Abstract: Routing server communications through a nearby mobile device. In some embodiments, the method may include establishing a direct communication channel between the first mobile device and the second mobile device, determining which of the first mobile device and the second mobile device is currently a more efficient mobile device that is able to communicate with a server device more efficiently, sending a first server query from the less efficient mobile device to the more efficient mobile device over the direct communication channel, forwarding the first server query from the more efficient mobile device to the server device over the Internet, receiving a first server response at the more efficient mobile device from the server device over the Internet, and forwarding the first server response from the more efficient mobile device to the less efficient mobile device over the direct communication channel.

Abstract: Employing beacon messages to restart an application on a mobile device. In some embodiments, a method may include subscribing, at the secondary mobile device, to a beacon publisher of the primary mobile device. The method may also include determining, based on historical location data, that the primary mobile device is likely within range of the secondary mobile device for beacon communication therebetween. The method may further include activating, at the primary mobile device, the beacon publisher. The method may also include publishing, at the primary mobile device, a beacon message configured to cause a secondary mobile application on the secondary mobile device to restart. The method may further include receiving, at the secondary mobile device, the beacon message. The method may also include, in response to receiving the beacon message, restarting, at the secondary mobile device, the secondary mobile application of the secondary mobile device.

Abstract: The disclosed computer-implemented method for detecting unauthorized use of an application may include (1) receiving, by the computing device, fingerprint data associated with a fingerprint, where the fingerprint data is received from the touchscreen, when a user interface of the application is displayed on the touchscreen, and in an absence of displaying a request for fingerprint data on the touchscreen, (2) comparing the received fingerprint data to a whitelist of authorized fingerprint data to determine a presence of a match, where the authorized fingerprint data indicates at least one fingerprint of at least one user that is authorized to access the application and (3) performing, when the received fingerprint data does not match the whitelist of authorized fingerprint data, a security action. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Methods and systems are provided for preventing the installation of malicious applications using system-level messages. One example method generally includes intercepting a request sent via an operating system of the computing device; determining the request is to access an application in a remote application repository; obtaining information associated with the application from the request; transmitting, over a network, the information to a security server; and receiving, over the network, a security recommendation for the application from the security server.

Abstract: A method for preventing malware is described. The method may include identifying a malicious application running on a first computing device, determining that the malicious application is installed on a second computing device based on the identifying, and performing a single operation including uninstalling the malicious application from the first computing device and the second computing device.
