Determination method, determination system, determination device, and program
The present invention addresses the problem of providing a technique for determining the authenticity of a product without requiring a special device such as an integrated circuit (IC) tag. A means for solving this problem according to the invention is characterized by determining the authenticity of a target product on the basis of the validity of the association between the body of the product and a surface-treated component that is mounted to the body and that has been validated.
1. An authenticity determining method, comprising:
storing an extracted image feature and registered trademark information about a registered trademark in association with each other,
wherein the extracted image feature includes a random pattern in a predetermined region that can be identified in an individual group or in units of individuals;
confirming, by collating the extracted image feature and the registered trademark information with a stored image feature and a stored registered trademark, whether a validity of a portion mounted on a body of a product is legitimate;
determining, based on the confirmation, whether the extracted image feature and registered trademark information match the stored image feature and stored registered trademark; and
further determining, based on the match, the authenticity of the product.
2. The authenticity determining method of claim 1 , further comprising:
determining, if there is no match, whether the product is counterfeit.
3. An authenticity determining apparatus comprising:
one or more processors configured to:
store an extracted image feature and registered trademark information about a registered trademark in association with each other,
wherein the extracted image feature includes a random pattern in a predetermined region that can be identified in an individual group or in units of individuals;
confirm, by collating the extracted image feature and the registered trademark information with a stored image feature and a stored registered trademark, whether a validity of a portion mounted on a body of a product is legitimate;
determine, based on the confirmation, whether the extracted image feature and registered trademark information match the stored image feature and stored registered trademark; and
further determine, based on the match, the authenticity of the product.
4. The authenticity determining apparatus of claim 3 , further comprising:
determining, if there is no match, whether the product is counterfeit.
5. An authenticity determining system configured to,
one or more processors configured to:
store an extracted image feature and registered trademark information about a registered trademark in association with each other,
wherein the extracted image feature includes a random pattern in a predetermined region that can be identified in an individual group or in units of individuals;
confirm, by collating the extracted image feature and the registered trademark information with a stored image feature and a stored registered trademark, whether a validity of a portion mounted on a body of a product is legitimate;
determine, based on the confirmation, whether the extracted image feature and registered trademark information match the stored image feature and stored registered trademark; and
further determine, based on the match, the authenticity of the product.
6. The authenticity determining system of claim 5 , further comprising:
determining, if there is no match, whether the product is counterfeit.
7. A non-transitory computer-readable medium having instructions stored thereon, that, when executed by one or more processors, causes the one or more processors to perform a method comprising:
storing an extracted image feature and registered trademark information about a registered trademark in association with each other,
wherein the extracted image feature includes a random pattern in a predetermined region that can be identified in an individual group or in units of individuals;
confirming, by collating the extracted image feature and the registered trademark information with a stored image feature and a stored registered trademark, whether a validity of a portion mounted on a body of a product is legitimate;
determining, based on the confirmation, whether the extracted image feature and registered trademark information match the stored image feature and stored registered trademark; and
further determining, based on the match, the authenticity of the product.
8. The non-transitory computer-readable medium of claim 7 , further comprising:
determining, if there is no match, whether the product is counterfeit.
