There is provided a function license authentication method and system capable of preventing the illegal creation of a license key. A function license authentication method comprising: a step in which an authentication server generates a function code based on order in which functions used have been coded; a step in which a user transfers an equipment-specific code to the authentication server; a step in which the authentication server generates a first license key based on the function code and equipment-specific code; a step in which the user inputs the coded order to the equipment; a step in which the user acquires the first license key from the authentication server and inputs the acquired first license key to the equipment; a step in which the equipment generates a function code based on the coded order that has been input thereto and further generates a second license key based on the generated function code and equipment-specific code; and a step in which the equipment compares the first and second license keys and determines that authentication is successfully completed when the first and second license keys coincide with each other.
