What is the technology of "verification code security protection" for teddy bear mobile phones?

The function of "verification code security protection" is exclusively developed by Teddy Bear Mobile, and the technology is mainly shielded from two aspects. On the one hand, dynamic password encryption makes it impossible for malicious applications to identify the real verification code, thus protecting users' personal information; On the other hand, for the short message content displayed after the screen is locked, the verification code will not be displayed directly when the protection is started, so as to prevent the user from inadvertently revealing personal information.
