Abstract
A code image is acquired by photographing a code as an authentication target. An extraction area is set within an area of the code shown in the code image. An image feature extracted from the extraction area is acquired as an extraction image feature. The image feature extracted from the extraction area of the code which is a genuine product is prepared and registered in advance as a registration image feature. An authenticity of the code as the authentication target is determined based on a verification between the extraction image feature and the registration image feature.
