“…So, to maintain the required quality of watermarked image it is necessary to select a suitable scaling factor for the algorithm. The resultant image of this embedding process is known as watermarked image and this image gets floated over the social networks where the malicious attackers try to modify it using image processing and geometrics tools available [4][5][6][7]. The attacked watermarked image then becomes the input to the extractor unit, where the owner can claim his copyright.…”

Abstract: Digital watermarking has emerged as a potential solution to copyright-related issues of digital data. A novel, highly secure robust digital watermarking method using DWT-SVD is presented in this paper. Instead of using the conventional watermark embedding process where the watermark gets embedded over the entire host image, the coefficients for embedding the watermark inside the host image has been identified in this proposed method. Such selection of pixels used for insertion of watermark makes this algorithm highly secure, robust, and imperceptible. The experimental results demonstrate the efficiency of the proposed method in aspects of high robustness and good imperceptibility.

“…Watermarking techniques are categorized as robust, fragile, and hybrid according to the purpose they serves. Robust watermarks are used for copy protection and copyright protection [ 6 , 7 ] as they are resistant to image processing operations like rotation, scaling, cropping, and so forth. Robust watermarking methods assume the transmission channel as lossless and hence embedding is done in either lossless or lossy environment.…”

Providing authentication and integrity in medical images is a problem and this work proposes a new blind fragile region based lossless reversible watermarking technique to improve trustworthiness of medical images. The proposed technique embeds the watermark using a reversible least significant bit embedding scheme. The scheme combines hashing, compression, and digital signature techniques to create a content dependent watermark making use of compressed region of interest (ROI) for recovery of ROI as reported in literature. The experiments were carried out to prove the performance of the scheme and its assessment reveals that ROI is extracted in an intact manner and PSNR values obtained lead to realization that the presented scheme offers greater protection for health imageries.
