Would you notice?

From Bloomberg Businessweek

Xerox is now saying that some of its scanners can alter numbers in documents, even at the highest resolution setting. It blames a software bug for which it does not yet have a fix. “We continue to work tirelessly and diligently to develop a software patch to address the problem,” the company said in an Aug. 11 statement.

The problem came to light when German computer scientist David Kriesel scanned a construction plan on a Xerox machine and noticed that it changed numbers on some of the room measurements.

Would you notice such a thing? I'm not sure I would.

Seems appropriate that it took a German to notice it.

And are people aware that modern photocopiers keep a copy of everything on their hard drive, so that there are date security issues?

Sackers - I wondered if the copiers were also doing some character recognition too. That would allow the hard drive to be searched by content.
