Method and system for reducing the impact of an undesired event using event-based distribution of certificates
First Claim
1. A method for reducing overflow caused by an appliance using a liquid, the method comprising:
- detecting if the appliance has undesirably emitted part of the liquid,generating an alarm event if the appliance has undesirably emitted part of the liquid,sending a certificate, via a cellular network, to a predetermined first party, wherein said certificate, upon said predetermined first party sending a lock/unlock command comprising said certificate, authorizes said first party to enter the location in which said appliance is located, andsending a digital authentication key for signing of said lock/unlock command comprising said certificate to said first party, wherein the certificate is associated with the digital authentication key, the certificate certifies the authenticity of the digital authentication key, and the digital authentication key comprises information identifying the first party,wherein the predetermined first party is a first server and wherein the method further comprises;
the first server selecting a second party from a predetermined list, andthe first server forwarding the certificate to the second party;
wherein the selecting from the predetermined list is based on which party on the list is geographically closest to the location in which the appliance is located using Global Positioning System technique.

Abstract
The present invention relates to a method and a system for reducing overflow caused by an appliance (100) using a liquid. The system comprises: a detector (200) arranged to detect if the appliance (100) has undesirably emitted part of the liquid, an internal server (300) being arranged to generate an alarm event in case the appliance (100) has undesirably emitted part of the liquid, and an external server. The external server is arranged to send, via a cellular network, a certificate to a predetermined first party in case an alarm event is generated. The certificate authorizes the first party to enter the location in which the appliance is located.

13. A method for reducing overflow caused by an appliance using a liquid, the method comprising:
-
detecting if the appliance has undesirably emitted part of the liquid, generating an alarm event if the appliance has undesirably emitted part of the liquid, sending a certificate, via a cellular network, to a predetermined first party, wherein said certificate, upon said predetermined first party sending a lock/unlock command comprising said certificate, authorizes said first party to enter the location in which said appliance is located, and sending a digital authentication key for signing of said lock/unlock command comprising said certificate to said first party, wherein the certificate is associated with the digital authentication key, the certificate certifies the authenticity of the digital authentication key, and the digital authentication key comprises information identifying the first party, wherein the step of detecting if the appliance has undesirably emitted part of the liquid is; detecting how much liquid flows into the appliance per unit of time and sending the detected information, via a short range wireless protocol, to an internal server, computing the amount of liquid that has flown into the appliance at a certain point of time, and wherein the step of generating an alarm event if the appliance has undesirably emitted part of the liquid is generating an alarm event in case the amount of liquid that has flown into the appliance at a certain point of time is larger than a predetermined value. - View Dependent Claims (14)
