## Background
BACKGROUND
This disclosure relates generally to the field of removing sensitive information from a computer screen.
In a communication session such as a web conference or chat session, a participant may send a screen share of a graphical user interface (GUI) that is displayed on the participant's computer screen to other participants in the communication session. The screen share may inadvertently include confidential or personal information belonging to the sender. Therefore, sending the screen share to other parties, such as co-workers or customers, may be potentially embarrassing to the sender, or may represent a security risk. Sensitive information may also be inadvertently communicated to an unauthorized party if the unauthorized party views a user's computer screen. The user may have a browser open in their screen that contains, for example, their bank account or 401k information, and forget to close the browser before a meeting in which the screen is viewed by others. The screen may also be shared during a public presentation, resulting in a large number of outside parties viewing the sensitive information.

DETAILED DESCRIPTION
Embodiments of systems and methods for automatic screen censoring are provided, with exemplary embodiments being discussed below in detail.
Automatic screen censoring, or removal of sensitive information from a computer screen, may be implemented by automatically removing data that is designated as sensitive by a user from the user's screen. Automatic screen censoring may be applied in response to a trigger, including but not limited to a push of a button by the user, facial recognition software determining that an unauthorized person is viewing the user's screen, connection of the computer to a projection device, launching of a presentation, or sending of a screen share.
To censor a user's screen, object recognition technology, including but not limited to object maps, screen scraping, or optical character recognition (OCR), may be applied to the screen to determine the information present in the screen. The determined information may include both visible information and metadata. This determined information may then be compared to a set of user preferences to determine which portions of the screen comprise sensitive information to be censored. Granular censorship of information may be performed at the level of the contextual information determined by the object recognition technology; all or any part of the information in a particular application may be removed. Data located outside of but related to a shared region may also be used to determine whether to censor information located inside the shared region.
FIG. 1 illustrates an embodiment of a system 100 comprising automatic screen censoring. User screen 102 resides on user system 101, which may comprise any appropriate computing system. User screen 102 may comprise a GUI screen comprising various objects, including but not limited to application windows or icons. User system 101 further comprises a censoring module 103 in communication with object recognition module 104 and censoring preferences module 105. Object recognition module 104 and censoring preferences module 105 are shown for illustrative purposes only; in various embodiments, object recognition module 104 and censoring preferences module 105 may reside on user system 101, or on an external system in communication with user system 101 via a network.
The preferences stored in censoring preferences module 105 may designate various types of content as sensitive content that the user may wish to have removed from GUI screen 102. These preferences may be default values, or may be configured by the user or by an organization such as a user's employer. Censorable data may include any desired type of content that may be located in GUI screen 102, including but not limited to any text, GUI constructs, uniform resource identifier (URI), or images, and may relate to any information the user considers to be personal or sensitive, such as banking information, instant messaging conversations, or webpages that the user may view that the user does not wish to share with other parties. The preferences may designate strings that indicate censorable material, such as “Confidential”, “SSN”, “password” or “Social Security Number”. The user preferences may also comprise an image; if the object recognition module 104 detects an image in user screen 102 that is similar to the image designated in the preferences, the image may be censored from the user screen 102. Censorship preferences may be based on collaborative knowledge, such as social network relationships or corporate policy, and individual preference.
Censorship preferences may vary based on the identity of a person viewing the information, such as chat partner, viewer of a screen, or participant in a web conference. Different viewing schemes may be applied to different participants in a web conference. The user may define various viewing schemes in the preferences, such “View Everything” or “Show only Information Bob can see” scheme. In an example “Show only Information Bob can see” scheme, an application in the screen 102 may be minimized or blacked out if the content in the application is designated as confidential and doesn't have Bob's name on it. This may be integrated with a webcam employing facial recognition technology to automatically switch the viewing scheme if it is detected that Bob is viewing the screen 102.
