Cryptographic watermarking
Webside effect that yields longer cryptographic signatures and watermarks is produced. Such an obstacle discourages [1] from being a robust watermarking method in resisting geo-metric attacks [6, 10]. On the other hand, it can also be observed that the ex-isting methods that were proposed to deal with the proto- WebAug 1, 2024 · Watermarking is a way to embed special information called a “mark” into digital objects such as images, videos, audio, or software so that the marked object has the same appearance or behavior of the original object. Moreover, it should be difficult for an adversary to remove the mark without damaging the object itself.

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. 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 .
