Cryptographic watermarking
WebJul 14, 2024 · Digital watermarking embeds unremovable information called a “mark” into digital objects such as images, video, audio files, and program data without changing their functionalities. This article provides a brief overview of recent advances in watermarking for cryptographic programs and insights behind them. Keywords. Program watermarking ... 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 cryptographic watermark is said to be … 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.
