A authentication method for providing augmented reality (AR) information includes acquiring an image of a real-world environment including a target object; identifying the target object in the acquired image; requesting data related to the target object to a server; receiving encoded data related to the target object from the server; authenticating the encoded data; and outputting the authenticated data as AR information. A terminal to perform authentication to provide AR information includes a communication unit to receive and transmit a signal from and to a server; a display to output a target object and data related to the target object; and a controller to receive encoded data related to the target object from the server, to authenticate the encoded data, and to output the authenticated data on the display.
