Description

AN ACCESS SYSTEM AND A METHOD AND AN APPARATUS FOR ACCESS CONTROL
BACKGROUND
In various user access or entry points, a turnstile, a security barrier or an access gate may use a curtain of light type of sensors that detect a person. User identification for access requires interaction at the entry point. A user is granted an access at the entry point only when the user has been identified. All this takes time and these actions have to be performed separately for each user at the entry point. Further, user behaviors at the entry point differ from each other, and some users act quicker than others. A significant number of users fail to operate in a timely manner at the entry point and this slows down the throughput of the entry point.
Thus, it would be beneficial to have a solution that would alleviate at least one of these drawbacks.

DETAILED DESCRIPTION
FIG. 1 illustrates a flow chart of a method for access control according to an example embodiment. The illustrated method may be applied, for example, in any environment where a major part of users can be identified, for example, in an office building environment .
At 100, identification data is received from at least one user identification means. The identification data may refer to any data provided by the user identification means, for example, to identification data obtained from a user by the user identification means, to identification data obtained about the user by the user identification means etc. The user identification means may refer, for example, to at least one of biometric identification means, optical identification means, radio frequency based identification means, and magnetic identification means or to any other type of user identification. At 102, it is determined, based on the identification data and prestored data on users, whether the identification data relates to an identified user with an access via a user entry point 202, an identified user without an access via the user entry point 202, or an unidentified user. The prestored data may be stored, for example, in a local database, and the identification data may be compared to the prestored data in order to find a possible match from the prestored data. In another example embodiment, the prestored data may be stored by a cloud service accessible via a network connection. The prestored data may further comprise access data relating to the identified users having the access via the user entry point 202 in order to determine the identified users with the access via the user entry point 202 and the identified users without the access via the user entry point 202.
At 104, a user entry point for the identified user with the access via the user entry point 202, the user entry point being by default at a state allowing an unrestricted access via the user entry point 202, is maintained at the state allowing the unrestricted access via the user entry point 202, when the identification data relates to the identified user with the access via the user entry point 202.
At 106, the user access restriction means are controlled to restrict access via the user entry point 202, when the identification data relates to the identified user without the access via the user entry point 202 or the unidentified user. The user access restriction means may provide at least one of a visual and audible alert for the unidentified user, when the identification data relates to the unidentified user, and/or a physical access restriction at the user entry point, when the identification data relates to the unidentified user. Alternatively, the user access restriction means may provide at least one of a visual and audible alert for the identified user without the access via the user entry point 202, when the identification data relates to the identified user without the access via the user entry point 202, and/or a physical access restriction at the user entry point 202, when the identification data relates to the identified user without the access via the user entry point 202.
FIG. 2 illustrates an access system 212 according to an example embodiment. The access system 212 comprises a controller 200, a user entry point 202, user access restriction means 204 at the user entry point and at least one user identification means 206.
The user entry point 202 may refer to any point of access through which a user has to travel and in which user access may be restricted depending on whether the user is identified or not and whether the identified user has access via the user entry point 202 or not. The user access restriction means 204 may refer to any means for providing a visual and/or audible alert for an identified user without an access via the user entry point 202 or an unidentified user. Additionally or alternatively, the user access restriction means 204 may provide a physical access restriction at the user entry point 202, when the identification data relates to the identified user without the access via the user entry point 202 or the unidentified user. For example, if the user entry point 202 involves a turnstile, the turnstile may be closed when the identification data relates to the identified user without the access via the user entry point 202 or the unidentified user. In an example embodiment, the user access restriction means 204 may comprise at least one of a door, a turnstile, an automatic building door, a door frame, an escalator entrance, a security barrier, an access gate, an electronic access gate, and alerting means. Further, in an example embodiment, the at least one user identification means 206 may comprise at least one of biometric identification means, optical identification means (for example, at least one camera) , radio frequency based identification means, and magnetic identification means or any other type of user identification means.
In existing solutions, when an entry via a user entry point presumes successful user identification, the user entry point is in a closed state (for example, user access is physically prevented using e.g. a gate) . Only after a successful user identification, the gate is opened and the user is able to go through the user entry point. This means that the user identification procedure is performed only at the gate.
