Description
Technical Field
The invention relates to the field of anti-counterfeiting identification and two-dimensional codes, in particular to an article identification method, an article identification method and an article identification system based on the two-dimensional codes.
Background
The two-dimensional code records data symbol information in a two-dimensional direction by using a specific geometric figure according to a certain rule; in coding, the concept of "0" and "1" bit stream which forms the internal logic basis of computer is used, several geometric forms correspondent to binary system are used to represent literal numerical information, and can be automatically read by means of image input equipment or photoelectric scanning equipment so as to implement automatic information processing: it has some commonality of barcode technology: each code system has its specific character set; each character occupies a certain width; has certain checking function and the like. Two-dimensional codes are a more advanced bar code format than one-dimensional codes. One-dimensional codes can only express information in one direction (generally, the horizontal direction), while two-dimensional codes can store information in both the horizontal and vertical directions. The one-dimensional code only consists of numbers and letters, and the two-dimensional code can store information such as Chinese characters, numbers, pictures and the like, so that the application field of the two-dimensional code is much wider. The two-dimensional bar code technology is a high-tech means for data anti-counterfeiting, carrying and transferring which is popular internationally in recent years. The method has the characteristics of large storage capacity, high confidentiality, high traceability, strong damage resistance, high redundancy, low cost and the like.
A natural attribute is an abstract noun that is descriptive of the nature of the face, regularity, phenomenon, and characteristics of an object in nature. It is a part of the description that is not subject to change by human mind and adjustment. The attribute of the changed things is the category of social attributes. The encryption algorithm is to process the original plain text file or data according to a certain algorithm to make it an unreadable segment of code. The aim of protecting data from being stolen and read by an illegal person is achieved through an encryption algorithm, and the reverse process (the process of converting the coded information into the original data) of the process is decryption.
The existing anti-counterfeiting technology comprises telephone code anti-counterfeiting, short message anti-counterfeiting or anti-counterfeiting through a radio frequency tag and a two-dimensional code. The anti-counterfeiting modes such as telephone code anti-counterfeiting and short message anti-counterfeiting have the defect of inconvenient detection, namely, the anti-counterfeiting mode needs to be authenticated through telephone or short message access and the like during each authenticity detection. The radio frequency label is used for anti-counterfeiting, the anti-counterfeiting cost is high, and the problem of environmental pollution exists. The existing two-dimension code anti-counterfeiting technology causes a bad manufacturer to produce a fake product of a high-quality product because of low production cost of the two-dimension code, or pretends an overdue or inferior product or a second-hand product into an original product for sale, thereby greatly damaging the benefits of consumers and destroying the social harmony and stability.
Disclosure of Invention
The invention provides an article identification method, an article identification method and an article identification system based on two-dimensional codes, and aims to identify articles by combining selected article characteristic information and an encryption algorithm and increase anti-counterfeiting strength.
The technical scheme provided by the invention is as follows:
an article identification method based on two-dimensional codes comprises the following steps:
s100, inputting characteristic information of an article to be identified;
s200, generating a characteristic two-dimensional code according to the characteristic information by combining a preset generation rule;
s300, the generated characteristic two-dimensional codes are marked on the articles to be marked according to the one-to-one correspondence relationship.
In the invention, the characteristic information of the article to be identified is obtained by the two-dimensional code generating device, then the characteristic information is generated into the characteristic two-dimensional code according to the preset generating rule, and the generated two-dimensional code identifies the article to be identified according to the one-to-one corresponding relation. Therefore, repeated identification or missing identification can be avoided, and meanwhile, identification is carried out in a one-to-one correspondence mode, and the identification can be used as a unique identification code of an article and used for distinguishing uniqueness and uniqueness of the article.
Further, the step S100 includes, before the step, the steps of:
s010 presets the generating rule and stores the preset generating rule;
wherein the generation rule comprises a composition rule and/or an encryption algorithm;
the composition rule comprises the length of the characteristic two-dimensional code and/or the position of each byte of the characteristic two-dimensional code and/or the meaning of each byte; the encryption algorithm includes any one or more of internationally and/or domestically recognized encryption algorithms.
In the invention, the articles are not particularly specified to a certain object or a class of objects, but have more general meanings, including all commodities or electronic data and products of a virtual world in work and life of clothes, food, live, and the like of people. The encryption algorithm may be an SM series algorithm issued by the national crypto authority, or an internationally recognized algorithm such as RSA and AES. In order to ensure the security of the item identification number, the encryption algorithm used is not limited to a single key or a public key mechanism or a hash function according to the actual requirements (such as security requirements, convenience of parsing, etc.).
Further, the step S200 further includes the steps of:
s210, the characteristic information is obtained, and the characteristic information comprises natural attribute information and/or social attribute information of the article to be identified.
S220, generating a characteristic information character string according to the characteristic information and the preset generation rule;
s230, judging whether the length of the generated characteristic information character string is larger than the length of a preset two-dimensional code; if yes, go to step S240, otherwise go to step S250 directly;
s240, deleting characters of the characteristic information character string according to a preset deletion method; until the length of the characteristic information character string is less than or equal to the length of the preset two-dimensional code;
s250, storing the characteristic information character string; and/or the presence of a gas in the gas,
