The present disclosure relates generally to an access control system (ACS) for a building and more particularly to a smart ACS for a building with frictionless access control. An ACS is a computer-aided and networked system for controlling and monitoring physical access to secured parts of a building or other enclosed area, based on the access credentials and privileges of building users. An ACS may manage groups of buildings in disparate locations and across large campuses. An ACS may use various methods for monitoring, authenticating, and controlling access.
One implementation of the present disclosure is an access control system (ACS) for a building. The ACS includes an access reader, a camera, and an access controller. The access reader is configured to read an access credential provided by a person at an access point of the building and generate ACS data including the access credential. The camera is configured to capture facial recognition system (FRS) data including an image of the person at the access point. The access controller is configured to determine whether the access credential is valid based on the ACS data, determine whether the person is recognized based on the FRS data, grant or deny access to the person through the access point based on whether the access credential is valid and whether the person is recognized, and generate and store one or more of a plurality of access events. Each of the access events corresponds to a different combination of whether the access credential is valid and whether the person is recognized.
In some embodiments, the access controller is configured to identify a first user identity associated with the access credential in response to a determination that the access credential is valid, identify a second user identity associated with the FRS data in response to a determination that the person is recognized, and compare the first user identity with the second user identity to determine whether the first user identity matches the second user identity.
In some embodiments, the access controller is configured to grant access to the person through the access point and generate an “Access Granted” access event in response to a determination that the first user identity matches the second user identity.
In some embodiments, the access controller is configured to deny access to the person through the access point and generate an “Access Denied” access event in response to a determination that the first user identity does not match the second user identity.
In some embodiments, the access controller is configured to determine whether the person is identified as a person of interest by comparing at least one of the ACS data or the FRS data to one or more identifiers identifying people of interest stored in a database. The access controller may generate a “Person of Interest” access event in response to a determination that the person is identified as a person of interest.
In some embodiments, the access controller is configured to generate and send a message including an instruction to dispatch a security officer to a location at which the person of interest is detected in response to the determination that the person is identified as a person of interest. In some embodiments, the access controller is configured to attach the image of the person at the access point to the message to facilitate visual identification of the person of interest by the security officer.
In some embodiments, the access controller is configured to trigger a second level of authentication in response to a determination that the access credential is valid based on the ACS data but the person is not recognized based on the FRS data. In some embodiments, the second level of authentication includes sending the image of the person captured by the camera at the access point to a digital officer, prompting the digital officer to provide a response approving or denying access to the person, and granting or denying access to the person through the access point based on the response provided by the digital officer.
In some embodiments, the digital officer includes at least one of a security officer or another individual familiar with the person. In some embodiments, the access controller is configured to identify a user identity associated with the access credential and select the individual familiar with the person based on the user identity associated with the access credential.
In some embodiments, the access controller is configured to deny access to the person through the access point and generate an “Unknown Person” access event in response to a determination that the person is not recognized based on the FRS data and no access credential is provided by the person at the access point.
In some embodiments, the access controller is configured to classify the person as an unknown person in response to a determination that the person is not recognized based on the FRS data and no access credential is provided by the person at the access point. The access controller may generate and send a message including an instruction to dispatch a security officer to a location at which the unknown person is detected. In some embodiments, access controller is configured to attach the image of the person at the access point to the message to facilitate visual identification of the unknown person by the security officer.
Another implementation of the present disclosure is an access controller for a building. The access controller includes a communications interface configured to receive access control system (ACS) data including an access credential provided by a person at an access point of the building and facial recognition system (FRS) data including an image of the person at the access point. The access controller includes one or more processors and non-transitory computer readable media containing program instructions. When executed by the one or more processors, the instructions cause the one or more processors to perform including determining whether the access credential is valid based on the ACS data, determining whether the person is recognized based on the FRS data, granting or denying access to the person through the access point based on whether the access credential is valid and whether the person is recognized, and generating and storing one or more of a plurality of access events. Each of the access events corresponds to a different combination of whether the access credential is valid and whether the person is recognized.
In some embodiments, the access controller for a building is configured to identify a first user identity associated with the access credential in response to a determination that the access credential is valid, identify a second user identity associated with the FRS data in response to a determination that the person is recognized, and compare the first user identity with the second user identity to determine whether the first user identity matches the second user identity.
In some embodiments, the access controller for a building is configured to determine whether the person is identified as a person of interest by comparing at least one of the ACS data or the FRS data to one or more identifiers identifying people of interest stored in a database. The access controller may generate a “Person of Interest” access event in response to a determination that the person is identified as a person of interest.
