INTRODUCTION STEGANOGRAPHY Steganography is an art of hiding data inside data.Steganography is a form of security technique which is used to hide secret messages in various types of files, including digital images, audio and video. It is very old way of hiding secret data, but it changes a lot with the introduction of new technologies. There are many techniques available today for hiding secret data. For hiding in different cover media, there are different techniques. The main aim of steganography is to

project deals with detection of steganography content. Steganography is the additional method in cryptography which helps to hide the coded message inside pictures, audio or videos. To hide the message is important but to reveal such content is more important to avoid usage by criminals. This project applies an approach of supervised machine learning to detect the presence of steganographic content coded by programs like Steghide in the images.

CHAPTER 1 INTRODUCTION STEGANOGRAPHY Steganography is the art or practice of hiding a message, picture, or document inside another message, picture, or file. The term steganography is derived from the Greek words- stegano means "covered or else protected", in addition graphed signifies "writing" and combining these two Greek words defining it as “covered writing” [1]. Steganography is used to conceal the messages inside other harmless messages in a way that does not allow any enemy to even sense

use of steganography which is a technique of hiding information in digital media. In contrast to cryptography, it doesn’t keep others interpreting the hidden

ABSTRACT: Steganography is the art and science of sending covert messages such that the existence and nature of such a message is only known by the sender and intended recipient. Steganography has been practiced for thousands of years, but in the last two decades Steganography has been introduced to digital media. Attacks, misuse or unauthorized access of information is of great concern today which makes the protection of documents through digital media is a priority problem. It is the art of hiding

Abstract : Steganography is the methodology in science that involves communicating secret data in an appropriate multimedia carrier for e.g. video, audio and image files. Audio steganography hides data in a audio signal which is a cover signal without any modification in that cover signal. Generally, Steganography concept is confused with other technique such as cryptography and watermarking, but objectives such as imperceptibility, capacity of hidden data and robustness draws thin line between them

cryptography or steganography. Steganography is a secret communication method for hiding data in some digital media such as images, audio etc. Hiding secret data using audio files as carrier is known as “Audio Steganography”. Moreover, MP3 files being more popular can be good message carriers. With the advancement in digital audio media, many audio steganography

com Vanitha Lakshmi.M2 Research Scholar S.A. Engineering College Chennai, India vanithahitesh08@yahoo.co.in Abstract—In various areas, information security is very important due to the development of high speed computer networks and internet. Steganography is developed as a technique for securing the secrecy of communication. In this paper, the secret information are directly hidden in the original video in a random order by using linear feedback shift register method that generates the pseudo random

communication experts [6]. Steganography (SG) is one of many techniques used to overcome this threat. [16] It is an art of hiding the existence of communication, in contrast to cryptography. Basically it’s a method of concealing the information in ways that prevents the detection of hidden information. We should encrypt our information before communicating. By doing this, even if the message is being found, the intruder won’t be able to learn what we are trying

Solanki PG student,Computer Engineering Sarvajanik College of Engineering Technology Surat, India roshanisolanki23@gmail.com Abstract— In today’s era, due to advancements in the field of information technology, the need for information security is highly increasing day by day. Steganography plays a major role in secret data communication. It is nothing but to communicate in such a way that not only the contents are hidden but also the existence

Steganography Techniques Using Cryptography-A Review Paper Himanshi Sharma MTech(CSE) IInd Year E-Max College of Engineering and Technology Ambala, Haryana, India Email Id: cute.himanshi29@gmail.com Abstract: The two important aspects of security that deal with transmitting information or data over some medium like internet are cryptography and steganography. Cryptography results in converting plain text into cipher text which is in unreadable or in non-explanatory form, difficult to be guessed

A Survey of Different Steganography Techniques Abstract Steganography is defined as the study of invisible communication. It usually deals with the ways of hiding the existence of the communicated data in such a way that it remains confidential. It maintains secrecy between the two communicating parties. The main objectives of steganography are high capacity of the hidden data, perceptual transparency (invisibility), temper resistance, undetectability, computation complexity and robustness. It

forensics community. 2.4 Challenges of Digital Forensics Digital technology evidence gathering and presentation presents challenges that are inherently different from other kinds of forensic investigations in other fields. Digital evidence is different from evidence that has been created, stored, transferred and reproduced from non-digital formats (Chaikin, 2004). In his study, he showed that the main difference between digital technology evidence and other forms of forensic science practice is

education to digital forensic investigations to develop better and efficient tools to overcome the anti forensic packages. The future of this project could be extended to implement many other anti forensic techniques and features like encryption, steganography and even targeting computer forensic tool vulnerabilities. It would be a disaster if all these techniques are combined and implemented. The future developments could also make use of other digital forensic tools like Prodiscover, Encase and also

Rainbow table: It is a pre computed table for reversing cryptographic hash functions, usually for cracking password hashes. Tables are usually used in recovering a plaintext password up to a certain length consisting of a limited set of characters. Ransaomware: The system that doesn’t allows users to proceed until the payment is done is generally known as Ransaomware. RAT programmes: RAT stands for ¨Remote Administrative Tool¨, it is a malware software, that allows a remote operator to control

The Internet is not safe. The Internet promotes bullying. The Internet is non-communicative. The Internet has zero privacy. The Internet is creating illiterate teenagers. These are just some of the responses many parents and adults say to their children when asked "What's so wrong with the Internet?" danah boyd (chose to style her name in lower case) attempts to shut down all of these statements in her book "It's Complicated: The Social Lives of Networked Teens." In boyd's book, she provides 10 years

helping to anticipate the unauthorized actions shown to be disruptive to planned operations”. This definition is generally accepted to be an all-inclusive definition. [6] Willassen and Mjølsnes (2005) defined digital forensics as “the practice of scientifically derived and proven technical methods and tools towards the after-the-fact digital information derived from digital sources for the purpose of facilitating or furthering the reconstruction of events as forensic evidence”. [6] The main difference

1. Evaluate the issues which arise when first responders (police or paramedics) are called to a crime scene, which (prior to their arrival) is discovered to be a source of digital crime. What complexities are likely to arise that would compromise the investigation and prosecution of alleged perpetrators? Unit 3. Many criminal investigations will include computers at some point in a case. Murder and rape suspects, through a search warrant, may have their email and Internet activities analyzed
