Abstract

A system is provided for automatically enforcing communication policy rules for document sharing between a communication server and a publishing server. The system may enable a policy agent to examine a communication containing a document attachment before the communication may be delivered to a recipient. The policy agent may evaluate the communication against communication policy rules, and if the policy agent determines that the communication policy rules are not violated, then a document upload agent may transfer the attached document to the publishing server. The system may then deliver the communication message to the recipient. If the policy agent determines that the communication policy rules are violated, then the system may prevent the document upload agent from transferring the attached document to the publishing server and may continue to deliver the communication to the recipient without the document attachment.

Claims

1. A method executed at least in part in a computing device for enforcing communication policy rules for document sharing in a collaborative environment, the method comprising:

detecting a communication associated with a document from a sender to a designated recipient through a communication server in the collaborative environment;

determining a communication policy rule associated with the communication; and

applying the communication policy rule to at least one from a set of;

a storage, an access, and a distribution of the document within the collaborative environment.

2. The method of claim 1, further comprising:

if the communication does not violate the communication policy rule, then enabling automatic uploading of the document to a publishing server;

delivering the communication to the designated recipient; and

enabling the designated recipient to access the document through the publishing server.

3. The method of claim 1, further comprising:

if the communication does violate the communication policy rule, then preventing the document from being uploaded to a publishing server; and

preventing the communication from being delivered to the designated recipient.

4. The method of claim 1, further comprising:

employing a policy agent that resides at the communication server for determining if the communication violates the communication policy rule; and

employing an upload agent that resides at the communication server for automatically uploading the document to a publishing server if the communication does not violate the communication policy rule.

5. The method of claim 4, further comprising:

applying the policy agent to the communication upon initial receipt of the communication at the communication server; and

releasing the communication from the policy agent to the upload agent for automatic uploading of the document to the publishing server if the communication does not violate the communication policy rule.

6. The method of claim 1, wherein the document is attached to the communication.

7. The method of claim 6, further comprising:

if the communication does not violate the communication policy rule, removing the attached document from a body of the communication;

transferring the document to a document repository; and

storing the body of the communication separately at the communication server.

8. The method of claim 7, further comprising:

replacing the attached document in the body of the communication with a link to the stored document in the document repository prior to forwarding the communication to the designated recipient.

9. The method of claim 6, further comprising:

if the communication does violate the communication policy rule, then;

removing the attached document from the communication; and

enabling the communication server to deliver the communication to the designated recipient without the attached document.

10. The method of claim 6, further comprising:

if the communication does violate the communication policy rule, then;

removing the attached document from the communication;

enabling the communication server to modify the communication to indicate that the communication violates the communication policy rule; and

enabling the communication server to deliver the modified communication to the designated recipient.

11. The method of claim 1, further comprising:

if the communication does violate the communication policy rule, generating a message informing the sender that the communication was not delivered.

12. A communication server for enforcing communication policy rules for document sharing in a collaborative environment, comprising:

a memory storing instructions;

a processor coupled to the memory, the processor executing a communication application, wherein the communication application is configured to;

receive a communication associated with a document from a sender to a designated recipient;

employ a policy agent to determine if the communication violates the communication policy rule;

if the communication does not violate the communication policy rule, then;

release the communication from the policy agent to an upload agent for automatic uploading of the document to a publishing server;

deliver the communication to the designated recipient; and

enable the designated recipient to access the document through the publishing server.

13. The communication server of claim 12, wherein the communication application is further configured to:

if the communication does violate the communication policy rule, then;

prevent uploading of the document to the publishing server; and

one of;

prevent delivery of the communication to the designated recipient and forward a message to at least one of the designated recipient and the sender indicating that the communication violates the communication policy rule.

14. The communication server of claim 12, wherein the communication includes at least one from a set of:

an e-mail message, a text message, an online conference exchange, a whiteboard sharing exchange, a desktop sharing exchange, and application sharing exchange.

15. The communication server of claim 12, wherein the policy agent and the upload agent are implemented as independent modules for enforcing the communication policy rule.

16. The communication server of claim 12, wherein the communication application is further configured to:

apply the upload agent first upon receipt of the communication by the communication server to automatically upload the document to the publishing server;

apply the policy agent next to determine if the communication policy rule is violated; and

if the policy agent determines that the communication policy rule is violated, prevent the communication server from delivering the communication to the designated recipient.

17. The communication server of claim 16, wherein the communication application is further configured to:

if the policy agent determines that the communication policy rule is violated, enable the policy agent to flag the uploaded document at the publishing server; and

enable the publishing server to set permission and access settings to prevent unauthorized users from accessing the uploaded document at the publishing server.

18. The communication server of claim 12, wherein the document includes one of:

a word processing document, a spreadsheet document, a presentation document, an audio file, a video file, an email message, a calendar item, and a graphic file.

19. A computer-readable memory device with instructions stored thereon for enforcing communication policy rules for document sharing between a communication server and a publishing server in a collaborative environment, the instructions comprising:

receiving a communication associated with a document from a sender to a designated recipient through a communication server in the collaborative environment;

determining a communication policy rule associated with the communication; and

employing a policy agent that resides at the communication server for determining if the communication violates the communication policy rule;

if the communication does not violate the communication policy rule, then;

employing an upload agent that resides at the communication server for automatically uploading the document to the publishing server; and

delivering the communication to the designated recipient;

if the communication does violate the communication policy rule, then;

preventing the document from being uploaded to a publishing server;

preventing the communication from being delivered to the designated recipient; and

generating a message informing at least one of the designated recipient and the sender that the communication was not delivered.

20. The computer-readable memory device of claim 19, wherein the communication policy rule includes one or more of:

specifying that communication between predefined users and groups is prohibited, document sharing between predefined users and groups is prohibited, communication including confidential content is prohibited, communication including illegal content is prohibited, and communication including offensive content is prohibited.
