Hello, I'm planning on selling a product which contains an Ebook and some instructions videos. The estimated file size will be around 1-2 GB so I need to upload to my own server/website and so I will sell this through my own website where people have to sign up and pay in order to get an url (which links to the file) emailed to them. Regarding to this I had a question: Is it possible when a buyer of my products transfers his money to me(ie. paypal) gets an unique url to download and access the file through an email I send him? Or maybe even an unique url/password combination? Are there any services or programs online that can offer me this ability to 'secure' my files and prevent them more or less from illegal spreading and copying? I have heard some things about this, but they are usually paid services. Aren't there any cheap ways to do this? Thanks!
Could you please give me some more information on that? I'm really looking for a high end security system so that it is almost impossible to leak my product... Thanks !
