Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide an authentication method, device and medium for the production date of an article so as to improve the authenticity of the production date of the article.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
When various types of articles are produced, information such as production date and shelf life of the articles is generally required to be marked, especially for some food types. However, since a part of the surface of the article has a natural or processed disordered texture, such an article is called a textured article, and related information such as a production date cannot be engraved on the textured article body due to the texture of the surface, and if the related information is marked on an outer package, the production date is easily forged by a lawbreaker replacing the package. Therefore, the texture features of the textured objects can be extracted and stored in the cloud. However, in the case that a lawbreaker does not own a corresponding textured article, the lawbreaker may obtain the related information of the textured article by simulating the texture features, so as to counterfeit the textured article, which may cause a serious food safety accident.
In order to solve the technical problem, the present application provides an article production date authentication method, which is applied to a registration terminal, and the present application embodiment records the textured article by scanning the texture of the textured article, because the texture of different textured articles is basically different, and the difference can be used to distinguish a plurality of textured articles in the same class. After the texture features are extracted, the texture features are encrypted, so that the texture objects counterfeited by lawbreakers can be avoided. In the complete solution of the present application, the registration terminal, the query terminal, and the cloud terminal are usually included, but not limited to the solution including three terminals, the registration terminal may be a rechargeable or plug-in device, and at least includes a device such as a camera for scanning textured objects, and a device such as a computer for facilitating registration operation of a registrant, in addition, the registration terminal is generally fixed at a position, and continuously places the textured objects under the camera for scanning, so a light source may be added at a corresponding position, so that the camera can clearly scan textures, the types, installation positions, and numbers of the devices such as the camera, the computer, and the light source in the registration terminal are not limited, and in practical application, the data need to be stored after the texture is scanned by the registration terminal, and the data can be stored in the database of the registration terminal itself, but the database capacity of the registration terminal itself is limited, so that a large amount of data can be stored in the cloud terminal, and the query terminal directly queries in the cloud terminal. The inquiry terminal also needs a device such as a camera to scan the textured objects to be inquired, but the inquiry terminal is more flexible than the registration terminal, the requirement on the precision of the device is generally lower than that of the registration terminal, and mobile devices such as smart phones used in daily life can be used as the inquiry terminal. Fig. 1 is a flowchart of an authentication method applied to a registration terminal for an article production date according to an embodiment of the present application; as shown in fig. 1, the method comprises the steps of:
s10: and acquiring related information of the textured article.
The textured articles in the embodiment of the application include but are not limited to fresh articles such as cut noodles, pu' er tea cakes and salmon, the registration terminal needs to acquire the relevant information of the textured articles, but the acquisition mode is not limited, and generally, a registrant can acquire the relevant information of the textured articles in advance when registering the textured articles in batches. The quantity and type of the related information are not limited, and may include the production date of the textured article, the corresponding unique number during production, the expiration date, the registration date, and the product type to which the textured article belongs, and may also include related information of a responsible person, and when various problems occur in the related textured article, the related responsible person may be directly found, where the responsible person may be a registered person responsible for registering the textured article, or a responsible person in the whole production process, and is not limited here.
S11: the registration terminal scans the textured article to extract the corresponding texture features.
The method comprises the following specific steps: scanning the object with the texture to obtain a texture picture; and (3) extracting corresponding texture Features in the texture picture by using a Gray-level Co-segmentation Matrix (GLCM) in combination with FAST corner detection (Features From estimated segmented Test). The texture features extracted by the gray level co-occurrence matrix can effectively identify different textures, but lack the utilization of global information, so that the corner template is generated by determining the position relationship between corners (Euclidean distance and orientation between corners) by combining FAST corner detection. The corner point template provided by the embodiment of the application can well describe the global information of the texture.
Fig. 2 is a schematic structural diagram of a registration terminal according to an embodiment of the present disclosure; as shown in fig. 2, the device comprises a camera 6 and a light source 5 in a registration terminal, and a texture object 4; it should be noted that the registration terminal only provides a partial structure, and in fact, a computer or other device used by the registrant during the registration also belongs to the registration terminal, and when the registrant performs batch registration, because the workload is large and the continuous scanning of the camera 6 does not meet the actual requirement, a trigger button is generally set, and the registrant can execute a registration program only by pressing the trigger button. In addition, the number and the positions of the cameras 6 and the light sources 5 in the figures are only one example provided in the embodiments of the present application, and do not limit other solutions provided in the present application. The distance between the camera 6 and the textured object 4 is generally proper within the range of 10-50cm, so that the textured object 4 can be conveniently put in and taken out, and the texture features can be clearly scanned.
S12: matching the texture features and the related information of the textured article.
