On the news of June 3rd, Google announced today that Android A new feature called Fake Call Detection was introduced to counter the growing threat of electric fraud.

This feature is called the industry's first initiative by Google, when both users and address persons use Phone by Google This is when the system is able to detect and mark the call of a suspected counterfeit contact. Earlier, Google had introduced a certified caller function for financial institutions to alert users against fraudulent calls from financial institutions such as counterfeit banks.

Google stated that, with the development of artificial smart voice cloning, fraudsters are now able not only to forge telephone numbers, but also to use Deepfake techniques to mimic the voices of relatives, bosses or other authorities. For example, telephone calls may be shown as “mothers”, and the sound of the other side of the telephone is very similar to that of the real contact, but in practice they are used by AI to use false voice to attempt fraud on grounds of urgency.

According to the latest Global Financial Fraud Threat Assessment published by Interpol in March this year, frauds of the type of identity fraud have become one of the major causes of losses of more than $40 billion worldwide (IT House Note: the current exchange rate is approximately RMB 2.71 trillion). At the same time, this type of fraud is one of the most reported types of fraud in the United States FTC, with related losses amounting to $2.95 billion in 2024 alone (the current exchange rate is approximately RMB 2004 million).

Google noted that as more and more users refused to pick up calls from strangers, fraudsters were turning their tactics towards impersonating familiar numbers. Experts noted that the current AI deep audio-forgery technology had made it difficult for most people to discern the extent of authenticity by hearing alone.

To address this problem, Google introduced a new certification mechanism in Android. This function is by default activated and automatically run in the back. When the contact in the address book calls and both users Go.At ogle Phone, the other party's equipment sends a silent confirmation signal to the user's device in real time to prove that the call actually originated from the real device of the contact. This number shakes hands based on end-to-end encrypted RCS technology and ensures privacy.

If the fraudster falsifies the contact number and is unable to send this authentication signal, the receiving party ' s equipment immediately discovers the anomaly and initiates a second confirmation of the real equipment of the contact.

If the other party's device provides feedback that “no call is currently being made”, there will be a bullet window warning on the user's side of the screen, which is recommended for immediate suspension. Google indicated that such a proactive warning mechanism could help users identify, in real time, deep-false voice and number disguise attacks during fraud. The user can also turn off this feature at any time in the Phone by Google settings.

Google stated that the false call detection function would begin this month to be delivered to the global market, with the first equipment to support the loading of Android 12 and above and the first landing of the Google Pixel series. As Phone by Google is already the default telephone application for most Android devices, most users are directly supported.

Google stated that the function was based on open standard RCS construction and was not limited to single equipment or application ecology, and that other application developers and equipment manufacturers would be able to use the technology in the future to enhance the industry ' s protection against telephone fraud.
