Abstract

A management console may be used to monitor available usage on a pay-per-use electronic device, such as a pay-per-use computer. When the management console determines that any of tie monitored electronic devices has reached a trigger level the management console may re-charge the electronic device with value. The value may be taken from a local pool of value stored at the management console or the an add-value transaction may be generated at the management console on behalf of the pay-per-use electronic device. In an Internet cafe or similar environment, the use of the management console shields individual users from usage purchase transactions for individual pay-per-use electronic devices.

Claims

1. A management console for operation with a plurality of pay-per-use electronic devices comprising:

a network connection allowing connection with the plurality of pay-per-use electronic devices and an add-value service;

a user interface allowing display of metering status for each of the plurality of pay-per-use electronic devices;

a security module comprising;

a secure memory storing keys and an identifier of the security module;

a tamper-resistant clock;

a cryptographic unit for performing cryptographic functions; and

a processor coupled to the secure memory, the tamper-resistant clock and the cryptographic unit,

a computer-readable medium storing computer-executable instructions; and

a main processor coupled to the network connection, the user interface, the security module, the cryptographic unit, and the computer-readable medium, whereby the processor executes the computer-executable instructions to monitor and update the metering status of each of the plurality of electronic devices.

2. The management console of claim 1, wherein the management console is a computer running a management console software application stored in the computer-readable medium.

3. The management console of claim 1, wherein the secure memory stores first keys for authenticating transactions with a fulfillment center and a set of second keys including a respective second key for authenticating transactions with each of the plurality of pay-per-use electronic devices.

4. The management console of claim 3, wherein the secure memory stores a bulk value packet authenticated by the first keys and distributes a portion of the bulk value to one of the plurality of electronic devices by creating a local value packet signed with the respective second key for the that electronic device.

5. The management console of claim 1, wherein the secure memory stores value packets personalized at a distribution center for transfer to a particular one of the plurality of pay-per-use electronic devices.

6. A method of acquiring usage value for a pay-per-use computer by a management console separate from the pay-per-use computer comprising:

monitoring usage value of the pay-per-use computer at the management console;

obtaining usage value on behalf of the pay-per-use computer;

adding usage value to the pay-per-use computer responsive a trigger event corresponding to monitoring the usage value.

7. The method of claim 6, wherein monitoring usage value comprises monitoring data generated at the pay-per-use computer and sent to the management console via a network connection.

8. The method of claim 6, wherein the trigger event is a low-value limit.

9. The method of claim 6, wherein the trigger event is an administrative action.

10. The method of claim 6, wherein the trigger event is a recurring timed event.

11. The method of claim 6, wherein obtaining usage value comprises purchasing a value block stored at the management console for distribution to the pay-per-use computer.

12. The method of claim 11, wherein adding usage value comprises distributing at least a portion the value block to the pay-per-use computer using a key pair established between the management console and the pay-per-use computer.

13. The method of claim 6, wherein obtaining usage value comprises:

signaling the pay-per-use computer to generate a request for usage value;

receiving the request for usage value from the pay-per-use computer; and

forwarding a request for time from the pay-per-use computer to a fulfillment center.

14. The method of claim 13, wherein adding usage value to the pay-per-use computer responsive to the trigger event comprises receiving a usage value packet from the fulfillment center and forwarding the usage value packet to the pay-per-use computer responsive to the trigger event.

15. The method of claim 6, wherein the usage value is usage time.

16. The method of claim 6, wherein the usage value is a subscription period.

17. The method of claim 6, wherein the usage value is timed access to a pay-per-use computer resource.

18. A system for managing pay-per-use electronic devices comprising:

a pay-per-use computer comprising;

a security module comprising;

cryptographic keys for authenticating transactions;

a stored value corresponding to available usage; and

an executable program responsive to a command requesting stored value metrics and further responsive to a second command for processing an add-value packet;

a management console coupled to the pay-per-use computer through a network comprising;

a console security module comprising;

a cryptographic key corresponding to the pay-per-use computer for use in authenticating transactions with the pay-per-use computer;

a fulfillment center coupled to the management console, the fulfillment center having cryptographic keys associated with the pay-per-use computer and the management console for use in authenticating transactions with each, wherein an add value packet generated at the fulfillment center is encrypted with the management console key and designated for re-encrypting at the management console for delivery to the pay-per-use computer.

19. The system of claim 18, wherein the management console further comprises a user interface and computer-executable instructions for requesting and displaying the stored value corresponding to available usage on the pay-per-use computer.

20. The system of claim 18, wherein the management console further comprises computer-executable instructions for decrypting of the add value packet generated at the fulfillment center and re-encrypting the add value packet using a key shared with the pay-per-use computer.
