Adaptive Steganographic Algorithm using Cryptographic Encryption RSA Algorithms
Manoj Kumar Sharma, Jaipur National University Dr. Amit Upadhyaya, Jaipur National University Shalini Agarwal, Pursuing M.Tech, Banasthali University, Banasthali

ABSTRACT
Cryptography is the art of securing information by applying encryption and decryption on transmission data which ensure that the secret can be understood only by the right person.[1] Steganography is the process of sharing information in an undetectable way by making sure that nobody else can even detect the presence of a secret. If these two methods could be combined, it would provide a fool-proof security to information being communicated over a network. This paper propose two different steganographic algorithms using RSA cryptographic algorithms and with some random functions. The message is transformed into a cipher audio signal using a key, concealed into another cover data using Steganography by converting it into an intermediate encrypted and message using random number generator and with the help of RSA algorithms. The proposed method thus achieves a high degree of security for information. Keywords— Metamorphic cryptography, Cryptography, Steganography, Matrix Multiplication, Angular Encryption, Dynamic Encryption, Color Key, Cipher Image, Intermediate Text, Color Key Matrix, Data Matrix, Paradox.

INTRODUCTION
Information security is of utmost importance in today’s fast developing era. Information or messages are being exchanged over various types of networks. With the huge growth of computer networks and advancement in technology, a huge amount of information is being exchanged. A large part of this information is confidential or private which increases the demand for stronger encryption techniques. Security

matching upper and lower bounds on the maximum rate of any secure stegosystem. We introduce the concept of steganographic key exchange and public-key steganography, and show that provably secure protocols for these objectives exist under a variety of standard number-theoretic assumptions. We consider several notions of active attacks against steganography, show how to achieve each under standard assumptions, and consider the relationships between these notions. Finally, we extend the concept of steganograpy…

INTRODUCION Steganography is the art of concealing private or sensitive information within a carrier that for all intents and purposes, appears innocuous. It comes from the Greek words steganós (covered) and graptos (writing). Simply put, if you were to view the presented information, it would appear to be something that does not warrant further analysis due to the fact that it does not LOOK or SOUND like anything that contains sensitive information. Steganography has been used for hundreds of years…

Abstract This paper introduces steganography, the art and science of hidden writing. The purpose of steganography is to hide the existence of a secret message from a third party. The most popular modern application of steganography involves concealing messages within least significant bits of image or sound files. Another application of modern steganography is a steganographic file system. Steganography is also used by some modern printers, where tiny yellow dots that contain encoded printer…
