In the traditional world, the individual moves through differing process and policy environments in which varying policies govern their interactions with others. As one example, governments face the problem of enabling and managing cross-border travel and immigration. To address such requirements, government law and/or policy typically require citizens crossing national boundaries to possess passports that establish citizenship and identity. A passport links or "binds" some information about the individual (photograph, height, weight, age) to a specially designed physical document having a unique issuing authority and control number.
