Internet-based multi-level two-dimensional code anti-counterfeiting method, device and system

An Internet-based multi-level two-dimensional code anti-counterfeiting device, comprising:

• a two-dimensional code generating unit for generating two-dimensional code groups corresponding to each commodity in a one-to-one manner and uploading to an anti-counterfeiting system, each two-dimensional code group comprising at least one disclosed first two-dimensional code and one undisclosed second two-dimensional code, and the second two-dimensional code being unidirectionally associated with information of the first two-dimensional code;
• a first two-dimensional code information reading unit for reading the first two-dimensional code, uploading information related to production time of the commodity, a place, composition and quality inspection of the commodity to the anti-counterfeiting system in real time through an appointed IP address after reading by a two-dimensional code reading device, and simultaneously activating the second two-dimensional code while reading the first two-dimensional code;
• a second two-dimensional code information reading unit for reading information of the second two-dimensional code, and linking to the anti-counterfeiting system;
• a judging unit for judging whether a commodity is a genuine commodity:
• if so, entering an associated information capturing unit and if not, entering a non-genuine commodity information feedback unit;
• an associated information capturing unit for capturing commodity information and related information of the first two-dimensional code associated with the second two-dimensional code;
• an information downloading unit for downloading the commodity information and the related information of the first two-dimensional code from a server of the anti-counterfeiting system to a client of a user for displaying;
• and
• a non-genuine commodity information feedback unit for sending feedback information that the commodity is not a genuine commodity to the user.
