Definitions
- the present invention is related to an access control system and a method thereof, and especially to an access control system and method thereof comprising an access application program enabling a smart phone to function as an access card of the access control system.
- Access control of employees and visitors entering residential areas and/or buildings is common.
- the access policy can be only to count the number of people moving in and out of the building, for example if the "company" is an open and free museum. If entrance to for example the museum requires payment of tickets, the access control is just a check of valid tickets.
- access control may require a security level identifying people that are authorized and authenticated to be allowed to enter the research facility, for example to prevent theft of sensitive research data, and also restricting access only to people that are qualified to handle for example dangerous materials (radioactive material, microorganisms etc.).
- a common access control method is to issue access cards for example comprising information identifying the carrier of the card as an employee having a certain access level to the building.
- the card is used at access card terminals located besides doors, and when a valid access card is read at the door terminal (via for example NFC communication) the door is opened.
- Visitors usually makes an approach to a reception area, wherein a receptionist makes a call to a contact person the visitor is informed to contact when arriving.
- the contact person can then come to the reception area and guide the person inside the building to for example a meeting room, or the contact person authorize the receptionist to print out an access card to the visitor.
- Such visitor cards are usually valid only for a limited time (i.e. the duration of the visit).
- Loss of an access card can be a problem. Therefore, further methods of enhancing the protection against misuse of lost access cards is common. For example, access cards used at door terminals can be qualified with a secret PIN code entered into the door terminal via a keypad.
- Terminals may be configured to read out the identification information stored on an access card, which can be verified in an access control system connected to the door terminal.
- Biometric data like fingerprint readers, retina scanners, three dimensional face recognition via video cameras etc. can also be used to qualify the identification information stored on the card.
- a card is omitted and access is controlled only by retina scanning and/or finger print readings for example.
- Traditional Access control systems may track a person at the access points, but normally not in between access points.
- Traditional access control systems may not identify wherein a person is located inside the building before arriving at an access point using a specific access card issued to the person.
- Traditional access control systems may not be able to verify the true identity of a person before being verified via for example a video camera or by security personnel looking at passports etc.
- Patent application US 20130017812 A1 disclose a computer-implemented method and system providing remote access control of residential or office buildings.
- the disclosed method allow employing virtual doorman functions in non- doorman buildings.
- An example of a method may comprise steps of receiving a call signal from an intercom station; the call signal comprising a resident identifier which indicates a resident with whom a visitor is trying to communicate; receiving a video stream generated by at least one camera; the video stream comprising one or more images of the visitor; retrieving visitor data associated with the resident identifier; the visitor data comprising one or more visitor profiles; and providing access to the building for the visitor based upon one or more predetermined criteria.
- This prior art system may also require extensive administration to maintain associations between visitor data and resident identifiers. If the security of the access control needs to be improved, this prior art system may rely on the more traditional access controls discussed above.
- an access control system comprising an access server system in communication with a smart phone configured with an access application program configuring the smart phone to function as an access card.
- an access control system controlling access of persons entering restricted areas comprising:
- a door system configured to open or close an associated door or gate leading into the restricted area on command from an access server system
- the door system comprises at least a door display located on a side of the door
- the access server system displays a specific QR code on the door display, wherein the displayed QR code is changing whenever the door system is closing the door and is signalling the access server of the event of closing the door.
- the invention is further providing a method of accessing a restricted area in an access control system comprising steps of:
- the smart phone is configured to send the confirmation code to the door system over an established Bluetooth channel between the door system and the smart phone
- the door system opens the door or gate associated with the door system.
- FIG. 1 illustrate an example of embodiment of the present invention.
- FIG. 1 illustrate further details of the example of embodiment illustrated in Figure 1.
- FIG. 3 illustrate further details of the example of embodiment illustrated in Figure 1.
- Figure 4 illustrates further detail of the example of embodiment illustrated in Figure 1.
- Access control of restricted areas is at least a two-fold process. Firstly, it may involve verifying the identity of a person before the person is granted permission to enter the restricted area, i.e. that the person is who he says he is. Secondly, when entering a restricted area, it may be necessary to check or verify that the person entering a restricted area is the same person that was granted access to the restricted area, i.e. that the person trying to enter is not a different person pretending to be the person that was granted access to the restricted area.
