Steganography is the hiding of payload data within cover data. The goal of a steganographic method is to minimize the visually apparent and statistical differences between the cover data and a steganogram while maximizing the size of the payload. Current digital image steganography presents the challenge of hiding data in a digital image in a way that is robust to image manipulation and attack....

Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. It comes under the assumption that if the feature is visible, the point of attack is evident, thus the goal here is always to conceal the very existence of the embedded data. Steganography has various useful applications. However, like any other science...

Today’s all the multimedia work done via internet so it’s an urgent need to protect the data from malicious attacks. This lead to the research in the area of Digital watermarking and cryptography which intends to protect the copyright information of the intellectuals. In this paper a DCT based steganography scheme is proposed which provides higher resistance to image processing attacks such as ...

DNA cryptography is a new field which has emerged with progress in the research of DNA computing. As a special cryptography, DNA steganography is safer than ordinal cryptography, only if the primer sequences are concealed from an adversary however this is not easy . DNA cryptography and steganography differs from the conventional cryptology in the terms that the keys and the cipher texts are al...

Encrypted messages sending frequently draws the attention of third parties, perhaps causing attempts to break and reveal the original messages. Steganography is introduced to hide the existence of the communication by concealing a secret message in an appropriate carrier like text, image, audio or video. Quantum steganography where the sender (Alice) embeds her steganographic information into t...

With the widespread penetration of the internet, communication between distant parties has become effortless and now occurs on a much larger scale. Given the open access of the internet, the secure communication of sensitive information is a prevailing concern for the medium’s users. As a result, steganography, the art of hiding information within a communiqué, has entered the digital age. Digi...

Steganography, coming from the Greek words stegos, meaning roof or covered and graphia which means writing, is the art and science of hiding the fact that communication is taking place. Using steganography, you can embed a secret message inside a piece of unsuspicious information and send it without anyone knowing of the existence of the secret message. Steganography and cryptography are closel...

Retention of secrecy is one of the significant features during communication activity. Steganography is one of the popular methods to achieve secret communication between sender and receiver by hiding message in any form of cover media such as an audio, video, text, images etc. Least significant bit encoding is the simplest encoding method used by many steganography programs to hide secret mess...

(Markus Kahn, 1995) defines Steganography as art and science of communicating in a way which hides the existence of the communication. In contrast to cryptography, where the enemy is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of steganography is to hide messages inside other innocent messages in...

Steganography is the field of hiding messages in apparently innocuous media (e.g. images), and steganalysis is the field of detecting these covert messages. Almost all steganalysis consists of hand-crafted tests or human visual inspection to detect whether a file contains a message hidden by a specific steganography algorithm. These approaches are very fragile – trivial changes in a steganograp...
