9,805,350, "System and method for providing access of digital contents to offline DRM users," assigned to Infosys Limited (IN).
The invention relates to a system and method providing access of one or more heterogeneous digital contents to at least one offline Digital Rights Management (DRM) user by a DRM server. This invention involves establishing the trust relationship among the DRM server, DRM client, user's machine and the end user by means of digital certificate. The server generates protected digital content by means of using a standard encryption algorithm. The invention further involves determining whether a license for accessing the protected file is requested by the legitimate user, and if so, generating a license consisting the user rights and the protected decryption key to be downloaded by legitimate user. The DRM client decrypts the protected file using a decryption key of the license, and renders the content to the end user by calling the appropriate and customized viewer during consumption.
9,807,443, "Systems and methods for providing storage of data on servers in an on-demand media delivery system," assigned to Rovi Guides, Inc.
A system and method may be provided that allows users to store, retrieve, and manipulate on-demand media content and data stored on a remote server network in an on-demand media delivery system. More particularly, the system may allow a user to access his or her on-demand media account from user equipment in different locations as long as the current user equipment can communicate with a remote server that stores user-specific information. The system upon user selection may freeze the delivery of on-demand media at a particular point and allow the user to resume the media at a later time from some other network location in system. Users may upload personal images or files to an on-demand delivery server for later retrieval and display. Users may be permitted to assign access rights to the uploaded files.
