Abstract: On a mobile communications device, visiting a link from a messaging application or web browser may result in an undesired action, such as visiting a phishing site, downloading malware, causing unwanted charges, using too much battery, or the device being exploited. In an implementation, a mobile application intercepts a request including an identifier associated with an action to be performed by another application on the device and evaluates the identifier to determine when the request should be permitted, blocked, or conditionally permitted. The client may use local data or make a request to a server to evaluate the identifier. In an implementation, server communications are optimized to minimize latency by caching evaluation results on the device, proactively priming the device's DNS cache, optimizing when DNS lookups are performed, and adapting evaluation policy based on factors such as the source of the request, and the currently active network connection.

Abstract: Embodiments are directed towards employing a plurality of object relationships to dynamically generate a hierarchical structure of dependent object relationships (“HSDOR”). Each object relationship may include a plurality of information, including, but not limited to, a consumer object, a provider object, a one or more direct values, a quantity of units consumed by the consumer object, or the like. Dependencies between the plurality of object relationships may be utilized to dynamically generate an HSDOR. In some embodiments, the HSDOR may be modified by resolving detected circularity relationships within the HSDOR and/or dynamically modifying object relationship dependencies affected by a new and/or modified object relationship. In some embodiments, the HSDOR may be utilized to iteratively determine a total value of an object as a function of total loaded values of object relationships from which the object depends.

Abstract: A system and method identifies mobile applications that can have an adverse effect on a mobile device or mobile network. In an implementation, a server monitors behavioral data relating to a mobile application and applies a model to determine if the application has an adverse effect or has the potential to cause an adverse effect on a mobile device or a network the mobile device may connect to. A mobile device may monitor behavioral data, apply a model to the data, and transmit a disposition to the server. The server may aggregate behavioral data or disposition information from multiple devices. The server may transmit or make available the disposition information to a subscriber through a web interface, API, email, or other mechanism. After identifying that an application may have an adverse effect, the server may enact corrective actions, such as generating device or network configuration data.
