The combination of Steganography and cryptography algorithms can improve the security of data you want to keep secret. Pixel Value Differencing (PVD) algorithm combined with Word Auto Key Encryption (WAKE) algorithm and Modular Multiplication Block Cipher algorithm can produce good ciphertext and inserted on image media by using PVD algorithm that convert each ciphertext into pixel.