In the example embodiment illustrated in FIG. 2, the user entry point 202 is by default at a state allowing an unrestricted access via the user entry point 202. In other words, the user entry point 202 is maintained at the state allowing the unrestricted access via the user entry point 202, when the identification data relates to the identified user with the access via the user entry point 202.
The user identification means 206 enable user identification at a first distance 210 away from the user entry point 202. In one embodiment, the user identification means 206 may be arranged at the user entry point 202 or close to the user entry point 202 In another embodiment, the user identification means 206 may be arranged at a second distance away from the user entry point 202, for example, 1 - 5 meters or 1 - 10 meters before the user entry point 202. The first distance may be, for example, 0- -10 meters from the user entry point 202, and preferably 1 - 2 meters, 1 - 3 meters or 1 - 5 meters. The user identification means 206 may refer to a single identification means or to a combination of several separate identification means. In one example embodiment, a user may be identified using a radio frequency based identification, for example, Bluetooth, radio frequency identification (RFID) or near field communication (NFC) . In another example embodiment, the user may be identified using both the radio frequency based identification and facial recognition provided by optical identification means, for example, a digital camera. It is evident that these identification types are only examples, and other identification solutions and technologies may be used alternatively or additionally . When the user 208 reaches the user identification means 206, the user identification means 206 obtain user identification data about the user. The user identification data may be obtained from the user 208, for example, via a radio frequency based identification solution. Alternatively or additionally, the user identification data may be obtained about the user 208, for example, via a biometric or optical identification solution . The user identification means 206 are connected to the controller 200, and the controller 200 is configured to receive the user identification data from the user identification means 206. After receiving the user identification data, the controller 200 is configured to determine, based on the identification data and prestored data on users, whether the identification data relates to an identified user with an access via the user entry point 202, an identified user without an access via the user entry point 202, or an unidentified user. The prestored data may be stored in a memory or database connected to the controller 200, or in a cloud service accessible via a network connection. As an example, if the user entry point 202 is arranged in an office building, identification data relating to people regularly working in the building may have been prestored in the memory or database. The prestored data may further comprise access data relating to the identified users having the access via the user entry point 202 in order to determine the identified users with the access via the user entry point 202 and the identified users without the access via the user entry point 202. When the identification data relates to the identified user with the access via the user entry point 202, the controller 200 is configured to maintain the user entry point 202 for the identified user with the access via the user entry point 202 at the state allowing the unrestricted access via the user entry point 202. Further, when the identification data relates to the identified user without the access via the user entry point 202 or the unidentified user, the controller 200 is configured to control the user access restriction means 204 to restrict access via the user entry point 202.
If the controller 200 determines that the user identification data relates to an unidentified user, the controller 200 may be configured to control the user access restriction means 204 to provide at least one of a visual and audible alert for the unidentified user. Alternatively, if the controller 200 determines that the user identification data relates to an identified user without an access via the user entry point 202, the controller 200 may be configured to control the user access restriction means 204 to provide at least one of a visual and audible alert for the identified user without the access via the user entry point 202. As an example, if the user entry point 202 comprises a gate, the user access restriction means 204 may refer, for example, to a blinking red light (s), a light projection on a floor etc. In another example embodiment, additionally or alternatively, the user access restriction means 204 may provide a physical access restriction at the user entry point 202, when the identification data relates to the identified user without the access via the user entry point 202 or the unidentified user. The physical access restriction may refer, for example, to a closing gate, a closing door, a security barrier rising from a floor etc.
In an example embodiment, the user access restriction means 204 may be integrated with the user entry point 202. For example, if the user access point 202 comprises a gate, the gate may be kept open by default, and only when the controller 200 acknowledges an identified user without an access via the user entry point 202 or an unidentified user, the gate may be closed for the identified user without the access via the user entry point 202 or the unidentified user, respectively.
The solution illustrated in FIG. 2 enables a solution in which the user access restrictions means 204 may restrict user access fast and well ahead if an unknown person is detected. For example, this may mean that only 5% of all users, typically visitors, courier service, etc. encounter a restricted access. The user entry point may ask for a visitor card or other identification to enable access or simply command a visitor to register in first.
