Digital Image Steganography

         Digital image steganography sounds really cool to me. Personally, I think it is like how you can write with invisible ink to send a message to someone else. In reality, digital image steganograpghy is in a way invisible ink but for messeges but digitally. Before we get into the big details about digital steganography, a little but about regular steganography. Something interesting I found while researching what digital steganography is, would be how steganography has changed through the ages. In an article it mentioned how messeges were tattooed on shaved heads and then the hair would grow back so it would be hidden. I found this fasinating even if I don't like tattoos, but because this is still having hidden messages.

        This is exactly what digital image steganograpghy is. A more modern version of what it used to be. All it is, is hidden messages in images, HTML, audio and video files. Usually, image steganograpghy is only hidden messages in images. It was said that some terrorist groups used a different steganography, digital stenganography. The way I see digital image steganography is that it is made up of millions of different colors. When you make an image on the computer, each color represents a code of numbers. It would make sense if you are trying to hide a messege within an image, you would have a code with what the numbers mean. That would make up the image. I hope you enjoyed this fascinating post about digital image steganograpghy and keep on reading this blog!
