I wonder how the next piece will evolve? How can seamless travel become reality? How can the data, once enrolled in a trusted traveller platform, really be exchanged seamlessly between the various stakeholders globally, in particular given the stakeholders different interests. How can we implement the data privacy principle of accountability, data ownership and transparency across an ecosystem that is so globally fragmented? Besides the Trusted Traveller concept...will there be a "Trusted Data Controller" concept upholding the data privacy principles? Will governments need step in to create a global framework? Surely no private entity can be trusted with such sensitive data!
