Does TiVo know what you watch? David Martin, Assistant Professor of Computer Science at the University of Denver, has written a paper asserting that TiVo “gathers enough information to track individual users’ home viewing habits while apparently promising not to do so;�could identify the personal viewing habits of subscribers at will; and�has a much more explicit privacy policy disclosure on its Web site than in the printed material that accompanies the purchase of the product.” Link