In some embodiments, the access controller for a building is configured to trigger a second level of authentication in response to a determination that the access credential is valid based on the ACS data but the person is not recognized based on the FRS data.
Another implementation of the present disclosure is one or more non-transitory computer readable media containing program instructions. When executed by one or more processors, the instructions cause the one or more processors to perform operations including receiving access control system (ACS) data including an access credential provided by a person at an access point of a building and facial recognition system (FRS) data including an image of the person at the access point, determining whether the access credential is valid based on the ACS data, determining whether the person is recognized based on the FRS data, granting or denying access to the person through the access point based on whether the access credential is valid and whether the person is recognized, and generating and storing one or more of a plurality of access events. Each of the access events corresponds to a different combination of whether the access credential is valid and whether the person is recognized.
In some embodiments, the one or more non-transitory computer readable media contains program instructions to perform further operations including identifying a first user identity associated with the access credential in response to a determination that the access credential is valid, identifying a second user identity associated with the FRS data in response to a determination that the person is recognized, and comparing the first user identity with the second user identity to determine whether the first user identity matches the second user identity.
In some embodiments, the one or more non-transitory computer readable media contains program instructions to perform further operations including determining whether the person is identified as a person of interest by comparing at least one of the ACS data or the FRS data to one or more identifiers identifying people of interest stored in a database, and generating a “Person of Interest” access event in response to a determination that the person is identified as a person of interest.
In some embodiments, the one or more non-transitory computer readable media contains program instructions to perform further operations including triggering a second level of authentication in response to a determination that the access credential is valid based on the ACS data but the person is not recognized based on the FRS data.

Access reader module 400 is shown to include a keypad 408 and a microphone/speaker 410. Keypad 408 may be a user input device configured to receive user input such as an alphanumeric PIN, password, or other entry. In various embodiments, keypad 408 may be a physical keypad, a computer graphic presented via display 414, or a projected image. Microphone/speaker 410 can be configured to receive audio from a user (e.g., a voice print) and can provide audio data to access reader module 400 for use in performing audio analytics. Microphone/speaker 410 can also be used to convey audio messages to a user (e.g., intercom communications.
Access reader module 400 is shown to include a pre-classifier 412, and a display 414. Pre-classifier 412 can be configured to correlate input received via other components of access reader module 400 (e.g., image data, audio data, fingerprint data, user input, etc.) with other sensors or electronic devices that provide input to access reader module 400 (e.g., mobile phones, wearable electronic devices, license plate recognition devices, etc.). For example, pre-classifier 412 can use automatic license plate recognition data from a camera in a parking lot to filter a set of people down to a smaller set of people associated with license plates currently in the parking lot. This allows access reader module to search a smaller data set of people when attempting to match the input with stored user attributes or biometrics, which may, for example, allow for decreased latency/increased speed in generating an access decision. Display 414 may include an electronic display screen (e.g., a LCD panel, a LED display screen, etc.) that operates to provide visual feedback to a user.

Access Control System Operation
Referring generally to
A door lock 203 may be opened or closed in response to electrical signals from an associated access controller 201. Access controller 201 can determine whether or not access should be granted to a particular person 210 presenting their access credentials (e.g., an access card) to an access reader module 204. In some embodiments, the determination made by access controller 201 may be based on the access permissions of person 210, which may be stored in an ACS database (e.g., within ACS server 205 or mirror storage 512) and communicated to access controller 201. In some embodiments, the determination made by access controller 201 is based on various parameters or permissions associated with the monitored area. Some users may have access to some areas, but not others. Access controller 201 may grant or deny access based on the time of day or week and may restrict access during public holidays. ACS server 500 or access controller 201 can be configured to processes access requests in accordance with such rules.
Access reader module 204 can be configured to read the credentials of person 210 (e.g., from an access card) and pass the data to access controller 201. Access controller 201 may pass the credential data to ACS server 500 via a communications network. ACS server 500 can compare the credential data with credential data stored in credential manager 506 and can make a determination as to whether the credentials are valid. ACS server 500 may communicate either a positive or negative response to access controller 201. Access controller 201 may then either grant access (by causing door lock 203 to open) or deny access. In some embodiments, access reader module 204 may include a user interface for communicating the outcome of the decision (e.g., grant access or deny access) via a display screen, lighting element, and/or audible signals.
In some embodiments, the decision to grant or deny access and the resulting action performed by access controller 201 (e.g., unlocking door look 203 or keeping door lock 203 locked) is logged in ACS server 500 as an access event for monitoring and reporting. In instances where an invalid access attempt is made (e.g., a user with insufficient privileges requests access using an access card), access controller 201 may not cause door 202 to be unlocked and may indicate an invalid access attempt. Access controller 201 may then send event data to ACS server 500 recording this event. The event data associated with the access event may include the ID of the cardholder (e.g., person 210), the ID of door 202, the time of the event, the reason for denial of access, and/or other parameters or attributes of the access event.
