AUTHENTICATION BY USING ONE TIME NUMBER DYNAMIC MAPPED INDIVIDUAL SERVICE PROVIDER

摘要

PURPOSE: An authentication method using a disposable number dynamically mapped in a service provider is provided to authenticate a service provided from each service provider by creating a disposable number according to seed acquisition rules and various number creation rules. CONSTITUTION: A wireless terminal(200) determines a j(1ΔjΔJ) number creation rule corresponding to an i service provider from J(J≥1) number creation rules(730). The wireless terminal acquires k(1ΔkΔK) number seed values which are inserted into the j number creation rule from K(K≥1) number seed values which are acquired through one or more resources(735). The wireless terminal creates a disposable number including N(N≥1) numbers by inserting the k number seed values into the j number creation rule(740). The wireless terminal creates disposable numbers(745). [Reference numerals] (130) Service control module; (200) Wireless terminal; (700) Recognizing a service by using disposable numbers; (705) Confirming a wireless terminal including an application; (710) Confirming operation of an application; (715) Operating an application; (720) Outputting an interface which selects an i service provider; (725) Selecting an i(1<=i<=l) service provider from l(l>=1) number of service providers through an interface; (730) Determining j(1<=j<=J) number generation rules corresponding to an i service provider of J(J>=1) number generation rules; (735) Acquiring k(1<=k<=K) number seed values which are inserted into a j number generation rule of an i service provider among K(K>=1) number seed values which are able to be acquired through a resource of a wireless terminal; (735) Process for acquiring one or more seed values through a communication resource of a wireless terminal; (740) Generating a disposable number of N(Nl>=1) digit by inserting k number seed values into a j number generation rule; (745) Outputting a disposable number; (BB) Is an application operated?; (CC,FF) Yes; (DD,AA) No; (EE) Are k number seed values acquired through one or more resources?;
