The method of identifying ownership.

Background technique

Case 1, in China Patent Application No. 95203425. 5 (application date February 7, 1995), titled "Password Anti-Counterfeit Mark", the code and password (anti-counterfeiting information) of the anti-counterfeit mark printed by the anti-counterfeit information carrier And the cover layer; code and password composition code stored in the computer identification system database that provides the consumer with the verification password service, the consumer can dial the code to the computer identification system database by phone to verify the authenticity of the product, it will identify The original and complicated technical behavior of product authenticity is transformed into the simple behavior of telephone verification coding. It is not easy to forge and easy to identify. The National Electric Code Telephone Anti-Counterfeiting System Project promoted by the China National Defense Industry Association has adopted this patented technology. However, in practice, it has been found that there is a phenomenon of fraudulent recovery of anti-counterfeiting marks and a phenomenon of falsification of one yard and multiple prints. It is also found that there is a phenomenon of illegal copying and coding fraud.

Case 2, in the Chinese patent application number is 200520089735. 2 (application date March 17, 2005), the title is "the mobile phone that can identify the authenticity of the goods", the authenticity recognizer is a mobile phone, and the anti-counterfeiting mark is a general two-dimensional Bar code. The technology is characterized by high recognizability, low concealment, low randomness, and easy to counterfeit with ordinary copiers or other simple methods. In addition, the technical threshold of the scheme is low and it is easy to be impersonated.

Case 3: In the Chinese patent application number 201020646885. X (application date December 8, 2010), the title is “an anti-counterfeit mark”, and the anti-counterfeiting mark is printed with the query code and the anti-counterfeiting. An inquiry phone number and a query URL are also available. Users can log in to the website, enter the search code to query, and check the number, color, position and shape of the matching. This technology is characterized by high randomness and low recognizability. The inconvenience of the technology inevitably leads to a low query rate, leaving a loophole for the fraud of one yard and multiple prints.

Case 4, in China patent application number is 01220331228. 5 (application date July 9, 2012), titled "mobile phone code information comparison check security identification and its identification system", the authenticity recognizer for mobile phones, anti-counterfeiting The logo is multi-layered, with a squeegee layer, an information layer and a hollow holographic layer. In use, it is necessary to scrape off the identified ink-repellent layer and then image the hollowed-out holographic layer. The technology is characterized by high privacy and low recognizability. The weakness of this technology is the destructive change of the anti-counterfeiting label, which leads to the user having to "buy and check first" instead of "checking and buying first".

For the first time, China clearly proposed eight general technical requirements for anti-counterfeiting technology products. The contents are as follows: 1) Identity uniqueness: Anti-counterfeiting technology The uniqueness and non-transferability of product anti-counterfeiting identification features. 2) Stabilization period: Under normal conditions of use, the anti-counterfeiting identification feature of anti-counterfeiting technology products can be kept for the shortest time. 3) Safety period: Under normal conditions of use, the anti-counterfeiting technology product anti-counterfeiting feature is the shortest time to be successfully copied. 4) Anti-counterfeiting strength: Identify the authenticity and the durability and reliability of the counterfeit and counterfeit functions. 5) Adaptability: The anti-counterfeiting feature of anti-counterfeiting technology products can be adapted to the requirements of the target or service object. 6) Recognition performance: The anti-counterfeiting feature of the anti-counterfeiting technology product can be correctly identified by the sense or machine within the required identification time. 7) Environmental requirements for use: The anti-counterfeiting performance of anti-counterfeiting technology products should meet the requirements of the normal use environment of the target materials. 8) Technical security and confidentiality: The technology for designing and manufacturing anti-counterfeiting technology products should be secure and confidential.

For the identification of authenticity, although there are many methods in the world, there are few methods for high anti-counterfeiting and convenient use. The main reasons for this are: 1) The technical threshold is low, the technology is easy to be cracked, and it is easy to be copied in large quantities. 2) Inconvenient to use and unable to identify instantly. Some methods require expert identification, and some methods take days or even weeks. These two reasons often lead to users losing confidence in the actual effect of anti-counterfeiting.

detailed description

The embodiments of the present invention will be further described with reference to the drawings in the accompanying drawings.

In the embodiment of the stealth point code anti-counterfeiting system, the embedded point code in the digitized file, the anti-counterfeit mark interpretation and the tenure management method embodiment, the structure diagram of the invisible point code anti-counterfeiting system is shown in FIG. In Fig. 1, the invisible point code anti-counterfeiting system includes an anti-counterfeiting mark 1, an identification interpreter 2, and a background server 3. Anti-counterfeit mark 1, also known as anti-counterfeit mark, or anti-counterfeit mark, is a kind of material that can be pasted, printed, transferred to the surface of the object or on the label of the object or attached to the object (such as commodity listing, business card and security card). In the present embodiment, the anti-counterfeit mark 1 is used to transmit product information, and the purpose thereof is to convey the title, depiction, composition, effective date, brand information, and the like of the product to the consumer. The identifier reader 2 is configured to obtain the authenticity of the anti-counterfeit identification 1 by acquiring the digitized image of the anti-counterfeit identification 1, and the background server 3 is configured to store the code of the issued anti-counterfeit identification 1 and related commodity identification information, and assist the identification reader 2 in anti-counterfeiting Mark 1 is authenticated.

Specifically, the anti-counterfeiting mark 1 is evidence of an entity, and its function is to transmit the commodity information and at the same time serve as a basis for authenticating the authenticity of the commodity. One of the characteristics of the anti-counterfeiting mark 1 is its uniqueness. The pattern on each anti-counterfeit mark is unique, like a human fingerprint, and no two anti-counterfeit marks have the same pattern. A common method of counterfeiting is to first spoof a genuine product and then make a large number of copies. In this embodiment, since there is only one anti-counterfeit mark 1 for each genuine product, the counterfeiter cannot be copied in a large amount. If you want to create 100 fake logos, you must spoof 100 different true logos. This feature greatly increases the cost of fraud, making counterfeiting behavior more worthwhile in many applications. Another feature of the anti-counterfeiting mark 1 is its convenience. When used, the pre-made anti-counterfeit mark 1 can be attached to the product for consumer identification, and the anti-counterfeit mark 1 can be directly printed on the product, which is advantageous for a large quantity, low unit price and high-speed production line.

