Title: System for analyzing and attesting physical access

Description:
BACKGROUND 
     The COVID-19 outbreak wreaked havoc on the traditional workplace environment. Entering a workplace could suddenly be deadly for an employee, especially if another employee entered the workplace who had contracted COVID-19. Companies scrambled to provide, where possible, means for employees to work from home while figuring out how to make workplaces safe for employees to return. 
     Some organizations have relied on manual processes, such as setting up a station at entry points to check each employee that enters. However, this solution requires making a few employees be physically near everyone who attempts to access the location, which can put those employees at risk. It also requires significant extra cost and can cause long delays for employees trying to enter the workplace. Also, current access control methods require employees and others to physically touch items or devices when attempting to enter. For example, employees can be required to attest in writing that they have not experienced COVID-19 symptoms, but that requires the touching of pens and the signed paper by multiple individuals, which can further spread the virus. Such a process can also raise privacy issues when one employee is forced to divulge medical information to another. 
     In addition, COVID-19 is just an example of a larger problem—companies do not have adequate systems for restricting physical access based on a dynamic risk assessment of the individual. Employees are typically allowed or denied access without regard to individual risks based on compromised devices, health, or any other risk factor. 
     As a result, a need exists for providing contact-free means for attesting and determining physical access permissions to a location. 
     SUMMARY 
     Examples described herein include systems and methods for analyzing and attesting physical access to a location. In an example, an administrator (“admin”) console can include a graphical user interface (“GUI”) that allows an admin user to create a survey for users in an organization. In one example, the survey can be presented on user devices as a notification. The admin console can send the survey to a server. In one example, the server can include a notification service that manages notifications for the organization. The server can send the notification to user devices according to instructions from the admin console. 
     In an example, a user device for a user can receive the survey and display a notification prompting the user to complete the survey. In one example, the survey and notification can be handled by a management application on the user device. The user can interact with the notification and complete the survey. The user device can send the user&#39;s survey answers to a passport service. The passport service can be responsible for managing physical access rights for users in the organization. In an example, the passport service can also be on a server, but it does not need to be the same server as the notification service. The passport service can determine whether the user should be allowed physical access to a location based on the completed survey. In one example, the passport service can cause a notification to be sent to the user device indicating whether the user can access the location based on the survey response. 
     In an example, the passport service can send the physical access permissions for the user to a physical access control system (“PACS”). The PACS can be system that manages entry and exit to a location, such as a property, building, or room. The PACS can store physical access permissions for users in the organization. When the user attempts to enter a location of the organization, a human interface device (“HID”) at the location can receive credentials from the user, such as a digital access badge. In one example, the HID can communicate with the user device to retrieve the credentials. The HID can query the PACS for the access permissions of the user. The HID can grant or deny access to the user based on the response from the PACS. 
     The examples summarized above can each be incorporated into a non-transitory, computer-readable medium having instructions that, when executed by a processor associated with a computing device, cause the processor to perform the stages described. Additionally, the example methods summarized above can each be implemented in a system including, for example, a memory storage and a computing device having a processor that executes instructions to carry out the stages described. 
     Both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the examples, as claimed.

     DESCRIPTION OF THE EXAMPLES 
     Reference will now be made in detail to the present examples, including examples illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. 
     Methods and systems are described for analyzing and attesting physical access to a location. In an example, an administrator can create a survey for users in an organization. The survey can be sent to user devices as a notification. When a user completes a survey, the user&#39;s device can send the survey answers to a server. The server can analyze the survey answers to determine whether to enable or disable physical access for the user. The server can send the physical access permissions to a PACS. When the user attempts to access a location, the user can provide a digital access badge to an HID at the location. The HID can use the digital access badge to query the PACS for the user&#39;s physical access permissions. The HID can grant or deny access based on the physical access permissions provided by the PACS. 
       FIGS. 1 and 2  are flowchart of examples for analyzing and attesting physical access.  FIG. 3  is a sequence diagram of an example method for analyzing and attesting physical access that includes an admin console, a notification service, a passport service, a PACS, an HID, and a user device.  FIGS. 4A and 4B  are illustrations of an example GUI that an admin can use to create a survey notification.  FIGS. 5A, 5B, 5C, and 5D  are illustrations of an example GUI for a survey notification that can be displayed on a user device.  FIG. 6  is an illustration of an example system for analyzing and attesting physical access. 
