Comprehensive overview of global data privacy regulations, with a particular focus on the General Data Protection Regulation (GDPR) and its international influence. Several documents detail the principles of "Privacy by Design" and its implementation through strategies like minimisation and transparency, mandated by GDPR Article 25. The texts highlight the significant enforcement of GDPR, listing major fines imposed on large corporations such as Meta and Amazon for violations involving data transfer, inadequate consent, and child data processing, alongside warnings about potential personal liability for executives. Finally, the sources compare the GDPR to other international privacy frameworks, including Brazil's LGPD and China's PIPL, noting their similarities, extraterritorial reach, and the global trend toward stricter data protection laws in the age of Artificial Intelligence and big data.
