Title: Innovations by Xiaoguang Liu in IoT Device Classification

Introduction

Xiaoguang Liu is an accomplished inventor based in San Ramon, CA. He has made significant contributions to the field of Internet of Things (IoT) device classification, holding 2 patents that focus on efficient packet processing and device identification.

Latest Patents

His latest patents include "Kernel space based capture using intelligent packet selection paradigm and event output storage determination methodology." This invention provides systems and methods for efficient kernel space packet processing and IoT device classification. The technology allows a computer system to receive packets in kernel space and determine their destination. If the packet is intended for the system, it is forwarded to user space. If not, the system checks if the packet is associated with IoT device protocols. Upon confirmation, header information is extracted, facilitating IoT device detection processing. The system can then create a variable-length feature set for each identified TCP or UDP flow, using a machine learning model to infer whether the flow represents IoT or non-IoT device communication.

Another notable patent is "Internet of things (IoT) device identification on corporate networks via adaptive feature set to balance computational complexity and model bias." This invention also focuses on efficient packet processing and IoT device classification. It involves receiving packet header information for multiple packets and identifying TCP or UDP flows between devices. For each flow, a variable-length feature set is created, and a machine-learning model is applied to classify the communication as either IoT or non-IoT device communication.
