Many digital image watermarking schemes have been developed to embed copyright
information into an image. However, an attacker may reuse parts of a watermarked image by …

In this chapter, we first overview the applications of combinatorics in cryptography. Then, we
take look at some historical applications of non-combinatorial squares and cubes in …

Perfectly-secure cryptography is a branch of information-theoretic cryptography. A perfectly-
secure cryptosystem guarantees that the malicious third party cannot guess anything …

Sudoku matrix is a unique Latin square-based mathematical structure, which may have
several dimensions like 2D, 3D, etc. This structure has several applications in different …

Sudoku is a complicated multidimensional mathematical structure with several applications
in various computer science domains. 3D Sudoku, compared to 2D, has one more …

Copyright information embedded in a digital data may disappear or become undetectable
due to additive noise accidentally or deliberately introduced to a watermarked image …
