Another limitation of blacked-out documents

"The researchers showed their software at the conference, called Eurocrypt, by analyzing a presidential briefing memorandum released in April to the commission investigating the Sept. 11 attacks. After analyzing the document, they said they had high confidence the word 'Egyptian' had been blacked out... [The technique] involves first using a program to realign the document, which had been placed on a copying machine at a slight angle... Next, they found the number of pixels that had been blacked out in the sentence... They then used a computer to determine the pixel length of words in the dictionary when written in the Arial font. The program rejected all of the words that were not within three pixels of the length of the word that was probably under the blacked-out area in the document."

Sounds like the software is making nothing more than an educated guess.
