Security improvement of the ID system using a cell phone

A personal identification method that is called as the electronic ID is proposed by using a cell phone. The cell phone displays a face image, character data and a two-dimensional including personal identification data. Although plastic cards, magnetic stripe cards and smart cards are used as ID (identification) cards, the risks to lose these cards are large. A cell phone of the electronic ID can securely display all of the identification data on its color display. The prototype of the electronic 10 system using a cell phone, a Web server and a manager's portable computer to identify each user is implemented and experimented.