       FIG. 1  is a flowchart of an example method for analyzing and attesting physical access. At stage  110 , a server can send a survey to a user device. The server can be a single server or a group of servers, including multiple servers implemented virtually across multiple computing platforms. In one example, the server can be part of a unified endpoint management (“UEM”) system. A UEM system can be a system that manages and secures user devices that are enrolled with an enterprise. 
     In an example, the survey can be received from an admin console. An admin console can be an interface that allows an admin to manage user accounts and configuration settings for an organization, such as a UEM system. The interface can be accessible using an admin account. For example, an admin can log into a computing device and create a survey using an application interface. When the admin finishes creating the survey, the admin console can send the survey to the server. 
     In one example, the survey can be part of an interactive notification, and the server that receives the survey can include a notification service. An interactive notification can be a notification for a user device that allows user interaction. For example, an interactive notification can allow a user to select a button or input text. A notification service can be a service that manages notifications for user devices. For example, the notification service can receive requests to send notifications, determine which user devices should receive a notification, send notifications to user devices, and track when and how users interact with notifications on their user devices. 
     In one example, the survey can include questions that can be used to determine whether a user can have permission to access a physical location. For example, the survey can be used to determine whether a user can enter an office or a secure room of an enterprise. Using COVID-19 as an example, the survey can ask users questions about whether they are experiencing any symptoms of COVID-19 or whether they were exposed to someone they knew had COVID-19. If the user answers yes to any of the questions, the user can be denied physical access to any physical locations of the enterprise. The questionnaire can screen for different health conditions, such as fevers or the flu, and in some examples may not even focus on health questions. Any questions that are relevant to whether a person should have access to a building can be included in a survey. 
     In an example, the survey sent to the user device can be based on a user group that the user belongs to. For example, an organization can assign a unique identity or identifier (“ID”) to its users. When a user enrolls a user device with the organization, the user ID of the user enrolling the user device can be associated with the user device. In one example, the user ID can indicate a group within the organization with which the user is associated. The user ID and group can allow the organization to determine rules and access rights that should apply to the user device. In one example, some groups can identify a physical location, or specific areas of a physical location, where an employee works and may need access to. The organization can create surveys according to location and access levels of users. The server can use the user IDs and group IDs to retrieve the appropriate survey to send to the user device. In one example, the server can identify all users that belong to a particular user group and send a survey to user devices of all users in that group. 
     In an example, the survey sent to the user device can be based on which location the user will attend that day. In one example, the location can be determined based on a group for that location that the user&#39;s ID is assigned to. As an example, at the beginning of the day an application on the user device can prompt the user regarding which office they will be attending that day. Different offices can have different security requirements and different surveys with respect to different users. In another example, an application on the user device can recognize which location the user is currently driving too. The user device can communicate this information to a server, which can respond by sending a survey for the user to fill out once their vehicle has come to a stop. The survey can be tailored to the location and type of user. For example, the user may receive a more elaborate survey if they are not attending their usual office location. Likewise, if the user has recently been out of the office, they may receive a different survey. If the user is an executive, they may receive a different survey than cleaning staff, and so on. The admin server can store user profiles that track where the user typically works, security clearance levels, enterprise group, and other information utilized to select the appropriate survey per user. 
     In still another example, beacons can be physically located next to different building entrances. For example, a BLUETOOTH beacon can be detected by the user device, causing a management application on the user device to download a survey that corresponds to the detected beacon if the user has not already filled out the required survey. A management server can determine whether the user still needs to fill out the survey prior to sending notification of the survey to the user device. 
     In an example, the notification service can send the survey as a notification to multiple devices associated with a user. For example, a UEM system can require that users enroll a user device before the user device can be used with the enterprise system. Among other things, enrolling a user device with the UEM system can include installing a management application on the user device. The management application can configure and enforce compliance and security settings at the user device. If a user device is not compliant, the management application can execute predetermined protocols, such as by denying access to the enterprise network or wiping enterprise data. Enrolling a user device with the UEM system can associate the user device with a profile for the user. In an example, the notification service can send the survey notification to all user devices enrolled under the user&#39;s profile. 
