• Abstract summary: Proposed approach does not try to prevent leak in the first place but rather aims to determine source of the leak. Method works by applying on the screen a unique identifying watermark as semi-transparent image. Watermark image is static and stays on the screen all the time thus watermark present on every captured photograph of the screen.

• Abstract: This paper focuses on investigation of confidential documents leaks in the form of screen photographs. Proposed approach does not try to prevent leak in the first place but rather aims to determine source of the leak. Method works by applying on the screen a unique identifying watermark as semi-transparent image that is almost imperceptible for human eyes. Watermark image is static and stays on the screen all the time thus watermark present on every captured photograph of the screen. The key components of the approach are three neural networks. The first network generates an image with embedded message in a way that this image is almost invisible when displayed on the screen. The other two neural networks are used to retrieve embedded message with high accuracy. Developed method was comprehensively tested on different screen and cameras. Test results showed high efficiency of the proposed approach.

• Invisible Watermarks: Attacks and Robustness [0.3495246564946556]
  We introduce novel improvements to watermarking robustness and minimize degradation on image quality during attack. We propose a custom watermark remover network which preserves one of the watermarking modalities while completely removing the other during decoding. Our evaluation suggests that 1) implementing the watermark remover model to preserve one of the watermark modalities when decoding the other modality slightly improves on the baseline performance, and that 2) LBA degrades the image significantly less compared to uniform blurring of the entire image.

  We propose a semi-fragile image watermarking technique that embeds an invisible secret message into real images for media authentication. Our proposed framework is designed to be fragile to facial manipulations or tampering while being robust to benign image-processing operations and watermark removal attacks.

  Visual Screen Content (VSC) is particularly susceptible to theft and leakage through screenshots. We propose ScreenMark, a robust and practical watermarking method designed specifically for arbitrary VSC protection. To validate the effectiveness of ScreenMark, we compiled a dataset comprising 100,000 screenshots from various devices and resolutions.

  We introduce a novel task for the joint generation of text to image and watermark (T2IW) This T2IW scheme ensures minimal damage to image quality when generating a compound image by forcing the semantic feature and the watermark signal to be compatible in pixels. We demonstrate remarkable achievements in image quality, watermark invisibility, and watermark robustness, supported by our proposed set of evaluation metrics.

  Current watermark detection algorithms require the secret key used in the watermark generation process, making them susceptible to security breaches and counterfeiting during public detection. We propose an unforgeable publicly verifiable watermark algorithm named UPV that uses two different neural networks for watermark generation and detection, instead of using the same key at both stages.

  Watermarking the outputs of generative models is a crucial technique for tracing copyright and preventing potential harm from AI-generated content. We introduce a novel technique called Tree-Ring Watermarking that robustly fingerprints diffusion model outputs. Our watermark is semantically hidden in the image space and is far more robust than watermarking alternatives that are currently deployed.

An embedding strength adjustment strategy is designed to improve the visual quality of the watermarked image with little loss of extraction accuracy.

  Previous watermark removal methods require to gain the watermark location from users or train a multi-task network to recover the background indiscriminately. We propose a novel two-stage framework with a stacked attention-guided ResUNets to simulate the process of detection, removal and refinement. We extensively evaluate our algorithm over four different datasets under various settings and the experiments show that our approach outperforms other state-of-the-art methods by a large margin.
