Abstract: The recent growth in computational power and technology has propelled the need for highly secured data communication. One of the best techniques for secure communication is Steganography-a covert writing. It is an art of hiding the very existence of communicated message itself. The process of using steganography in conjunction with cryptography, called as Dual Steganography, develops a sturdy model which adds a lot of challenges in identifying any hidden and encrypted data. Using cryptographic techniques to encrypt data before transmission may forestall any type of security problems. But the camouflaged appearance of encrypted data may arouse suspicion. Therefore using steganography inside steganography, give rise to improved version of dual steganography which will provide better security. This paper presents a technique for hiding data with two level of security to embed data along with good perceptual transparency and high payload capacity. Here the secret data is not restricted to images only but also applicable to any text, audio or video.
