A mobile phone identification method using packet arrival time in web access for user authentication

Abstract

A new method of identifying a user’s mobile phone for user authentication is proposed. When the authentication server receives packets from the mobile phone, it is identified by the packet arrival time. The authentication in the server is based on the change in packet arrival time when the mobile phone receives a call to the user’s telephone number registered with the server. This paper describes how the transmission delay characteristics yield the identification data; the viability of the proposed method is verified for a wide variety of mobile phone wireless environments in which mobile phones are used.
