Images as passwords
While watching a Bank of America (bastiges) ad today, I realized that passwords could potentially be greatly improved by utilizing specific images. Instead of the standard text-only password, why not use an image? Ok, sounds goofy and inconvenient, but hear me out. All you'd need is some AJAX, an image repository (say flickr) and a visual memory. I think it could be done pretty well. The beauty of using flickr is the amazing repository of images. You could basically pick any one of them. The problem is the potential for images to be relabeled, deleted or moved off into that flickr limbo that some images go to.
Something to think about (and write up).
