Further description with reference to the accompanying drawings:
because the random dot matrix is visible and invisible under the natural light state or the combination of the two, for example, invisible anti-counterfeiting codes are sprayed and scanned in invisible anti-counterfeiting codes sprayed and printed by an Auxi ink-jet printer, but the invisible anti-counterfeiting codes can be scanned after being irradiated by UV light, so that original collected information and verification collected information are scanned or shot ticket anti-counterfeiting seal images visible under the natural light state, and invisible ticket anti-counterfeiting seal images can be converted into visible ticket anti-counterfeiting seal images under the irradiation of a special light source, the generated random dot matrix comprises but is not limited to position and shape, the randomness and the uniqueness of the seal are ensured, the anti-counterfeiting effect is realized, and the anti-counterfeiting performance is improved;
for example: referring to fig. 3, an example of a stamp anti-counterfeiting machine stamp ink-jet example, the ticket anti-counterfeiting stamp image includes but is not limited to a round stamp, an oval stamp, a triangular stamp, and a rectangular stamp, the ticket anti-counterfeiting stamp image includes but is not limited to one or more combined figures of shapes, patterns, characters, and numbers, and the random dot matrix includes but is not limited to ink-jet positions and shapes;
referring to fig. 4, the example diagram of the anti-counterfeit seal of the ticket to be authenticated shows that when the number in the corresponding modified counterfeit (a 1) is changed to (d 1), the corresponding original anti-counterfeit seal image cannot be identified in the stored original anti-counterfeit seal image, and the identification fails to be compared and is authenticated as false, and similarly, the numbers (e 1), (d 2), (e 2), (d 3), (e 3), (d 4) and (e 4) are authenticated as false;
when the corresponding (a 1) is identified in the stored original anti-counterfeiting seal image according to the (f 1), the random ink-jet dot matrix in the (f 1) and the random ink-jet dot matrix in the (a 1) are identified and compared to be false, and similarly, the random ink-jet dot matrix in the (f 2), the random ink-jet dot matrix in the (f 3) and the random ink-jet dot matrix in the (a 1) are identified to be false, namely if the seal is simply modified in a manual ps mode, the authenticity can be rapidly identified and judged;
the identification and comparison process of the image processing and comparison module can be as follows: the method comprises but is not limited to A \ D, binaryzation, image preprocessing of image smoothing, transformation, enhancement, restoration and filtering, extraction and selection of the characteristics of the preprocessed image, classification and comparison of the image characteristics of an identification object according to a classifier of the image characteristics, and obtaining a comparison result above a similarity judgment standard so as to reduce the error rate of processing and comparison;
referring to fig. 2, when the stamp anti-counterfeiting platform collapses and the image processing comparison module cannot process and compare completely consistent associated original ticket anti-counterfeiting stamp images and ticket anti-counterfeiting stamp images to be authenticated, the information display module of the stamp anti-counterfeiting platform displays the comparison information formed by the original ticket anti-counterfeiting stamp images and ticket anti-counterfeiting stamp image information to be authenticated, which are identified by the image processing comparison module and stored in similar association, on the stamp anti-counterfeiting platform and feeds the comparison information back to the user side for manual verification and comparison through naked eyes, so that the user can timely obtain the comparison information and manually assist verification under the condition that the platform collapses and cannot be intelligently identified;
the seal anti-counterfeiting platform stores the anti-counterfeiting seal identification result and the anti-counterfeiting seal image information of the ticket to be identified in a storage file, so that a user can log in a user side, the seal anti-counterfeiting platform calls the storage file to inquire and browse historical identification data, and the user identifies the authenticity of the ticket through the anti-counterfeiting seal identification result;
therefore, the unique and double anti-counterfeiting ticket anti-counterfeiting seal is formed by the seal graph and the visible or invisible random ink-jet dot matrix, the anti-counterfeiting performance is obviously improved, and the cloud tracing is stored; any user carries out rapid identification comparison on the ticket anti-counterfeiting seal information from two layers of the ticket anti-counterfeiting seal image and the ink-jet random dot matrix according to intelligent identification to obtain an anti-counterfeiting seal identification result, and the user side obtains the anti-counterfeiting seal identification result or uses the original ticket anti-counterfeiting seal image and the ticket anti-counterfeiting seal image to be identified for manual verification, so as to identify the authenticity of the ticket and store the ticket anti-counterfeiting seal image and the ticket anti-counterfeiting seal image in a storage file to be capable of following identification history information; the method avoids the limitation of factors such as an identification mechanism, a field, cost, time and the like, obviously improves the identification efficiency and the identification reliability of the anti-counterfeiting seal of the ticket, effectively prevents the occurrence of conditions such as cloning and counterfeiting of the seal on the ticket and the like, and provides guarantee for the practical application supervision of the anti-counterfeiting seal of the ticket and the anti-counterfeiting and authenticity of the ticket in the circulation process.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention.
