This invention discloses a serially arranged, disordered anti-counterfeiting hidden code system, relating to the field of anti-counterfeiting hidden code technology. The hidden code system includes a generation system and an identification system. The generation system includes an identification code, which is generated by a host computer and contains product information. The identification system reads the entered product information. The identification code and product information contained in the generation system are converted into a dot matrix image code using a host computer's encoding and decoding algorithm. The identification system includes code recognition software. This serially arranged, disordered anti-counterfeiting hidden code system mixes a dot matrix image code containing product information with a hidden code, concatenates them, and then scrambles them before storing them in a code pattern library. Combined with a conventional QR code, it forms an anti-counterfeiting hidden code. The hidden code dots, processed with invisible ink, cannot be counterfeited through printing and can only be read and recognized by code readers in stores and manufacturers, thus achieving the anti-counterfeiting effect.
