Patent Issued for Mediating Resource Access Based on a Physical Location of a Mobile Device

August 7, 2014



By a News Reporter-Staff News Editor at Computer Weekly News -- A patent by the inventors Mazzaferri, Richard (Mooney Mooney, AU); Duursma, Martin (West Pennant Hills, AU); Hackett, Donovan (Marsfield, AU); Laborczfalvi, Lee (Wollstonecraft, AU), filed on October 6, 2011, was published online on July 22, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8789144 is assigned to Citrix Systems, Inc. (Fort Lauderdale, FL).

The following quote was obtained by the news editors from the background information supplied by the inventors: "The proliferation of mobile devices equipped to execute remote applications and access remote resources from any location and over any network greatly increases the need to control whether to send remote content to a mobile device. Using a mobile device to display remotely executing applications that can potentially access and display sensitive information can pose a security risk. One way to mitigate this risk can include only providing the mobile device with access to those resources deemed safe for viewing in a public location. Determining whether a mobile device is located within a public location can include determining what type of network the mobile device uses to access the remote application and remote resources.

"Restricting application and resource access in this way can pose problems when a user accesses a resource or application using a secure network but in an unsecure physical location. For example, the status of a network as secure might not be indicative of the actual or underlying conditions, such that in reality access rights should not be provided or granted to a particular client device."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosure. The summary is not an extensive overview of the disclosure. It is neither intended to identify key or critical elements of the disclosure nor to delineate the scope of the disclosure. The following summary merely presents some concepts of the disclosure in a simplified form as a prelude to the description below.

"Aspects of the disclosure are directed to methods, apparatuses, computer-readable media, and systems for mediating access to one or more resources.

"Aspects of the disclosure are directed to mitigating security problems associated with displaying sensitive information on a device, such as a mobile device, when that device is physically located in an unsecure location.

"Aspects of the disclosure are directed to mediating access to applications and resources based on a device's (e.g., a mobile device's) physical location. In some embodiments, information associated with a device's, e.g., a client device's, current location may be received. One or more other devices, such as one or more servers, may determine whether the client device is located in an area that is predetermined to be a safe area. Responsive to determining that the information indicates that the client device is located in an area that is predetermined to be a safe area, the server may cause the client device to be provided with access to content, such as remote content comprising remote application output. In some embodiments, the server may host the remote content. In some embodiments, the output may comprise draw commands and images generated by a remote application. In some embodiments, the remote content may comprise one or more remote files.

"In some embodiments, a determination may be made that a client device has changed location. For example, a determination may be made that the client device has moved from a safe area to an area that is either an unsafe area or not a safe area. Responsive to determining that the client device has moved from a safe area to an area that is either an unsafe area or not a safe area, access to a resource may be partially or completely restricted. In some embodiments, access to a resource may be based at least in part on one or more conditions, such as a determined location of a client device.

"Aspects of the disclosure are directed to causing one or more applications to be displayed on a device, such as a mobile device. The applications may receive input from a touch screen. The applications may be displayed within the context of an operating system configured to receive input via a touch screen. In some embodiments, one or more applications may be remotely-generated.

"In some embodiments, a focus event may be intercepted or a notification of a focus event may be received and sent to a device, such as a mobile computing device. The focus event may be associated with a remote application executing on a remote computer. The event notification may be transmitted from the remote computer to the device. In some embodiments, the remote application executing on the remote computer may be displayed on the device. Upon receiving the event notification, the device may alter the display of the remote application.

"In some instances, when a particular control or edit field within a remote application receives focus, a virtual keyboard may be displayed, e.g., on a display of a device, such as a mobile device. When that control or edit field loses focus, the virtual keyboard might be hidden. In some embodiments, when a virtual keyboard is displayed in response to a control or edit field receiving focus, the application may be panned (e.g., scrolled upwards or downwards) to prevent the virtual keyboard from covering the control or edit field.

"In some embodiments, a zoom level associated with a section of an application may be adjusted. The zoom level may be adjusted responsive to determining that a control or edit field in that section of the application has focus. The zoom level adjustment may include zooming in or zooming out. The control may comprise one or more of a list box, a combo box, or other similar control. Zooming in on the section of the application housing the control may be accomplished using a native zoom function provided by an operating system executing on the device, or a custom zooming function provided by a client executing on the device, e.g. CITRIX RECEIVER/ICA CLIENT. In some embodiments, the methods and systems described herein may permit using a local slider function in lieu of a slider control that may be provided within the application.

"When a user is displaying a remote application, or desktop, the user may intelligently zoom or pan on the title bar, scroll bar, window edges or other features of a window associated with the remote application. Thus, rather than trying to manually scale these features, the user may interact with the remote application in substantially the same way that the user would interact with an application modified to execute on the device and receive primarily touch screen input. For example, upon a user placing focus on a section of the remote application for a predetermined period of time (e.g. 0.3 seconds), the system may take advantage of local auto-zoom controls to auto-zoom to the section of the remote application that received focus. Auto-zooming may include a verification of the coordinates of the section of the remote application and then zooming to that section. In some embodiments, zooming may include showing a zooming bubble on the device when a user touches a control within the remote application.

"Aspects of the disclosure are directed to providing a native user experience for users accessing remote applications through an application executing on a device, such as a mobile device. The application executing on the device, in some embodiments, may include CITRIX RECEIVER published by CITRIX SYSTEMS. In other embodiments, the device may include an IPHONE or IPAD.

"Aspects of the disclosure are directed to mitigating display problems created by trying to display a remote application on a device, such as a mobile device. In some embodiments, one or more existing and/or displayed applications may be altered to facilitate the display of the remote application so that those facilitating applications properly display the remote application. For example, FIG. 11 illustrates an example of a properly displayed remote application where the text control of focus 1108 may be scrolled up, located, and/or sized automatically so that the a virtual keyboard 1114 does not overlap the text control and so that a user can view data as it is inputted into the text control 1108 using the keyboard 1114. In FIG. 11, the keyboard may automatically pop up or launch instead of being manually launched."
