Because the AI processing happens entirely on your local hardware rather than a remote cloud server, your private conversation data remains completely secure and hidden from outside parties while it screens for fraud. 

Apple's security tools handle fraud through these primary features:

1. Call Screening ("Ask Reason for Calling")

Instead of intercepting calls in real time, Apple uses an AI-powered automated screener for unknown numbers. If an unknown number calls, your iPhone can answer for you, ask the caller who they are and why they are calling, and show you a live text transcript of their response before you ever pick up. If it reads like a scam, you can just tap "End Call".

  • How to enable it: Go to Settings > Apps > Phone > Screen Unknown Callers and select Ask Reason for Calling.

2. Impersonation Risk Detection

Introduced in iOS 27, this on-device feature protects you after a scammer has already convinced you to do something dangerous (like transferring money from your banking app). It securely analyzes your interaction patterns, timing, and phone usage to determine if you are actively being pressured or coached by a scammer during a sensitive transaction. It then prompts your bank's app to block the transfer or display an identity check.

  • How to enable it: Go to Settings > Privacy & Security > Impersonation Risk Detection and turn on Share with App Developers.

3. Live Voicemail

Similar to call screening, if you let an unknown call go to voicemail, your screen will show a live transcript of what the caller is saying as they say it. You can choose to interrupt and pick up if you realize it's a legitimate call.

  • How to enable it: Go to Settings > Apps > Phone > Live Voicemail and toggle it On.
