Google has announced a new security feature called Fake Call Detection for its Phone by Google app, designed to protect users from increasingly advanced impersonation scams powered by AI.
The feature targets a rising threat where scammers use spoofed numbers and AI-generated voices to trick people into believing they are speaking with trusted contacts.
How Modern Call Scams Work
Google explains that these scams usually happen in two stages:
First, attackers spoof a familiar phone number, such as a family member or close friend. They route calls through internet-based tools so the incoming call appears legitimate on the user’s screen.
Next, scammers use widely available AI deepfake voice tools to imitate real voices. These systems can replicate the tone of a relative, employer, or authority figure, making the call sound extremely convincing.
According to security experts referenced by Google, modern deepfake voices have become so realistic that most people can no longer reliably detect them during live calls.
How Fake Call Detection Works
The new protection system works only when both users are using the Phone by Google app.
When a real call takes place, both devices silently exchange a verification signal using end-to-end encrypted RCS communication. This process confirms that both sides are genuinely connected.
If a scammer tries to impersonate a contact, this verification signal will not exist. In that case, the app will immediately show a warning alert, helping users identify suspicious calls in real time.
Google emphasizes that this verification is fully private and encrypted, meaning no call content is exposed.
Availability and Rollout
The feature will be enabled by default, but users can disable it in the app settings if they choose.
Fake Call Detection is rolling out globally this month on devices running Android 12 and newer. The first devices to receive it will be Google’s own Pixel smartphones.
Users with other Android devices can install the Phone by Google app from the Play Store and set it as their default dialer to access the protection.
Why This Matters
With AI-driven scams becoming more common, Google’s new system aims to add an extra layer of trust during live phone calls. By verifying both ends of a conversation in real time, the company hopes to reduce successful impersonation attempts and protect users from fraud.
