referring to fig. 1, fig. 1 is a flow chart of an anti-counterfeiting method for verifying authenticity of a commodity before purchase in the embodiment; the anti-counterfeiting method for verifying authenticity before purchasing the commodity in the embodiment comprises the following steps:
s1: an information carrier is generated from the initial information of the article. The initial information of the commodity is basic information of the commodity when the commodity leaves a factory, and the initial information comprises a commodity name, a production date, a production place, a manufacturer, a quality guarantee period, a sale area and the like; the information carrier is a carrier capable of storing information, being identified and having networking functions, and specifically, the information carrier can be a two-dimensional code or an RFID electronic tag, both of which have storage functions, and the two-dimensional code and the RFID electronic tag both have identifiable identity attributes and can be correspondingly associated to a network, for example, a cloud network; the corresponding information carrier is generated according to the initial information of the commodity, when the commodity leaves the factory, each commodity can be attached with an information carrier as a mark for identification and anti-counterfeiting, for example, a two-dimensional code or an RFID electronic tag is arranged on the commodity or a package of the commodity, and the factory information of the purchased commodity can be obtained by reading the commodity information stored in the information carrier from the outside.
S2: the initial information in the information carrier is stored in a database. The database can be specifically a cloud big data platform and a cloud database, initial information in an information carrier is stored in the database, namely the information carrier, the cloud big data platform and the cloud database form an association relation, the initial information is stored in the database, anti-counterfeiting data are established based on the initial information, and subsequent anti-counterfeiting data are stored in the database as identification points according to the initial information, wherein the cloud database is used for storing information content, and the cloud big data platform is used for processing data, such as Ariicloud, cloud platforms such as Baidu cloud and the like, or a specific anti-counterfeiting database processing platform; specifically, the association between the information carrier and the database can be realized through third-party software, for example, an APP installed on a smart phone, a user scans and identifies the information carrier through the smart phone, and establishes an association with a cloud database through the APP, so as to complete data connection, initial information storage, initial information identification matching, data interaction and the like between the information carrier and the database, in addition, the connection between the information carrier and the database can also be realized through an intelligent terminal with an identification function, and the cloud big data platform and the cloud database can complete data interaction with the smart phone or the intelligent terminal through wireless signals, such as 4G network signals, so that the association between the information carrier and the database is realized through a wireless network; after the information carrier is associated with the database and initial information is stored in the database, when a user scans and identifies the information carrier on the commodity through the smart phone, the information carrier can be associated with the database, and the initial information of the commodity is called and displayed on third-party software; the anti-counterfeiting method for verifying authenticity before purchasing the commodity in the embodiment is based on the identification of the information carrier and further verifies the data information content stored in the associated data to judge authenticity of the commodity.
S3: and judging whether the information carrier meets the first precondition of the preconditions, if not, outputting the information carrier to be abnormal, and if so, executing the next step. The precondition is to judge initial information in the information carrier and the information carrier respectively, and comprises a first precondition and a second precondition, wherein the first precondition is to judge the attribute of the information carrier, and the first precondition comprises whether the attribute of the information carrier meets a national standard and whether the information carrier is associated with a database, wherein the national standard is different according to different information carriers, for example, two-dimensional codes and RFID tags have different national standards respectively.
In this embodiment, the information carrier abnormality specifically includes the following cases: the information carrier is not put in storage, i.e. the information carrier is not associated to the database; the information carrier has high risk, which indicates that the commodity has risk, namely the commodity is a counterfeit commodity or an expired product, and both of the commodity and the expired product have high risk; the information carrier is not authenticated, the article may be problematic at the time of authentication, or the article is genuine but is not sold in the specified sales area.
S4: and judging whether the initial information in the information carrier meets a second precondition in preconditions, if not, outputting the information carrier to be abnormal, and if so, storing the judgment processes and results of the first precondition and the second precondition of the information carrier into a database. The second precondition is specifically to determine the initial information content stored in the information carrier, for example, the verification period of the information carrier is defined as the time period from the generation time of the information carrier to the current time when the information carrier is verified, and if the verification period is longer than the shelf life of the commodity, the commodity is an expired commodity.
The judgment process and result of the first precondition and the second precondition stored in the database are used for increasing the anti-counterfeiting data of the information carrier, specifically, after the judgment process and result of the first precondition and the second precondition are stored in the initial information of the information carrier in the database, the judgment process and result are used as the anti-counterfeiting trace information, and when the information carrier is verified next time, the information carrier is proved to be real only if the judgment process and result of the corresponding first precondition and the second precondition are required. In addition, if the information carrier is in an abnormal state, when the judgment is carried out next time, when the third-party software inquires the result of the abnormal state in the database and the judgment processes of the first precondition and the second precondition stored in the database correspond to the result, the information carrier can be directly output to be in the abnormal state, and the quick judgment is realized.
