Steganography is the science of hiding messages in a manner that only the intended users knows the presence of the secret message. Hiding the information within a computer file also comes under Steganography. In digital steganography these media files are suitable because of their large size. LSB insertion is one of the basic techniques prominently used in steganography. This paper presents an ...

as a society, humans have continually sought new and efficient ways to communicate. The earliest methods included cave drawings, smoke signals, and drums. Advancements of civilization introduced written language, telegraph, radio/television, and most recently electronic mail. As more and more communication is conducted electronically, new needs, issues, and opportunities are born. Steganography...

Steganography is a science dealing with writing hidden messages in a particular way that only the sender & the intended recipient are able to decipher so as to provide security in open environment like internet. Steganography attempts to hide the very existence of the message and make communication undetectable. Important domains, besides classic computing, where steganography can be applied ar...

The proposed scheme is a multi level steganography in which steganography is done at two places. The cover image is divided into fixed size blocks and then Discrete Cosine Transformation is applied into each block of cover image. The resulting DCT coefficients are quantized using quantization process. In the quantized DCT coefficient, the encrypted data file is embedded by using Least Significa...

In this paper we propose a new method for the evaluation of network steganography algorithms based on the new concept of “the moving observer”. We considered three levels of undetectability named: “good”, “bad”, and “ugly”. To illustrate this method we chose Wi-Fi steganography as a solid family of information hiding protocols. We present the state of the art in this area covering well-known hi...

The aim of steganography is to conceal the very existence of hidden communication, so imperceptibility is the primary demand. However there are short of corresponding evaluation methods. Most researchers still use Peak-Signal-to-Noise Ratio (PSNR) for their imperceptibility evaluation, while ignoring the speciality of steganography. In this paper, firstly, we present an objective method of impe...

Steganography is the art and science of secret communication. Various types of media, such as images, videos, audio etc. can be used to hide the message. This paper presents an approach to steganography using LBP on a cluster formed by the CIELAB (Informally called Lab) based k-means clustering. Image Steganography embeds the secret message into the images exclusively. Basically Image Steganogr...

In this paper, Cryptography and Steganography techniques are combined to enhance the security level of data communication over an unsafe distributed network. The standard LSB(Least Significant Bit) steganography method is also modified by digitally signing a information of starting position of hided message in image, so that any other third person can’t determine the position of beginning of hi...

----------------------------------------------------------------------ABSTRACT----------------------------------------------------------In the recent trend steganography plays an important role in providing secrecy in internet. Steganography works by replacing bits of useless or unused data in regular computer files with bits of different, invisible information. Cryptography is used to scramble...

Steganography is the art of hiding secret information in media such as image, audio and video. The purpose of steganography is to conceal the existence of the secret information in any given medium. In the world of E-Commerce internet banking is one of the indispensable applications. Security issues are to be addressed critically in internet banking applications and it directly influences the c...
