Detailed Description
The technical solutions of the present invention will be described clearly and completely through the following detailed description, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an article identification system according to an embodiment of the present invention, and the technical solution according to the embodiment of the present invention is implemented by the system. The main structure of the article identification system will be described with reference to fig. 1.
An article identification system comprising: the system comprises a registration terminal 100, an authentication request terminal 200 and a server 300, wherein the server 300 is in communication connection with the registration terminal 100 and the authentication request terminal 200 respectively, the article identification system further comprises a carrier 1 with an identification area image 10, and the identification area image 10 carries identification information of the article.
The registration terminal 100 may be a network device installed with an application, and such network device may be embodied in hardware as a desktop computer, a laptop computer, a tablet computer, a smart phone, a handheld computer, or any other wired or wireless processor-driven device having an internal or external camera. The system software can be an operating system integrated with a web browser or an operating system installed with a special application; such an operating system may be a windows-series operating system, a Linux operating system, or the like, or may be Android, IOS, or the like in a mobile platform.
The registration terminal 100 may be a product manufacturer, a product provider, a brand manufacturer, or any other object provider side terminal that needs to identify an identity, where the registration terminal 100 is configured to obtain identity information of an object and encrypt and send the identity information to the server 300 for registration, and of course, the registration terminal 100 may also be the same as the server 300, that is, the registration terminal 100 stores the identity information of the object in its own database, and the registration terminal 100 may be a physical device or a device, unit, or module disposed in the physical device.
The authentication requestor 200 may also be a network device with an installed application, and such network device may be hardware including a desktop computer with an internal or external camera, a laptop computer, a tablet computer, a smart phone, a handheld computer, or any other wired or wireless processor driven device. The system software can be an operating system integrated with a web browser or an operating system installed with a special application; such an operating system may be a windows-series operating system, a Linux operating system, or the like, or may be Android, IOS, or the like in a mobile platform. The authentication request terminal 200 may be a physical device, or may be a device, unit, or module provided in the physical device. Preferably, the authentication request terminal 200 is a handheld device such as a smart phone or a tablet, which is convenient for the user to use.
The verification request end 200 may be a product user, a commodity purchaser, and any user side terminal that needs to identify the identity of an article, and the verification request end 200 is configured to obtain the identity information of the article to be identified, encrypt and send the identity information to the server 300 to compare with corresponding registration information, and receive a comparison result.
The server 300 may be a server provided by an article identity information registrant, a public cloud server, a server provided by a third-party authentication service provider, or the like. The server 300 is generally a database server, and the database is used for storing the article identification information obtained by the registration terminal 100, and other related information, such as application requirement data, business rules, client capability data, application market data, customer data, and identification information comparison result record data. The server 300 may employ one or more computing devices, which may be arranged, for example, as one or more server banks or groups of computers or other devices. For example, the multiple computing devices may collectively comprise a cloud computing resource, a grid computing resource, and/or any other distributed computing apparatus.
The carrier 1 may be an article itself, an article packaging bag, or a label of an article, or may be a separately prepared adhesive film that can be attached to an article. Depending on the type, shape and purpose of identification, the identification area image 10 is easy to form without affecting the identification effect. For example, a bottle with a seal may be used as the carrier 1, a label of the bottle may be used as the carrier 1, or a film may be used as the carrier 1 of the bottle identification area image 10; but when identifying the identity of the express delivery object, the adhesive film is more suitable to be used as the carrier 1. The identification area image 10 may be a part of the carrier 1, or may cover the carrier 1, and one or more identification area images 10 may be provided on the article.