In this embodiment, the identifier reader 2 is a mobile phone application. Specifically, the identifier reader 2 is a mobile phone reader (specifically, a mobile phone), and its function is to identify the authenticity of the security identifier 1. In this embodiment, one of the features of the identifier reader 2 is to obtain a digitized image of the anti-counterfeit identifier 1 by using the camera function of the mobile phone, and use the communication function of the mobile phone and the background server 3 to perform online operations to identify the authenticity of the anti-counterfeit identifier 1. A further feature of the identification reader 2 is its generalization and ease of use. Modern people are almost a human hand. The identification of anti-counterfeiting mark 1 does not require professional training and does not require complicated and expensive instruments. Everyone can easily use the mobile phone and instantly identify the authenticity of the goods. When purchasing a product, the user simply scans the anti-counterfeiting mark 1 on the product with a mobile phone, and can immediately identify the authenticity of the product. Another feature of the identifier reader 2 is the ability to identify false identifiers. Even if the fake security identifier is 100% identical to the authentic security identifier, it will be authenticated immediately after the identifier reader 2 is compared with the background server 3. come out. The code of the anti-counterfeit mark 1 of the line and the related product identification information. The current anti-counterfeiting mark 1 has a coded capacity of 26 digits in decimal numbers, so that the large capacity is sufficient to include the coding requirements of each item produced in the present and future years. Another function of the background server 3 is to assist the identification reader 2 in detecting false security features. Generally, the user does not directly access the background server 3, and the user interacts with the background server 3 through the identifier reader 2. If it is found that an anti-counterfeiting mark 1 is unissued, it can be concluded that it is fraudulent. If it is found that two anti-counterfeiting marks are the same, it can be concluded that one of them is counterfeit, or both are counterfeit. When a counterfeit occurs, the backend server 3 can immediately notify the user, the manufacturer, and the relevant government department to check the source of the counterfeit.

2 is a schematic structural view of an anti-counterfeit mark in the embodiment. In FIG. 2, the anti-counterfeiting mark 1 includes an invisible point code, a background image 12, and a carrier 13; wherein, the background image 12 is disposed on the carrier 13, the invisible dot code is embedded in the background image 12, and the anti-counterfeiting mark 1 is Its information link. The invisible dot code includes a plurality of color micro dots 11 which are hard to see by the naked eye, and the plurality of color 11 micro dots are arranged in a set encoding manner and are embedded in the background image 12 after being arranged, and finally the generated image is printed. Projected or otherwise displayed on the carrier 13.

In this embodiment, the color micro-dot 11 in the anti-counterfeit mark 1 is invisible, and the invisible dot code combined by the color micro-dot 11 carries the encoded information of the anti-counterfeit mark 1. The background image 12 of the anti-counterfeiting mark 1 is randomly generated and carries the anti-counterfeit content. In addition, the background image 12 is explicit, carrying only the anti-counterfeit content, and does not carry the encoded information. The carrier 13 of the security feature 1 is phenotype, and the carrier 13 includes a paper medium or a plastic medium or a metal medium or a computer screen or a mobile phone screen. The anti-counterfeiting identifier 1 in this embodiment has two types: a static identifier and a dynamic identifier. The static identification means that the one-time imaging of the anti-counterfeit identification content is permanently unchanged after being imaged on the carrier 13. The imaging methods for static identification include: 1) Printing the anti-counterfeit identification content on the carrier 13 using a printer. 2) The contents of the security mark are engraved on the carrier 13 using various engraving machines. In general, the process of statically labeled imaging is based on the carrier and method of use. The characteristic of static identification is that the content on the carrier is static and unchanged. Dynamic identification mainly refers to imaging the content of the anti-counterfeit logo on the screen of a TV, computer or mobile phone. The feature of dynamic identification is that the content on the carrier is dynamic and will change.

In this embodiment, the coding information includes one-dimensional coding or multi-dimensional coding. Specifically, the coding information in the anti-counterfeit identifier 1 may be one-dimensional or multi-dimensional. To put it simply, one-dimensional coding means that there is only one number in an anti-counterfeiting sign 1, and there can only be one link hotspot to complete a task. Multi-dimensional coding refers to an area with a multi-dimensional space in an anti-counterfeiting mark. In this area, there may be multiple link hotspots, that is, there may be multiple numbers in one anti-counterfeit mark, or multiple link hotspots. Complete multiple tasks. In this embodiment, the code of the anti-counterfeit mark 1 is multi-dimensional code.

A general bar code or two-dimensional code is visually very obvious, and it is easy to copy it with a normal copying machine or other simple method. The invisible dot code is visually secret. The invisible dot code is generated by color micro dots 11 which are hard to see with the naked eye, and are arranged in a similar random combination, and then embedded in the background text or image. Because of the visual concealment, it is impossible to copy invisible dot codes with ordinary copiers or some simple methods. In addition to visual concealment, the encoding method and encoding content of the invisible dot code are also secret. The position of the color micro-dot 11 in the invisible dot code is nearly random. If you do not know the encoding method, you cannot make a fake code. of.

