Autonomous-Mode Content Delivery and Key Management
First Claim
1. A system for providing an in-vehicle content-delivery service to a mobile consumer device, the system comprising:
- a data center including a license server configured to provide one or more keys, from a key-store, for decrypting encrypted content; and
a first content-delivery system (“
CDS”
) disposed at a first vehicle, the first CDS including;
one or more memory devices storing a content-distribution, from the data center, including;
a first set of keys from the key-store for decrypting a first collection of encrypted content; and
a first proxy license server configured to;
(i) determine whether license-data, stored at a memory of the first CDS, authorizes delivery, of first content-data from the first collection of encrypted content, responsive to a content-request received at the first CDS,the content-request received at the first CDS having been transmitted from a first mobile consumer device communicatively coupled to the first CDS,(ii) when the license-data authorizes delivery of the first content-data;
transmit, for reception by the first mobile consumer device, a key from the first set of keys for decrypting the first content-data.

Abstract
Multimedia content may be delivered to content consumer devices via a content-delivery network. Encrypted content and cryptography keys for decrypting the content may be distributed from a data center to various nodes of the content-delivery network, each node acting as a semi-independent content-delivery system. Each content-delivery system is capable of delivering received content to end-users and implementing a key-management scheme to facilitate secure content-delivery and usage tracking, even when the content-delivery system is disconnected from the data center. In other words, the disclosed systems and methods facilitate the operation of nodes which may operate in “autonomous mode” when disconnected from a larger content-delivery network, thus maintaining content-delivery capabilities despite having little if any connectivity to external networks.

12. A computer-implemented method for providing an in-vehicle content-delivery service to a mobile consumer device, the method comprising:
-
receiving, at a first content-delivery system (“
CDS”
) disposed at a first vehicle, a content-distribution including a first set of keys from a key-store managed by a license server, the first set of keys for decrypting a first collection of encrypted content;storing the content-distribution to a memory of the first CDS; receiving, at the first CDS, a first content-request transmitted from a first mobile consumer device communicatively coupled to the first CDS; causing a processor of the first CDS to determine whether license-data stored at a memory of the first CDS authorizes delivery, of first content-data from the first collection of encrypted content, responsive to the first content-request; when the processor determines that the license-data authorizes the delivery of the first content-data;
transmitting for reception by the first mobile consumer device, via a communication interface of the first CDS, a key from the first set of keys for decrypting the first content-data. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
