AES Hybridization with LSB Encoded Audio Steganography

Abstract

The biggest challenge in the recent digital communication era is the security of information. Data protection has been given particular priority for professionals and researchers of industry due to the ubiquitous use of internet and the wide range of public and private digital data. Three primary methods are currently being used: cryptography, watermarking and steganography. Steganography is the technique of embedding the secret message into another carrier message. Steganography's primary aim is to secretly transmit data. Secret data is embedded in digital sound in a computer-based audio system Stenography. The integration of secret data into digital sound is generally much more intricate process than the incorporation of data into other host media However, integration of data into audio Stenography is safer thanks to fewer techniques for steganalysis.. This study proposes a method for maintaining the anonymity of Simple Text communicated over the internet that combines AES encryption and LSB Encoded Steganography. In the proposed method, even if the prowler decodes applied steganography technique, he/she will not be able to obtain the original data as it would be in its encrypted form. Once the encrypted data is hidden in the audio stream using steganography, the suggested system provides a high quality of Peak Signal-to-Noise Ratio (PSNR) and Signal-to-Noise Ratio (SNR) with no audible distortion.