     At stage  120 , the server can receive survey answers from the user device. In an example, once the user completes the survey, the user device can send the survey answers to the server. In one example, the survey answers can be sent from a management application on the user device. In another example, the answers can be sent to a passport service on the server. The server with the passport service can be the same or different from the server that includes the notification service. The passport service can be a service that manages access rights for users and is described in more detail below. 
     In another example, receiving the survey answers can occur serially as the user answers the questions. This can allow for structuring the survey in such a way that additional answers may only be required based on the user&#39;s answers to an initial set of questions. This can help reduce the time it takes for the user to be authorized for access based on their answers, in an example. 
     At stage  130 , the server can determine physical access permissions based on the survey answers. In an example, this stage can be performed by a passport service on the server. In one example, the passport service can analyze survey answers and, based on a set of rules provided by the admin console, determine whether to grant or deny the user physical access rights at a location. 
     As an example, a COVID-19 survey can ask a user if he or she has experienced fever, chills, or shortness of breath, or has been exposed to someone who tested positive for COVID-19 in the past two weeks. If the user answers yes to any such questions, the passport service can disable physical access for the user to his or her office location. In one example, the passport service can disable access for all users until it receives survey answers from the user and the survey answers indicate access should be allowed. In another example, the survey answers can be set to expire after a predetermined amount of time. Continuing the COVID-19 example, the passport service can be configured to disable access for users every day so that the users are required to answer COVID-19 questions each day before going to work. 
     At stage  140 , the server can send instructions to a PACS to update physical access rights for the user. This can be done, for example, using a database query or an application programming interface (“API”) call to the PACS. The instructions can be sent as a data file, in an example. The data file can be an XML, or JSON file, for example. The PACS can be system that manages entry and exit to a location, such as a property, building, or room. This can include managing who can access what location and when. In one example, the PACS can be from a third-party vendor. In an example, the PACS can be part of an electronic access control system that manages entry using human interface devices (“HIDs”) at managed locations. In one example, the HID can be an electronic reader that receives a credential from an object that represents the user. Some examples of such an object can include a radio-frequency identification (“RFID”) card or key fob, biometric data, such as fingerprint, facial recognition, iris recognition, retinal scan, voice, and hand geometry, and a user device. 
     In an example where the credential comes from the user device, the HID can connect to the user device using a wireless communication protocol, such as Near-Field Communication (“NFC”), Bluetooth Low Energy (“BLE”), or ultra-wide band (“UWB”). In one example, the user device can provide a credential to the HID that identifies the user. In another example, the user device can provide a digital key assigned to the user device. In still another example, the user device can also provide a certificate, such as a hash or public key-based credential, that verifies the user device. The HID can check the user ID or digital key with the PACS to determine whether the user can enter the location. 
       FIG. 2  is another flowchart of an example method for analyzing and attesting physical access. At stage  210 , a survey can be created at an admin console. For example, an admin user can create a survey using an interface in an admin console. In one example, survey can be part of an interactive notification. For example, the admin can create a notification that instructs users to take a survey before being allowed physical access to a location. The notification can include a button that, when selected by a user, pulls up the survey questions on the user&#39;s device. 
     At stage  220 , a management server can send the survey to a user device. In one example, the management server can be a notification server that handles sending notifications to user devices. In another example, the questions in the survey and who the survey is sent to can depend on settings or rules selected by the admin at the admin console. For example, users in an organization can have user profiles that include a user ID. User IDs can be associated with various group IDs, which can group users together based on similar characteristics, such as users of the department, office location, or security level. In an example, the admin can select one or more group IDs for a survey to be sent to. In one example, the survey can be sent to all user devices associated with the user IDs of the selected group IDs. 
     As an example, rules and regulations regarding gatherings limits during the COVID-19 pandemic vary by country, state, and even county. Many enterprises have offices and other locations in different states and countries. The local ordinances for an employee going to work in one state can be different for an employee going to work in another. For that reason, an admin can tailor the survey questions based on the employee&#39;s office location. In one example, admin console can include an option to select a location for a survey. Each location can map to a group ID, and the user ID for each employee can also map to the group ID of his or her office. When the admin finishes configuring the survey, the admin console can send the survey to the management server along with the group ID for the selected location. The management server can identify the user IDs associated with the group ID and send the survey to the corresponding user devices. 
