1. An identification device, comprising:
signature generation circuitry that generates a signature in which packet header information of packet data included in traffic data is correlated with a category label representing a category of an application corresponding to the packet data;
flow data generation circuitry that generates flow data from the packet data;
assigning circuitry that assigns a flow data label to the flow data on the basis of the signature and flow data header information of the flow data;
calculation circuitry that calculates a feature amount of the flow data; and
learning circuitry that learns a model that predicts a feature amount label from the feature amount of the flow data using the flow data label and the feature amount of the flow data to which the flow data label is assigned.