S5: and judging whether the information carrier accords with the geographical position condition in the trace tracking condition, if not, outputting that the information carrier is abnormal, and if so, storing the geographical position condition judgment process and result of the information carrier into a database. The trace tracking condition comprises a geographical position condition and a worker interference condition, wherein the geographical position condition of the information carrier judges the authenticity of the information carrier through the reasonability of the position and the position transformation of the information carrier; for example, whether the moving speed of the information carrier is greater than the preset moving speed of the information carrier, whether the information carrier is located in a specified sales area, and the like, wherein the moving speed of the information carrier is the moving speed when the commodity is verified, the preset moving speed of the information carrier is the reasonable speed of the commodity in the transportation process, and if the moving speed of the commodity exceeds the reasonable speed of the practical transportation means, the abnormal situation is caused, and the commodity has the risk of counterfeit and shoddy products; some goods have a specified sales area in which the goods are not sold, and there is a risk of counterfeit goods.
The judgment process and result of the geographical position condition stored in the database are also used for increasing the anti-counterfeiting data of the information carrier, and specifically, after the judgment process and result of the geographical position condition are stored in the initial information of the information carrier in the database, the judgment process and result are used as the anti-counterfeiting trace information, and when the information carrier is verified next time, the information carrier is proved to be real only if the judgment process and result of the corresponding geographical position condition are required. In addition, if the information carrier is in an abnormal state, when the judgment is carried out next time, when the third-party software inquires the result of the abnormal state in the database and the judgment process of the geographic position conditions stored in the database corresponds to the result, the information carrier can be directly output to be in the abnormal state, and the quick judgment is realized.
S6: judging whether the information carrier meets the manual interference condition in the trace tracking condition, if not, outputting the abnormal information carrier, if so, storing the judgment process and the result of the manual interference condition of the information carrier in a database; then step S7 is executed, and the output information carrier is normal. The manual intervention condition is defined by artificially setting parameters according to abnormal conditions which may occur in the actual selling process of the commodity, for example, the times of the information carrier being verified and the times of the position change of the information carrier are defined, wherein the times of the information carrier being verified are the times of the commodity being verified, in the actual selling process, one sold commodity is repeatedly sold without excessive verification, for example, the information carrier of one commodity is copied and then attached to other multiple fake commodities, when the fake commodities are sold, the information carrier is sold for multiple times, and similarly, one sold commodity is not sold for multiple times, and if the information carrier of one commodity is scanned and verified in multiple different regions, the unreasonable selling conditions of one commodity, namely, multiple selling conditions of one commodity and multiple selling conditions of one commodity are indicated.
The database stores the judgment process and result of the manual interference condition, and is also used for increasing the anti-counterfeiting data of the information carrier, specifically, after the judgment process and result of the manual interference condition are stored in the initial information of the information carrier in the database, the judgment process and result are used as the anti-counterfeiting trace information, and when the information carrier is verified next time, the information carrier is true only if the judgment process and result of the corresponding manual interference condition are required. In addition, if the information carrier is output in an abnormal state at this time, when the judgment is carried out next time, when the third-party software inquires the result of the abnormal state in the database and the judgment process of the manual interference condition stored in the database corresponds to the result, the information carrier can be directly output in the abnormal state, and the quick judgment is realized.
S7: after the judgment of the three conditions is completed, the output of the information carrier is normal, and the normal condition of the information carrier is that the information carrier passes the verification, so that the commodity is a genuine product or a genuine product.
Referring to fig. 1 and fig. 2 again, fig. 2 is a flowchart illustrating the process of determining the first precondition and the second precondition in this embodiment, and further, the determining whether the information carrier meets the first precondition and the second precondition in this embodiment includes the following sub-steps:
s31: judging whether the information carrier meets the national standard or not; if no, the output information carrier is in a high risk abnormal state, if yes, the next step is performed. In the step S31, if the information carrier is a two-dimensional code, it is determined whether the information carrier meets the national standard of the two-dimensional code of the national commodity, the standard number GB/T33993-; if the information carrier is an RFID label, whether the information carrier meets the national RFID standard is judged, the standard number GB/T29768-2013 is used, and the national standard is used as the judgment standard for whether the RFID label is a real RFID label. If the two-dimensional code or the RFID tag is false, it may be determined that the article is counterfeit, and in step S31, a high-risk abnormal state indicates that the article is counterfeit.