     In an example, the user device can include a management application. The management application can include a feature that allows a user to indicate when he or she is planning to access a particular location. For example, an employee traveling to a different office from his primary location can load the management application and indicate the office he plans to access. In response the management server can provide a survey specific to the indicated location. The user can be granted access to that location by the passport service if the user completes the survey and the answers indicate that he should be allowed access. 
     At stage  230 , the management server can receive survey answers from the user device. For example, the user can answer the survey questions on the user device. Upon completing the survey, the user device can send the answers to the management server. Based on the answers to those questions, additional survey questions can be sent or withheld, in an example. 
     In one example, the survey answers can be sent from a management application on the user device. In another example, the answers can be sent to a passport service on the server. The server with the passport service can be the same or different from the server that includes the notification service. The passport service can be a service that manages access rights for users. 
     At stage  240 , the management server can determine physical access rights for the user based on the survey answers. In one example, this stage can be performed by a passport service on the server. In another example, the passport service can analyze survey answers and, based on a set of rules provided by the admin console, determine whether to grant or deny the user physical access rights at a location. 
     In one example, the survey is part of an overall risk score that is calculated for the user. In addition to the survey, the risk score can account for device compliance for devices associated with the user. For example, a management agent on the user&#39;s phone can report that the phone is jailbroken and unencrypted. Based on this device being noncompliant with requirements for the UEM system, the management server can assign a low compliance score to the user. The compliance score can be combined with a survey score to create a risk score. In one example, the admin can determine how much to weigh the survey answers relative to the compliance score in determining the overall risk score. Once determined, the risk score can be compared to an overall threshold required for the physical entrance. Different entrances can have different risk score thresholds. Therefore, the user may be able to enter the office building but not a server room based on their risk score. 
     At stage  250 , the management server can send physical access rights for the user to a PACS. The PACS can manage entry and exit to a location. For example, the PACS can store access rights permissions for users in an organization. In one example, the PACS can be accessible by local access control systems implemented at access points for organization locations. In one example, the local access control system can include an HID that retrieves credentials from a user and a barrier that prevents physical access without approval. As some examples, the physical barrier can be a door with a lock, a turnstile, a parking gate, or an elevator. When a user attempts to access a location, the local access control system can retrieve a digital key or other ID from the user and check it with the PACS to determine whether the user is authorized to access the location. 
     The access rights sent to the PACS can depend on whether the user&#39;s risk score exceeds the threshold for that location. If so, then access rights can be granted. The access rights can also require additional verification at the location, such as facial identification using image recognition. Other second factor authentication may also be required, and the requirement can depend on the risk score, in an example. 
     As an example, at stage  260 , the user device can interact with an HID to request access to a location. For example, the HID can connect to the user device using a wireless communication protocol, such as NFC, BLE, or UWB. The user device can provide a digital key or other identifier to the HID. In one example, the digital key can be stored and managed by a management application. In another example, the user device can also provide a certificate that verifies the user device or stand in front of a camera for facial recognition. 
     At stage  270 , the HID can check for physical access rights for the user with the PACS. For example, the HID can communicate with the PACS, either directly or through an additional device like a local server. The HID can send the digital key and any other ID or credential to the PACS. The PACS can check the digital key against physical access permissions for the user and respond to the HID with whether the user can access the location. The HID can then open the barrier or keep it locked depending on the physical access permissions. 
     In one example where access is denied, the PACS can notify the management server. The management server can send a notification to the user device indicating why entry was denied. In an example where the user has not completed a survey, the management server can send the survey in the notification and indicate that the user must first complete the survey before gaining access. The user can then complete the survey and attempt to access the location again. In another example, the survey can be set to expire after a predetermined amount of time. In an example where a user&#39;s survey has expired, the management server can send a notification to the user device indicating such. In one example, the notification can include a new survey for the user to complete. 
