Description

A new counterfeit detection device

technical field

The invention belongs to the technical field of information encryption and anti-counterfeiting, and relates to a new-type counterfeit checking device (also known as an intelligent counterfeiting checking pen) and a counterfeiting checking method thereof.

Background technique

Commodity anti-counterfeiting has been a problem for a long time. As far as the anti-counterfeiting measures adopted by various commodities are concerned, there are many inconveniences such as easy imitation, high cost, cumbersome counterfeiting process, and unreliable traceability of source manufacturers. . Now there is a new type of electronic IC card with digital encryption, which uses a PVC board as the substrate, and one side of the substrate is a smooth cardboard surface, which can be printed with the production identification code of the company that uses the IC card, or it can be a specific pattern or light. The other side of the substrate is provided with non-polar double output electrodes or polarized ring-type output electrodes. The double contact electrodes are metal-coated electrodes, which are used for external power supply of integrated circuits in IC cards and IC chips and The external equipment carries out digital communication, and the communication method adopts the standard one-wire communication method or the two-wire communication method; the globally unique code IC chip with digital encryption is bound on the double contact electrodes, and then fixed with epoxy resin. In the IC card chip, the information code is written into the IC card chip at one time, and the information code itself is encrypted with 256-1024 digits, and the chip information is permanently stored and cannot be changed. The IC card chip is one-time use, non-repeatable, non-replicable. The profile of the IC card can be a variety of shapes such as regular polygons and circles, and can also be a closed figure composed of irregular polygons and irregular arcs; its plane area can be 0.25 square centimeters to 4 square centimeters, and the thickness Generally between 0.2 and 5.0 mm; each IC card will be covered with a plastic film on the electrodes of the IC card after the code is written and verified. When it is counterfeit, the film is pierced by consumers to be connected with the contact electrodes of the inspection equipment for counterfeiting. Non-polar dual output electrodes include symmetrical double contact electrodes and asymmetric double contact electrodes. The symmetrical double contact electrodes can be circular symmetrical electrodes, semicircular symmetrical electrodes, square symmetrical electrodes, polygonal symmetrical electrodes, oval symmetrical electrodes, etc. Asymmetric double-contact electrodes can be circular asymmetric electrodes, semicircular asymmetric electrodes, square asymmetric electrodes, polygonal asymmetric electrodes, elliptical asymmetric electrodes, etc., and the polarized ring-type output electrodes can be circular Shaped ring ring-type asymmetric electrode, semicircular ring-type asymmetric electrode, square ring-type asymmetric electrode, polygonal ring-type asymmetric electrode, oval ring-type asymmetric electrode, etc. Regardless of the two-electrode method, it is enough to facilitate the two-electrode contact of the readout device connected to it.

The counterfeit checking device of the present invention is developed aiming at the above-mentioned new type electronic IC card with digital encryption. When in use, the user only needs to touch the pair of contact poles at the end of the smart counterfeit checking pen to the pair of electrodes on the anti-counterfeit IC card, and then the user can obtain the information through the computer connected to the counterfeit checking device, the wide area network and the manufacturer's database. Information about the inspected counterfeit goods.

Contents of the invention

The invention overcomes the shortcomings of the existing commodity anti-counterfeiting devices and methods, and provides a novel anti-counterfeiting device and method for effectively, quickly and conveniently inquiring about the authenticity of commodities.

Technical scheme of the present invention is as follows:

The counterfeit checking device is composed of a communication interface and an embedded computer microsystem;

Communication interface: there are two, one communication port is a USB physical interface circuit and a USB sub-interface plug, which is used for connecting the counterfeit checking device with a computer. The other communication port is a standard one-wire communication mode or a two-wire communication mode communication interface, which is used to supply power to the checked anti-counterfeit IC card and read out the information in the card. The two-wire communication method does not need to consider the polarity of the IC card output electrodes when communicating with the IC card, while the standard one-wire communication method needs to consider the electrode polarity.

Embedded computer microsystem: The embedded computer microsystem communicates with the anti-counterfeit IC card to read out the anti-counterfeit ID code in the anti-counterfeit IC card; it is used to store the globally unique ID code and provide it to the connected computer for online authentication; The ID code is composed of 256-1024 binary digits after multiple digital encryption.

When in use, the counterfeit checking device is connected to a computer, and then a special institution authorizes it on the Internet. The anti-counterfeiting information of the relevant goods contained in the IC card can be read out by the smart counterfeit checking pen and can be displayed on the smart counterfeiting checking pen in the form of a webpage in the form of network communication through the computer connected to it. connected computer.

The beneficial effects of the present invention are:

1. Low cost;

2. Advanced technology: integrated with digital encryption, wide area network, IC card and database technology;

3. It is extremely difficult to imitate: because the ID code in the counterfeit checking device (also known as: smart counterfeit checking pen) is digitally encrypted, it prevents counterfeiters from understanding the law of the ID code of the counterfeiting checking device (also called: smart counterfeiting checking pen) , so it is extremely difficult for counterfeiters to counterfeit and fake (and create a fake website);

4. Simple counterfeit checking: connect the counterfeit checking device to a PC, laptop or tablet computer, and only need to touch the readout electrode point at the end with the electrode of the anti-counterfeit IC card, and you can immediately access the queried product On the dedicated website (the web page of the query website pops up automatically on the display screen), the relevant information of the product can be obtained from the displayed web page, such as the time of delivery, logistics channel, time of the first query, and the number of queries for this query.

Detailed ways

Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

Embodiment 1: Taking infant milk powder as an example

When the consumer buys the can of milk powder and needs to check for counterfeit, he can ask the merchant for counterfeit checking, and the salesman can tear off the protective plastic film on the electrode surface of the anti-counterfeit IC card in front of the consumer, and then use the counterfeit checking device (also known as: intelligent counterfeit checking pen) electrode, contact with the electrode of the IC card for more than 1 second, at this time, automatically on the PC screen connected with the counterfeit checking device (also known as: intelligent counterfeit checking pen) A milk powder manufacturer's webpage pops up, which will display the date of manufacture of the can of milk powder, logistics channels, number of inquiries, product expiration date and other issues that buyers care about. Consumers who buy milk powder can also purchase a counterfeit checking device (also known as: intelligent counterfeit checking pen) from the milk powder manufacturer. Of course, the production cost of the counterfeit checking device (also known as: intelligent counterfeit checking pen) is relatively low, and the milk powder manufacturer can provide a counterfeit checking device (also known as: smart counterfeit pen) for free to those who buy more milk powder, such as those who buy a box of milk powder at a time. counterfeit checking pen), and then consumers can check counterfeit on their own computers.

Example 2: Take the use of high-end wine packaging as an example

When a user buys a bottle of famous wine and needs to check for counterfeit, the operation process is the same as that of milk powder.
