Online privacy involves controlling what personal information is revealed over the Internet and who can access it. While online privacy is possible with common sense practices like limiting what information is shared, comprehensive privacy laws and protections are also needed. Efforts to protect online privacy include setting limits on government access to data, designing technologies with privacy in mind, and educating users, especially children, about safe practices. However, risks still exist like tracking cookies and spyware that can compromise privacy without users' knowledge.
