Google and Android: Advanced Detection of Deepfake Calls

Google and Android Roll Out Fraudulent Call Detection

Google has announced the rollout of a new feature on Android aimed at detecting fraudulent calls, a direct response to the rise of scams using deepfake AI technology. This feature will be integrated into the Phone by Google app, available for devices running Android 12 and later. The rollout will begin this month, initially on Pixel devices.

In light of users' growing reluctance to answer unknown numbers, scammers have changed their tactics. They are now spoofing trusted phone numbers and using deepfakes to mimic familiar voices, such as those of family members or authority figures, in order to deceive victims. For example, a user might receive a call appearing to come from "Mom," with a voice identical to hers, but in reality, it is a scammer using AI to request money under the pretense of a fictitious emergency.

How Fraudulent Call Detection Works

This new feature is enabled by default and operates automatically in the background. It relies on a sort of "digital handshake" between devices. When a contact calls and both parties are using Phone by Google, a silent confirmation signal is sent to authenticate the call. If a scammer attempts to impersonate a trusted contact, this signal will be absent, and the user's device will be immediately alerted. A message will be sent to the real contact's device for verification. If they confirm they are not making the call, a warning will appear, advising to hang up immediately.

Google explained in a blog post that if a scammer tries to impersonate your trusted contact, the initial confirmation signal will be missing. Your device will notice this instantly and send a message to your contact's real device for verification. If their actual device responds, "I'm not making any calls right now," you will receive a warning on your screen advising you to hang up immediately.

This technology relies on Rich Communication Services (RCS), allowing other applications and businesses to adopt this security system.

Other Android Updates

In parallel, Google announced additional updates for Android. A new feature in Google Photos will allow users to mix and match outfits virtually. This "wardrobe" feature will be available next week for users in the United States, India, and Brazil with Android 10 and above.

Additionally, Google Play Books is introducing "Catch me up," a feature that provides summaries to help users pick up a story. Users will also be able to highlight passages to ask questions. These features are available starting today for certain titles in English.

Finally, Google’s "Circle to Search" feature now allows users to search for complete outfits all at once, simplifying the process of finding clothing items. This update is accessible on all devices running Android 14 and above, equipped with Circle to Search.
