In our project we use DWT(discrete wavelet transform) based image watermarking as a category of best techniques for watermarking till date with properties of wavelets. A method and system are disclosed for inserting relationships between or among property values of certain coefficients of a transformed host image. The relationships encode the watermark information. One aspect of the present invention is to modify an STD Method to adapt it to a perceptual model simplified for the wavelet domain. Embodiments of the present invention provide digital watermarking methods that embed a digital watermark in both the low and high frequencies of an image or other production, providing a digital watermark that is resistant to a variety of attacks. The digital watermarking methods of the present invention optimize the strength of the embedded digital watermark such that it is as powerful as possible without being perceptible to the human eye. The digital watermarking methods of the present invention do this relatively quickly, in realtime, and in an automated fashion using an intelligent system, such as a neural network.
