Abstract
An E-DRM remote caching system enables a user without a client side E-DRM access component to view E-DRM governed content on a variety of client devices. The user transmits inaccessible E-DRM governed content to be viewed to a the remote caching system. The remote system receives the content, temporarily stores it in a cache, and determines whether the user has sufficient rights to view the content. If the user does have sufficient access rights, the remote system transforms the content into a secure, viewable format and securely transmits it to the user. The user can view the E-DRM governed content without an E-DRM client side access component. The E-DRM remote caching system can add a unique digital marker to received content. The marker can be subsequently used to identify the origin of compromised content.
