In this study, the authors propose a novel technique for medical image watermark detection using the concept of the fractional differentiator (FD). The feature of FD as a non‐linear high‐pass filter helps in watermark detection. In the region of non‐interest, the watermark image has been added in a mid‐band frequency range of the discrete cosine transform coefficients of 8×8 different blocks by generating direct spread spectrum sequence. Their scheme produces noise‐free watermarked medical images. Furthermore, they derive the test statistics of the proposed detector, which is characterised by the fractional order q. The average errors in pixels (PEs), peak‐signal‐to‐noise ratio (PSNR), structural similarity index (SSIM) and cross‐correlation coefficient (CC) have been used to quantify the capability of the proposed technique over some state‐of‐the‐art techniques. The proposed technique shows that at a particular value of fractional order q, there is a significant reduction in average PEs. It causes an increment in PSNR, SSIM and CC. The proposed technique is tested on a large number of medical images and it is found that their proposed technique works better or comparable with other state‐of‐the‐art techniques.

“…However, the major limitations regarding this technique are imperceptibility and computational complexity. Ghadi et al [14] proposed an imperceptible and robust medical image watermarking technique based on the Jacobian matrix. The major issue with this technique is the high computational complexity.…”

“…At present, the studies on zero-watermarking are mostly concentrated in the image field. Ghadi et al [12] used the Jacobian matrix model and Jumana et al [13] used the genetic algorithm (GA) to construct zero-watermarks. To improve the security, many algorithms introduced visual cryptography (VC) to zero-watermarking technology [14]- [16].…”

“…Since each carrier generates its own unique zero-watermark, an intellectual property library must be established to store the zero-watermarks. To date, zero-watermarking technology has been applied to copyright protection in many fields, such as text [10], audio [11], image [12]- [19], video [20]- [24], relational databases [25], and sharing models in cooperative drive engineering [26].…”

With the rampancy of pirated videos, video watermarking for copyright protection has become a widely researched topic. In this paper, zero-watermarking is applied to videos for the first time to resist high efficiency video coding compression, which can improve the robustness of the watermarking algorithm and ensure the videos' quality. A robust video zero-watermarking algorithm based on the discrete wavelet transform, the all phase biorthogonal transform, and singular value decomposition is proposed. Utilizing the properties of hybrid transforms, robust features can be extracted from videos, and robust zero-watermarks can be constructed. Experimental results demonstrate that the proposed algorithm has strong robustness to high efficiency video coding compression attacks with different quantization parameters. In addition, the algorithm can also resist common image processing attacks, geometric attacks, frame-based attacks, and hybrid attacks. Compared with existing video watermarking algorithms, the proposed algorithm can more accurately and completely reconstruct watermark images.INDEX TERMS Video signal processing, watermarking, video watermarking, zero-watermarking, copyright protection, robustness, high efficiency video coding, discrete wavelet transform, all phase biorthogonal transform, singular value decomposition.

“…Therefore, there is inevitably a contradiction between imperceptibility and robustness of the watermark. The traditional watermarking methods are usually limited for medical images [32][33][34] and remote-sensing images [35] which require low distortion and high resolution.…”

A Novel Zero-Watermarking Scheme Based on Variable Parameter Chaotic Mapping in NSPD-DCT Domain

et al. 2020

In this paper, a novel image zero-watermarking scheme against rotation attacks is proposed based on nonsubsampled pyramid decomposition (NSPD) and discrete cosine transform (DCT). It utilizes the intrinsic characteristics of NSPD and DCT to extract the robust feature of an image as the original zero-watermark. To increase the security of the proposed scheme, a variable parameter chaotic mapping (VPCM) is designed for the processes of watermark encryption and robust feature extraction. Firstly, the host gray-scale image is decomposed by NSPD, and the low-frequency sub-band image is divided into nonoverlapping blocks. After the blocks are transformed by DCT, the signs of the first AC coefficients from all the blocks are used to construct a binary feature image. Then an exclusive-or operation is performed between the binary feature image and the encrypted watermark image to obtain the verification zero-watermark image. Furthermore, a method against arbitrary rotation attacks is employed to improve the robustness of the scheme against geometric attacks. The experimental results demonstrate that the proposed scheme is highly robust against various image processing attacks such as filtering, JPEG compression, scaling, translation, rotation and Checkmark attacks.
