New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents concern aspects of digital rights management.

Assigned to Samsung, the second patent addresses techniques for controlling access between home device and external server in home network system.
9,479,328, "Secure key provisioning," assigned to Amazon.
Some examples include provisioning secret material onto an electronic device. For instance, an electronic device may be provided with a provisioning key that can be used for provisioning other secret material on the electronic device. The provisioning key may be encrypted at a secure location using an on-chip key that is also sent to a processor manufacturer. The encrypted provisioning key may subsequently be decrypted by an electronic device having a processor installed that includes the on-chip key. The provisioning key is saved to the device and may then be used for securely provisioning other secret material onto the electronic device, such as one or more keys, one or more digital certificates, or other digital rights management information. Accordingly, the provisioning key provides the device manufacture with the ability to securely install secret material to the electronic device using a key that is never shared outside of a secure environment.
9,479,504, "Method and apparatus for controlling access between home device and external server in home network system," assigned to Samsung (KR).
A method for controlling access between home devices and servers in a home network system is provided. The method includes determining whether first access of the home devices to each of the servers and second access of the servers to each of the home devices is restricted, and controlling the first access and second access based on respective access rights established according to the determination.
