As shown in fig. 4, in the case that the computer system is connected with a fingerprint device and the central management unit stores both the fingerprint information and the password information of the user, the system is shown in fig. 1 and 4 in combination with the workflow chart of the system: the user selects the user name first, the computer detects whether the fingerprint device is connected, the detection result is that the fingerprint device exists, at this time, an input selection interface is displayed for the user to select, if the user selects the password authentication mode to log in, the password extraction module 30 extracts the password information input by the user, and the password information is authenticated by the authentication module 40: by directly entering the operation system after authentication failure reaches a preset number of times, displaying an input fingerprint interface, inputting a fingerprint by a user, and authenticating by an authentication module 40: the operating system may also be entered directly after passing (in which case the password may be modified prior to entering the operating system), and the interface may be locked after the authentication fails a predetermined number of times.
The user selects to input the fingerprint mode to log in the process similar to the process of selecting the password mode to log in, and the user can log in by inputting the password after the fingerprint is failed to input the preset times.
The invention breaks through the defect that the fingerprint can be authenticated only by the password in the prior art by selecting the autonomous login mode of the user, and the user can freely select the login verification mode according to the use of the user when using the computer, so that the autonomy is stronger.
Although the present invention has been described with reference to the above preferred embodiments, it should be understood that the present invention is not limited to the above embodiments, and that various changes and modifications can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
