DETAILED DESCRIPTION
It will be readily understood that the instant components, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of at least one of a method, apparatus, and system, as represented in the attached figures, is not intended to limit the scope of the application as claimed, but is merely representative of selected embodiments.
The instant features, structures, or characteristics as described throughout this specification may be combined in any suitable manner in one or more embodiments. For example, the usage of the phrases “example embodiments”, “some embodiments”, or other similar language, throughout this specification refers to the fact that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment. Thus, appearances of the phrases “example embodiments”, “in some embodiments”, “in other embodiments”, or other similar language, throughout this specification do not necessarily all refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In addition, while the term “message” may have been used in the description of embodiments, the application may be applied to many types of network data, such as, packet, frame, datagram, etc. The term “message” also includes packet, frame, datagram, and any equivalents thereof. Furthermore, while certain types of messages and signaling may be depicted in exemplary embodiments they are not limited to a certain type of message, and the application is not limited to a certain type of signaling.
FIG. 1 illustrates an example communication network and an access assignment according to an example embodiment. Referring to FIG. 1, the network 100 includes an owner device 110 which manages the access settings for the lock, a server 120 which hosts the security application and provides a log of registered users, command encryption and other features, and a guest device 150 which may receive access to the security premises based on the access permitted by the owner device 110. A network 130 provides a communication medium for the devices to communicate and may be part of the Internet, cloud or other known network comprising one or more computers, servers, etc. In another embodiment, at least one of managing the access settings for the lock, hosting the security application, and providing a log of registered users, command encryption and other features, can be performed by one or more of the owner device 110, the server 120, the network 130, the guest device 150, and the wireless lock 160.
In operation, in one embodiment, the owner device 110 may offer a temporary access schedule to one more guest devices 150. A time window for permitting access may be designated along with one or more of a security question and answer, a specific encryption key, a location tracking procedure, etc. The owner device 110 may set up such criteria and transmit a temporary access instance to the server 120. The entire set of data, or a portion of that data, may be deemed an access package 142 which is further processed by the application server 120 prior to offering access to the guest device 150. Credentials 144 may be offered to the guest device 150. Once the guest device 150 accesses the credentials and provides any needed information (e.g., answers to security questions, passwords, a SMS message confirmation, etc.), the guest device may be used to wirelessly access 146 the wireless lock 160 and thereby unlock an object such as a door. In one embodiment, the secure environment may be a space that is locked by a door or by some other locking mechanism that secures a space, device, appliance, equipment, or item of property. For example, various items may be secured by a lock and may need to be unlocked to provide temporary access such as bicycles, vehicles or other transports, luggage carriers (for example in airports or train stations), as well as appliances or equipment.
The access signal 146 may be sent to the door wirelessly in any manner such as a near field communication message, a BLUETOOTH message, a WiFi message, a cellular message, etc. In another embodiment, the access signal 146 may be sent to the server 120 which communicates with the wireless lock 160 over a device at a residence, office, or other building, such as a WiFi/Internet router. Ultimately, the access information necessary to open the door may be sent and processed into a command that enables the wireless lock to unlock and permit access to a structure. This access information and/or command may expire after a certain amount of time or after a certain action is taken (for example, after the lock is unlocked one or more times).
One example method of operation may include providing a near field access control interface to prevent opening of a lock controlling access to a property until conditions determined by the access control interface, or other communicably coupled device and/or software program, are satisfied. The interface may include a time/date for the access, a challenge response question, and an identification (which may include a serial number, international mobile equipment identity (IMEI) of a mobile device, a pre-shared key, and/or an encryption algorithm). Responsive to detecting the mobile device with the identification at the time/date in the vicinity of the lock, the challenge response may also be requested by the mobile device, and responsive to receiving a correct answer to the challenge response, the lock may be opened. The access control interface may require the authorized mobile device in the vicinity of the lock as monitored by GPS or other location determination procedures.
The security functions may include a time of day based access, denoted as ‘T’, a challenge response denoted as ‘R’, a serial number of the guest device denoted as SN′, and a pre-shared key, denoted as ‘K’. The key encryption method used to encrypt one or more of the security functions may be any standard encryption method. In operation, the property owner or occupant may have a BLUETOOTH, Wi-Fi, NFC, cellular, etc., based lock on an object on or in the property such as a door, gate, window, garage, attic, room, etc. which uses a mobile device and application to permit or limit access. The web site/server 120 stores a master database of keys which can open the lock.
FIG. 2A illustrates a system signaling diagram of various processes and communication operations during an access operation according to an example embodiment. Referring to FIG. 2A, the diagram 200 includes a communication cycle between the owner device 210, the server 220 and the guest device 230. In operation, the owner device 210 logs onto the management web site hosted by the server 220 and configures a temporary access package 212 for a guest device seeking access to enter the property with a specific appointment and credentials. In another embodiment, the owner device 210 may access an application from the server 220, or another device communicably coupled to the server or the owner device, to configure the temporary access package 212. A user of the device 210 can provide the address of the property so that GPS coordinates, or other location attributes, can be used to set the location of the property. In another embodiment, the device 210, if in or on or proximate the premises, can indicate the location via an action such as turning on a location feature on the device 210.
