Latest Patents

One of Xiaoyi Duan's latest patents is titled "IoT device identification by machine learning with time series behavioral and statistical features." This invention discloses a method for identifying IoT devices based on their packet flow behavior using machine learning models. The process involves receiving information associated with the network communication of an IoT device and determining whether it has been previously classified. If not, a probability match for the device against a behavior signature is assessed, which includes time series features for the application used by the device. Based on this probability match, a classification is provided to a security appliance to apply relevant policies.

Another notable patent is "Detecting behavioral change of IoT devices using novelty detection based behavior traffic modeling." This invention features an anomalous behavior detector designed to identify novel behavioral changes in devices based on network traffic data. The detector employs the local outlier factor (LOF) algorithm with novelty detection. After initial semi-supervised training with a dataset representing stable device behaviors, the model continues to learn from live network traffic data. The feature vectors used represent the stability or similarity of network traffic variables, which serve as device identifiers and behavioral indicators.
