Google announced a new security feature that aims to protect Android users against artificial intelligence-supported phone scams. The system, called “Fake Call Detection”, verifies whether the caller is really who he claims to be and warns users against possible fraud attempts. Artificial intelligence-based voice cloning technologies, which have developed rapidly in recent years, have made it easier for fraudsters to gain trust by imitating the voices of familiar people. Google’s new solution aims to detect such attempts at the search stage.
While advances in artificial intelligence technologies provide benefits in many areas, malicious uses are also increasing at the same rate. The most important of these is voice cloning. Today, thanks to advanced productive artificial intelligence tools, voices that are very similar to real people can be created even from short voice recordings. This situation paves the way for imitation of the identities of trusted people, especially family members or close friends. During spoofed calls, scammers can try to persuade users to send money or share sensitive information by imitating both the caller ID and voice.
How does Android fake call detection system work?
The new system developed by Google works in the background without requiring any action from the user. When a person calls you from a number saved in your contacts and both parties are using Google’s Phone app, the calling device sends an encrypted verification signal to the receiving party. This process, which resembles a digital handshake mechanism, verifies that the call was indeed made from the relevant person’s device.
This authentication mechanism is built on end-to-end encrypted RCS technology. Google states that the verification process is completely confidential and user data is not shared. Thus, the system aims to ensure security while not compromising privacy.
However, when fraudsters make a call by impersonating a person’s phone number, the verification signal cannot be received. In such a case, the Android device contacts that person’s real phone to check whether the call actually came from that person. If the device on the other end verifies that it is not making an active call, a possible fake call warning appears on the user screen. The warning warns that the call may not be reliable and recommends ending the call. Since all these processes occur within seconds, the fraudster’s opportunity to exert psychological pressure or manipulate the user is significantly reduced.
According to the information provided by Google, the fake call detection feature will be turned on by default. The distribution process will begin later this month and will first reach Pixel devices running Android 12 or newer. The scope of support is expected to be expanded later.
However, there are some conditions for the system to work. Both the caller and the called person must use the Google Phone application. In addition, the user receiving the call must have RCS support enabled on their device via the Google Messages application. These requirements may limit the scope of use in the first stage. Even so, Google’s approach brings an additional layer of trust to phone calls at a time when AI-powered scams are on the rise.
As voice cloning technologies become more accessible, phone scams are also becoming more complex. This new verification system offered by Google offers a technical solution against fake voice and number impersonation methods. Although all users will need to use the necessary applications and services, it seems possible that if the system becomes widespread, it can become one of the tools that can reduce the impact of phone-based fraud attempts.
