Abstract: A method of digitally authenticating a user's health status, the method comprising: sending a certificate representative of health data associated with a user to a verifying entity; the verifying entity carrying out verification on the certificate and, if the certificate is verified, providing a credential based on the verified certificate; and authenticating the user associated with the health data based on the credential.

Abstract: An article tracking system and method are provided. The system includes a checkpoint identifier associated with a checkpoint in a predefined journey of a bag from an origin to a destination location. The system includes a mobile application stored on the mobile device. The mobile application can be configured to, on arrival of the bag at the checkpoint, generate a tracking message that comprises the checkpoint identifier and a baggage identifier associated with the bag, the mobile application further configured to transmit the tracking message. The system includes a tracking database configured to receive and store the transmitted tracking message, to thereby record the location of the bag.

Abstract: An apparatus is provided for verifying a plurality of cryptographically signed user electronic records using a corresponding cryptographic proof. Cryptographic keys for verifying the plurality of user electronic records, and corresponding user electronic record schemas are cached in a local data store. The apparatus obtains up-to-date copies of the cryptographic keys and schemas for caching from a remote data store when the remote data store is accessible by the apparatus over the internet. Upon receipt of the data from the user device, when the remote data store is not accessible, the apparatus is configured to identify the cached cryptographic key and schema corresponding to the received cryptographically signed electronic record and cryptographic proof; and determine a verification result for the cryptographically signed electronic record based on the cryptographic proof and the identified cached cryptographic key and schema. An indication of the verification result is then output from the apparatus.

Abstract: A system and method of delivering a bag to a final destination are described. The system receives a customer request to re-route the bag, the customer request including a final destination and a unique identifier associated with customer-related information. The system identifies the bag based on the customer-related information and re-routes the bag from a first destination to a further destination. The system sends a delivery request to a delivery service provider for the bag to be delivered from the further destination to the final destination.

Abstract: An article tracking system and method are provided. The system includes an article identifier, a location identifier, a mobile application stored on a mobile device, and a cloud platform. The mobile application combines article information from the article identifier and location information from the location identifier into a data packet and transmits the data packet to the cloud platform for storage. Creating and sending a data packet for each of a plurality of locations enables to system to record the location history of the article over time.

Abstract: A system and method for tracking baggage on cruise liners are provided. A baggage tag is created which includes a unique baggage identifier and a unique passenger identifier that has been allocated by a reservation system. The identifiers are associated and stored in a baggage message. The baggage tag is affixed to an item of baggage and as the passenger checks in the item the tag is scanned and the bag validated and the status of the item in the baggage message is updated. When the passenger boards the ship, they scan a touch point with a mobile communications device which indicates that the item of baggage can now be delivered to their cabin. Shortly before arrival at port, the bags are loaded into a baggage container for unloading at the port and each bag tag is scan and associated with a scanned container identifier. The container is notified to the passenger through a message sent to their mobile communications device.
