Embodiment Construction

[0021] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Reference is now made to the drawings, wherein like reference numerals are used throughout the different drawings to designate like or like parts.

[0023] Such as Figure 1-Figure 3 As shown, the fingerprint door lock 100 according to the present invention includes a door lock casing 1, a microprocessor unit (MPU: 2) arranged in the door lock casing 1, a fingerprint scanning module 3 for scanning user fingerprints, and a fingerprint scanning module 3 for password input. Password input unit 4.

[0024] The fingerprint door lock 100 also includes a storage unit 5 storing information about the fingerprint scanning module 3 and the password input unit 4, so that when the input information matches the information stored in the storage unit 5, the door lock 100 is locked or unlocked.

[0025] In addition, the fingerprint door lock 100 also ...

Abstract

The present invention discloses a fingerprint door lock. The fingerprint door lock comprises the following components: a microprocessor unit which is equipped in a door lock housing, a fingerprint scanning module which scans the user fingerprint, a cipher input unit which is equipped for inputting the cipher, and a storage unit for storing the information which is related with the fingerprint scanning module and the cipher input unit. The fingerprint door lock further comprises a module-driving-motor controller which receives a driving signal from the microprocessor unit. When the cipher input unit is used for inputting cipher or a specific key is pressed, the fingerprint scanning module is exposed from the door lock through the driving force of a driving motor which is operated by a starting control signal of the module-driving-motor controller. Therefore, the door can be successively opened through a double-process authentication procedure. Therefore, the safety of the door lock can be improved.

Description

technical field [0001] The present invention relates generally to a fingerprint door lock, and more particularly to a fingerprint door lock configured such that the fingerprint scanning module is exposed outside the door lock housing only when a separate authentication is successful, thereby preventing fingerprint The scanning module is damaged, and wherein since a separate authentication is required for the fingerprint recognition process, in other words, since a two-step authentication process is required to open a single door lock, the security of the door lock can be significantly improved. Background technique [0002] Recently in an information society, security against information leakage or security against entry of outsiders into company buildings and houses has been considered to be very important. [0003] Therefore, door locking methods for controllable or managed areas have been developed. [0004] Not only a locking method using a single key but also a locking...
