## Title
Public BOT management in private networks

## Abstract

A system for managing the use of BOTs by computer network users, the system including a gateway-to-BOT communications manager configured to relay communications to a BOT on behalf of a computer user in a manner that prevents the BOT from associating the communications with the computer user, and a gateway-to-user communications manager configured to relay the communications from the computer user to the gateway-to-BOT communications manager, and relay to the computer user communications received from the gateway-to-BOT communications manager that originate from the BOT.

## Background
FIELD OF THE INVENTION
The present invention relates to computer network management in general, and more particularly to managing the use of public BOTs by private computer network users.
BACKGROUND OF THE INVENTION
Company computer networks typically allow company computer users to access non-company networks, while enforcing strict security measures to prevent unauthorized access to company information from such non-company networks. However, maintaining such security measures is becoming increasingly challenging due to the increasing appetite of company employees for emerging information resources available from public information providers.
One method for accessing public information resources involves employing instant messaging (IM) robots (BOTs) that act as virtual users for supplying information to employees who subscribe to receive information from such resources. An employee may subscribe to receive presence information from a BOT by adding the BOT to the employee's IM software contact list, and thereafter may open a chat session with the BOT to query the BOT for information such as stock prices, language translations, weather reports, etc. In doing so, the employee typically provides his/her network address to the BOT. Unfortunately, public BOTs are often configured to store the addresses of users that use BOTs, thereafter initiating unwanted chat sessions with the users. Furthermore, where companies employ a centralized collaboration server(s) that acts as a gateway between employees and public BOTs, the server maintains a separate subscription for each employee that is subscribed the same BOT, placing a significant load on the collaboration server(s).

