WebExisting constructions of software watermarking from standard cryptographic assumptions all focus on watermarking symmetric-key primitives, notably, PRFs [KW17,QWZ18,KW19]. The one exception is the work of Baldimtsi et al. [BKS17], who showed how to watermark public-key cryptographic primitives, but in a stateful setting, and under WebDec 30, 2024 · Cryptographic Watermark A watermark is a semi-transparent mark (a logo or text) that is embedded onto an image. The watermark signals who is the original author of the work. It’s largely seen in photographs and increasingly in videos.
Using cryptographic and. watermarking algorithms IEEE …
Webwatermark in this case is called blind watermark extraction. The inability to access the original signal limits the amount of data that can be embedded in a given host signal. It also renders data extraction more difficult. In this paper, a cryptographic watermark embedding tech-nique based on discrete logarithm is proposed. The proposed 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 … mick jagger filefactory

Web(PKC 2024) showed how to watermark cryptographic functions such as PRFs using indistinguishability obfuscation. Notably, in their constructions, the watermark remains … WebOct 20, 2024 · Watermarking cryptographic functions has various real-life applications. Consider for instance the case of VPN clients. An organization might wish to distribute VPN clients to its employees where every employee has a public/secret-key pair. Watermarking the VPN client restricts the employees from sharing their clients since, due to the ... Digital watermarking for relational databases has emerged as a candidate solution to provide copyright protection, tamper detection, traitor tracing, and maintaining integrity of relational data. Many watermarking techniques have been proposed in the literature to address these purposes. A survey of the current … 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 extraction of a steganographic spread … See more A digital watermark is called robust with respect to transformations if the embedded information may be detected reliably from the … See more The evaluation of digital watermarking schemes may provide detailed information for a watermark designer or for end-users, therefore, different evaluation strategies exist. Often used by … See more Digital watermarking may be used for a wide range of applications, such as: • Copyright protection • Source tracking (different recipients … 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 Epson and Kodak have produced cameras with security features such as the Epson PhotoPC 3000Z and the Kodak DC-290.
