Frequency of attacks and intrusions are rising at an alarming rate, thus importance of having a secure mechanism for communication is paramount. Encryption is a robust method for security but its employment attracts eavesdropper’s attention. Steganography comes to rescue by hiding the existence of communication by concealing the secret message in a cover media like text, image, audio or video. ...

One of the issues that arise in the text steganography is the capacity of hiding secret bit. Focusing in Arabic text steganography we propose a sharp-edges method to encounter the issue. This new method will hide the secret bits in the sharp-edges for each character in the Arabic text document. The main processes involved are identifying sharp-edges in the cover-text, secret message preparation...

In this paper we survey different steganography techniques for encrypting the data along with characteristics, difference with cryptography. Steganography is the art and science of hiding information by embedding messages within other, seemingly harmless messages. Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or e...

Digital Steganography is used to protect digital content or data such as text, images, audio and videos that have been tampered maliciously. In this paper we maintain the quality of audio and image and to ensure the ownership, we propose a new LSB (least significant bit) using edge detection in digital steganography. We apply a 2-level steganography on images and audio which make the data which...

Steganography is an ancient art. With the advent of computers, we have vast accessible bodies of data in which to hide information, and increasingly sophisticated techniques with which to analyze and recover that information. While much of the recent research in steganography has been centered on hiding data in images, many of the solutions that work for images are more complicated when applied...

Steganography has been practiced since ancient times. Many Linguistic Steganography (popularly known as Text based Steganography) algorithms have been proposed like Word Spacing, Substitution, Adjectives, Text Rotation, Mixed Case Font etc.. Information Hiding effectively means that the method/technique should be Robust, Secure and have good Embedding capacity. Measure of Similarity between cov...

Steganography is an art of hiding the information without any change in the external appearance of the cover object. Cryptography is a technique to make the information unreadable for unauthorized users. Making the data unreadable and hiding it, will make the data highly secure. Image steganography allows the user to hide a large amount of data inside an image. On transmission side Steganograph...

Steganography is the art of hiding information that evolves as a new secret communication technology. For a long period time, information hiding was done using plain text, still images, video and IP datagram. Embedding secret messages using audio signal in digital format is now the area of focus. There exists numerous steganography techniques for hiding information in audio medium. In this work...

Steganography is an important issue in the field of information safety. This paper concretely designs and carries out an encoding content of the text secret information. The introduction of chaos theory conveniences to the test of steganography characteristics and enhance the safe of steganography. Adopting an improvement type BPCS steganography, this scheme can resist the analysis of the stega...
