Transporting live Image/video data thought a Wireless Network is required in many applications (such as video wireless sensor networks). However multi-hop wireless video transportation is inherently more vulnerable against attackers due to the openness of its physical media. We present a blind video watermark scheme that is resilient against correlation attack and playback attack. Our scheme 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.
