confirms Sullivan's argument and unfolds the new legal concept involving database identity and transaction identity. Database identity is the collection of data that is registered about an individual within the databases of the scheme and transaction identity is a set of information that defines the individual's identity for transactional purposes. Although there is reliance on the verification of identity, none of the processes used are entirely trustworthy.

Also, strict policies against money laundering mean that some services, such as money transfers need a stricter level of validation of digital identity. Digital identity in the national sense can mean a combination of single sign on, and/or validation of assertions by trusted authorities (generally the government). Countries or regions
