The foregoing is a summary of the present invention, and in order to provide a clear understanding of the technical means of the present invention and to be implemented in accordance with the present specification, the following is a detailed description of the preferred embodiments of the present invention.
Detailed Description
The following examples are given to further illustrate the embodiments of the present invention. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The anti-counterfeiting tracing method based on the multi-spectrum wavelength is characterized in that: the fingerprint printed by ink with different absorption spectra can be randomly sprayed and provided with variable data read-write frequency label codes. Therefore, the fingerprint and the radio frequency tag are mutually associated, and encryption is carried out by adopting a server or cloud computing so as to associate the fingerprint and the radio frequency tag. Thus, the difficulty of copying the tag data can be increased.
During implementation, fingerprints are produced on the surface of an article, and a server or a cloud platform generates radio frequency tag codes. And then, each tracing point reads the clear code of the radio frequency tag through monitoring equipment, and modifies and reports the position and the time stamp of the article. And then, the terminal user reads the radio frequency tag clear code through reading equipment, reports the radio frequency tag clear code to a server or a cloud platform, obtains a fingerprint sampling inspection position sequence and verifies the authenticity. In addition, in order to reduce the workload of repeated checking, the invention can trace the identity and the file of the article without a radio frequency tag after completely comparing the fingerprints.
In a preferred embodiment of the present invention, the fingerprint forming process is to apply N inks with different absorption spectrum wavelengths to each object to be encoded, and randomly mix and spray-print the inks on a fixed area of the object surface, such as a blank of a package trademark, to form ink dots. And the absorption spectrum frequency and the position data of each ink dot are stored as the fingerprint code of the article through a server or a cloud platform. Meanwhile, in consideration of the diversification of printing requirements, in order to meet different encryption requirements, the ink adopted by the invention is color ink. Of course, infrared inks (absorption wavelengths of 720 nm and above) are also possible, as desired for certain applications. Further, ultraviolet ink may be used to calculate the distribution or statistical distribution according to a specific position.
From the practical implementation point of view, it is found through many comparison tests that the specific positions are every 128 × 128 grids, and random points are formed, or two-dimensional codes, or textures, or patterns are formed. Thus, the printing and encryption requirements of most of the printing and encryption can be met, and clear identification can be guaranteed. Meanwhile, for the printing of common trademarks, the adopted statistical distribution is Gaussian distribution with trademarks as the center.
Further, the radio frequency tag used in the present invention is of a type compatible with the NFC reader. Specifically, the radio frequency tag stores an article personalized code, a server or a cloud platform gives the article personalized code a tracing location and a timestamp code through a tracing monitoring point, and the code generates a check bit. Therefore, codes outside the server or the cloud platform are prevented from being generated, and reading is facilitated.
Meanwhile, during actual implementation, the cloud platform generates a unique identity code and a check bit for each article, and the identity code is endowed with the radio frequency tag. And then, the server or the cloud platform associates the item fingerprint code with the identity code. During the period, when the article passes through the tracing monitoring point, the monitoring read-write equipment with the unique identity mark exchanges the encrypted data file with the server or the cloud platform through the network. The exchange process comprises reading, recording and modifying the radio frequency label tracing positioning and the time stamp coding.
And then, when the user inquires the authenticity, reading the clear code of the radio frequency tag through the reading equipment. Then, a fingerprint ink dot detection position sequence is randomly generated through a server or a cloud platform. Thus, the reliability of the authenticity of the article is detected by the reading device camera. Moreover, the identification code can be confirmed and the file can be traced by comparing the associated data after the fingerprint is scanned. Furthermore, in view of implementation convenience, the adopted reading device is a smart phone with a camera. Since smart phones are already popular, the implementation of the present invention can be satisfied only by matching corresponding apps.
The working principle of the invention is as follows:
two spectral wavelengths are used in the fingerprint part: infrared invisible ink with spectral wavelength of 720 nm, ultraviolet fluorescent ink with spectral wavelength of 200 nm. The invisible infrared ink is sprayed and printed with a 4mmx4mm two-dimensional code on the surface of the packaging material, and the code confirms the division number of the branch company production department of the product, and the coordinates are randomly distributed.
Therefore, it is very difficult to find the tiny infrared invisible two-dimensional code on the huge surface of each packing box, and the damage difficulty of the goods-shakeup person is greatly improved. The ultraviolet fluorescent ink is sprayed and printed in the area of the trademark bar code according to a pseudorandom sequence with a plain serial number as a seed number. And the serial number and the ultraviolet invisible ink point are stored on the cloud platform.
In order to improve the safety, a radio frequency tag chip is arranged in the packaging box, the frequency is 13.56MHz, and the packaging box is compatible with the NFC of a mobile phone. When the packaging box is packaged, the serial number, the starting position and the time stamp and a check code (network communication needs to be encrypted) generated by the data through the cloud platform are written on line.
Therefore, when passing through a tracing point of logistics, the tracing equipment reads and reports the serial number of the cloud platform, generates a new position and a new time stamp at the same time, and acquires the check bit through the cloud platform. And new data is written into the radio frequency tag through the tracing device.
During the implementation period, the terminal user reads the clear code of the radio frequency tag by one to confirm whether the damage phenomenon exists. If the goods are mixed, the goods mixer can be found out by scanning the infrared invisible two-dimensional code to analyze the area code of the production department. If the plain code of the radio frequency label is read smoothly, the cloud platform can generate a random sampling position sequence and a random sampling result sequence, and a terminal user can detect the sampling point in the trademark bar code area by using an ultraviolet lamp and a mobile phone. The credibility of the authenticity of the article can be known through the codes of the sampling points. The detection is completed by automatically contacting the cloud platform through the mobile phone App and the machine vision algorithm.
In other words, the invention can realize that ink drops with different absorption spectra are sprayed and printed on the surface of an object according to a mathematical model (size, shape, position, density, distribution and the like) to form a fingerprint. The invisible ink is sprayed on the surface of legal graphics (such as trademarks), so that the effect of preventing fingerprint damage without changing the printing and typesetting of objects is achieved. Meanwhile, the radio frequency meter identity identification clear code of the check bit can be generated. The fingerprint and the plain code are generated respectively and are associated through a server or a cloud platform. Scanning the fingerprint can obtain the associated plain code and the tracing archive. After the plain code is read, the verification point sequence is randomly extracted from the massive fingerprint points through a server or a cloud platform to calculate the authenticity credibility.
The above description shows that the invention has the following advantages:
1. the fingerprint and the radio frequency tag are used in a correlation mode, so that variable information can be conveniently read and written while the code is difficult to imitate.
2. The complexity of the fingerprint makes it difficult to achieve the purpose of cross-delivery by destroying the package, and the implementation safety is improved.
3. The terminal client can conveniently detect the truth of data through the mobile phone, and the tracking and tracing are convenient to realize.
4. Through the low-cost establishment of the tracing system formed by the invention, the radio frequency detection optical detection equipment and the cloud platform are completely independent and mature technical modules, and the existing production line does not need to be transformed in a large scale.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
