Today, in this new era of the internet, Information Security is becoming the biggest challenge for the world due to the rapid growth of internet users day by day. Unauthorized access to secret data can have serious repercussions like a financial loss. One of the best techniques for secure communication is Steganography-or covert writing. It is an art of hiding the very existence of communicating the message itself. This research presents a state of dual stenographic technique. Dual Steganography combines two security mechanisms, steganography and cryptography both together. This mechanism has the advantage of providing high security and low time complexity. This research proposes a dual steganography technique with an additional level of security. The proposed algorithm embeds secret text messages in cover image in two phases. The two phases include a chaotic map cipher technique for encrypting text and LSB (Least Significant Bit) image steganography technique for hiding encrypted text in an image. The text containing encrypted data is hidden in an RGB image.
