I have access to some of Apple's secret documentation and they watermark your name and email address over all the PDFs. I often wondered if they do something like this as well, just in case.

Only using synonyms is pretty limited though. You could go much further:

1. In PDF documents use layouts that differ by only a couple of pixels. 2. Change the placement of figures. 3. Change brackets to dashes (like this) - or like this. 4. Add double spaces in places. 5. Adjust the hyphenation at the end of long lines. 6. Use unicode look-a-like characters. 7. Use different unicode variations of dashes and quotation marks.

If you only had a single document and wanted to leak it while being certain that your name wouldn't be leaked too, the only way I can see to do it would be to rewrite it in your own words.
