A Novel Technique for Secure, Lossless Steganography with Unlimited Payload

Abstract

Abstract-Steganography is a way of sending hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message. There exist many methods for digital image steganography. But most of the existing techniques are based on lossy approach. And the major challenges of steganography are security of hidden communication and the size of message that can be embedded in an image. So, this paper is intended to propose an image steganography technique based on matches between cover image and secret data. This proposed method maintains the cover image as such and has unlimited capacity of payload.Index Terms-Lossless steganography, secure steganography, search partition size, unlimited payload.

“…Someone can consider that the Cryptography and Steganography are cousins belongs to spy craft family. Cryptographic convert the secret data into the unintelligible (unreadable) form, while the Steganography attempt to conceal the presence of secret data by hiding it in the cover file [5].…”
