Method and system for multi-domain co-browsing in a C2C co-browse architecture through co-browsing functionality provided in a browser extension on a host

1. A method for co-browsing between multiple parties, comprising:

establishing a first communication session between a first web browser of a first device and a first content provider over a network to deliver content to said first web browser from said first content provider;

downloading to said first device a co-browse extension to said first web browser,

wherein said co-browse extension is configured to host a co-browse session;

accessing said co-browse extension on said first web browser to enable multi-domain co-browsing functionality on said first web browser;

establishing a second communication session between said first web browser and a co-browse communication server to initiate and join said first web browser in a co-browse session, wherein said co-browse session comprises a co-browse session identifier, priority information, and rules, wherein said first device acts as a host in said co-browse session;

identifying the first communication session by the content provider based on the previously received user identifier; and

establishing a third communication session between a second web browser of a second device and said co-browse communication server to join said second web browser into said co-browse session, such that content at said first web browser is delivered to said second web browser of said second device via said co-browse communication server by said embedded co-browsing functionality delivered to said first web browser in said content,

wherein said second device is insulated from receiving direct communication from said content provider, and

wherein said co-browse session allows the host and the guest to display online content from said content provider subject to modifications to a display of said second device for co-browsing depending on said priority information and said rules as defined for the host or the guest.

2. The method of claim 1 , wherein said accessing a co-browse extension further comprises: responsive to request at said first device, enabling said co-browsing functionality at said first device.

3. The method of claim 2 , further comprising: determining that a co-browse icon has been activated on said first device.

4. The method of claim 1 , further comprising: receiving a link comprising said co-browse session identifier at said first web browser from said co-browse communication server, wherein said link when activated directs a corresponding browser to establish communication with said co-browse communication server to join said co-browse session.

5. The method of claim 4 , further comprising: delivering said link to said second device.

6. The method of claim 5 , wherein said delivering said link comprises: pasting said link into a chat conducted between said first device and said second device.

7. The method of claim 5 , wherein said delivering said link comprises: including said link in a message that is delivered from said first device to said second device.

8. The method of claim 4 , wherein said establishing a third communication session comprises: activating said link at said second device.

9. The method of claim 1 , wherein said establishing a third communication session comprises: establishing a fourth communication session between said second web browser and a join page;

entering a token in said join page, wherein said token comprises said co-browse session identifier;

directing said second web browser to said co-browse communication server over said third communication session to join said second web browser into said co-browse session based on said token.

10. The method of claim 1 , further comprising: establishing a fourth communication session between said first web browser of said first device and a second content provider over said network to deliver second content to said first web browser from said second content provider; and

delivering said second content from said first web browser to said second web browser of said second device via said co-browse communication server in said co-browse session.

11. The method of claim 1 , further comprising: establishing a first rules engine at said second device to identify sensitive information, and mask said sensitive information; and

establishing a second rules engine at said first device to identify said sensitive information that is masked.

12. A networked computer system for co-browsing between multiple parties, comprising:

a first web browser of first device configured to establish a communication session with a first content provider over a network to deliver content to said first web browser from said first content provider;

a co-browse extension accessible on said first web browser that enables multi-domain co-browsing functionality on said first web browser;

a co-browse communication server configured to initiate and join said first web browser in a co-browse session, wherein said co-browse session comprises a co-browse session identifier, priority information, and rules, wherein said first device acts as a host in said co-browse session;

identifying the first communication session by the content provider based on the previously received user identifier; and

wherein said co-browse communication server is configured to join said second web browser into said co-browse session, such that content at said first web browser is delivered to said second web browser of said second device via said co-browse communication server by said embedded co-browsing functionality delivered to said first web browser in said content,

wherein said second device is insulated from receiving direct communication from said content provider, and

wherein said co-browse session allows the host and the guest to display online content from said content provider subject to modifications to a display of said second device for co-browsing depending on said priority information and said rules as defined for the host or the guest.

13. The system of claim 12 , further comprising: an icon at said first device that when activated enables said co-browsing functionality at said first device.

14. The system of claim 12 , further comprising: a link comprising said co-browse session identifier delivered to said first web browser from said co-browse communication server, wherein said link when activated directs a corresponding browser to establish communication with said co-browse communication server to join said co-browse session.

15. The system of claim 12 , wherein said link is delivered to said second device.

16. The system of claim 15 , further comprising: a chat conducted between said first device and said second device, wherein said link is pasted into said chat.

17. The system of claim 15 , further comprising: a message including said link that is delivered from said first device to said second device.

18. The system of claim 15 , further comprising:

a fourth communication session established between said second web browser and a join page; and

a token entered into said join page, wherein said token comprises said co-browse session identifier, and

wherein said second web browser is directed to said co-browse communication server over said third communication session to join said second web browser into said co-browse session based on said token.

19. The system of claim 12 , further comprising:

a fourth communication session established between said first web browser of said first device and a second content provider over said network to deliver second content to said first web browser from said second content provider,

wherein said second content is delivered from said first web browser to said second web browser of said second device via said co-browse communication server in said co-browse session.

20. The system of claim 12 , further comprising:

a first rules engine at said second device to identify sensitive information, and mask said sensitive information; and

a second rules engine at said first device to identify said sensitive information that is masked.
