“…However, for a VCLW scheme, the security claiming robustness is meaningful if it meets Kerckhoffs's principle. Further, if the rate of false positive [26] doesn't exceed limit. Among all the seven schemes, Hwang's and Huo's schemes resulted in high false positive rates, indicating that these schemes are insecure as they result in high false positives.…”

Abstract. Digital technology has resulted in a cost effective and easy means for storage and communication of the multimedia data, which can also be easily downloadable and reproducible. Hence, there is a growing need for techniques that identify the right owner of Intellectual Property (IP). Visual Cryptography based Lossless Watermarking (VCLW) techniques are hybrid schemes that are now being developed as a potential replacement for conventional watermarking systems as they are effective in resolving existing tradeoff among the requirements. This paper presents theoretical analysis of spatial domain VCLW techniques and performs practical performance analysis, to identify gaps. These hybrid techniques offer promising quality of target image after watermarking; there are still a number of challenges associated such as security, robustness, pixel expansion, complexity, image formats etc. Among multiple requirements, achieving fewer rates of false positives is identified as fundamental requirement in order to discourage malicious owners and to protect Intellectual Property. The analysis of comparative results shows that with the existing techniques, the false positive rate could not reach 10 −6 , which is the maximum limit suggested by Cox et al. for watermarking. This is due to the unique security challenge called C 3 rule that involves the design of code tables, selection of features, thresholds and combination functions. It is concluded that in the applications where the images to be protected are very sensitive such as military, medical and satellite images, VCLW techniques can be a potential replacement for conventional watermarking systems, given that the algorithms fills the important gaps.

“…According to Borra et al [25], color images are used in different social media sites, including Instagram, WhatsApp, and Facebook. These images are moved from one server, network, or computer to another via open networks like wireless networks and the internet, in which they can face different attacks and manipulations [26], [27]. In such circumstances, different techniques for securing color images have been proposed; for example, Phadikar et al [28], put forward blind watermarking techniques based on wavelet transform for color image security.…”

In this modern era, it has become much simpler to replicate, sell, and copy the copyright owners' works without their permission as a result of the expansion of digitalization, and it is difficult to identify such violations, posing a threat to the creators' and copyright owners' rights. For many years, the internet has been regarded as one of the most serious threats to copyright, and the content available has varying levels of copyright protection. On the internet, there are numerous copyrighted works, including e-books, movies, news, and so on. Therefore, by using watermarking and steganography techniques, these issues can be solved, which are based on the author's signature information or logo. This paper concluded that the techniques of discrete cosine transform (DCT), discrete wavelet transform (DWT), one-time pad (OTP), and playfair are highly effective when used together to watermark an image or embed a secret message, our lab results validate that our algorithm scheme is robust against several sets of attacks, where the algorithm was assessed by computation of many evaluation metrics such as mean square error (MSE), signal-to-noise ratio (SNR), and peak signal-to-noise ratio (PSNR).

“…In these framework, since the detector or the decoder may not find the same locations due to the changes after recompression or imposed attacks, they used a location map or an embedding position template by private key describing embedding location which is used to find the specified locations where the watermark embeds. However, these locations are vulnerable to be identified by attackers [37], [38]. Thus, the security issue is the major problem in these methods [39], [40].…”

A Compressed-Domain Robust Video Watermarking Against Recompression Attack

et al. 2021

With the development of communication networks and the widespread use of mobile terminals, videos are increasingly shared and distributed among mobile users. During the process, the video is recompressed to a certain file size on the sending side and sent to the receiving side via the server. This makes robust video watermark with low complexity to resist recompression attacks become an important issue to address. The proposed video watermarking method in this article is specially designed for resisting recompression attacks when quantization parameter (QP) is greatly increased. In the proposed method, by using the texture information and motion information of video, the invariance of video content under different quantization parameters could be found to help improve the anti-recompression attack ability of video watermark. Moreover, the proposed framework does not use a location map which has security risk to locate the watermark. It aims at finding the optimal location of watermark embedding adaptively according to the feature of video content itself. The experiment results indicate that the proposed video watermarking method can not only achieve greater robustness against recompression attack but also effectively limit the degradation in video perceptual quality.
