Hide Data in Image, Audio and Video Files: Steganography
Ever wondered to know how to hide secret data in image, audio and video files? Well, in this post I will take you through a concept called steganography using which, it is possible to hide your secret information in image files, songs or any other file of your choice. At the end of this post, you can also download free stegnographic tools and start hiding your data.
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.
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:
-
Place the JPG and the text file (.txt) in the same folder as that of StegoMagic_TXT.exe
-
Run StegoMagic_TXT.exe and follow the screen instructions to embed the text message inside the JPG image.Please note that if you’re using Windows 7/Vista, right-click the file and select “Run as Administrator”. Otherwise the tool may fail to work properly.
-
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.

Uniblue DriverScanner 2013 v4.0.9.10 Full
Device drivers are without doubt some of the most important programs running on your PC. If any of them have bugs then this can lead to all kinds of problems: poor performance, unexpected crashes, spontaneous reboots, lengthy shutdowns, and a whole lot more. It pays to keep your drivers up-to-date, then, and Uniblue DriverScanner 2011 can help you do this quickly and with the minimum of fuss.
To give your PC this valuable health check, just launch the program and click Start Scan. Uniblue DriverScanner 2011 will compile a list of your installed drivers and their version number, compare these with its own database of the latest versions, and let you know which drivers have updates available.
That's just the start, though. If the program has found updates then it'll download them all at a click (and in parallel, for the best performance). You'll be warned about drivers that may be risky to install, perhaps causing system instability. But if everything looks good then you can install each update in turn with another click.
Of course driver updates can sometimes cause problems, too - you might download a version that introduces a new bug, for instance. But Uniblue have thought of that, too. DriverScanner 2011 creates a restore point every time it installs a new driver, and so if you do experience any issues then they're easily fixed: just click the Manage tab, choose the appropriate Restore tab and your system will be returned to its previous state. Mark that driver as one to ignore and the program won't try to download it again, which means you'll be safe until a new, and hopefully fixed version appears.

Turn a USB Flash Drive into a Bootable Windows 7 Installer
Turn a USB Flash Drive into a Bootable Windows 7 Installer
Hi all users, many of you asked us about some idea on how to install Windows 7 OS from USB thub drive (Pen Drive) so we found this easiest way to do so is by using the tool Microsoft offers, cunningly named the Windows 7 USB/DVD Download Tool. To get started,download the software and install it.
Once it is installed, it should create an icon on your desktop, so double-click that to open. If you can't find it, use the search function in the Start Menu with a keyword like "USB." Launching it should give you the above screen, and step one is to find the Windows 7 .ISO file. The tool only accepts .ISO images, so we recommend that you convert yours if it's in a different DVD image format.

Launching it should give you the above screen, and step one is to find the Windows 7 .ISO file. The tool only accepts .ISO images, so we recommend that you convert yours if it's in a different DVD image format.
Step two is straightforward: simply choose USB device.
In step three, all you have to do is make sure that you are choosing the correct USB device. If you have other data on the device, move it to your hard drive, another USB device, or somewhere else before proceeding.
The tool will prompt you if it detects data on the device. Once your data is backed up elsewhere, click Erase USB Device.
You will get another prompt warning you that all the data will be wiped. Click Yes to continue.
The format will be very quick, while the copying of the files will take a little bit more time (about 10 to 15 minutes).
Once the process is complete, you should get the above confirmation message. At this point you can close the tool and use the USB drive to install Windows 7. Remember that you'll have to choose to boot from the USB drive. Before doing so, you may want to open up the USB drive and double click on setup.exe to see if everything looks okay.

Adobe dreamweaver 8 serial number
Macromedia® Dreamweaver 8 dominates the world of professional web authoring in much the same way that Photoshop dominates photo-editing. It has achieved this commanding position by combining a wysiwyg design environment with unbeatable hands-on coding power and by focusing throughout on workflow-based efficiency. It is these same three core areas - visual design, coding and productivity - that are targeted in this latest release. In terms of wysiwyg design power, Dreamweaver 8 now falls into line with GoLive by offering a zoom capability - ranging between 6% and 3600%! - and Fit All, Fit Width and Fit Selection commands. The importance of this is seriously overplayed as web design is always viewed at 100%, but it should help users working on high resolution screens and possibly when aligning objects. Much more practically useful for accurately positioning layouts is the new support for rulers and draggable guides complete with tooltips for providing feedback on position and distances between. You can control the display, locking and snap setting of guides and Dreamweaver 8 includes a limited selection of preset guides representing the safe visible area of browsers at various screen sizes. Other improvements to Dreamweaver's wysiwyg design power concentrate on enhanced support for CSS (Cascading Style Sheets), the layout and formatting mark-up language designed to work alongside HTML. In particular the core Design View has been updated to fully support advanced CSS techniques such as overflow handling, form elements and pseudo-elements. And to make life a little easier when working with CSS-positioned layouts, new visual aides are available to highlight CSS outlines, boxes and backgrounds while new tooltips provide greater feedback. Most impressive is Dreamweaver 8's new support for CSS media types. Using the new Rendering Toolbar you can now swap between seeing how a page will look onscreen, on a handheld, or in print.adobe dreamweaver 8 serial number here you can download in very easily..
