  • BIOMETRIC THREAT INTELLIGENCE PROCESSING FOR BLOCKCHAINS
    Publication number: 20190327079
    Abstract: An example operation may include one or more of detecting a suspected biometric authentication incident, submitting a first blockchain transaction including a first report to a blockchain network, submitting a second blockchain transaction including a second report to the blockchain network, and taking an action, by one or more blockchain nodes, in response to determining one or more of the first and second reports are relevant to the one or more blockchain nodes. The first report includes public and private data corresponding to the suspected biometric authentication incident, and the second report includes one or more of a root cause and mitigation steps for the incident.

  • Audio-based event interaction analytics
    Patent number: 10043517
    Abstract: In an approach for audio based event analytics, a processor receives a recording of audio from an event. A processor collects information about the event and a list of participants. A processor segments the recording into, at least, a plurality of utterances. A processor analyzes the segmented recording. A processor summarizes the recording based on the segmentation and the analysis. A processor generates insights about interactions patterns of the event based on the segmentation and the analysis.
