RELATED APPLICATION
This application claims the benefit of priority under 35 USC 119(e) of U.S. Provisional Patent Application No. 62/195,346 filed Jul. 22, 2015, the contents of which are incorporated herein by reference in their entirety.


FIELD AND BACKGROUND OF THE INVENTION
The present invention, in some embodiments thereof, relates to control access gates and, more specifically, but not exclusively, to centralized gate access control.
Security systems for controlling accesses to a restricted area are very common today. Apartment complexes, gated communities, individual residences, office complexes and research facilities often have these systems. At a minimum they consist of security gate at an entrance.
Over the years, these systems have become quite sophisticated and consist of systems controlled by computers. In larger systems this can include a primary computer located at a central control office that connects through local telephone lines or a separate private communication system to the gate controller units at several gated access entry locations around the restricted area. The local unit at each gated entry has its own computer controlled system. The local system at each gate will typically have saved in computer memory various access codes that occupants of the secure area can enter by keypad, transponder or otherwise to open the gate and gain access. The local units at each gate will typically have a communication unit that includes a display and directory of occupants so an individual arriving at the gate can contact a party in the restricted area and thereby gain entry. These systems typically have diagnostic systems that allow the central control office to monitor operation of the local units and diagnose operational problems at the local unit.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION
The present invention, in some embodiments thereof, relates to control access gates and, more specifically, but not exclusively, to centralized gate access control.
According to some embodiments of the present invention, there is provided a server based solution to manage access of users to various locations by controlling gate control units which are added to control a plurality of access gates (e.g. distributed in various geographical locations) according to centrally managed user credentials.
The gate control units may be added to existing access gates, for instance by an integration that allows controlling the access gates based on the reading of a proximate barcode (e.g. quick response (QR) code), for instance from a display of a mobile device and/or a wireless signal (e.g. NFC signal, Bluetooth message, and/or Wi-Fi message). In use, a gate control unit extracts a unique identifier of a user, forward the unique identifier to a central service or to a local match with local data, and receives a command to operate one or more access gates accordingly. The communication with the central service, where needed, may be secured, for instance using a cryptographic hash function. The local data may be updated when a new access code is added. In such embodiments, remote access to the central unit may be performed only when a valid access token or credentials cannot be found for the user identifier.
Optionally, the cloud computing solution integrates location based advertising solutions, allowing sending the user promotional content based on his request to access a certain location. Additionally or alternatively, the cloud computing solution integrates location based billing solutions, allowing the user to pay securely for services which are provided in the certain location, for example for access or parking. The billing and/or advertisement may be performed based on information extracted from user profiles which are centrally managed by one or more servers.
According to some embodiments of the present invention, user interface that allows operators to update user profiles may be updated in real time, either centrally and/or distributable in local database at the access gate level. For instance a user profile of a visitor may be added to the system, for example by providing a contact details (e.g. user email, cellular number, and ‘personal identification number) and a visiting period. In use, a user profile record is created with a user identifier, allowed areas definitions (e.g. which access gates should be open for the user) and a visiting period, for instance time and day. The allowed areas may be deduced from the credentials of the operator and/or inputted manually by the operator. The system may forward to the visitor (using the contact details) a barcode that is generated according to the user identifier and/or a message indicating that he or she can use a client application to access the respective location. Upon arrival at the respective access gate, the user can present the barcode, for instance on the screen of his mobile device, or operating an application to transmit an NFC signal, allowing a reader of the gate control unit to extract an encoded user identifier. The user identifier may be locally matched against data in a local database for authentication and/or forwarded to a central server for authentication using the respective user profile. The user profile may be updated by the operator. Optionally a log of the given credentials and access requests is kept per user.
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples.

