## Title
Co-browsing a page including clippable and non-clippable portions

## Abstract

Methods and systems of co-browsing may provide for detecting a selection of clipped content at a local peer device during a co-browsing session between the local peer device and a remote peer device. The clipped content can correspond to a page from a server associated with the co-browsing session. Dependent content and style element data associated with the clipped content may be identified, wherein an event can be sent to the remote peer device via the server. The event may include the clipped content, the dependent content, and the style element data.

## Background
BACKGROUND
1. Technical Field
Embodiments of the present invention generally relate to co-browsing sessions. More particularly, embodiments relate to page clipping during co-browsing sessions.
2. Discussion
Web widgets may support peer-to-peer co-browsing sessions in which two users share viewed pages and may even highlight portions of the pages. There are some scenarios, however, in which both users cannot view the same page (e.g., page contains personalized content) or a particular user does not want the entire page to be visible to the other user (e.g., page contains sensitive content).
BRIEF SUMMARY
Embodiments may provide for a computer program product including a computer readable storage medium and computer usable code stored on the computer readable storage medium. If executed by a processor, the computer usable code causes a computer to detect a selection of clipped content at a local peer device during a co-browsing session between the local peer device and a remote peer device. The clipped content can correspond to a page from a server associated with the co-browsing session. The computer usable code, if executed, may also identify dependent content and style element data associated with the clipped content, and send an event to the remote peer device via the server. The event can include the clipped content, the dependent content and the style element data. In one example, the local peer device withholds content in the page other than the clipped content, the dependent content and the style element data.
Embodiments may also provide for a computer program product including a computer readable storage medium and computer usable code stored on the computer readable storage medium. If executed by a processor, the computer usable code causes a computer to establish a co-browsing session between a first peer device and a second peer device, and to transmit a page to the first peer device. The computer usable code, if executed, can also cause a computer to receive an event from the first peer device, wherein the event includes clipped content, dependent content associated with the clipped content and style element data associated with the clipped content. In addition, the computer usable code may provide for transmitting the event to the second peer device.
Other embodiments can include a computer program product including a computer readable storage medium and computer usable code stored on the computer readable storage medium. If executed by a processor, the computer usable code causes a computer to receive an event at a local peer device during a co-browsing session between the local peer device and a remote peer device. The event may include clipped content, dependent content associated with the clipped content, and style element data associated with the clipped content. The computer usable code, if executed, can also cause a computer to open a page, apply the style element data to the page, add the clipped content and the dependent content to the page, and display the page at the local peer device.

Referring now to FIG. 1, a networking architecture 10 is shown in which a server 12 includes logic 14 to establish and maintain a co-browsing session between a first user equipment (UE) device 16 and a second UE device 18, as well as to support page clipping between the UE devices 16, 18. The UE devices 16, 18 can also include logic 22 to participate in co-browsing sessions and share clipped portions of pages with one another. In the illustrated example, the UE devices 16, 18, which may include web browsing capability and can function as peer devices in co-browsing sessions, may include a personal computer (PC), notebook computer, personal digital assistant (PDA), wireless smartphone, or other device having access to the server 12, via a network 20. The UE device connection to the network 20 may include a wireless data connection (e.g., IEEE 802.11, 1999 Edition, LAN/MAN Wireless LANS (WiFi), IEEE 802.16-2004, LAN/MAN Broadband Wireless LANS (WiMAX), etc.), a cellular telephone connection (e.g., W-CDMA (UMTS), CDMA2000 (IS-856/IS-2000), etc.), a wired data connection (e.g., RS-232 (Electronic Industries Alliance/EIA), Ethernet (e.g., IEEE 802.3-2005, LAN/MAN CSMA/CD Access Method), power line communication (e.g., X10, IEEE P1675), USB (e.g., Universal Serial Bus 2.0 Specification)), etc., depending upon the circumstances. The UE devices 16, 18 and/or server 12 could be located in the same physical location or in different locations.
