EP1158466A1 - Method for triggering a process within a building - Google Patents

Abstract

The method involves generating a virtual key as a result of a defined event, transmitting the generated key to a person and triggering the process within the building when the authorized person is identified by the key. The key is allocated a defined code using an encoding method and a signature accompanies the code to enable the receiver of the key to identify himself to a third party as an authorized person.

Description

The invention relates to a method for triggering a Operation within a building.

Modern buildings, especially more complex buildings, exhibit meanwhile a comprehensive infrastructure on how Example doors in the entrance area and possibly on the respective floors with electronic access control, Turnstiles with electronic access control and Elevator systems, also with access monitoring are equipped.

Suddenly urgently needs a person in this building medical attention, so a number of operations be carried out without causing breakdowns may. First, the person who needs help needs one give further person to understand that they help and in how much help she needs. This additional person must then inform the emergency doctor and make sure that the Building staff knows about the emergency doctor visit Emergency doctor receives through the safety barriers in the building smuggles the emergency doctor to the appropriate floor and in leads the corresponding room in the building, where the needy person. It has to be Building staff fully and correctly informed as well be instructed. Accidental misinformation can have fatal consequences. In addition, the emergency doctor must be as soon as possible can reach the person in need. This demands a high administrative effort and the staff must be fully trained.

Another case can be that of one in the building a working person or a resident of the building Order is placed. That person or the resident however, for whatever reason the ordered one can Do not accept goods or services yourself. The Person or the resident must therefore actively take care of it carry that the goods or service ordered also in Can be received. This can usually be done by doing so that the person or the resident take another Instruct person to do this task for you takes over. Is such a person unavailable or coming there is a misunderstanding, so the goods ordered or Service not receivable, which in turn is corresponding Can have consequences.

In the event that a building cleaning service to determine Times to clean and close certain parts of the building has to maintain, you have to clean the cleaning staff accordingly Provide access rights. This usually happens in that the cleaning staff one or more mechanical keys are given for certain Lock doors. It is not guaranteed that the Person who holds this key is also required to Cleaning staff heard. There is still the problem that if the key is lost, significant damage can arise. Misuse cannot be ruled out here.

In the event that a building resident has multiple visitors expected, he must each individual visitor who is on Reception reports, access to the building and if necessary, a new directions every time where he can be found in the building. This can be done under Circumstances can be quite tedious.

Will be in the building or in an apartment of the building one-off or infrequent service performed, this is just an access authorization for the service personnel feasible with high administrative effort. Either a person must or must accompany the service personnel a mechanical key for the service personnel Be made available to some Advance of trust required and the risk of abuse elevated.

An object of the invention is therefore to provide a method for Trigger an operation within a building, in a safe way, automatically and certain components of an authorized person without errors the infrastructure of the building become.

The task is accomplished through a method of triggering a Operation within a building with the in claim 1 specified features solved.

Advantageous developments of the invention result from the features specified in the dependent claims.

In the method according to the invention for triggering a Operation within a building is determined by a particular one Event generated a virtual key. The virtual one The key is then sent to a person. If the authorized person by the key identified, the process is triggered in the building.

The key is advantageously by means of a A specific code is assigned to the encryption method.

It is also advantageous for the key to have a signature enclosed with which the recipient of the key Show third parties as a person authorized to use can.

It is also advantageous that the type of operation is different from the Type of event is made dependent.

The process advantageously controls one in one Building elevator.

Another advantageous development of the invention is that depends on the type of event to whom the key is transmitted.

It can also be checked whether the person who the Key is transmitted, a key already exists and is used modified if necessary.

Another advantage of the invention is that it is checked which means of the person to be authorized for Be available to identify yourself and one of them suitable is selected.

In a further embodiment of the invention, the If a key already exists, checks whether this meets the security requirements and if necessary, a new or an expanded key generated.

The person advantageously identifies himself with the Receiving the key.

The invention will be further elucidated in the following on the basis of a figure explained.

The figure shows a flow chart for the inventive Procedure for triggering an event within a Building.

Triggering element is as shown in the figure certain event. The event can be as above already mentioned, an emergency call, an order, a Order, for example for a cleaning service, a Invitation or a recurring event, for example condition monitoring or a service his.

Which type of event depends on which Requirements placed on a key to be generated become. For example, if there is a fire in the building, this is the key security requirement less high and the availability requirements of the The key higher. Is the triggering event however, an order to clean the building for one Cleaning service, so are the security requirements for to set the key to be issued significantly higher. The means that the risk of misuse of the key must be this case be kept as low as possible where on the other hand, in the event of a fire, the entrance to the building for everyone Circumstances must be guaranteed. From this result each different requirements depending on the type of event the key to be issued.

A code is supposed to be under key or virtual key be understood.

The event also determines which person should be authorized. For example, is the trigger If an emergency call occurs, the Call an emergency doctor, whereas if the triggering one Event a personal invitation from a building resident is to invite the guest (s).

Whether first the requirements for the key and then the Person / persons who should be authorized depends on the boundary conditions of the system.

Then it must be determined whether from the to authorizing person means are available, which as Keys can serve. Here come as a means for example means of communication such as telephone, Mobile devices, pagers or PC in question.

For example, the key is a secret word, one PIN, phrase, symbol or picture in question.

After the key requirements are set the person to be authorized has been determined and it has been determined whether the Person means are available that serve as keys can be checked whether the quality of a existing key meets the requirements. Is this not the case, a new key is generated or but the existing key complements that to the extent that the key requirements are met.

After a suitable key has been generated, it becomes transmitted to the authorized person. The kind of Transmission depends on the means used by the entitled party Person are available. Has the authorized person via a mobile phone, the transmission can be made via an air interface. Must be the key, however be transmitted to a fax machine, so the transmission usually done by wire. The kind of Transmission of the key depends on the technical Boundary conditions.

