Abstract: An identity management platform comprises a cloud based API layer, an identity service and an ABIS biometric service. The identity service acts as a broker engine integrating travellers, operators, airports and governments, enabling the sharing of identities. The identity service manages travellers' identities and enrols travellers, receiving biometric information and assigning unique identifiers to travellers. A biometric service communicates with the identity service and receives biometric data such as facial data from a traveller's identity document. They also receive biometric data which is supplied by the traveller, for example by taking a photograph at the airport. The ABIS matches the two sets of biometric data and, if the match is successful, associates the unique ID generated for the traveller with the biometric data captured by the traveller.
