Inserting a hidden code in PDF metadata

[Stabes]

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,

Martin

Sure. Just add your custom metadata value and then apply a security policy that prevents editing the file.

It's not 100% secure, but it should work for most people.

Great. Thanks.
