It should not include exact historic numbers either, because they, too, would allow to puzzle the numbers together and allow to again build a history of IP addresses for a given user. Similarly, the exact time of the previous submission would allow to piece submissions together and must not be submitted, but rather only the day (2011-02-12, not minutes or seconds, or even milliseconds). It must be impossible to match 2 submissions together, even when considering several parameters as a collection, see http://panopticlick.eff.org/ . | |||
