Hidden in Plain Sight, Steganography & Digital Watermarking | Ryan Fox | Hackers of CypherCon
 
23:46
(S1: E18) Steganography is the practice of hiding a message “in plain sight” inside an image, video, sound, text, or file. The practice goes back centuries, and in recent years has seen a rise in use for digital watermarking. Unlike cryptography, steganography seeks to hide even the presence of a message. Steganography can be used for communication, leak prevention, or copyright protection. We’ll look at steganographic techniques, analysis, and detection through the lens of digital watermarking.

Hardware Implementation of Digital Watermarking System for Real Time Captured Image Transmitting
 
13:51
The art and science of writing hidden message in to the digital media in such a way that no one apart from intended recipient knows existence of message called as steganography. The detection of hidden message by steganographically encoded packets called as steganalysis. In this paper a novel Steganographic technique using DWT (Discrete Wavelet Transform) and LSB (Least Significant bit) algorithm for transmitting captured images is proposed. LSB will used to hide data in least significant bit of pixel of an Image. The hardware implementation of the proposed method uses XPS & VB. Here MATLAB is used to convert the image in to the pixel format file. In XPS we select the required hardware and software component. Then by adding the source file and header file created in MATLAB & converted into bit streams and downloaded in to FPGA to get video frame.

IMPROVED WATERMARKING SCHEME USING DECIMAL SEQUENCES.wmv
 
06:22
Cryptography and steganography (covert writing) have been used to add secrecy to communication all though history. Early methods of hiding information include invisible writing using invisible ink, writing text on wax-covered tablets and using null ciphers. Null ciphers were developed during the World War II, in which a secret was camouflaged in an innocent sounding message. As technology improved and security became an important factor, other methods of hiding information were developed. Microdot technology was invented in 1941.Developments in this technology have advanced and today information is being hidden on strands of DNA using genomic technology. With the growth of the internet, steganography has found new applications. Since steganography is relatively insecure to hide information, watermarking which is a more robust method of hiding information came into existence. The growth in the distribution of media files over the internet has caused serious concerns regarding piracy and unauthorized distribution. The music industry claims annual multibillion-dollar loss in its revenues due to piracy, this poses a challenge to the cryptographers to improve on the existing copyright protection schemes and devise more robust and secure technologies. Digital watermarking is also used for authentication. In watermarking information (watermark) is hidden in the digital file; therefore it can be implemented in digital rights management (DRM), so that the digital media files are distributed only to those who are authorized to receive it. Traditional schemes of data protection such as scrambling and encryption are not feasible for multimedia digital files because the content must be played back in its original format, posing a threat of re-recording and re-distribution. Watermarking provides a solution to this, since the authenticity of the digital file may be recovered by detecting the watermark at the player (receiver). The existence of this watermark within the multimedia files goes unnoticed except when passed though an appropriate detector. Common types of signals to be watermarked are still images, audio, and digital video.

Digital watermarking
 
12:56
A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal; the hidden information should, but does not need to contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Like traditional watermarks, digital watermarks are only perceptible under certain conditions, i.e. after using some algorithm, and imperceptible anytime else. If a digital watermark distorts the carrier signal in a way that it becomes perceivable, it is of no use. Traditional Watermarks may be applied to visible media (like images or video), whereas in digital watermarking, the signal may be audio, pictures, video, texts or 3D models. A signal may carry several different watermarks at the same time. Unlike metadata that is added to the carrier signal, a digital watermark does not change the size of the carrier signal. The needed properties of a digital watermark depend on the use case in which it is applied. For marking media files with copyright information, a digital watermark has to be rather robust against modifications that can be applied to the carrier signal. Instead, if integrity has to be ensured, a fragile watermark would be applied. This video is targeted to blind users.

