From information Security to Steganography
Abstract— Digital communication has become an essential part of infrastructure nowadays, a lot of applications are Internet-based and it is important that communication be made secret. As a result, the security of information passed over an open channel has become a fundamental issue and therefore, the confidentially and data integrity are required to protect against unauthorized access and use. This has resulted in an unstable growth in the field of information hiding. In a modern era of Information Technology, illicit copying and illegal distribution accompany the adoption of widespread electronic distribution of copyrighted material. This is the main reason why people think about how to protect their work and how to prevent such unlawful activities. For this purpose various methods including cryptography, steganography, Digital signature, coding and so on have been used. Steganography is the best suited technique that allow user to hide a message in another message (cover media). Most of steganography research uses cover media as pictures, video clips, text and sounds. This paper focuses on the various techniques in steganography to enhance the security of communication over an open channel.
Steganography is the art of Hiding Data
Steganography has been derived from the Greek word Steganous (covered, concealed or protected) and Graphie (writing) which means “covered writing”. It is the process of hiding a secret message with an ordinary message. Which when viewed by someone else will be able to see only the ordinary message they will fail to identify that it contains a hidden or encrypted message. The hidden message can be extracted once it reaches its destination. Steganography is now gaining popularity among the masses because of ease in use and abundant tools available. In this paper, the emphasis is given on the basic technique used to implement Steganography and also how to extract the data and check whether the file received by the reader carries some hidden message. Paper also depicts various tools available for the same.
Steganography: The Art of Covert Communication
2015
This paper presents a base study of Steganography. Steganography is an important area of research in recent years involving a number of applications. In another words we can say that it is technique of hidden communication in which existence of secret hidden remains invisible. Here we have critically compared various information security methods and also have covered Steganography overview, its major types, classification with less detail of Steganalysis, which is the art and science of defeating Steganography.
With the growth of communication over computer networks, how to maintain the confidentiality and security of transmitted information has become an important issue. In order to transfer data securely to the destination without unwanted disclosure or damage, nature inspired hide and seek tricks such as, cryptography and Steganography are heavily in use. Just like the Chameleon and many other bio-species those change their body color and hide themselves in the background in order to protect them from external attacks, Cryptography and Steganography are techniques those are used to encrypt and hide the secret data inside other media to ensure data security. This paper discusses the concept of a simple spatial domain LSB Steganography that encrypts the secrets using Fibonacci-Lucas transformation before hiding for better security.
Steganography a New Dawn in the World of Information Security Compared with Cryptography Technology
Throughout thousand ages the need for secure communication and private conversation has led to the invention of Cryptography. The word Cryptography is combination of the Greek words (kryptó), which means "hidden"; and (graphein), which means "writing", it is the act of having secure communication in the presence of third party called adversary. On the other hand Steganography is to conceal a secret message or image within another message and to extract this secret message only at its destination, the word steganography combines the Greek words (steganos), which means "concealed", and (graphein) which means "writing". While cryptography is the protection of a message contents alone, steganography is concerned with concealing the contents of a secret message, so steganography improves cryptography by hiding an encrypted message so that no one will suspect its existence. The main goal of steganography is to communicate securely in a completely undetectable manner and to avoid drawing suspicion to the transmission of a hidden data. It is not to keep others from knowing the hidden information, but it is to keep others from thinking that the information even exists. Thousands of years ago cryptography began by the application of codes and ciphers to protect secret messages, by the beginning of 20th century the invention of complex machines, such as the Enigma rotor machine, have provided more sophisticated ways of encryption; and subsequently introduction of computer systems has increased the efficiency and complexity of encryption. Nowadays modern digital Steganography became more sophisticated than the cryptography, allowing a user to hide large amounts of information within image or audio files. These forms of steganography are often used in conjunction with cryptography so that the information is doubly protected; first it is encrypted and then hidden so an adversary has to find the information first and then decrypt it. Researches are still underway to develop this technology and use it to protect the information in all fields. This paper is a trial to know and understand the Steganography as a technology and to make a comparison between cryptography and steganography.
Comparative study of different steganographic techniques
2011
Abstract:-Steganography is the method of hiding data in such a way that no one, except the sender and the intended recipient, expects the existence of the hidden data. Thus the goal here is always to conceal the very existence of the secret data embedded in an innocent data in such a way that it will be undetectable, robust and the innocent data should be able to accommodate high capacity of the secret data.
― STEGANOGRAPHY AND ITS IMPACT ON IT ‖ Ms
This paper describes the steganography and its impact on information technology. All over the world we have to transfer the information. This has been done only due to the invention of technology. But the most important is the privacy of the information. Steganography is a technique to make the data private. This helps in hiding the data from unauthorized persons. Data can be hidden in any content like audio, video or
A CLOSER LOOK AT CATEGORIES OF STEGANOGRAPHY TECHNIQUES
The cryptography and steganography are techniques to provide information security. Both of these techniques are vulnerable to different kinds of attacks. It is obvious that the success rate of an attack is higher in the case of the former since it discloses the very presence of the content though it is encrypted. Why the success rate is high in case of cryptography is associated with human psychology. It prompts man to find out something when the presence of the same is known and hence it can be said that cryptography is more vulnerable to attack than steganography. This attracts researchers and students to select steganography as their area when information security is the matter of concern. This chapter describes the complete details of categories of steganography techniques that can open the door for entering into the world of steganography where secret is embedded in seemingly innocuous cover medium.
Different Medias of Steganography-An Emerging Field of Network Security
2012
Steganography, literally meaning “secret writing”, involves hiding a data file in another innocuous-looking file. From the time of Herodotus in Greece, to the defense mechanisms of today, steganography has been used to deny one’s adversaries the knowledge of message traffic. Steganography takes one piece of information and hides it within another. A “container file” holds the secret message in it, in such a way that the existence of the message cannot be suspected. This could be done in several possible ways, with newer methods being discovered with each passing day. In this paper, a detailed analysis of steganography is made. The history of steganography is briefly dealt with. How steganography works is examined, keeping in mind Bender’s specifications. Data hiding is implemented in three different media; text, audio and image files. Each offers challenges and solutions to these challenges are analysed. How they is implemented using steganographic tools is also seen. The main chara...
A comprehensive study of steganography: A method of hiding information in other information
Steganography is a art of communicating by hiding a type of information in other information.In the present era, the more attention is given to the art of displaying and sending hidden information because of security purpose.Therefore, different methods have been proposed so far for hiding information in different cover media. In this review paper, we are highlights the various study and research done before.Steganography's primary goal is to hide data within some other data such that the hidden data cannot be detected even if it is being sought.A lot of researchers has done tremendous work in this art but there is lack of a single means to concrete all the information in single study.This paper aims to fulfill that dearth.
