Stenography is an art of embedding hidden data or secret messages over a public channel so third party cannot detect the presence of secret messages. In this stenography method of embedding textual information in an audio file, a proposed technique is first audio sampled and then appropriate bit of each alternate sample is altered to embed the textual information. Here the maximum number of bits that can be used for 6LSB audio stenography without causing noticeable distortion. And using encryption and decryption techniques performing cryptography. So for this used RSA algorithm.
