Embedding Technique of Fragile Watermark Based on Neural Network
Tao Gu · Journal of North China Institute of Science and Technology · 2004
It is proposed a neural network algorithm which embedded fragile watermark into a color image. The watermark can be retrieved without knowing the original image. Meanwhile, besides telling you whether an image has been tampered, the fragile watermark could as well, reflect the distortion status in spatial domain of the image.
