Appling sensitive technique to hid digital watermarking in still images

Digital watermarking is a new field of security, it is important in verifying from widespread digital information transmission techniques, it protects digital still images, video, or sounds from piracy.Digital watermarking gives real owner the ability to check if a file is an unauthorized copy or if it has been modified without authentication.Within development of digital watermarking technique, methods of watermarking attacks have been developed for deleting or modifying to improve illegal copying. In this research, new sensitive technique is developed for hiding digital watermarking into a still image in a way that satisfied randomly hiding which includes every parts of image, to protect it from attacking.
