Camera Based Watermark Extraction – Problems and Examples
نویسندگان
چکیده
Cameras are more and more common in mobile phones and this creates new opportunities and threats to digital watermarking. We discuss about the difficulties that occur while reading a watermark with a digital camera or a camera phone and what kind of applications and technical solutions have already been invented. Not much research has been done on this field but commercial applications have already showed the potential demand for print-cam robust watermarking methods.

Two Novel Chaos-Based Algorithms for Image and Video Watermarking
In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...
متن کاملA Public Key Watermark for Image Verification and Authentication
We propose in this paper a public key watermarking algorithm for image integrity veri cation. This watermark is capable of detecting any change made to an image, including changes in pixel values and image size. This watermark is important for several imaging applications, including trusted camera, legal usage of images, medical archiving of images, news reporting, commercial image transaction,...
متن کاملAssessment of camera phone distortion and implications for watermarking
In this paper, the distortion introduced by cameras of smart phones such as iPhone 3G and iPhone 3GS is measured and quantified. In particular, the spatial frequency response (SFR) of a mobile camera phone is measured [1]. A new robustness metric that relates camera phone quality to watermark robustness is defined. Experiments were conducted using watermarked images to verify the predictions ma...
متن کاملDigital Watermark Detection in Visual Multimedia Content
Digital watermarking has been proposed as a technology to ensure copyright protection by embedding an imperceptible, yet detectable signal in visual multimedia content such as images or video. Watermark detection is an integral component of a watermarking system. This cumulative thesis addresses watermark detection problems in important application domains such as scalable multimedia, raw/demos...
متن کاملProposing an effective approach for Network security and multimedia documents classically using encryption and watermarking
Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
