Abstract
A method and device for delivering one or more keys to an offline mobile communication device are provided. The method includes receiving the one or more keys from a backend issuance system, preparing the one or more keys for delivery to the offline mobile communication device via a short-to-medium communication channel, and transmitting the one or more keys to the offline mobile communication device via the short-to-medium range communication channel.
Claims19
A method for delivering an access control key to a mobile device, comprising:
- determining that a mobile device is not in communication via a primary network connection with a key issuance backend, the mobile device being a portable device associated with a user authorized to receive the access control key, and the mobile device comprising a network interface that is at least one of:
- limited in functionality, disabled, or otherwise prevented from directly transmitting requests to the key issuance backend;
- establishing, based on the determining, a proximity-based communication channel between the mobile device and an update reader as an alternative update channel to the primary network connection;
- receiving an update request at the update reader from the mobile device, wherein the update request is communicated via the proximity-based communication channel;
- providing the update request to the key issuance backend on behalf of the mobile device, wherein the update request is provided to the key issuance backend by the update reader having a network interface that enables communications with the key issuance backend;
- receiving, at the update reader, the access control key from the key issuance backend in response to the update request, wherein the access control key is configured to be provided to an access control reader, different than the update reader, and authorizing access by the user to a physical asset protected by the access control reader;
- and
- transmitting the access control key from the update reader to the mobile device via the proximity-based communication channel such that the access control key is stored in a memory of the mobile device for later presentation by the mobile device to the access control reader to obtain the access.
5 more elements
An update reader device, comprising:
- a network interface that facilitates communications with a key issuance backend via a communication network;
- a device interface that facilitates establishment of a proximity-based communication channel with a mobile device in response to the mobile device being brought within a predetermined distance of the update reader device and in response to a determination that the mobile device is not in communication via a primary network connection with the key issuance backend, wherein the proximity-based communication channel is established as an alternative update channel to the primary network connection, the mobile device being a portable device associated with a user authorized to receive or carry a key issued by the key issuance backend, and the mobile device comprising a network interface that is at least one of:
- limited in functionality, disabled, or otherwise prevented from directly transmitting requests to the key issuance backend;
- a processor;
- and
- memory including instructions that, when executed by the processor, enable the update reader device to transmit an update request to the key issuance backend on behalf of the mobile device and then provide the key or an update corresponding to the key to the mobile device via the proximity-based communication channel, wherein the key is configured for storage by the mobile device and then presentation by the mobile device to an access control reader, different than the update reader device, authorizing access by the user to a physical asset protected by the access control reader.
3 more elements
A physical access control system, comprising:
- one or more access control readers that protect one or more respective physical assets;
- and
- an update reader device, different than the one or more access control readers, the update reader device comprising:
- a network interface that facilitates communications with a key issuance backend via a communication network;
- a device interface that facilitates establishment of a proximity-based communication channel with a mobile device in response to the mobile device being brought within a predetermined distance of the update reader and in response to a determination that the mobile device is not in communication via a primary network connection with the key issuance backend, wherein the proximity-based communication channel is established as an alternative update channel to the primary network connection, the mobile device being a portable device associated with a user authorized to receive or carry a key issued by the key issuance backend, and the mobile device comprising a network interface that is at least one of:
- limited in functionality, disabled, or otherwise prevented from directly transmitting requests to the key issuance backend;
- a processor;
- and
- memory including instructions that, when executed by the processor, enable the update reader device to transmit an update request to the key issuance backend on behalf of the mobile device and then provide a key or an update corresponding to the key to the mobile device via the proximity-based communication channel, wherein the key is configured for storage by the mobile device and then later presentation by the mobile device to at least one of the one or more access control readers, authorizing access by the user to one or more physical assets protected by the at least one of the one or more access control readers.
