Technology changes how individuals and societies understand the concept of privacy. The fact that someone has a new ability to access information or watch the actions of another does not justify doing so. Rather, advances in technology require citizens and policy makers to consider how privacy protections should be expanded. For example, when cameras first became available for commercial and private use, nations and citizens struggled over whether new laws should be enacted to protect individuals from being photographed without their permission. The reconsideration of privacy brought about by this new technology re-affirmed a distinction between private and public spaces. It was determined by most cultures that people automatically gave consent to being seen ― and thus recorded ― once they voluntarily stepped into a public space. Although some people might be uncomfortable with the spread of surveillance cameras, citizens in most cultures have adjusted to the fact that giving up the right not to be observed in these circumstances causes less harm to the community than failing to have surveillance.
