摘要
Abstract
To make vector quantization (VQ) attack impossible without the need of any unique keys or image indexes, a moment invariants based fragile image watermarking scheme is proposed. Image moment invariants are extracted as the index to generate the image-dependent watermark, which is unknown to the attacker and different for different images. Encoding with the output of hash function of the seven most significant bits stream serial of image blocks, watermark is embedded into the LSB of image blocks under the consideration of security and localization. Experimental results demonstrate that our algorithm can detect even one bit image alteration with graceful localization, and successfully resist vector quantization attack simultaneously without the need of any unique keys or image indexes.关键词