It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
Reference is now made to FIG. 1, which is a schematic illustration of a method of managing access credentials of a plurality of users to a plurality of different and separated areas by using a plurality of gate control units to control various access control gates such as car gates and pedestrian gates based on readings from reader(s), according to some embodiments of the present invention. The method 100 allows centrally controlling a plurality of control units based on rules and/or events which are updated in a user profile of a user (e.g. a visitor, a worker and/or a tenant) and to log activity of the user for various usages (including billing and advertisement). The method provide a technical solution to the problem of managing a plurality of access gates optionally of various types and locations using a central management server, optionally based on rules and user profiles which are updated by one or more operators who use management graphical user interfaces. It should be noted that the control of the access gates can be used for parking garage identification and payments, tickets requisitions, and location based messaging system and monitoring as described below.
Reference is now also made to FIG. 2, which is a schematic illustration of a system 200 adapted to manage the access of user to various areas, for instance by implementing the method depicted in FIG. 1, according to some embodiments of the present invention. The system 200 based on a central unit 201 executed on one or more servers or virtual machines and connected to a network, such as the internet. The central unit 201 includes one or more processors 207 which execute a code of a managing module 206 and have access to one or more databases which are either locally or remotely installed as depicted in 205, 206, and 227. The database(s) 205, 206 stores user profile(s) defining user identifiers (e.g. number, phone number, email address, car plate, worker ID number, tenant number and/or the like) at least access right (credentials) of different users to access different areas optionally in different times and/or access rules for applying the user profile(s), for example billing rules, advertisement rules and/or the like. The database(s) 205, 206 optionally stores logs recording access (and optionally trials to access) of users, for instance as part of the user profiles. Local databases 227 may store user profiles (or portions thereof) of users who are granted with credentials to pass via the respective access gates.
Optionally, the system 200 further includes a gate manager module 208, for instance a software, either locally installed or accessed via a browser, which the code thereof is executed by processors 209 of a client terminal 210, such as a desktop, a laptop or a Smartphone, so as to allow a system operator to use the client terminal for updating and/or creating user profiles. The gate manager module 208 may communicate with local or remote databases 205, 206, and 227.
In use, after an access permit is update for a user, a message may be forwarded to the user from the system 200. The message may include a user identifier or an encoded ticket which is associated with the user identifier, for instance a barcode image or a code for inputting into a signal such as an RFID signal or a Wi-Fi signal. The message may be forwarded to an application installed in a mobile device of the user, for example 2017. The message may be forwarded as a Short Message Service (SMS) message or a Multimedia Messaging Service (MMS) with a link to download the image with a generated barcode or the application 217 and/or to a registration webpage for allowing the user to provide his details and optionally to see information about the permit.
The system 200 further includes a plurality of access gate control units 211 which are adapted to communicate with the central unit 201 via the network 205 for opening and closing one or more access gates based on user identifier (or a ticket encoding the user identifier) extracted using a reader 204 and processed based on a code of a gate manager module 202 which is executed using processor(s) 203. The reader 204 may include an imager, such as a camera or an image sensor, such as a Complementary Metal Oxide Semiconductor (CMOS) sensor for imaging a machine readable code, such as a barcode, for instance a QR code that may be generated and/or displayed using a locally installed application. The reader 204 may include a wireless signal reader, such as a BluetoothTM reader, an NFC reader, and/or a Wi-Fi reader to identify proximity of user by extracting a user identifier (or a ticket encoding the user identifier) from a signal transmitted by a mobile device of a user. Optionally, the gate control unit 211 has a housing that comprises the processors and the reader and optionally connected wirelessly or via wire to the control of the controlled gate(s).
Optionally, the reader comprises a barcode reader, for instance infrared (IR) reader. Optionally, the reader is an image sensor and the unique identity is extracted from a facial image of a user, for instance using a face recognition algorithm that allows extracting biometric features of the user and to match the biometric features with stored biometric features in the memory. Optionally, the reader is a fingertip reader and the unique identity is extracted from fingertip data of a user, for instance using a fingertip recognition algorithm that allows extracting biometric features of the user and to match the biometric features with stored biometric features in the memory.
