Abstract

A method of presenting content, in accordance with one embodiment of the present invention, includes receiving a request for an item of content and selectively verifying ownership of the requested content. If verification of ownership is not to be performed for the particular request, the item of content may be served. If ownership is substantiated for the particular request, the content may also be served. If ownership is not substantiated for the particular request, the content may be purged. Ownership verification may be by access to a physical copy of the content (e.g., DVD, CD or the like).

Claims

1. A method of providing content comprising:

Receiving, by a processor, a given request to serve a copy of an item of content on a mass storage device;

selectively verifying ownership of said item of content by access to an original physical medium of the item of content a predetermined multiple number of times, wherein the predetermined multiple number of times is greater than two, over a plurality of times said item of content is requested, wherein said plurality of times is greater than said predetermined multiple number of times and ownership of said item is not verified again if ownership is substantiated said predetermined multiple number of times,

wherein said selectively verifying ownership comprises directly, comparing one or more keys on said original physical medium to one or more encrypted keys hidden on said mass storage device;

wherein said selectively verifying ownership comprises at least a first verification request wherein the first verification request is made a random number of plays after a first fixed period of time and a second verification request wherein the second verification request is made a random number of plays after a second fixed period of time, wherein the second fixed period of time is greater than the first fixed period of time;

serving said item of content for said given request if said verifying ownership is not performed for said given request;

serving said item of content for said given request if ownership is substantiated for said given request by said comparing one or more keys on said original physical medium to one or more encrypted keys hidden on said mass storage device; and

serving said item of content for said given request if ownership has already been substantiated said predetermined multiple number of times.

2. The method according to claim 1, wherein said item of content is digital information and is selected from the group consisting of text, graphics, audio, sound, image, video, movie, music, application, and game.

3. A non-transitory computer readable medium containing a plurality of instructions which when executed cause a system to implement a method of presenting content comprising:

a) Receiving, by a processor, a given request to serve a copy of an item of content on a mass storage device;

b) selectively verifying ownership of said item of content by access to an original physical medium of the item of content a predetermined multiple number of times, wherein the predetermined multiple number of times is greater than two, over a plurality of times said item of content is requested, wherein said plurality of times is greater than said predetermined multiple number of times and ownership of said item is not verified again if ownership is substantiated said predetermined multiple number of times, wherein said selectively verifying ownership comprises directly, comparing one or more keys on said original physical medium to one or more encrypted keys hidden on said mass storage device;

wherein said selectively verifying ownership comprises at least a first verification request wherein the first verification request is made a random number of plays after a first fixed period of time and a second verification request wherein the second verification request is made a random number of plays after a second fixed period of time, wherein the second fixed period of time is greater than the first fixed period of time;

c) serving said item of content for said given request if said verifying ownership is not performed for said given request;

d) serving said item of content for said given request if ownership is substantiated for said given request by said comparing one or more keys on said original physical medium to one or more encrypted keys hidden on said mass storage device; and

e) serving said item of content for said given request if ownership has already been substantiated said predetermined multiple number of times;

f) denying said request for said item of content if ownership is not substantiated at said b) in response to said given request to serve said item of content.

4. The non-transitory computer-readable medium according to claim 3, wherein said method further comprises:

g) purging said item of content if ownership is not substantiated at said b).

5. The non-transitory computer-readable medium according to claim 3, wherein said item of content is selected from the group consisting of text, graphics, audio, sound, image, video, movie, music, application, and game.

6. The non-transitory computer-readable medium according to claim 3, wherein ownership is verified if a key on said physical media corresponds to a key on said mass storage device.

7. The non-transitory computer-readable medium according to claim 3, wherein selectively requesting evidence of ownership of said item of content further comprises requesting evidence after a third random number of requests after a third fixed period of time.

8. The non-transitory computer-readable medium according to claim 7, wherein:

said second fixed period of time is greater than said first fixed period of time; and

said third fixed period of time is greater than said second fixed period of time.

9. A system for storing content comprising:

a content output device;

a mass storage device; and

a processing unit communicatively coupled to said content output device and said mass storage device, wherein said processing unit comprises a content server module for receiving a given request for an item of content stored on said mass storage device, for selectively verifying ownership of said item of content by access to an original physical medium of the item of content a predetermined multiple number of times, wherein the predetermined multiple number of times is greater than two, over a plurality of times said item of content is requested, wherein said plurality of times is greater than said predetermined multiple number of times and ownership of said item is not verified again if ownership is substantiated said predetermined multiple number of times, wherein said selectively verifying ownership comprises directly, comparing one or more keys on said original physical medium to one or more encrypted keys hidden on said mass storage device;

wherein said selectively verifying ownership comprises at least a first verification request wherein the first verification request is made a random number of plays after a first fixed period of time and a second verification request wherein the second verification request is made a random number of plays after a second fixed period of time, wherein the second fixed period of time is greater than the first fixed period of time;

serving said item of content for said given request if said verifying ownership is not performed for said given request;

serving said item of content for said given request if ownership is substantiated for said given request by said comparing one or more keys on said original physical medium to one or more encrypted keys hidden on said mass storage device; and

serving said item of content for said given request if ownership has already been substantiated said predetermined multiple number of times.

10. The system of claim 9, further comprising a content input device communicatively coupled to said processing unit for said receiving said reinsertion of said original physical medium of said item of content.

11. The system of claim 9, wherein said content server module further serves said item of content for said given request if said verifying ownership is not performed for said given request.

12. The system of claim 9, wherein said content server module further purges said requested item of content if ownership is not substantiated.

13. The system of claim 9, wherein said content output device comprises one or more devices selected from the group consisting of a display, a monitor, a television, a projector, a speaker, a headphone and a Braille reader.

14. The system of claim 9, wherein said mass storage device comprises a hard disk drive.
