Trust and inclusion are interrelated concepts. Trust is relational and contextual, involving contractual, emotional, and transactional elements. It is easier to revoke trust than to rebuild it. Digital trust is more transactional, with rules that are less complex than interpersonal trust. Inclusion requires trust between individuals and service providers. Vulnerable populations like children, women, minorities, immigrants and the disabled often lack credentials needed for digital identification and authentication systems. Emerging technologies like blockchain and trustmarks may help establish digital identities and assess identity providers to better include vulnerable groups.