Optionally, an access gate control unit 211 is an add-on hardware unit which is adapted to communicate with an existing access gate and to instruct the existing access gate to open or close by sending an open and/or close control signals. For example, reference is now also made to FIG. 3 which is an exemplary schematic illustration of communication between an exemplary gate control unit 211 that is implemented as an add-on and existing electric gate between the exemplary gate control unit 211 and the central unit 201 which is implemented by a cloud server, according to some embodiments of the present invention. The access gate control unit 211 optionally includes a microcomputer, such as a microprocessor, and a network interface adapted to communicate with the central unit 201. Optionally, the gate control unit 211 includes memory for storing the code of the gate manager module 202 and/or respective data. The memory may be a memory card, such as a secure digital (SD) card. Optionally, the gate control unit 211 has a power source connection and optionally a backup source, such as a lithium battery pack to avoid failure during power outage. Optionally, the gate control unit 211 a communication array consisting of a Wi-Fi chip, a Global System for Mobile Communications (GSM) mobile broadband internet modem, a Bluetooth chip, a Radio Frequency Identification (RFID) chip and/or NFC chip and optionally a relay controller.
In use, the access gate control unit 211 uses a reader to read a user identifier, for example from a signal transmitted by a mobile device 302 or a displayed code on a display of the mobile device 302 (e.g. as described above) and to locally match the user identifier with local data for authentication and/or forward the user identifier (or a ticket encoding the user identifier), optionally encrypted by a cryptographic hash function, such as a MD5 message-digest algorithm, to the central unit 201. For brevity, a user identifier or any ticket associated or encoding the user identifier are referred to herein as a user identifier. Optionally, the user identifier is forwarded to the central unit 201 only when no local match is found. The message to the central unit 201 may be encoded and include details about the address of the access gate, for instance a building number, an ID of an entity issuing the permit as acquired from the application 217, an access point ID, a Unix timestamp representing the time when the permit becomes active as acquired from the application 217, a Unix timestamp representing the time when the permit becomes inactive as acquired from the application 217, and/or a Unix timestamp representing the time the user generated the code on his mobile device as acquired from the application 217. Optionally, the local databases 227 are updated with user identifiers and credentials of users who are designated to pass via the respective access gates. In such a manner, latency of communication with the central unit 201 in real time can be saved. Moreover, the access gates remain operative in real time. Clearly local data has to be dynamically updated in real time to reflect recent changes. Such updating may be performed continuously or upon an update at the central unit 201. Additionally or alternatively, the user profile records are distributed to be stored in local databases to avoid storage redundancy while reducing latency.
Optionally, a sequence of words or other text, referred to herein a passphrase, is used by access gate control unit 211 to control access to the central unit 201, for example for marking the message with the user identifier as valid. The central unit 201 matches the user identifier, optionally after decryption, with a user profile to determine whether the specific user has a permit to enter an area protected by the gate(s) controlled by the access gate control unit 211, optionally at the current date and time. Optionally, a passphrase is used by the central unit 201 to encode the response to the access gate control unit 211. It should be noted that the access gate control units 211 may be distributed to control various access gates to various area, for instance areas in different buildings, streets, cities or even countries.
Reference is made, once again, to FIG. 1 which depicts actions made at the central unit 201 at the left side and actions made by the access gate control unit 211 at the right side. As depicted in 101 a plurality of user profiles are stored for example in databases 205 and 206 as described above. The plurality of user profiles are optimally generated by the operator module 208 during a process wherein access permits are given to users. Optionally, information about the access permits and the respective user identifiers are distributed to the users via applications messages and/or SMS as described above.
In one example, when an access permit is updated in a user profile of a registered user which downloaded the client module 217 to his device, a notification is sent to the client module 217 to notify the user of the new access permit. When an access permit is updated in a user profile of a new user which is not a registered user of the system, a message is sent to an address of the user (address provided by the operator via the operator module, for example a phone number or an email) using an SMS messaging unit that notify him he has a new permit and sends him to download the app. After the user downloads the client module 217 the user may enter identification details such as personal ID and a mobile phone number (or confirmation of a mobile phone number). After the data is verified by the system 200 a pin code may be sent to the user by SMS to verify the ownership of the mobile device.
