In what year was the Privacy Act passed, marking a significant definition of privacy?

The Privacy Act was passed in 1974, marking a pivotal moment in the evolution of privacy rights in the United States. This legislation was a response to growing concerns about the government's collection and handling of personal information, particularly in the context of advancements in technology that allowed for more extensive data collection and surveillance.

The Act established important guidelines for federal agencies regarding the collection, use, and dissemination of personal data, aiming to protect individual privacy while ensuring that data practices were transparent and accountable. It provided individuals with the right to access and correct information held about them and restricted how that information could be used or shared.

The other years listed do not align with the enactment of significant privacy legislation specifically known as the Privacy Act. Each of those dates pertains to different events or legislation unrelated to the constitutional framework for privacy protections that the Privacy Act established.