S32: and judging whether the information carrier is associated with the database, if not, outputting the abnormal state that the information carrier is not put in a database, and if so, executing the next step. When the information carrier is not associated to the database, even if the information carrier is real, a user cannot inquire initial information of the commodity through third-party software to judge whether the commodity is true or false, and at the moment, the output commodity is in an abnormal state without being put in storage; in actual production activities, when a genuine commodity leaves a factory, factory detection is a necessary step, namely, an information carrier needs to be associated with a database before the genuine commodity leaves the factory, and an abnormal state which is not stored at the moment indicates that the commodity does not pass through the detection step of the associated database and also indicates that the commodity has a risk of being a counterfeit product.
S33: judging whether the judgment process and result data of the first precondition and the second precondition are stored in the database, if not, outputting an abnormal state with high risk to the information carrier; if yes, the next step is executed. After the user realizes the association between the information carrier and the database through the third-party software, firstly, the third-party software can firstly inquire whether the judgment process and the corresponding result of the first precondition and the second precondition exist below the initial information stored in the database, because the judgment of the first precondition and the second precondition can be carried out when the commodity is detected in a factory even before circulation, the corresponding judgment process and result can be stored in the information carrier, and if the corresponding process and result are not detected, the commodity is a counterfeit product.
S34: and judging whether the verification period of the information carrier is less than the quality guarantee period of the commodity, if not, outputting the abnormal state of the information carrier with high risk, and if so, executing the next step. The user firstly inquires the historical data judged by the first precondition and the second precondition in the database, then the actual content of the initial information, namely the factory information of the commodity is used as comparison, specifically, when the user scans the information carrier, the current date and time of the scanned information carrier can be obtained, then the verification period is calculated according to the production date and time in the initial information, the verification period is compared with the quality guarantee period of the commodity in the initial information, if the verification period of the information carrier is greater than the quality guarantee period of the commodity, the commodity is proved to have passed the quality guarantee period, the commodity is an expired product, and the abnormal state with high risk of the commodity is output.
S35: the first precondition and the second precondition of the information carrier are stored in a database. And after the verification period of the verification information carrier is shorter than the quality guarantee period of the commodity, judging processes and results of the first precondition and the second precondition in the preconditions are stored in the database and used as anti-counterfeiting trace data, the anti-counterfeiting performance of the information carrier is increased again, and the subsequent verification processes and results are used as anti-counterfeiting data.
Referring to fig. 1 and fig. 3, fig. 3 is a flowchart illustrating a process of determining a geographical location condition in this embodiment, and further, the determining whether the information carrier meets the geographical location condition in this embodiment includes the following sub-steps:
s41: judging whether a judgment process and result data of the geographical position condition are stored in the database, if not, outputting an abnormal state with high risk of the information carrier; if yes, the next step is executed. After the precondition judgment of the information carrier is completed, a user can inquire whether the judgment process and the corresponding result of the geographical position condition exist under the initial information stored in the database through third-party software, the judgment process and the corresponding result are similar to the precondition, the geographical position condition can be judged when the commodity is detected in a factory before circulation, the corresponding judgment process and the corresponding result can be stored in the information carrier, and if the corresponding process and the corresponding result are not detected, the commodity is a counterfeit product.
S42: and judging whether the moving speed of the information carrier is greater than the preset moving speed of the information carrier, if so, outputting the abnormal state of the information carrier with high risk, and if not, executing the next step. In the process of selling and circulating commodities, the situation of rapid movement generally does not occur, when the situation that the same information carrier is verified and judged in a short time in two places far away, namely the appearance of counterfeit products, is reflected in the aspect of speed, namely the moving speed of the information carrier is greater than the preset moving speed, namely the limited moving speed, wherein the limited moving speed is the speed of a general transportation vehicle, the transportation vehicle is different according to different commodities, for example, the conventional speed of transportation by a truck does not exceed 80km/s, the conventional speed of transportation by a train does not exceed 400km/s, and when the moving speed of the information carrier exceeds the speed of the conventional transportation vehicle, the commodity is a counterfeit product.