On each dot code identifier, the arrangement of the color micro dots 11 is unique, like a human fingerprint. No two fingerprints are the same, and the arrangement of the color micro-points 11 without any two anti-counterfeit labels is the same; that is, one anti-counterfeiting mark, one arrangement, and no repetition. It is worth noting that there are many ways to ensure that each permutation is unique. One of them is to give each anti-counterfeit identification 1 a separate number. In this embodiment, the anti-counterfeiting identification 1 is encoded with a 26-digit decimal number. The multi-dimensional code is represented by a 26-digit decimal number. The orderly arrangement of the 26-digit decimal number ensures the uniqueness of the anti-counterfeit mark 1. Figure 3 is a one-to-one correspondence between the anti-counterfeit mark and the 26-digit decimal number in this embodiment. In Figure 3, "54321098765432109876543210" is a 26-digit decimal number.

The common method of counterfeiting is imitation and copying. First, imitate a real thing, and then copy it in large quantities. The uniqueness of the anti-counterfeiting label 1 makes the common counterfeiting method completely unsuccessful, because there is only one authenticity anti-counterfeiting identifier for the same appearance. When multiple anti-counterfeit identifiers 1 with the same number appear on the market, the system will issue a warning and automatically abolish the counterfeit security identification number in the background server 3. Such anti-counterfeiting mechanisms make counterfeiting more than worth the loss.

4 is a schematic view showing the position of the anti-counterfeit mark in the embodiment. In this embodiment, the anti-counterfeit mark 1 is an identifier having randomness. Because the location of the anti-counterfeit mark 1 and its size define the arrangement of the color micro-dot 11 on the anti-counterfeit mark 1, and because the position and size of the anti-counterfeit mark 1 are random to some extent, the color micro-dot 11 on the anti-counterfeit mark 1 is To some extent also The anti-counterfeiting function of the anti-counterfeit mark 1 is greatly improved, because the completely random event is unpredictable, so that the counterfeiter cannot predict the background image 12 of the anti-counterfeit mark 1, nor can it create a false mark that can be confusing.

FIG. 5 is a schematic diagram of the multi-dimensional coding of the anti-counterfeit identifier in the embodiment. The encoding of the anti-counterfeit identifier 1 in this embodiment is multi-dimensional, and includes the encoding of the carrier 13 and the encoding of the anti-counterfeiting identifier 1 position. A complete anti-counterfeit identification 1 code consists of 26 decimal digits. This large capacity can meet the coding needs of all goods produced in the current and future years. For the coding method of the identification, please refer to the Chinese patent: ZL03145092, and the US patent: 6256398, 6577748, 6819776, 7123742.

The multidimensionality of the code allows any point or any small area on the carrier 13 to be defined by multidimensional coordinates, and the defined area can be defined as a link hotspot. When the coordinates (Χ, Υ, Ζ) scanned by the mobile phone fall within a certain defined area, the corresponding link hotspot can be activated to display the link information on the mobile phone. For example: (Χ, Υ, Ζ) is a point (Χ, Υ) in the description carrier (Ζ). For another example: (R, X, Y, Z) is a circle describing the carrier (Z) with (X, Y) as the center and (R) as the radius. Referring to the above figure, hot spot 1 is a circle defined by (R1, X1, Y1, Z1), and hot spot 2 is a circle defined by (R2, X2, Y2, Z1). When the coordinates (X, Y, Z) scanned by the mobile phone fall within the range of the hot spot 1, the hot spot 1 is activated, and the link information of the hot spot 1 is displayed on the mobile phone. When the coordinates (Χ, Υ, Ζ) scanned by the mobile phone fall within the range of the hotspot 2, the hotspot 2 is activated, and the link information of the hotspot 2 is displayed on the mobile phone. If (Χ, Υ, Ζ) does not fall within any of the logos, no link hotspots are activated and no link information is displayed.

Fig. 6 is a schematic diagram showing the high resolution and overlapability of the anti-counterfeit mark in the embodiment. In Fig. 6, hot spot 1 is a circle defined by (Rl, XI, Yl, Z), and hot spot 2 is a circle defined by (R2, X2, Y2, Z). The areas defined by Hotspot 1 and Hotspot 2 overlap each other. When the coordinates (X, Υ, Z) scanned by the mobile phone fall within the hotspot 1 and the hotspot 2 at the same time, since the center of the hotspot 2 is relatively close, the hotspot of the hotspot 2 is activated, and the content of the hotspot 2 is displayed. . It can be seen that the resolution between hotspots is defined by the resolution of multidimensional coordinates. Since the resolution of multidimensional coordinates is usually less than one millimeter, the resolution between hot spots is very high.

FIG. 7 is a schematic structural diagram of the identifier interpreter in the embodiment; the identifier interpreter 2 in the embodiment includes a hardware and a software, the hardware is a mobile phone, and the software is an application on the mobile phone. Specifically, the identifier reader 2 includes an image capturing unit 21, a main control unit 22, a communication unit 23, and a display unit 24; wherein the camera unit 21 is configured to acquire a digitized image of the anti-counterfeit label 1, and the main control unit is configured to control each unit ( The communication unit 23 and the display unit 24) perform corresponding operations, the communication unit 23 is used for communication with the background server 3, and the display unit 24 is for displaying information.

The embodiment further relates to a method for embedding an invisible point code in a digitized file, the flow chart of which is shown in FIG. In Figure 9, the method for embedding the invisible point code in the digitized file includes:

Step S11 converts a digitized file into a digitized image and uses the digitized image as a background image of the anti-counterfeit logo: In this step, first convert a digitized file into a digitized image, and then use the digitized image as a digital image. Background image of the anti-counterfeiting logo.

Step S12 calculates the coordinate position of the current color micro-dot in the background image according to the set encoding mode: In this step, press Step S13 calculates the local color of the background image by using the position of the color micro-point as a fixed point: In this step, the local color of the background graphic is calculated by using the coordinate position (X, Y) of the color micro-point as a fixed point.

Step S14 Embed the reverse color or yellow color of the local color in the position of the fixed point in the background image: In this step, the reverse color or yellow color of the local color is embedded in the fixed point position (X, Y) in the background image.

