Shopping, socializing, ticket purchasing, social security, stocks ... Now everyone's mobile phones are bound to accounts of various platforms, which are not only related to money, but also linked to work and privacy. Moreover, these websites also attach security verification to the mechanism of mobile phone verification code.

The verification of SMS has the advantages of low cost, simple operation and high relative safety factor. It has been widely used in recent years, but it also has a natural defect, that is, it will be intercepted during transmission.
