Abstract
A device estimation system (1) includes a packet analysis model learning apparatus (20) for generating a packet analysis model (200), a waveform analysis model learning apparatus (30) for generating a waveform analysis model (300), a traffic information collection apparatus (50) for collecting packets of a target device (5), and a device estimation apparatus (10) for extracting a statistical value and a keyword from a packet, generating candidates for a manufacturer and a functional category of the target device (5) using the packet analysis model (200), generating traffic waveform information from the packet, narrowing down the candidates using the waveform analysis model (300), specifying the manufacturer and functional category of the target device (5), and transmitting the same to the analysis model management apparatus (40).
