Title: Chi-Ren Shyu: Inventor in Data Mining and Authentication

Introduction

Chi-Ren Shyu is an inventor based in Columbia, Missouri, and is affiliated with the University of Missouri. His work includes inventions in data mining and user authentication. He holds 7 patents.

Latest Patents

“Frequent Pattern Mining on a Frequent Hierarchical Pattern Tree” describes a persistent tree-based data structure for mining frequent patterns. Its approach seeks to identify large, maximal patterns before their subsets, reducing computation time. The structure can be updated without rebuilding the entire tree and can run locally or across a distributed computing system.

“Visual Storytelling Authentication” presents a method for authenticating a user through personalized visual stories. A subject selects story-related images from among decoys, while gaze tracking can register selections without revealing them to an observer. The images may come from the user’s social networking profile, and the system can support different security levels by varying the numbers of story and decoy images.

Career Highlights

Shyu’s listed inventions address computational methods for discovering patterns in data and techniques for visual user authentication. His affiliation with the University of Missouri connects his work to a university research environment.

Collaborations

His listed coworkers include Matthew Nicholas Klaric and Grant Jason Scott.

Conclusion

Chi-Ren Shyu’s patent portfolio reflects work spanning efficient frequent-pattern mining and privacy-conscious visual authentication.
