Abstract

A method for initiating a security procedure within a building whereby a virtual key is generated by a certain event and transmitted to a selected person. If the selected person identifies himself by means of the virtual key, a security procedure, for example making an elevator available, is initiated within the building.

Claims

1. A method of initiating a security procedure within a building having a security system for controlling the security procedure comprising the steps of:

a. generating a virtual key in response to an occurrence of a certain event related to a security procedure in a building;

b. transmitting the virtual key to a selected person; and

c. initiating the security procedure within the building when the selected person identifies himself with the virtual key to a security system of the building.

2. The method according to claim 1 wherein a certain code is assigned to the virtual key by a selected encryption method.

3. The method according to claim 1 including adding a signature to the virtual key with which the selected person can identify himself to third parties as an authorized person.

4. The method according to claim 1 wherein a type of the security procedure depends upon a type of certain event.

5. The method according to claim 1 wherein the security procedure controls an elevator in the building.

6. The method according to one of claim 1 wherein the selected person to whom the virtual key is transmitted depends upon a type of the certain event.

7. The method according to claim 1 including checking whether a previously generated virtual key exists for the selected person and, if so, whether the previously generated virtual key is being used with modification.

8. The method according to claim 1 including checking whether a previously generated virtual key exists and fulfils security requirements of the security system and, if necessary, generating a new or augmented virtual key.

9. The method according to claim 1 including checking what means are available to the selected person to identify himself and selecting a suitable one of the available means.

10. The method according to claim 1 wherein the selected person identifies himself when receiving the virtual key.