More specifically, referring to fig. 2, the identification area image 10 includes: a natural texture area 12, an additional information area 14, and a locator 16, the locator 16 being used to define the natural texture area 12 and to provide the identification area image 10 with a fixed identification range, determining the identity information of the item. The locators 16 are formed by printing or code-spraying, and are generally located at the vertices of the identification area image 10, like the start of a two-dimensional code, and the number of the locators 16 is not limited, and is preferably three. The additional information area 14 is formed in the form of a two-dimensional code and/or a bar code while the locator 16 is printed or sprayed, the information contained in the additional information area 14 may be a product serial code, a product LOT number, a production tracing code, a manufacturer code, a place of manufacture code, and information of traceable identity given to the article by any article provider, the additional information is a part of the identity information of the article, and the identity information may be unique identity information of the article, or identity information of a class of articles.
The natural texture area 12 has a random distribution pattern therein, and the random distribution pattern may be a regular pattern or an irregular pattern; the colors of the randomly distributed patterns can be the same or different, but the colors of the patterns are ensured to be different from the background color; the shape and color of the randomly distributed pattern are not limited to two, and may be three or more. Each random distribution pattern is composed of pixel points in the image, and each pixel point has specific coordinates and colors.
The random distribution pattern can be a substance which is not easy to diffuse, such as doped fibers or fluorescent powder particles and the like in the production process of an article packaging bag or a label or a film, and then a natural texture area 12 is defined on the article packaging bag or the label or the film through a locator 16 to obtain the random distribution pattern with identity information; the label may be formed on a packaging bag, a label, a bottle body, or a film by spraying a code or printing ink. Due to the randomness of the doping process or the code spraying and printing process, the information carried by the randomly distributed patterns has complete randomness, and no person knows the identity information of the article before the natural texture area 12 is not defined, so that even the personnel inside the registration terminal 100 cannot reveal the identity information of the article.
Preferably, the random distribution pattern of the embodiment of the present invention is formed by randomly dispersing phosphor particles having at least two or more wavelengths in a visible light range based on emission peaks in a transparent carrier 1 such as an article packaging bag or a label or a film to form the random distribution pattern. The phosphor particles have at least partially the same excitation wavelength and the carrier 1 has light transmitting properties. The phosphor particles are invisible to the naked eye and when illuminated with a common excitation wavelength, the different phosphor particles dispersed in the carrier 1 emit light of a characteristic wavelength, exhibiting different colors. For example, red phosphor particles 12a and green phosphor particles 12b as shown in FIG. 3; red phosphor particles 12a and yellow phosphor particles 12c as shown in fig. 4 may be used. Because the fluorescent powder particles have more stable physical characteristics, the carried identity information is not easy to distort, and the fluorescent powder particles are not easy to identify under the condition of naked eyes, so that the randomly distributed patterns on the article are prevented from being damaged manually.
Each randomly distributed pattern in the natural texture region 12 is composed of a large number of small squares, i.e., pixels, in the image, as shown in fig. 5. Each pixel point has a definite position and color, and the attributes of the pixel points form the identity information of the article. The color and position of the pixel point of each random distribution pattern determine the information such as the shape, area, color, position and density presented by the random distribution pattern.
Wherein the pixel point location is an X/Y two-dimensional location coordinate defined for the origin of coordinates based on the locator 16. The RGB value is a color standard, and various colors are obtained by changing three color channels of red (R), green (G) and blue (B) and superimposing the three color channels on each other, RGB represents colors of the three channels of red, green and blue, and the standard almost includes all colors that can be perceived by human vision, and the RGB value of each color is different, and even some colors that cannot be distinguished by naked eyes, the RGB value can be different, and the accuracy of color identification is high. The RGB values each have 256 levels of brightness, including 0-255, e.g., black R, G, B values are 0, respectively; the R, G, B values of the white color are 255, and 255, respectively, the R, G, B values of the red pixels of the red phosphor particles 12a are 249, 9, and 31, respectively, and the R, G, B values of the green pixels of the green phosphor particles 12b are 13, 178, and 24, respectively, as shown in fig. 3.
