US Patent 11348115 Method and apparatus for identifying risky vertices

The present specification provides a method for identifying risky vertices, including: constructing multiple medium networks, each of the multiple medium networks being constructed from one or more black seeds of the same type and including vertices and media connected to the vertices; determining a first risk value of each vertex based on a quantity of upper-layer media connected to the vertex and a quantity of risk conditions that the vertex meets; determining a final risk value of each vertex based on a quantity of overlapping times of the vertex in a stacked medium network structure and the first risk value; and determining a high-risk vertex based on the final risk value.
