Google Unveils AI-Powered Fake Call Detection

Google has introduced a new security feature called "Fake Call Detection" for Android devices, aimed at protecting users from AI-powered impersonation scams. The technology can identify suspicious calls in which fraudsters use artificial intelligence to clone the voices of family members, friends, or trusted contacts. Google says the feature is the first of its kind in the mobile industry and is designed to counter the growing threat of deepfake voice scams.

The system works through encrypted device verification using Rich Communication Services (RCS). When a legitimate call is placed, the caller's device sends a secure verification signal to the recipient's phone. If a caller claims to be someone from the user's contacts but the verification signal is absent, Android checks with the actual contact's device. If no call is being made, the recipient receives an alert warning of possible impersonation. The feature will roll out globally on Android 12 and above devices, starting with Pixel smartphones.
