Multi-party physical access controls

A computer program product comprising one or more computer-readable storage medium collectively having a set of instructions stored therein which, when executed by a processor, causes the processor to ensure physical access control of a lockbox by:

• monitoring physical access of a lockbox under controlled access according to a contract governing control of the lockbox;
• generating an authentication of a user by determining a first biometric reading stored for reference matches a second biometric reading submitted for the authentication, the first biometric reading associated with a user having authority to gain physical access to the lockbox according to the contract;
• recording an identity of the authenticated user to a ledger accessible over a peer-to-peer network of parties to the contract, the ledger supporting the contract by linking access activity of the parties using cryptography, the authenticated user being the user for whom the authentication was generated;
• identifying a request for physical access to the lockbox submitted by the authenticated user;
• submitting the request to an administrator for acceptance, the administrator being an authorized party of the contract;
• responsive to receiving an acceptance from the administrator, providing to the authenticated user a credential permitting access to the lockbox;
• responsive to use of the credential and opening of the lockbox, recording to the ledger the request associated with the authenticated user and an access event initiated by the authenticated user;
• responsive to the lockbox being closed at a time after the access event is recorded, recording a closing event on the ledger;
• and
• responsive to the closing event, securing the lockbox from access with the credential.

A computer system for ensuring physical access control of a lockbox, the computer system comprising:

• a processor(s) set;
• and
• a computer readable storage medium having program instructions stored therein;
• wherein:
• the processor(s) set executes the program instructions that cause the processor(s) set to ensure physical access control of a lockbox by:
• monitoring physical access of a lockbox under controlled access according to a contract governing control of the lockbox;
• generating an authentication of a user by determining a first biometric reading stored for reference matches a second biometric reading submitted for the authentication, the first biometric reading associated with a user having authority to gain physical access to the lockbox according to the contract;
• recording an identity of the authenticated user to a ledger accessible over a peer-to-peer network of parties to the contract, the ledger supporting the contract by linking access activity of the parties using cryptography, the authenticated user being the user for whom the authentication was generated;
• identifying a request for physical access to the lockbox submitted by the authenticated user;
• submitting the request to an administrator for acceptance, the administrator being an authorized party of the contract;
• responsive to receiving an acceptance from the administrator, providing to the authenticated user a credential permitting access to the lockbox;
• responsive to use of the credential and opening of the lockbox, recording to the ledger the request associated with the authenticated user and an access event initiated by the authenticated user;
• responsive to the lockbox being closed at a time after the access event is recorded, recording a closing event on the ledger;
• and
• responsive to the closing event, securing the lockbox from access with the credential.
