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. Further, each content-delivery system may generate an authorization-token that can be transmitted to other systems in the content-delivery network, enabling the other systems to quickly determine that a request to resume a previous content-delivery session has already been authorized.

First claim

What is claimed is:

1 . A computer-implemented method for verifying access-rights to content, the method comprising:
authorizing, at a content-delivery system (“CDS”) disposed on a vehicle, a content-delivery session to deliver to a mobile consumer device content selected from a collection of content (“selected content”); transmitting, from the CDS to the mobile consumer device, one or more keys for decrypting encrypted content-data received by the mobile consumer device during the content-delivery session, the encrypted content-data representing the selected content; generating, at the CDS, an authorization-token associated with the authorized content-delivery session and transmitting the authorization-token; receiving, at a data center, the authorization-token; receiving, at the data center, a request to resume the content-delivery session; authorizing or denying by the data center, based on the authorization-token, the requested resumption of the content-delivery session; and when the requested resumption is authorized: transmitting one or more keys for decrypting encrypted content-data representing the selected content.

2 . The method of claim 1 , wherein authorizing or denying, based on the authorization-token, the requested resumption of the content-delivery session, comprises:
analyzing (i) the authorization-token and (ii) session-data received in association with the request to resume.

3 . The method of claim 2 , wherein generating the authorization-token comprises:
calculating a first hash value to be included in the authorization-token, said calculating including evaluating a hash function for a first input, the first input including session-data relating to the authorized content-delivery session.

4 . The method of claim 3 , wherein the session-data relating to the authorized content-delivery session comprises one or more of:
(i) an identifier for the selected content, (ii) an identifier for a user, (iii) an identifier for the mobile consumer device, (iv) a product identifier, or (iv) a catalog identifier.

5 . The method of claim 3 , wherein the session-data relating to the authorized content-delivery session comprises one or more of:
(i) a location logged by the first CDS during the content-delivery session, (ii) an origin location for the vehicle, or (iii) a destination location for the vehicle.

6 . The method of claim 3 , wherein analyzing (i) the authorization-token and (ii) session-data received in association with the request to resume comprises:
calculating a second hash value by evaluating the hash function for a second input, the second input including the session-data received in association with the request to resume; and comparing the first hash value included in the authorization-token to the second hash value.

7 . The method of claim 6 , wherein authorizing or denying the requested resumption of the content-delivery session comprises:
authorizing the requested resumption of the content-delivery session when first hash value matches the second hash value; said authorizing including: generating or updating a license record, stored to memory, to indicate that the content-delivery session is authorized.

8 . The method of claim 7 , wherein generating or updating a license record, stored to memory, to indicate that the content-delivery session is authorized comprises:
specifying content that is authorized to be delivered during the content-delivery session by logging an identifier for the selected content; and specifying an identity authorized to receive content via the content-delivery session by logging at least one of: a user identifier for a particular user; or a device identifier for a particular device.

9 . The method of claim 1 , further comprising:
receiving payment-data representing payment for the selected content wherein authorizing, at the CDS, the content-delivery session to deliver to the mobile consumer device the selected content includes: generating or updating a license record to indicate that the content-delivery session is authorized.

10 . The method of claim 1 , wherein transmitting the authorization-token comprises:
transmitting the authorization-token to the mobile consumer device; wherein receiving, at the data center, the authorization-token includes: receiving the authorization-token from the mobile consumer device.

11 . The method of claim 1 , wherein generating, at the CDS, an authorization-token associated with the authorized content-delivery session and transmitting the authorization-token comprises:
generating the authorization-token while the first CDS is operating in autonomous mode.

12 . A content-delivery system (“CDS”) for a content-delivery network, the CDS disposed at a vehicle for delivering content to a mobile consumer device, the CDS comprising:
one or more processors;
a communication interface;
one or more memory devices including (i) a collection of content that was loaded to the CDS and (ii) computer readable instructions that, when executed by the one or more processors, cause the CDS to:
authorize a content-delivery session for transmitting to a mobile consumer device: (i) encrypted content-data representing the selected content, and (ii) one or more keys for decrypting the encrypted content-data;
generate an authorization-token associated with the authorized content-delivery session; and
transmit via the communication interface the authorization-token for use by a data center, the data center configured to receive a request to resume the content-delivery session and to determine whether the requested resumption is authorized based on the authorization-token.

13 . The CDS of claim 12 , wherein the communication interface is configured to transmit and receive at least one of: (i) wireless signals having a frequency under approximately 1 GHz, or (ii) wireless signals having a frequency between approximately 2.4 GHz and approximately 5 GHz.

14 . The CDS of claim 12 , wherein the instructions that cause the CDS to authorize the content-delivery session include instructions that, when executed, cause the CDS to:
generate or update, after receiving payment-data representing payment for the selected content, a license record to indicate that the content-delivery session is authorized.

15 . The CDS of claim 12 , wherein the instructions that cause the CDS to generate an authorization-token associated with the authorized content-delivery session include instructions that, when executed, cause the CDS to:
calculate a first hash value to be included in the authorization-token by evaluating a hash function for a first input, the first input including session-data relating to the authorized content-delivery session; wherein the data center is configured determine whether the request to resume is authorized by comparing the first hash value included in the authorization token to a second hash value calculated from session-data received in association with the request to resume.

16 . The CDS of claim 12 , wherein the instructions that cause the CDS to transmit via the communication interface the authorization-token for use by a data center include instructions that, when executed, cause the CDS to:
transmit the authorization-token to the mobile consumer device, wherein the mobile consumer device is configured to upload the authorization-token to the data center.

17 . A data center for a content-delivery network, the data center comprising:
one or more processors; one or more memory devices storing a content-library including content available
