Xerox copier flaw changes numbers in photocopied docs
A German PhD student has found a flaw in some Xerox photocopiers that fudges the numbers on some copies thanks to poor data compression.
Last Wednesday, computer science student David Kriesel was copying some building plans on a Xerox WorkCentre, and when checking the copies he found some of the dimensions of the plans had been altered, with three room measurements out of sync with the original documents. In particular, the number six was being changed to an eight.