If necessary, you can already receive the key the authorized person is identified. This can, for example, by biometric features such as the Voice of the recipient or his fingerprint. After the key is received and if necessary the authorized user has identified himself the key on the by the authorized person Available means of communication saved. This however, is not mandatory. Rather, it can the authorized person uses the key himself notice.

As soon as the person authorized to use the corresponding When the building arrives, the key is used. Depending on The key is used, that is, the application of the Key by entering the secret number, the Secret word or the like on a keyboard that Entry of the key in spoken form by a Microphone on the building or the biometric features of the authorized person by a corresponding on Building arranged biometric sensor.

After entering the key, the Key for validity. If the key is invalid recognized, for example, if the key is only for a certain period of time is applicable due to a late Application, so there is a rejection. The person receives no access to the building, the process will not triggered.

However, if the key is recognized as valid, it is done triggering the process, for example the doors of the building opened, the elevator provided and the Elevator doors open, possibly existing ones Security barriers are unlocked. Another Operation can be the delivery of a message to the Be the sender of the key. In addition, the user of the Key route information will be communicated as to the person who sent the key. Also a greeting of the authorized user or more information for the authorized user Person has been deposited can now be played back become. The triggered process can also be an automatic Include the elevator drive to the destination floor. Finally the process can also be a receipt for the delivery of the goods or be a service.

The invention provides an electronic key for Granting access to certain areas based on external events, for example an order by Mail, a request for help, a detection of fire and so on, automatically generated and delivered. This means an automatic implication of triggering Event on the need for access and the related necessary precautions (provision and dispatch of the Key). For example, the Request of an emergency doctor using an emergency transmitter Delivery of a code to the doctor. The doctor points out to the access control system to be able to reach the patient unhindered.

The electronic key can be in the form, for example a binary represented number or sequence of numbers his. The relevant people in the generation of the Key, in the distribution and application of the The key is the person who placed the order (for example, the to visiting person), the visitor and one Administrative office. There are different shapes and Methods of identification and authentication possible, such as through "Public Key Cryptography" to provide. For this, please refer to the Publication of R.L. Rivest, A. Shamir, L. Adleman "A Method for Obtaining Digital Signatures and Public-key Cryptosystems ", 1977. In it a Encoding method described in which a Encryption key is publicly accessible without that the decryption key is publicly available is made. The procedure is also known as the RSA procedure known.

With a simple execution of the key, the Key also by a PIN code, an identifier, a Phone number or a secret word. A higher level of protection against abuse can be achieved by a public key is used for authentication and corresponding encryption methods for Communication. In a first Public authentication based phase Key distributed. Should a user have access or other rights are granted, he receives his rights, represented in numerical form and by means of public Keys delivered securely. When applying rights the decryption takes place, which ensures that the proclaimed rights, such as access to were assigned to a legitimate position. In addition, a Signature procedure can be attached, which one appropriate evidence to third parties.

The key can have different information. So it is possible that part of the key is one Signature of the recipient or the administrative agency. On Another part of the key can be the triggering event describe yourself. It is also possible to get the key Add information, for example the Access rights include, who, where and when Should have access. It can also be noted in the key what kind of right should be. After all, it is possible, only one reference or one in the key Store pointer (pointer) that is a reference to the Storage address represents the administrative office has filed the additional information.

Depending on the application, the key can be attached to one or saved several or all places his. The key becomes complete in several places stored, this means high redundancy and thus a high level of access security, but also increased Risk of abuse. Saving the key in Complete form in several places, for example be helpful in the event of a fire in the building.

The information stored in the key can be sent to the in-house receiver, for example via a Infrared interface (IrDA) or via a Bluetooth radio interface a mobile phone become.

IrDA (Infrared Data Association) provides one Infrared communication standard. It can be wireless Connections with a range between 0 and 1 meter and a data transfer rate between 9600 and 16 Mbaud be created.

Bluetooth is for short-range voice and data traffic provided with radio frequencies at 2.4 GHz in the ISM band. The Range is between 10 cm and 10 m, but can by amplification of the transmission power extended to 100 m become.

The key can be generated and distributed by different places, such as an alarm trigger, the building management agency or a third party respectively. The key is generated automatically on an indication such as that caused by an alarm given is.

Upon receipt of the key, further information and Instructions are sent, such as a Route sketch, a restriction of visiting times or Operating instructions.

For example, when using the key Notification or authentication of the user Communication link between the key sender and the key holder.

It is also possible to send the key to inform if the key expires after a certain Period was not used. It is also possible that the rights granted to authorized user at the Modify application of the key so that the authorized user no longer or only is restricted to use. In addition, the Rights of all keys are modified. Then this can be of importance when a variety of keys was distributed, but now only a part of it may be used.

The sender of the key or the administrative agent can in the event of key malfunction and / or Tampering attempts will be notified.

The key can be in a parent program be embedded so that for example a Operating program together with the key to a mobile Telephone with WAP browser is transmitted. The phone can then used as a user interface, among other things to apply the key.

It is also possible to have one for each application of the key Charge which depends on the type of key and the triggered action / the process can be dependent. The Billing can be charged to the key owner, i.e. the authorized user, the sender of the key or a third place.

There is also the possibility of a special Unlock operating mode with the key, if the key is applied. This could be particularly the case in Fire in the fire department may be of importance to you Control elevator.

If a key is used, this can be visual and / or be displayed acoustically.

If a key is not used, it can certain actions, such as reporting to the recipient of the key to the memory.

If the key is used, more can also be used Information to the lock, i.e. the electronic one Recipient are transmitted. The type of information can be determined by the key itself and / or be requested by the castle. The information can about visitor details such as personnel number, preferred Include room temperature or communication skills.
