Who Are You? Non? Anon?

"The Caterpillar and Alice looked at each other for some time in silence: At last the Caterpillar took the hookah out of its mouth and addressed her in a languid, sleepy voice. "Who are YOU?" said the Caterpillar. This was not an encouraging opening for a conversation." -- "Alice's Adventures in Wonderland" by Lewis Carroll

Last week I began a discussion on privacy and distinguished factual privacy ("static" facts about you like the color of your hair) from "lifestream" privacy (information about what you do, where you go and who you communicate with). Before I follow up, as threatened, by discussing how businesses abuse their knowledge of your lifestream data, this week we need expand on our discussion of privacy by delving into the issue of identity.
