4, according to ordinal number being arranged to the 4th and the 15th translation;
5, according to logical order ciphertext is reduced into expressly.
(4). the cryptographic algorithm design
(1) design philosophy
According to encryption rule, the final task of Jia Miing is 14 numeral to be converted to 20 numeral according to this rule as can be seen.
Method of encrypting is to have arrangement numeral on the position of regular length, arrange numeral and follow ordering rule, the numeral that comprises the fixed position fill out method and by and the original position of decision and the relative shift of the row's for the treatment of numeral etc., handling the approach that sorts on the fixed length position has many, as pass through Lian Biaofa, the array method, or even the double linked list method etc.What adopt during ordering is " leaving remainder method " (relative immediately allocating method, digital analysis method, middle square method, jackknife method) of also most convenient the most commonly used in the hash algorithm, and this also is the difficult point place of this algorithm.Method all may run into conflict in which in the process of ordering no matter adopt.
If the object that will sort (no matter it is numeral or other characters) is regarded as keyword, the key of hash (Hash) algorithm is the structure of hash function.Hash function is a map list, and it makes the hash function value of any keyword by this map gained all drop within the long scope that allows of table and gets final product.
May obtain same Hash address for different keywords, just conflict.If promptly key1!=key2, and f (key1)=f (key2).Conflict (collision) that Here it is.Keyword with same functions value is called synonym (synonym) concerning this hash function.In the ordinary course of things, we wish that conflict can not avoid (remove non-keyword considerably less and table is long very long) as much as possible less fully.Because hash function is the map that is incorporated into address set from set of keywords.Usually, the set of keyword is bigger, and its element comprises all possible keyword, and the element of address set only is the address value in the Hash table.So hash function is a compression map, this just inevitable generation is conflicted.Therefore, when ordering, to handle conflict emphatically.
Cryptographic algorithm is to be sequencer procedure on the ordered set of 1-20 in address set.Conflict is meant that the Hash address that is obtained by keyword (keyword is the numeral between the 0-9 in this algorithm) is to have had record on the position of j (1≤j≤20), and then " handling conflict " is exactly the Hash address of arriving another " sky " for the record search of keyword.In the process of handling conflict, may obtain an address sequence Hi (I-1,2 ... k), and Hi ∈ [1,20].Promptly when handling conflict if another Hash address H that obtains
1Still clash, then ask next address H again
2, if H
2Still H is then asked in conflict again
3H
3And the like, until H
kDo not clash to last and (needn't worry, the address that certain existence does not conflict, reason is very simple, keyword has only 14 and can have 20 for the position of depositing keyword, be that key length is during less than address set, the permanent address of not conflicting that exists), then Hk is designated as the address in table, and Here it is handles the principle of conflicting.
Usually the method for handling conflict has open addressing method, Hash method, chain address method and public overflow area method again, and wherein the form of open addressing method is:
H
i＝（H(key)＋d
i)Modmi＝1，2，…，k(k≤m-1)
Wherein: H (key) is a hash function; M is that Hash table is long; d
iBe increment sequence, can have following three kinds to follow the example of:
(1) d
i=1,2,3 ... m-1 claims linear probing hash again;
(2) d
i=1
2,-1
2, 2
2,-2
2..., ± k
2(k≤m/2) is called quadratic probing hash again;
(3) d
i=pseudo-random number sequence claims pseudorandom to survey hash again.
Be not difficult to find that the hash function here is actually the mapping counting to the integer between 1-20 at random that 0-9 constitutes, angle from mapping, for lot number or numbering, mapping is corresponding one by one, but consider simultaneously that lot number and numbering then can be found neither mapping one by one, neither surjection (because when the numbering random number is 0, number field length position is 5, and the long position of lot number field also is 5 when the lot number random number is 4, i.e. address time conflict in this case).This function is a discrete function, can define this hash function like this
I＝H(key)
Wherein the value of key is 0-9, and the value of H (key) is the natural number between the 1-20.Key i.e. the independent variable of this hash function, and I is a dependent variable.As the lot number random number is 3 o'clock, key=3, H (key)=7.
Obviously, false proof algorithm of the present invention is a linear probing hash again.The design philosophy of bright algorithm for instance below:
According to encrypting requirement, the 4th and the 8th 's value produces at random, suppose that the value on the lot number random order is respectively 0, then the long position of lot number field should be 20 (being that initial address is the 20th position), and to establish lot number be abcdef (a, b, c, d, e, f are any numbers between the 0-9).
