Patent attributes
An information processing apparatus includes one or more processors to acquire a shape characteristic of a target entity; determine similarity between the shape characteristic of the target entity and a shape characteristic of a three-dimensional model; acquire a material characteristic of a material in a designated region of the target entity where the shape characteristic of the target entity matches with the predetermined shape characteristic; and determine an extent to which the acquired material characteristic matches a predetermined material characteristic based upon a magnitude of differences between the acquired material characteristic and the predetermined material characteristic. The predetermined material characteristic is correlated with the designated region of the three-dimensional model The apparatus determines that the target entity is one of a genuine copy and a pirated copy based on the determined extent to which the acquired material characteristic of the target entity matches the predetermined material characteristic.
