Final answer:
Authentication requirements are covered by various statutes such as the Voter Identification Requirements by State, National Security Act, Patriot Act, Homeland Security Act, and War Powers Resolution.
Step-by-step explanation:
The requirements of authentication are governed by various statutes that depend on the specific context. For example, when it comes to voter identification, interested individuals can visit the National Conference of State Legislatures for an overview of Voter Identification Requirements which vary by state. In the broader context of government action, several statutes influence authentication in the realm of foreign policy and national security. Notably, the National Security Act manages how government information is shared and stored. The Patriot Act, enacted after the tragic events of 9/11, specifies what information the government can collect about individuals to protect national security. The Homeland Security Act of 2002 led to the establishment of the Department of Homeland Security, a consolidation of powers from various agencies to improve coordination which had been lacking before the 9/11 attacks. Another key legislation, the War Powers Resolution, delineates the balance of war powers between Congress and the President.
