Using Facebook for Image Steganography
This addresses a practical challenge for users seeking covert communication on social media, though it is incremental as it builds on existing steganography techniques.
The paper tackled the problem of Facebook's image compression disrupting steganography by developing a method to minimize this disruption, enabling JPEG images to serve as effective carriers for hidden information on the platform.
Because Facebook is available on hundreds of millions of desktop and mobile computing platforms around the world and because it is available on many different kinds of platforms (from desktops and laptops running Windows, Unix, or OS X to hand held devices running iOS, Android, or Windows Phone), it would seem to be the perfect place to conduct steganography. On Facebook, information hidden in image files will be further obscured within the millions of pictures and other images posted and transmitted daily. Facebook is known to alter and compress uploaded images so they use minimum space and bandwidth when displayed on Facebook pages. The compression process generally disrupts attempts to use Facebook for image steganography. This paper explores a method to minimize the disruption so JPEG images can be used as steganography carriers on Facebook.
