Description

Technical Field

[0001] The present invention relates to the technical field of anti-counterfeiting and tracing technology, and in particular to an anti-counterfeiting and tracing method based on a secret code. Background Art

[0002] Anti-counterfeiting traceability is the use of modern information technology to verify product authenticity and trace product raw materials, production, storage, and logistics information. It has been widely used in a variety of products such as electronic products, skin care products, and medicines. How to completely eliminate counterfeiting and shoddy products from the root? Simply verifying product manufacturer information is far from meeting market demand. Being able to monitor products while preventing counterfeiting has become the main trend of anti-counterfeiting development in recent years. The anti-counterfeiting traceability system has thus developed into an independent branch of the anti-counterfeiting system and continues to grow.

[0003] The existing anti-counterfeiting and traceability technology sprays the anti-counterfeiting code on the product through an inkjet printer. The anti-counterfeiting code is easy to be tampered with or destroyed, which seriously affects the reliability of anti-counterfeiting and traceability. Summary of the invention

[0008] The anti-counterfeiting traceability information includes batch information, product number information, expiration date information, origin information, inspection information, warehousing information, logistics information and anti-counterfeiting serial verification code;

[0009] The anti-counterfeiting and traceability information code includes a one-dimensional code and a two-dimensional code;

[0010] The anti-counterfeiting and traceability information code matches a unique product;

[0011] Step 2: transcoding, identifying the anti-counterfeiting traceability code generated in step 1, decoding it, obtaining the anti-counterfeiting traceability information, and then converting the decoded anti-counterfeiting traceability information into an invisible secret code;

[0012] The invisible secret code is matched with a unique anti-counterfeiting traceability information code;

[0013] The invisible secret code includes a first invisible secret code and a second invisible secret code;

[0014] The first invisible secret code is encoded as a string of 6 to 13 digits;

[0015] The second invisible secret code is encoded as a string of 13 to 30 digits;

[0016] Step 3: Invisible code spraying: use the inkjet printer to spray the invisible code on the surface of the product;

[0017] The inkjet printer uses invisible inkjet material as inkjet ink;

[0018] The coding ink comprises a first coding ink and a second coding ink;

[0019] The invisible inkjet material is CaWO4:Eu 3+ 、CaWO4:Sm 3+ 、Y2O2S:Sm 3+ and Y2O2S:Eu 3+ Any two of the following;

[0020] The first invisible secret code is sprayed with a first spray ink;

[0021] The second invisible secret code is sprayed with a second spray ink;

[0022] Step 4: Code reading: the user uses an invisible code reading device to read the invisible code on the surface of the product;

[0023] The invisible code reading device is a near-infrared imaging device;

[0024] The near-infrared imaging device comprises a first light source, a second light source, a near-infrared detector, a signal processor and a display;

[0025] The near infrared detector can detect near infrared light;

[0026] Step 5: Anti-counterfeiting and tracing. After the user enters the anti-counterfeiting and tracing system and completes the registration of the user account, he / she completely enters the second invisible secret code. The anti-counterfeiting and tracing system outputs the unique corresponding anti-counterfeiting and tracing information code, which is decoded to obtain the anti-counterfeiting and tracing information.

[0027] The user verifies the authenticity of the product by comparing the anti-counterfeiting sequence verification code in the anti-counterfeiting traceability information with the first invisible secret code.

[0028] Furthermore, the first invisible secret code and the anti-counterfeiting sequence verification code are the same character string.

[0029] Furthermore, the second invisible secret code includes a batch information code, a product number information code, an expiration date information code, an origin information code, an inspection information code, a warehousing information code, a logistics information code and a conversion information code.

[0030] Furthermore, the batch information code, article number information code, expiration date information code, origin information code, inspection information code, warehousing information code and logistics information code are obtained by converting the batch information, article number information, expiration date information, origin information, inspection information, warehousing information and logistics information respectively.

[0031] Furthermore, the conversion information code is obtained by mathematically converting the batch information code, article number information code, expiration date information code, origin information code, inspection information code, warehousing information code, and logistics information code.

[0032] Furthermore, the anti-counterfeiting sequence verification code is randomly generated.

[0033] Furthermore, the registration of the user account includes user information input and user activation.

[0034] Furthermore, the user activation process includes:

[0035] The user enters a first invisible secret code;

[0036] The user enters a second invisible secret code;

[0037] The anti-counterfeiting traceability system receives the first invisible secret code and the second invisible secret code input by the user, decodes them to obtain the anti-counterfeiting serial verification code of the corresponding product, and determines whether the user has successfully registered by comparing the first invisible secret code input by the user with the anti-counterfeiting serial verification code.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The present invention uses CaWO4:Eu 3+ 、CaWO4:Sm 3+ 、Y2O2S:Sm 3+ and Y2O2S:Eu 3+ As inkjet ink, it makes the anti-counterfeiting traceability code invisible, effectively preventing the tampering and destruction of the anti-counterfeiting traceability code, and improving the effectiveness and reliability of anti-counterfeiting traceability;

[0040] 2. The present invention adopts two kinds of coding inks to respectively code the first invisible code and the second invisible code, and the matching near-infrared imaging device is provided with a first light source and a second light source, which divides the anti-counterfeiting and traceability code into two independent systems, so that ordinary infrared imaging devices cannot recognize the anti-counterfeiting and traceability code of the present invention, thereby improving the reliability and security of the anti-counterfeiting and traceability.