- the false passport is associated with a living person. If the passport is in the name of a non-existing person, online checking of the passport at a border crossing for example would reveal the false passport quickly. Therefore, the passport needs to be in the name of an existing person, which biometric data is known by the authority issuing the passport. If biometric data is controlled by comparing pre-stored biometric data in a central server system, and/or which are stored in a passport, with corresponding biometric data acquired at a control station, the corresponding biometric data of the physical person in question will probably reveal a false passport.
- a passport used in verifying a person ' s identity by a private enterprise may be done on basis of the visible information written in the passport, and the information that can be read out from the embedded chip in the passport. Such operation should always be granted by the person in question in writing. Some jurisdiction may not allow this operation at all.
- the visual inspection may comprise assessing if the date of birth corresponds with the apparent age of the physical person carrying the passport, etc.
- a private enterprise can always ask a person to identify himself with a valid identification paper or card like a passport or a national identity card etc.
- the identity paper can in any circumstances be copied by the private enterprise, which can be handed over to the police if it later on turns out that the person was having a false identity. Further, trained personnel of an enterprise can conduct visual inspections as discussed above.
- An aspect of the present invention is to simplify the administrative aspect related to an access control system.
- An aspect of the present invention is to allow respective persons (visitor and/or employees) to create their own verified access identity by using their own smart phone.
- Access tokens like an access card can be advanced devices comprising embedded microelectronics, which for example can store biometric data.
- Such cards are issued by a competent department of an enterprise, for example. A person need to show up in person and record details of who the person is etc. A verification is normally done of the authenticity of the person.
- the access card is manufactured and made such that it will be difficult to copy a card to make a false access card.
- the aspect of the present invention of using a smart phone as an access card makes it necessary, especially if the security level of an area is very high, to authenticate the smart phone as a genuine access card. Therefore, there are three possible authentication processes involved :
- the system according to the present invention is based on a server/client model wherein the client is a smart phone installed with an access control application according to the present invention.
- the access server (computer system) according to the present invention is controlled by a person or persons authorized to handle the access server system configured to control access of a specific geographical area, and/or a residential area and/or a building.
- Figure 1 illustrate some respective system components and main communication flow between system components according to an example of embodiment of the present invention.
- a communication channel is established between the smart phone and the access control server system of the present invention.
- the access point 15 refer to a door locking/door opening mechanism or door system located at the door entrance.
- the door lock is operated electronically as known in prior art.
- the door locking system is located on both sides of the door.
- a first step of controlling access through a door is to make sure the physical presence of the person trying to pass the door system, i.e. opening the door.
- a door system at an access point 15 comprises at least a small display (not illustrated) beside the door.
- the door display is in communication with an access server system 14, and the access server system 14 is displaying 11 a QR code 10 on the door display.
- the access application program running in his smart phone in his smart phone may be configured to send 12 the QR code back to the server system 14.
- the access server system 14 is changing the QR code 10 whenever the door is closed. Therefore, the feedback of the QR code 10 is a strong indication of physical presence of the person.
- the QR code 10 can include for example comprise
- the door system may comprise a Bluetooth transceiver, which may be interfaced to a local area network connected to the access control server 14. Thereby it is possible to set up a Bluetooth communication channel between a smart phone located close to the door of the access point 15 and the access control server 14.
- Standard Bluetooth wireless radio range is normally maximum 10 meters. However, it is possible to shield a Bluetooth transceiver inside for example a door frame around the door at the access point 15. Thereby the Bluetooth range may be limited to a few meters. The point is that the Bluetooth communication can only take place when the person is standing rather close to the door. This is serving as a presence detection of the person in front of a specific door.
- QR code 10 A security aspect of the use of a QR code 10 is the optical communication between the smart phone and the door locking system.
- the optical communication over a short range, i.e. the distance between the smart phone and the display makes it difficult to spy or steal a specific QR code by a third person.
- the recognition of the QR code can be sufficient to grant access for the person.
- three dimensional face recognition can be used.
- the access app instructs the person to start the video camera and make a video of the persons face seen from different angles (3D recognition).
- the live video stream is sent 12 to the access server system 14 that returns an accept signal 13 to the smart phone.
