steganography

                    What Is Steganography?

Steganography is the practice of hiding private or sensitive information within something that

appears to be nothing out of the usual.

Steganography is often confused with cryptology because the two are similar in the way that they both are used to protect important information.

The difference between the two is that Steganography involves hiding information so it appears

that no information is hidden at all.

If a person or persons views the object that the information is hidden inside of he or she will have no idea that there is any hidden information, therefore the person will not attempt to decrypt the

information.

Steganography comes from the Greek words Steganós (Covered) and Graptos (Writing).

Steganography in the modern day sense of the word usually refers to information or a file that has been concealed inside a digital Picture, Video or Audio file.

What Steganography essentially does is exploit human perception, human senses are not trained to look for files that have information hidden inside of them, although there are programs

available that can do what is called Steganalysis (Detecting use of Steganography.)

The most common use of Steganography is to hide a file inside another file.

When information or a file is hidden inside a carrier file, the data is usually encrypted with a

password.
