Viewing content under enterprise digital rights management without a client side access component

摘要

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.

主权项

1. A computer implemented method for enabling a user without a client side enterprise digital rights management (E-DRM) access component to view content under enterprise digital rights management, the method comprising the steps of:
receiving from a remotely located user device without a client side enterprise digital rights management access component, by a computer, encrypted content identified as governed by an enterprise digital rights management system; temporarily storing, by the computer, the identified content governed by the enterprise digital rights management system in a cache; determining from a predefined E-DRM privilege, by the computer, whether the user device has sufficient access rights to view the encrypted content without a client side enterprise digital rights management access component; determining whether the user device is located in a location that allows access rights to view the encrypted content without a client side enterprise digital rights management access component; responsive to determining that the user device has sufficient access rights to view the identified content governed by the enterprise digital rights management system and that the user device is located at location that allows access rights to view the identified content, transforming the identified content into a secure, viewable format, by the computer, wherein the user device has more than read-only rights relative to the identified content but is restricted to read-only rights responsive to viewing the identified content without a client side enterprise digital rights management access component; and securely transmitting the identified content back to the user device in the secure, viewable format to the user device, such that the user device can view the identified content governed by the enterprise digital rights management system without a client side enterprise digital rights management access component.
