  • Patent number: 9912847
    Abstract: A user can capture an image of an object, using a computing device, to obtain information about that object. If a specular highlight (or other saturated region) is detected, the device can attempt to determine a location of a light source associated with the highlight. The device can then provide instructions as to a direction to move in order to reduce the presence of the specular highlight in subsequent images. Multiple images of the object can be captured and analyzed to generate a three-dimensional reconstruction of the environment, whereby a position of the light source can be determined. In other embodiments, movement of the specular reflections in response to movement of the device is used to determine a direction of the light source. In other embodiments, an image of the user is captured to determine the position of the light source based on shadows or reflections on the user.

  • Patent number: 8850185
    Abstract: Technologies are described herein for post attack man-in-the-middle detection. A first computer receives and stores public key certificates when connections are established. The first computer also uploads the stored public key certificates associated with a domain to a second computer each time a connection is established with the domain. The second computer receives the public key certificates from the first computer. The second computer then determines whether any of the public key certificates provided by the first computer are fraudulent certificates by comparing the received certificates to known valid certificates. If the second computer determines that the first computer has received one or more fraudulent certificates, the second computer may cause action to be taken with regard to the fraudulent certificates.

  • Publication number: 20140189499
    Abstract: A user device receives a content item and a script associated with the content item. The user device stores an obfuscated version of the content item and an associated style sheet in memory. The user device dynamically updates the style sheet stored in the memory using the script to remove the obfuscation from the obfuscated version of the content item when the content item is presented in a web browser running on the user device.

  • Publication number: 20130080968
    Abstract: Some implementations include displaying media content items on a home screen of a computing device. A display order for a list of media content items may be determined based, at least in part, on a predicted likelihood that an individual one of the plurality of media content items will be selected. A home screen of a user interface may be displayed, according to the determined display order, with a list of a plurality of media content items that are available to the computing device.
