IDs Not That Easy highlights some of the challenging policy, procedural, and technological issues presented by nationwide identity systems. In the wake of the events of September 11, 2001, nationwide identity systems have been proposed to better track the movement of suspected terrorists. However, questions arise as to who would use the system and how, if participation would be mandatory, the type of data that would be collected, and the legal structures needed to protect privacy. The committee’s goal is to foster a broad and deliberate discussion among policy-makers and the public about the form of nationwide identity system that might be created, and whether such a system is desirable or feasible.