FIG. 2 illustrates an embodiment of a method 200 for automatic screen censoring. FIG. 2 is discussed with reference to FIG. 1. In block 201, preferences regarding the types of information to be censored are determined and stored in censoring preferences module 105. In block 202, a censor trigger is received by the censoring module 103. The trigger may include but is not limited to a push of a button by the user, facial recognition software determining the viewing of the user's screen by another person, connection of the computer to a projection device, launching of a presentation, or sending of a screen share. In a screen sharing scenario, the user may select a region of screen to be shared; the region may include the entire screen or a portion of the screen. In block 203, information, including metadata, is identified regarding objects located in the user screen 102 by object recognition module 104. For a screen share, if less than the entire user screen 102 is to be shared, information regarding objects inside the share region, and information located outside of the share region that is relevant to the share region, may be identified. Object recognition module 104 may comprise object maps, which may traverse all objects in GUI screen 102 using any appropriate type of GUI element navigation technology, such as Rational Function Tester or Spy++. Text mining may be also employed by object recognition module 104 to determine strings that are present in the objects on user screen 102. In block 204, censoring module 103 determines sensitive content to be censored from the information identified in block 203. This determination is made by comparing the information gathered by object recognition module 104 with the censoring preferences stored in censoring preferences module 105. Some types of sensitive content may trigger a warning to the user, allowing the user to choose whether or not to censor the content based on the warning. The user's response to a warning may be added to the preferences stored in censoring preferences module 105 in some embodiments. The user may also be presented with a list of information gathered from the screen 102, allowing the user to select content to be censored. These selections may be stored in censoring preferences module 105 in some embodiments. Some types of content in GUI screen 102 are automatically removed without warning the user, or for certain types of triggers, such as a notification from a webcam that an unauthorized person is viewing the GUI screen 102, no warnings may be provided. In block 205, the sensitive content determined in block 204 is removed from screen 102. Removal may comprise minimizing or removal of a window or region containing the sensitive information, or black-out or replacement of the sensitive information, leaving the window visible.
FIG. 3 illustrates an embodiment of a user interface 300 for automatic screen censoring. User interface 300 may be displayed to the user as part of step 204 of FIG. 2, to allow the user to choose the information to be censored. User interface 300 shows user screen 301, which contains web browser window 302 (comprising URL 303 and SSN field 304), My Benefits window 305, and Notepad window 306. Information collected from windows 302, 305, and 306 by object recognition module 104 is displayed in available data window 307. The user may use checkboxes to select any of the information listed in available data window 307 to be censored by censoring module 103. The selected information may be added to the preferences stored in censoring preferences module 105. User interface 300 is shown for illustrative purposes only; various embodiments of automatic screen censoring may employ any appropriate user interface, or may apply the user preferences stored in censoring preferences module 105 without displaying a user interface.
FIG. 4 illustrates an embodiment of a censored screen 400. In censored screen 400, URL 403 is visible in browser window 402, but SSN field 404 has been cleared. Also, information has been removed from windows 405 and 406. Censored screen 400 is shown for illustrative purposes only; a censored screen may have any amount or type of content removed in any appropriate manner, including minimizing, replacement, or blacking out.
FIG. 5 illustrates an embodiment of a user interface 500 for setting a user's censoring preferences. User interface 500 shows various types of information 501 that may be present in a user screen, such as title string, author, images, or text. The user may edit the information 501 and check or uncheck any of the boxes associated with information 501 to designate which information will be censored. The user's preferences may then be stored in censoring preferences module 105 by clicking the save button 502. User interface 500 is shown for illustrative purposes only; the user preferences to be stored in censoring preferences module 105 may be determined in any appropriate manner.
FIG. 6 illustrates an example of a computer 600 which may be utilized by exemplary embodiments of systems and methods for automatic screen censoring as embodied in software. Various operations discussed above may utilize the capabilities of the computer 600. One or more of the capabilities of the computer 600 may be incorporated in any element, module, application, and/or component discussed herein.