Step S15: determining whether all the color micro-dots are embedded in the background image: In this step, determining whether all the color micro-dots are embedded in the background graphic, and if the result of the determination is yes, executing step S16; otherwise, Step S17 is performed.

Step S16 Ends the embedding operation: If the result of the above step S15 is YES, the step is executed. In this step, the embedding operation is ended.

Step S17: Acquire the next color micro dot: If the result of the above step S15 is no, the present step is executed. It is worth mentioning that after performing this step, the process returns to step S12 until all the color micro dots are embedded in the background image.

For the calculation methods related to the above steps S12 and S13, please refer to the Chinese patent: ZL03145092, and the US patents: 6256398, 6577748, 6819776, 7123742. In this embodiment, the invisible coded content of the anti-counterfeit mark can be directly embedded in a digitized file, and the layout of the file itself does not need to be modified. This method provides convenience in use, improves the difficulty of counterfeiting, and does not destroy the aesthetics of the original document.

This embodiment further relates to a method for forming an anti-counterfeit label, and a flowchart thereof is shown in FIG. In Figure 10, the method for forming the security label includes:

Step S21 randomly generates a digitized file and converts it into a digitized image: In this step, a digitized file is randomly generated, and the digitized file is converted into a digitized image.

Step S22: transmitting the encoded information or the digitized image of the anti-counterfeit identifier to the background server: In this step, the code of the anti-counterfeit identifier or the digitized image (the image of the digitized file) is transmitted to the background server, so that the anti-counterfeit identifier is The background image is compared with the corresponding background image in the background server.

Step S23 embed the invisible point code of the anti-counterfeiting identifier in the digitized file: In this step, the invisible point code of the anti-counterfeiting identifier (which is encoded into multi-dimensional encoding) is embedded in the digitized file, and the embedding method is shown in FIG. 9 above.

Step S24: setting the information fed back when the anti-counterfeiting identifier is queried and transmitting the feedback information to the background server: in this step, when the anti-counterfeiting identifier is queried, the information (response information) of the entire page of the interpreter is identified, and the definition is The content and related data are transmitted to the backend server; the feedback information includes relevant authentication results or/and text and/or images or/and web pages and/or video or/and advertisements.

Step S25 Prints the digitized file embedded with the invisible dot code on the carrier: In this step, the digitized file in which the invisible dot code is embedded is printed on the carrier (tag carrier).

Step S26: Arranging a plurality of anti-counterfeit labels from the printed carrier arbitrarily or according to a certain rule: In this step, a plurality of anti-counterfeit labels are divided (cut out) from the printed carrier arbitrarily or according to a specific method. , it can be attached to the product as an anti-counterfeit label.

In the above method of forming the security label, since the digitized files are randomly generated, the randomness of each of the security labels can be ensured. And because of the use of invisible color micro-dots and multi-dimensional encoding, it is possible to ensure the privacy and uniqueness of each security label. In addition, since all the security labels are on the same carrier and have the same response when querying, there is no need to define a special area for each security label, and many security labels can be arbitrarily cut out from the carrier. use. Such a method of formation can greatly facilitate the user. In addition, it is worth noting that this method is not only a method of forming an anti-counterfeit label, but also a method of browsing related information provided by the manufacturer or the manufacturer on the product or on the anti-counterfeit label or on the trademark or on the package.

This embodiment further relates to a method for interpreting an anti-counterfeit mark, and a flowchart thereof is shown in FIG. In Fig. 11, the interpretation method uses the built-in camera sensor of the mobile phone to obtain a digitized image of the anti-counterfeit logo, and uses the built-in computer of the mobile phone to decode the code embedded in the image. The method further utilizes the built-in communication function, timing and positioning function of the mobile phone to transmit the location of the mobile phone, the identity of the mobile phone, the scanning time and the scanned image, etc. to the background server during scanning. The interpretation method is operated online with the background server to comprehensively identify the authenticity of the logo and display the identification result on the screen of the mobile phone. The interpretation method includes:

Step S31 identifies the interpreter scanning the anti-counterfeiting identifier: In this step, the identifier interpreter scans the anti-counterfeiting identifier. Specifically, the anti-counterfeit logo is scanned using the camera (camera) function of the logo reader.

Step S32: extracting the current digitized image from the video data stream of the identifier reader: In this step, specifically from the mobile phone Step S33 extracts the invisible point code from the digitized image, and decodes it to obtain a multi-dimensional coordinate: In this step, the invisible point code is extracted from the digitized image, and is decoded to obtain a multi-dimensional coordinate (X, Y). Where (Χ,Υ) is the position of the invisible point code on the carrier, (Υ) is the encoding of the carrier.

Step S34: The decoded parameter is transmitted to the background server: In this step, the decoded parameter is transmitted to the background server (background system), and the decoded parameters include scan image, multidimensional coordinates, query time, query location, and identifier reader. Identity Information.

Step S35: The background server uniquely identifies the anti-counterfeiting identifier and returns the authentication result to the identifier interpreter: in this step, the background server (background system) is used to uniquely identify the identifier. The parameters required for identification include multidimensional coordinates, query time, query location and identification reader identity information; if the authentication fails, the result is transmitted back to the identification reader (specifically the mobile phone) and displayed on the identification reader (specifically the mobile phone) Related failure information.

Step S36: The background server compares the scanned image with the background image stored in advance and returns the comparison result to the identifier reader: in this step, the background server (background system) is used to compare the scanned image with the previously stored logo background image. Correct. If the comparison fails, the result is sent back to the phone and the relevant failure message is displayed on the phone.

Step S37: querying the background database, extracting the first data corresponding to the coordinates, and transmitting the first data back to the identifier reader: In this step, querying the background database, extracting the first data corresponding to the multidimensional coordinates, and A data is sent back to the phone.

Step S38: displaying the first data on the identifier reader: In this step, displaying first data corresponding to the decoded coordinates (multidimensional coordinates) on the mobile phone, the first data including the identification result or/and the related text or / and images or / and web pages / / and short films.

