Provided are a smart card device, a device for generating a virtual code for authentication, a method of generating a virtual code for authentication using the same, and a server for verifying a virtual code for authentication. The method includes transmitting time data to a card upon tagging of the card in which an IC chip has been embedded, receiving, from the card, a virtual code for primary authentication generated based on the time data, generating a virtual code for secondary authentication by using the virtual code for primary authentication, transmitting at least one of the virtual code for primary authentication and the virtual code for secondary authentication to a server, and requesting the server to perform verification on the at least one.

Smart card device, device for generating virtual code for authentication, method of generating virtual code for authentication using the same, and server for verifying virtual code for authentication

A method, program, and device for authenticating user setting information by using a virtual code are proposed. The method includes: receiving, by a virtual code verification means, a virtual code; searching, by the virtual code verification means, a storage location of each of a plurality of UIDs on the basis of the virtual code; verifying, by the virtual code verification means, the virtual code on the basis of the plurality of searched UIDs; and performing, by the virtual code verification means, authority authentication on the basis of the plurality of searched UIDs.

Method, program, and device for authenticating user setting information by using virtual code

Disclosed are a smart card for generating and providing a virtual code, and method and program therefor. A method for generating and providing a smart card-based virtual code includes receiving, by the smart card, first power from the outside, generating, by the smart card, the virtual code based on a time count using the first power, and providing, by the smart card, the virtual code to the outside, in which the virtual code is a virtual card number or a virtual token, generated as a code matching an actual card number by a virtual code generation function previously stored in the smart card, and used to search for the actual card number in a financial company server or a virtual code verification server, the time counter is counted and measured from an initial time value provided at the time of manufacturing the card by a time measurement module included in the smart card, and the time measurement module includes a clock that measures the time data and a clock battery that supplies second power to the clock.
