Chunk 3, question 3, 5th response

From what I could find, steganography is a way of hiding data within another piece of data. Some people may confuse steganography with cryptography, but in reality these two methods are very different. While cryptography is used to make something unreadable to a third party, steganography’s goal is to hide data from a third party completely, much more private that cryptography. The one thing that is most scary about steganography than anything else is the fact that an ordinary person is not supposed to know that it exists, so someone could be planning the next major terrorist attack right in front of our eyes and we would have no idea or defense mechanism against it.

In the book, Chumbo describes his way of using steganography. He says that using iPods to hide information and transfer potentially harmful information is very useful because a person is a lot less likely to check an iPod for steganography that they are to check a laptop or something else much bigger than an iPod. I was very confused on how he might achieve this because I am not 100% sure what Chumbo says he puts on these iPods. Does he just put songs in a particular order that signify a message, or does he record other things and just put it on an iPod? I believe that Chumbo is using steganography to tell people, or at least lead people on, about where the containers are and what is inside of them, but I don’t think he tells anyone the truth, and in reality, he is the only one who knows about the containers.
Steganography could have very easily been used in the planning of the 9/11 attacks, and since this is a post 9/11 book, I find it very hard to believe that a concept like steganography finding its way into Gibson’s book is a coincidence.
