[0044] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings of the specification.
[0045] Such as figure 1 As shown, the present invention designs a product digital watermark anti-counterfeiting and anti-smuggling system, including product packaging with digital watermark added, and is characterized in that it also includes a client for obtaining product packaging images, and a system for communicating with the client. Server side; where the client side obtains the product packaging image and uploads it to the server side. The server side performs digital watermark verification according to the received product packaging image, and at the same time restores the product information value data, obtains the product information according to the data, and finally the authenticity result Send product information and product information to the client to realize product anti-counterfeiting and anti-counterfeiting; this system stores product information on the server side, collects the watermark area image of the product package with digital watermark by designing the client side, and uploads it to the server side for retrieval and verification , Through the verification methods of the collection object, the client and the server, the product packaging can be effectively prevented from being illegally copied, effectively avoiding the problem of product channeling, and realizing the anti-counterfeiting of the product, ensuring the authenticity of the product, and protecting the product Market circulation order.
[0046] Correspondingly, such as figure 1 with figure 2 As shown, the present invention designs an application method for designing a product digital watermark anti-counterfeiting and anti-smuggling system based on the present invention, which includes a digital watermark adding method, and the actual application includes the following steps:
[0047] Step A01. The product information of the product to be added with a digital watermark is converted into the product information value data of the product according to the preset product information value correspondence relationship, and the product index number is added, and then stored on the server side, where the to be added The product information of the watermarked product includes the product name, manufacturer, product packaging and printing manufacturer, product batch and sales area. Here, there is no specific restriction on the corresponding relationship between the preset product information and the designer can follow their own requirements, as long as the product information is met One-to-one correspondence with the numerical data of the product information is sufficient;
[0048] Step A02. According to the preset data calculation rules, the product information value data of the product is converted into a data string, which is used as the watermark adding location data of the product, each watermark adding location data and the product information of each product The numerical data corresponds to each other and is stored on the server; where the watermark adding location data represents the digital watermark adding location on the product packaging electronic map. Here, there is no specific restriction on the preset data calculation rules, and the designer can follow his own requirements , As long as it meets the one-to-one correspondence between the product information numerical data and the watermark adding location data;
[0049] Step A03. Add the digital watermark according to the watermark adding location data of the product, the numerical data corresponding to the preset product watermark, and the preset image attribute update rules, specifically according to the numerical data corresponding to the preset product watermark and the watermark adding location data. The image attribute data is updated on the digital watermark adding position of the product packaging electronic map to realize the addition of the semi-fragile digital watermark on the product packaging electronic map. The preset product watermark corresponds to the product category one to one, and is stored on the server side, The numerical data corresponding to the preset product watermark is obtained by the preset product watermark according to the preset computer number system conversion rule; the numerical data corresponding to the preset product watermark represents the image on the digital watermark adding position on the product packaging electronic map Attribute data update corresponding rule number; the image attribute data update includes image gray value update data, image brightness value update data, or multiple relative data on the product packaging electronic drawing that specify the gray value of the image at the position of the digital watermark Or the relative data of the image brightness value. Here, there is no specific restriction on the preset computer number system conversion rules. The designer can do it according to his own requirements, such as binary, ternary, etc., if it is binary, including the values ​​"0" and " 1", need to design two image attribute data update methods corresponding to it; if it is ternary, including the values ​​"0", "1" and "2", need to design three image attribute data update methods corresponding to it ; At the same time, it is necessary to satisfy that the numerical data corresponding to the preset product watermark corresponds to the preset product watermark one-to-one, and the preset product watermark corresponds to the product category one-to-one;
[0050] The preset image attribute update rules can be set according to the actual situation of adding semi-fragile digital watermarks to ensure that the digital watermarks of the update rules are semi-fragile. Among them, according to the watermark adding position data, determine the digital watermark adding position on the product packaging electronic map, Since the numerical data corresponding to the preset product watermark represents the rule number corresponding to the image attribute data update at the digital watermark addition position on the product packaging electronic map, the image attribute data update includes image gray value update data and image brightness value update data Or the product packaging electronic drawing specifies multiple relative data of the image gray value or image brightness value at the position of the digital watermark. In practical applications, if the image attribute data update is the image gray value update data, preset Image attribute update rules include setting the image gray value between 0-127, corresponding to image attribute update rule 1, and setting image gray value between 128-255, corresponding to image attribute update rule 2, such as the numerical data corresponding to the preset product watermark Corresponding to a string of binary numbers, such as "1010", first determine the first digital watermark adding position on the product packaging electronic map according to the watermark adding position data, and the image attribute data corresponding to this position is updated to the value data corresponding to the preset product watermark The first number "1" in "1010", if according to the preset image attribute update rule, the "1" in the numerical data corresponding to the preset product watermark is set to correspond to the image attribute update rule in the preset image attribute update rule 2. Set the image gray value at 128-255; the "0" in the numerical data corresponding to the preset product watermark is set to correspond to the image attribute update rule in the preset image attribute update rule 1. Set the image gray value at 0-127; the image attribute data corresponding to the first digital watermark addition position on the electronic product packaging map is updated to the image gray value of 128-255; and so on, the images corresponding to the other digital watermark addition positions on the product packaging electronic map Attribute data update method;
[0051] Step A04. According to the electronic drawing of the product packaging with the semi-fragile digital watermark added, the product packaging with the function of anti-counterfeiting and counterfeiting is obtained through printing.
