Description
Technical field
The present invention relates to planar bar code technology, more particularly to a kind of commodity counterfeit prevention and lottery drawing method based on polynomial interopolation.
Background technology
Businessman produces commodity after substantial amounts of manpower and materials have been put into, but pseudo- often over copying when flowing in the market
Dress is replaced.Criminal goes processing using commercial factor more inferior, is turned on same plate and arrives by imitating content of good
Sold in market, therefrom obtain interests.This not only allows businessman to have lost the interests of oneself, also allows the interests for compromising client.
In view of this, existing some producers are carried out false proof when producing commodity using planar bar code technology.Produced
When product are produced, one section of random sequence number of commodity is randomly assigned to, Quick Response Code is generated according to sequence number.Quick Response Code is then printed on
On product external packaging, producer of enterprise adds corresponding identifying code and lottery numbers in database, and sequence number is then pasted onto commodity
On.In order to prevent commodity to be opened before purchase, packaging bar sticks in outer package mouth in businessman.User when in use, passes through mobile phone
Special APP is downloaded, Quick Response Code is scanned using special APP, the input fake certification code checking authenticity of products in the checking page, in order to
Rebating is promoted, after being proved to be successful, and a prize drawing code can be also returned to user, for drawing a lottery.
From above-mentioned existing technical scheme, sequence number is saved in the database of the server end of businessman, identifying code,
Prize drawing code, corresponding prize or bonus etc., if commodity amount is especially huge, such as beverage is then stored greatly in database side
The data of amount, are required for from database retrieving sequence number in examining every time, then remove authentication code, are verified this slows down us
Speed.
The content of the invention
To overcome the deficiencies in the prior art there is provided a kind of simplified storage, the antiforge method for commodities of fast verification, the present invention is carried
A kind of antiforge method for commodities based on polynomial interopolation is gone out.

S3：User scans the Quick Response Code using special APP, and inputs prize drawing code；
S4：Special APP obtains sequence number according to the Quick Response Code, and the sequence number and prize drawing code are sent to server
End；
S5：Server end reconstructs multinomial according to the sequence number, and whether calculates the prize drawing code in the multinomial
On curve, to verify whether product is to get the winning number in a bond.
The present invention also proposes another commodity lottery drawing method based on polynomial interopolation, including step：
S1：Each product one sequence number of correspondence, the whole or one part of sequence number is multinomial for generating one
Formula, server end stores sequence number prize drawing code corresponding with the sequence number；
S2：The sequence number is converted into Quick Response Code, is attached at product external packaging, identifying code is affixed on product inner packing；
S3：User scans the Quick Response Code using special APP, and special APP reconstructs multinomial according to the sequence number；
S4：User's input validation code, the special APP calculates identifying code whether on the polynomial curve, to verify
Whether product is certified products, is such as verified, then sends the sequence number to server end；
S5：Whether server end reconstructs multinomial according to the sequence number, and verify the prize drawing code in the multinomial
On curve, to verify whether product is to get the winning number in a bond.
The beneficial effects of the present invention are compared with prior art, present invention checking authenticity of products enters at special APP ends
OK, the pressure of server is alleviated, verifying speed is accelerated；Optimize storage scheme, server-side database data storage compared with
It is small.

Below by taking second order polynomial as an example, illustrate the inventive concept of the present invention.
As shown in figure 4, randomly generating a quadratic function formula when taking sequence number, three point x are taken at random in the picture1、x2、
x3, its abscissa and ordinate are merged into (x1y1x2y2x3y3), as the sequence number for producing Quick Response Code, one is taken on its image
Point (x4, y4) it is used as identifying code (x4y4).Lottery numbers take a bit (x from coordinate at random5, y5), get the winning number in a bond with otherwise examining (x5,
y5) whether in quadratic function formula f (x)=ax2On+bx+c.
Quadratic function formula f (x)=x is randomly generated in reference axis2, four point x are taken at random on image1(1,1)、
x2(2,4), x3(3,9), x4(4,16), randomly select a point x5(5,13) as lottery numbers, by x1、x2、x3Each seat
Mark is all expressed as that (0,000 0001,0,000 0001) (0,000 0010,0,000 0100) with 8 binary ASCII code forms
(0000 0011,0000 1001)
Above-mentioned binary ASCII code is subjected to arrangement generation image as shown in Figure 5.The two of sequence number (112439) are entered
System is arranged in order.Numeral 0 becomes white, and numeral 1 becomes black and is written as Quick Response Code.Add and correspond to therewith in database
Identifying code (4,16) with prize drawing code (5,13).
The verification method of the special APP of client and server end is basically identical：
User scans Quick Response Code using special APP, the input validation code in the checking page；
The Quick Response Code sequence number after scanning is obtained, Quick Response Code sequence number is divided into three coordinates in rows；
Calculated in server using three coordinates, draw quadratic function formula, after being verified, prize drawing code is substituted into two
Tested in secondary functional expression, examine and successfully then show prize-winning.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
