PETs, or Privacy-Enhancing Technologies, are tools and methods designed to protect personal information and enhance user privacy online. They help individuals control their data and limit how much information is shared with others, especially on the internet. Examples of PETs include encryption, which secures data, and anonymizing services, which hide users' identities. These technologies are increasingly important as concerns about data breaches and surveillance grow. By using PETs, individuals can safeguard their sensitive information from unauthorized access and maintain their privacy while navigating the digital world. This is crucial in an era where data is often collected and analyzed without consent.