S43: and judging whether the information carrier is located in the specified sale area, if not, outputting the information carrier to be in an abnormal state which is not verified, and if so, executing the next step. In actual commercial activities, most commodities have limited sales areas, for example, the sales areas are divided by countries or provinces, the commodities have fixed sales areas, and if the commodities appear in non-sales areas for sale, the commodities are counterfeit commodities, for example, the commodities limited to be sold in the uk, but appear in certain cities on the continents, so that the risk of counterfeit commodities is high.
S44: storing the judgment process and result of the geographical position condition of the information carrier into a database. The geographical position condition judgment process and the result of the information carrier are stored in a database and used as a new anti-counterfeiting judgment basis in the next commodity authenticity verification, the anti-counterfeiting performance of the information carrier is improved, and the subsequent verification process and the result are used as new anti-counterfeiting data every time, so that the anti-counterfeiting performance of the information carrier is continuously improved.
Referring to fig. 1 and 4, fig. 4 is a flowchart illustrating a process of determining an artificial interference condition in this embodiment, and further, determining whether an information carrier meets the artificial interference condition in this embodiment includes the following sub-steps:
s51: judging whether a judgment process and result data of the manual interference condition are stored in the database, if not, outputting an abnormal state with high risk of the information carrier; if yes, the next step is executed. After the geographical position condition of the information carrier is judged, a user can inquire whether a judgment process and a corresponding result of the artificial interference condition exist under the initial information stored in the database through third-party software, the judgment process and the corresponding result are similar to the geographical position condition, the artificial interference condition can be judged when factory detection is carried out before commodity circulation, the corresponding judgment process and the corresponding result are stored in the information carrier, and if the corresponding process and the corresponding result are not detected, the commodity is a counterfeit product.
S52: and judging whether the occurrence frequency of the interval distance smaller than the wheel base in the selling area of the information carrier is larger than the preset verification frequency of the information carrier, if so, outputting the information carrier to be in a high-risk abnormal state, and if not, executing the next step. Defining the selling area of the information carrier to be circular, the radius of the selling area to be the wheel base, the circle center of the selling area to be the axle center, and the distance between the position of the information carrier and the axle center when the information carrier is verified to be the spacing distance; when the occurrence times that the spacing distance is smaller than the wheel base is more, the commodity is verified for a plurality of times in the selling area, when the verification times of the information carrier exceed the preset verification times, namely the verification times that the information carrier is limited, the situation that one commodity is sold for a plurality of times in the selling area or is repeatedly sold is shown, according to the selling situation in the actual life, a fake product can be inferred, for example, some wines with outer packages, gift box commodities and the like can be obtained, one information carrier on the genuine commodity is copied to a plurality of fake commodities, and the situation that the information carrier is verified for a plurality of times in the selling area can occur.
S53: and judging whether the occurrence frequency that the spacing distance of the information carrier is greater than the wheel base is greater than the preset position conversion frequency of the information carrier, if so, outputting the information carrier to be in a high-risk abnormal state, and if not, executing the next step. When the occurrence times that the spacing distance is larger than the wheel base is more, the sales position of the commodity is changed for a plurality of times, namely the same commodity is sold in a plurality of places, according to the sales condition in real life, one commodity cannot be sold for a plurality of times, the sale of the commodity is repeatedly explained through the surplus explanation, namely the sale of a counterfeit product is inferred, for example, one household appliance commodity is sold in three places in front of and behind, even if the attached information carrier is real, the same household appliance commodity is sold for three times, so that the counterfeit commodity is explained, or the old machine is newly sold, and the conditions are high risk.
S54: and storing the manual interference condition judgment process and result of the information carrier into a database. The manual interference condition judgment process and the result of the information carrier are stored in the database and used as the judgment basis for the next commodity authenticity verification, the anti-counterfeiting performance of the information carrier is improved, the subsequent verification process and the result are used as new anti-counterfeiting data every time, and the anti-counterfeiting performance of the information carrier is continuously improved.
Referring to fig. 1 and fig. 2, in a further embodiment, the anti-counterfeiting method for verifying authenticity before purchasing a commodity in this embodiment may specifically complete the determination of the first precondition and the second precondition in the preconditions, the geographic position condition in the trace tracking condition, and the manual interference condition through an algorithm formula.
The information carrier is defined as x.
The result of the determination whether the information carrier meets the national standard is p1(x) And the judgment result of judging whether the information carrier is associated with the database is p2(x) The judgment result for judging whether the verification period of the information carrier is less than the quality guarantee period of the commodity is p3(x) (ii) a Defining the judgment result of the precondition as p (x); when x meets the national standard p1(x) The output is 1, otherwise, 0; when x is associated with a database p2(x) The output is 1, otherwise, 0; p when x is less than the shelf life of the commodity3(x) The output is 1, otherwise 0.