One example of an access event is an “Access Granted” (AG) event, which may occur when a valid user with sufficient privileges is granted access. Another example of an access event is an “Access Denied” (AD) event, which may occur when a valid user without sufficient privileges is denied access. Another example of an access event is a “Door Forced Open” (DFO) event, which may occur a door was opened without the use of valid access credentials (e.g., door 202 is manually forced open by person 210 without access controller 201 first granting access). Another example of an access event is a “Door Held Open” (DHO) event, which may occur when a door has been held or kept open for longer than a predetermined amount of time. Another example of an access event is a “Door Malfunction” (DM) event, which may occur when a physical or logical failure occurs in some part of ACS 200 associated with a particular door 202 (e.g., a failure of door lock 203 to properly open when requested by access controller 201). Another example of an access event is a “Person of Interest” (POI) notification, which may occur when the person 210 detected by ACS 200 is flagged as a person of interest. Another example of an access event is an “Unknown Person” (UP) notification, which may occur when the person 210 detected by ACS 200 is unable to be identified. Another example of an access event is a “Tailgating” or anti-passback notification, which may occur when multiple people pass through the door 202 or other access point, but only one of the people presents a valid access credential.
The data collected by ACS 200 and/or ACS server 500 may be used to generate reports and may be further processed to generate insights into door use or other security matters. Such reports and/or data may be displayed on a user interface for system monitors. Analysis of door use data may focus on types and times of event, specific doors, specific users etc. ACS 200 may interact with a video security surveillance system. For example, if there is a DFO event for a particular door 202, ACS 200 may attach a video recording of that door 202 at the time of the DFO event and associate it with an alarm event.
Access Control with Facial Recognition
In some embodiments, ACS 200 uses a facial recognition system (FRS) to authorize user access to a door 202. A FRS may use a person's unique facial features, such as the shape of their face, as an access credential to identify and authenticate the person's access to a controlled area. Such facial recognition data can be captured be cameras or other facial recognition devices located at the access point. In some embodiments, the FRS uses input from a variety of different sensors or devices to augment the facial image data. Examples of such devices include audio sensors, wearable devices, mobile devices, and the like. The FRS may use input from a license plate recognition system to determine which people have arrived at the building and may use input from a location tracking system to determine the locations of various people in the building. For example, the FRS can detect each person's mobile device or license plate and may only search for those people's facial data in the FRS database. ACS 200 can use FRS data to derive actionable insights into a building's security environment and risk profile. Access control data (e.g., card scan data, user-entered passwords or PIN numbers, biometric data, etc.) can be combined and correlated with FRS data and/or other data to enhance the overall security of a monitored system. In addition, access control data and FRS data can be used to improve on existing risk management workflows and decisions.
In some embodiments, ACS 200 uses a combination of access control data and FRS data to recognize, verify, and/or authenticate a person's identity. Access control data can be collected when a person 210 scans an access card at an access reader module 204. Access reader module 204 can read a card ID from the access card and provide the card ID to access controller 201. FRS data can be collected by a camera located nearby access reader module 204 and configured to capture an image of the person's face. The FRS data can be provided to access controller 201 or ACS server 500 and analyzed by access controller 201 or ACS server 500 to determine whether the FRS data matches the profile of any person recognized by access controller 201 or ACS server 500.
In some embodiments, ACS 200 (e.g., ACS controller 201 or ACS server 500) uses a combination of ACS data (e.g., card scan data) and FRS data (e.g., facial recognition results, license plate recognition data, mobile device detection data, etc.) to trigger automated workflows and derive security insights. The combination of ACS data and FRS data can contribute to a more contextual and situationally aware risk analysis of a site environment. In some embodiments, ACS data and FRS data may be used in conjunction with other data for risk scoring by a risk analysis engine (described in greater detail below).
In some instances, the ACS data may indicate that a person 210 has scanned a valid card (e.g., a card belonging to a person recognized by ACS 200) at an access reader module 204 and may include the card ID or user ID associated with the valid card. If the card is valid, the ACS data may also indicate whether the person 210 associated with the valid card (e.g., “John Smith,” “User ID 123,” etc.) has permission to access the space controlled by the access reader module 204 at which the access card was scanned. In other instances, the ACS data may indicate that the person 210 has scanned an invalid card (e.g., a card that has been deactivated or was never associated with ACS 200). If the card is invalid, the ACS data may indicate that the access card or person 210 who scanned the invalid card was not recognized by access reader module 204.
