What is STEGANOGRAPHY? What does STEGANOGRAPHY mean? STEGANOGRAPHY meaning & explanation
What is STEGANOGRAPHY? What does STEGANOGRAPHY mean? STEGANOGRAPHY meaning - STEGANOGRAPHY pronunciation - STEGANOGRAPHY definition - STEGANOGRAPHY explanation - How to pronounce STEGANOGRAPHY? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. 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 messages—no matter how unbreakable—arouse 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. Discussions of steganography generally use terminology analogous to (and consistent with) conventional radio and communications technology. However, some terms show up in software specifically, and are easily confused. These are most relevant to digital steganographic systems. The payload is the data covertly communicated. The carrier is the signal, stream, or data file that hides the payload—which differs from the channel (which typically means the type of input, such as a JPEG image). The resulting signal, stream, or data file with the encoded payload is sometimes called the package, stego file, or covert message. The percentage of bytes, samples, or other signal elements modified to encode the payload is called the encoding density, and is typically expressed as a number between 0 and 1. In a set of files, those files considered likely to contain a payload are suspects. A suspect identified through some type of statistical analysis might be referred to as a candidate.

Stegospolit - Exploit Delivery With Steganography and Polyglots
by Saumil Shah "A good exploit is one that is delivered with style." Stegosploit creates a new way to encode "drive-by" browser exploits and deliver them through image files. These payloads are undetectable using current means. This talk discusses two broad underlying techniques used for image based exploit delivery - Steganography and Polyglots. Drive-by browser exploits are steganographically encoded into JPG and PNG images. The resultant image file is fused with HTML and Javascript decoder code, turning it into an HTML+Image polyglot. The polyglot looks and feels like an image, but is decoded and triggered in a victim's browser when loaded. The Stegosploit Toolkit v0.3, to be released with improvements upon existing v0.2, contains the tools necessary to test image based exploit delivery.

DEF CON 21 - Michael Perklin - ACL Steganography Permissions to Hide Your Porn
ACL Steganography - Permissions to Hide Your Porn MICHAEL PERKLIN SECURITY RESEARCHER Everyone's heard the claim: Security through obscurity is no security at all. Challenging this claim is the entire field of steganography itself - the art of hiding things in plain sight. Most people know you can hide a text file inside a photograph, or embed a photograph inside an MP3. But how does this work under the hood? What's new in the stego field? This talk will explore how various techniques employed by older steganographic tools work and will discuss a new technique developed by the speaker which embodies both data hiding and data enciphering properties by encoding data inside NTFS volumes. A new tool will be released during this talk that will allow attendees to both encode and decode data with this new scheme. Michael Perklin (@mperklin) is currently employed as a Senior Investigator within the Corporate Investigations department of an Enterprise class telecommunications firm. Throughout his career he has performed digital-forensic examinations on over a thousand devices and has processed petabytes of information for electronic discovery. Michael has spoken at security conferences internationally about a variety of topics including digital forensics, computer security, data hiding, and anti-forensics. Michael holds numerous security-related degrees, diplomas and certifications, is a member of the High Technology Crime Investigations Association, and is an avid information security nut who loves learning about new ways to break things.

Image encryption and embedding in image Matlab
This code reads raw text from an input notepad. It is then encrypted using RSA encryption algorithm. This encrypted text is then hidden in the 8 bit planes of an input grayscale image. This image is then read back, embedded encrypted text from the bit planes are read back, it is then decrypted, then the resulting raw text is displayed. MSE PSNR between original image and encrypted text embedded image is shown. Code will work for any amount of text in the input notepad. There is no limitation. Code can be modified based on customer requirements. If you are interested in buying this code, please drop an email to [email protected], or please visit matlabz.com

Text Steganography : Hindi Tutorials
Steganography is the science of hiding information. Whereas the goal of cryptography is to make data unreadable by a third party, the goal of steganography is to hide the data from a third party. In this article, I will discuss what steganography is, what purposes it serves, and will provide an example using available software.