The computer 600 includes, but is not limited to, PCs, workstations, laptops, PDAs, palm devices, servers, storages, and the like. Generally, in terms of hardware architecture, the computer 600 may include one or more processors 610, memory 620, and one or more input and/or output (I/O) devices 670 that are communicatively coupled via a local interface (not shown). The local interface can be, for example but not limited to, one or more buses or other wired or wireless connections, as is known in the art. The local interface may have additional elements, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.
The processor 610 is a hardware device for executing software that can be stored in the memory 620. The processor 610 can be virtually any custom made or commercially available processor, a central processing unit (CPU), a digital signal processor (DSP), or an auxiliary processor among several processors associated with the computer 600, and the processor 610 may be a semiconductor based microprocessor (in the form of a microchip) or a macroprocessor.
The memory 620 can include any one or combination of volatile memory elements (e.g., random access memory (RAM), such as dynamic random access memory (DRAM), static random access memory (SRAM), etc.) and nonvolatile memory elements (e.g., ROM, erasable programmable read only memory (EPROM), electronically erasable programmable read only memory (EEPROM), programmable read only memory (PROM), tape, compact disc read only memory (CD-ROM), disk, diskette, cartridge, cassette or the like, etc.). Moreover, the memory 620 may incorporate electronic, magnetic, optical, and/or other types of storage media. Note that the memory 620 can have a distributed architecture, where various components are situated remote from one another, but can be accessed by the processor 610.
The software in the memory 620 may include one or more separate programs, each of which comprises an ordered listing of executable instructions for implementing logical functions. The software in the memory 620 includes a suitable operating system (O/S) 650, compiler 640, source code 630, and one or more applications 660 in accordance with exemplary embodiments. As illustrated, the application 660 comprises numerous functional components for implementing the features and operations of the exemplary embodiments. The application 660 of the computer 600 may represent various applications, computational units, logic, functional units, processes, operations, virtual entities, and/or modules in accordance with exemplary embodiments, but the application 660 is not meant to be a limitation.

When a source program, then the program is usually translated via a compiler (such as the compiler 640), assembler, interpreter, or the like, which may or may not be included within the memory 620, so as to operate properly in connection with the O/S 650. Furthermore, the application 660 can be written as an object oriented programming language, which has classes of data and methods, or a procedure programming language, which has routines, subroutines, and/or functions, for example but not limited to, C, C++, C#, Pascal, BASIC, API calls, HTML, XHTML, XML, ASP scripts, FORTRAN, COBOL, Perl, Java, ADA, .NET, and the like.
The I/O devices 670 may include input devices such as, for example but not limited to, a mouse, keyboard, scanner, microphone, camera, etc. Furthermore, the I/O devices 670 may also include output devices, for example but not limited to a printer, display, etc. Finally, the I/O devices 670 may further include devices that communicate both inputs and outputs, for instance but not limited to, a NIC or modulator/demodulator (for accessing remote devices, other files, devices, systems, or a network), a radio frequency (RF) or other transceiver, a telephonic interface, a bridge, a router, etc. The I/O devices 670 also include components for communicating over various networks, such as the Internet or intranet.
If the computer 600 is a PC, workstation, intelligent device or the like, the software in the memory 620 may further include a basic input output system (BIOS) (omitted for simplicity). The BIOS is a set of essential software routines that initialize and test hardware at startup, start the O/S 650, and support the transfer of data among the hardware devices. The BIOS is stored in some type of read-only-memory, such as ROM, PROM, EPROM, EEPROM or the like, so that the BIOS can be executed when the computer 600 is activated.
When the computer 600 is in operation, the processor 610 is configured to execute software stored within the memory 620, to communicate data to and from the memory 620, and to generally control operations of the computer 600 pursuant to the software. The application 660 and the O/S 650 are read, in whole or in part, by the processor 610, perhaps buffered within the processor 610, and then executed.
When the application 660 is implemented in software it should be noted that the application 660 can be stored on virtually any computer readable medium for use by or in connection with any computer related system or method. In the context of this document, a computer readable medium may be an electronic, magnetic, optical, or other physical device or means that can contain or store a computer program for use by or in connection with a computer related system or method.
