Why did you suddenly receive the verification code of Fuhui Travel?

The mobile phone number that receives short messages is usually the one that is bound to the identity when registering. Under normal circumstances, personal information should be protected and not leaked at will to prevent property losses.

CAPTCHA, abbreviated as CAPTCHA, is a public automatic program used to distinguish whether users are computers or people. The application of verification code is a common way adopted by many websites, which can not only prevent malicious password acquisition, ticket brushing and forum flooding, but also effectively prevent a hacker from constantly trying to use a specific program to log in to a specific registered user to make a breakthrough. Captcha questions are generated and judged by computers, but only humans can answer them. The computer can't answer the Captcha question, so the user who answers the question can be considered as human.
