Identification device, computer readable medium storing identification program and identification method

A non-transitory computer readable medium storing a program causing a computer to execute a process for identification, the process comprising:

• acquiring a collation fixed image that is an image of at least a part of a region, where a fixed pattern is formed, of a collation molded article that is a collation target, and a collation amorphous image that is an image of at least a part of a region, where an amorphous pattern that is a pattern formed when the fixed pattern is formed and formed on a region different from the region where the fixed pattern is formed, of the collation molded;
• referring to a storage unit that stores, as a registered image in advance for each of at least one mold, a pair of a registered fixed image, that is an image of at least a part of a region where a fixed pattern is formed, and a registered amorphous image, that is an image of at least a part of a region where an amorphous pattern is formed, of each of a plurality of molded articles formed by using the at least one mold;
• and
• specifying a mold that forms the collation molded article using the registered fixed image and the collation fixed image, and identifying whether the collation amorphous image matches the registered amorphous image of any of the registered images corresponding to the specified mold.