In this embodiment, the anti-counterfeiting identifier has three security features: privacy, uniqueness, and randomness. These three characteristics are three layers of anti-counterfeiting protection for anti-counterfeiting. Concealment includes the content of the anti-counterfeit mark is almost invisible to the naked eye, and the anti-counterfeit mark code is not disclosed, which protects the appearance and coded content of the anti-counterfeit mark. Uniqueness means that the visual image of the anti-counterfeit logo is unique. Just like a human fingerprint, no two anti-counterfeit logos are the same, and the protection anti-counterfeit logo cannot be copied in large quantities. Randomness means that the content of some anti-counterfeiting labels is random and unpredictable, and its protection of anti-counterfeiting labels cannot be impersonated. The above-mentioned interpretation method in this embodiment combines these three characteristics, so that the anti-counterfeiting function of the anti-counterfeiting mark is exponentially increased. If a key is used to open the door for a metaphor, the comprehensive identification of the anti-counterfeiting mark requires three keys to open three doors. The first key is the encoding method, and the first door is the colored micro dot in the anti-counterfeiting mark. Only knowing the correct encoding method can successfully decode the color micro dots in the logo, thus obtaining the second key. The second key is a multi-dimensional coordinate, and the second door is the identification of the uniqueness of the anti-counterfeiting mark. The mutual correspondence between the multidimensional coordinates and the anti-counterfeiting mark is predefined. Generally speaking, according to statistical data, such as query time, location, number of times, and the mobile phone used for the inquiry, etc., it is possible to accurately determine whether a number to be queried (26-digit decimal number of the anti-counterfeit mark in this embodiment) only one. The number and query statistics of each anti-counterfeit identifier are stored in the background server. Only when the query number is valid, has been issued, and is the only condition, the third key can be extracted from the background server. The third key is the background image of the anti-counterfeit logo, and the third door is the comparison of the extracted background image with the background image of the identified logo. The third door can only be opened when the extracted background image matches the background image of the identified logo.

In this embodiment, the above step S33 can be further refined, and a specific flowchart thereof is shown in FIG. In Figure 12, the above step S33 further includes:

Step S331 automatically detects various parameters of the invisible point code from the digitized image: In this step, parameters of various invisible point codes are automatically detected from the digitized image, and the detected parameters include the coding type and the coding dimension. Number, size and orientation, etc. The digitized image is obtained using the camera function of the mobile phone.

Step S332: Decoding the invisible point code according to the detected parameter to obtain a multi-dimensional coordinate: In this step, the invisible point code is decoded according to the detected parameter to obtain a multi-dimensional coordinate, for example: (Χ, Υ, Ζ. The dimension of the multidimensional coordinates is determined according to the parameters of the automatically detected invisible point code. For details, please refer to Chinese patent: ZL03145092, and US patents: 6256398, 6577748, 6819776, 7123742. This decoding operation utilizes the computing functions of the mobile phone.

It is worth mentioning that, in this embodiment, the above steps S331 and S332 and their calculations are all completed on the mobile phone. In this embodiment, the above step S35 can be further refined, and a specific flowchart thereof is shown in FIG. Step S35 actually provides an identification method for the uniqueness of the anti-counterfeiting mark. The identification principle of the identification method is that the same anti-counterfeit mark cannot appear in different places in a very similar time. If something like this happens, then one of the anti-counterfeit signs is fake or two Together, the true security logo is often associated with the true security feature. Because each security mark (the finished product is a label) corresponds to a batch number, the probability of the true security mark of the same batch number is high. Moreover, the probability of false anti-counterfeiting labels being together in the sales channel is also very high. If a fake anti-counterfeiting mark often appears in a place, then the probability of a fake anti-counterfeit mark with the same batch number in the place is particularly high. Another basis for the identification is that the probability that the fake anti-counterfeiting identifier is queried is higher than the probability that the true anti-counterfeiting identifier is queried, and the probability that the same batch number or the same encoded fake anti-counterfeiting identifier is queried is particularly high. Based on the principles of these identifications and probability features, a mathematical model can be built to calculate the probability of uniqueness. Generally speaking, according to statistical data, such as the frequency of the query, the time of each query, the location of the query, and the characteristics of the mobile phone used in the query, it is possible to accurately determine whether a queried identifier is unique. A fake anti-counterfeit logo can be made exactly like a real anti-counterfeit logo, but it is difficult to imitate the content and query history of a true anti-counterfeit logo. Such an interpretation method directly challenges the technology of fraud, making fraud very difficult. Even when the fake anti-counterfeit mark is exactly the same as the true anti-counterfeit mark, it can be recognized. For example: When the query location is the same, the query phone is different, and the query time is different, even if the query frequency is very high, the unique probability of the identifier being queried is still high; when the query location is different, the query phone is different, and the query time is similar, The query ID is certainly not unique, because an anti-counterfeit logo cannot appear in two places at the same time. In the background server, the query statistics of each anti-counterfeit identifier are stored. Only when the anti-counterfeit identifier that is queried is valid, has been issued, and only under the condition of a high probability, the unique identification can be passed.

In Figure 13, the above step S35 further includes:

Step S351: transmitting the code of the anti-counterfeit identifier, the identity of the identifier reader, the query time, and the query location to the background server: In this step, the scan parameters are: the number of the anti-counterfeit identifier (code), the characteristics of the mobile phone (identity of the identifier reader) ), query time and query location, etc. are sent to the background server (background system).

Step S352 calculates the probability of uniqueness according to the code of the identifier, the identity of the identifier, the query time, the query location, and the scan record: In this step, the unique probability is calculated according to the scan parameter and the scan record.

In step S353, it is determined whether the probability is greater than a preset threshold. In this step, it is determined whether the calculated likelihood is greater than a preset threshold. If the result of the determination is yes, step S354 is performed; otherwise, step S355 is performed. .

