• Images can be digitally altered to change the facts.
• Sometimes the process used to hide information can be undone.
• Steganography is used to hide messages inside of images.

If any image on the internet could hide secret messages, how can governments or other agencies find these message?

Some companies, like ebay, process images when uploaded to remove possible hidden messages. Should all image hosting sites be required to modify images to remove messages?

Finally, can you think of reasons we would not want possible steganography to be used? In other words, is there a good use of steganography or is it all negative?