Under normal conditions, each registration is performed on the same kind of textured articles, and a large number of textured articles need to be registered, and after acquiring texture features and related information, the registration terminal needs to match the texture features and the related information of the same textured article to obtain a corresponding relationship between the texture features and the related information.
S13: the registration terminal encrypts the texture features.
The encryption processing specifically comprises the following steps:
1. and obtaining a texture picture pixel matrix according to the texture characteristics.
2. And normalizing the gray level co-occurrence matrix and then superposing the normalized gray level co-occurrence matrix to the texture picture pixel matrix.
3. The corner points are marked to the texture picture pixel matrix.
4. Adding high frequency noise interference textures to the texture picture pixel matrix.
5. Adjacent rows and adjacent columns of the texture picture pixel matrix are swapped.
6. Transpose the texture picture pixel matrix.
7. And setting a corresponding password to the texture picture pixel matrix to obtain the encrypted texture characteristics.
Normalizing the gray level co-occurrence matrix to the size of the texture picture, superposing the gray level co-occurrence matrix to a pixel matrix of the texture picture, marking the corner points to the pixel matrix of the picture, and finally normalizing the three encrypted contents to one pixel matrix. And finally, adding high-frequency noise interference textures of a fixed template, exchanging rows and columns of adjacent matrixes, and transposing to obtain a final matrix. And compressing the matrix, setting a compressed password, and uploading the compressed password to the cloud so as to finish the encryption work. During actual application, the encryption processing can be completed at the registration terminal and the inquiry terminal, and the encryption processing can also be completed through the cloud after being uploaded to the cloud. By encrypting the characteristic information, a lawbreaker cannot acquire the related information of the textured article by simulating the texture characteristic under the condition that the corresponding textured article is not owned, so as to counterfeit textured articles, thereby avoiding serious food safety accidents. Only when the corresponding textured object is really owned, the texture feature can be obtained by scanning the texture, and the texture feature is encrypted. And then, acquiring related information from the cloud through the texture features after encryption processing.
S14: and storing the corresponding relation between the texture features after the encryption processing and the related information.
During specific implementation, the registration process can be fully automated, the registration program is set in advance, then the textured articles are regularly put in through the transmission belt, after the textured articles reach the designated position, the transmission belt can be paused for a few seconds, the camera is waited for scanning, after the texture features are extracted, the registration terminal automatically matches the related information input in advance, the corresponding relation between the texture features and the related information is stored, and the corresponding relation is stored, namely the texture features and the related information of the textured articles are stored. The location where the correspondence relationship is stored is not limited, and the location may be stored in a database of the registration terminal itself, but generally, the database capacity of the registration terminal itself is limited, so that a large amount of data may be stored in the cloud, and the query terminal obtains the texture features and then queries the corresponding relevant information in the cloud according to the correspondence relationship. Fig. 3 is a schematic structural diagram of an inquiry terminal according to an embodiment of the present application; the structure shown in fig. 3 is only one scheme in the present Application, and as shown in fig. 3, includes an inquiry terminal 2 and a textured article 4, where the inquiry terminal 2 is a smart phone, and collects texture features of the surface of the textured article 4 in an Application (APP) or applet manner, and invokes an article inquiry interface to inquire out related information of the production date, registration time, registered person, and the like of the textured article 4. As shown, the distance between the interrogation terminal 2 and the textured item 4 may also be in the range of 10-50 cm.

As shown in the figure, the method comprises a registration terminal 1, an inquiry terminal 2 and a cloud terminal 3, wherein a registrant inputs an account number and a password to log in the registration terminal, then places a textured article to be registered in a visual field range of a camera, performs photographing registration on the registration terminal 1, records the current time while the registration terminal 1 acquires an image, sends texture features acquired from the image to the cloud terminal 3, and stores information after the cloud terminal 3 encrypts the texture features. The query terminal 2 performs photographing query on the textured object to be queried, then sends the scanned and obtained texture features to the cloud end 3, the cloud end 3 also performs encryption processing on the texture features, then performs information extraction to match corresponding related information, and finally the cloud end 3 returns the extracted related information to the query terminal 2 so that the query terminal 2 can display the related information. The cloud 3 adopts a high-performance storage query system to support massive query to be carried out concurrently; in order to guarantee the usage experience, the response time of the registration interface and the inquiry interface should not exceed 20 milliseconds at the maximum. The encryption algorithm used by the registration interface and the query interface on the cloud 3 needs to ensure that the encryption results of different texture features are not repeated. According to the method provided by the embodiment of the application, when the surface of the textured article slightly changes due to various factors, namely the texture features are defective, the relevant information corresponding to the textured article can still be quickly and accurately inquired. In addition, the encryption process may be performed at the registration terminal 1 and the inquiry terminal 2.
