Classification of watermarking methods based on watermarking approaches

Video watermarking is the approach of adding insensible data to video content in order to protect the owner's right. One of the main important issues in watermarking operation is the watermarking robustness. The basic requirement in watermarking is resisting in front of distortion and initial attacks, which is commonly examined based on the data processing standards. Many methods have been proposed in the field of video watermarking that are resistant to certain attacks, therefore some attacks can break the watermark. So, the correct identification of methods and knowing the strength and weakness of each method lead to propose appropriate solution in order to reduce the effects of attacks with presenting secure algorithm in video watermarking.
