Abstract： On the basis of the block chain technology， a cross?domain authentication model for financial big data is proposed to solve the problem that biometric authentication technology is vulnerable to active attack. The security problems that might exist in the biometric authentication technology are pointed out by analyzing its some details. For these security risks， the technical details and authentication protocols of cross?domain authentication model based on block chain technology are designed， and the security of the model is analyzed in detail. The analysis and testing results show that this model has stronger portability and higher efficiency， which can resist man?in?the?middle attack and password guessing attack.
