Abstract: Described is neuromorphic system for authorized user detection. The system includes a client device comprising a plurality of sensor types providing streaming sensor data and one or more processors. The one or more processors include an input processing component and an output processing component. A neuromorphic electronic component is embedded in or on the client device for continuously monitoring the streaming sensor data and generating out-spikes based on the streaming sensor data. Further, the output processing component classifies the streaming sensor data based on the out-spikes to detect an anomalous signal and classify the anomalous signal.

Abstract: An asynchronous pulse domain to synchronous digital domain converter for converting pulse domain signals in an input asynchronous pulse domain data stream to synchronous digital domain signals in a data output stream. The converter comprises a plurality of counters arranged in a ring configuration with only one counter in the ring being responsive at any given time to positive and negative going pulses in the input asynchronous pulse domain data stream, each counter, when so responsive, counting a number of time units between either (i) a positive going pulse and an immediately following negative going pulse or (ii) a negative going pulse and an immediately following positive going pulse, the counts of the counters when so responsive being synchronously converted to synchronous digital domain signals in the data output stream. The disclosed asynchronous pulse domain to synchronous digital domain converter can be used with spike domain signals if desired.

Abstract: Described is a low power system for mobile devices that provides continuous, behavior-based security validation of mobile device applications using neuromorphic hardware. A mobile device comprises a neuromorphic hardware component that runs on the mobile device for continuously monitoring time series related to individual mobile device application behaviors, detecting and classifying pattern anomalies associated with a known malware threat in the time series related to individual mobile device application behaviors, and generating an alert related to the known malware threat. The mobile device identifies pattern anomalies in dependency relationships of mobile device inter-application and intra-applications communications, detects pattern anomalies associated with new malware threats, and isolates a mobile device application having a risk of malware above a predetermined threshold relative to a risk management policy.
