A Novel Audio Steganographic Algorithm LSB Based Subtraction Operation Used in Sattolo's and Crypto-Algorithm

Abstract

With the widespread use of digital communication operated by the need for ever-increasing interconnectedness and global events, the necessity for greater privacy and security during online information sharing is evident, as more enemies emerge to infringe on a fundamental human right. Cryptography and steganography have both failed to sufficiently safeguard data in transit. Audio steganography solutions have largely suffered from imperceptibility concerns, which manifest as glitches that may be heard, generating suspicion in the minds of those who are interested. This study proposes combining the two to produce a better solution that combines a unique Subtraction operation scheme with AES cryptography and LSB .wav audio steganography, which overcomes the flaws of the separate protocols and strengthens their merits. One such advantage of the suggested approach is its deep spatial analysis and high PSNR and MSE values. The finished product is capable of deception utilizing audio files, preserving secrets, and assuring private conversation. Keywords: Subtraction, AES, Audio Steganography, Sattolo's, LSB
