For my senior thesis, Privacy & Security is a crucial topic toward my everyday experience. When I use any digital platform, I feel like always under surveillance throughout the digital platform. It makes me feel uncomfortable after I notice this behavior. This book is like a journal to explore privacy & security concepts and experimenting through typographies, posters, and patterns. After I finish this book, I feel like I learn something from the topic through the project. I like to explore more after I graduate.
