■ User Authentication Technology 2

We have adopted Cyber SIGN's Dynamic Signature^TM.

Cyber SIGN's Dynamic Signature^TM verifies the identity of a computer user by reading the behavioral biometrics of his/her hand-written signature. The patent-pending technology identifies and analyzes multidimensional data that are derived from the shape, speed, stroke, stroke time, and pen pressure of the signature as written on a reading device. Natural and intuitive, the technology has a major advantage over other types of biometric identity verification technologies. I'ts the fact that the hand-written signature has already been used all over the world as a common identity verification method. This time-proven trust and wide acceptance combined with the state-of-the-art and yet user-friendly features are expected to drive this technology into the biometric security system of choise all over the world.
User Authentication Technology 2

■ Electronic Documents Notarization Technology

J-Notary uses a special encryption algorithm "MD-5 (Message Digest Five)", which is embedded in a JAVA applet and transmitted to the user, to generate a hash. The hash is often compared to the fingerprint of an electronic document in that it is virtually impossible to find the same hash in two different documents. Another characteristic of the hash is its one-way reproductability, which means that you cannot reproduce the original from its hash, just as you cannot reproduce a human from his/her fingerprint. A digital time stamp is attached to the hash value for added security and time reference purposes.
