Is this another reason not to post Word docs online?

Search Engine Watch featured an article yesterday about hidden data and search engines.

From the article:

Simon Byers, an AT&T security researcher, used a search engine to find more than 100,000 Microsoft Word files on the web, including business documents and resumes. He then used the free software tools "antiword" and "catdoc" to convert them to plain text.

Byers found deleted text and information including names, email headers, network paths and text from related documents — potentially compromising information that people publishing the documents to the web likely did not realize was included.

I mean, yikes! Who knew that what you deleted isn’t necessarily deleted online?

Here’s another article on the topic from New Scientist.
