Abstract: A methodology for comparing robustness of spatial domain and transform domain watermarking techniques is proposed. The techniques used in the spatial domain are the least significant bit method and the transform domain technique used is the discrete cosine transforms based method. The techniques are compared on the basis of their susceptibilities to various types of noises which a work of digital media undergoes during intentional or unintentional modification in the real world. The recovery of watermarks in such simulated conditions as addition of Gaussian noise , salt & pepper noise, JPEG compression leads us to draw conclusions about how these techniques fare in the actual world. Moreover, the noise levels have been varied so as to elicit the threshold where even an otherwise robust technique fails.
