Abstract: An object of the present invention is to provide an authorization device that enables payment approval processing according to a country where a communication terminal is located. An authorization server 100 includes a customer information database that stores a card number of a credit card being a payment means and a communication terminal 300 being a user terminal in association with each other. A location based authorization determination unit 102 determines legitimacy of a payment with a credit card on the basis of whether location country information based on location registration of the communication terminal 300 when the payment with the credit card is made and country information (payment country information in an authorization request) based on a location of an affiliated store (store) where the payment with the credit card is made satisfy a predetermined condition or not. A authorization control unit 101 transmits a determination result about legitimacy of the payment to an affiliated store 200.

Abstract: An object of the present invention is to provide an authorization device that enables payment approval processing according to a location of a user terminal without need for a positioning function. In an authorization server 100, a location based authorization determination unit 102 acquires, from a location information DB 400, location information based on location registration of a communication terminal 300 being a user terminal, and determines whether a location relationship between location information of the communication terminal 300 when a user makes a payment and an affiliated store 200 where the user makes the payment satisfies a predetermined condition (e.g., the location relationship is within a predetermined distance). When it is determined that the predetermined condition is satisfied, the payment by the user of the communication terminal 300 is allowed.

Abstract: Provided is an authorization device that enables approval of a user's payment transaction with no need for separate verification by telephone or the like. In an authorization server (100), a traffic based authorization determination unit (102) determines legitimacy of payment by a user terminal (300) in an affiliated store server (200) being a payment server on the basis of traffic information containing access time of the user terminal (300) and server information being an access destination. Then, an authorization control unit (101) performs processing for enabling a payment transaction on the basis of this determination result.
