Summary of research projects
Iris Recognition Technology (2000-2001): When I headed the project 'CyberCommerce System for Online Internet Business' and 'ebXML Framework for International Open Business Service', I had technical issue regarding remote identification without providing a user-ID and password. We assumed that hackers stealing people's user-ID and password when a user enters them and transmits them by way of Internet. The idea of using biometric information came to me. I and my staff started to analyze user needs and technical limitations. After 6 months of endurance and perspiration, we announced an efficient iris recognition system. Soon, this technology was transferred to SENEX, Inc. After their commercialization project with my team, the brand name 'True Eye' was born. SENEX, Inc. sold 'True Eye' for $2.5M. Here's a reference web site.
Embedded Sensor Network Platform Technology (2004-2005): At the dawn of the 21st century, fully connected societies like Korea started to move forward ubiquitous computing. Naturally, sensing space was one of the hot research topics in Korea, and soon, sensor networks were spotlighted. In 2004, I and my staff designed and implemented embedded type sensor network platform. It contained sensor hardware platform, sensor device driver, sensor middleware, and application programming interfaces. For wireless communication, we provided sensor platform with ZigBee and WiFi interfaces. In 2005, this technology was transferred to Huins, Inc. which sells sensor platforms as educational kits.
Java Card Developer's Toolkit (2001-2002): One of the hot issues in 1999-2000 was electronic cash in Korea. At that time, I was a team leader of Electronic Payment Research Team at ETRI. after reviewing the needs and technical barriers of electronic cash, I and my colleagues decided not to use traditional magnetic card as electronic cash because of its vulnerability. After benchmarking of MONDEX and other commercial approaches, I and my colleagues chose Java card as a next generation smart card that can store electronic cash safely. I and my team staff focused on developing the toolkit for Java card application developers. After 8 months of endeavor, my team announced 'Java Card Application Developer's Toolkit' in 2001. It was featured and we had to implement sample source code for better understanding of ordinary people in Korea. A few months later, this technology was transferred to Shinwon, Inc. Unfortunately, in 2001, this technology was not commercialized due to the delay in establishing the relevant policy for the specifications of electronic cash and smart cards.
