Digital watermarking is an effective means for copyright protection or covert communication in the research field of information security. By using watermarking, the watermark bits are hidden into the multimedia content with the designed algorithm. And the watermarked contents, or the watermarked image in this paper, look almost identical to its original counterpart, while it still retains the capability...
Digital watermarking, in conjunction with cryptography, is one of the two major categories for information security. Unlike cryptography that the encrypted information represents like noisy patterns, by using watermarking, the watermarked contents look almost identical to its original counterpart, while it still retains the capability to counteract intentional signal processing by others and keeps...
In this paper, we propose a practical scheme for privacy protection and authentication of medical images with the aid of EXIF metadata and associated records of the patients. By using watermarking, the goals mentioned above can be reached. Application for robust watermarking is one of the major branches in digital rights management (DRM) systems. With robust watermarking, it generally alters selected...
In this paper, we propose a practical scheme for copyright protection of images with the aid of EXIF metadata and error control codes. Application for robust watermarking is one of the major branches in digital rights management (DRM) systems and digital forensics. By use of robust watermarking, it generally alters selected coefficients in the transform domain to accomplish the embedding process....
In this paper, we propose an application of robust watermarking with the aid of EXIF metadata in digital images. Application for robust watermarking is one of the major branches in digital rights management (DRM) systems. Furthermore, implementation schemes for robust watermarking generally alter selected pixels in the spatial domain, or corresponding coefficients in the transform domain, to accomplish...
Application for robust watermarking is one of the major branches in digital rights management (DRM) systems and related researches. Based on existing metrics to evaluate the applicability of robust watermarking, it is generally agreed that three metrics, including the quality of watermarked contents, the survivability of extracted watermark after intentional or unintentional attacks, and the number...
