Resource sharing using device location tracking and blockchains

Abstract:

An access control system that includes Internet of Things sensors and a controller within a controlled area. The controller is configured to detect a guest device for a guest, to identify a sponsor associated with the guest, and to identify a sponsor block chain account for the sponsor. The controller is configured to publish an access control contract to the block chain that includes executable instructions for publishing a transaction in the block chain transferring credits from the sponsor block chain account to a vendor block chain account and conditions linked with the instructions. The controller is configured to receive an access request, to determine whether the conditions have been satisfied, and to send a trigger message that triggers the access control contract to execute the instructions in response to determining the conditions have been satisfied.
