Interest in PKI&＃39;s method of information security and its continuously expanding limits of application is rapidly rising. Especially, PKI&＃39;s methods in the fields of internet and smart card application have reached a great turning point.PKI has been established originally to maintain the system for secure internet business environment through the creation, distribution, and management of PKI&＃39;s cryptograph and authentication techniques. But cryptograph key management has been a important issue.Recently with regard to key management, portable devices for storing private security information have been produced in various forms. Hence, domestic security companies have produced portable storage devices of USB method in accordance with increasing need of personal information for person-verification as various financial business and electronic commerce has been expanding through the internet.Financial areas and EC companies are recently going to buy portable storage devices of USB method in bulk. But also general USB token like magnetic card executing person-verification by password is little secure in the aspect of security.We have researched methods of treatment in hard-ware on the base of biometric verification and have developed Touch Key and Touch Disk.Touch Key and Touch Disk are a method of On-Token unlike the method of Match-on-Token and can apply biometric security technique by attaching embedded fingerprint sensor into the USB module. Adaptability and portability is very excellent, because any system supporting USB port can easily apply. Also, the existing system can be used without special change.We will continuously develop special solutions which perfectly combine H/W with S/W in biometric security areas with the best technology and reliance on your information. Also, we promise that we will do our best to improve skill levels in information security areas onto the highest level.
