Abstract

Described are a system and method for use by a computing device to transmit information over a communication medium. The computing device communicates over the medium according to a protocol stack having a plurality of protocol layers. Information having an identifier is received at a first protocol layer from a higher protocol layer in the protocol stack. The computing device determines whether to present the information to the network communication medium based on at least one term of a contract associated with the identifier. Upon determining to present the information to the communication medium, the computing device incorporates the identifier in the information before placing the information on the network communication medium.

Claims

1. A method for providing a first computing device with a permission to perform an interaction with a second computing device in a network, the method comprising;

transmitting a first message from the first computing device to the second computing device to initiate an exchange for obtaining the permission to perform the interaction with the second computing device;

automatically selecting by the first computing device a contract corresponding to a type of interaction that is supported by the second computing device to provide the second computing device with the permission to perform the interaction, the contract specifying one or more terms that information associated with the contract must satisfy in order to be transmitted between the first computing device and the second computing device;

transmitting from the first computing device to the second computing device a second message including the contract; and

transmitting a document from the first computing device to the second computing device in accordance with the contract, wherein an identifier is transmitted with the document, the identifier identifying the contract.

2. The method of claim 1, wherein the transmitting of the first message occurs when a predefined key of the first computing device is pressed.

3. The method of claim 1, wherein the transmitting of the first message occurs through an infrared transceiver of the first computing device.

4. The method of claim 1, wherein the first message includes a metadata component indicating content in the first message.

5. The method of claim 1, wherein the transmitting of the first message is a point-to-point transmission directed to a specific transceiver on the second computing device that is dedicated to the type of interaction.

6. The method of claim 1, further comprising transmitting the contract to a resource in the network to enable interaction between the resource and any computing device having the contract.

7. The method of claim 1, wherein the one or more terms specify one or more actions that are permitted to be performed on the information associated with the contract by the first computing device or by the second computing device.

8. The method of claim 1, wherein each of the one or more terms comprises at least one parameter, the at least one parameter comprising at least one of:

a temporal parameter, an information-type parameter, an information-length parameter, and an information-content parameter.

15. The method of claim 1, further comprising:

storing the contract at the first computing device.

16. The method of claim 1, wherein the one or more terms include at least one term that specifies one or more actions that can be performed by the second computing device on information received from the first computing device.

17. The method of claim 1, wherein the type of interaction is a secure type of interaction in which an authenticity and an integrity of at least one of the first computing device and the second computing device is verified.

18. The method of claim 17, wherein the secure type of interaction involves restricting one or more capabilities of at least one of the first computing device and the second computing device.

19. The method of claim 18, wherein the restricting is enforced by a security manager operating locally on the first computing device.

20. The method of claim 18, wherein the secure type of interaction involves at least temporarily restricting a launch of one or more applications on the first computing device.

21. The method of claim 1, wherein the one or more terms are enforced directly by the first computing device and the second computing device.

22. The method of claim 1, wherein the method is implemented within an educational environment.

23. The method of claim 22, wherein the first computing device is operated by a first individual who is a target of an educational assessment, and the second computing device is operated by a second individual who is administering the educational assessment.

24. The method of claim 1, further comprising:

receiving at the first computing device a response to the first message from the second computing device indicating the type of interaction that is supported by the second computing device.

9. A method for providing a permission to perform an interaction with a resource in a network including a first computing device and a second computing device, the method comprising:

receiving at the second computing device a first message from the first computing device to initiate an exchange of the permission with the first computing device;

transmitting by the second computing device a response to the first message to the first computing device indicating a type of interaction that is supported by the second computing device;

receiving at the second computing device a second message from the first computing device including a contract corresponding to the type of interaction to provide the second computing device with the permission to perform the interaction with the resource, the contract specifying one or more terms that information associated with the contract must satisfy in order to be transmitted between the second computing device and the resource in accordance with the interaction with the resource; and

transmitting a document from the second computing device to the resource in accordance with the contract, wherein an identifier is transmitted with the document, the identifier identifying the contract,

wherein the second computing device automatically selects the contract for inclusion with a future message sent by the second computing device to the resource.

10. The method of claim 9, wherein the receiving of the first message occurs through an infrared transceiver of the second computing device.

11. The method of claim 9, wherein the first message includes a metadata component indicating content in the first message.

12. The method of claim 9, wherein the receiving of the first message is a point-to-point communication directed to a specific transceiver on the second computing device that is dedicated to the type of interaction.

13. The method of claim 9, wherein the one or more terms specify one or more actions that are permitted to be performed on the associated information by the first computing device or by the second computing device.

14. The method of claim 9, wherein each of the one or more terms comprises at least one parameter, the at least one parameter comprising at least one of:

a temporal parameter, an information-type parameter, an information-length parameter, and an information-content parameter.