     Continuing the COVID-19 example, an admin can create a COVID-19 survey notification at an admin console. The survey notification can ask users to verify that they have not been in contact with someone with COVID-19 symptoms or tested positive for COVID-19. The admin console can send the survey notification to a notification service. The notification service can send the notification to user devices according to configuration settings provided at the admin console. When a user completes the survey, the user&#39;s device can send the answers to the passport service. The passport service can assess the user&#39;s response to determine whether to enable or disable physical access for the user. The passport service can then send the physical access permissions to the PACS. When the user attempts to gain entry to the location, the user&#39;s device can interact with an HID at the location and provide information identifying the user and verifying the user device, such as a digital access badge and a credential. The HID can query the PACS for the user&#39;s access permissions and send the user ID information. The PACS can authenticate the user device with the credential and check the user&#39;s access permissions. The PACS can then respond to the HID with the access permissions, and the HID can grant or deny the user access based on the PACS response. 
     In an example, of the above described method, the management server can send access permissions to the user device. This can be done in lieu of, or in conjunction with, the management server sending the physical access permission to the PACS at stage  250 . In one example, the management server can provide the physical access permissions to the management application on the user device. The management application can store a digital access badge associated with the user&#39;s ID. Upon receiving the physical access permissions from the management server, the management application can update the digital access badge accordingly. When the user attempts to access a location, the user device can provide the digital access badge, which can include the user ID and the physical access permissions. The HID can grant or deny access based on the physical access permissions provided by the user device. 
     In another example of the above described method, physical access permissions can vary depending on the survey response. For example, instead of a simple grant or denial of complete access, the user can be granted limited access based on the survey response. As an example, a survey can include questions that correspond to different levels or areas of access of a facility. Although the user&#39;s survey response can indicate that the user should be allowed to enter the facility, the response can also indicate that the user should de denied access to certain areas of the facility. Using the COVID-19 survey as an example, a user can be allowed access to a facility if the response indicates that he or she has not experienced any COVID-19 symptoms, the user can be denied access to certain areas of the facility if the response indicates that the user may have come in contact with someone who contracted COVID-19. 
       FIG. 3  is a sequence diagram of an example method for analyzing and attesting physical access. At stage  302 , an administrator can create a survey using the admin console. For example, an admin user can create a survey using an interface in an admin console. In one example, the survey can be part of an interactive notification. For example, the admin can create a notification that instructs users to take a survey before being allowed physical access to a location. The notification can include a button that, when selected by a user, pulls up the survey questions on the user&#39;s device. 
     At stage  304 , the administrator console can send the survey to a notification server. As an example, the admin console can be configured to send the notification to the notification server once the admin user finishes creating the survey. For example, the interface can include a button that the admin can select to indicate that the notification should be sent to the user device prior to the user entering a location. In one example, the admin console can also specify delivery information for the notification. As some examples, delivery information can include which user devices or groups of user devices to send the notification to, whether and when the survey in the notification expires, how long before a user must retake a survey, and criteria when the notification should be sent. The notification can be sent based on a start time or based on a determination that the user is travelling to a particular office, in an example. In one example, the notification simply prompts the user to indicate where they will be attending work today, and separate survey questions can follow based on that answer. 
     At stage  306 , the notification server can send the notification to the user device. In an example, the notification server can send the notification to a management application on the user device. In another example, the notification server can send the notification to a third-party push notification service that then pushes the notification to the user device. 
     At stage  308 , a user can complete the survey on the user device. As an example, the notification can be an interactive notification that includes a button that the user can select to take the survey. The survey can be determined based on which office the user will attend, in an example, which can be stored in the management server as part of a user profile or selected on the user device by the user. Selecting the button to take the survey can cause the survey questions to appear in an interface on the user device. In one example, the button can include a link, such as with a uniform resource locator (“URL”), that directs to a web site with the survey. Selecting the button can cause the user device to access the link and load the web page in a browser on the user device. In another example, the notification can be configured to load the survey questions within the notification itself. At stage  310 , the user device can send the survey answers to a passport service. 