As shown at 102, when the access gate control unit 211 identifies a user identifier, for instance based on reader's reading the user identifier is wirelessly forwarded to the central unit, for instance in a format of an access query, as depicted in 103. Optionally, the central unit checks the internet protocol (IP) address of the sender of the message to see if it is originated from any member of a white list of authorized IP addresses.
As shown at 104, the central unit 201 identifies that matching user profile and determines an access permit or denial accordingly. For example, a user identifier or a user identifier ticket issued to the user, such as a number, is extracted from a barcode issued for the user, either in advance or using an application upon request.
The number is locally matched for entry authentication, for example as described herein for the central unit 201 or forwarded to the central unit 201 that identifies accordingly the user profile of the respective user and extracts from the user profile whether the user has credentials to access an area kept by the gate controlled by the access gate control unit 211 of the reader which was used to read the barcode issued for the user. A response that includes the access permit or denial is sent back to the access gate control unit 211, as shown at 105. As shown at 106, based on the response, the access gate control unit 211 sends (or does not send) control signal(s) to operate one or more access gates. Optionally, this action also send a ping to the central unit 201 for logging that the gate has been open, for instance for logging an entrance or an exit based on the current location ID of the access gate control unit 211.
According to some embodiments of the present invention, the operator module 208 allows an operator, such as an office, to manage credentials of visitors and users such as workers and optionally to access user logs documenting actual accesses to facilitates, for instance as a time clock.
Optionally, operator module 208 comprises a graphical user interface (GUI) which may be locally generated by a local process or rendered by a browser based on instructions from the central unit 201. The credentials may be updated in real time.
Optionally, alerts may be generated when a presence of a user in an area does not match his or her credentials, for instance when a visitor remains after defined visiting hours. Optionally, alerts may be generated when a lack of presence of a user in an area does not match his or her credentials, for instance when a worker does not arrive to work and/or leave before the end of a shift. Optionally, the operator module 208 is designed to allow an operator to save their contact book for fast credentials management of employees, visitors, clients and/or the like. Optionally, the operator module 208 is designed to allow an operator to grant a permanent access permit or a time limited access permit. Optionally, the operator module 208 is designed to allow an operator to generate reports with analytics data, as the ability to show which permits were issued, which were used and extended.
Optionally, an administrator module (not shown) is provided and set to allow an administrator to monitor operator modules 208, set restrictions and rules, provide insights on general usage schemes, and find unauthorized usage of the operator modules 208. The administrator module is connected to the operator modules 208 and to the central unit 201 via the network 205.
According to some embodiments of the present invention, as depicted by references, client modules 217 installed in mobile devices, such as 218, allows the central unit 201 to communicate with the users. The client modules 217, for instance applications, such as Android, iOS, Windows Phone, Blackberry OS and/or FireOS applications, are installed on mobile devices such as Smartphones, Smartwatches and tablets and receive messages from the central unit 201, optionally based on the unique identifier of the respective user as extracted from the user profile. The client modules 217 may be used for displaying active access permits given to the user. The client modules 217 may be used as a single pass for multiple locations, for example by transmitting signals and/or displaying barcodes with the user identifier or a ticket that is based on the user identifier. Optionally, the client modules 217 alert the user when an access permit is about to expire and give them the option to send a message to the operator to extend the permit duration.
The client modules 217 may be used as a platform for distributing additional data. For example, promotional content may be sent to the users who are access gate control unit 211 using the client modules 217, for example coupons, advertisements and/or the like. Additionally or alternatively, the client modules 217 allow presenting the users with billing information and to establish a GUI session therewith to complete or approve a charge or a payment. Optionally, billing data and/or promotional content is sent when the user complies with certain terms, for instance enter in an access gate at a certain time and/or with certain people and/or based on access grant given by a certain operator, for example a law firm, a dentist and/or the like.
Optionally, a client module 217 includes a permit GUI to allow the user to see which permits are currently active for him (for example with addresses, gate location, and/or timing) and optionally to request for permit renewals by a click of a button. Optionally navigation button and/or call buttons are added to allow the user to initiate a navigation session or a call by a click of a button.
The methods as described above are used in the fabrication of integrated circuit chips.
