A Study on the Legal Regulation of Artificial Intelligence and Big Data Crimes in the Context of Smart Cities

In the construction of smart cities, while artificial intelligence and big data technologies improve governance effectiveness, they also give rise to new crimes such as data leaks, algorithmic discrimination, and system attacks, posing challenges to residents' rights and urban security. Current laws and governance mechanisms lag behind, with unclear responsibility determination and insufficient regulatory measures becoming prominent. Drawing on the smart city technology ecosystem, this article analyzes the types and characteristics of these crimes and the challenges in addressing them. Drawing on domestic and international experience, it proposes regulatory approaches from the perspectives of legislation, judicial practice, ethics, and multi-faceted governance, providing theoretical and practical guidance for achieving the safe and sustainable development of smart cities.
