From the perspective of enterprise value enhancement,this paper provi des a new train of thought to solve the security risk of enterprise financial ma nagement system and realize the intelligent management of enterprise financial r esource elements.By using the authentication recognition algorithm constructed by block chain and deep confidence network to encrypt the security of enterprise financial system,a new dual-mode mechanism is proposed to optimize the securi t y strategy of enterprise financial information.According to the design scheme o f the model,firstly,the design scheme of the financial management system of th e intelligent company based on the blockchain is proposed,and the algorithm of recognition technology based on the deep confidence network is proposed.The rel iability and efficiency of the model are verified by simulating the attack and s ecurity state of enterprise financial system.