The above is a simple introduction of the article identification system provided in the embodiment of the present invention, in which a randomly distributed pattern with identification information is provided on an article, the registration terminal 100 identifies the pixel coordinates and RGB values of the randomly distributed pattern to obtain the shape, area, coordinates, color, and other identification information of the randomly distributed pattern, and then stores the identification information in the server database to complete the article identification registration, and when the article arrives at the authentication request terminal 200, the authentication request terminal 200 obtains the identification information on the article by using the same identification process, and compares the identification information with the registration information in the server database, thereby identifying the identity of the article. The coordinates and the colors of the pixel points of the randomly distributed patterns and the shapes of the randomly distributed patterns are used as the identity information of the article, so that the accuracy of identity identification is greatly improved, and the cost for counterfeiting the identity information is greatly increased. The following describes in detail the process of registering, verifying and identifying an article according to the present invention with reference to fig. 1, and the following embodiments use the same devices or components as the article identification system and will not be described again.
Referring to fig. 6, fig. 6 is a schematic flow chart of an article registration method according to an embodiment of the present invention, which may include the following steps S101 to S103:
step S101, obtaining an identification area image on an article, and carrying out zooming processing on the identification area image to enable the identification area image to be zoomed to a preset size and pixels, wherein the identification area image comprises a natural texture area, an additional information area and a locator, the locator is located at the vertex of the identification area image, and the natural texture area is provided with a plurality of randomly distributed patterns.
The identification area image 10 on the article is acquired by a registered terminal device, and may be acquired by photographing or scanning. Because the pixels of different devices are different and the distances between the photographed or scanned images are different, the sizes of the pixels and the sizes of the images of the identification area 10 obtained by the different devices are different, in order to ensure that the obtained images of the identification area 10 have a uniform standard, the size of the pixel and the size of the image of the identification area 10 are preset, and zooming processing is performed during photographing or scanning to obtain a standard image.
Step S102, identifying the natural texture area to obtain natural texture information, wherein the natural texture information comprises coordinates, colors and shapes of the randomly distributed patterns.
The natural texture information is unique identity information of an article, wherein a specific identification process of the natural texture may be that the locator 16 is defined as an origin of coordinates, the coordinate value of the locator is (0, 0), the coordinate value of a pixel point of the randomly distributed pattern is read based on the origin of coordinates, since the background color of the natural texture region 12 is significantly different from the color of the randomly distributed pattern, the coordinate value of the pixel point is correspondingly recorded as (a, b) when the RGB value of the pixel point of the randomly distributed pattern is read, the identification process is surface identification, data is sequentially read on the whole natural texture region 12, and the coordinate and RGB value of the pixel point except the background color are recorded. After the pixel point coordinates and the RGB values of the randomly distributed patterns are read, the information such as the coordinates, the color, the shape, the area, the density and the like of the randomly distributed patterns can be calculated according to the pixel point coordinates and the RGB values.
The identification process may also be defined as the locator 16 being an absolute origin of coordinates with coordinate values of (0, 0), where we may refer to the absolute origin of coordinates as a first origin of coordinates; then, according to the horizontal direction of the absolute coordinate origin, the geometric center point of each random distribution pattern is determined as the relative coordinate origin, and the coordinate value is (X)0，Y0) Here we may refer to the relative coordinate origin as the second coordinate origin. Sequentially reading the coordinate of each pixel point from the geometric center point of the randomly distributed pattern as the center to the periphery, wherein the coordinate value is (X)a，Yb) Stopping reading when the background color RGB value is read, e.g. when the background color is black, stopping reading when the RGB value is 0, 0, 0Reading, so that the pixel point of each randomly distributed pattern has a coordinate value (X) relative to the origin of absolute coordinates0+Xa，Y0+Yb) The absolute coordinate origin and the relative coordinate origin are adopted to read the pixel point coordinates and the RGB values, so that errors caused by rotation of randomly distributed patterns can be prevented, and the reading amount can be reduced.
Preferably, in order to prevent misjudgment caused by non-human factors, redundancy correction capability may be provided when the natural texture region 12 is identified, and a tolerance range is set for a result obtained during image identification, so that the false rejection rate can reach an acceptable range.
