While encryption is probably the most prominent example of a crypto-graphic problem, modern cryptography is much more than that. In this class, we will learn about pseudorandom number generators, digital signatures, zero-knowledge proofs, multi-party computation, to name just a few examples.

Webpresence or absence of watermark. - Shuffling: based on the concept of texture in an image. Embeddable and unembeddable coefficients of the data are separated. All the coefficients are concatenated into a string and shuffled. The shuffled string is divided into segments of equal length and watermark is embedded into these segments. WebA Crypto-watermarking approach reserves more popularity in certain important fields like medical, military, and law enforcement. This paper discusses detailed the importance of crypto-watermarking techniques and strategies used to improve information security.
Webii. Additive Watermarking: The most straightforward method for embedding the watermark in spatial domain is to add pseudo random noise pattern to the intensity of image pixels. The noise signal is usually integers like (-1, 0, 1) or sometimes floating point numbers. To ensure that the watermark can be detected, the noise is generated WebNational Center for Biotechnology Information
