Abstract
Recently, according to the number of Internet in widely use and the development of the related application, the distribution and use of multimedia contents, such as digital images, are very easy. Since these can modify as easy as use, multimedia contents need newly compressed JPEG 2000 and digital watermarking technique because of its enormous amount of information. To protect the digital image in real-time, this paper proposes two methods that Dual Watermarking Method (DWM) based JPEG 2000 and performing JPEG 2000 and watermarking synchronously. DWM consists of the robust and fragile watermarking. Also, in DWM, watermarks are carefully embedded avoiding the areas of Region Of Interest (ROI) and the edge of the digital image to protect the integrity of it. In performing JPEG 2000 and watermarking, it takes considerably less time to do JPEG 2000 and watermarking than when they are done separately. Based on the experimental results, it takes 0.72 second for JPEG 2000 and watermarking, and 1.11 second when they are done separately.
