Evaluation of LSB Based Image Steganography Technique for various File Formats

2015

Steganography is derived from the Greek word steganos which literally means “Covered” and graphy means “Writing”, i.e. covered writing. Steganography is the art and science of hiding messages in such a way that no one apart from sender and receiver identify the message. The paper describes the steganalysis technique for the detection of secret message in the image. The strong and weak point of this technique is mentioned briefly. Steganography function is used to hide a secret message in any media such as text, image, audio and video. There are many algorithms used for hiding the information. One of the simplest and best known techniques is Least Significant Bit (LSB). This paper focuses on image Steganography and hiding the message in the Least Significant Bit (LSB) method. We also discuss the LSB method used for various file formats. KeywordsCryptography, Steganography, Steganalysis, LSB (Least Significant Bit), GIF, PNG, BMP.

The rapid development of data transfer through internet has made it easier to send the data accurate and faster to the destination, but in order to transfer the data securely to the destination without any modifications, there are many approaches like steganography. This paper introduces the concept of steganography using a new Algorithm "Enhanced LSB Algorithm", which has negligent distortion as compared to the Least Significant Bit Algorithm.

MESSAGE SECURITY USING CRYPTOGRAPHY AND LSB ALGORITHM OF STEGANOGRAPHY

In this paper, a new approach of information security is discussed. In which, Cryptography and Steganography are used as integrated part along with newly developed enhanced security module. In Cryptography, AES algorithm is being used to encrypt a message, and in Steganography we are using LSB (Least significant Bit) method to hide the message in an image object. The proposed system is experimented on various scenarios in order to evaluate its performance. In all the cases, proposed system exhibits satisfactory results.

Design and Implementation of a Steganographic System using the Least Significant Bit Algorithm

African Journal of Computing & ICT, 2019

Secure data transmission over communication channels has been a critical issue since the beginning of the digital era. Due to advances in ICT, most of information is kept electronically. Consequently, the security of information has become a fundamental issue. Besides cryptography, steganography can be employed to secure information. Steganography is similar but adds another dimension to Cryptography. In cryptography, an intruder is normally aware that data is being communicated, because they can see the coded/scrambled message while in steganography, an unintended recipient or an intruder is unaware of the fact that observed data contains hidden information. In this method, people not only want to protect the secrecy of an information by concealing it, but they also want to make sure any unauthorized person gets no evidence that the information even exists. An example is invisible watermarking; although, this technique is not new, its application has been exploited in various information security technologies. This paper shows the design and implementation of a software system that uses the new image steganographic approach. This approach makes use of Least Significant Bit (LSB) algorithm and is implemented through the Microsoft.NET framework. This software is applied in embedding data into a bit map image (.bmp).

An Overview of Image Steganography using LSB Technique

International Journal

Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet. For hiding secret information in images, there exists a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. This paper intends to give an overview of image steganography, its uses and techniques. For a more secure approach, this paper encrypts the message using secret key and then sends it to the receiver. The receiver then decrypts the message to get the original one. The rapid development of data transfer through internet made it easier to send the data accurate and faster to the destination. This paper deals with the algorithm based on hiding a large amount of data (image, audio, text) file into color BMP image. This project gives a brief idea about the image steganographic approach that make use of Least Significant Bit(LSB) algorithm for embedding the data into the bitmap image(.bmp) which is implemented through the JDK 1.5.0_07 environment. The Least Significant Bit (LSB) embedding technique suggests that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden image in the cover file.

LSB Based Image Steganography for Information Security System

International Journal of Trend in Scientific Research and Development, 2018

Information hiding in a cover file is one of the most modernized and effective ways for transferring secret message from sender to receiver over the communication channel. There are many steganographic techniques for hiding secret message in image, text, audio, video and so on. Image Steganography is also one of the common methods used for hiding the information in the cover image. In this research work, the secret message is hidden in a cover image file using image steganography. LSB is very efficient algorithm used to embed the information in a cover file. The LSB based image steganography with various file sizes is analyzed and illustrated their results. Bitmap (*.bmp) image is used as a cover image file to implement the proposed system. The detail Least Significant Bit (LSB) based image steganography is introduced. In this paper, the new embedding algorithm and extracting algorithm are presented. While embedding the secret message in a cover image file, the starting embedded pixel is chosen according to public shared key between sender and receiver. The original cover image and embedded image with secret message are analyzed with PSNR values and SNR values to achieve security. The resulting embedded image shows the acceptable PSNR and SNR values while comparing with the original cover image. The proposed system can help the information exchanging system over communication media.

Image Steganography Using Least Significant Bits (LSBs): A Novel Algorithm

Steganography plays a major role in data communication security. It focuses on hiding the fact that communication is taking place by hiding information in other information. The least significant bit (LSB) based approach is a popular type of steganographic algorithms in the spatial domain. The advantage of LSB is its simplicity to embed the bits of the message directly into the LSB plane of cover-image and many applications use this method. Images are the most popular cover objects used for Steganography. In this paper, we introduce a novel secure algorithm for color image steganography using least significant bits (LSBs). The security of our algorithm comes from using a key (the stego key) which is an array of 32 integers chosen randomly from Z24. The first pixel position, where we start hiding process, is computed based on this stego key. https://sites.google.com/site/ijcsis/

An Effective Way of using LSB Steganography in images along with Cryptography

International Journal of Computer Applications, 2014

Hiding data is a very important thing nowadays as the data travels over various unsecure networks. To avoid this problem cryptography is used which hides the data or scrambles your message, but cryptography alone cannot provide total security as the message is still available to perform cryptanalysis. Steganography hides the existence of the message. Most of the peoples use either cryptography or steganography to improve security. But a combination of both the techniques provides better security. This paper will describe an effective way of using cryptography along with a modification in LSB steganography in images.

A Comprehensive Image Steganography Tool using LSB Scheme

International Journal of Image, Graphics and Signal Processing, 2015

As a consequence of the fact, transmitting data has been fast and easy these days due to the development of the Internet. Where internet is the most important medium for confidential and non-confidential communications. Security is the major matter for these communications and steganography is the art of hiding and transmitting secret messages through carriers without being exposed. This paper presents a secured model for communication using image steganography. The main concern is to create a Java-based tool called IMStego that hides information in images using Least Significant Bit (LSB) algorithm (1-LSB) and modified Least Significant one Bit algorithm, i.e. Least Significant 2 Bits algorithm (2-LSB). IMStego is a more comprehensive security utility where it provides user-friendly functionality with interactive graphical user interface and integrated navigation capabilities. It provides the user with two operations, which are hiding secret data into images and extracting hidden data from images using 1-LSB or 2-LSB algorithm. IMStego tool hides secrete information in color static images with formats BMP and PNG.

A Development of Least Significant Bit Steganography Technique

Iraqi Journal of Computers, Communication and Control & System Engineering (IJCCCE), 2020

Recently, the world has been interested in transferring data between different devices. The transmission of data must be encrypted so that the intended receiver can only read and process a secret message. Hence, the security of information has become more important than earlier. This paper proposes the least significant bit Steganography method to hide a secret message inside an image cover via using dynamic stego-key. To check the effectiveness of the proposed method, many factors are used for evaluation and compared with another method. The results illustrate more robustness at steganography since stego-key depends on the cover image to hide a secret message.