     At stage  312 , the passport service can determine physical access rights for the user based on the survey answers. For example, when the admin creates the survey, the admin can also indicate how the survey questions must be answered for a user to be allowed physical access to a location. As an example, a COVID-19 survey can ask a user if he or she has experienced fever, chills, or shortness of breath, or has been exposed to someone who tested positive for COVID-19 in the past two weeks. If the user answers yes to any such questions, the passport service can disable physical access for the user. If the user answers no to all the questions, the passport service can enable physical access. Alternatively, the answers can result in a positive survey score being combined with other factors, such as device compliance, to yield the total risk score. The risk score can then be compared to a threshold to enable physical access. 
     At stage  314 , the passport service can send a physical access notification for the user to the notification service. For example, the passport service can send a notification to the notification server that indicates whether the user can access the location based on the survey answers. At stage  316 , the notification service can send the physical access notification to the user device. This can inform the user whether he or she can access the location, which can prevent the user from traveling to the location if he knows he cannot enter. In one example, where the user is denied physical access, the notification can include a link or button for taking the survey again. 
     At stage  318 , the passport service can send the physical access rights for the user to a PACS. The PACS can be server or system that manages entry and exit to a location, such as a property, building, or room. As an example, the PACS can store the physical access rights status for each employee in an enterprise. The PACS can update the status according to instructions from the passport service. In an example, the PACS can be part of an electronic access control system that manages entry using HIDs at managed locations. 
     Stages  318  and the combination of stages  314  and  316  can occur simultaneously, in an overlapping fashion, or in a different order. For example, the passport service can send the physical access rights to the PACS before it sends the physical access rights to the notification server. In another example, the passport service can send the physical access rights to the PACS and the notification service simultaneously. 
     At stage  320 , the user device can present an access badge to an HID. The access badge can be a digital access badge, in an example. For example, the digital access badge can include a credential and user ID that can be used to verify the user and determine whether the user has access rights to the location. In some examples, the digital access badge can include a passcode or an RFID card. In one example, the digital access badge can be stored on the user device. When the user approaches the HID, the HID can connect to the user device using a wireless communication protocol, such as NFC, BLE, or UWB. In one example, the user device can include a management application that is responsible for managing the digital access key. In one example, the management application can run in the background of the user device, and when the HID connects to the user device, the management application can handle delivering the digital access key to the HID. 
     At stage  322 , the HID can query the PACS about whether the user is authorized to enter the location. This can be done, for example, using a database query or an API call to the PACS. In an example, the query can include the digital access badge of the employee. In another example, the query can include a user ID for the user. At stage  324 , the PACS can respond to the HID&#39;s query. In an example, the PACS can send a data file, such as an XML, or JSON file, indicating whether the user can access the location or not. 
     At stage  326 , the HID can grant or deny access for the user based on the PACS response. As an example, the HID can control a barrier that prevents physical access without approval. As some examples, the physical barrier can be a door with a lock, a turnstile, a parking gate, or an elevator. If an employee is allowed access to the location, the HID can unlock or remove the barrier. 
     In some examples, when the user attempts to access the location with the user device, the user device can prompt the user for more information if needed. For example, if a user has not yet completed the survey, the user device can alert the user, such as with a tone or vibration, and display a notification that the survey needs to be completed. In another example, the HID can send instructions to the user device to prompt the user for additional information. For example, during the COVID-19 pandemic, some local authorities or employers may require that employees wear facemasks while inside a location. When a user attempts to enter the location, the user device can alert the user and display a notification that asks the employee if he or she is wearing a mask. The user can interact with the notification to indicate that he or she is wearing a mask, such as by selecting a button in the notification that indicates confirmation. The user device can notify the HID, or in some examples the passport service, and the HID can be instructed to grant the user access to the location. 
       FIGS. 4A and 4B  are illustrations of an example graphical user interface (“GUI”) of an admin console used to create a notification with a survey for assessing physical access rights.  FIG. 4A  illustrates a “Content” page  400  that allows an admin user to provide the content of a survey notification. The Content page  400  can include a preview window  401 . The preview window  401  can display how the survey notification will appear on user devices. In one example, the preview window  401  can update in real time as the admin makes changes to the survey notification. In one example, the preview window  401  can be a static window that shows an example survey notification and indicates where each field will be displayed. The Content page  400  can include a “Title” field  402  that allows an admin to name the survey notification and a “Description” field  404  that allows the admin to provide a description of the survey notification. The Title and Description can provide information to users who will fill out the survey. Using COVID-19 as an example, the admin name the survey notification “Return to Work Survey” in the Title field  402  and enter a description in the Description field  404  that reads “All employees must complete this survey regarding COVID-19 before accessing any company offices.” 