Security questions that should be answered, or other security actions that should be properly concluded (such as biometric verification, voice verification, visual verification, etc.) are submitted 214 along with a time window for access and a phone number (or other data such as an IP address, etc.) of the guest device 216. This information may be submitted 218 to the server 220 for processing. The parameter ‘LL’ may be used for location. The server 220 permits the owner device 210 to create security questions and answers and/or other security actions for a specific guest. The answer to the question(s) or other security action(s) may be denoted ‘R’. The server 220 permits the owner device 210 to also setup an appointment or appointment window denoted ‘T’. The guest user device 230 will access his/her application and send the serial number, SN′ of the phone (or other identifier) to the server 220. A website, application, service, or program, running on the server 220, or a website, application, service, or program running on the device 210, can send an access or credential package or message 224 to the guest's device 230 which would be running a website, application, service, or program able to receive the message, parse the message and perform an action(s) based on the message. The package or message 224 includes encrypted data 222=Encrypt (K, R.SN), where R.SN is a string (such as a concatenated string) of the challenge response answer and the serial number or other identifier of the device 230. The package 224 is delivered to the guest device 230 and received by an application running on the device. A display (or a speaker) on the guest device 230 provides a message that the premises may be accessed on the given date/time. As a result, on the given date, the device 230 is at or proximate the residence, and if the time of day ‘T’ is within the time window and the device is in the proper location ‘LL’, the challenge question is able to be answered 226. The challenge response is concatenated with the serial number or other identifier of the device 230, as well as a decryption key ‘K’. The response data 228 is sent to the server 220 where the data is stored 231, for example in a user profile. The key ‘K’, will be transmitted over a communication protocol such as Wi-Fi, BLUETOOTH, NFC, cellular, etc., from the guest device 230 (via a transmitter or transceiver, for example) to a receiver or transceiver on the, or communicably coupled to, the door lock which would unlock 232. This key may expire after a certain amount of time or after a certain action is taken (for example, after the lock is unlocked one or more times).
According to example embodiments, a property owner, tenant or other individual prepares an access package via their computing device which will permit a visitor computing device to access the property based on specified conditions being met. The visitor retrieves an access package (which includes an encrypted key) and may proceed to enter the property. The owner can provide a key to guests based on certain conditions being met and using a secure operation. Examples of the various security factors include time of day ‘T’, challenge response ‘R’, serial number of guest's phone, ‘SN’, pre-shared key, ‘K’, and key encryption methods (standard encryption routines).
FIG. 2B illustrates a system signaling diagram of various processes and communication operations during an access operation according to an example embodiment. Referring to FIG. 2B, the example diagram 250 includes the owner device 210 logging into the management web site 252 running on the server 220 (or using an application running on the device 210) to access the server) where he/she may configure a temporary access package for a guest who needs to enter the property with a specific appointment. The owner device 210 provides the address of the property so that GPS coordinates ‘LL’ may be determined and used to ensure the correct guest device. The web site or application permits the owner to create security questions and answers ‘R’ for a specific guest device 230. The web site permits the owner to set up an appointment or appointment window ‘T’ as a necessary variable which must be fulfilled to enter the house.
The server 220 confirms the access package details 254 and the appointment is confirmed by the server 220. The application can then be accessed 256 by the guest device 230 which will send the serial number or other identifier, SN of the phone to the website or application running on the server 220 (or another device communicably coupled to the server or to the guest device 230). The server 220 sends an access package 258 to the guest's smartphone application which consists of, in one embodiment, package=Encrypt (K, R.SN), where R.SN is the concatenated string of the challenge response answer and the serial number of the smartphone. The credentials package is delivered to the application running on the guest device 230, and a message is sent regarding the date/window of time the premises may be accessed. On the given date/time, if the time of day T is within the appointment window and the phone is in the right location, LL (as per the GPS receiver, for example) the user is prompted to answer the challenge question. When the answer is provided, it is concatenated with the serial number of the phone. This concatenation of the serial number and the answer can be used to decrypt the access package and the lock key becomes available. The key K, will be transmitted over a wireless protocol 262 to the lock 240 and the door will open 264. This key may expire after a certain amount of time or after a certain action is taken (for example, after the lock is unlocked one or more times).
