Abstract

The method of identifying and verifying the truth of goods with digital dot array includes the following steps: presetting the ID code of known goods in the memory of computer or PAD connected one identifier for identifying digital dot array; identifying the ID code with the identifier; transmitting the ID code from the identifier to the computer or PAD and comparing the ID code the identifier obtains and the ID code in the memory in the computer or PAD; and judging the truth of the goods based on whether the ID code the identifier obtains is the same as the ID code in the memory in the computer or PAD.

Description

technical field [0001] The invention relates to a method for object identification and authenticity authentication by using digital dot matrix. Background technique [0002] At present, one-dimensional barcodes and two-dimensional codes are usually used for item identification and authentication. But this method usually has the disadvantage of affecting the appearance of the item. The present invention is applicable to various fields where barcodes are currently used for authenticity identification and authenticity authentication, and is especially suitable for fields where barcodes are incapable, such as banknotes, securities, stamps, passports and the like. The present invention is applicable to but not limited to such fields. Contents of the invention [0003] Aiming at the shortage of article identification and authenticity authentication using barcode, and considering the fields and occasions where barcode is not applicable, a method of article identification and au...
