A cross-layer authentication design for secure video transportation in wireless sensor network
Ju Wang, Gregory L. Smith · International Journal of Security and Networks · 2010
Transporting video data thought a Wireless Sensor Network is inherently vulnerable to attacks due to the open nature of the physical media. To protect the authenticity of the received video data, we present a scheme that incorporates a blind video watermarking method and middleman detection algorithms to defend against correlation and middleman attacks. We uses a unique F-modulation method where each watermark bit is modulated by a local F bit to enable blind detection at the receiver side. A novel content based block selection algorithm is used to spreading the locations of marked blocks to prevent correlation attack.