- the smart phone issues an open door command via fort example the Bluetooth communication channel.
- the door is opened, the person passes the door, and the door closes and the access control server system 14 submits 11 a next QR code 10 to the display. It is also within the scope of the present invention to apply for example a fingerprint reader in an example of embodiment of a door system.
- the person issues a request to the responsible department, i.e. the person or persons authorized to authenticate access to the requested object (building, residential area etc.), or directly by sending a message to the access server system 14 that can be configured to interpret requests for access.
- the request is temporarily approved by transferring a link to the requesting person ' s smart phone comprising a link to an access server system 14 from which the requesting person can download the access control application, the access app, to his own smart phone.
- identification details like phone number, photo of the persons face, date of birth, social security number etc. is available to the access server system, for example via Internet, from a database of the company comprising data about employees.
- a door system according to the present invention may comprise a passport reader as found at airports.
- the requesting person may receive a PIN code to his smart phone via e-mail or SMS for example, which is necessary to enter when starting configuring the access control application.
- the access control application can automatically start a front side video camera on the phone instructing the requesting person to film himself by moving the camera around his face. Thereby, a three dimensional image of the requesting person's face is created. This image can then be stored in the access server system 14.
- the level of scrutiny of the requesting person depends on the security level required at the premises protected by the access system. Therefore, in lower security level cases the temporarily approval can happen automatically without interference from any authorized persons controlling the access to the protected building or area. Basis for an interim or temporarily approval can be provided for by a PIN code sent the requesting person as discussed above.
- a visitor can receive a link to the access control application by an employee or any other trusted person in an organization comprising a link to a server system, for example the access control server system 14, from which the visitor can download the access application program according to the present invention.
- Figure 2 illustrate a flow of steps when registering an employee provided with the access app according to the present invention.
- a human resource department will enter personal data 20 related to the employee in an employee database. Copies of identification papers like drivers licence, passports etc. 21 may also be added. Then the company assign and define authorization rules and access rules 22 for the specific employee, i.e. at which security level the employee will function. The first time the employee is registered, an e-mail with username and encrypted password will be sent to the employee enabling the employee to download the access app 23 and start configuring the access app.
- Respective authorization rules and access rules will be downloaded to respective door systems thereby being configured to allow passage of the employee through respective doors according to the defined access rules of the employee. For example, which area of a building the employee has access, or which areas of the building the employee is denied access.
- Figure 3 disclose flow of steps for a visitor.
- a visitor is usually in contact with an employee that will accept a visit from the visitor.
- the flow represent a simple process of gaining access to the company or organization the visitor plans to visit.
- the reason behind this is the ability of the combined functionality of the access app and the access server according to the present invention to install access rules residing in door systems.
- Some personal data 30 of the visitor is necessary to enter together with for example date of the visit and the hours of the day the planned visit will occur. Thereby, the access application program of the visitor is valid only during a narrow time window on a specific day.
- the visitor receives 31 for example an SMS with a link to the access application access program and authorization code, for example a PIN code, which enables the visitor to download the access application program to his smart phone.
- authorization code for example a PIN code
- a picture or video of the visitor (taken by the visitor himself) 32 can be stored in the access control server system 14 and be used in a three dimensional face recognition process as discussed above when the visitor enters a door.
- Figure 4 illustrate a flow diagram representing process steps implemented in the access app, and how the access app communicate with an access server according to the present invention thereby providing functionality as discussed above of the door system and respective access rules.
- the access "card” is a smart phone
- tracking of movement of the smart phone inside buildings is possible, for example monitoring GPS positions sent from the smart phone, or by using Internet access points of local area networks to identify positions.
- the access server 15 may be configured to plot movements on a map depicting the interior of the building.
- an accelerometer of a smart phone may track movement patterns of a person. Such movements may be individual if a person has suffered some accident or illness that has caused permanent damage to a limb etc., and can be detected in a movement pattern recognition process, wherein a measured movement pattern identified by accelerometer values is compared with previously recorded movement patterns of the same person. This can be part of a further step of verifying the identity of a person.
- the accelerometer measurements may also reveal if a person is running, which may be portrayed has a suspicious act by the access control server system 14.
