Abstract
A method and system for ascertaining an object status of an object associated to an authenticity certificate. A first hashing result of an object identifier encoded within a decrypted first encrypted step certificate is extracted. A second hashing result is obtained from hashing the object to be authenticated. A third hashing result of an object identifier encoded within a decrypted second encrypted step certificate is extracted. A fourth hashing result is obtained from hashing the object to be authenticated. It is determining that the first hashing result is equal to the second hashing result and that the third hashing result is equal to the fourth hashing result, from which it is ascertained the object status of the object is that the object is an authentic object, a counterfeited object, or a stolen object. The ascertained object status is displayed on a screen of an authenticity verification equipment.