The access system 212 illustrated in FIG. 2 may be integrated with a people transport system, for example, an escalator, an elevator etc. In other words, the user entry point 202 would be located in immediate vicinity of a starting point of the escalator.
FIG. 2 illustrates that the user identification means 206 may be arranged at a predetermined distance 210 away from the user entry point 202. This in practice may mean that a user may have already been identified (or classified as an unidentified user) before the user reaches the user entry point 202. In an example embodiment, the access system 212 may comprise a secondary user identification means at a secondary point to identify a specific unidentified user that has arrived at the user entry point 202 or is close to the user entry point 202. The secondary user identification means may be arranged at the user entry point 202 or close to the user entry point. This enables a solution in which the access system is aware of the location of a specific unidentified user and can restrict access for this user. The user identification at the secondary point may be performed, for example, using facial recognition, biometric identification means or any other appropriate technique.
In an example embodiment, the access system 212 may be used in connection with an elevator system. In this example, the user access point 202 may comprise a door or doors of an elevator. When the access system 212 identifies that a user is an identified user with the access via the user entry point 202, the user is allowed to enter an elevator car via the elevator door when the user has made an elevator call.
FIG. 3 illustrates a block diagram of an apparatus 200 according to an example embodiment. The apparatus 200 comprises one or more processors 300, and one or more memories 302 that comprise computer program code. The apparatus 200 may also include an input/output module (not shown in FIG. 3), and/or a communication interface (not shown in FIG. 3) .

For example, the processor 300 may be embodied as one or more of various processing devices, such as a coprocessor, a microprocessor, a controller, a digital signal processor (DSP) , a processing circuitry with or without an accompanying DSP, or various other processing devices including integrated circuits such as, for example, an application specific integrated circuit (ASIC) , a field programmable gate array (FPGA) , a microcontroller unit (MCU) , a hardware accelerator, a special-purpose computer chip, or the like. In an example embodiment, the processor 300 may be configured to execute hard-coded functionality. In an example embodiment, the processor 300 is embodied as an executor of software instructions, wherein the instructions may specifically configure the processor 300 to perform the algorithms and/or operations described herein when the instructions are executed.
The memory 302 may be embodied as one or more volatile memory devices, one or more non-volatile memory devices, and/or a combination of one or more volatile memory devices and non-volatile memory devices. For example, the memory 508 may be embodied as semiconductor memories (such as mask ROM, PROM (programmable ROM) , EPROM (erasable PROM) , flash ROM, RAM (random access memory) , etc . ) .
The apparatus 200 may be a control entity configured to implement only the earlier discussed features in the example embodiments, or it may be part of a larger control entity.
In an embodiment, the at least one memory 302 may store program instructions that, when executed by the at least one processor 300, cause the apparatus 200 to perform at least: receiving identification data from at least one user identification means 206; determining, based on the identification data and prestored data on users, whether the identification data relates to an identified user with an access via a user entry point 202, an identified user without an access via the user entry point 202, or an unidentified user; maintaining a user entry point 202 for the identified user with the access via the user entry point 202, the user entry point 202 being by default at a state allowing an unrestricted access via the user entry point 202, at the state allowing the unrestricted access via the user entry point 202, when the identification data relates to the identified user with the access via the user entry point 202; and controlling the user access restriction means 204 to restrict access via the user entry point 202, when the identification data relates to the identified user without the access via the user entry point 202 or the unidentified user.

One or more of the above illustrated examples and example embodiments illustrated, for example, in relation to FIGS. 1 - 3 may provide one or more of the following advantages and/or effects.
The illustrated solution may save time that is used to open and close door blades at the user entry point. A curtain of light based gate and passage solutions allows only one person to enter at time. In the illustrated solution, there is no need to wait for a turn to enter. The illustrated solution may also enable a dramatically longer lifetime and service interval for the user access restriction means, for example, door blades. Further, doors can be kept always open for all known people that have an access via the user entry point, for example, in an office building. This saves time, and may encourage people to move faster. Further, the walking speed of users does not slow down at the user entry point. Further, the illustrated solution may allow well working and intuitive use of an electronic gate that has no blades. The gate may blink red, make a light projection on floor, provide sound or another alert well before user is entering the gate.
