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.

Review of vital techniques for hiding confidential data using image steganography

Journal of emerging technologies and innovative research, 2018

The quick advancement in the exchange of information through internet made it easier to exchange information exact and faster to the receiver. Security of data is one of the huge components of information technology and communication. Steganography is a term used for information hiding and it is an art of hidden writing. In steganography we hide information with a multimedia carrier i.e. image, text, audio, video files, etc. So, that observer cannot find the hidden information which we want to send to the receiver. Steganography main objective is to provide robustness, detectability, capacity of hidden data due to which it differs from other techniques such as watermarking and cryptography. This paper proposes a various technique used to hide information on image by an image steganography. In image steganography we hide our secret data in image so that the observer cannot feel its existence. Image steganography strategies are as of late been useful to send any secret message in the ...

Steganographical Techniques in Hiding Text Images – System

International Journal of Recent Technology and Engineering (IJRTE), 2019

In this era, internet has become a widespread entity all over the world. Sharing and communicating images, video contributes an essential role in this scientific era. In the meanwhile, secure transition of data has indeed become a major issue. Steganography is one of technology that contributes a vital role in protecting the secret data against an unauthorized access. In this type, secret data can be concealed into a cover file that includes audio, video, text and also image. In this paper, we propose different types of steganography methods for secure transfer of data in a confidential manner. The paper also explores stenographical techniques in terms of text, image and audio. The proposed work compares and discusses the stenographical methods in spatial domain, frequency domain derived under the image technique.

Digital Image Steganography

international journal for research in applied science and engineering technology ijraset, 2020

Steganography is the practice of concealing the truth that communication is taking place. Intruders can easily attack information within a system if it is readily available. It can be read, modified, misused, and revealed to others. Therefore, the goal is to hide the existence of the secret data. Using steganography techniques, secret data can be concealed within an appropriate multimedia carrier, such as, image, audio, text files; among which digital image is the most widely used carrier format. Different steganography techniques are available, some are more advanced than the others, having strong and weak points respectively. The suitable technique can be selected as per the application requirement. The main objectives of steganography are undetectability, untraceable, robustness, and capacity of secret data. These are the factors that make it different from techniques such as cryptography. This paper analysis the uses of steganography and its techniques. It additionally aims to determine which steganography technique is more suitable for a certain application.

A Survey of Various Image and Audio Steganographic Techniques

Now days sharing information over the internet has become a matter of major concern, as one has to share data over internet for various uses, which requires strong information protection techniques. Thus, cryptography is present is used for protecting data but a potential technique which provides enough security is required. Various data hiding techniques were present but steganography provides security lot more than other techniques. Steganography actually protects information by hiding information in the original messages. This paper presents a comparison between cryptography and steganography, also presents an overview of various image steganography techniques with their advantages and disadvantages which helps in data hiding.
