The ID system using a cell phone with the verification and security

Abstract

ID (identification) cards are used for proving the identity of each person. In many cases, the ID card is realized by using an IC plastic card. The student ID (identification) card is used for proving the studentship of each student in a college or a university. This paper proposes a method to realize a student ID electronically on the screen of a cell phone. The original student ID data are stored in a personal computer (PC) of the administrator. The student ID is realized by using a protected file sent to each student's cell phone. After receiving the student ID, each student can use it without communicating the PC of the administrator. The validity of the student ID using a cell phone is verified by the inspector's cell phone including the verification software. The proposed student ID has a merit that it can be used for most of handset models of cell phones and cell phone carriers. The prototype of the student ID using a cell phone is constructed and evaluated. The proposing student ID system can be extended for the general purpose ID system such as a company ID card system.
