TSA now recording names of people who fly without ID

At Midway airport this past weekend, when I chose to fly without ID, the TSA agent took my boarding pass and wrote down the majority of information from the boarding pass (Name, flight into, destination, confirmation number) onto a form. I asked her what the form was, and if I could have a copy, and she basically indicated to me that it was not my business. (Note that no forms were filled out on my return trip through Philly.)

This brings up a number of rather important questions:
1. Is there a statute or rule that allows the TSA to routinely record traveler information, with or without an ID?
2. How long does the TSA store this information for, and what is it used for? Do travelers have a right to check the accuracy of the information, or to have it expunged?
3. Is this really a secret form that citizens are not allowed to have a copy of? If a traveler requests that information not be recorded will that traveler be denied passage?
