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 graphei (γραφή) 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, messages will appear to be something else: images, articles, shopping lists, or some other cover text and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.
The advantage of steganography over cryptography alone is that messages do not attract attention to themselves. Plainly visible encrypted messages—no matter how unbreakable—will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal.[1] Therefore, whereas cryptography protects the contents of a message, steganography can be said to protect both messages and communicating parties.
This is the manual way here, their are many tools available on internet also. You will only need to install winrar on your computer for this.
1. Make ZIP or RAR archive of all your files you want to hide and copy it to c:\data\
2. Copy any jpeg picture to folder “c:\data”.
3. Open command prompt and type the following command.
cd C:\data // this make c:\data to your working directory
then give this command as it is.
copy /b logo.jpg + secret.zip output.jpg
Here logo.jpg is the picture you want to show, secret.zip is the file to be hidden, and output.jpg is the file which contains both.
Now,after you have done this, you will see a file output.jpg in c:\data.
Open it (double click) and it will show the picture you wanted to show. Now try opening the same file with WINRAR, it will show the hidden archive.
There are so many Stegnography tools available on Softpedia here.
