Steganography Explanation and Code Examples (Least Significant Bit)

An explanation of how steganography works, and a demonstration of the Least Significant Bit Replacement algorithm in python for: - Embedding a message into a digital image - Extracting a message from a digital image (reversing the encoding process) Using the data concealment method above, one can hide messages (secrets) in images, and use those cover image to communicate in plain sight. One can not just embed text in images, but embed maps, images, audio, video, executable code, snooping / keystroke loggers, just about anything that one can represent in binary (which is everything?). These make digital image steganography extremely stealthy and versatile. Makes you wonder just how prevalent is this form of cybersecurity risk; maybe in a future video we can explore counter-measures and its impact on the current generation of the web!
