[0002] With the increasing functions of mobile phones, the computer may no longer be a carry-on item. Sometimes it is necessary to lend the computer to other people, or the computer is placed in the office or at home, and the computer owner is out and needs some information in the computer urgently. Help open the computer to obtain the required information, or the computer is placed out of sight of the computer owner, and the computer owner cannot know whether someone has used his computer, thus bringing computer security risks

[0003] At present, most of the guarantee systems for computer security login log in to the computer through simple password login, fingerprint login, etc., but both password login and fingerprint identification login have their drawbacks. For password login, the password is easy to be stolen. Password leakage will directly lead to information leakage. For fingerprint identification login, on the one hand, fingerprints are easy to be destroyed unintentionally, resulting in insecure login. On the other hand, fingerprints are easy to be printed on the surface of glass, plasticine, etc. At present, when logging into the computer, the computer will send a verification code to the associated user's mobile phone, and the user needs to provide the verification code before logging in.
