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.

Claims20

Dependent claims

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, and
(iii) authorize content delivery without communicating with the license server, wherein the first proxy license server is configured to:
when the license-data does not authorize delivery of the first content-data:
(a) update the license-data to authorize delivery of the first content-data, and (b) transmit, for reception by the first mobile consumer device, the key from the first set of keys for decrypting the first content-data.

11 more elements

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;
when (i) the license-data does not authorize the delivery of the first content-data, and (ii) the first CDS is not in communication with the license server:
(a) updating the license-data to authorize delivery of the first content-data;
and
(b) transmitting, for reception by the first mobile consumer device, the key from the first set of keys for decrypting the first content-data.
