When you fill a PDF form and save, informations can be embedded in the PDF. However, some PDF viewers don't show the filled values, which can lead to an accidental leak of information, even after double-checking!

Here is a hand-written PoC https://corkami.googlecode.com/svn-history/r1936/trunk/src/pdf/PDF_form_leak.pdf

Technically speaking, the filled values are the /V string fields in the /Annot objects.
