Recently, a female Internet celebrity with millions of fans broke out an "AI face change" incident. The female Internet celebrity said that her video comment area suddenly flooded with many people saying that they had seen her "videos", but she had never posted such a video.
She opened the video suspiciously, and found that the girl in it looked exactly like her, but did some indescribable movements, which made her feel very angry and helpless. She immediately realized that her face might have been stolen by artificial intelligence (AI).
AI technology is developing rapidly, and the recent explosion of AI face change, everyone does not know whether it has been played.
You only need to provide a photo with a face, you can replace yourself with the male (female) protagonist in the video and TV series, and the degree of fidelity is very high, without a sense of violation.
Someone replaced Lu Han's face with the role of "Little Dragon Girl" played by Liu Yifei, which is the following effect. If I hadn't seen "The Condor Heroes" beforehand, I thought it was me.
Common methods of AI fraud
The first: sound synthesis
Scammers extract someone's voice by recording harassing phone calls, etc., and synthesize the voice after obtaining the material, so that they can deceive the other party with fake voices.
Case
A company's financial Xiaowang received a call from a leader, asking to immediately transfer 20,000 yuan to the supplier, and sent the transfer information by email, the reason for the transfer was to avoid paying late fees. Because the boss's accent is very realistic, Xiao Wang believed it to be true, completed the transfer within 1 hour, and found that he was deceived.
The second type: AI face change
The face effect is easier to gain the trust of the other party, and the scammer uses AI technology to change the face, you can disguise yourself as anyone, and then confirm the information through video, which is really unpreventable!
The scammers first analyze all kinds of information posted by the public online, and according to the scams to be carried out, they use AI technology to screen the target group. Use AI to change faces in video calls to deceive trust.
Case
Recently, Xiao Li's college classmates borrowed money from her through QQ. The other party called a four- or five-second video call, and Xiao Li saw that it was indeed him, so he transferred 3,000 yuan with confidence. However, she felt abnormal during the second transfer, so she called the other party again, only to learn that her classmate's account had been stolen and report the crime. The police judged that the video was most likely a face-changer.
The third type: forwarding WeChat voice
WeChat voice can actually be forwarded, this operation is simple! After stealing the WeChat ID, the scammers "borrowed money" from their friends, and in order to gain the trust of the other party, they would forward the previous voice and then defraud the money.
Although WeChat does not have a voice forwarding function, they achieve voice forwarding by extracting voice files or installing unofficial versions (plugins).
The fourth type: screening deceived people through AI technology
Instead of aimlessly casting a comprehensive net, the crooks target specific objects with ulterior motives. They will screen the crowd according to the tricks they want to carry out to select the target audience.
For example, when committing financial fraud, small partners who often collect investment information will become potential targets.
The use of AI technology, coupled with the interpretation of routines and scripts, such a fraud method, can the friends hold it?
How to prevent it?
HOME
In the face of fraud using new means such as AI artificial intelligence, we must keep the following points in mind:
Multi-factor authentication to confirm identity
01
When it comes to transfer transactions and other behaviors, partners should pay special attention to whether the other party is themselves through telephone, video, etc.
If the identity of the other party cannot be confirmed, you can set the arrival time to "2 hours to arrive" or "24 hours to arrive" to reserve the processing time. Try to ask for specific information by phone to confirm that the other person is the person.
Even if the other party uses AI technology to deceive, they can further confirm their identity by asking questions. It is recommended that everyone better transfer money to each other's bank account and avoid transferring money through social software such as WeChat. On the one hand, it is conducive to verifying the identity of the other party, and on the other hand, it is also helpful to follow up the transfer information.
Protect information and avoid temptation
02
To strengthen the awareness of personal information protection, partners should beware of all kinds of information leakage, whether on the Internet or social software, try to avoid exposing their information too much.
Be vigilant against links such as advertisements, lotteries, and dating sent by unknown platforms, and do not fill in personal information at will, so as not to be "accurately hunted" by scammers.
Remind each other and prevent together
03
These high-tech fraud methods have confused many small partners. Police officer Shu Li also reminded you to remind and warn your relatives and friends to improve their security awareness and ability to deal with high-tech fraud, and jointly prevent being deceived.
Do a good job in publicity and prevention for the elderly at home. Remind the elderly to put down the phone when receiving a phone call or text message, call the family again to confirm, and do not transfer money rashly.
Resist temptation and be vigilant
04
Friends should learn to refuse temptation and be vigilant. Avoid taking advantage of the mentality and be wary of strangers "giving courtesy" for no reason.
If you don't know these tricks of the scammers in advance, the possibility of being scammed is very high. Or that sentence:
You are not currently deceived, not because you are smart or because you have no money, but the "script" that suits you is still on the way.
