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.

CRYPT STEGO : A new paradigm in information security
 
20:30
We live in the INTERNET era. With the advent of internet, the world has become a global village. Nowadays, most of the communications are taking place only through internet. Electronic medium plays a vital role among all other media. When information is sent through internet, it is available to the entire universe and its security becomes a big question mark. Hence secured communication becomes an important topic of interest. Protection and availability are the two major aspects of secured communication. This video explains a new technique called crypt-stego to enhance information security. It is a hybrid method of two techniques cryptography and steganography. This new method enhances security by protecting the information using the method of cryptography and making it available only to the intended recipient by the method of steganography.

Encryption Key Distribution Applying Steganography
 
00:41
The quondam problem of key distribution for symmetric ciphers has been, and still is, an essential element of secure information communications. In this proposed technique, we use ideas originated from steganography to hide the encryption key in the transmitted cipher text itself. The method begins by dividing the encryption key into an agreed-upon number of sub-keys. These sub-keys are concealed in the cipher text using a set of locations, known only to the sender and the receiver, as a shared secret. Then one transmits the resulting slightly longer message to the receiver where he or she can retrieve the key and decrypt the original message. We conjecture that since the cipher text is a set of pseudo-random bits, embedding the pseudo-random bits representing the key will not be traceable. The proposed approach is suitable for both software and hardware implementations.

What is STEGANALYSIS? What does STEGANALYSIS mean? STEGANALYSIS meaning - STEGANALYSIS pronunciation - STEGANALYSIS definition - STEGANALYSIS explanation - How to pronounce STEGANALYSIS? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. 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. ....

How to hide text behind image 2016-17 | Steganography on mobile 2017
 
04:48
Hello Friends this video show you how to hide text behind your image by using Stenography method with Android application "Steganography Master". data encryption or encoding and data decryption or decoding are perform by this application This Application using steganography decoder to decode the text behind image as well as steganography encoder to encode the text behind image Have you ever wanted to hide a secret message inside a photo? With Steganography Master, you can encode a message in a picture and then save it or send it to a friend. The message can only be decoded using the same app, but if you want to ensure that only the intended receiver can read the message, you can also provide a password. App download link: https://play.google.com/store/apps/details?id=com.dinaga.photosecret&hl=en ******************************************************************** What is Steganography? In modern digital steganography, data is first encrypted by the usual means and then inserted, using a special algorithm, into redundant (that is, provided but unneeded) data that is part of a particular file format such as a JPEG image. Think of all the bits that represent the same color pixels repeated in a row. By applying the encrypted data to this redundant data in some random or nonconspicuous way, the result will be data that appears to have the "noise" patterns of regular, nonencrypted data. A trademark or other identifying symbol hidden in software code is sometimes known as a watermark. Recently revived, this formerly obsolete term gained currency in its day (1500) from a work by Johannes Trithemius, Steganographia, ostensibly a system of angel magic but also claiming to include a synthesis of how to learn and know things contained within a system of cryptography. The book was privately circulated but never published by the author because those who read it found it rather fearsome. Techopedia explains Steganography Rather than being incomprehensible to an unauthorized third party, as is the case with cryptography, steganography is designed to be hidden from a third party. Not only must the hidden data be discovered—considered a formidable task in and of itself—it must be encrypted, which can be nearly impossible. One use of steganography includes watermarking which hides copyright information within a watermark by overlaying files not easily detected by the naked eye. This prevents fraudulent actions and gives copyright protected media extra protection. There is some concern, sans definite proof, that the terrorists who plotted and deployed the 9/11 mission in New York City utilized steganography. This is what primarily brought the science of stenography front and center. Data can be stolen and encrypted through a file transfer or, more often than not, through email. And as with what has been suspected for 9/11, steganography can be used for secret communications that deal with terrorist plots. On the lighter side, steganography usage has occurred in the military for decades, even if not computer based. One example was having a secret message was tattooed on a soldier’s shaved head. His hair would of course grow out and, once it did, he would have his hair shaved again only to reveal the hidden tattooed message to the designated recipient. for more info plz visit https://www.techopedia.com/definition/4131/steganography ******************************************************************** Watch our other videos: 1.How to create greeting cards on mobile https://www.youtube.com/watch?v=8053f6eRCLA 2.create your own logo on your mobile https://www.youtube.com/watch?v=LG5pIqZmXFY 3.How to live streaming on youtube by mobile 2016-17 | live streaming on YouTube 216-17 https://www.youtube.com/watch?v=LE5A9hZY4A4 ******************************************************************** Thanks For Watching This Video...

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.

