In the digital age, our personal data is traded at prices that sometimes rival those of raw commodities. This mini book reveals how corporate intangible assets reached $80 trillion in 2024 and why the planet will store more than 200 zettabytes of information by 2025. It traces the explosion of advertising and data brokerage markets, the unprecedented value of medical and genetic records, and recent scandals such as the Change Healthcare and 23andMe leaks. It deciphers new laws (the Data Act, AI Act, and India's DPDP rules), dozens of U.S. state regulations and the record fines imposed on web giants. Drawing on up to date figures, it shows that cybercrime now costs trillions of dollars and that 81 % of small businesses were attacked in 2025. Beyond the diagnosis, the work invites readers to take back control - adopt privacy enhancing technologies, demand transparency and support balanced legal frameworks. An essential guide for understanding why our data is worth more than gold and how to protect this invisible treasure.
