Written for middle-grade and older readers, Eyes and Spies looks at the way information and data about us is collected and used by individuals, governments, companies, and organizations. Each chapter covers one aspect of the subject, from data collection to computer surveillance to personal privacy. Arguments for both increased security and increased privacy are offered, which encourages readers to think critically about issues and decide for themselves. The book asks three simple questions: Who’s watching, and why? Where is the line between public and private? How can you keep your secrets to yourself? “Creepy Line” sidebars highlight controversial real-life scenarios and ask readers where they would set their own boundaries. Action Alerts encourage readers to find out more about how surveillance and data mining affects them. Other topics include how students are tracked at school; cyberbullying, and cyber safety. Color illustrations and a dynamic design make this an enlightening and engaging read.
