1. A method for supporting identity management of travelers in an airport using a distributed ledger system, the distributed ledger system including a global identity blockchain and several security blockchains, the global identity blockchain being accessible by entities of the distributed ledger system, and a respective security blockchain of the several security blockchains being employed for a predetermined flight segment, the respective security blockchain being accessible only by entities of the distributed ledger system that are involved in the predetermined flight segment, the method comprising:
receiving, by the global identity blockchain, a registration request from a traveler via a traveler device, wherein the registration request includes a commitment for identity data that is uploaded by the traveler in a secure cloud storage,
recording the commitment in the global identity blockchain,
receiving, by the global identity blockchain, a result of an identity verification with respect to the traveler from a verifier entity,
recording the result in the global identity blockchain,
receiving, by the respective security blockchain, a ticket registration transaction issued by an airline entity, wherein the ticket registration transaction comprises a unique traveler ID of the traveler, and
issuing, by the respective security blockchain, an access control list update upon reception of consent by the traveler in order to allow one or more entities to have access to the identity data of the traveler stored in the secure cloud storage.
