Apparently assigned to Intel, the second application discloses techniques for connecting mobile devices, internet-connected vehicles, and cloud services.
20120260094, "Digital rights managmenet using attribute-based encryption," assigned to Koninklijke Philips Electronics N.V. (NL).
A data provider (1) for use in a digital rights management system comprises a data protector (2) for protecting data (20), using attribute-based encryption, in dependence on an access policy over a plurality of attributes. A license issuer (3) issues a license (17) comprising a representation of a set of usage rights (18), wherein the set of usage rights (18) is associated (19) with the data (20), for granting the usage rights (18) in respect of the data (20) to a plurality of entities (10) having attributes satisfying the access policy. A data receiver (10) comprises a data access subsystem (11) for accessing data, using attribute-based decryption, in dependence on a decryption key (16) associated with a set of attributes. The data receiver (10) further comprises a usage constraining subsystem (12) for constraining the access to the data (20), based on a license (17) comprising a representation of a set of usage rights (18) associated (19) with the data.
20120254960, "Connecting mobile devices, internet-connected vehicles, and cloud services," apparently to Intel.
A three-way trust relationship is established between a mobile device, Internet-connected vehicle system, and a cloud-based service. Access rights are granted to the mobile device from the vehicle system, such that the mobile device can securely connect to, and obtain status information and/or control the Internet-connected vehicle system, through the cloud-based service.
