I love the idea that I can sell my web browser's bookmarks and history. How I wish I had not deleted my browser history.
But I guess Attention Date = Identity is too far-fetched. It could be more like a profile or persona but does that uniquely identifies me? Well guess that goes to what do you mean by identifies. If the identification is a "checksum" of my data then yes but other than that it resembles more like the way a corporation would like to see me i.e. a classification system.
