Apple announced Trust Insights, a new on-device anti-fraud feature in iOS 27 that analyzes user behavior patterns to detect scams without reading personal content like messages or photos. This feature enhances user security against phone scams while maintaining strong privacy by processing data entirely on-device and only sending a single anonymized output to servers. Trust Insights uses device sensor data and contextual analysis to identify suspicious behavior like being guided by a scammer to transfer money or change accounts; it can trigger warnings, delays, or extra authentication before transactions.
Background
On-device anti-fraud detection uses local AI analysis to catch suspicious activities without sending raw data to the cloud, preserving privacy. Cooling periods are security windows after changes (like binding a new device) that temporarily lock settings to prevent scammers from disabling protections.