With all the data breaches lately, it's likely that the password of one of your accounts has been compromised. Hackers now might know the password you've used, but they also might not.. To understand why, we'll take a look at what methods a company can use to protect user passwords. We'll take a look at encryption, hash functions and a multilayer approach! 📚 Sources Can be found on my website: https://savjee.be/videos/simply-explained/hash-functions/ 🌍 Social Twitter: https://twitter.com/savjee Facebook: https://www.facebook.com/savjee ✏️ Check out my blog https://www.savjee.be
CERIAS Security: John Oritz: Steganography 5/6
Clip 5/6 Speaker: John Oritz · SRA International Steganography is a discipline of computer science whose aim is to conceal the existence of information. Steganography synergizes various technologies including data compression, digital signal processing, information theory, data networks, cryptography, coding theory, and the human audio and visual system. Strap on your seatbelt. I will present some key concepts of steganography, describe a number of basic and advanced spatial and transform domain techniques (with lots of pictures and sounds for the attention-challenged), and demonstrate these techniques using custom steganography software. The demonstrations include a Least Significant Bit (LSB) technique, High-Capacity Hiding in Jpegs, and time modulation in audio. For more information go to the Cerias website (http://bit.ly/dsFCBF)

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Steganalysis is the study of detecting messages hidden using steganography; this is analogous to cryptanalysis applied to cryptography. The goal of steganalysis is to identify suspected packages, determine whether or not they have a payload encoded into them, and, if possible, recover that payload. Unlike cryptanalysis, where it is obvious that intercepted data contains a message (though that message is encrypted), steganalysis generally starts with a pile of suspect data files, but little information about which of the files, if any, contain a payload. The steganalyst is usually something of a forensic statistician, and must start by reducing this set of data files (which is often quite large; in many cases, it may be the entire set of files on a computer) to the subset most likely to have been altered. The problem is generally handled with statistical analysis. A set of unmodified files of the same type, and ideally from the same source (for example, the same model of digital camera, or if possible, the same digital camera; digital audio from a CD MP3 files have been "ripped" from; etc.) as the set being inspected, are analyzed for various statistics. Some of these are as simple as spectrum analysis, but since most image and audio files these days are compressed with lossy compression algorithms, such as JPEG and MP3, they also attempt to look for inconsistencies in the way this data has been compressed. For example, a common artifact in JPEG compression is "edge ringing", where high-frequency components (such as the high-contrast edges of black text on a white background) distort neighboring pixels. This distortion is predictable, and simple steganographic encoding algorithms will produce artifacts that are detectably unlikely. One case where detection of suspect files is straightforward is when the original, unmodified carrier is available for comparison. Comparing the package against the original file will yield the differences caused by encoding the payload—and, thus, the payload can be extracted. In some cases, such as when only a single image is available, more complicated analysis techniques may be required. In general, steganography attempts to make distortion to the carrier indistinguishable from the carrier's noise floor. In practice, however, this is often improperly simplified to deciding to make the modifications to the carrier resemble white noise as closely as possible, rather than analyzing, modeling, and then consistently emulating the actual noise characteristics of the carrier. In particular, many simple steganographic systems simply modify the least-significant bit (LSB) of a sample; this causes the modified samples to have not only different noise profiles than unmodified samples, but also for their LSBs to have different noise profiles than could be expected from analysis of their higher-order bits, which will still show some amount of noise. Such LSB-only modification can be detected with appropriate algorithms, in some cases detecting encoding densities as low as 1% with reasonable reliability. Detecting a probable steganographic payload is often only part of the problem, as the payload may have been encrypted first. Encrypting the payload is not always done solely to make recovery of the payload more difficult. Most strong ciphers have the desirable property of making the payload appear indistinguishable from uniformly-distributed noise, which can make detection efforts more difficult, and save the steganographic encoding technique the trouble of having to distribute the signal energy evenly (but see above concerning errors emulating the native noise of the carrier). If inspection of a storage device is considered very likely, the steganographer may attempt to barrage a potential analyst with, effectively, misinformation. This may be a large set of files encoded with anything from random data, to white noise, to meaningless drivel, to deliberately misleading information. The encoding density on these files may be slightly higher than the "real" ones; likewise, the possible use of multiple algorithms of varying detectability should be considered. The steganalyst may be forced into checking these decoys first, potentially wasting significant time and computing resources. The downside to this technique is it makes it much more obvious that steganographic software was available, and was used. ....

Trovisto Conducts a Live Hacking Using Cryptography [VIDEO]
SECURITY FIRM Trovisto has showed how hackers could exploit user data from victims' machines using cryptography. Demoing the walkthrough Trovisto's Co-Founder, Marcel Kouame, explained how hackers hide large volumes of data in seemingly innocent files to steal of source code from a business, for example. In the demo, Kouame shows how slightly reducing the quality of an image can leave space to hide as secret pattern using a freeware steganography tool called Openpuff, which will replace the original image on the victim's computer and steal the required data.
