Securing Informative Text using Color Visual Cryptography

Abstract

The rising threats to information security are increasing at an alarming rate. The most powerful and universal approach to counter such threats is encryption. Conventional encryption techniques use substitution and transposition. Substitution technique change plaintext into cipher text. In all conventional substitution techniques characters, numbers and special symbols are replaced with other characters, numbers and special symbols. In this project, an innovative substitution method is proposed to generate a better cipher than the existing substitution algorithms. This method re-emphasizes on the substitution of characters, numbers and special symbols/characters with color blocks. This project is based on Play Color Cipher. The crypt-analysis is done on this will prove that the cipher is strong.
