Abstract

A device is provided for use with a digital content provider and a content purchaser. The content provider can provide digital content and a first digital key, wherein the digital content has quantified digital rights associated therewith. The device includes a receiving portion, a security portion, a content database, an interface portion and a transmitting portion. The receiving portion can receive the digital content and the first digital key. The security portion can access the digital content with the first digital key. The content database can store the digital content. The interface portion can offer to the content purchaser the digital content and can enable the content purchaser to purchase the digital content in accordance with purchased quantified digital rights. The security portion can further encrypt the digital content with a second digital key such that the content purchaser may use the purchased digital content.

Claims

1. A device for use with a digital content provider and a content purchaser, the content provider being operable to provide digital content and a first digital key, the digital content having quantified digital rights associated therewith, the content purchaser being operable to use the digital content in accordance with the digital rights upon receipt of the digital content and a second key, said device comprising:

a receiving portion operable to receive the digital content and the first digital key from the digital content provider;

a security portion operable to access the digital content with the first digital key;

a content database operable to store the digital content;

an interface portion operable to offer to the content purchaser the digital content in accordance with the quantified digital rights and to enable the content purchaser to purchase the digital content in accordance with purchased quantified digital rights that have a quantity that is no more than the quantity of the quantified digital rights; and

a transmitting portion,

wherein said security portion is further operable to encrypt the digital content with a second digital key such that the content purchaser may use the purchased digital content in accordance with the purchased quantified digital rights,

wherein said transmitting portion is operable to transmit the encrypted digital content and the second digital key to the content purchaser.

2. The device of claim 1, wherein said interface portion is further operable to offer to purchase, from the content purchaser, remaining quantified digital rights that have a quantity that is no more than the quantity of the purchased quantified digital rights.

3. The device of claim 2, wherein said a receiving portion is further operable to receive the remaining quantified digital rights from the content purchaser.

4. The device of claim 3, wherein said interface portion is further operable to offer the digital content in accordance with the quantified digital rights, minus the purchased quantified digital rights and plus the remaining quantified digital rights and to enable a second purchase of the digital content in accordance with second purchased quantified digital rights that have a quantity that is no more than the quantity of the quantified digital rights, minus the purchased quantified digital rights and plus the remaining quantified digital rights.

5. The device of claim 4, wherein said security portion is further operable to encrypt the digital content with a third digital key associated with the second purchase.

6. The device of claim 5, wherein said transmitting portion is operable to transmit the encrypted digital content and the third digital key.

7. A method trading digital content rights with a digital content provider and a content purchaser, the content provider being operable to provide digital content and a first digital key, the digital content having quantified digital rights associated therewith, the content purchaser being operable to use the digital content in accordance with the digital rights upon receipt of the digital content and a second key, said method comprising:

receiving, via a receiving portion, the digital content and the first digital key from the digital content provider;

accessing, via a security portion, the digital content with the first digital key;

storing, via a content database, the digital content;

offering, via an interface portion, to the content purchaser the digital content in accordance with the quantified digital rights;

enabling, via the interface portion, the content purchaser to purchase the digital content in accordance with purchased quantified digital rights that have a quantity that is no more than the quantity of the quantified digital rights;

encrypting, via the security portion, the digital content with a second digital key such that the content purchaser may use the purchased digital content in accordance with the purchased quantified digital rights; and

transmitting, via a transmitting portion, the encrypted digital content and the second digital key to the content purchaser.

8. The method of claim 7, further comprising offering, via the interface portion, to purchase, from the content purchaser, remaining quantified digital rights that have a quantity that is no more than the quantity of the purchased quantified digital rights.

9. The method of claim 8, further comprising receiving, via the receiving portion, the remaining quantified digital rights from the content purchaser.

10. The method of claim 9, further comprising:

offering, via the interface portion, the digital content in accordance with the quantified digital rights, minus the purchased quantified digital rights and plus the remaining quantified digital rights; and

enabling, via the interface portion, a second purchase of the digital content in accordance with second purchased quantified digital rights that have a quantity that is no more than the quantity of the quantified digital rights, minus the purchased quantified digital rights and plus the remaining quantified digital rights.

11. The method of claim 10, further comprising encrypting, via the security portion, the digital content with a third digital key associated with the second purchase.

12. The method of claim 11, further comprising transmitting, via the transmitting portion, the encrypted digital content and the third digital key.

13. A device-readable media having device-readable instructions stored thereon, the device-readable instructions being capable of instructing a device to perform a method of trading digital content rights with a digital content provider and a content purchaser, the content provider being operable to provide digital content and a first digital key, the digital content having quantified digital rights associated therewith, the content purchaser being operable to use the digital content in accordance with the digital rights upon receipt of the digital content and a second key, said method comprising:

receiving, via a receiving portion, the digital content and the first digital key from the digital content provider;

accessing, via a security portion, the digital content with the first digital key;

storing, via a content database, the digital content;

offering, via an interface portion, to the content purchaser the digital content in accordance with the quantified digital rights;

enabling, via the interface portion, the content purchaser to purchase the digital content in accordance with purchased quantified digital rights that have a quantity that is no more than the quantity of the quantified digital rights;

encrypting, via the security portion, the digital content with a second digital key such that the content purchaser may use the purchased digital content in accordance with the purchased quantified digital rights; and

transmitting, via a transmitting portion, the encrypted digital content and the second digital key to the content purchaser.

14. The device-readable media of claim 13, the device-readable instructions being capable of instructing the device to further perform offering, via the interface portion, to purchase, from the content purchaser, remaining quantified digital rights that have a quantity that is no more than the quantity of the purchased quantified digital rights.

15. The device-readable media of claim 14, the device-readable instructions being capable of instructing the device to further perform receiving, via the receiving portion, the remaining quantified digital rights from the content purchaser.