Step S354 returns the information of the successful authentication to the identifier reader display: if the result of the above step S353 is YES, that is, the uniqueness authentication is successful, the step is executed. In this step, the information of the successful authentication is returned to the identification reader display.

Step S355 returns the information of the authentication failure to the identification reader display: if the determination result of the above step S353 is negative, that is, the uniqueness verification fails, this step is performed. In this step, the information of the authentication failure is returned to the identification reader display.

In this embodiment, the above step S36 can be further refined, and a specific flowchart thereof is shown in FIG. 14. Step S36 actually provides an authentication method for the randomness of the anti-counterfeiting identifier. A prerequisite for the authentication method of the randomness is to pre-store a completely-identified background graphic in the background system (background server), so as to be obtained from the scan. The background image is relatively large. It is worth noting that the background image obtained by the scan is incomplete and distorted.

In Figure 14, the above step S36 further includes:

Step S361: extracting the first background image of the anti-counterfeit mark from the scanned image: In this step, the first background image of the anti-counterfeit mark is extracted (extracted) from the scanned image (in order to distinguish from the background image below, The background image extracted in this step is called the first background image).

Step S362 extracts a second background image of the anti-counterfeiting identifier corresponding to the encoding of the anti-counterfeiting identifier from the background database, and compares the scanned first background image with the second background image extracted in the background database to obtain a The first value describing the degree of similarity: In this step, specifically, the second background image of the anti-counterfeiting identifier corresponding to the anti-counterfeit identification code is extracted from the background database, and the first background image and the background database are scanned. The two background images are compared to obtain a first value describing the degree of similarity. How to compare two images is a mature and common technique.

Step S363: determining whether the first value is greater than the set value: In this step, determining whether the first value is greater than the set value, if the result of the determination is yes, executing step S364; otherwise, executing step S365.

Step S364 returns the information of the successful authentication to the identifier reader for display: If the result of the above step S363 is YES, that is, the randomness authentication is successful, the step is executed. In this step, the information of the successful authentication is returned to the identification reader for display.

Step S365 returns the information of the authentication failure to the identifier reader for display: If the result of the above step S363 is negative, that is, the randomness authentication fails, this step is performed. In this step, the information of the authentication failure is returned to the identification reader for display. The methods of pseudo-identification are:

Step S41: transmitting the query parameter of the identifier to the background server: In this step, the query parameter of the identifier is transmitted to the background server; the query parameters include the security identifier code, the query time, the query location, and the identity of the query identifier reader. Or feature.

Step S42: The background server collects the query record related to the anti-counterfeit identification code: In this step, the background server collects the query record related to the anti-counterfeit identification code of the query; the query record includes the anti-counterfeit identification code (strictly speaking, the anti-counterfeit tag coding) The batch number of the corresponding anti-counterfeit identification or / and the distribution frequency of the anti-counterfeit identification or / and the distribution of the query time or / and the distribution statistics of the query location or / and the frequency of counterfeiting at the query location or / and the frequency of counterfeiting with the same batch number Or / and the frequency of counterfeiting with the same encoding.

Step S43 calculates the probability of uniqueness according to the query parameter and the data in the query record: In this step, according to the query parameter and the statistical data in the query record, the probability of uniqueness is calculated according to a mathematical model. The mathematical model can be a simple method, such as: performing a linear weighted calculation on each input data, or using other more complicated methods.

Step S44 determines whether the probability is greater than a preset threshold: In this step, it is determined whether the calculated likelihood is greater than a preset threshold, and if so, step S45 is performed; otherwise, step S46 is performed.

Step S45: It is determined that the anti-counterfeiting flag is true: if the result of the above step S44 is YES, the step is executed. In this step, it is determined that the anti-counterfeiting flag is true, that is, the uniqueness is successfully authenticated, and the successful result is returned to the identifier interpretation. Display.

Step S46: It is determined that the anti-counterfeiting flag is false: If the result of the above step S44 is no, the step is executed. In this step, it is determined that the anti-counterfeiting flag is false, that is, the uniqueness authentication fails, and the result of the authentication failure is returned to the identifier interpretation. Display.

In the above method of identifying the authenticity of the anti-counterfeiting mark, the basis for distinguishing between true and false is the uniqueness of the anti-counterfeiting mark. The parameters required to distinguish between true and false include the query parameters of the identifier reader and the query records of the anti-counterfeit identifiers in the background server. Specifically, the rule of distinguishing between true and false is to see if the same anti-counterfeiting mark appears in a different place in a very similar time. If there is, one of the anti-counterfeit marks is false or both anti-counterfeit marks are false. Another rule for distinguishing between true and false is that the object is clustered together, that is, the fake anti-counterfeiting mark is often associated with the fake anti-counterfeit mark, and the true anti-counterfeit mark is often associated with the true anti-counterfeit mark. Another rule to distinguish between true and false is that the probability of a false security logo being queried is particularly high. According to the mode in which the anti-counterfeiting mark is queried (including time, place, number of times, data such as the identifier reader used for the inquiry), the authenticity of the anti-counterfeit mark can be accurately determined. A fake anti-counterfeit logo can be created exactly like a real anti-counterfeit logo, but it is difficult to imitate the content and query history of a true anti-counterfeit logo. Such identification methods directly challenge the technology of fraud, making fraud very difficult. Even when the fake anti-counterfeit mark is exactly the same as the true anti-counterfeit mark, it can be recognized.