The precondition is determined by the formula
Where i ∈ {1, 2, 3}, pi(x) E {0, 1}, only if pi(x) When the output of (a) is 1, p (x) is 1, that is, when p is judged by the precondition, the output of p is 1i(x) If any of the outputs of (1) is 0, p (x) is 0, that is, it cannot be judged by the precondition.
Referring back to fig. 1 and 3, further, in the determination of the geographical position condition, the determination result of determining whether the moving speed of the information carrier is greater than the preset moving speed of the information carrier is g1(x) The result of the determination of whether the information carrier is located in the specified sales area is g2(x) And the judgment result of whether x meets the geographical position condition is g (x).
Geographical positionThe reasonability of the speed of the information carrier in the setting condition is judged by the formula
Wherein a and b are represented as any two places, s (x) when x is scanned and verifieda，xb) X is the distance between the places a and b when the places a and b are verified and judged, taAnd tbRespectively represents the time when x is verified and judged in a place and a place b, ta-tbDenoted as x is the time interval when both a and b are verified and judged,
in order to set the moving speed to a preset value,
represents the moving speed of x between a and b, when g1(x) When the value is larger than zero, the moving speed of x is larger than the preset moving speed
When g is1(x) When the value is less than zero, the moving speed of x is less than the preset moving speed; in the step of determining whether the speed of movement of the information carrier is greater than the defined speed of movement of the information carrier, a determination g is made1(x) And if yes, outputting an abnormal state with high risk of x, and if not, judging whether x is positioned in the specified sales area.
The distance s (x) between the two places a and ba，xb) Is calculated by the formula
Wherein (lonx)a，latxa)、(lonxb，latxb) And x represents the longitude and latitude of x when the places a and b are verified and judged respectively, and R represents the average radius of the earth.
For example, let latxa＝30.234，lonxa＝120.492，latxb＝31.233，lonxb＝121.491，ta=1519826653，tb＝1519826618, into the formula, to obtain
The result is 4189, the moving speed of x between a and b is 4189m/s, and if the transportation means of the goods is an automobile, the preset moving speed is 4189m/s
Generally, the maximum speed is about 28m/s after 100km/h conversion unit, and the predetermined moving speed is set in the range of 80-100km/h, if the transportation means of the commercial product is a train
Generally set in the range of 400km/h and the maximum speed of 112m/s after 400km/h conversion unit is far less than 4189m/s, i.e. the moving speed of x obviously does not conform to the actual moving condition of the commodity,
is far greater than zero, and the output x is in an abnormal state with high risk, namely the commodity is a counterfeit commodity.
Formula g for limiting and judging sales area of information carrier in geographical position condition2(x) F (ψ, lonx, latx), wherein ψ is a set of administrative areas where x is allowed to be sold, (lonx, latx) is the longitude and latitude of x when judged and verified, f (ψ, lonx, latx) is the intersection relationship of the longitude and latitude where x is judged and verified and the administrative area where x is allowed to be sold, f (ψ, lonx, latx) is equal to 1 when the longitude and latitude of x when judged and verified is within the administrative area where sale is allowed, and f (ψ, lonx, latx) is not equal to 1 when the longitude and latitude of x when judged and verified is not within the administrative area where sale is allowed; in the step of determining whether the information carrier is located in a defined sales area, i.e. determining g2(x) Whether x is equal to 1 or not, if not, outputting x as an abnormal state which is not verified, if yes, storing the judgment process and the result of the geographic position condition of x in a database, and specifically, calculating f (psi, lonx, latx) can be realized by cloud reverse geocoding, for example, the geographic/reverse geocoding work of a hundred degree company or a Gaude mapCan be used.

The calculation formula of the limited position transformation times in the manual interference condition is
Wherein, delta is the preset position transformation times of x,
denotes when s (x)i，xj) -a is greater than zero once, its value is increased by 1, otherwise its value is increased by 0; when h is generated2(x) When the number of times x is verified exceeds the limit, the number of times x is verified exceeds zeroThe fixed position conversion times delta are output to be a high-risk abnormal state; determining whether the number of times the distance between the information carriers is greater than the wheel base is greater than the number of times the information carriers have been subjected to limited position change, i.e. determining h2(x) And if yes, outputting an abnormal state with high risk of x, and if not, executing a manual interference condition judgment process of the stored information carrier and a step of sending the result to the database.
