Problems solved by technology

Since the texture distribution is a kind of pattern, it usually needs to be checked in the form of a specific image with the help of a fax machine or the Internet. If it is described by voice on the phone, it is not only cumbersome, but also extremely inaccurate. In addition, the usual color printers and color copiers also have The pattern effect of this texture marker can be reproduced in large quantities easily and at a very low cost
[0003] The Chinese invention patent with the application number of 96233300.X—electronic aging anti-counterfeiting device for commodities involves an electronic device that is controlled by a clock to change the number every day as an anti-counterfeiting marker. Its disadvantage is that it must have an oscillation that consumes power all the time Circuit, due to the complexity of the circuit, the cost of anti-counterfeiting is high, and the reliability is difficult to guarantee

Embodiment 1

[0018] The concrete steps of embodiment 1 are:

[0019] 1. Set a non-repetitive and non-continuous code for each product, cover the code, and print the inquiry phone number or the website address of the inquiry website;

[0020] 2. Attach the decoder to the product, select a set of input and output corresponding code data of the decoder and store the product code in the computer database at the same time.

[0021] 3. Set the effective number of input and output operations of the decoder when designing and manufacturing the decoder;

[0022] 4. When inquiring, the inquirer scratches or uncovers the product code covering layer, and inputs the product code into the computer database according to the inquiring phone number on the product or the website address of the inquiring website by means of telephone, mobile phone or the Internet, if the code is in the computer database If it does not exist, there is no need to check the code data corresponding to the input and output of th...

Embodiment 2

[0025] Embodiment 2, based on above-mentioned embodiment 1, multiple sets of input-output corresponding code data of the selected decoder are simultaneously stored in the computer database with the same product code, and a group of input-output corresponding code data is checked every time the computer database is inquired, and After querying once, the corresponding code data of this group of input and output will be invalidated automatically.

[0026] Analyzing Embodiment 2, its further feature is that it can satisfy multiple valid queries of the same product.

Embodiment 3

[0027] Embodiment 3, based on above-mentioned embodiment 1, embodiment 2, each product has a coding and a decoder with anti-counterfeiting information, has multiple (for example 100 kinds) decoders by the difference of encryption conversion unit, each The decoder on a product can be any one of many kinds of decoders, and the appearance of each decoder is exactly the same, and the type of encryption conversion unit of the decoder corresponds to the product code irregularly.

[0028] Analyzing this embodiment 4, its characteristic is that even if the counterfeiter has the ability to unpack and dissect the microstructure of the encryption conversion unit integrated circuit and successfully manufactures it, he can never know the corresponding products of different types of decoders when counterfeiting Encoding, so it is still impossible to counterfeit.

[0029] figure 2 The size of the middle decoder is 1.5cm square, and each cost is about 1 yuan for mass production according to...

Abstract

The invention relates to an anti false method and its decoder. Especially it is a method to ensure whether the product is true or false by comparing the coincidence relation of input / output of decoder on the produce with that pre-stored on computer database, through communication mode used by a queried user. The characters of the invention are as follows. (a) Each product has a code and decoder. (b) comparing the outputted code from the decoder with the outputted code obtained from computer database. The invention provides evident effect, easy to use and popularize and reduces computer storage needed.

Description

technical field [0001] The invention relates to an anti-counterfeiting method and a decoder for checking the corresponding relationship between input and output, in particular to an inquirer who inputs product codes to a computer database through communication, and stores the corresponding relationship between input and output of the decoder on the product with a pre-stored Check the input and output correspondence of the product code decoder in the computer database to determine the authenticity of the product. Background technique [0002] At present, the anti-counterfeiting technology of telephone codes is widely used. In practical applications, due to the low feedback query rate, usually less than 1%, counterfeiters use the method of repeating and printing one code to imitate: for example, when the product query rate is 1%, The counterfeiter prints 10 more copies of one code. At this time, even if the consumer buys the fake product, the possibility of being judged as gen...