The embodiment further relates to a method for changing the ownership of an anti-counterfeiting identifier, and the flowchart thereof is as shown in FIG. 16. The anti-counterfeiting identification attribute refers to the belonging relationship between the anti-counterfeiting identification and the identifier interpreter (in this embodiment, specifically the mobile phone). An anti-counterfeiting logo can have several tenure states: 1) single, no right to belong to the person, 2) engaged, pending ownership, 3) married, entitled to personal status. The anti-counterfeiting logo can enter the engaged state from a single person; it can also enter the married state from the engagement; it can also enter the single state from the married state; it can also enter another married state from one married state. However, the anti-counterfeiting logo cannot enter the engaged state directly from the married state. Changing the security of the anti-counterfeiting logo is to establish or change the relationship between the anti-counterfeiting logo and the user of the mobile phone. It is worth noting that changing the security of the anti-counterfeiting logo can be applied to the certification of second-hand goods. The management methods involved include: anti-counterfeit identification, mobile phones with camera and Internet access, and back-end servers with online functions.

In Figure 16, the method for changing the security of the security identification includes:

Step S51 proposes an anti-counterfeiting identification change request: In this step, the method of proposing the anti-counterfeiting identification change request (the right change request) is similar to the decoding method of the anti-counterfeit identification image. The implementation of the anti-counterfeiting identity change request is implemented by scanning the anti-counterfeiting identifier.

Step S52: Display the ownership change menu according to the ownership status of the anti-counterfeiting identifier: In this step, the ownership change menu is displayed according to the ownership status of the anti-counterfeiting identifier.

Step S53 selects an option from the change menu and performs related operations of the option: In this step, an option is selected from the change menu and the related operation of the option is performed; the above options include obtaining the ownership of the security mark or assigning the ownership of the anti-counterfeit mark or giving up the anti-counterfeit mark. ownership. Specifically, after the user selects the option of obtaining the ownership of the anti-counterfeiting identifier, after confirming that the anti-counterfeiting identifier is in the unlicensed state, the user enters the operation of acquiring the security identification ownership. After the user selects the option for ownership of the anti-counterfeiting mark, the user is confirmed to have the anti-counterfeit mark according to the characteristics of the mobile phone, and then enters the operation related to the ownership of the anti-counterfeiting mark. When the user chooses to abandon the option of ownership of the security mark, confirm that the user has the security mark according to the characteristics of the phone, and then update the database record, so that For the present embodiment, the above-described flowchart of the method for acquiring the ownership of the anti-counterfeit mark is as shown in FIG. In Figure 17, the method for obtaining ownership of the security feature includes:

Step S61 displays the anti-counterfeiting identification ownership form and prompts the user to input the form content: In this step, the anti-counterfeiting identification ownership form is displayed, and the user is prompted to input the form content.

Step S62: The system determines, according to the scan record, whether the user has the control right of the anti-counterfeit identifier: In this step, the ownership of the anti-counterfeit identifier enters the judgment period, and the system determines whether the user has the control right of the anti-counterfeit identifier according to the scan record, and if the judgment result is yes Then, step S62 is performed; otherwise, step S64 is performed. It is worth mentioning that during the judgment period, the user can scan the anti-counterfeiting mark by changing the time or place to demonstrate the control of possessing the anti-counterfeiting mark. It is worth mentioning that, in this embodiment, the mobile phone user has sufficient control over the anti-counterfeiting identifier to be equal to the ownership of the identified object.

Step S63: The user obtains the ownership of the anti-counterfeit flag, and the system updates the ownership record in the database: If the result of the above step S62 is YES, the step is executed. In this step, according to the scan record, after the system confirms that the user has the control right of the anti-counterfeit mark, the system will display the security status judgment of the anti-counterfeit mark, and the anti-counterfeit mark exits the judgment period and enters the state of the right owner. At the same time, the user obtains ownership of the anti-counterfeiting identity and the system also updates the database ownership record.

Step S64 quits the current operation: If the result of the above step S62 is no, the present step is executed. In this step, the current operation is exited.

In this embodiment, the background server is an arbitrator's role, and one of its duties is to verify the authenticity of a claim of ownership and make a judgment on the claim. If the marker is in a public place, anyone can use the mobile phone to scan the logo to make a claim. Only after the claim is verified, the background server makes the decision of the ownership and updates the ownership record in the database. The method of verifying the ownership claim is that the back-end server acts as an arbitrator, and the mobile phone user's control over the anti-counterfeiting identification is determined according to the anti-counterfeiting identification query record. The authentication method of the tenure claim is to require the user to scan the anti-counterfeit logo at different times or places to demonstrate possession of control over the anti-counterfeiting logo. The principle of the method is to effectively determine whether the mobile phone user has actual control over the identifier based on data such as the time, location and characteristics of the mobile phone. For example, if a mobile phone user scans the same anti-counterfeit logo in a different location, the probability that the user has control is very high. If a user is in the same place and scans the same anti-counterfeit identifier multiple times at different times, the chances of the user having control are also very high. When the probability is higher than a threshold value, the ownership is determined to belong to the mobile phone user. In addition, the verification and judgment of the tenure claims take a period of time and is called a pending period. The length of this waiting period is not certain. Only when the system receives sufficient scan data, the system makes a ruling.

For the present embodiment, the flow chart of the method for assigning the ownership of the anti-counterfeiting mark is as shown in FIG. 18. In the method of assigning the security of the anti-counterfeiting mark, the anti-counterfeit mark can be displayed on the screen of the mobile phone, and the content of the anti-counterfeit mark can also be read from the screen of the mobile phone. The transfer of the ownership of the anti-counterfeiting mark does not need to be pending. After adding a special code to the code of the original anti-counterfeit mark, it is embedded in the ownership of the anti-counterfeit mark and then displayed on the screen of the mobile phone. The transfer of ownership is done through an action, that is, the recipient scans the identity of the logo on the mobile phone with the mobile phone. This ownership displays both visual information that communicates with the user and functional information that communicates with the machine. In this action, the ownership indicates that the content is given to the viewer and the recipient, and the special code in it informs the backend server to transfer ownership of the security token from the transferor to the recipient.

In Figure 18, the method for assigning ownership of the anti-counterfeiting mark includes:

Step S71: Generate a background image according to the content of the ownership of the security symbol: In this step, a background image is generated according to the content of the ownership of the security symbol.