In addition, the network 20 can include any suitable combination of servers, access points, routers, base stations, mobile switching centers, public switching telephone network (PSTN) components, etc., to facilitate communication between the UE devices 16, 18 and the server 12. The server 12 may include distributed and/or redundant web-based servers that are able to respond to web page requests for content. Thus, the server 12 can have stored thereon hypertext markup language (HTML) and other markup language-encoded content, as well as databases and applications such as Java and other applications. The server 12 could also be part of a cloud computing environment in which resources are shared across platforms in a complex fashion.
Generally, each UE device 16, 18 uses the logic 22 to enable a user to select clipped content from a displayed page and share the clipped content, as well as it's associated dependent content and style element data, with the other UE device 16, 18. As will be discussed in greater detail, content in the page other than the clipped content and its associated dependent content and style data can be withheld from the other UE device 16, 18.
FIG. 2 shows a method 24 in which clipped content is shared between peer devices. The method 24 could be implemented in executable software as a set of logic instructions stored in a machine- or computer-readable medium such as random access memory (RAM), read only memory (ROM), programmable ROM (PROM), flash memory, etc., as fixed-functionality hardware using circuit technology such as application specific integrated circuit (ASIC), complementary metal oxide semiconductor (CMOS) or transistor-transistor logic (TTL) technology, or any combination thereof.
Processing block 26 provides for establishing a co-browsing session between a first peer device and a second peer device. The co-browsing session might be initiated by either the first or second peer device by activating an appropriate web widget or other application software. In the illustrated example, the first peer device transmits a page request to the server hosting the co-browsing session at block 28, wherein the server can receive the page request at block 30 and respond with the requested page at block 32. The transmitted page could relate to a wide variety of activities including, but not limited to, electronic commerce (e-commerce), multimedia, gaming, business-to-business (B2B), and so on. Moreover, the page could be generated locally at the first peer device using Java or other similar programming languages. In one example, the page includes content that is personalized with respect to the first peer device (e.g., shopping cart or other cookie-based content) so that the personalized content is not readily available to the second peer device. The page might also include sensitive content such as passwords, account numbers, etc., that the user of the first peer device may not wish to disclose to the second peer device during the co-browsing session.
Upon receipt of the page at block 34, the first peer device may identify “clippable” and “non-clippable” portions of the page at block 36. A clippable portion of the page can be considered to include any content on the page that may be clipped and shared with another peer in a co-browsing session. Certain content such as sensitive content might be flagged as non-clippable and withheld from clip sharing operations. The identification at block 36 could be implemented in a number of different ways. For example, a web application might be invoked to identify the clippable portion and/or the clippable portion could be identified based on one or more tags in the page. Moreover, a transparent division (div, e.g., grayed out overlay) may be applied to the non-clippable portion of the page to aid the user of the first peer device in clipping content from the page and to facilitate easier collaboration between peers. For example, the transparent div could be applied to any sensitive content that should not be shared in the co-browsing session. Block 38 provides for displaying the page in a browser such as Firefox from Mozilla, Internet Explorer from Microsoft, etc.
If a selection of clipped content from the page is detected at block 40, block 42 provides identifying dependent content associated with the clipped content. In particular, the illustrated approach could access the nested hierarchy of HTML code in the page (e.g., using the innerHTML property) to identify the children of the clipped content in the hierarchy. The dependent content might also include position and size information to ensure that the clipped content can be placed in the proper location of the page by the other peer device. In addition, the clipped content can be parsed to identify the style element data such as cascading style sheet (CSS) elements and CSS rules associated with the clipped content. The style element data can enable an accurate reproduction of the clipped content at the other end of the co-browsing session. The style of the page might also be modified in the page at the first peer device in order to highlight the currently clipped content (and its dependent content) to the user of the first peer device. The highlighting style information could be incorporated with the other CSS elements and CSS rules into the style element data.
