Abstract: A computer system according to certain aspects uses past ticket usage data indicating a probability that a respective entity would personally use a ticket issued to them based on a history of past ticket usage. A ticket controller can respond to ticket requests by determining whether a ticket should be issued to a requesting entity based on the past ticket usage data associated with the requesting entity's profile, and if so issue a ticket to the requesting entity in electronic form. The system can receive a ticket use notification and update the past ticket usage data associated with the requesting entity's profile based on the ticket use notification, where the updated past ticket usage data conveys whether the requesting entity presented the ticket themselves.

Abstract: A computer system for tracking assets comprises an asset tracking system, a digital identity system and a computer interface. The asset tracking system comprises electronic storage and a profile manager. The electronic storage of the asset tracking system holds an initial profile of an asset in association with an asset identifier of the asset. The digital identity system comprises a profile manager and electronic storage configured to hold profiles of entities. The computer interface is configured to receive asset transfer notifications. Each asset transfer notification identifies the asset and a respective entity participating in a transfer of the asset. The profile manager of the asset tracking system is configured to, each time an asset transfer notification is received, create in the electronic storage a new profile of the asset comprising an identifier of the respective participating entity. The new profile of the asset is stored in association with the asset identifier.
