Data Hiding using Image Steganography and LSB Substitution.

      Аннотация: Steganography is the practice of hiding private or sensitive information within something that appears to be nothing out to 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 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. What Steganography essentially does is exploit human perception, human senses are not trained to look for files that have information inside of them, although this software is available that can do what is called Steganography. The most common use of Steganography is to hide a file inside another file. One of the reasons that intruders can be successful is the most of the information they acquire from a system is in a form that they can read and comprehend.
