Abstract
This paper presents a robust watermarking technique using biorthogonal wavelet transform. In proposed method the blue channel of the color host image is selected for embedding watermark because it is more resistant to changes compared to red and green channels. The blue channel is decomposed into n levels using biorthogonal wavelet transform because biorthogonal wavelet transform is an invertible transform and has the property of exact reconstruction and smoothness. This method is shown to be robust against many signal processing operations as well as geometrical attacks.
