Steganography hides the very existence of a message so that if successful it generally attracts no suspicion at all. There are many techniques to perform Steganography on electronic media, most notably audio and image files. In this paper, we present a new steganographic technique for embedding messages in BMP image. The main goal of this method, like any Steganography techniques must do, is to...

Cryptography and Steganography are two techniques commonly used to secure and safely transmit digital data. Nevertheless, they do differ in important ways. In fact, cryptography scrambles data so that they become unreadable by eavesdroppers; while, steganography hides the very existence of data so that they can be transferred unnoticed. Basically, steganography is a technique for hiding data su...

This paper shows the possibility of exploiting the features of Ecipher method by using both cryptography and Information hiding in Audio signal methods used to send and receive the message in more secured way. Proposed methodology shows that successfully using these Poly substitutions methods (Proposed E-Cipher) for Encode and decodes messages to evolve a new method for Encrypting and decryptin...

Steganography is the art and science where writing messages are hidden in such a way that no user at end side knows exactly what message delivered. Data hiding characteristic related to object-oriented programming objects associated with data having predefined template. Thus, all not required by an object can be said "hidden". The word "Steganography" of Greek origin means "covered, or writing"...

Steganography is the art and science of hiding secret messages in public communication so that presence cannot be detected. There are two distribution-preserving steganographic frameworks, one sampler-based other compression-based. The former requires a perfect sampler which yields data following same distribution, latter needs explicit distribution generative objects. However, these conditions...

Existing steganography methods are still lacking in terms of capacity. Hence, a new steganography method for Arabic text is proposed. The method hides secret information bits within Arabic letters using two features, which are the moon and sun letters and the redundant Arabic extension character “-” known as Kashida. The Arabic alphabet contains 28 letters, which are classified into 14 sun lett...

Steganography is a type of secrete communication that hides the secrete information. It deals with the different ways of hiding/embedding the secrete information such as text, image, audio or video files inside another multimedia files with the help of private key. The hidden information is termed as secrete file and the file in which the secrete file is hidden is termed as cover file. The file...

Steganography is the science of communicating in the hidden manner. This paper presents a robust and secured Image Steganography method capable of embedding high volume of text information in digital cover-image without incurring any perceptual distortion. The method is based on compression and encryption. In order to achieve high capacity, dictionary based lossless compression techniques are u...

In this paper, an effective method was introduced to steganography of text document in the host image. In the available steganography methods, the message has a random form. Therefore, the embedding capacity is generally low. In the proposed method, the main underlying idea was the sparse property of scanned documents. The scanned documents were converted from gray-level form to binary values b...
