Cryptographic watermarking
WebJun 1, 2024 · Security like confidentiality, privacy, and integrity of medical data is still a challenge. It is observed that the existing security techniques like digital watermarking, encryption are not efficient for real-time use. This paper investigates the problem and provides the solution of security considering major aspects, using Visual Cryptography ... WebDigital images are transferred with ease through the network. Many users are using the images without the knowledge of the owners. Therefore, a novel watermarking scheme is proposed to ensure copyright protection and authentication of images using cryptography techniques. Here, a quick response (QR) image is generated for a watermark image that …

WebNov 8, 2006 · A joint watermarking and ciphering scheme for digital images is presented that allows to cipher a watermarked image without interfering with the embedded signal … WebLattice-Based Cryptography. Lattice-based cryptography is one of the leading candidates for post-quantum cryptography. A major focus of my work has been on constructing new cryptographic primitives such as zero-knowledge proof systems, watermarking, and more, from standard lattice assumptions.
WebDec 31, 2024 · cryptographic watermark. A watermark is a semi-transparent mark (logo or text) embedded in an image. A watermark indicates who is the original author of the work. Mostly seen in photos and increasingly in video. ChatGPT watermark text contains a form of encryption that embeds a pattern of words, letters, and punctuation in the form of a secret … Webwatermarking, in this paper we propose novel watermarking schemes based on the discrete logarithm problem (DLP) and the Fermat’s little theorem for general purpose digital rights …
A digital watermarking method is referred to as spread-spectrum if the marked signal is obtained by an additive modification. Spread-spectrum watermarks are known to be modestly robust, but also to have a low information capacity due to host interference . See more A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is … See more The term "Digital Watermark" was coined by Andrew Tirkel and Charles Osborne in December 1992. The first successful embedding and … See more The information to be embedded in a signal is called a digital watermark, although in some contexts the phrase digital watermark means the difference between the … See more The evaluation of digital watermarking schemes may provide detailed information for a watermark designer or for end-users, therefore, different … See more Epson and Kodak have produced cameras with security features such as the Epson PhotoPC 3000Z and the Kodak DC-290. Both cameras added … See more Digital watermarking may be used for a wide range of applications, such as: • Copyright protection • Source tracking (different recipients get differently watermarked content) • Broadcast monitoring (television news often contains watermarked video … See more A digital watermark is called robust with respect to transformations if the embedded information may be detected reliably from the marked signal, even if degraded by any number of transformations. Typical image degradations are … See more WebWatermarking cryptographic functions have various real-life applications. Consider for instance, the case of the VPN clients. An organization might wish to distribute VPN clients to its employees where each employee is …
WebHowever, we see some of the solutions are better than others. For example, the solution with 01, and 11 as watermark, they both have five letters as the solution, and, however, the other two have nine literals. This is one of the challenges for watermarking, which is known as fairness, and we will talk about this later. Let's see another example.
