Security with urls

[wallstreetoasis_com]

Hi,



I am trying to sell some ebooks to universities and have a few questions about security. Basically, the school pays a license so that the schools students can access the ebooks for free.



We can make it so the link to a free checkout (through the e-junkie cart) is available on their intranet.



My concern is that once this link gets out students from other non-paying schools will get access to it and use it to get free copies.



I think the issue would be resolved if we could disguise the url to the free checkout so that it could not be sent to outsiders.



Is there a solution to this? Please help -- we are trying to set this up for our first university as soon as possible.



Regards,

Patrick

Hello,



I responded to your e-mail but I will put a response here as well.



You can put a limit of number download attempts or time frame on the file so after the free checkout the student only gets say two download attempts or 2 hours to download the file. This will likely be the easiest way.



Another option is to send the student a code. You can then put in their University e-mail address for them to login to a site with the code they were given plus their University e-mail address. However they can give this information to friends at other Universities. You will need to keep track of who is logging in to the site and downloading the file so you can then remove their e-mail address and the code from the list of approved logins.