     In an example, the Content page  400  can include a “Location” field  406  that allows the admin to enter, or in some examples to select, a location. In one example, information entered into the Location field  406  can be displayed to the admin or user so that they can know for which location the survey applies. In another example, the Location field  406  can allow an admin to select one or multiple locations of an enterprise. In one example, the survey can then be used to allow a user access to all the selected locations. For example, COVID-19 regulations can vary greatly from one place to another. The Location field  406  can allow the admin to create a survey that applies to a set of locations that share similar COVID-19 regulations. 
     In an example, the Content page  400  can include a “Time Zone” field  408 . The Time Zone field  408  can be used to determine the validity and expiration of the survey. The GUI  400  can also include a “Validity Period” field  410 . The Validity Period field  410  can determine how long the survey results are good for. For example, for COVID-19 an enterprise can require that employees complete the survey every day before going to work. The PACS can be configured to reset the physical access rights for employees to disabled after the survey answers expire. In one example, the validity period can begin after the survey is completed. In another example, the validity period can depend on the time zone selected in the “Time Zone” field  408 . For example, the admin can configure all survey answers to expire at the same time regardless of when the survey was completed. As some examples, the survey answers can be set to expire at 12:00 am Eastern Standard Time (“EST”) every night or 1:00 AM every Saturday. 
     In an example, the Content page  400  can include a “Survey” field  412 . The survey field can include an area where the admin can enter the survey questions. In one example, the Survey field  412  can be configured to recognize questions in a certain format. For example, the “Survey” field  412  can instruct the admin to enter each survey question on its own line and as a yes or no question. In one example, a yes or no selection box can be attached to each question when the survey notification is sent to user devices. In another example, the admin can phrase the questions so that they all require the same answer for a user to be given physical access. The survey notification presented on the user device can display all the questions and provide buttons for a user to answer all the questions with a yes or a no. This is described in more detail below regarding  FIG. 5B . 
       FIG. 4B  illustrates an example “Scheduling” page  420  of the GUI that can allow the admin to schedule the survey notification. In an example, the Scheduling page  420  can include a “Expiration Date” field  422  that allows the admin to choose a date when the survey will expire. In one example, the Expiration Date field can include a selectable calendar  424  that allows the admin to select a date. The Scheduling page  420  can also include a time field  426  and a time zone field  428 . These fields can be used to select the time of day, and in which time zone, the survey notification will expire. In an example, the survey notification can reset according to the validity period until the expiration time is reached. 
       FIGS. 5A, 5B, 5C, and 5D  are illustrations of an example GUI for a survey notification on a user device.  FIG. 5A  illustrates an example survey notification  502  that can be displayed on the user device. The survey notification  502  can be displayed in a notification window, in an example. In one example, the survey notification  502  can be a priority notification, and the user device can display it above other non-priority notifications, like notification  506 . In an example, the survey notification can include a survey button  504 . 
     Selecting the survey button can cause the user device to display survey content shown in  FIG. 5B . For example, the survey content can include a “Choose Location” field  510  where an employee can choose a location that he or she plans to visit. In an example where the employee is only allowed access to a single location, the survey content can instead display the location that the survey is for. The survey content can also include survey questions 512, 514, and 516, which can correspond to survey questions provided in Survey field  412  from  FIG. 4A . The survey content can also include an “Agree” button  518  and a “Disagree” button  520 . The Agree button  518  and Disagree button  520  can indicate whether the user agrees with the survey questions. In one example, each of survey questions 512, 514, and 516 can include its own Agree button  518  and Disagree button  520 . 
       FIG. 5C  illustrates an example window that can be displayed if the employee selects the Disagree button  520  or is not granted access based on their survey answers. An access denied window  530  can be displayed to the employee informing the employee that he or she cannot enter the location selected at Choose Location field  510 . In an example, the survey notification  502  can again be displayed in the notification window, along with the survey button  504 . This can allow the employee to retake the survey in case the employee pushed the wrong button or if the employee&#39;s answers change. In one example, the access denied window can be displayed as part of the survey notification  502 . In an alternative example, the access denied window  530  can be a new notification. 
