Abstract:

A digital rights management system for wireless platforms. The system includes client software running on the wireless platform for publishing and/or viewing protected content. Enterprise server code is executed on a first server platform for sending and receiving protected content. An extension on the enterprise server code is included for detecting the presence of protected content, storing any such protected content in memory and substituting new content for the protected content for viewing on the wireless platform. A digital rights management server provides licenses for viewing the protected content on the wireless platform. A license proxy server is coupled to the wireless platform and the digital rights management server and communicates data therebetween. In the illustrative embodiment, the protected content is digitally rights managed email message. In more specific embodiments, a rights managed secure viewer and a secure publisher run on the wireless platform. The new content is a modified email message with the same addressee, addressor or subject of the protected content along with instructions relating to the downloading of the protected content. Code is provided on the license proxy server for retrieving a license with respect to the protected content on the execution of the instructions by a user via the wireless platform. The license is retrieved from the digital rights management server by the license proxy server. The license proxy server uses the license to decrypt the protected content using the license. The license proxy server then re-encrypts the message using an encryption algorithm that may be decrypted with a corresponding decryption algorithm stored on a rolling temporary lockbox and sends the re-encrypted message to the secure viewer. The rolling temporary lockbox is one of plural rolling temporary lockboxes. The secure viewer receives and decrypts the re-encrypted message from the lockbox and allows the user to publish protected content.

Abstract:

A digital rights management system and method. The inventive system includes a client for publishing and/or viewing protected content; a DRM server for providing licenses for viewing the protected content; and an inventive license proxy server coupled between the client and the server. The license proxy server includes a digital rights management lockbox and plural digital rights management client certificates. The license proxy server is disposed on an operationally independent platform relative to the client or the DRM server and thereby extends a DRM vendor's rights management capabilities to other platforms.
