Abstract: The rapid development of artificial intelligence (AI) and big data has ushered us into a society of algorithm. Algorithm has penetrated into every aspect of social economy, life and management. However, algorithm is not an absolutely objective and neutral technology. The  bias and problems generated during algorithm operations are essentially the reflections of social prejudices in the age of AI. These bias and problems cause harm to the society, infringing on the right of equality, privacy and posing threats and even damage to data security. Therefore, instead of being confined to the “technological utopia” in algorithms, we should get a better understanding of where algorithm bias are generated and what legal and factual risks they will bring about so as to reduce their hazards on social order given their uncertainties. It is necessary to construct a risk prevention and control system of law and comprehensive governance in time, thus bringing the prevention and control of algorithm bias into regular social governance system.

Key words: artificial intelligence, algorithm bias, prevention and control in governance