Illustrated block 44 provides for generating a clip event based on the clipped content, as well as the dependent content and the style element data associated with the clipped content. The generated event may be sent to the server associated with the co-browsing session, wherein block 46 provides for receiving the clip event at the server and transmitting the clip event to the second peer device. The clip event can be received by the second peer device at block 48. Illustrated block 50 provides for opening a blank page, wherein the style element data included in the clip event may be applied to the blank page at block 52. In addition, the clipped content and the dependent content can be added to the style-formatted page at block 54. The process at block 54 could also include implementing any position and sizing information contained in the clip event in order to position the clipped content in the proper location. Block 56 provides for displaying the constructed page at the second peer device.
Turning now to FIGS. 3A and 3B, pages 58 and 60 are shown for a first peer device and a second peer device, respectively. Each of the illustrated pages 58, 60 includes an address bar 62 and one or more control buttons 64 to initiate a variety of co-browsing related functions such as clipping content (e.g., a “Highlight” button), sending clipped content (e.g., a “Send Page” button), inviting other peer devices to follow the local peer device (e.g., a “Follow Me” button), and granting remote control over the local peer device (e.g., a “Grant Control” button). In addition, each page 58, 60 may generally include a clippable portion and a non-clippable portion, wherein users can clip and share content from the clippable portion and content from the non-clippable portion can be withheld from clipping operations in a co-browsing session. For example, the illustrated page 58 of the first peer device has a clippable portion 66 (66a-66b), wherein the remainder of the page 58 is non-clippable. Thus, the non-clippable portion might include sensitive content 68, such as passwords, account numbers, account balances, etc., that the user of the first peer device may wish to prevent from view on the second peer device. A transparent div could be placed over the non-clippable portion of the page to prevent clipping of unwanted areas of the page.
Moreover, the clippable portion 66 could include content that is customized with respect to the first peer device and not readily accessible by the second peer device. For example, the clippable portion 66a could include a shopping basket generated by the user of the first peer device while browsing an e-commerce web site, and the clippable portion 66b might include an indication of more buying choices that is generated by a web application based on the shopping history and/or preferences of the user of the first peer device. Thus, if the user of the second peer device navigates to the same address of the page 58, the content in the clippable portions 66 may not be viewable or shown in the page 60 displayed in the browser of the second peer device because the content in the clippable portions 66 is customized to the user of the first peer device. Indeed, the page 60, which may be for the same web page address as page 60 or a different address, includes a different clippable portion 70 (70a-70b) and non-clippable portion with sensitive content 72 altogether.
FIGS. 4A and 4B demonstrate that the user of the first peer device may make a selection from the page 58, so that the clippable portion 66a (FIG. 3A) becomes clipped content 74. The selection could be made by a mouse over, click, box drag, etc., and/or by selecting a “Highlight” button from the control buttons 64. The other clippable portion 66b might also be selected concurrently with the clippable portion 66a (FIG. 3A) or subsequent to the selection of the clippable portion 66a (FIG. 3A). In the illustrated example, the style of the clipped content 74 is modified to highlight the selection to the user of the first peer device. As already noted, the selection of the clipped content 74 may initiate an identification of the dependent content in the page 58 associated with the clipped content 74, as well as an identification of any style element data (e.g., CSS elements, CSS rules, etc.) associated with the clipped content 74. The dependent content, which could include position and size information for the clipped content 74, might be identified through the use of the inner HTML property.
Turning now to FIGS. 5A and 5B, one example of the sharing of clipped content between peers is shown. In the illustrated example, the user of the first peer device selects a “Send Page” button from the control buttons 64 to cause the transmission of a clip event to the server hosting the co-browsing session, as already discussed. The server may forward the event to the second peer device, which can use the clip event to construct a clipped page 76. The illustrated clipped page 76 includes the clipped content 74, wherein the clipped content is personalized to the first peer device and might not otherwise be available to the second peer device. Moreover, the illustrated clipped page does not include the non-clippable portion of the page 58, which includes sensitive content 68. As already noted, the first peer device could also share the clippable portion 66b either via the same clip event as the clipped content 74 on via a different clip event.