In some instances, the FRS data may indicate that facial recognition was successful (i.e., the visual appearance of person 210 matches a facial profile stored by ACS 200) and may include the user ID associated with the recognized person 210. If person 210 is recognized, the FRS data may also indicate whether the recognized person 210 (e.g., “John Smith,” “User ID 123,” etc.) is a person of interest (POI). In other instances, the FRS data may indicate that facial recognition was unsuccessful (i.e., the visual appearance of person 210 does not match a facial profile stored by ACS 200) and therefore person 210 is unrecognized. ACS 200 can be configured to compare the ACS data with the FRS data to determine whether both the ACS data and the FRS data identify the same person 210 (i.e., whether the ACS data and FRS data match).
ACS 200 can create various types of access events (and may grant or deny access to the controlled space) based on the correlation between the ACS data and the FRS data. Table 1 below outlines several scenarios A-F that may occur and how each scenario may be identified by ACS 200 based on the correlation between the ACS data and the FRS data. Table 1 also identifies the type of access event created by ACS 200 for each scenario.
Scenario A may occur when the FRS data indicates that facial recognition was successful, the ACS data indicates that the card presented by person 210 is valid, and ACS 200 determines that both the FRS data and the ACS data identify the same person. In scenario A, ACS 200 may determine whether the identified person is permitted to access the controlled space. If the person is permitted to access the controlled space, ACS 200 may grant access and create an “Access Granted” event. However, if the person is not permitted to access the controlled space, ACS 200 may deny access and create an “Access Denied” event.
Scenario B may occur when the FRS data indicates that facial recognition was successful, the ACS data indicates that the card presented by person 210 is valid, but ACS 200 determines that both the FRS data and the ACS data do not match (i.e., the FRS data and the ACS data identify different people). This may occur when a first person presents a second person's access card at an access reader module 204. In scenario B, ACS 200 may deny access and may create a “False Positive” and/or “Access Denied” event. In some embodiments, ACS 200 sends an automated message to the second person (e.g., via email or SMS) to alert the second person that his or her access card was scanned by the first person. ACS 200 may also send such an automated message to a security officer.
Scenario C may occur when the FRS data indicates that facial recognition was successful but the ACS data indicates that the card presented by person 210 is invalid. If the person 210 recognized by the FRS data is a person of interest (POI), ACS 200 may deny access and create an “Access Denied” and/or “Person of Interest” event. In some embodiments, ACS 200 sends an automated message to a security officer alerting the security officer of the person of interest.
Scenario D may occur when the FRS data indicates that facial recognition was unsuccessful but the ACS data indicates that the card presented by person 210 is valid. This may occur when a person's appearance has changed or is not recognized (e.g., new haircut, sunglasses, wearing a hat, blurred image) even though the person 210 has presented a valid access card. In scenario D, ACS 200 may trigger a second level of authentication in order to confirm the identity of the person 210. For example, ACS 200 may send an automated message to a security officer or other individual who is familiar with the person 210 (i.e., a digital officer) associated with the valid access card. The automated message may include an image of person 210 captured by a camera at the time the access card was validated. The digital officer can reply to the message (e.g., with “Approve” or “Deny”) in order to grant or deny access. If the second level of authentication is successful (e.g., an “Approve” reply is received), ACS 200 may grant access and create an “Access Granted” event and a “False Negative” event. ACS 200 may also use the FRS data to update the stored appearance of the person 210 so that future facial recognition attempts will be successful, given the new or changed appearance of person 210. However, if the second level of authentication is unsuccessful (e.g., a “Deny” reply is received), ACS 200 may deny access and create an “Access Denied” event.
Scenario E may occur when the FRS data indicates that facial recognition was unsuccessful and the ACS data indicates that the card presented by person 210 is invalid (or no card was presented by person 210). Scenario E may occur when person 210 is an unknown person who is not authorized to access the building. In scenario E, ACS 200 may deny access and create an “Access Denied” event. In some embodiments, ACS 200 sends an automated message to a security officer or establishes a communications link with the security officer (e.g., via an intercom at the point of entry) who can determine whether access should be granted or denied to person 210. If the security officer determines that person 210 should be allowed entry, ACS 200 may grant access and create an “Access Granted” event. However, if the security officer determines that person 210 should be denied entry, ACS 200 may deny access and create an “Access Denied” event.
