  • Publication number: 20160294942
    Abstract: Mobile devices or other client devices generally support applications that provide content to users. Application-related data transfer represents a significant portion of client device bandwidth usage. As client devices are frequently within the range of gateways (e.g., WiFi routers), the gateways may assist with application data transfer. Through application-sensitive and proactive data transfer strategies, the gateways may improve user experience and power consumption on the client devices. Disclosed are systems and methods for synchronizing application content between client devices and application servers through gateways.

  • Patent number: 9439077
    Abstract: Disclosed is a method for malicious activity detection in a mobile station of a particular model. In the method, generic malicious behavior patterns are received from a network-based malicious behavior profiling system. Mobile-station-model-specific-behavior-analysis algorithms are generated in the mobile station based on the generic malicious behavior patterns. Mobile station operations may be observed to generate a mobile station activity observation. The mobile station activity observation may be analyzed using the mobile-station-model-specific-behavior-analysis algorithms to generate an activity analysis. Malicious activity may be detected based on the activity analysis.

  • Publication number: 20160248766
    Abstract: A gateway device may control access to content based, at least in part, on an audience that will consume the content. In relation to a request for content to be delivered to a media output device, the gateway device may obtain biometric data from one or more trait capture devices having a physical relation to the media output device. The gateway can determine the potential audience of the content and enforce content restrictions based on the audience. The content restrictions may be based on one or more content attributes about the content and one or more audience traits about the audience. The gateway may use thresholds associated with the audience trait to determine whether the content attribute is appropriate for the audience. The threshold or a combination of thresholds may provide for granular control of access to content.
