Block the "copy" functionality of a pdf with itextsharp on vb.net

0

I have a function that receives a pdf uploaded by an input and saves it in a selected path, the idea is that between the process that loads the pdf and saves it in another directory block the option to copy the pdf with itextsharp

I would like to know if there is a functionality that does that
