The document discusses loyalty fraud and presents strategies to make human-device interactions more secure. It notes that loyalty fraud has significantly increased in recent years, with attacks tripling from 2016-2017. Current authentication methods are easily bypassed by fraudsters. The document proposes using passive biometrics and behavioral analysis with machine learning to provide continuous authentication, separate human and bot activity, and improve security while maintaining a seamless user experience. This new approach would help to detect uncaught fraud and reduce false positives seen in traditional rule-based solutions.