[0052] In the present invention, such as figure 1 with figure 2 As shown, the digital watermark verification method as opposed to the digital watermark adding method includes the following steps:
[0053] Step B01. Obtain the product packaging image of the product to be inspected through the client, correct the product packaging image, and upload it to the server;
[0054] Step B02. The server-side traverses each piece of product information value data belonging to the same product category as the product to be inspected, and obtains each piece of product information value data corresponding to each piece of product information value data according to the preset data calculation rules described in step A02. Add location data to each watermark;
[0055] Step B03. For the received product packaging image, the server side extracts the image corresponding to the digital watermark adding location of each watermark adding location data on the product packaging image according to the preset image attribute update rules and each piece of watermark adding location data. Attribute data, for example, in the process of adding digital watermarking, image attribute data update uses image gray value update data. The preset image attribute update rules include setting the image gray value between 0-127 and corresponding image attribute update rule 1. The image gray value is 128-255, corresponding to image attribute update rule 2, then the server side extracts the image gray value of each watermark adding position data corresponding to the digital watermark adding position on the product packaging image, if the corresponding If the image gray value is 0-127, the extracted watermark value data is "0", if the corresponding image gray value is 128-255, then the extracted watermark value data is "1", according to the above corresponding rules, respectively Each piece of watermark adding position data obtains the image gray value of each digital watermark adding position on the product packaging image in turn, and obtains the corresponding value of the image gray value according to the above corresponding rules, and forms the corresponding watermark value data of the product to be inspected , That is, each piece of watermark value data of the product to be inspected corresponding to each piece of watermark adding position data is obtained;
[0056] Step B04. The server side traverses each piece of product watermark value data to be inspected, and obtains the difference between each piece of product watermark value data to be inspected and the preset product watermark corresponding value data of the product category of the product to be inspected on the server side. Correlation value, judge whether the maximum correlation value is greater than the preset correlation threshold, if yes, obtain the watermark value data of the product to be inspected corresponding to the maximum correlation value, and obtain the product information value data corresponding to the watermark value data of the product to be inspected ; Otherwise, the product packaging image is judged to be false;
[0057] Step B05. The server obtains the product information of the product to be inspected according to the product information numerical data, and sends the product information and the authenticity detection result back to the client, and the user can obtain the product information of the product to be inspected , Carry out inspections and complete the authenticity inspection for the products to be inspected.
[0058] The above image attribute data update is the image gray value update data, and the image attribute data can also be updated to the image brightness value update data. Compared with the numerical data corresponding to the binary preset product watermark, 0 means that the brightness value is reduced by 20 %, 1 means to increase the brightness value by 20%; this also applies to other image attributes.
[0059] In the present invention, there are two types of areas on the product packaging electronic map where the digital watermark adding location is located. The first is that the digital watermark adding location on the product packaging electronic map is located in a preset area on the product packaging electronic map ; The second is that the digital watermark on the product packaging electronic map is located in any area on the product packaging electronic map, the result of these two cases is that for the digital watermark verification method, the customer Whether the terminal can accurately obtain the product packaging image in the area where the digital watermark is added, this is a problem involved in the present invention: clear watermark and dark watermark. The clear watermark clearly knows the area where the digital watermark is added on the product package, namely The area is preset; the dark watermark is the area where the digital watermark is not known on the product package, that is, the area is arbitrary; for these two situations, the present invention specifically designs the following solutions.
