20070180502, "Rights-Context Elevator," assigned to Microsoft.
System(s), techniques, and/or method(s) ("tools") are described that enable a user to elevate his or her rights. The tools may do so by switching a user to an account having higher rights or a different, higher-rights context of a same account. The tools may elevate a user's rights after a user enters a secure access sequence, such as Control+Alt+Delete, clicks on a button, or enters credentials. The tools may also enable a user to identify tasks that need higher rights to be performed by visually correlating graphic indicia with these tasks.
20070174197, "Method to protect digital data using the open mobile alliance digital rights management standard," assigned to Mobile Action Technology Inc. (TW).
A method to protect digital rights using an OMA DRM standard has acts of generating an encryption key and an ID unique to a user and a decryption key, encrypting the digital content using the encryption key into an encrypted object, packaging the ID and the decryption key into a rights object, delivering the ID and the encrypted object to the user's mobile device, delivering the rights object to the user's mobile device, verifying ID delivered with the encrypted object and ID in the rights object and decrypting the encrypted object. The method replaces assigning a conventional identifier to each digitized content with assigning each user a unique ID. For either the rental service or the purchase service all downloaded content in the user's mobile device is accessible based on the same rights object to improve unreasonably receiving so many rights objects for each downloaded digital content.