The identification of the natural texture area 12 also includes the identification of the additional information area 14 to obtain additional information, which can be a product series code, a product LOT number, a production tracing code, a manufacturer code, a production place code and information of traceable identity given to the article by any article provider, and the additional information is part of the identity information of the article.
In order to improve the information security, an encryption operation may be performed after the natural texture information is obtained, the encryption algorithm may be an RSA algorithm or a hash algorithm, and the like, and the encryption factor is a part of the additional information, such as a manufacturer code or/and a product code or/and a place code, and the like. What encryption factor is used is already set when the additional information area 14 is set, and when the additional information area 14 is set, the additional information of different areas can be set to have different functions. And the additional information of some areas is used as an encryption factor, the additional information of some areas and the natural texture information are stored in a database together, and the additional information and the natural texture information are used as a search index of the natural texture information to determine a storage address of the natural texture information. Optionally, the additional information may also be encrypted.
Step S103, storing the encrypted natural texture information and the additional information identified from the additional information area in an article registration database.
When the registration terminal 100 is also the server 300, the registration terminal 100 directly stores the natural texture information and the additional information on the article, and when the server 300 is provided by a third-party service provider, the registration terminal 100 sends the information to the server 300 for storage after obtaining the natural texture information and the additional information on the article, thereby completing the article identity registration.
After the registration terminal 100 completes the identity registration of the article, the article usually enters a circulation state, and a user who obtains the same article has to identify whether the article obtained by the user is the article provided by the registration terminal 100, so that article authentication can be performed, a specific article authentication method flow is shown in fig. 7, fig. 7 is a schematic flow diagram of an article authentication method provided in an embodiment of the present invention, and the authentication method may include steps S201 to S204:
step S201, obtaining an identification area image on an article, and performing scaling processing on the identification area image to scale the identification area image to a preset size and pixels, wherein the identification area image comprises a natural texture area, an additional information area and a locator, the locator is located at the vertex of the identification area image, and the natural texture area has a plurality of randomly distributed patterns.
Step S202, identifying the natural texture area to obtain natural texture information, wherein the natural texture information comprises the shape, coordinates and color of the random distribution pattern.
Step S203, the encrypted natural texture information and the additional information identified from the additional information area are uploaded to a server, so that the server compares the natural texture information and the additional information with corresponding registration information.
Step S204, receiving a comparison result from the server.
The technical contents of steps S201 to S202 in the embodiment of the present invention correspond to the technical contents of the embodiment corresponding to fig. 1 to 6, and are not described herein again.
The registration information is article identity information stored in the server 300 by the registration terminal 100, the article identity information includes additional information and natural texture information, the additional information may be a product serial code, a product LOT number, a production tracing code, a manufacturer code, a place of manufacture code and information of traceable identity given to the article by any article provider, the additional information may be unique identity information of the article, or identity information of a class of articles, and the natural texture information is information of coordinates, colors, shapes and the like of randomly distributed patterns in the image 10 of the article identification area, and is identity information unique to the article. The authentication request terminal 200 obtains the article identification area image 10 in the same manner as the registration terminal 100, identifies the identity information of the natural texture area 12 and the additional information area 14, and finally sends the obtained natural texture information and the obtained additional information to the server 300 for comparison.
The server 300 searches for corresponding natural texture information according to the additional information sent by the verification request terminal 200, decrypts the natural texture information sent by the verification request terminal 200 and the stored natural texture information, compares the decrypted information, and if the comparison results are the same, the article obtained by the authentication request terminal 200 is the same as the article provided by the registration terminal 100, and if the comparison result is different, the article obtained by the verification request terminal 200 is different from the article provided by the registration terminal 100, the server 300 sends the comparison result to the verification request terminal 200 after completing the comparison and stores the comparison result in the database of the server 300, the comparison result includes the comparison time, the IP address of the verification request terminal 200, the equipment information of the verification request terminal 200 and the like in addition to the article identity information comparison, and the circulation state of the article can be recorded by recording the comparison result.