[0060] When the digital watermark adding position is located in any area on the product packaging electronic map, the step B01 includes the following content:
[0061] Arbitrarily use one of the following methods a and b to determine the area where the digital watermark is added is located on the product package, and then obtain the image of the area on the product package of the product to be inspected through the client as the product package Image, and correct the product packaging image, and then upload it to the server;
[0062] Method a. After adding a digital watermark to the product to be added, select four image feature points (such as frame, center, corner, and some text in the area where the digital watermark is added on the electronic map of the product package). Part, etc.) as the watermark positioning point, and stored in the server, the watermark positioning point corresponds to the product category one to one; in the watermark verification method, first obtain all the images of the product packaging of the product to be inspected through the client, and then Obtain the watermark anchor point corresponding to the product category of the product to be inspected from the server, match the watermark anchor point with all images of the product packaging to determine the area where the watermark anchor point is located, and then obtain the product to be inspected through the client The image of this area on the package is used as the product packaging image, and the product packaging image is corrected, and then uploaded to the server;
[0063] Method b. After adding a digital watermark to the product to be added, select the four corners of the watermark area as the watermark positioning point in the area where the digital watermark is added on the electronic map of the product packaging, and the watermark positioning point and its vicinity A robust digital watermark is added to the area and stored in the server. The robust digital watermark corresponds to the product category one-to-one; in the watermark verification method, first obtain all the images of the product packaging of the product to be inspected through the client, and then Obtain the robust digital watermark corresponding to the product category of the product to be inspected from the server, traverse all the images of the product package, obtain the correlation of the robust digital watermark in all the images of the product package, and compare the correlation of each point The performance values ​​are arranged from large to small, starting from the point corresponding to the maximum correlation value, four points are selected as the watermark positioning points, and then the image of the area where the four watermark positioning points on the product package to be inspected is obtained through the client , As the product packaging image, correct the product packaging image, and upload it to the server;
[0064] Regarding that the digital watermark adding position is located in a preset area on the electronic drawing of the product packaging, the step B01 includes the following content:
[0065] Step B01. Obtain the image of the pre-set area of ​​the digital watermark adding position on the product packaging of the product to be inspected through the client as a product packaging image, correct the product packaging image, and upload it to the server.
[0066] In summary, the application method of the product digital watermark anti-counterfeiting and anti-smuggling system designed based on the present invention designed by the present invention is based on the structure of the collection object, the client and the server, and a brand-new digital watermarking method is designed. Image information is defined to realize product packaging with anti-counterfeiting and anti-smuggling functions, and combined with product information stored on the server side to realize network verification of product information, avoiding the loopholes of traditional digital watermark verification, and making product packaging more anti-counterfeiting and anti-counterfeiting The effect of fleeing goods, the whole process is interlinked, and the logic is clear, which effectively guarantees the quality of the product and the market circulation of the product; among them, the product information stored on the server can include the product name, manufacturer, product packaging and printing manufacturer , Product batches and sales areas, etc., based on the verification structure of the collection object, client, and server, remotely realize the verification of multiple information of the product, avoiding the falsification and counterfeiting of the product to the greatest extent; and the traditional watermark The pattern is converted into corresponding numerical data according to the preset computer number system conversion rules, and then applied according to the digital watermark adding method described in the technical solution, which realizes remote product information verification and makes the application of the digital watermark more secure , To further improve the security of product anti-counterfeiting and anti-counterfeiting; for the addition of digital watermarks on the electronic drawings of product packaging, semi-fragile digital watermarks are added, because semi-fragile digital watermarks will be severely damaged after illegal copying, which directly affects the product packaging The correct extraction of information, therefore, the design of semi-fragile digital watermarks can effectively prevent copying and textiles for product packaging; not only that, the designed digital watermark verification method and the digital watermark adding method are asymmetrical, which makes illegal cracking of forged product information The difficulty is greatly increased, which effectively guarantees the quality of the product and the market circulation of the product; and in the digital watermark verification method, in the analysis process of the correlation value, the digital watermark verification of the entire system is effectively improved by narrowing the traversal range The work efficiency of the system reduces the workload of the system; not only that, for the area where the digital watermark is added on the product packaging electronic map, the design can be specified in advance on the product packaging electronic map, or located at any position on the product packaging electronic map , And designed different methods for the client to obtain the product packaging image of the product to be inspected for the two situations, which meets the different needs of the market, and more effectively improves the security of the product’s anti-counterfeiting and anti-sweeping products, and maximizes the guarantee To ensure the authenticity of the product, and to ensure the stability of product market circulation.
