Abstract
Simple text exchanged on the internet can be intercepted and confidentiality can be compromised by an intruder. In this paper, a solution is proposed that uses a combination of encryption and steganography to maintain the confidentiality of the simple text exchanged. From the time people have started using the internet, security has become a major concern. Steganography provides security up to some level, there has been a huge amount of research done in relation to steganography. Steganography is considered to be secure only until someone knows that the steganography is applied, the moment attacker knows that the steganography is applied steganography fails. Steganography can be easily broken, and the original text can be obtained. In the proposed system, if the intruder/attacker breaks steganography, he/she will not be able to get the original text as it would be encrypted. The proposed technique provides a high quality of Peak Signal-to-Noise Ratio (PSNR) and Signal to Noise Ratio (SNR) when steganography is applied. There is no major audible distortion after the encrypted text is hidden in the audio file.
