In response to the increasing threat of voice cloning and call spoofing scams, Google has launched a new feature called 'Fake Call Detection' for Android smartphones. This feature, which will be available on devices running Android 12 or later, aims to verify the authenticity of incoming calls before users answer them. The system operates through a digital 'handshake' that exchanges verification signals between the caller's and receiver's phones. If a suspicious call is detected, the system sends a message to the caller's phone, and if the caller denies making the call, the receiver is alerted to end the call. This feature utilizes Rich Communication Services (RCS) technology, ensuring enhanced security and privacy through end-to-end encryption. With scams involving voice cloning and number spoofing leading to significant financial losses worldwide, Google's new system represents a crucial step in mobile security, although it requires both parties to use the supported system for effective protection.
