This video aims to connect many topics in computer science to reach the writing of an application that can do something useful in actual life. The student will get to know the concept of ciphering and hiding (Steganography in bitmap files), will have a glance at the American Standard Code for Information Interchange table "ASCII", will understand the structure of bitmap (BMP), and learn how color is stored. Also students will learn how to do some byte and bit level operations, and how to manipulate binary files. They will then use Visual Basic, or another programming language, to write a Windows application that ciphers and hides a computer file inside a digital picture or a photo -- with the look and feel of the image the same and no change whatsoever to its size. Prerequisites: It is recommended that students have previous knowledge of: Binary Systems; Computer storage unit "Byte", and its multiples: Kilo, Mega and Giga; Hexadecimal Editor; Programming basics and manipulating binary files.
