Research on Group Risk Security Decision Based on BP Neural Network Algorithm

Aiming at the uncertainty and diversity characteristics of risk assessment objects in group decision making, this paper proposes an information security risk assessment method based on BP neural algorithm. The paper gives a detailed risk assessment process and evaluation method for group decision-making security. The established group decision-making risk assessment system adopts the BP neural network method, which is a non-linear method, without obvious subjective components and human factors, making the evaluation results more effective and more objective. The example shows that the calculation results are close to the success story results
