A method for confirming whether a product is authentic is a method in which a terminal device receives an identifier of the tag device through a short distance communication from a tag device including a PUF (Physically Unclonable Function) circuit and a short distance communication circuit, Transmitting the first value to the tag device via the network, receiving from the server a first value that is specified based on the identifier, and transmitting the first value to the tag device, Receiving from the tag device a second value determined by applying the information included in the PUF circuit to the PUF circuit, and receiving from the server the authentication result determined using the identifier and the second value .
