User Authentication

Callsign has three platform capabilities:

Callsign web and mobile SDKs collect data intelligence including:

  • Behavioral biometrics data 
  • Device fingerprint identification 
  • Location analytics and
  • Threat indicators 

Using advanced AI and Machine Learning (ML) techniques, the Intelligence Engine collects, fuses and analyzes thousands of data points to provide ensembling and results management.  The intelligence engine generates a robust assessment of how likely it is that a user is who they claim to be.
