The invention, which relates to the technical field of
payment security, discloses a
payment-scene-oriented interaction intention identification and error
correction system comprising an input analysis module, an intention
simulation module, a dynamic decision module, a biological
verification module, an audit evidence storage module, and a cross-scene knowledge migration module. According to the method, multi-
modal data such as voice, texts, images and touch tracks are integrated, structured feature vectors are generated through a cross-
modal attention network, the problem of incomplete single-
modal coverage is solved, cross-
modal data consistency
verification is achieved based on a unified semantic
tag system, and the reliability of input sources is graded by combining equipment fingerprints and geographic positions, so that the reliability of the input sources is improved. A high-risk transaction protection capability is enhanced, a
generative adversarial network is utilized to construct a virtual
attack sample
library, attacks such as tampering with characters similar in shape and AI faking voiceprints are simulated, unknown threats are actively defended through
cosine similarity matching, a user historical behavior
statistical model is integrated, and known risks such as high-frequency small-amount transfer are passively intercepted. And a closed-loop
incremental learning continuous optimization model is supported.
