Digital watermarking has emerged as a potentially effective tool for multimedia copyright protection, authentication, and tamper-proofing . Robustness of watermarking is one of the key issues for some applications, such as intellectual property protection and covert communication. A serious problem constraining some practical exploitations of watermarking technology is the insufficient robustness of existing watermarking algorithms to geometrical distortions such as translation, rotation, scaling, cropping, change of aspect ratio, and shearing.
