Abstract

A collaborative messaging system and method includes, in a communications engine, a plurality of message interrogators to process a message from a sender to a receiver. The plurality of message interrogators includes a message adjudicator configured to compare message information from the sender with message information obtained by the message adjudicator and to modify the message information from the sender to a more restrictive value. The plurality of message interrogators further includes a message validator configured to allow or deny the message based upon the modified message information.

Claims

1. A collaborative messaging system, comprising:

a communications engine, comprising;

a plurality of message interrogators to process a message from a sender to a receiver, comprising;

a message adjudicator configured to process message information; and

a message validator configured to allow or deny the message based upon the processed message information.

2. The system of claim 1, wherein based upon a comparison of the message information, the message adjudicator is further configured to modify at least a portion of the message information to a more restrictive value.

3. The system of claim 1, wherein based upon a comparison of the message information, the message adjudicator is further configured to modify at least a portion of the message information to a less restrictive value.

4. The system of claim 1, wherein the message adjudicator is further configured to define receiver classification message information to indicate a classification level of the message receiver.

5. The system of claim 1, wherein the message adjudicator is further configured to define sender classification message information to indicate a classification level of the message sender.

6. The system of claim 1, wherein the message adjudicator is further configured to define content classification message information to indicate a classification level of the message content.

7. The system of claim 1, wherein the message adjudicator is further configured to filter the content of the message based upon the processed message information.

8. The system of claim 7, wherein the message adjudicator is further configured to remove at least a portion of the content of the message.

9. The system of claim 8, wherein the at least a portion of removed content is classified material.

10. The system of claim 8, wherein the at least a portion of removed content is offensive material.

11. The system of claim 1, wherein at least a portion of the message information comprises:

receiver classification information to indicate a classification level of the receiver, wherein the message validator is further configured to allow or deny the message based upon the receiver classification information.

12. The system of claim 1, wherein at least a portion of the message information comprises:

content classification information to indicate a classification level of the message content, wherein the message validator is further configured to allow or deny the message based upon the content classification information.

13. The system of claim 1, wherein a portion of the message information comprises:

receiver classification information to indicate a classification level of the receiver, and another portion of the message information comprises;

content classification information to indicate a classification level of the message content, wherein the message validator is further configured to allow or deny the message based upon a comparison of the receiver classification information to the content classification information.

14. A collaborative messaging system, comprising:

a communications engine, comprising;

a plurality of message interrogators to process a message from a sender to a receiver, comprising;

a message adjudicator configured to compare message information from the sender with message information obtained by the message adjudicator and to modify the message information from the sender to a more restrictive value; and

a message validator configured to allow or deny the message based upon the modified message information.

15. The system of claim 14, wherein the message adjudicator is further configured to obtain message receiver information and the message validator is further configured to allow or deny the message based upon the obtained message receiver information.

16. The system of claim 15, wherein the message adjudicator is further configured to filter the message content based upon the modified message information.

17. A collaborative messaging system, comprising:

a communications engine, comprising;

a plurality of message interrogators to process a message from a sender to a receiver, the message comprising message sender information and message content information, comprising;

a message adjudicator configured to;

compare message information from the sender with message information obtained by the message adjudicator, the obtained message information comprising message sender information, message receiver information, and message content information;

modify the message information from the sender to a more restrictive of the message sender information from the sender and the obtained message sender information and the message content information from the sender and the obtained message content information; and

filter the message content based upon the modified message information and the obtained receiver information; and

a message validator configured to allow or deny the message based upon the modified message information and the obtained message receiver information.

18. The system of claim 17, wherein the message adjudicator filters the message content by removing classified material from the message content.

19. The system of claim 17, wherein the message adjudicator filters the message content by removing offensive material from the message content.

20. A collaborative messaging method, comprising:

in a communications engine, processing a message from a sender to a receiver, the message comprising message sender information, message content, and message content information, comprising;

comparing message information from the sender with obtained message information, the obtained message information comprising obtained message sender information, obtained message receiver information, and obtained message content information;

modifying the message information from the sender to a more restrictive value of the message sender information from the sender and the obtained message sender information, and the message content information from the sender and the obtained message content information;

filtering the message content based upon the modified message information and the obtained message receiver information; and

allowing or denying the message based upon the modified message information and the obtained message receiver information.

21. The method of claim 20, further comprising modifying the message information from the sender to a less restrictive value of the message sender information from the sender and the obtained message sender information, and the message content information from the sender and the obtained message content information.

22. The method of claim 20, wherein the message sender information further comprises message sender classification information and the obtained message information further comprises obtained sender classification information, and further comprising:

modifying the message information to a more restrictive value of the message sender classification information and the obtained sender classification information.

23. The method of claim 20, wherein the message content information further comprises message content classification information and the obtained message information further comprises obtained content classification information, and further comprising:

modifying the message information to a more restrictive value of the message content classification information and the obtained content classification information.

24. The method of claim 20, wherein the message information further comprises message receiver classification information and the obtained message information further comprises obtained receiver classification information, and further comprising:

modifying the message information to a more restrictive value of the message receiver classification information and the obtained receiver classification information.

25. The method of claim 20, wherein the message sender information further comprises message sender classification information and the obtained message information further comprises obtained sender classification information, and modifying the message information further comprises modifying the message sender information to a more restrictive value of the message sender classification information and the obtained sender classification information.