1999-09-10 CERIAS - Image and Video Watermarking: An Overview
 
01:06:30
Recorded: 09/10/1999 CERIAS Security Seminar at Purdue University Image and Video Watermarking: An Overview Edward J. Delp, Video and Image Processing Laboratory (VIPER), Purdue School of Electrical and Computer Engineering In the past several years there has been an explosive growth in digital imaging technology and applications. Digital images and video are now widely distributed on the Internet and via CD-ROM. One problem with a digital image is that an unlimited number of copies of an "original" can be easily distributed and/or forged. This presents problems if the image is copyrighted. The protection and enforcement of intellectual property rights has become an important issue in the "digital world." Many approaches are available for protecting digital images and video; traditional methods include encryption, authentication and time stamping. In this talk we describe algorithms for image authentication and forgery prevention known as digital watermarking. A digital watermark is a signal that is embedded in a digital image or video sequence that allows one to establish ownership, identify a buyer or provide some additional information about the digital content. In this talk we will review the current state of watermarking and describe some of the open research problems. Edward J. Delp was born in Cincinnati, Ohio. He received the B.S.E.E.

vel tech high tech Advance Encryption Standard in Digital Photography using Watermarking Techniques
 
06:41
In the past few years, semi-fragile watermarking techniques have become increasingly. Important to secure and verify the multimedia content and also to localize the tampered areas, while tolerating some non-malicious manipulations or attacks. In digital photography, watermarking schemes are very important for copyright protection purposes. In this paper, a multimedia authentication and restoration scheme is proposed with the security of AES-128 ciphered watermarking and correlated watermarking. An encrypted or ciphered image embedding is done by modified version of Closest Point Transform in a digital photograph. We performed several security attack e.g. noise attack, compression attack and cropping attack on multiple watermarked photographs and evaluated the proposed watermarking technique to examine the system robustness.

Robust Digital Audio Watermarking using MATLAB (Hiding Watermark/Logo into Audio)
 
05:15
This is Matlab Project/Thesis Work on "Digital Audio Watermarking".Watermarking is a technique used to hide data or identifying information within digital multimedia or for copyright purpose. In this work, we will hide a Watermark Image (Logo of any company) into a Digital Audio (i.e., Original Audio Sample). To improve the security and performance, an additional Private Key/Password would also be used in Arnold Transformation of Watermark Image for scrambling purpose. The same Private Key/Password would be used at the time of Decoding/Extracting the Watermark from Watermarked Audio.

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...

It is sometimes necessary to watermark these compressed encrypted media items in the compressed-encrypted domain itself for tamper detection or ownership declaration or copyright management purposes. It is a challenge to watermark these compressed encrypted streams as the compression process would have packed the information of raw media into a low number of bits and encryption would have randomized the compressed bit stream. Attempting to watermark such a randomized bit stream can cause a dramatic degradation of the media quality. Thus it is necessary to choose an encryption scheme that is both secure and will allow watermarking in a predictable manner in the compressed encrypted domain. In this paper, we propose a robust watermarking algorithm to watermark JPEG2000 compressed and encrypted images. The encryption algorithm we propose to use is a stream cipher. While the proposed technique embeds watermark in the compressed-encrypted domain, the extraction ofwatermark can be done in the decrypted domain. We investigate in detail the embedding capacity, robustness, perceptual quality and security of the proposed algorithm, using these watermarking schemes: Spread Spectrum (SS), Scalar Costa Scheme Quantization IndexModulation (SCS-QIM), and Rational Dither Modulation (RDM).

Steganograhy [Please read description]
 
