Title: Wireless Biometrics-Based Locking System

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to a locking system. More specifically, the present invention relates to a locking system that enables a user to wirelessly unlock a locking device by scanning an appropriate biometric identifier with a biometric scanning device. 
     BACKGROUND OF THE INVENTION 
     Locking systems are invaluable pieces of equipment that enable a use to secure personal property. While useful, traditional locking systems have several drawbacks. Namely, they require the user to remember a code or to carry a key. Both these security measures have flaws. For a code-protected system, the user may forget the code. Similarly, for a keyed-entry system the user may lose the key. Additionally, both security measures are vulnerable to the key or code being stolen by nefarious individuals. 
     The present invention addresses these shortcomings, among others, of traditional locking systems. To accomplish this, the present invention is a locking system that employs biometric identifiers in lieu of keys and codes. This enables the present invention to function as a keyless entry system for which the user never has to remember a code or carry a key. In addition to keyless entry, the present invention employs a wireless locking mechanism that can be remotely controlled by a biometric identifier capturing device. This enables the user to wirelessly control multiple locking mechanisms from the biometric identifier capturing device.

     DETAIL DESCRIPTIONS OF THE INVENTION 
     All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention. 
     Referring to  FIG. 1  through  FIG. 8 , the present invention is a wireless biometrics-based locking system. This system is designed to enable the use a biometric identifier as a key for engaging or disengaging a remotely situated locking mechanism  11 . To achieve this functionality, the present invention comprises at least one locking device  1  and at least one biometric-scanning device. The wireless locking device  1  is a locking mechanism  11  that is capable of wirelessly sending and receiving data. Embodiments of the wireless locking device  1  are designed to function as locks for various systems including, but not limited to, doors, luggage, chests, and vehicles. The biometric-scanning device is an electronic system capable of acquiring the biometric identifier and determining the identity of the individual associated to the biometric identifier. Additionally, the biometric-scanning device is designed to be a computing device capable of wirelessly relaying commands and data between the user and the wireless locking device  1 . The biometric scanning device  2  can refer to a variety of devices including, but not limited to, smartphones, security panels, and keyless entry pads for doors. 
     Referring to  FIG. 8 , to employ the system of the present invention, the user first captures the biometric identifier on with the biometric scanning device  2 . Preferably, the biometric identifier is a fingerprint. However, the term biometric identifier can refer to a variety of markers including, but not limited to ocular, facial, and vocal. The biometric scanning device  2  then compares the biometric identifier to a set of stored biometric identifiers to determine the user&#39;s identity. If the biometric identifier matches a stored identifier, then the biometric scanning device  2  transmits a command that directs the wireless locking device  1  to become unlocked. Alternatively, the biometric scanning device  2  may give the user an option to unlock a plurality of the wireless locking devices  1 . The user is then free to choose the wireless locking devices  1  that should be unlocked while leaving others locked. 
     Referring to  FIG. 1 ,  FIG. 5 , and  FIG. 6 , to achieve the above-described functionalities, the wireless locking device  1  comprises a locking mechanism  11 , a lock control system  12 , and a secondary wireless communication system  13 . Additionally, the biometric scanning device  2  comprises a primary biometric sensor  21 , a primary wireless communication system  22 , and a scanner control system  23 . The locking mechanism  11  is a mechanically actuated device that can be locked and unlocked upon receipt of an appropriate command. The lock control system  12  is preferably a microcontroller capable of governing the operations of the locking mechanism  11  and the wireless communication system. To that end, the lock control system  12  is electronically connected to the locking device  1  and the secondary wireless communication system  13 . Accordingly, the lock control system  12  is used to send and receive data using the secondary wireless communication system  13 . Additionally, the lock control system  12  sends commands to the locking mechanism  11  that cause the locking mechanism  11  to transition between a locked configuration and an unlocked configuration. 
