  • Managing information associated with network resources
    Patent number: 9037696
    Abstract: Systems, methods and interfaces for the selective management of information collected by a browser are provided. The browser obtains a network resource, such as a Web page, from a content provider, and collects information associated with the display and interaction with the content by a user. The browser presents, among other controls, a graphical icon that is representative of an integrated command to remove information collected while accessing a first network resource and to cause the browser application to access a second accessed network resource. Upon receipt of an input corresponding to the selection of the graphical icon, the browser deletes information collected while accessing the first network resource and accesses the second network resource.

  • VIEWER-BASED DEVICE CONTROL
    Publication number: 20150116212
    Abstract: A computing device can monitor the gaze direction of people around the device to determine whether any unintended viewers are viewing content displayed on the device. A user can activate a privacy mode of the device, such that when an unintended viewer is detected the device can take an appropriate action. In some cases the device can notify the primary user of the device using audible, visual, or tactile alerts. In other cases, the device can modify the display of content such that the unintended viewer is unable to decipher or view the content, or is otherwise notified of the detection.
