Abstract
Embodiments provide a system for content distribution and protection. The system first receives an order from a user for a protected document. In response to a successful user authentication, the system generates an access code for the user to access the protected document. In response to a received user reading request, the system validates the access code for a reading session. The system then transfers a set of URLs for accessing a set of pages and associated metadata in the protected document to the user. The set of URLs are valid for a period of time. Responsive to a request for reading a next set of pages, the system again validates the access code for the session and transfers another set of URLs for accessing the next set of pages. The system also logs user activities related to the protected document.
