Steganography is the art and science of concealing communication. The goal of steganography is to hide the very existence of information exchange by embedding messages into unsuspicious digital media covers. Cryptography, or secret writing, is the study of the methods of encryption, decryption and their use in communications protocols. Steganography manipulates data to ensure the security of in...

The growth of the Internet has stimulated the use and the misuse of Steganography. At its simplest level, Steganography, the art of hiding secret messages within the structure of another media. While legitimate and justifiable applications for steganography exist, criminally-minded people or organisations can also use it for underground, illicit and deliberately secret communication. The object...

A secure method for steganography is proposed. Pixelvalue differencing (PVD) steganography and bit-plane complexity segmentation (BPCS) steganography have the weakness of generating blocky effects and noise in smooth areas and being detectable with steganalysis. To overcome these weaknesses, a secure bit-plane based steganography method on the spatial domain is presented, which uses a robust me...

Design and Implementation of Steganography along with secured message services in Mobile Phones is used to provide security to the data that flows across the mobiles. Two people may communicate securely by encrypting the message sent between them. Now a day, several methods are used for communicating secret messages for defense purpose or in order to ensure the privacy of communication between ...

-Steganography is a term used for covered writing. Steganography can be applied on different file formats, such as audio, video, text, image etc. In image steganography, data in the form of image is hidden under some image by using transformations such as ztransformation, integer wavelet transformation, DWT etc and then sent to the destination. At the destination, the data is extracted from the...

in this paper, a faster method for embedding cryptographic information in the image ispresented by expressing the concept of latent prints (steganography). data is encrypted bytwo methods before embedding to increase reliability. then they are embedded into the imageby a button, a method has been expressed to reduce potential noise impact on the wayinformation is encoded.

Steganography is one of the methods of secret communication that hides the existence of hidden message. It can be defined as the study of invisible communication that usually deals with the ways of hiding the existence of the communicated message. The hidden message may be text, image, audio, video, etc. The files can be a cover image after inserting the message into the cover image using a ste...

We analyze the complexity of the steganography problem and show that the decision version of the problem is NP-complete through transformation from the Knapsack problem. We also give a pseudo-polynomial time algorithm to optimally solve the steganography problem. This optimal algorithm can also be applied to image steganography.

The current methods of communication using steganography techniques involve the use of carrier files including network protocols. The current study presents a new method of communication using steganography techniques available today, the carrier being a ping. The study will also present the most effective ways of prevention against this form of secret communication. Key-Words: steganography, i...

Steganography is the art and science of concealing information in such a way that only the sender and intended recipient of a message should be aware of its presence. Digital steganography has been used in the past on a variety of media including executable files, audio, text, games and, notably, images. Additionally, there is increasing research interest towards the use of video as a media for...