Optionally, the configuration may only permit access to the property if a specific guest device (as determined by a device identifier) or if multiple users were present for any lock to open. For instance, if a property owner wants a person to chaperone a guest. This scenario is common with real estate agents and contractors or prospective renters or purchasers who need access to a property. In such a scenario one or more of the following would occur: both devices of both parties would pair with one or more locks in or on the property, both devices would be in the same or similar location, both devices may receive questions or other security actions and both may have a limited time window to access the door lock. Some package access messages do not need to include all of these attributes: ‘T’ (time of day/week), ‘R’ (Challenge question response), SN′ (serial number of guest's phone) and ‘K’ (pre-shared key). For example, ‘T’ can be excluded because one of the devices may already have a record of the time or the ‘smart’ door lock could have a record of the time.
FIG. 2C illustrates a diagram of various processes and communication operations during an access operation according to an example embodiment. Referring to FIG. 2C, the flow diagram 270 includes a set of operations regarding the guest user device attempting to access the wirelessly controlled door lock. For example, the procedure begins 272 with a user device arriving at the door location 274. The current time is analyzed against the authorized time for the user device to access the door 276 and if the current time is within the access time, then the process continues and a location of the guest device is obtained and compared to the location of the door for another comparison operation 278. If the current time is not within the access time, a notification is sent to the guest device. If the guest device is within the location then the device may be prompted with a question(s) and/or other security actions for additional security measures 282. Assuming the correct answer is submitted and/or other security actions are successfully completed 281 then the access package 285 may be decrypted 284 with a known key. If the decryption key fails 286, the door lock will not be unlocked and the door will not be opened 289. However, if the decryption is successful 286 then the door be enabled by a wireless communication signal sent from the guest device to the door lock 287 (for example, via Bluetooth) and the door will open 288.
FIG. 2D includes an example flow diagram 290 of an example method of operation which includes accessing a security application and a security setup procedure 291, transmitting an address location to setup a temporary access 292, transmitting a security question required to be answered prior to access being granted 293, transmitting a time window for the temporary access to be enacted 294, encrypting an access credential comprising the address location, the security question and the time window 295 and transmitting the access credential to a guest device 296 so the guest device can be used to access and open the lock.
FIG. 3 illustrates a user interface of a guest mobile device during an access attempt according to example embodiments. Referring to FIG. 3, the guest user interface 300 includes a date for access to begin 312, a GPS coordinate position of the premises 314, a challenge question 316 and an answer section 318 and a button to access the premises 322. The guest may access the application and enter the property via the wireless communication protocol and the proper credentials.
The above embodiments may be implemented in hardware, in a computer program executed by a processor, in firmware, or in a combination of the above.

Although an exemplary embodiment of at least one of a system, method, and non-transitory computer readable medium has been illustrated in the accompanied drawings and described in the foregoing detailed description, it will be understood that the application is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications, and substitutions as set forth and defined by the following claims. For example, the capabilities of the system of the various figures can be performed by one or more of the modules or components described herein or in a distributed architecture and may include a transmitter, receiver or pair of both. For example, all or part of the functionality performed by the individual modules, may be performed by one or more of these modules. Further, the functionality described herein may be performed at various times and in relation to various events, internal or external to the modules or components. Also, the information sent between various modules can be sent between the modules via at least one of: a data network, the Internet, a voice network, an Internet Protocol network, a wireless device, a wired device and/or via plurality of protocols. Also, the messages sent or received by any of the modules may be sent or received directly and/or via one or more of the other modules.
One skilled in the art will appreciate that a “system” could be embodied as a personal computer, a server, a console, a personal digital assistant (PDA), a cell phone, a tablet computing device, a smartphone or any other suitable computing device, or combination of devices. Presenting the above-described functions as being performed by a “system” is not intended to limit the scope of the present application in any way, but is intended to provide one example of many embodiments. Indeed, methods, systems and apparatuses disclosed herein may be implemented in localized and distributed forms consistent with computing technology.
It should be noted that some of the system features described in this specification have been presented as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom very large scale integration (VLSI) circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices, graphics processing units, or the like.
A module may also be at least partially implemented in software for execution by various types of processors. An identified unit of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions that may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module. Further, modules may be stored on a computer-readable medium, which may be, for instance, a hard disk drive, flash device, random access memory (RAM), tape, or any other such medium used to store data.
Indeed, a module of executable code could be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.
It will be readily understood that the components of the application, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the detailed description of the embodiments is not intended to limit the scope of the application as claimed, but is merely representative of selected embodiments of the application.
One having ordinary skill in the art will readily understand that the above may be practiced with steps in a different order, and/or with hardware elements in configurations that are different than those which are disclosed. Therefore, although the application has been described based upon these preferred embodiments, it would be apparent to those of skill in the art that certain modifications, variations, and alternative constructions would be apparent.
While preferred embodiments of the present application have been described, it is to be understood that the embodiments described are illustrative only and the scope of the application is to be defined solely by the appended claims when considered with a full range of equivalents and modifications (e.g., protocols, hardware devices, software platforms etc.) thereto.
