1. A method for providing Internet resource address information using a dynamic QR (Quick Response) code, the method comprising:
receiving, by a QR code management module, a first protocol request and extracting a QR code label identification number included in a first URL from the received first protocol request;
forwarding, by the QR code management module, a second protocol request to a redirection link module after looking up redirection link address information from a QR code identification table using the QR code label identification number as a search key;
extracting, by the redirection link module, redirection code information included in a second URL from the forwarded second protocol request; and
looking up, by the redirection link module, Internet resource address information from redirection link table using the extracted redirection code information as a search key,
wherein the QR code management module refers to the QR code identification table to search for a row containing a value identical to the extracted QR code label identification number, looks up the redirection link address information from the searched row, and forwards the second protocol request to the redirection link module located at the looked-up redirection link address information,
wherein the QR code management module checks the usage status information from the searched row in the QR code identification table, records the usage status information as “TRUE” and forwards the second protocol request to the redirection link module when the checked usage status information is “FALSE”, and rejects the first protocol request sent by the user terminal device when the checked usage status information is “TRUE”, and
wherein the QR code management module generates a QR code label identification number, adds a row to the QR code identification table which includes the generated QR code label identification number, the corresponding redirection link address information, and the usage status information initialized as “FALSE”.
