The widespread application of artificial intelligence technology in intelligence analysis, it brings convenience to decision-making and services, but the risk problem brought by intelligent algorithms is also particularly prominent. The innovative research on the risk management mechanism of intelligent intelligence analysis algorithms is systematic, The main means of scientifically preventing and resolving the security risks brought by algorithms have important practical significance. The risks faced by intelligent intelligence analysis algorithms are studied and explained. the risk governance framework of blockchain empowerment intelligent intelligence analysis algorithms is analyzed from three perspectives: user level, mechanism level and process level. The risk of blockchain and intelligent intelligence analysis algorithms is combined to form a governance mechanism. Analyzes the core connotation of the mechanism from four aspects: the consensus agreement enabling algorithm risk early warning mechanism, the smart contract enabling algorithm risk monitoring mechanism, the incentive rule enabling algorithm risk autonomy mechanism and the time stamp enabling algorithm risk backtracking mechanism, aiming to provide decision-making and reference for the government and the intelligence work organization algorithm risk governance.
