  • Publication number: 20250117485
    Abstract: An artificial intelligence (AI)-based system for detecting malware in endpoint devices using a multi-source data fusion and method thereof are disclosed. The AI-based system collects at least one of: endpoint visibility data, publicly available information, and sandbox analysis data using the multi-source data fusion. By using the collected data, the AI-based system generates one or more numerical embeddings for at least one of: one or more files and one or more applications of each endpoint device using one or more AI models. The AI-based system is configured with the one or more AI models to generate one or more dynamic directed graphs based on the generated one or more numerical embeddings to compute a maliciousness risk score. The maliciousness risk score of at least one of the: one or more files and one or more applications is used for detecting the malware in the one or more endpoint devices.

  • Publication number: 20250023894
    Abstract: A system for detecting anomalous network patterns based on analyzing network traffic data and method thereof are disclosed. The system comprises a flow aggregator subsystem, a flow feature generation subsystem, an anomaly detection subsystem, a dynamic score subsystem, and a calibration subsystem. The system is configured to receive the network traffic data from one or more network endpoints for aggregating the network traffic data into network flow data. The system is configured to generate one or more flow features for each packet associated with the aggregated network traffic data based on a rolling window-based analysis of the one or more attributes. The system is configured to analyze the one or more flow features by utilizing one or more deep-learning models to detect the one or more anomalous network patterns.

  • Patent number: 9462440
    Abstract: Techniques are provided for delivering content to mobile communication devices related to interactions of members with a user community. The method involves detecting a communication session involving a mobile communication device; determining one or more context parameters associated with the communication session; and delivering content related to the context parameters to one or more mobile communication devices. Data is stored at a central computing entity that indicates association or membership of a plurality of mobile communication device users in a user community. The central computing entity detects when an action is taken by one mobile device user that is a member of the user community, and sends a notification to members of the social circle based on the detected action. These techniques allow individuals who are involved in a user community to maintain their interaction with the user community using their mobile communication devices.

  • Patent number: 8233894
    Abstract: Techniques are provided that extend the capabilities of mobile phone devices to automatically assign media content items to “contacts” list entries. Thus, if a mobile device user indicates the desire to purchase a media content item to be assigned to or associated with another mobile device user (e.g., an entry in a contacts list), the experience of acquiring that media content item and making the assignment can be seamless reducing the number of tedious manual steps to accomplish that task.

  • Patent number: 7751848
    Abstract: A system is provided that enables the delivery of multiple concurrent mobile applications to a mobile communication device. A concurrency application server interfaces to a mobile switching center to obtain call parameters in order to determine a context of a mobile device call. The concurrency application server also interfaces with equipment in a data network. A concurrency application plug-in resides on the mobile communication device to enable the device to switch between two or more active mobile applications on the device, either under user control or automatically. The concurrency application server determines a context of a call or other activity engaged by the mobile device user to determine what additional content to deliver for display on the mobile device, or what other mobile applications to invoke for the mobile device.