Reference is now made to FIG. 1, which is a simplified conceptual illustration of a system for managing the use of public BOTs by private computer network users, constructed and operative in accordance with an embodiment of the invention. In the system of FIG. 1 a computer user at a computer 100 (now referred to as user 100) in a first computer network 102, such as a company private computer network, notifies a gateway 104 that user 100 wishes to receive presence information regarding a public BOT 106 that is accessible at a computer server 108 via a second computer network 110, such as the Internet. User 100 may provide the notification to gateway 104 using any conventional technique, such as by adding BOT 106 to an IM contact list 112 that is associated with user 100, whereupon the addition is made known to gateway 104.
Gateway 104 sends a subscription request on behalf of user 100 to server 108 requesting that a subscription be established for presence information regarding BOT 106. Preferably, gateway 104 maintains a list 114 of permitted BOTs, and only sends the subscription request if BOT 106 is found within list 114. Preferably, the subscription request is sent in a manner that prevents BOT 106 from associating the subscription request with user 100, such as where the subscription request does not include information identifying user 100. In one embodiment gateway 104 generates fictitious user information representing a fictitious user other than user 100 and who is not known to gateway 104, and indicates in the subscription request that the subscription is for the fictitious user. In one embodiment, rather than sending a subscription requests in response to a user request for BOT presence information, gateway 104 sends a subscription requests for each BOT in list 114 independent from a user request for BOT presence information, such as at startup of gateway 104.
Gateway 104 preferably maintains a list 116 of users in network 102 who have asked to receive presence information regarding public BOTs. Thus, when gateway 104 receives presence information from server 108 regarding BOT 106, gateway 104 preferably forwards the presence information to user 100 and any other users in list 116 who have asked to receive presence information regarding BOT 106.
When user 100 notifies gateway 104 that user 100 wishes to communicate with BOT 106, gateway 104 preferably establishes a communications session 118, such as a chat session, with user 100, as well as a separate communications session 120 with BOT 106, such as via server 108, in a manner that prevents GOT 106 from associating communications session 120 with user 100, such as described above. Communications received from user 100 by gateway 104 via session 118 are forwarded to BOT 106 via session 120 without information identifying user 100, and communications received from BOT 106 by gateway 104 via session 120 are then forwarded to user 100 via session 118. Where communications with BOT 106 require a separate subscription with BOT 106 for each communications session between a computer user and BOT 106 via gateway 104, gateway 104 preferably sends a subscription request to server 108 for the communications session with BOT 106 in a manner that prevents BOT 106 from associating the request with user 100, such as described above. Gateway 104 associates the subscription with the communications session, and preferably cancels the subscription when the communications session is terminated.
Reference is now made to FIG. 2, which is a simplified flowchart illustration of an exemplary method of operation of the system of FIG. 1, operative in accordance with an embodiment of the invention. In the method of FIG. 2 a computer user in a first computer network asks to receive presence information regarding a public BOT that is accessible via a second computer network. A subscription is established for presence information regarding the BOT, where the subscription does not identify the user, but instead identifies a fictitious user. Published presence information regarding the BOT is forwarded to the user. When the user wishes to communicate with the BOT, a first communications session is established with the BOT, and a second communications session is established with the user. Communications received from the user via the second communications session are forwarded to the BOT via the first communications session, and communications received from the BOT via the first communications session are forwarded to the user via the second communications session.
Reference is now made to FIG. 3, which is a simplified block diagram of a gateway in a system for managing the use of public BOTs by private computer network users, constructed and operative in accordance with an embodiment of the invention. In FIG. 3 a gateway 300, such as may be employed as gateway 104 of FIG. 1, includes a gateway-to-user communications manager 302 for managing communications with computer users, such as for receiving requests for presence information regarding public BOTs, forwarding such presence information to computer users, and for conveying communications to and from computer users via gateway-to-user communications sessions such as communications session 118 of FIG. 1. A gateway-to-BOT communications manager 304 is shown for managing communications with and about BOTs, such as for forwarding requests for presence information regarding public BOTs, and for conveying communications to and from BOTs or BOT servers via gateway-to-BOT communications sessions such as communications session 120 of FIG. 1. A user list manager 306 is shown for maintaining a list of real and fictitious computer users that are to receive BOT presence information and that wish to communicate with BOTs. A BOT list manager 308 is shown for maintaining a list of permitted BOTs about which computer users served by gateway 300 may receive information and with which those computer users may communicate via gateway 300.
It will be appreciated that any aspect of the invention described hereinabove may be implemented as a computer program product embodied in a computer-readable medium, such as in the form of computer program instructions stored on magnetic or optical storage media or embedded within computer hardware, and may be executed by or otherwise be made accessible to a computer.
It will be appreciated that the invention provides improvements over the prior art in that it allows computer users in a private computer network to communicate anonymously with public BOTs that are accessible via public computer networks. Thus, a BOT that attempts to initiate a chat sessions with a previous user of the BOT with not be able to communicate directly with the user, as the BOT never receives information identifying the user, and any such attempts may be intercepted by an intermediate gateway and ignored. Furthermore, the invention does not require that the intermediate gateway maintain separate subscriptions for each private computer network user who wishes to receive presence information regarding the BOT.
Referring now to FIG. 4, block diagram 400 illustrates an exemplary hardware implementation of a computing system in accordance with which one or more components/methodologies of the invention (e.g., components/methodologies described in the context of FIGS. 1-3) may be implemented, according to an embodiment of the invention.
As shown, the techniques for controlling access to at least one resource may be implemented in accordance with a processor 410, a memory 412, I/O devices 414, and a network interface 416, coupled via a computer bus 418 or alternate connection arrangement.
It is to be appreciated that the term “processor” as used herein is intended to include any processing device, such as, for example, one that includes a CPU (central processing unit) and/or other processing circuitry. It is also to be understood that the term “processor” may refer to more than one processing device and that various elements associated with a processing device may be shared by other processing devices.
The term “memory” as used herein is intended to include memory associated with a processor or CPU, such as, for example, RAM, ROM, a fixed memory device (e.g., hard drive), a removable memory device (e.g., diskette), flash memory, etc. Such memory may be considered a computer readable storage medium.
In addition, the phrase “input/output devices” or “I/O devices” as used herein is intended to include, for example, one or more input devices (e.g., keyboard, mouse, scanner, etc.) for entering data to the processing unit, and/or one or more output devices (e.g., speaker, display, printer, etc.) for presenting results associated with the processing unit.
