Abstract This paper proposes a cryptographic technique on images based
on the Sudoku solution. Sudoku is a number puzzle, which needs applying
defined protocols and filling the empty boxes with numbers. Given a small size
of numbers as input, solving the sudoku puzzle yields an expanded big size of
numbers, which can be used as a key for the Encryption/Decryption of images.
In this way, the given small size of numbers can be stored as the prime key,
which means the key is compact. A prime key clue in the sudoku puzzle always
leads to only… More >