Fast Forensics Using Simple Statistics and Cool Tools JOHN ORTIZ COMPUTER ENGINEER, CRUCIAL SECURITY/HARRIS Ever been attacked by malicious code leaving unknown files all over your computer? Trying to figure out if a file is encrypted or just compressed? Is the file really something else? Is there hidden data? Are you short on time! This talk leads you through file identification and analysis using some custom FREE tools that apply statistics and visualization to answer these questions and more. You can often identify files by their statistical picture and I am going to show you how. We can find some hidden data (steganalysis), easily determine if an executable file is packed or obfuscated, find appended data, figure out if the file is really what it purports to be and even aid in reversing XOR encryption. The final proof of concept program allows you to statistically identify (i.e. no magic numbers or header information used) some file types autonomously for an entire hard drive. The Windows-based tools (mostly math so adaptable to Linux) and source code are free! John Ortiz is currently a senior computer engineering consultant for Harris/Crucial Security Inc. working as a reverse exploit engineer. In this position, he develops and analyzes vulnerabilities and exploits for various software. Prior to working at Crucial, he spent 5 years at SRA International and 5 years at General Dynamics developing various defense related software, researching data hiding techniques, and analyzing malware. In a second role, Mr. Ortiz developed and teaches a Steganography course for the University of Texas at San Antonio (UTSA). It covers a broad spectrum of data hiding techniques in both the spatial and transform domains including least significant bit, discrete cosine transform, echo hiding, hiding in executables, and hiding in network protocols. For the course, Mr. Ortiz developed several steganographic programs for testing and analysis. Mr. Ortiz holds two master's degrees from the Air Force Institute of Technology, one in Electrical Engineering and one in Computer Engineering and a BSEE from Rose-Hulman Institute of Technology.

Brent Dukes Imagine having the capability to covertly send messages to an individual or a larger audience, without the need for large centralized infrastructure where your message could be observed, intercepted, or tampered with by oppressive governments or other third parties. We will discuss the opportunities and challenges with steganography implementations in widely used amateur radio digital modes, and present a proof of concept implementation of hiding messages within innocuous transmissions using the JT65 protocol. This technique could theoretically be used to implement a low cost, low infrastructure, covert, world wide short message broadcasting or point to point protocol. No messages in codes or ciphers intended to obscure the meaning thereof were actually transmitted over the amateur bands during the creation of this talk. Paul Drapeau is currently the Principal Security Researcher for Confer Technologies Inc. He has held senior level IT security roles and consulted on information security topics for various organizations for over 15 years. Paul has a bachelor's degree in computer science from the University of Rhode Island and has been licensed as an amateur radio operator since 1986. Brent Dukes has a decade of experience working in software and systems engineering roles. He spends his nights tied to various hardware hacking projects sitting in pieces all over his lab, and participating in CTFs. His idea of fun is reverse engineering and modifying toys and consumer electronics for the purposes of good. Brent has been a licensed amateur radio operator since 2006.

DEF CON 8 - Bennett Haselton - A protocol that uses steganography to circumvent
 
01:02:51
Bennett Haselton - A protocol that uses steganography to circumvent network level censorship A protocol that uses steganography to circumvent network level censorship. Many trivial techniques are already available for circumventing firewalls and proxy servers that monitor or censor network traffic -- for example, if your firewall blocks CNN, someone could set up an unblocked site outside the firewall where you can type "http://www.cnn.com/" into a form and retrieve the page contents. The problem with these "protocols" is that they make it easy to get caught, if the censors know what to look for -- for example, a GET or POST form field containing "http://" is trivially easy to detect. Even an encrypted protocol would still be easy for censors to detect, without breaking the encryption -- just the fact that you're *using* a tool for circumventing the censors would often be enough to get you in trouble. What we have designed is a protocol that uses steganography to circumvent network-level censorship, so that the protocol is undetectable to censors. We explain why some naive solutions to the problem -- such as hiding information in a long, dynamically-generated URL which is sent to an outside "friendly" site, or hiding information in cookies -- are not steganographically secure. Our protocol hides information in "innocent-looking" text queries that pass through the censoring proxy undetected. The page contents are encrypted and embedded in more "innocent-looking" content that is sent back to the browser. This sounds simple, but the mathematics of using steganography to make a protocol *undetectable* turn out to be infuriatingly complicated. Much of the talk will be devoted to attacks against the system that we didn't consider the first time around, and why more naive solutions may fall to these attacks. Bennett Haselton has been the coordinator of Peacefire.org since its inception in 1996. Peacefire opposes censorship that targets Internet users under 18, and maintains that profanity and smut on the Internet are not, in fact, "dangerous" to anybody, as most lawmakers and blocking software companies have made them out to be. Peacefire publishes research into different Internet censorship programs and technologies, their shortcomings, possible misrepresentations by the companies selling them, and (most popular) how to get around them.

Dalibor Vlaho on Steganography. How to hide something inside an Image File
 
06:23
Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos (στεγανός) meaning "covered or protected", and graphein (γράφειν) meaning "to write". 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, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.
