INDIVIDUAL AUTHENTICATION METHOD USING INPUT CHARACTERISTIC OF INPUT APPARATUS BY NETWORK, PROGRAM THEREOF, AND RECORDING MEDIUM CONTAINING THE PROGRAM

摘要

An individual authentication method using input characteristic of an input apparatus of a computer by a network, its program, and a recording medium containing the program can extract an operation time of an input apparatus such as a keyboard by a computer user at an accurate timing. When the user performs an input via the keyboard (15), the computer (1) acquires the operation time that the user operates the keyboard (15) in kernel mode (8), i.e., an operation mode in which all the instructions of the OS (3) can be executed and transmits the operation time via the network (26) to an individual authentication server (28). The individual authentication server (28) analyzes the operation time to obtain the operation characteristic and compares the operation characteristic to the individual information in a database (29) of the individual authentication server (28) to authenticate the individual.
