An information identification apparatus includes a processor and a storage device. The storage device stores computer programmed instructions which when activated by the processor cause the processor to operate as a specially programmed processor. The processor obtains image data assumed to be embedded with supplemental information, extracts a portion of the image data to obtain target pattern data from the portion of the image data, obtains reference information, compares the target pattern data with the reference information to generate a comparison result, and determines whether the supplemental information embedded in the image data is identifiable using the reference information based on the comparison result. |