     Referring to  FIG. 5  and  FIG. 6 , the scanner control system  23  is a microcontroller that is integrated into the biometric scanning device  2 . The scanner control system  23  is electronically connected to the primary biometric sensor  21  and the primary wireless communication system  22 . Consequently, the scanner control system  23  functions similarly to the lock control system  12 , in that the scanner control system  23  governs the operations of the electrical components of the biometric scanning device  2 . The primary wireless communication system  22  is communicably coupled to the secondary wireless communication system  13 . As a result, the biometric scanning device  2  is able to wirelessly issue commands that cause the wireless locking device  1  to transition between the locked configuration and the unlocked configuration. The primary wireless communication system  22  and the secondary wireless communication system  13  are designed to transmit and receive data via wireless communication protocols that include, but are not limited to, Bluetooth, Wi-Fi, GPRS, IR, and ZigBee. 
     Referring to  FIG. 1  and  FIG. 6 , the wireless locking device  1  is designed to be a tamper-resistant device that remains operable even under extreme conditions. To facilitate this, the wireless locking device  1  further comprises a lock housing. The lock control system  12  and the secondary wireless communication system  13  are mounted within the lock housing. As a result, the lock control system  12  and the secondary wireless communication system  13  are isolated from hazards in the environment that include, but are not limited to, moisture damage, fire damage, and nefarious individuals. Additionally, the locking mechanism  11  is integrated into the lock housing. Accordingly, the locking mechanism  11  and the lock housing form a self-contained unit that is protected from the aforementioned hazards. 
     Referring to  FIG. 2  and  FIG. 6 , the present invention expands on the concept of the wireless locking device  1  being a self-contained device by employing components that increase the means by which the user is able to interact with the wireless locking device  1 . Specifically, the wireless locking device  1  further comprises a lock human interface device (HID)  15 , a secondary biometric sensor  16 , a position tracking system, and an emergency keyhole  18 . The lock HID  15  is preferably a keypad that enables the user to enter a passcode in lieu of providing a biometric identifier. The lock HID  15  and the secondary biometric sensor  16  are laterally mounted onto the lock housing. Accordingly, the placement of the lock HID  15  and the secondary biometric sensor  16  facilitates manipulation by the user. That is, the lock HID  15  and the secondary biometric sensor  16  are positioned such that the user may input commands or the biometric identifier whether the wireless locking device  1  is in the locked configuration or the unlocked configuration. The lock HID  15  and the secondary biometric sensor  16  are electronically connected to the lock control system  12 . As a result, the lock control system  12  is able to interpret the information gathered by the lock HID  15  and the secondary biometric sensor  16 . Further, the lock control system  12  governs the operations of the lock HID  15  and the secondary biometric sensor  16 . Some embodiments of the wireless locking device  1  are equipped with internal power supplies. These embodiments function as portable locks that can be used in locations where electrical power is not readily available. The position-tracking system  17  is mounted within the lock housing and is electronically connected to the lock control system  12 . Consequently, the position-tracking system  17  is able to actively monitor and report the physical location of the wireless locking device  1 . The emergency keyhole  18  is integrated the lock housing. Additionally, the emergency keyhole  18  is operatively coupled to the locking mechanism  11 , wherein actuating the keyhole causes the locking mechanism  11  to become locked or unlocked. As a result, the user is able to manually transition the locking mechanism  11  between the locked configuration and the unlocked configuration with the use of an appropriate key. 
     Referring to  FIG. 5 ,  FIG. 7 , and  FIG. 8 , the biometric scanning device  2  is preferably a portable handheld device. As such, the biometric scanning device  2  further comprises a scanner housing  24  and a scanner HID  25 . The scanner housing  24  is an ergonomic enclosure within which the scanner control system  23  and the primary wireless communication system  22  are mounted. The scanner HID  25  is laterally mounted onto the scanner housing  24  and electronically connected to the scanner control system  23 . Consequently, the scanner HID  25  relays information between the user and the scanner control system  23 . Preferably, the biometrics scanning device is able to connect to and communicate with the wireless locking device  1  directly. However, some embodiments of the present invention comprise at least one remote server  3 . The remote server  3  is used to facilitate transferring data between the wireless locking device  1 , the biometric scanning device  2 , and any number of external users. Moreover, the remote server  3  is used to execute a number of internal processes for the present invention and is used to store user information, as well as, security protocols, and biometric identifiers. In these embodiments, the remote server  3  mediates the connection between the biometric scanning device  2  and the wireless locking device  1 . This connection scheme enables the biometric scanning device  2  to control the wireless locking device  1  even when the wireless locking device  1  is outside the communication range of the primary wireless communication system  22 . 
     Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
