AI fraud using face-changing and onomatopoeia technology is indeed a modern fraud method. While this threat cannot be completely eliminated, here are some suggestions for protecting against these types of scams:

1. Stay vigilant: Remain skeptical of any unverified information. Don’t trust information from strangers via social media, email, or phone calls.

2. Confirm identity: Ensure the identity of the other party before involving financial transactions, sensitive information or important decisions. Verify the authenticity of the other party through other channels (such as official website, official phone number, etc.).

3. Be wary of emergencies: Scammers often create emergencies to speed up the decision-making process. When faced with a situation that requires immediate action or sensitive information, remain calm and prioritize verification.

4. Don’t share personal information: Avoid sharing personal information on untrusted platforms or with unreliable individuals. This includes bank account information, ID numbers, social security numbers, etc.

5. Strengthen password and account security: Use strong passwords and change them regularly. Enable multi-factor authentication for added account security. Choose a trustworthy online trading platform carefully.

6. Keep your software updated: Keep your operating system, applications, and security software updated. This helps fix known vulnerabilities and security issues.

7. Educate yourself: Understand the different types of online scams and scams, and learn how to identify and avoid them. Many agencies and organizations offer educational resources on cybersecurity and fraud prevention.

8. Report suspicious activity: If you notice suspicious activity or suspect you have been a victim, please immediately report the incident to your local law enforcement agency and contact your bank or financial institution.

In short, staying vigilant, properly protecting personal information and not trusting strangers are important steps to prevent AI fraud. In addition, it is crucial to stay informed and take precautions against new fraud methods.
