Background
With the continuous development of computer technology, information security has become the focus of general attention of computer users. Particularly, in special industries such as business and military, the protection of computer information is particularly important, and the situation that the computer information is destroyed will not be left to the enemy.
The prior art provides a method for identifying the identity of a computer user by a password identity identification method, which is briefly described as follows: after the computer is started and BIOS self-checking is completed, and after the operating system starting file is read, the password input interface is output, so that the user can input the starting password, the starting password input by the user can be verified, the operating system is started after the verification is successful, and the computer starting process is stopped when the verification is unsuccessful, thereby ensuring the safety of the computer system. However, the password identification method requires the user to remember a preset boot password, an excessively long boot password is inconvenient for the user to remember, and an excessively short boot password is easy to crack, and generally, the password identification method stores the preset boot password in a hard disk, so that the user identity can be identified only after the computer hard disk is accessed after an operating system boot file is read, and therefore, the simple password identification method cannot meet the security requirement of a computer system easily, and computer information is easy to be stolen by lawless persons.
On the other hand, however, when the computer is locked incorrectly and information is destroyed when a wrong operation occurs or the password fingerprint input device is verified incorrectly, the information of the user is lost, and the user is lost. Furthermore, if the computer is unable to perform wireless communication, the computer cannot be controlled to automatically destroy useful information, which also fails to effectively protect information.
