The application discloses a
payment transaction
encryption verification system of multi-factor identity
authentication, relates to the technical field of
payment security authentication, and comprises a registration management, real-
time data acquisition, risk decision, multi-factor
authentication, token generation and transaction
verification module. When the
payment transaction is initiated, the
system dynamically calculates an
environmental risk index by analyzing network environment characteristics in real time, and selects a required
authentication factor combination for
verification in real time according to the index. The
system uses an
encryption synthesis
algorithm to fuse and calculate a plurality of generated independent authentication results and transaction
plaintext information, generates an encrypted payment token, and sends the token to a
payment gateway to complete decryption and comparison verification. The authentication strength is intelligently and dynamically adjusted according to the
environmental risk, the identity authentication evidence is deeply bound with the transaction information by using
cryptography, and the security and reliability of the transaction process are improved.
