Analisis kinerja Algoritma LSB Novel dalam peningkatan jumlah Layer Bit yang bisa disisipkan pesan pada Steganografi Audio

Abstract

Secret information exchange is important today. It can be implemented by embedding a message into another file. Audio file is one media that can be used to embed a secret message. LSB Steganography method is an embed technique that is easy to implement with less complex computation, but the amount of bit layers that can be embedded is still low. Implementation of Novel algorithm with error diffusion tries to reduce the weakness. The result of embedding process by Novel algorithm with error diffusion shows higher amount of bit layers which can be embedded than standard LSB algoritm with asuming a good quality of audio has PSNR value more than 30 dB and it is robust to known cover object attack, so Novel algorithm with error diffusion is better than standard LSB algorithm . The time needed to embed message by Novel algorithm with error diffusion has linear graphic.
