We are pleased to announce that 2025 International Conference on Artificial Intelligence Security and Governance (ICAISG 2025) will be held in Hangzhou, China during December 12-14, 2025. It is sponsored by Hangzhou Dianzi University, China, hosted by School of Cyberspace, Hangzhou Dianzi University, China, assisted by Sino-France Joint Laboratory for Digital Media Forensics of Zhejiang Province, China. In recent years, artificial intelligence (AI) technology has experienced explosive growth, profoundly reshaping human society—from the rapid iteration of generative AI like ChatGPT to deep applications in fields such as autonomous driving and smart healthcare. However, this technological leap has also brought increasingly prominent security risks and governance challenges: algorithmic biases may exacerbate social inequality, deepfake technology threatens information security, the lack of transparency in AI decision-making systems triggers trust crises, autonomous weapon systems harbor potential security risks, and the long-term development of Artificial General Intelligence (AGI) may even introduce unpredictable systemic risks. In light of this situation, the convening of 2025 International Conference on Artificial Intelligence Safety and Governance holds significant strategic importance. It aims to establish a global dialogue platform involving multiple stakeholders, promote the creation of an inclusive and balanced international governance framework, harmonize technical standards and regulatory policies, foster positive interactions between safety research and industrial innovation, and collectively guide AI technology toward trustworthy, reliable, and controllable development.