       FIG. 5D  illustrates an example window that can be displayed if the employee selects the Agree button  518  and is granted access based on their survey answers. In an example, the window can include an access approved window  540 . The access approved window  540  can inform the user which office(s) he or she can enter and for when access is allowed. In one example, the access approved window can be displayed as part of the survey notification  502 . In an alternative example, the access approved window  540  can be a new notification. 
       FIG. 6  is an illustration of a system for analyzing and attesting physical access. The system can include an admin console  610 . In an example, the admin console  610  can be an interface that allows an administrator to manage user accounts and configuration settings for an organization, such as UEM system  650 . The interface can be accessible using an admin account. For example, an admin can log into a computing device or application to access the interface. In an example, the interface can include a tool for creating a survey. In one example, the survey can be created as a notification that can be sent out to user devices. 
     When a survey notification is created, the admin console can send it to a notification service  620 . In an example, the notification service  620  can be a service installed on a server in the UEM system  650 . The server can be a single server or a group of servers, including multiple servers implemented virtually across multiple computing platforms. The UEM system  650  can be a system that manages and secures user devices, like user device  630 , that are enrolled with an enterprise. The user device  630  can be one or more processor-based devices, such as a personal computer, tablet, or cell phone. In an example, the user device  630  can include a management application  632 . The management application  632  can communicate with a management server in the UEM system  650  to configure and enforce compliance and security settings at the user device  630 . 
     In an example, the notification service  620  can manage notifications for the UEM system  650 . For example, the notification service  620  can send notifications from various UEM applications and services to user devices. In an example, the notification service  620  can send survey notifications to the user device  630  according to settings configured at the admin console  610 . For example, the admin console  610  can allow an admin to choose which users receive a survey notification, when to send the survey notification, and when the survey notification expires. The notification service  620  can send the survey notification when and as frequently as configured by the admin console  610 . 
     In one example, the management application  632  can manage the survey notification at the user device  630 . For example, the management application can receive the survey notification and cause it to be displayed on the user device  630 . After a user completes the survey, the management application  632  can send the survey answers to a passport service  640 . 
     The passport service  640  can be a service that manages access rights for users and is described in more detail below. In an example, the passport service  640  can be installed on a server in the UEM system  650 . In one example, the passport service  640  can adjust physical access rights for users according to survey answers. For example, the passport service  640  can enable or disable physical access rights for a user depending on the user&#39;s survey answers. In one example, the passport service  640  can disable physical access rights for a user when the user does not answer the survey. For example, when a new notification survey is sent to the user device  630 , the passport service  640  can disable physical access rights for the user until the user completes the survey. 
     In an example, when the passport service  640  enables or disables physical access rights for a user, the passport service  640  can notify a PACS  660 . The PACS  660  can be system that manages entry and exit to a location, such as a property, building, or room. For example, the PACS  660  can include employee badge data  662  and a credential database  664 . The employee badge data  662  can be data that indicates physical access rights for a user. For example, the employee badge data  662  can include the user&#39;s ID and which locations the user is allowed to access. The credential database  664  can include credential information for the user. For example, the credential information can include credential information for authenticating the user device  630  when the user attempts to access a location. 
     As an example, when the user attempts to access a physical location, the user device  630  can interact with a HID  680  at the location. The PACS  660  and HID  680  can make up a building access management system  670  that locally manages physical access. The HID  680  can be an interface device that controls a barrier used to prevent unauthorized physical access to a location. The HID  680  can be configured to receive a user&#39;s digital access badge. As some examples, a user can enter an ID on a keypad, touch a sensor with an RFID card or key fob, or the HID can connect to the user device  630  using a wireless communication protocol like NFC, BLE, or UWB. Where the HID  680  communicates with the user device  630 , the management application  632  can handle a credential exchange with the HID  680 . For example, the management application  632  can provide a digital access badge and credentials that authenticate the user device  630 . The HID  680  can query the PACS  660  to determine whether the user is permitted to access the location. If so, the HID  680  can remove or unlock the barrier.
