ebook download security question
A friend of mine is planning on self-publishing a book, via a website as a downloadable pdf, and then through something like Lulu for people who want a nicely bound offering.
So, the question is Paypal. I've got as far as going through the documentation, seeing how you can set up a pay now button etc. Which then directs back to the website for downloading the file.
My question is this. How secure is that? Or rather, how secure is the page on which you can download it? What measures can I put in place to maximise security? I'm only asking because googling this just gives a list of commercial companies hell-bent on trying to sell you something.
Anyone able to shed some light on this?
