Cyber surveillance refers to the monitoring of online activities and communications through digital means. This can include tracking internet usage, analyzing social media interactions, and collecting data from emails or messages. Organizations, governments, and even individuals may engage in cyber surveillance to gather information for security, marketing, or research purposes. The tools used for cyber surveillance can range from software that analyzes web traffic to advanced algorithms that detect patterns in user behavior. While it can enhance security and provide valuable insights, it also raises concerns about privacy and the potential for misuse of personal information.
