Abstract :
A fragile watermarking scheme based on integer wavelet transform and chaos sequence is proposed in this paper. The novel watermarking scheme uses the quad tree structures received by the wavelet decomposition and chaos sequences to choose locations where are embedded the watermark information. The scheme has high signal-to-noise because it only embed watermark into the latest bit of node. It is suitable for medical image and it is also easy to implement on hardware. The difference between the scheme and other schemes based on integer wavelet transform is that we embed watermark on the coefficients of integer wavelet transform separately.
