Mementos as Document Retrieval Keys
Dekaner writes "The BBC is running a story that BT has demonstrated a scanner that can be used to retrieve digital documents by associating them with a physical object. When the digital files are stored on the server, they are associated with a scanned image of the object, for example a seashell. Later, when the user wants to retrieve the files, the memento is again placed on the scanner. The resulting image is used as the retrieval key."
This situation seems much the same. Most of the files I save on a computer are NOT associated with some object I have lying around the house. For example, everytime I write a letter to Mom, I'm suppose to scan her picture? Why not just save it in a folder called, "Letters to Mom." Its easier, quicker, and I don't have to find Mom's picture. Similarly at work, most of my files are associated with some email telling me to do work on some project. Do I scan the email? Seems kind of pointless.
In my view, like metadata, this suggestion adds steps that the vast majority of users won't do.
But that's NOT why I associate this with Johnny Mneumonic. I associate it because in the beginning of the movie, they're going to store 80 gigs of information (about as much as I have in /usr/home/) in Just Johnny's head. They use three random images from the television to associate with and encrypt the information. These images are then faxed to the recipient. Obviously the bits aren't being used because they would change in faxing. A more associative method is used, kind of like a human memory. I think that with time, more technologies like this will be used as our computational needs advance; That is, unless these multibillion dollar corporations have their way and our computers become merely vessels for receiving garbage information (valuable intellectual property) like the stupid movies and music being made nowadays, while "real" computers will be labeled as "professional equipment" and will cost five hundred times as much as they should so that only the corporations can afford them to keep us under control.
In the world of the future, it will be corporations, not governments, that will oppress the people. The governments will only serve as a tool to those corporations. Capitalism is fine; I just think that one change needs to be made: The individuals should have a much louder "voice" in government issues than corporations. In fact, the "voice" of any party should be inversely proportional to its size and power. The RIAA should not have enough voice to mail a letter to a senator, let alone do the evils that they are doing.
Using images of physical tokens to access documents is a really old idea. Of course, that won't stop BT from filing a patent.
This is a sure fire recipe for data loss of critical data. All the server backups you can make would become worthless if the seashell/encryption key falls into the hands of a three year old with crayon or is lost/ruined in any other way.
It's a nice novelty for encrypting your digital little black book, but it's not going to be useful at all for business databases.
