Abstract

A content distribution system for controlling access of digital content that is shared with indirect contacts receives from a publisher of digital content, a specification of a sharing policy for sharing by a first user to indirect contacts to be identified at the time of distribution. The sharing policy can identify a number of shares, a number of indirect contacts, acceptable web domains, or acceptable geographic regions. The system receives a request from the first user to access the content. The first user is a contact of the publisher identified by the publisher. The system authorizes the first user to access the content and receives from the first user a request to share the content with a second user that is a contact of the first user and an indirect contact of the publisher. The system authorizes, in accordance with the sharing policy, the second user to access the content.

Claims

1. A method for sharing digital content via the content distribution system while maintaining control over access to the digital content, the method comprising:

(a) receiving, via a content distribution system having one or more processors, from a publisher of digital content, configuration of a sharing policy for sharing the digital content;

(b) receiving, by the content distribution system, a first request of a first user to access the digital content;

(c) providing, by the content distribution system access to the first user, to the digital content;

(d) receiving, by the content distribution system, a second request of the first user to share the digital content with a second user;

(e) determining, by the content distribution system, based on the sharing policy, that the first user is authorized to share the digital content with the second user; and

(f) providing, by the content distribution system, access to the second user to the digital content responsive to the determination.

2. The method of claim 1, wherein (a) further comprises specifying, by the publisher via the content distribution system, identification of a specific user to receive access to the digital content via the content distribution system and a predetermined number of devices for the specific user.

3. The method of claim 2, wherein (a) further comprises specifying, by the publisher via the content distribution system, a geographical limitation on a location at which devices of the predetermined number of devices are authorized to access the digital content.

4. The method of claim 2, wherein (a) further comprises specifying, by the publisher via the content distribution system, a dynamic expiration of when devices of the predetermined number of devices are authorized to access the digital content, the dynamic expiration comprising one of a given number of days or a scheduled date upon which the digital content is no longer accessible without further action by the publisher.

5. The method of claim 1, wherein (b) further comprises receiving, by the content distribution system, the first request responsive to the first user receiving a communication that the digital content is available at the content distribution system.

6. The method of claim 1, wherein (c) further comprises identifying, by the content distribution system, that a device associated with the first user has not been assigned a unique device identifier generated by the content distribution system.

7. The method of claim 1, wherein (d) further comprises identifying, by the content distribution system, that a number of unique device identifiers generated for the digital content has reached a same number as the predetermined number of devices.

8. The method of claim 7, wherein receiving the second request to share the digital content with the second user comprises denying, by the content distribution system, the second user access to the digital content responsive to identifying that the number of unique device identifiers generated for the digital content has reached a same number as the predetermined number of devices.

9. The method of claim 1, further comprising:

receiving, by the content distribution system, a third request of a device to access the digital content, the device previously activated by the content distribution system as one of a predetermined number of devices authorized to access the digital content; and

providing, by the content distribution system, access to the device to the digital content.

10. The method of claim 1, further comprising:

receiving, by the content distribution system, a third request of a device to access the digital content;

determining by the content distribution system, that one of a geographical location of the device or time of access by the device does not meet the sharing policy specified by the publisher for the digital content; and

restricting the device from accessing the digital content responsive to the determination.

20. The system of claim 1, wherein the digital content manager is further configured to:

receive a third request of a device to access the digital content;

determine that one of a geographical location of the device or time of access by the device does not meet the sharing policy specified by the publisher for the digital content; and

restrict the device from accessing the digital content.

11. A system for sharing digital content via the content distribution system while maintaining control over access to the digital content, the system comprising:

a content distribution system including a memory and one or more processors, the content distribution system including

a policy engine configured to receive configuration of a sharing policy for sharing digital content;

a digital content manager configured to

receive a first request of a first user to access the digital content;

provide, to the first user, access to the digital content;

receive a second request of the first user to share the digital content with a second user;

determine, based on the sharing policy, that the first user is authorized to share the digital content with the second user; and

provide access to the second user to the digital content responsive to the determination.

12. The system of claim 11, wherein the configuration specifies an identity of a specific user to receive access to the digital content via the content distribution system and a predetermined number of devices for the specific user.

13. The system of claim 12, wherein the configuration specifies a geographical limitation on a location at which devices of the predetermined number of devices is authorized to access the digital content.

14. The system of claim 12, wherein the configuration specifies a dynamic expiration of when devices of the predetermined number of devices are authorized to access the digital content, the dynamic expiration comprising one of a given number of days or a scheduled date upon which the digital content is no longer accessible without further action by the publisher.

15. The system of claim 11, wherein to receive the first request of the first user to access the digital content, the digital content manager is further configured to receive the first request responsive to the first user receiving a communication that the digital content is available at the content distribution system.

16. The system of claim 11, wherein to provide, to the first user, access to the digital content, the digital content manager is further configured to identify that a device associated with the first user has not been assigned a unique device identifier generated by the content distribution system.

17. The system of claim 11, wherein to receive the second request to share the digital content with the second user, the digital content manager is further configured to identify that a number of unique device identifiers generated for the digital content has reached a same number as the predetermined number of devices.

18. The system of claim 17, wherein to receive the second request to share the digital content with the second user, the digital content manager is further configured to deny the second user access to the digital content responsive to identifying that the number of unique device identifiers generated for the digital content has reached a same number as the predetermined number of devices.

19. The system of claim 11, wherein the digital content manager is further configured to:

receive a third request of a second device to access the digital content, the device previously activated by the content distribution system as one of a predetermined number of devices authorized to access the digital content; and

provide access to the device to the digital content to the second device.
