This paper is all about the study of the steganography and techniques used for the steganography. Firstly we will understand the term steganography, use of steganography and techniques used for the steganography. In steganography, we use text transformation, LSB (Least Significant Bit), graphics or image steganography, audio steganography, steganography in videos and animations etc. This paper ...

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...

Steganography can be defined as a method of hiding data within a cover media so that other individuals fail to realize their existence. Image, audio and video are some popular media for steganography. But text is ideal for steganography due to its ubiquity and smaller size compared to these media. However, text communication channels do not necessarily provide sufficient redundancy for covert c...

Steganography is an important area of research in recent years involving a number of applications. It is the science of embedding information into the cover image viz., text, video, and image (payload) without causing statistically significant modification to the cover image. This paper deals with hiding text in an image file using using various Steganography techniques. Discrete Cosine Transfo...

Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...

Establishing hidden communication and conveying information secretly has been of interest since long past ago. One of the methods introduced for establishing hidden communication is Steganography. Methods of Steganography have been mostly applied on images, audios, videos, and text files while the major characteristics of these methods are to change in the structure and features so as not be id...

Today, internet is widely used to transfer various secret data in all over the world. During transmission secret data, unauthorized viewers can monitor it. Steganography is mainly used to protect secret data from unauthorized viewers over communication channel. Steganography means the covered or hidden writing. There exits many steganography model such as image, audio, video or text. Among them...

Cryptography is the science and art of encrypting and decrypting text data where Steganography is the science and art of hiding information. Steganography deals with composing hidden message so that only the sender and receiver know that the message even exists. A novel approach i. e. CryptSteg is introduced where sender embedding text message in the picture and send it to the receiver. In this...

This paper presents a survey of text steganography methods used for hiding secret information inside some covertext. Widely known hiding techniques (such as translation based steganography, text generating and syntactic embedding) and detection are considered. It is shown that statistical analysis has an important role in text steganalysis.
