Steganography and cryptography are usually used to ensure information
safety in today’s data communication. This paper makes use of audio
steganography technique and encrypted secret sharing to increases the security level of hidden data. The proposed schema can hide digital data in audio file; the resulted stego audio file is separated then into 2- shares encrypted random secure images, which can be transmitted or distributed separately over an threaten communication channel. Using multilevel of security techniques increases the security level of hidden data, and makes it more robust to attack since secret data
is not hidden in one cover media but it is separated across two images, that they will be encrypted and appear completely random.