According to the article identification system, the article registration method, and the article verification method provided in the embodiments of fig. 1 to fig. 7, an embodiment of the present invention further provides an article identification method, which may be an anti-counterfeit method for articles such as bottles or bags, an anti-unpacking method for express articles, or a tracing method for article information, and the following description is made in detail with reference to fig. 8. Fig. 8 is a flowchart illustrating an article identification method according to an embodiment of the present invention. The method comprises the following main steps:
s301, storing the encrypted first natural texture information and the encrypted first additional information in an article registration database, wherein the first natural texture information comprises coordinates, colors and shapes of randomly distributed patterns.
Specifically, the item registration database is a database of the server 300, and is used for registering item identity information. The first natural texture information and the first additional information are identity information obtained by the registration terminal 100 from an article, and are named as first natural texture information and first additional information for the convenience of distinguishing from the article identity information obtained by the authentication request terminal 200, and the identification process and the encryption process thereof are described in the above embodiments and are not described herein again.
Furthermore, the first natural texture information can also be at least one of the area or the density of the randomly distributed pattern, and the accuracy of the identity information can be further increased and the identity identification safety can be improved through comparison of multiple dimensions.
The registration terminal 100 obtains the first natural texture information and then encrypts the first natural texture information to obtain an encrypted data string, wherein the encryption algorithm may be an RSA algorithm or a hash algorithm, and the encryption factor may be additional information such as a manufacturer code or/and a product code or/and a place of manufacture code. What encryption factor is used is set according to the user at the side of the registration terminal 100 when the identification area image 10 is set, and the security of the first natural texture information in the transmission and storage process is greatly improved because the encryption factor is customized by the registration terminal 100.
The first additional information and the first natural texture information are sent to the database of the server 300 together, so that an index is established according to the first additional information, and subsequent data searching and comparison are facilitated. Alternatively, when the server 300 is provided by the registered terminal 100, the registered terminal 100 may also be the server 300, so that the registered terminal 100 does not need to transmit data after obtaining the first natural texture information and the first additional information, and directly stores the data in the database. Preferably, the first additional information can also be encrypted, so that the security of data transmission and storage is improved.
Preferably, in order to prevent erroneous judgment due to non-human factors, the registration terminal 100 may further have a redundancy correction capability when recognizing the identification area image 10, and a tolerance range is set for a result obtained during image recognition, so that the false rejection rate can reach an acceptable range.
S302, receiving the encrypted second natural texture information and the second additional information from the authentication request end, where the second natural texture information includes coordinates, colors, and shapes of the randomly distributed pattern.
Specifically, the verification request terminal 200 is a user-side terminal that needs to identify the identity of an article, the process of acquiring the identification area image 10 on the article and identifying the natural texture information and the additional information by the verification request terminal 200 after obtaining the article is the same as that of the registration terminal 100, the natural texture information and the additional information obtained by the verification request terminal 200 may be referred to as second natural texture information and second additional information to be distinguished from the natural texture information and the additional information stored in the database by the registration terminal 100, the definition of the second natural texture information and the second additional information is the same as that of the natural texture information and the additional information in the above embodiment, and the identification of the second natural texture information and the second additional information may also have a redundant correction step, which is not described herein again.
The authentication requesting terminal 200 encrypts the obtained second natural texture information in the same way, the encryption algorithm may be the same as or different from that of the registration terminal 100, the encryption factor may be additional information of the identification area image 10, the additional information of the encryption factor is set by the registration terminal user when setting the identification area image 10, and preferably, the second additional information may also be encrypted. The authentication request terminal 200 transmits the encrypted second natural texture information and second additional information to the server 300.
S303, searching the first additional information according to the second additional information so as to extract corresponding first natural texture information, decrypting the second natural texture information and the first natural texture information respectively and then comparing the second natural texture information and the first natural texture information, wherein the comparison comprises comparing the coordinates, the colors and the shapes of the randomly distributed patterns.
