Abstract: With the rapid development of financial informatization, the risk management of financial information system is becoming more and more important. The core of risk management is risk assessment, which requires scientific assessment of information system risks of financial institutions. This paper analyzes the results of BP artificial neural network by using the artificial neural network algorithm under the condition of big data, and uses the information systems developed by 60 financial institutions at the end of 2021 as samples for experimental verification. The experimental results show that the artificial neural network has high correlation and low relative error, and the numerical fitting effect is good. The risk assessment model of financial information system based on artificial neural network is feasible, which provides a powerful demonstration for the application of big data and artificial neural network in financial information system.
