Here’s some Python code (it uses my mPDF module) to append a new PDF document to an existing PDF document to “hide” the original document. Recovering the original is trivial, you open the PDF document with a HEX-editor and delete the appended document (starting after the second %%EOF counting from the end of the file). This trick uses incremental updates.
