Google is launching a new fake call detection feature for Android devices to protect users from AI-powered impersonation scams by verifying the legitimacy of incoming calls in real time.

Key Points

• The feature uses end-to-end encrypted RCS technology to send a silent confirmation signal between devices during a call.
• If a call lacks the required verification signal, the system pings the contact's device to confirm if they are actually initiating a call.
• Users receive an on-screen warning to hang up immediately if the system detects a potential impersonation attempt.
• The tool requires the Phone by Google app, Google Messages, and Google Contacts to be installed on both devices.
• Rolling out this month, the feature supports Android 12 and newer devices, starting with Google Pixel phones.
• Google designed the technology to be potentially adoptable by other device manufacturers and third-party applications.

Why it Matters

This security update addresses the rising risk of sophisticated deepfake scams that leverage artificial intelligence to deceive mobile users. By integrating verification directly into the Android ecosystem, Google provides a scalable defense mechanism that could significantly reduce successful social engineering attacks.
