenticated peers on the WLAN (from end-users to cameras), as well as to manage the rights to display conditionally the video data. This whole integrated architecture addresses several security problems such as data encryption, integrity and access control. Using several protection layers, the level of confidentiality can depend on both the content characteristics and the user rights, thus also addressing the critical issue of privacy.