Step S72: adding the code of the transfer ownership to the code of the transfer security mark to form the first code, and embedding the first code into the background image of the ownership: In this step, the code of the transfer ownership is added to the transfer security mark. The first code is formed on the code, and the first code is embedded in the background image of the ownership.

Step S73: displaying the ownership embedded in the first code on the first identifier reader of the transfer party: in this step, specifically, on the first identifier reader (specifically, the mobile phone of the transferor) of the transferor (transfer) The ownership code embedded in the special code (first code) is displayed.

Step S74: The receiver scans the ownership of the first identifier reader of the transfer party with the second identifier reader: in this step, the receiver (recipient) scans the transfer party with the second identifier reader (receiver's mobile phone) ( Ownership of the first identification reader (the transferor's mobile phone) on the ownership.

Step S75: The recipient confirms the change of ownership on the second identification reader: In this step, the recipient confirms the change of ownership on the second identification reader (receiver's mobile phone). The database records are updated to transfer the ownership of the anti-counterfeiting mark from the transferor (granter) to the recipient (recipient). In summary, in the present embodiment, the anti-counterfeit identification not only provides visual depiction of images and images, but also provides a hidden link hotspot, and links the anti-counterfeit identification and related identification information through the network. This anti-counterfeit mark can be widely used in various fields. Anti-counterfeit identification content can be printed directly on paper items such as tickets, stamps, banknotes, stocks, confidential documents, land rights, housing rights, and the like. Anti-counterfeiting logo content can also be printed directly on plastic items, such as credit cards, financial cards, driver's licenses, identification cards, licenses, ID cards, passports, etc. With a laser laser engraving machine, the anti-counterfeiting label content can also be printed directly on metal objects. Anti-counterfeit identification content can even be displayed on the screens of TVs, computers and mobile phones. In addition to this, it is also possible to pre-manufacture an anti-counterfeit label and then attach the anti-counterfeit label to the item. Such applications include packaging of general merchandise and merchandise, such as: food, medicines, boutiques, cigarettes, wine, sporting goods, and electronics.

For a long time, although the government has made a lot of efforts in the field of counterfeiting, counterfeiting continues to expand. One of the main reasons is the lack of high-tech market supervision. The embodiment provides a set of invisible point code anti-counterfeiting system with high technical threshold, high anti-counterfeiting strength and convenient use. The invisible point code anti-counterfeiting system integrates digital anti-counterfeiting technology and printing process, and the combined operation of the mobile phone identification and the online database is found to be counterfeit. The first time, the user will be automatically notified, the manufacturer and the relevant government departments. Such measures provide a mechanism for automatic market supervision, enabling the relevant government departments to immediately investigate the source of counterfeiting and more effectively combat counterfeiting in the market.

At present, the anti-counterfeiting labels on the market, such as general barcodes, two-dimensional codes, holograms, watermarks, and fingerprints, do not have the advantage of identifying multiple functions, and the anti-counterfeiting labels and the anti-counterfeiting labels cannot overlap each other. The restrictions make these anti-counterfeiting labels not easy to apply to small objects, such as: small bottles, cosmetics, etc. In this embodiment, a small area of the anti-counterfeit identifier may include a plurality of link hotspots, and has multiple functions, and the areas occupied by the link hotspots may be independent of each other, or may overlap each other, and link The resolution between hotspots can be as small as a few millimeters.

In general, the randomness and readability of anti-counterfeiting labels are contradictory. Increasing randomness reduces readability and improves readability and reduces randomness. Similarly, the privacy and readability of anti-counterfeiting labels are also contradictory. In the current technology, there are many technologies with high readability, low concealment or low randomness, such as case 2 in the background art; there are also techniques with high randomness and low readability, such as case 3 in the background art; There are also techniques that are high in privacy and low in readability, such as Case 4 in the background. In this embodiment, there is a new breakthrough in the interpretation method. The interpretation method solves the contradiction between concealment, randomness and readability, so that the anti-counterfeiting logo can have good concealment, complete randomness and 100% machine reading ability.

This embodiment has a new breakthrough in the security of anti-counterfeiting. The ability to identify counterfeiting has long been an important indicator of anti-counterfeiting technology. When the counterfeit and the authenticity are 100% identical, the existing identification technology is immediately invalid. In the present embodiment, even if the defective product is identical to the genuine product, the recorded record can be effectively judged based on the uniqueness and range of the security mark to be counterfeited.

There are two phenomena in the anti-counterfeiting technology on the market today. One is convenient for testing, but the technical quality is too low and easy to crack. The second is the high quality of the technology, but the detection is inconvenient, and some need a long time, which is not economical. In addition, there is no effective method in the market that enables consumers to machine the anti-counterfeiting mark. Such restrictions greatly hinder the promotion and application of anti-counterfeiting technology. In contrast, the present embodiment provides a self-service interpretation method, which is characterized by high technical quality, is not easy to be cracked, and detection is convenient and fast. The user uses the mobile phone to identify the authenticity of the product. It only needs one action (that is, the anti-counterfeiting mark). It does not need to press any other keys, and only a few seconds can get an accurate answer.

Generally speaking, in an anti-counterfeiting technology system, the weakest place is the secret of product manufacturing. It is easy to find the way to crack when the fraudulent person gets the secret of manufacturing or steals the coding method. The embodiment combines various anti-counterfeiting measures (such as anti-counterfeiting identification code, background graphic, mobile phone recognizer or mobile phone reader, background server, authentication method, etc.), even in the case where the encoding method is stolen and the identification manufacturing secret is disclosed. The anti-counterfeiting system is still safe.

The above-mentioned embodiments are merely illustrative of several embodiments of the present invention, and the description thereof is not to be construed as limiting the scope of the invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of the invention should be determined by the appended claims.
