8. Confidential Appendix-1 Technical Characteristics “ Match-On” Type to protect the personal Iris Data Under the current data base system, the information data to differentiate a person from the others should be stored in data base of a PC as so called ‘Store-on Type’. For example, Fingerprint data should be stored in DB of the PC. The fingerprint data input from terminal should be compared with the one in the DB. However, this system still has bunch of risks to lose the personal data by illegal access like hacking. In order to protect the personal Iris Data safe, we introduced ‘Match-on’ technology in Iris Identification Mouse. All the processes to identify the iris are done only in the Mouse and the Iris Data should be stored and compared only in the mouse without being processed in the PC. The personal Iris Data could be created, compared and transacted only in the Mouse so that the Iris data would not fall out. 7