Specifically, since the first additional information stored in the database by the registration terminal 100 corresponds to the first natural texture information, and the second natural texture information sent to the server 300 by the verification request terminal 200 corresponds to the second additional information, the server 300 may search the first additional information according to the second additional information, send a result that the corresponding data is not searched to the verification request terminal 200 if the corresponding first additional information is not searched according to the second additional information, after receiving the result that the first additional information is not searched, the verification request terminal 200 may directly determine that the verified item is not an item provided by the registration terminal 100, and may also check whether the image 10 of the identification area scanned by itself is correct, and then perform image acquisition and identification again and send data to the server 300.
If the server 300 finds the corresponding first additional information according to the second additional information, the corresponding first natural texture information may be extracted according to the first additional information, and then the first natural texture information and the second natural texture information are decrypted and compared, respectively. By creating an index of the additional information and the natural texture information, the data comparison capacity can be reduced, and the operation speed of the server 300 can be increased. If the first natural texture information is successfully compared with the second natural texture information, the article requested to be verified by the verification request terminal 200 is the article provided by the registration terminal 100, that is, the article identity is true; if the comparison between the first natural texture information and the second natural texture information is unsuccessful, the article requested to be verified by the verification request terminal 200 is not the article provided by the registration terminal 100, i.e. the article identity is false. The server 300 may store the comparison result in a database record, and the comparison result record may further include the comparison time, the IP address of the verification request terminal 20, the device information of the verification request terminal 200, and the like. The circulation state of the article can be searched by recording the comparison result information.
S304, sending the comparison result to the verification request terminal.
The server 300 sends the comparison result of the first natural texture information and the second natural texture information to the verification request terminal 200, where the sent comparison result includes the identity of the verified item, the comparison time, the IP address and the device information of the verification request terminal 200, and the like.
The following respectively combines fig. 9 and fig. 11 to explain in detail the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in two specific embodiments of liquor anti-counterfeiting and express anti-unpacking.
Referring to fig. 9, fig. 9 is a schematic flow chart of the anti-counterfeiting method for white spirit according to this embodiment, before the method is executed, an identification area image 10 is further included in the white spirit bottle body, and as shown in fig. 10, the step of setting the identification area image 10 may include:
1. the white spirit producer prepares the adhesive sticker adhesive film and the POF heat-shrinkable packaging film with naturally dispersed red fluorescent powder particles and green fluorescent powder particles, wherein the adhesive sticker adhesive film and the POF heat-shrinkable packaging film can be prepared by the white spirit producer and can also be purchased from other places by the white spirit producer.
2. The method comprises the steps of printing locators on a self-adhesive film and a POF (pre-oriented film) heat-shrinkable packaging film to respectively define identification area images 10, printing product label content on the self-adhesive film, printing an additional information area in a two-dimensional code mode according to the locators after the locators are printed, wherein the additional information of the additional information area is a product LOT (load index) number and a product series code, and is used for specifying an encryption factor. The background color printed in the natural texture area is black, and the recognition effect of the black background is better. The number of identification area images 10 on each film may be 1 or more.
3. Sticking the adhesive sticker film printed with the trademark and the identification area image 10 on the wall of the white spirit bottle, thermally shrinking the POF thermal shrinkage packaging film on the mouth of the white spirit bottle, ensuring that the identification area image 10 stretches across the bottle cap and the bottle mouth, completing the setting of the identification area image 10, and finishing the white spirit bottle as shown in figure 10.
After the recognition area image 10 is set on the white spirit bottle body, the identity of the white spirit is defined, and then the anti-counterfeiting method can be used for anti-counterfeiting, in this embodiment, the registration terminal 100 is a white spirit producer, the server 300 is a third-party server, and the verification request terminal 200 is a white spirit user.
