    Inserting a hidden code in PDF metadata

    Stabes Level 1

      Hello all,


      We are supplying one PDF file to various educational institutions, and we would like the PDF for each institution to have its own unique hidden code.

      I was wondering if it was possible to insert hidden metadata into a PDF eg. a ten digit number, which might be visible to the user, but cannot be changed.


      Many thanks,
