Question:

I. Explain what steganography is and how it applies to cryptography and encryption standards. Stress that this is used as a data hiding method and involves embedding information within files.
II. Emphasize that the word “steganography” is derived from the Greek words,“steganos,” meaning “covered” and,“graphein,” meaning “to write.”
III. Assess and propose the most popular modern version of steganography, which involves hiding information within files that appear to contain digital pictures or other images.
IV. State that most computer graphics standards use a combination of three-color values (red, blue, and green (RGB)) to represent a picture element, or pixel. Each one of the colors has an 8-bit binary code. For example, 00000000 is no red and 11111111 is all red.
V. Provide examples and justifications of applications that can hide messages. This includes .bmp, .wav, .mp3, and .au files. Unused storage on CDs and DVDs are alternate examples to share with students.