The computer with a camera and running software for the production company collects the identification area image 10 of the white spirit bottle body, and for the convenience of distinguishing, the identification area image 10 collected by the manufacturer is called a first identification area image (step S401), and the first identification area image comprises the identification area image 10 positioned on the bottle wall and the identification area image 10 positioned on the bottle opening. The manufacturer terminal obtains the first identification area image and then identifies the first identification area image to obtain first natural texture information and first additional information (step S402), wherein the first natural texture information comprises coordinates, RGB values and shapes of fluorescent powder particles in the identification area image 10 of the bottle wall and the bottle mouth, and the first additional information is information set when the identification area image 10 is set.
The manufacturer terminal obtains the first encrypted data after encryption by performing encryption algorithm operation on the identified first natural texture information by using a preset encryption factor (step S403). The first encrypted data and the first additional information are sent to the third-party server by the producer terminal, and the first encrypted data and the first additional information are stored in a database located in the server by the third-party server (step S404), so that the white spirit producer completes registration of white spirit identity information, and the white spirit can enter the market.
Any user who purchases the white spirit in the white spirit market can initiate a process of verifying the authenticity of the white spirit. The user terminal obtains the white spirit body identification area image 10 by using a mobile phone with an app running function, the identification area image 10 obtained by the user terminal is called a second identification area image for distinguishing conveniently (step S405), the user terminal obtains the second identification area image and then identifies the second identification area image to obtain second natural texture information and second additional information (step S406), the second natural texture information comprises coordinates, RGB values and shapes of fluorescent powder particles in the identification area image 10 of the bottle wall and the bottle mouth, and the second additional information is information set when the identification area image 10 is set.
The user terminal obtains the encrypted second encrypted data by performing encryption algorithm operation on the identified second natural texture information by using a preset encryption factor (step S407). The user terminal sends the second encrypted data and the second additional information to a third-party server (step S408), the third-party server searches for corresponding first additional information according to the second additional information (step S409), if the third-party server does not find the corresponding first additional information, the third-party server can send information that the corresponding data is not found to the user terminal, the user terminal can reacquire the second identification area image to identify and send the encrypted data after receiving the information that the server does not find the corresponding first additional information, and can also obtain a conclusion that the liquor is not in the database, so that the liquor is false. If the third-party server finds the corresponding first additional information, the corresponding first encrypted data is extracted according to the first additional information (step S409). And the third party server decrypts and compares the first encrypted data with the second encrypted data respectively (step S410), if the first encrypted data and the second encrypted data are successfully compared, the liquor is true, and if the first encrypted data and the second encrypted data are not successfully compared, the liquor is false. The third-party server sends the comparison result to the user terminal (step S411), and the user knows the authenticity of the white spirit.
The white spirit anti-counterfeiting method can effectively distinguish the authenticity of the white spirit so as to prevent counterfeit wine victims, meanwhile, as the multicolor fluorescent powder particles pasted with the films on the white spirit bottles are randomly formed, the definition of the images in the identification area is random, even if white spirit production staff do not know the coordinates, colors and shapes of the fluorescent powder particles when the images in the identification area are not scanned, the staff cannot make a counterfeit identity label.
Based on the same principle, the article identification method may also be used for express anti-unpacking, referring to fig. 11, fig. 11 is a schematic flow chart of the express anti-unpacking method of this embodiment, before executing the method, the method further includes setting an identification area image 10 on an express package, as shown in fig. 12 to fig. 13, the step of setting the identification area image 10 may include:
1. the express company prepares the adhesive sticker adhesive film with naturally dispersed red fluorescent powder particles and green fluorescent powder particles, and the adhesive sticker adhesive film can be produced by the express company and can also be purchased.
2. When receiving express, the courier enters necessary information such as the time of receipt, the code of the courier, etc., and prints the locator 16 on the self-adhesive sticker to define the identification area image 10, and prints an additional information area with the necessary information according to the locator 16, and prints the background color of the natural texture area 12 as black.
3. And finally, the self-adhesive film is stuck to the sealing position of the express package, and the sealing position is sealed by using a transparent adhesive tape, in the embodiment of the invention, two identification area images 10 arranged at the sealing position of the express package can be provided, as shown in fig. 12.
