ABSTRACT:
A key authentication device and method which, through the use of user-unique information, prevents the improper use of software. The key authentication device is equipped with a software storage medium for storing software with encoded characters, graphs, images, or sound, and, when using the software of this software storage medium, employs an input characteristics detection section for detecting the characteristics of input operations performed by a user, a management center for encoding input characteristics detected by the input characteristics detection section and for generating consent information, and a comparison section for comparing the consent information generated by the management center with the input characteristics detected by the input characteristics detection section.
