A Novel Approach to Audio Steganography on Audio Input for Secure Communication

In today’s digital age, one is focused on copyright-dependent people and organizations, especially in the entertainment business, and concerned with the privacy of data. The differences in the human voice makes it challenging to produce the watermark needed to protect audio signals from unauthorized access. Enhancing the security of the transmitted data is the main goal of the steganography method. The steganographic file cannot be accessed or used improperly by the unauthorized user. To maintain data confidentiality and privacy, audio steganography is equally applicable to non-technical sectors. Steganography, is often known as security by obscurity. Steganography functions by substituting bits of different, unseen data for pieces of redundant or unnecessary data in common computer files (such as images, sound, and text). This secret data may be in the form of plain text, cipher text, or even sound. In a computer-based audio Steganography system, digital sound is used to covertly encode messages. By slightly modifying the byte sequence of a sound file, the hidden message is implanted. This paper proposes a robust steganography technique that uses the LSB method for performing steganography and AES for providing added security.
