In recent days, the topic of AI face changing scams has attracted social attention.

The Baotou police recently released a typical case of using AI to commit telecommunications fraud. A fraudster used AI face changing and onomatopoeia technology to pretend to be friends and defrauded Mr. Guo, the legal representative of a technology company in Fuzhou. After verifying the other person's identity through video chat, Mr. Guo was scammed out of 4.3 million yuan by the fraudster within 10 minutes.

So, how to determine AI fraud, and what methods and means can prevent AI fraud? At the end of May, a reporter from Science and Technology Daily interviewed relevant experts.

AI face changing scams are difficult to distinguish

AI fraud refers to the criminal activity of using AI technology to imitate and fabricate the voice, face, video and other information of others, and engaging in deception, extortion, extortion, and other activities. Lu Zhaoming, an associate professor at the School of Information and Communication Engineering at Beijing University of Posts and Telecommunications, told Science and Technology Daily that scammers will use methods such as making harassing phone calls, recording and extracting the voice features of the scammers and their important contacts, and then using AI technology for voice synthesis to relax the vigilance of the scammers, and then using forged voices to commit fraud.

Facial effects are more likely to gain the trust of the other party, and scammers can use AI technology to change their faces and disguise themselves as anyone. "Lu Zhaoming said that scammers will use AI technology to replace the faces of others with the faces of designated individuals, impersonating the relatives and friends of the scam victims, and using synthetic videos or photos to" confuse the fake with the real ", disrupting the scam victims' vision, and then carrying out the scam.

Peng Zhijun, Deputy General Manager of Security at An Tian Mobile, stated in an interview with a reporter from Science and Technology Daily that due to the highly realistic, difficult to track, targeted, and diverse methods of AI fraud, victims often find it difficult to distinguish between true and false, thereby reducing their vigilance. At the same time, criminals are hiding in the dark corners of the internet, which also brings difficulties for the police to investigate.

The key to problem governance lies in "law"

How to address the risk of AI technology abuse and prevent AI fraud?

The key lies in the word 'fa'. This' law 'includes both the application of scientific and technological methods and the laws and regulations of rigid governance.

In terms of science and technology, the technological equipment for combating telecommunications network fraud has developed rapidly. For example, the "AI-3300 Smart Eye Video Image Authentication Workstation" developed by Xiamen Meiya Baike Information Co., Ltd. can not only identify images that have been tampered with using traditional forgery methods, but also identify images that have been altered, beautified, generated, or replicated using deep forgery technology, providing technical support for the public security and judicial industries.

In terms of laws and regulations, in December 2022, the Administrative Provisions on the Deep Synthesis of Internet Information Services was released, which clearly restricts the generation, replacement, manipulation of faces, synthesis of voices, and imitation of voices. After the release and implementation of this regulation, a previous app that focused on AI face changing was removed from the shelves after being interviewed by regulatory authorities. The reason for the removal was that "such face changing infringed on citizens' portrait rights".

Attention to unnatural details

For ordinary people, AI fraud is not completely 'impossible to prevent', which requires everyone to have a discerning 'eye'. Peng Zhijun told Science and Technology Daily that although the voice and facial expressions generated by AI are already quite realistic, there may still be some unnatural details. The specific details include the rhythm and pitch changes of AI generated speech, as well as the facial expression transitions of AI generated images, all of which are significantly different from the original video.

There are many techniques for judgment and discrimination. Peng Zhijun stated that during a video call, users can have the other person display full body features and then observe whether the face has disappeared or undergone special changes to detect the possibility of facial replacement. Users can also have the other party slowly shake a piece of white paper in front of their face to observe if flickering occurs, in order to determine if there may be a face change phenomenon.

No matter how powerful a scam is, in the final analysis, it is all about using fraudulent means to gain the trust of the other party and obtain public or private property. For individuals, multiple verifications and confirmations of identity are necessary to avoid and prevent the occurrence of scams. "Lu Zhaoming said, especially when it comes to important matters such as money, property, and privacy, it is even more important to be cautious and ask the other party to provide more evidence and engage in more communication, And verify the accuracy of their identity and answers to rule out the possibility of AI technology deception.

The public should have a sense of vigilance against high-risk behaviors in their daily lives. Be vigilant and carefully verify the authenticity of urgent transfers, large deposits, or other unusual requirements. Lu Zhaoming reminds not to be confused by high returns or urgent situations. When the true identity cannot be determined, special attention should be paid and remittances should not be rushed to avoid being deceived. At the same time, it is recommended to set the arrival time to "2-hour arrival" or "24-hour arrival" to reserve processing time.
