Steganography is a technique by which any message can be hiding and cannot be seen by necked eyes. It is a very good way by which a message can be prevent from being seen or discovered. Cryptography is distinguished from Steganography in which messages are not completely masked but remain ambiguous by rushing it. By following cryptography technique the hidden messaging cannot be completely prevented from discovered by any third element. Security has a lot of importance and application in

... fields. It is a measure of human carelessness in order to gain the latest technology. Still can be compressed, steganographic embedded and digital watermarked for any transformations. In this paper we have proposed some advanced techniques for finding and analysis of steganographic encapsulate content. Here we put the both statistical and pattern classification techniques which provide us reasonable distinguished schemes for finding encapsulate content of different levels. Our calculations are depends on a some statistical properties of bit strings and wavelet coefficients of image pixels. These measures may have serious effect on human perception to the use of application. As we know that cryptography and steganography are the two different approaches in security, we have tried to combine them. It should be noted that both requirements can also be satisfied solely through cryptographic means. Symmetric key cryptography makes use of single key for encryption and decryption of data. In the proposed approach to dual security we make use of DES (Data Encryption Standard) Algorithm for first phase of encryption and Audio steganography for the second phase of encryption. It's a unique way to draw attention to symmetric key encryption methods such as DES and Audio steganography with LSB implementation.
