Abstract

Methods, devices, and systems are provided in a multi-level computer architecture which provides improved capabilities for managing courseware and other content in a shared use operating environment such as a computer network. In particular, the invention provides a commercial networked instruction content delivery method and system which does not exclude synchronous sharing but is focused on asynchronous sharing. Security in the architecture provides content property holders with the ability to know how many minutes of use an individual made of licensed material and with increased certainty that their material cannot be used, copied, or sold in usable form unless lo and until a user site is connected or reconnected to a minute-by-minute counter which is located off the premises of the user. This security link helps protect software and other works which are being sold or licensed to an individual, organization, or entity, and creates income opportunities for owners of such content.

Claims

1. A method for managing content in a shared use operating environment, the shared use operating environment including a registration server, a content server connectable by a network link to the registration server, and a client workstation connectable by a client-server network communications link to the content server, the method comprising the steps of:

registering a user at the registration server, thereby characterizing the user as a registered user;

receiving at the content server a request by the registered user for access to content which contains at least one previously treated critical portion;

authenticating the request;

serving at least the critical portion over the client-server network communications link for presentation to the registered user at the client workstation; and

metering usage of the content by the registered user.

2. The method of claim 1, further comprising the step of treating the critical portion, thereby enabling enhanced intellectual property right protection of the content by technical means.

3. The method of claim 2, wherein the treating step comprises inserting disabling code into an executable portion of courseware content.

4. The method of claim 2, wherein the treating step comprises encapsulating the critical portion in a database table.

5. The method of claim 1, further comprising the step of monitoring the client-server network communications link.

6. The method of claim 5, further comprising the step of disabling use of at least a portion of the content after an expected security handshake is not received.

7. The method of claim 1, further comprising the step of presenting the registered user with an invoice for usage of the content.

8. The method of claim 7, further comprising the step of allowing a local administrator to adjust the invoice presented to the user in response to a request by the user for an adjustment.

9. The method of claim 1, further comprising the step of downloading at least one non-critical portion of the content to the client workstation at least two hours before serving the critical portion.

10. The method of claim 1, further comprising the step of disabling caching and other disk writes to prevent a copy of the critical portion of the content from being created on nonvolatile storage at the client workstation.

11. The method of claim 1, further comprising the step of obtaining a credit card payment authorization to permit payment by credit card for usage of the content.

12. The method of claim 1, further comprising the step of reserving a particular piece of courseware content for a particular registered user.

13. A computer storage medium having a configuration that represents data and instructions which will cause at least a portion of a multi-level computer system to perform method steps for managing courseware in a shared use operating environment, the shared use operating environment including a server and a client connectable by a network communications link to the server, the method comprising the steps of:

receiving at the server a request by a registered user for access to courseware which contains at least one previously treated critical portion;

serving at least the critical portion over the network communications link for presentation to the registered user at the client; and

monitoring the network communications link to prevent unauthorized use of the courseware.

14. The configured storage medium of claim 13, wherein the method further comprises the step of treating the critical portion, thereby enabling enhanced intellectual property right protection of the courseware.

15. The configured storage medium of claim 14, wherein the treating step comprises inserting disabling code into an executable portion of the courseware.

16. The configured storage medium of claim 14, wherein the treating step comprises encapsulating the critical portion in a database table.

17. The configured storage medium of claim 13, wherein the method further comprises the step of presenting an invoice for usage of the courseware.

18. The configured storage medium of claim 17, wherein the method further comprises the step of allowing a local administrator to adjust the invoice presented.

19. The configured storage medium of claim 13, wherein the method further comprises the step of downloading at least one non-critical portion of the courseware to the client at least one hour before serving the critical portion.

20. The configured storage medium of claim 13, wherein the method further comprises the steps of metering usage of the courseware and charging for metered usage.

21. The configured storage medium of claim 13, wherein the method further comprises the step of disabling disk writes to reduce the risk that a copy of the critical portion of the courseware will be created on nonvolatile storage at the client.

22. The configured storage medium of claim 13, wherein the method further comprises the step of reserving with a guarantee a particular piece of courseware for a particular user.

23. A multi-level computer architecture for managing content in a shared use operating environment, the content containing at least one previously treated critical portion, the architecture including:

a registration server level including at least one registration server, each registration server comprising a remote registration manager and a registration database for new user registration, and each registration server being further characterized in that it is free of content managed by the architecture;

a content server level including at least one content server, each content server linked for network communications with a registration server, each content server containing content managed by the architecture, the content containing at least one previously treated critical portion, and each content server being further characterized in that it serves such content critical portions only for presentation to registered users, namely, users who have previously been registered with a registration server; and

a client level including at least one client workstation, each client workstation connectable to a content server by a client-server network communications link, and each client workstation being further characterized in that it presents to at least one registered user a content critical portion which is served over the client-server network communications link by the content server.

24. The computer architecture of claim 23, further comprising a security manager for preventing unauthorized use of the content.

25. The computer architecture of claim 24, wherein a portion of the security manager resides on each client workstation and a portion resides on each content server.

26. The computer architecture of claim 24, wherein critical portions of the content reside in database tables managed by the security manager.

27. The computer architecture of claim 24, wherein the security manager is further characterized in that it sends at least part of a critical portion of content only to a volatile client workstation memory rather than sending it to a nonvolatile client workstation memory.

28. The computer architecture of claim 23, wherein the registration server further includes a reservation manager and a reservation database which permits registered users to reserve content.

29. The computer architecture of claim 28, further comprising a funds flow manager for managing payment information, wherein the reservation manager, the reservation database, or both, operate with the funds flow manager to provide registered users with guaranteed content reservations.

30. The computer architecture of claim 23, further comprising a funds flow manager for managing content usage payment information.

31. The computer architecture of claim 30, wherein a portion of the funds flow manager resides on each client workstation, a portion resides on each content server, and a portion resides on each registration server.
