Title: Innovator Hongliang Liu: Pioneering Advances in Domain Security

Introduction

Hongliang Liu, an inventive mind based in Campbell, CA, is recognized for his contributions to domain security and anomaly detection in DNS requests. With a total of four patents to his name, Liu has made significant strides in enhancing the methodologies used in cybersecurity.

Latest Patents

Among Liu's most notable innovations is a patent for a "System for Domain Reputation Scoring." This advanced system involves computer-implemented methods that aim to provide a comprehensive reputation score for domain names. The process begins with receiving a request for a reputation score and includes the extraction of various data features related to the domain name. A machine-learning classifier then uses a graph database that features vectors tied to reference domain names and their owners to compute the reputation score. This score ultimately reflects the probability that a domain name is linked to malicious activities.

Another significant patent addresses "Analyzing DNS Requests for Anomaly Detection." This invention focuses on a computer-implemented methodology for detecting anomalies in DNS requests generated over a specific timeframe. By analyzing these requests and calculating count values for DNS data fragments, the system identifies anomaly trends, particularly when certain count values exceed predefined thresholds.
