A Review paper on Steganography TechniquesEditor IJMTER
Â
In todayâs world the art of sending & displaying the hidden information especially in
public places, has received more attention. And so it has to face many challenges. Therefore,
different methods have been developed so far for hiding information in different cover media.
Steganography is the art and science of invisible communication which takes place between two
different entities. This is done by hiding the information in other information. It is the way of hiding
the existence of the communicated information. Steganography is often confused with cryptography
because the two are similar in the way that they both are used to protect confidential information.
Steganography is different from cryptography. Cryptography focuses on keeping the contents of a
message secret, while steganography focuses on keeping the existence of a message secret [4]. This
paper intends to give an overview of security systems with a main concentration on steganography,
its uses and techniques.
A brief over overview of steganographical security techniques and how it has been applied, is applied and will continue to be applied in maintaining confidentiality between two communication parties
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos meaning "covered, concealed, or protected", and graphein meaning "writing".
The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages appear to be (or be part of) something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a shared secret are forms of security through obscurity, whereas key-dependent steganographic schemes adhere to Kerckhoffs's principle.
The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messagesâno matter how unbreakableâarouse interest, and may in themselves be incriminating in countries where encryption is illegal.Thus, whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message.
Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size. For example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it.

Steganography and Its Applications in SecurityIJMER
Â
ABSTRACT: Steganography is the dark cousin of cryptography, the use of codes. While cryptography provides privacy,
steganography is intended to provide secrecy. Steganography is a method of covertly communicating. Steganography is a
process that involves hiding a message in an appropriate carrier for example an image or an audio file. The carrier can then
be sent to a receiver without anyone else knowing that it contains a hidden message. This is a process, which can be used for
example by civil rights organizations in repressive states to communicate their message to the outside world without their
own government being aware of it. In this article we have tried to elucidate the different approaches towards implementation
of Steganography using âmultimediaâ file (text, static image, audio and video). Steganalysis is a newly emerging branch of
data processing that seeks the identification of steganographic covers, and if possible message extraction. It is similar to
cryptanalysis in cryptography. The technique is ancient emerging monster that have gained immutable notice as it have
newly penetrated the world of digital communication security. Objective is not only to prevent the message being read but
also to hide its existence.

Data Security Through Crypto-Stegano Systemsrinzindorjej
Â
Unauthorized access and hacking are major issues for internet users, and numerous articles have been published on various approaches to solving this issue. This study proposes a novel method for encoding a hidden message within the text by combining text steganography and substitution cryptography. While steganography and cryptography can be used to protect data, neither is sufficient to provide better security as they can be broken by steganalysis and cryptoanalysis. Therefore, the terms "cryptography-stegano" should be combined for improved security. In this method, data is first encrypted using a substitution cryptography technique to produce the cypher text, which is then encrypted using text steganography to produce a more secure cypher text sent to the recipient. Contrary to popular belief, using image steganography and cryptographic methods is unnecessary for effective data encryption. The study shows that combining text steganography with cryptographic techniques is an excellent data security method. Additionally, other combinations, such as audio and video steganography, should also be considered for better security

Steganography Technique of Sending Random Passwords on Receiverâs Mobile (A N...IOSR Journals
Â
Abstract: Steganography is the art of hiding the fact that communication is taking place, by hiding information
in other information. There are many application of Steganography with different carrier file format. Here we
perform Steganography Technique with sending OTP on receiver mobile, which is one of the best secured
technique in current scenario. This technique is hiding file information into image with OTP password that is
only known by receiver. And can decrypt using that OTP only this is pure Steganography. Pure Steganography
means that there is none prior information shared by two communication parties. We are not sharing OTP
information by two communication parties. So this is more secure than other technique.
Key Words : Steganography, OTP, ICT, Password, IP, UDP, SIHS, LSB.
With computers having GHz of processing speed, information / data either stored or in
transmission has become more and more vernalable to hostile eavesdropping, theft,
wiretapping etc. This urges us to devise new data hiding techniques to protect and secure data
of vital significance. Steganography is a method of securing data by obscuring the contents in
another media (called Cover) in which it is saved / transmitted. This doctorial thesis proposal will
present a new Steganographic Technique for hiding data in (ASCII) text files together with its
Software implementation, a research area in Steganography which is considered as
toughest among all, to address.
A Novel Steganography Technique that Embeds Security along with CompressionCSCJournals
Â
Problem faced by todayâs communicators is not only security but also the speed of communication. This paper provides a mechanism that increases the speed of communication by reducing the size of content; for this data compression method is used and security factor is added by using Steganography. Firstly, the focus has been made on Data Compression and Steganography. Finally, proposed technique has been discussed. In Proposed technique first data is compressed to reduce the size of the data and increase the data transfer rate. Thereafter on compressed data state table operation is applied to improve the security. Then, this is used as the input to the LSB technique of Steganography. At receiver end, firstly the LSB extraction technique is used, thereafter the state table operation in reverse form is applied and finally the original data is obtained. Hence our proposed technique is effective that can reduce data size, increase data transfer rate and provide the security during communication.

objective of Stegnography is to conceal messages inside other risk-free messages in a manner that does not agree to any enemy to even
sense that there is any second message present. Nowadays, it is an emerging area which is used for secured data transmission over any
public medium such as internet. In this research a novel approach of image stegnography based on LSB (Least Significant Bit)
insertion and cryptography method for the lossless jpeg images has been projected. This paper is comprising an application which
ranks images in a users library on the basis of their appropriateness as cover objects for some facts. Here, the data is matched to an
image, so there is a less possibility of an invader being able to employ steganalysis to recuperate the data. Furthermore, the application
first encrypts the data by means of cryptography and message bits that are to be hidden are embedded into the image using Least
Significant Bits insertion technique. Moreover, interpolation is used to increase the density
Steganography is a technology used since years for the communication of messages secretly. These secret messages are put inside honest carriers. Carriers can be digital images, audio files, video files and so on. The limitation in sending concealed longer messages has been overcoming by the inclusion of video files as carriers. Popular internet services such as Skype, BitTorrent, Google Suggest, and
WLANs are targets of information hiding techniques. Nowadays, plotters are not only using the carriers but also the protocols for communication that regulate the path of the carrier through the Internet. This technique is named Network Steganography.
