“…In this case, a technology that can trace leakage of the screen displayed content after it was captured by a camera has been investigated. Screen-cam robust watermarking [8] is a highly robust digital watermarking technology, which not only can resist common image processing attacks, but also has a good performance to resist screen-cam attacks. Therefore, how to design a screen-cam robust watermarking algorithm for tile satellite images is a meaningful issue.…”

“…Multi-domain-based methods modulate the coefficients of the wavelet domain to embed watermark message combined with another domain-based method to achieve synchronization [21]- [23]. However, global watermarks are restricted to the desynchronization caused by stitching and cropping attack [8], [24].…”

“…In summary, the ideas of the watermarking algorithms designed for print-scan and print-cam attacks can be applied to screen-cam process due to the similarities of cross-media signal transmission. But the experiments in [8] show that the state-of-art methods of these algorithms are not applicable in screen-cam process due to the differences between screen-cam and print-scan/cam processes, for example, the quality degradation caused by moiré noise and illumination distortion.…”

“…Commonly, one frame of the video only carries a few bits. To embed multibits message and extract watermark message from one single screen-captured image, Fang et al [8] and Chen et al [28] proposed two different feature and frequency domain-based watermarking schemes, and Wang [29] improved the patternbased method of [11] by image morphology methods to make it robust to screen-cam process. At the extraction side, these three methods all need to correct perspective distortion by manually selecting four points with additional information.…”

“…At the extraction side, these three methods all need to correct perspective distortion by manually selecting four points with additional information. Methods by [8] and [29] need to record the four corners of the original image in advance, which means the original size has to be known. Method by [28] at least needs to know the aspect ratio of the image or aspect ratio of the screen to help estimate the coordinates of selected four points.…”

To achieve watermark synchronization from an image with perspective distortion is a challenge. This paper proposes a screen-cam robust and blind watermarking scheme for tile satellite images, which means we do not need any user interaction or additional information in watermark detection. To achieve this, at the watermark embedding side, we divide tiles into synchronization tiles and message tiles, and propose a discrete Fourier transform (DFT) based embedding method to cope with the quality degradation caused by screen-cam process. At the extraction side, based on the idea of template matching, we first use a synchronization response index to estimate an appropriate scale level and positions of embedded synchronization watermarks from the noise component, which is estimated by Wiener filter. Then, we propose verification, selection, and precise locations methods to ensure the effectiveness and accuracy of synchronization detection results. After that, we can extract the regions of message tiles. Finally, we extract watermark message based on the local max value from the DFT domain of the noise component. Experimental results demonstrate the validity of the proposed scheme against common attacks and screen-cam attack with a tripod as well as handhold shooting.

Metaverse's augmented reality (AR) function allows virtual information to be seamlessly superimposed onto real scenes through the camera of a head‐mounted device. However, this raises concerns about privacy protection and copyright authentication when transmitting cross‐media information. Additionally, there is a risk of secret information leakage due to screen candid shooting in the real world. Ensuring information security and copyright authentication in case of unauthorized screen capturing is crucial. To prevent information loss and interference from cross‐media transfer between screens and cameras, we implement digital watermarking for copyright protection. We have proposed an innovative framework for automatic document watermarking that can resist screen‐shooting. Our approach involves embedding a ring watermark in the document underlay. On the extraction side, the watermark extraction process is divided into three key steps: automatic location, automatic correction, and automatic extraction. First, the document image is located in the covert photography. Then, perspective correction is performed based on the text line features of the document. Finally, the watermark information is extracted by combining the ring watermark features. Our method is capable of automatically extracting watermarks from covert photography while considering aspects such as concealment, robustness, and visual quality. The watermark is embedded in the document underlay, which ensures good visual quality and does not affect the normal reading and editing. We also propose various embedding strength schemes that can adapt to different usage scenarios, providing resistance to screen‐shooting or screenshot attacks, as well as various noise attacks. Through extensive experiments, we have demonstrated the feasibility of the proposed automated framework and the robustness of the watermarking algorithm, as well as the superiority and broad application prospects of our method.

Digital data communication or sharing has increased day by data because of excessive usage of the Internet. It is necessary to protect digital data from unauthorized access. However, it is very difficult to ensure the authenticity of the host data. Digital image watermarking is a significant technology for ensuring this authentication. Existing hybrid domain algorithms are not effective enough to overcome the potential challenges of watermarking techniques. Hence, the current image watermarking technology is devoted toward developing more effective methods with optimization and machine-learning algorithms for ensuring a better trade-off among the basic design requirements like imperceptibility, robustness, and capacity simultaneously in addition to security that can be confirmed with lightweight image encryption algorithms. In this research, a framework of standard image watermarking system for ensuring the basic design requirements is given, the existing literature is studied, and the recent trends of image watermarking techniques and their applications are also described to investigate the performance of the state-of-the-art methods along with their limitations. Finally, we have concluded our study by pointing to new research directions.
