Google announced on Tuesday the official launch of its fake call detection feature in the Android system, using innovative "end-to-end digital handshake" technology to combat the growing threat of AI deepfake voice impersonation scams at their source. The feature will roll out globally starting in June 2026 for Phone by Google devices running Android 12 and above, initially launching on Pixel devices.

Currently, scammers are accelerating the use of AI large model technology to accurately clone the voices of authoritative figures, employers, or family members, and forge credible incoming calls for financial fraud. In response to this new security threat, Google's fake call detection feature adopts a default-on mechanism that runs silently in the background.

When both parties use Google's phone service, the calling device automatically sends a silent confirmation signal to the receiving device to verify its authenticity; if an AI impersonation is detected, the system will immediately send a ping request to the contact's real device. If it confirms that the device did not make the call, the system will pop up a security warning on the screen to prompt the user to hang up.

Notably, this anti-fraud network is built based on the Rich Communication Services (RCS) standard and has the potential to be open to other application ecosystems and third-party hardware manufacturers. As part of the same update, Google also upgraded the entire outfit search function of "Smart Selection Search" and launched an AI-based virtual try-on feature called "Closet" in Google Photos in the US, India, and Pakistan.

This update shows that as the threshold for misuse of generative AI decreases, leading tech giants are shifting their defense focus from traditional blacklisting to real-time identity verification based on underlying protocols. Edge-side security mechanisms are rapidly becoming a core barrier in the smartphone ecosystem.
