Abstract: A method of transmitting data to a virtual group consisting of multiple user devices. A plurality of network-connected user devices are grouped together into a virtual group using their International Mobile Subscriber Identification (IMSI) or Mobile Station International Subscriber Directory Number (MSISDN) contained within a SIM card residing within each user device. An application programming interface (API) and a single identification are established for the virtual group and are exposed to an application server. Data packets sent to the virtual group via a communications protocol from the application server are intercepted and directed to each user device within the virtual group. The plurality of user devices within the virtual group can simultaneously receive the data stream.

Abstract: The invention is a method of detecting malicious behavior of a network participant. Specific usage values observable at a network connectivity layer are defined. These usage values can be size of data transferred, quantity of data bursts, a quantity of IP address destinations, a network protocol being used, and/or a length of an encryption key. The invention measures the usage values for the network participant across multiple networks over a predetermined period of time and creates a statistical digital dossier representative of patterns of the measured usage values for the network participant. The invention monitors the behavior of the network participant by measuring current usage values. The current usage values are compared against the statistical digital dossier and, if a deviation beyond a predefined tolerance is detected, an alert signal is issued.
