Abstract: 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.

Keywords: correlation attacks; wireless video sensors; watermarking; protocol; cross-layer authentication; secure video transportation; wireless sensor networks; WSNs; wireless networks; middleman attacks; blind detection; block selection; security.
