Title:
AUTHENTICATION SYSTEM, AND INFORMATION RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/037453
Kind Code:
A1
Abstract:
In the present invention, a management device (181) calculates a user seed from access information transmitted from a token terminal (121) and a site seed allocated to a server (161), and registers the user seed in the token terminal (121). The token terminal (121) independently acquires, from the server, a shared seed shared with the server (161), calculates a key code from the shared seed and the user seed, and presents the key code to the user. When the user inputs the key code to an access terminal (141), the access terminal (141) transmits the request for which the key code is specified to the server (161). The server (161) acquires access information pertaining to the transmitted request, calculates a verification seed from the access information and the site seed allocated to the server (161), acquires a shared seed independent from the token terminal (121), calculates a verification code from the shared seed and the verification seed, and uses the matching of the key code and the verification code as a sign-in requirement.
