Introduction

Yuminobu Igarashi, an accomplished inventor based in Musashino, Japan, has made a significant impact in the field of detection technologies. With a total of four patents to his name, Igarashi focuses on developing innovative solutions that contribute to enhanced security and device management.

Latest Patents

Igarashi's latest patents showcase his expertise in detection devices and methods. One notable invention is a detection device that obtains both network logs and host logs of a device. This device transforms the network log into a network feature value suitable for input into a multimodal generative model, which generates output data based on multiple latent variables represented by random variables. Additionally, it converts the host log into a host feature value, also inputtable to the generative model. By processing at least one of these feature values, the device calculates output data and identifies abnormalities in the device using an anomaly score derived from the output data.

Another significant patent details a control device and method aimed at improving DNS security. When an attack is detected, the controller samples attack-target addressed DNS replies received by a border router. It subsequently adds the transmission-source IP address of these replies to a blacklist, ensuring that any future packets from the blacklisted IP are discarded. The controller also establishes settings to exclude certain DNS replies from being discarded, thereby maintaining the effectiveness of security protocols.