Scenario F may occur when the FRS data indicates that facial recognition was successful and the ACS data indicates that the card presented by person 210 is valid, but the recognized person 210 is flagged as a person of interest. In scenario F, ACS 200 may deny access and create an “Access Denied” and/or “Person of Interest” event. In some embodiments, ACS 200 sends an automated message to a security officer alerting the security officer of the person of interest.
In some embodiments, ACS 200 includes a complex event processing engine and/or a risk analysis engine, which can be used by ACS 200 to automatically generate risk-scored alert types for improved real-time security and site management. Examples of such an event processing engine and/or a risk analysis engine are described in detail in U.S. Provisional Patent Application No. 62/627,698 filed Feb. 7, 2018, and U.S. Provisional Patent Application No. 62/627,677 filed Feb. 7, 2018. The entire disclosures of both these patent applications are incorporated by reference herein.
In some embodiments, ACS 200 provides information that can be used to calculate risk for a building or other entities associated therewith (e.g., people in the building, equipment in the building, etc.). For example, ACS 200 may create a loitering event in response to detecting an unknown person at a door for a predetermined amount of time (e.g., scenario E). Based on situational information about the loitering event (e.g., time of day, frequency of recurrence, etc.), ACS 200 may cause the risk score of the building to be adjusted to reflect potential changes in the vicinity. As another example, ACS 200 can detect patterns of anomalies such as a cluster of false positive events (e.g., scenario B) which may indicate systemic issues with ACS 200 (e.g., card readers malfunctioning, database errors, etc.). As another example, ACS 200 can detect patterns of false negative events (e.g., scenario D), which may indicate that a camera used to capture the FRS data is malfunctioning or has been tampered with.
In some embodiments, ACS 200 is configured to receive input from a risk analysis engine such as that disclosed in U.S. Provisional Patent Application No. 62/627,698 filed Feb. 7, 2018. For example, ACS 200 may receive a risk score for the building in which ACS 200 is located. The risk score may impact or alter the standard operating procedures (SOPs) triggered in one or more of scenarios A-F. For example, if the risk engine has updated the building's risk score to a high level, the SOP for a false positive event (e.g., scenario D) may be changed by ACS 200 to automatically deny such access attempts.
Referring now to
While the aforementioned embodiments refer specifically to facial recognition, it should be understood that, in various implementations, one or more other types of biometric data can be used instead of or in addition to facial recognition data. For example, in various implementations of the aforementioned systems and methods, different biometric data such as fingerprint data, hand or other body geometry biometric data, retina scan data, iris scan data, signature analysis data, voice analysis data, DNA data, typing recognition data, walking gait analysis data, and/or any other type of biometric data may be utilized. In one particular example, the FRS data discussed above could be replaced with fingerprint data, such that access control decisions and workflows discussed above could be performed using the ACS data in conjunction with analysis of fingerprint data obtained from a fingerprint scanner. In another example, the FRS data could be supplemented with fingerprint data, such that access control decisions are made in consideration of all three of facial recognition data, fingerprint data, and ACS data (e.g., card reader data); for example, access may be granted automatically only if the user is identified by all three methods and the three identities match.
The construction and arrangement of the systems and methods as shown in the various exemplary embodiments are illustrative only. Although only a few embodiments have been described in detail in this disclosure, many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.). For example, the position of elements can be reversed or otherwise varied and the nature or number of discrete elements or positions can be altered or varied. Accordingly, all such modifications are intended to be included within the scope of the present disclosure. The order or sequence of any process or method steps can be varied or re-sequenced according to alternative embodiments. Other substitutions, modifications, changes, and omissions can be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present disclosure.
The present disclosure contemplates methods, systems and program products on any machine-readable media for accomplishing various operations. The embodiments of the present disclosure can be implemented using existing computer processors, or by a special purpose computer processor for an appropriate system, incorporated for this or another purpose, or by a hardwired system. Embodiments within the scope of the present disclosure include program products comprising machine-readable media for carrying or having machine-executable instructions or data structures stored thereon. Such machine-readable media can be any available media that can be accessed by a general purpose or special purpose computer or other machine with a processor. By way of example, such machine-readable media can comprise RAM, ROM, EPROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code in the form of machine-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer or other machine with a processor. Combinations of the above are also included within the scope of machine-readable media. Machine-executable instructions include, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing machines to perform a certain function or group of functions.
Although the figures show a specific order of method steps, the order of the steps may differ from what is depicted. Also two or more steps can be performed concurrently or with partial concurrence. Such variation will depend on the software and hardware systems chosen and on designer choice. All such variations are within the scope of the disclosure. Likewise, software implementations could be accomplished with standard programming techniques with rule based logic and other logic to accomplish the various connection steps, processing steps, comparison steps and decision steps.
