Verification method, device, equipment and system based on password and private data

The embodiment of the invention discloses a password-based verification method, device, equipment and system and a private data-based verification method, device, equipment and system. The password-based verification system comprises an application layer subsystem and a password adaptation layer subsystem, wherein the application layer subsystem is used for acquiring a verification request for authenticating or authenticating a target user and sending the verification request to the password adaptation layer subsystem, and the verification request comprises verification data required for authenticating or authenticating the target user; the password adaptation layer subsystem acquires reference password data for authenticating or authenticating the target user from a password database, verifies the verification data based on the reference password data to obtain a verification result, and sends the verification result to the application layer subsystem; and the application layer subsystem determines whether t
