Hide Your Data In Image

There are many encrypting techniques which are used. Encryption of files having data is used to get it transmitted through internet safely to the recipient. When a file is transmitted via mail there is a great possibility of that file to get hacked. Unauthorized access of any file is prevented through the process called encryption.

Well, I have a great way to encrypt any file or multiple file within an image. Does it not sound amazing? To me it did. when I came to know this method I just spun off from my chair. I am sure that you all gonna like it.

To get this encryption done we need to use DOS command prompt using /b to covert any type of file to an image. The file may have extensions like file1.txt, file2.mp3 and file3.wav etc. So we must look at the process instead of narrating the Jargon.

suppose you want to encrypt the files: file1.txt, file2.mp3 and file3.swf . Put all this files in a folder namely “sample”. We now need a compressing s/w like Winrar.

Thereafter, all we need is to compress the files and name it as “Test” (say). Put this folder in any drive. suppose it is kept in drive D:/. Now its required to open the DOS command prompt. ( type cmd in run dialogue box ). The default directory must be changed to the directory which is containing the stuffs to be encrypted. Here, it’s the folder “sample” in drive D:/.

The DOS command would look like D:\Sample>

Now, use a image say “image1.jpg” to hide the data inside it. This image must be kept in the drive which contain the folder “sample”.

Now there is a small operation which will encrypt your data by hiding it in the image “image1.jpg” type the following in DOS prompt ( the blue part)

D:\sample>copy /b Test.rar + image1.jpg encrypted.jpg

Single.rar is our combined files in rar format and image1.jpg is the image file where we are going to hide the sample1.rar file. Test.jpg (you can use any name of your choice) is the resultant image file that contains the rar file.

The switch ‘/b’ indicates that we are performing the binary copy.

Now, everything is done. Using this method we can hide virtually any file type like rar, swf, mp3, txt, exe etc within an image. The image file may be a jpg, png, bmp or gif.

Advantages:

- Supports hiding any file type within an image.
- No additional tool/software is required.
- Less time and resource consuming.
- You can hide an exe file into jpg and send it through e-mail .

Disadvantages:

- It is not a good method for encrypting any important data.
- The resultant image does not open when a file of higher size is hidden inside it.