s260, encrypting the characteristic information character string according to the preset encryption algorithm;
and S270, generating the characteristic two-dimensional code from the characteristic information character string according to the generation rule and storing the characteristic two-dimensional code.
The method can acquire one or more kinds of characteristic information of an article to be identified, generate a characteristic information character string according to a preset generation rule by using the acquired characteristic information, judge whether the length of the generated characteristic information character string is larger than the length of a preset two-dimensional code or not because the length of a character set of the two-dimensional code is limited after the characteristic information character string is generated, store the characteristic information character string if the length of the character set of the two-dimensional code is smaller than or equal to the length of the preset two-dimensional code, and generate the characteristic two-dimensional code according to the generation rule by using the characteristic information character string. If the number of the characters is larger than the preset number of the characters, deleting the characters of the characteristic information character string according to a preset deleting method; and storing the deleted feature information character string until the length of the feature information character string is less than or equal to the length of the preset two-dimensional code, and then generating the feature information character string into the feature two-dimensional code according to the generation rule by using the deleted feature information character string. The deleting method can delete characters with large capacity in sequence from large to small according to the character capacity (or delete characters with small capacity in sequence from small to large according to the character capacity) according to the program script; according to the sequence of the character strings, the high order is deleted from the low order (or the low order is deleted from the high order); characters can be deleted according to the importance degree of the characteristic information, for example, the apple brand, the origin and the model of the apple mobile phone are important information, and the weight and the raw materials are not important information. Of course, this is just an assumption and not the real case. The nature and social attributes of an article include, but are not limited to, the name of the raw materials that make up the article, the place of manufacture, the manufacturer, the lot, the date of manufacture, the shape, the color, the weight, the odor, and the like.
In the invention, the characteristic two-dimensional code can be generated only according to the characteristic information, and can also be generated by combining the characteristic information with an encryption algorithm, and the security of the latter is higher, so that the security of the anti-counterfeiting technology can be greatly improved, and the rights and interests of original producers and consumers can be guaranteed.
Further, the step S300 includes the steps of:
s310, judging whether the characteristic two-dimensional code is used or not according to the characteristic two-dimensional code; if yes, go to step S320, otherwise go to step S330;
s320, storing the characteristic two-dimensional code into the used two-dimensional code database; and returns to step S200;
s330, the generated characteristic two-dimensional code is marked on the article to be marked according to the one-to-one correspondence relationship.
In the invention, when the characteristic two-dimensional codes are generated in batch, repeated identification or identification omission can occur, and the used two-dimensional codes are classified into the used two-dimensional code database through judgment, so that the one-to-one corresponding identification efficiency can be improved, and meanwhile, the characteristic two-dimensional codes on the articles are used as the unique identification codes of the articles to distinguish the uniqueness and uniqueness of the articles.
The invention also provides an article identification method based on the two-dimensional code, which is characterized by comprising the following steps:
s410, scanning a two-dimensional code on an object to be scanned, judging whether the two-dimensional code is a characteristic two-dimensional code, and if so, executing a step S420; otherwise, go to step S460;
s420, analyzing the acquired characteristic two-dimensional code according to a preset generation rule to obtain analyzed article information;
s460, the failure of identifying the object to be scanned is output, and the scanning identification process is quitted.
In the invention, the article identification method is a reverse process of the identification method, and the generation rules of the two methods are consistent, namely the composition rule and the encryption algorithm are consistent, so that when a user identifies an article by using the article characteristic two-dimensional code, performs quality inspection or after the user is put into the market, and when the user needs to identify the article, the characteristic two-dimensional code on the article is scanned, and then the acquired characteristic two-dimensional code is analyzed according to the generation rule to obtain analyzed article information, for example, the scanned article characteristic information can be relatively simple.
If the scanning device cannot identify the two-dimensional code, but can identify the origin of the two-dimensional code, for example, the scanning function of the browser cannot scan the two-dimensional code of the WeChat but can jump to a WeChat webpage, and the user scans and acquires the information of the two-dimensional code after logging in.
Further, after the step S420 and before the step S460, the method further includes the steps of:
s430, judging whether the analyzed article information is consistent with article information contained in the characteristic two-dimensional code database, if so, executing a step S440; otherwise, go to step S450;
s440, outputting that the scanned article is consistent with preset article information;
s450, outputting that the scanned article is inconsistent with the preset article information.
In the invention, the analyzed article information obtained based on the scanned characteristic two-dimensional code is judged with the article characteristic information of the stored characteristic two-dimensional code, and whether the scanned article is consistent with the article information in the two-dimensional code database or not can be known after the judgment result is obtained. For example, if we scan the two-dimensional code of the apple on the computer and do not connect the network to access the official database, we can only obtain that the computer is the apple computer, but cannot know whether the apple computer is a genuine product, and it is likely to be a high-imitation product. The invention can greatly improve the security of the anti-counterfeiting technology and ensure the rights and interests of original producers and consumers.

