Description

MODULAR SMART PADLOCK SYSTEM FOR PROTECTION OF

DISTRIBUTED ASSETS

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to, the benefit under 35 U.S.C. § 119 of, and incorporates by reference herein in its entirety U.S. Provisional Patent Application No. 62/634,283, filed February 23, 2018, and entitled“Modular Smart Padlock System for Protection of Distributed Assets.”

TECHNICAL FIELD

The present systems, apparatuses, and methods relate generally to padlocks and, more specifically, to a modular padlock system.

BACKGROUND

Traditional padlocks require a key or combination for access. Key management of traditional padlocks is insecure, costly, and antiquated. For example, the city of Austin, TX, has over 20,000 fire utility boxes with one master key. A recent breach has caused the city to have to rekey these boxes at a cost of over $2,000,000. Key management and retrieval is a laborious and timely process.

In contrast, smart padlocks provide digital alternatives to keys but require batteries and generally lack connectivity. Thus, smart padlocks store their access information locally, which makes them only as secure as the update to the lock.

Similarly, connected padlocks require power and connectivity to provide added flexibility through real-time authentication. Therefore, there is a long-felt but unresolved need for a keyless/combination-less lock that is removably powered and connected to ensure security and ease of use.

Overview Briefly described and according to one embodiment, aspects of the present disclosure generally relate to systems and methods for a modular padlock system. A need arises where an organization or an individual may have a significant number of locations that should to be secured and, in the case of the organization, a smaller distributed workforce that needs to access those secured locations. Rather than incur the risk, time, and expense of physical key management, the organization/individual seeks to digitalize its lock management system such that access to each of its secured locations may be controlled from a single central location via a network (e.g., a secure or unsecured connection, Bluetooth, wireless or wired local-area networks (LANs), cell network, the Internet, etc.). Accordingly, the organization/individual may increase the security at each of its secured locations, while it decreases its potential financial exposure in the event of a lost key, by implementation of a modular padlock system as described in the current disclosure.

The above and further features of the disclosed exemplary modular padlock system will be recognized from the following detailed descriptions and drawings of particular embodiments. In various embodiments, the modular padlock system includes a lock housing unit and a control unit. In some embodiments, the lock housing unit includes a shackle, a motor, a shackle sensor, a blocker, a connector, and an encryption chip. Generally, the shackle secures the lock housing unit to a desired item or location. According to at least one embodiment, the shackle is shaped like an upside down letter “u”. In at least one embodiment, the shackle is rectangular in shape. Additionally, in particular embodiments, the motor locks and unlocks the shackle by rotating a blocker (e.g., a physical piece that prevents the shackle from moving or being removed from the lock housing unit). In at least one embodiment, the shackle sensor detects whether the shackle is in a locked or unlocked position. In particular embodiments, the connector provides a mechanism for transferring power and data between the lock housing unit and the control unit. Additionally, in various embodiments, the encryption chip enables secure transfer of data between the lock housing unit and the control unit (in one embodiment, via the connector).

embodiment, the circuit board 616 also contains a speaker 614 to provide audible user feedback (e.g., instructions, indications of approval or denial of an access key, etc.), a light 620 (e.g., LED, etc.) to provide visual feedback, a USB port 612 for charging and updating the control unit 114, and an input method actuator 618 for toggling the input method 608 between on and off states. Generally, the present disclosure places no limitations on the size or shape of the control unit 114.

In various embodiments, the central management system permits the management of lock housing units (e.g., lock housing unit 112) and control units 114. In some embodiments, the central management system, i.e., lock system, provides a mechanism for maintaining an inventory of lock housing units and control units. In at least one embodiment, the lock system provides a mechanism for managing users and access permissions to lock housing units.

In various embodiments, to lock a lock housing unit 112, the control unit 114 is attached and paired to the lock housing unit via the connectors 508 and 600. Generally, the control unit 114 is powered and connected to a network via Bluetooth 606 or other wireless network 610. In one embodiment, a motor (e.g., motor 506) moves and locks a shackle (e.g., shackle 104) into place. In another embodiment, the shackle is manually manipulated and then locked into place by a motor. In some embodiments, upon locking the shackle, the lock housing unit records the time and location from the GPS 602 as well as the status of the shackle from the shackle sensor 504, and shares this information with the control unit 114 for management of the lock housing unit, auditing purposes, etc.

Continuing with this embodiment, to unlock a lock housing unit (e.g., lock housing unit 112), the control unit 114 is attached and paired to the lock housing unit via the connectors 508 and 600. Generally, the control unit 114 is powered and connected to a network via Bluetooth 606 or other wireless networking 610. In particular embodiments, the user may press the input method actuator 618 on the control unit 114 to turn on the input method 608. In various embodiments, upon a user’s attempt to authenticate via the input method 608, the control unit 114 securely transmits an access key generated from the input method 608 and the unique identifier of the lock housing unit to the lock system (e.g., central management system) via wireless communication for verification. Continuing with this embodiment, the lock system checks its access list to confirm that the access key is valid for that particular lock housing unit. In one embodiment, the lock system also receives and confirms that the location data corresponding to the lock housing unit is correct. In the event of a valid access key for the particular lock housing unit, the lock system (e.g., central management system) sends the control unit 114 an encrypted command to open the shackle (e.g., shackle 104). In the event of a failed access key for the particular lock housing unit, the lock system commands the control unit 114 to not open the shackle or does not send an encrypted command to open the shackle.

From the foregoing, it will be understood that various aspects of the processes described herein are software processes that execute on computer systems that form parts of the system. Accordingly, it will be understood that various embodiments of the system described herein are generally implemented as specially-configured computers including various computer hardware components and, in many cases, significant additional features as compared to conventional or known computers, processes, or the like, as discussed in greater detail herein.