- the access control server system 14 may be configured to identify such a situation and generating a warning to security officers on the premises of the access system according to the present invention. It is also within the scope of the present invention to use voice recognition processes when authenticating a person.
- the door system according to the present invention is equipped with a battery backup providing emergency power.
- a copy of the access data, i.e. access rules etc. is stored locally in a computer system located at the door system. Thereby a person can use the access app and be allowed to pass a door.
- the access server system 14 may be configured to open up all doors and gates in the building. It is also possible to have a smoke and fire detector system nearby respective doors. When a fire, or a possible fire is detected nearby the door, the door system opens up the doors.
- Some of the tools used in respective examples of embodiments of the present invention are commercial available.
- face recognition programs that may be used is for example Google MLKIT and Azure Face API.
- the first step discussed above of verifying a person ' s identity is performed after a person has passed an access controlled door and closed the door again. If the identity should be revealed as false, the access control system according to the present invention can automatically call the police and will not open the door again before police is present.
- a first step according to the present invention is to give a person access to the access application converting the persons smart phone into an access card or access token.
- Restricted areas having a lower security requirement may utilize the example of embodiment according to the present invention as discussed with reference to Figure 1. If a higher security level is required, the example of embodiment discussed with reference to Figure 1 will always be a starting point, and additional control mechanisms is built as additional features of the example disclosed in Figure 1.
- a first QR code 10 displayed on the door panel may comprise instructions for establishing a short range Bluetooth communication channel between the door system comprising a Bluetooth transceiver and the access control server system 14 over a local area network.
- the Bluetooth communication channel is established when the first QR code is interpreted, via a photo of the QR code, by the access application program running in the smart phone.
- the access server system 14 may be configured to read out the telephone number from the phone over the Bluetooth communication channel. The phone number can then be compared with respective phone numbers used when access applications has been downloaded into respective smart phones. If the phone number of the smart phone is among the phones being configured with the access applications, the access server system 14 knows that this phone belongs to a person that has been in contact and has been granted to receive the access application and configures the smart phone as an access card or access token.
- the downloaded access application may be tailored with some specific information the person downloading the application is not aware of.
- a specific secret user identity which can be an encrypted code, used within the access control system of the present invention for each person requesting a download of the access application, which can be embedded in the downloaded code.
- a specific user identity code may only be generated after the person in question has provided strong identification of who he is, for example providing details of a passport.
- the telephone number is something the person has (ref. 2 above).
- the secret user identification is something the person has indirectly when downloading the access application from the application server system 15.
- the telephone number is transmitted from the phone via the Bluetooth connection and fulfils requirement 2).
- Requirement 1 can be fulfilled with a one-time password qualified by a PIN code known by the user.
- the one-time code should be related to the unique secret user identity thereby making it difficult to utilize a stolen PIN code of another person that has been granted access.
- the access control server system 14 When the first QR code 10 is photographed by the user with the user ' s smart phone camera, the access control server system 14 knows the identity of the person by searching the phone number among the phone numbers used when downloading the access application to respective phones. Then the secret user identity is also revealed to the access server system 14. The access server system may then be configured to generate a second QR code 10 ' being an instruction to the access application program to generate a one-time password. The access application in the smart phone is configured to generate a one-time password when the user has photographed the second QR code with the instruction of generating the one-time password, and when the person enters for example a one-time PIN code.
- the one- time PIN code can be issued and sent to the smart phone in an SMS message, or via the Bluetooth connection, at the same time the second QR message is displayed.
- the one-time password is generated based on the secret user identity embedded into the access application.
- the one-time password is sent to the access control server 14 via the established Bluetooth communication channel. In this manner the requirement 1) is fulfilled.
- the actual encryption and decryption algorithm can be one of several prior art encryption/decryption schemes.
- the one-time password is then transmitted over the Bluetooth communication channel back to the access server system 14, which is configured to verify the one-time password. If the one-time password is correct the access control server system 14 issues a command opening the door.
- the optical aspect of photographing the first and second QR codes on the display on the side of the door prevents any form of sniffing or spying or copying sensitive information that could be used to fake an entry into a restricted area. Further, a designed short range of the Bluetooth communication range ensures that the person is close to the door.
