- W4281721627 abstract "Now-a-day’s every field focuses on digital content. Information is handled on the internet in digital form. Illegal copyright material must be restricted to prevent digital information from being copied. A better answer to this problem is digital watermarking. Digital watermarking is a copyright-protection technique that involves obscuring a picture. The suggested work is primarily concerned with the frequency domain, and it employs a discrete cosine transform (DCT) technique to transform the original image (cover image) into the frequency domain to add a watermark. DCT algorithm increases the speed of the process of watermarking the image. The algorithm performs picture decoding, image processing, watermarking, and decoding of the watermarked image, as well as applying a frequency transformation on the host data to embed a watermark. The transform coefficients and possible picture transformations are then modified. Embedding is done at the sender side and extraction is done at the receiver side. This algorithm also supports secure and faster transmission of images to the receiver. In the future, watermarking applications will include secure extensions, and digital watermarks must meet certain requirements such as integrity, robustness, and complexity." @default.
