Multimedia Cryptology

Abstract

Classical ciphers are typically applied to English text, but they can also be used to encrypt images and sound files to add an audio-visual component to cryptology courses that is appealing to both mathematical and general audiences. Using audio-visual plaintext has the added benefit of more clearly revealing the strengths and weaknesses of classical ciphers since images and sounds are much more error-tolerant than text. Finally, we introduce ECrypt, a free program that makes it easy for everyone to encrypt image and sound files.

Appositeness and usage of Visual Cryptography: An Exploration

“…In [15], [17], [18], [20], the creators have utilized another measurement to depict properties of visual cryptography in fields of interactive media and baseball. Cryptography can scramble sound records more effortlessly than content as sound documents are more mistake tolerant.…”
