“…Although the proposed solution was not at all secure, it stressed the issue that the would-be secret key of DSSS can not remain a secret in some applications. Recently, new asymmetric watermarking schemes have been proposed as an interesting alternative especially for the copy protection framework [24], [25], [26], [27], [28], [29]. Although invented independently, the authors showed that these methods shared the same detection algorithm (i.e.…”

This article presents an asymmetric watermarking method as an alternative to classical Direct Sequence Spread Spectrum and Watermarking Costa Schemes techniques. This new method provides a higher security level against malicious attacks threatening watermarking techniques used for a copy protection purpose. This application, which is quite different from the classical copyright enforcement issue, is extremely challenging as no public algorithm is so far known to be secure enough and some proposed proprietary techniques have been already hacked. Our method is thus a try towards the proof that the Kerckhoffs principle can be stated in the copy protection framework.

“…In such schemes, knowledge of the public detection key must not enable an adversary to remove the embedded watermark. There have been some proposals for asymmetric watermarking schemes based on different approaches such as properties of Legendre sequences [62], "one-way signal processing" techniques [37], or Eigenvectors of linear transformations [31]. Unfortunately, none of these schemes is sufficiently robust against malicious parties [30].…”

Abstract. Multimedia applications deploy various cryptographic and watermarking techniques to maintain security. In this context, we survey the main work on two promising approaches for the secure embedding and detection of a watermark in an untrusted environment, and we point out some associated challenges.In the former case we consider Zero-Knowledge Watermark Detection (ZKWMD) that allows a legitimate party to prove to a potentially untrusted verifying party that a watermark is detectable in certain content, without jeopardizing the security of the watermark. ZKWMD protocols are useful primitives for direct proofs of authorship (i.e., without online involvement of a trusted third party) and dispute resolving in distributed systems. In the latter case we consider a Chameleon-like stream cipher that achieves simultaneous decryption and fingerprinting of data, and can serve as the second line of defense for tracing illegal distribution of broadcast messages, termed as Fingercasting. MotivationCopyright protection is a significant prerequisite for intellectual achievements and the creation of original works. In addition to the legal framework that has protected authors since the early ages of book printing, technical measures have become paramount in the age of information technology.Today, various technologies are combined to maintain multimedia security. Core technologies in this context are digital watermarking and cryptography. Many proposals for protecting digital works against misuse and illegal distribution apply robust watermarking methods as basic building blocks. Robust watermarking methods embed additional information, called watermark, into digital content in such a way that this information can be detected, even after the content has been manipulated. Ideally, the robustness property of the watermarking method should guarantee that the watermark cannot be removed without destroying the digital content. Moreover, cryptographic methods, primitives, and protocols are deployed for conditional access allowing the protection of digital content and the restriction of access to legitimate users.

“…There are several ways to deal with the first two security concerns without using a TTP. One way is to employ asymmetric watermarking schemes such as [22,15,13], in which the key to embed a watermark into a work is different from the key required during detection. Unfortunately, known methods are not satisfactory and there are a number of successful attacks [12].…”

Zero-knowledge watermark detection resistant to ambiguity attacks

A zero-knowledge watermark detector allows an owner to prove to a verifier that an image in question indeed contains the owner's watermark without revealing much information about the actual watermark. In such a scenario, the owner publishes a committed watermark before watermark detection so as to show that she knows the watermark before the detection. However, this does not imply that the owner can prove that she knows the watermark before the work appeared in the public. One well known counter example is the invertibility/ambiguity attacks where an adversary can create an ambiguous situation by deriving a forged watermark from a published work, and commits the forged watermark. Furthermore, the adversary may derive a watermark from existing non-watermarked images in the public domain and later claim ownership of them. One solution is to enforce certain constraints on the valid watermarks. In this paper we propose a zero-knowledge watermark detector that prevents the owner from cheating by ambiguity attacks. In addition, it allows the owner to publish a large number of works with different watermarks, while committing only one secret.