04:29
Sorry, if you did not understand things about what I talked in video. I made it in a hotchpotch. Well, here are the thingies about what I wanted to discuss in the video. What is Steganography? Steganography is a means of obscuring data where secret messages are hidden inside computer files such as images, sound files, videos and even executable files so that, no one except the sender and the receiver will suspect the existence of stealth information in it. Steganography may also involve the usage of cryptography where the message is first encrypted before it is concealed in another file. Generally, the messages appear to be something else such as an image, sound or video so that the transfer of secret data remains unsuspected. The main advantage of steganography over other methods such as cryptography is that, it will not arose suspicion even if the files fall in the hands of a third party. Unlike cryptographic messages, stegnographic messages will no way attract the attention of a third party by themselves. Thus stegnanography has an upper hand over cryptography as it involves both encryption and obscurity. What are the Applications of Steganography? Steganography is mainly used to obscure confidential information/data during storage or transmission. For example, one can hide a secret message in an audio file and send this to another party via email instead of sending the message in the textual format. The receiver on the other end will decrypt the hidden message using the private decryption key. In a worst case scenario, even if a third party does manage to gain access to the email, all he can find is the audio file and not the hidden data inside it. Other usage of steganography include digital watermarking of images for reasons such as copyright protection. Even though steganography has many useful applications, some may use this technique for illegitimate purposes such as hiding a pornographic content in other large files. Rumors about terrorists using steganography for hiding and communicating their secret information and instructions are also reported. An article claiming that, al-Queda had used steganography to encode messages in images and transported them via e-mails, was reported by New York Times, in October 2001. How do Steganography Tools Work? Stegnography tools implement intelligent algorithms to carefully embed the encrypted text messages or data inside other larger files such as an image, audio, video or an executable file. Some tools will embed the encrypted data at the end of another file so that there will be enough room for storing larger data. There are many steganography tools available online but only a few are able to work flawlessly. I did not find any tool that worked perfectly on both small and large data. However, I have managed to develop my own tool that can work perfectly on all types of files and all size of data. The tool is called “Stego Magic“. You can download it from the following link. Here is the link as discussed in the video :- http://www.gohacking.com/downloads/resources/StegoMagic.zip The zip file contains two versions of Stego Magic: One for encrypting the text messages and the other for encrypting binary files. StegoMagic_TXT can be used to hide text messages in other files such as an image or a sound file. StegoMagic_BIN can be used to hide one binary file in another such as an executable file inside an image or an image inside a video file. With Stego Magic, there is no limitation on the size and type of the file that you are intending to hide. For example, you can hide a video of size 1 GB in an image of size 1 MB or hide an executable file inside a WORD document. The tool is pretty straightforward to use and requires no special understanding of the concept. At the end of the encryption process, a secret decryption key will be generated and the same is required during the decryption process. How to Use Stego Magic? Suppose you want to hide a text message inside a JPG file: 1. Place the JPG and the text file (.txt) in the same folder as that of StegoMagic_TXT.exe 2. Run StegoMagic_TXT.exe and follow the screen instructions to embed the text message inside the JPG image. Also, as discussed in the video, in Windows 7 and Vista you need to run it as administrator. 3. Note down the secret decryption key. Now you can send this image to your friend via email. To decrypt the hidden message, your friend should load this JPG file onto the Stego Magic tool and use the secret decryption key. I hope you’ve now understood what is steganography and how to use it to hide your secret data. For queries and feedback, please pass your comments.

Reversible Watermarking Based on Invariant Image Classification and Dynamic Histogram Shifting

To get this project in ONLINE or through TRAINING Sessions, Contact: JP INFOTECH, 45, KAMARAJ SALAI, THATTANCHAVADY, PUDUCHERRY-9 Landmark: Opposite to Thattanchavady Industrial Estate, Next to VVP Nagar Arch. Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Reversible Watermarking Based on Invariant Image Classification and Dynamic Histogram Shifting In this paper, we propose a new reversible watermarking scheme. One first contribution is a histogram shifting modulation which adaptively takes care of the local specificities of the image content. By applying it to the image prediction-errors and by considering their immediate neighborhood, the scheme we propose inserts data in textured areas where other methods fail to do so. Furthermore, our scheme makes use of a classification process for identifying parts of the image that can be watermarked with the most suited reversible modulation. This classification is based on a reference image derived from the image itself, a prediction of it, which has the property of being invariant to the watermark insertion. In that way, the watermark embedder and extractor remain synchronized for message extraction and image reconstruction. The experiments conducted so far, on some natural images and on medical images from different modalities, show that for capacities smaller than 0.4 bpp, our method can insert more data with lower distortion than any existing schemes. For the same capacity, we achieve a peak signal-to-noise ratio (PSNR) of about 1--2 dB greater than with the scheme of Hwang et al., the most efficient approach actually.
