The invention discloses a
network security verification method and
system for a
security system, and belongs to the technical field of
network security, and the method comprises the steps: obtaining a biological
feature recognition request triggered by a user on
terminal equipment, synchronously collecting dynamic behavior track data, and generating a behavior
feature code; inputting physiological
feature data and behavior feature codes in the biological
feature recognition request into a feature
verification model, when an output biological behavior
correlation index is lower than a first preset threshold value, triggering a dynamic
verification strategy adjustment instruction, generating a multi-dimensional verification superposition strategy, and executing at least two verification operations in the multi-dimensional verification superposition strategy, the verification result is input into the distributed
time synchronization node to generate an
encryption token; and when the synchronous matching degree of the
encryption token among different nodes exceeds a second preset threshold value, outputting a security verification passing instruction. According to the method, multi-
modal feature fusion, dynamic hierarchical verification and time-space
encryption technologies are adopted, replay attacks are prevented, an adaptive defense
system is constructed, and reliable
authentication of a high-security network scene is ensured.
