Xerox Photocopiers Randomly Alter Numbers, Says German Researcher

First time accepted submitter sal_park writes "According to a report from German computer scientist D. Kriesel, some Xerox WorkCentre copiers and scanners may alter numbers that appear in scanned documents. Having analyzed the output of two such devices, the Xerox WorkCentre 7535 and 7556, Kriesel found that "patches of the pixel data are randomly replaced in a very subtle and dangerous way": in particular, some numbers appearing in a document may be replaced by other numbers when it is scanned."

They are not their ancestors. Which should be pretty damn obvious to anyone with at least two brain cells to rub together.
