Protocols for Watermark Verification

deter piracy of multimedia content, the owner typically reveals the watermark in the process of establishing piracy. Once revealed, a watermark can be removed. We eliminate this limitation by using cryptographic protocols to demonstrate the presence of a watermark without revealing it. C onsider an application where multi-media content is electronically distributed over a network. To discourage...

Zero Knowledge Watermark Verification Protocols

Watermark technology has been developed to tackle the problem of unauthorized copying and distribution of digital data. Several different schemes have been proposed in the last few years, but most of them are symmetric, i.e., the key used for watermark embedding is just the same used for watermark detection. However, in many applications, an asymmetric scheme is needed, where the secrete inform...

Protocols for Watermark Veriication

Digital watermarks have recently been proposed for the purpose of copy deterrence of multimedia content. Copy deterrence using digital watermarks is achieved by inserting a unique watermark into each copy of the image sold which could be used to trace unauthorized copies to the erring buyer. However, all the schemes proposed in the literature suuer from the following major limitation which is g...

automatic verification of authentication protocols using genetic programming

implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