Therefore, repeated identification or missing identification can be avoided, and meanwhile, identification is carried out in a one-to-one correspondence mode, and the identification can be used as a unique identification code of an article and used for distinguishing uniqueness and uniqueness of the article.

In order to ensure the security of the item identification number, the encryption algorithm used is not limited to a single key or a public key mechanism or a hash function according to the actual requirements (such as security requirements, convenience of parsing, etc.).

Specifically, in this embodiment, the generation rule includes a composition rule; the composition rule comprises setting the length of the characteristic two-dimensional code, and/or the position of each byte of the characteristic two-dimensional code, and/or the meaning of each byte.

In this embodiment, one or more kinds of feature information of an article to be identified may be acquired, the acquired feature information is generated into a feature information character string according to a preset generation rule, after the feature information character string is generated, since the length of the character set of the two-dimensional code is limited, it is further necessary to determine whether the length of the generated feature information character string is greater than a preset length of the two-dimensional code, if the length is less than or equal to the preset length of the two-dimensional code, the feature information character string is stored, and then the feature two-dimensional code is generated according to the generation rule according to the feature information character string.

Of course, this is just an assumption and not the real case. The nature and social attributes of an article include, but are not limited to, the name of the raw materials that make up the article, the place of manufacture, the manufacturer, the lot, the date of manufacture, the shape, the color, the weight, the odor, and the like.

s260, encrypting the characteristic information character string according to the preset encryption algorithm.
Specifically, in this embodiment, the encryption algorithm includes any one or more of internationally and/or domestically recognized encryption algorithms. The encryption algorithm may be an SM series algorithm issued by the national crypto authority, or an internationally recognized algorithm such as RSA and AES.

The security of the anti-counterfeiting technology can be greatly improved, and the rights and interests of original producers and consumers are guaranteed. By means of the internationally or domestically approved encryption algorithm, various natural or social attributes of the articles with typical meanings are used as encryption elements to form the two-dimensional code.

s420, analyzing the acquired characteristic two-dimensional code according to a preset generation rule to obtain analyzed article information;
s460, the failure of identifying the object to be scanned is output, and the scanning identification process is quitted.
Specifically, in this embodiment, the article identification method is an inverse process of the identification method, and the generation rules of the two methods should be consistent, that is, the composition rule and the encryption algorithm are consistent, so that when a user identifies an article after using the article characteristic two-dimensional code for identification, performs quality inspection, or after putting into the market, and the user needs to identify the article, the characteristic two-dimensional code on the article is scanned, and then the obtained characteristic two-dimensional code is analyzed according to the generation rule to obtain analyzed article information, for example, the scanned analyzed article information can obtain relatively simple article characteristic information.
If the scanning device cannot identify the two-dimensional code, but can identify the exit of the two-dimensional code, for example, the scanning function of the browser cannot scan the two-dimensional code of the WeChat but can jump to a WeChat webpage, and the user scans to obtain the information of the two-dimensional code after logging in.

The length of the two-dimensional code depends on the parsing efficiency of the code scanning device, wherein one two-dimensional code can accommodate as many as 1850 capital letters, 2710 digits, 1108 bytes, or more than 500 Chinese characters, but these indexes are greatly improved with the progress of the code scanning device.
For example: the two-dimensional code length is 256 bits, and is divided into two parts: the manufacturer self-defining and the signature are formed. The manufacturer defined 128bit is divided into:
1-8 bit: province codes are divided according to administrative regions;
9-12 bits: a two-dimensional code version code; 16 versions
13-20 bits: production plant code: 256 manuids;
21-36 bits: and (3) commodity code: commodity code, 65536
37-44 bits: product brand representation, 256 brands;
45-48: key version information; 16, the number of the channels is 16;

53-76 bits: manufacturing Time, utc Time format (BD Time), accurate to seconds; time origin: 2015-01-0100: 00: 00; (136 years data can be recorded)
77-84: batch information, etc., 256 batches;
and finally, 85-128 bits: the serial number is a two-dimensional code serial number (Sequence No.), and the serial number is unique to the same manufacturer ID identification;
129-256 bits: the first 128 bits are intercepted and encrypted by the root key, and the SM4 algorithm is adopted.