After the identification area image 10 is set on the express package, the identity of the express package is defined, and then the express package anti-unpacking method can be adopted to prevent others from unpacking and replacing articles in the express package in the transportation process. In this embodiment, the registration terminal 100 is an express company, the server 300 is a third-party server, and the verification request terminal 200 is an express recipient.
The express company collects the identification area image 10 of the express package seal by using the image collecting device, and for the convenience of distinguishing, the identification area image 10 collected by the express company is called a first identification area image (step S501). The image acquisition device can be a hand-held image scanning device with integrated software and hardware, such as a mobile phone running an app or a browser, or a dedicated image acquisition device running software. In this embodiment, there are two first identification area images. The express company terminal obtains the first identification area image and then identifies the first identification area image to obtain first natural texture information and first additional information (step S502), wherein the first natural texture information includes coordinates, RGB values and shapes of phosphor particles in the first identification area image, and the first additional information is information set when the identification area image 10 is set.
The express company terminal calculates the identified first natural texture information by an encryption algorithm by using a preset encryption factor to obtain encrypted first encrypted data (step S503). The terminal of the express company sends the first encrypted data and the first additional information to the third-party server, the third-party server stores the first encrypted data and the first additional information in a database located at the server (step S504), and stores the encrypted code string in the database together with the additional information, so that an index can be established for fast searching of the subsequent data. Therefore, the express company completes registration of the identity information of the express package, and the express enters a transportation state.
When the express reaches a receiver, the receiver firstly confirms whether the self-adhesive film and the identification area image 10 are complete, if the self-adhesive film or the identification area image 10 is incomplete, the receiver refuses to receive the express, and the self-adhesive film and the identification area image 10 are complete, and then the following steps are carried out.
An express recipient obtains an identification area image 10 of an express package seal by using a mobile phone running app or a browser, in order to facilitate distinguishing, the identification area image 10 obtained by an express recipient terminal is called a second identification area image (step S505), the express recipient terminal obtains the second identification area image and then identifies the second identification area image to obtain second natural texture information and second additional information (step S506), the second natural texture information comprises coordinates, RGB values and shapes of fluorescent powder particles in all identification area images 10 of the express package seal, and the second additional information is information set when the identification area image 10 is set.
And the express recipient terminal calculates the identified second natural texture information by an encryption algorithm by adopting a preset encryption factor to obtain encrypted second encrypted data (step S507). The express recipient terminal sends the second encrypted data and the second additional information to a third-party server (step S508), the third-party server searches for corresponding first additional information according to the second additional information (step S509), if the third-party server does not find the corresponding first additional information, the third-party server can send information that the corresponding data is not found to the express recipient terminal, and after receiving the information that the corresponding first additional information is not found by the server, the express recipient terminal can obtain the second identification area image again for identifying and sending the encrypted data, and can also obtain a conclusion that the express is not in the database, so that the express recipient drops the package. If the third-party server finds the corresponding first additional information, the corresponding first encrypted data is extracted according to the first additional information (step S509). The third-party server decrypts and compares the first encrypted data and the second encrypted data respectively (step S510), if the first encrypted data and the second encrypted data are successfully compared, the express is not taken apart by a person, and if the first encrypted data and the second encrypted data are not successfully compared, the express is taken apart by the person. The third-party server sends the comparison result to the express recipient terminal (step S511), so that the express recipient can know the conclusion whether the express is detached by the person, and further judge whether to receive the express according to the comparison result.
The express bag unpacking preventing method can effectively prevent express bags from being unpacked by people in the transportation process, and the identification area image 10 is not suitable for being counterfeited and has good unpacking preventing effect because the coordinates, the colors and the shapes of the fluorescent powder particles on the identification area image 10 have uniqueness, and the counterfeiting difficulty and the cost of the coordinates, the colors and the shapes of the fluorescent powder particles are high.
