Your Android cell phone can now alert you if a call uses an AI-generated voice

This feature will be enabled by default and will operate automatically in the background.

Its operation can be understood as a kind of “digital handshake” between devices. When a contact makes a call and both people use Phone by Google the sender’s device sends a silent confirmation signal in real time to the receiving device to verify that the call is legitimate and that it is indeed originating from that contact’s equipment.

This process uses technology Rich Communication Services (RCS) with end-to-end encryption, ensuring that verification is done completely privately.

If a scammer tries to impersonate one of your contacts, that initial confirmation signal will be absent.

In that case, the receiving device will immediately detect the anomaly and consult the contact’s actual device for further verification. If the legitimate device responds that it is not making a call at that moment, Android will display a warning on the screen recommending cutting off communication immediately.

This preventive alert allows users to identify and prevent spoofing attempts using deepfakes and call spoofing in real time.

The feature can be disabled at any time from the app settings Phone by Google.

Google will begin the global rollout of Fake Call Detection this month for Android 12 or higher devices running Phone by Googlestarting with Pixel devices.

At the moment, Phone by Google is now the default phone app on most Android devices. Devices using a different app can download Phone by Google from the Google Play Store and set it as the default app to access this protection.

Google notes that security should not be limited to a single type of device or application. Therefore, the company seeks to raise protection standards throughout the industry and extend these capabilities to as many users as possible.

With this objective, the function was developed on Rich Communication Services (RCS)an open standard that allows other device manufacturers and application developers to adopt this technology in the future.

Google already has a long-term track record in developing technologies aimed at combating digital fraud and identity theft:

• Scam Detection en Google Messagespowered by artificial intelligence, helps automatically protect Android users from fraudulent messages. Pixel and Samsung device users can also enable the feature Scam Detection dentro de Phone by Google to identify potentially fraudulent calls.
• Gmail adds support for Brand Indicators for Message Identification (BIMI)improving verification of legitimate senders.
• Through RCS for Businessbusinesses must verify their identity, allowing users to know exactly which organization is communicating with them.
• Google has promoted and integrated authentication mechanisms STIR/SHAKEN at the network level in multiple countries to reduce phone number spoofing.

According to the company, Fake Call Detection represents the next major advance in its protection strategy against fraud and scams. As cybercriminals develop increasingly sophisticated techniques, the company ensures that it will continue to expand and strengthen its defense mechanisms for users.