Corresponding to this six figure place (will be 6 for digit strings definitely, because 001234 numerical value of course not, with individual position, ten addresses only is needs in order to sort), then according to the requirement of ordering rule, as earlier from a position high position begin ordering (high-order earlier still low level can all be a digit strings because of lot number or numbering) then the absolute address` of a should be (20+3) mod20=3, the absolute address` of b should be (20+6) mod20=6.
And the like, c, d, e, the address of f should be respectively: 10,1,8,16.At this moment, digital e is on the 8th position, because the 8th to be taken by lot number machine number, i.e. conflict, at this moment the absolute address` of e should be calculated again, (8+1) mod20=9, here 8 be last absolute address` of trying to achieve, find not conflict on the 9th position, the absolute address` of abodefg should be 3,6 like this, 10,1,9,16.From above-mentioned linear probing again hash process as can be seen: as long as Hash table do not fill up, can find an address Hk. who does not clash this also be cryptographic algorithm carried out according to the place.
Summarize, false proof algorithm is based on lot number and numbering random order and on the discrete hash function that determines in itself, adopt linear probing a kind of arrangement of hashing processing conflict again, the randomness of lot number and numbering position has determined the confidentiality and the reliability of algorithm, and this is because the high complexity of security code sample space determines.
(2) design realizes
1) encryption and decryption step
From top design philosophy, encryption is that the numeric string with length-specific is arranged on the fixed length position according to encryption rule, though in advance and do not know collision position, but be not difficult to find, whenever insert data and will take one " position ", this position can be carried out mark at an easy rate, if whenever fill out data, the position at this input place promptly becomes " busy attitude " (can not insert data again), like this when running into the data that to insert this position next time, since this position be " busy attitude ", promptly clash, then wait to fill out data and seek possible " not busy attitude " position of the next one, if the next position really is not busy attitude, then insert, otherwise, continue to seek the position that is in " not busy attitude ".For no matter be lot number or numbering, the thought of arrangement all is the same, and arranging only earlier that lot number still numbers should be consistent with decrypting process.
Be not difficult to summarize the step of encryption from above analysis, below encrypting step done to describe in detail:
1.. the address space that finally will sort is set, as array or chained list (also can be double linked list), effective length is 20 and (represents with array during the specific implementation of algorithm, length is 21, do like this be since the subscript of array since 0, and final effective address label is since 1 to 20 end).The essence of encrypting is that 14 position effective digitals are arranged in length is to go in 20 the array, owing to will handle conflict, so at first need to indicate the position of conflict, the array of the position that is used for indicating conflict is set for this reason, and the length of array is for also being 21.Convenient for the narration of back, the array that title will insert 14 production numbers is the target array, and the array of mark collision position is the sign array.And the data type of target array is a character type, and the data type of sign array is an integer.
2.. aray variable.Though the original text of encrypting is numeral but generally is that (as 0012 and 0231 is the numeral that can not distinguish size to the numeral that can not compare size, certainly be to compare size on the character meaning), so being worked as character string, the original text that will encrypt treats (being digit strings).Because the requirement of encryption rule, very naturally to carry out assignment with a random number to the 5th, 16 element of target array earlier, at this moment nature will be the 1st of sign array, 5,9,16 elements are changed to " busy attitude ", and (reason is that first position is not used the effect of just having played adjusting position all the time.Other object elements are initialized as ' a ' (certainly being other nonnumeric character), and residue sign array is changed to " not busy attitude ".
3.. select the encryption sequencing of lot number and numbering.No matter be to encrypt to lot number or to numbering earlier, can both reach the requirement of encryption rule regulation, only when deciphering, to note forming corresponding with ciphering process.
4. by encryption rule lot number and numbering are encrypted separately.The detailed process of encrypting is: for an effective production number, earlier it press lot number and number separated into two parts: 6 lot numbers and 8 bit numbers.In case determined the encryption order of lot number and numbering, then ordering should be followed production number direction from left to right and carries out.Promptly concerning lot number and numbering, ordering should be undertaken by the order from a high position to the low level.The principle of following (Pos+Abs) mod20 is determined the final absolute position of the row's for the treatment of element.Determine not collision position of the next one by (ColPos+1) mod20 when handling conflict, if do not conflict, then the position of gained is the final absolute position of the row's for the treatment of element thus.Every row's one element, the mark position of putting this element place immediately is " busy attitude ", reason obviously, this position can not be arranged other any element again.Comply with. these regularly arranged intact 14 production numbers.
5. fill rest position.Fill rest position by the encryption rule requirement with random number,, filling so want earlier random number to be converted to character because the target location is the character array.
6. fill random order.Because the 8th (being the 9th element in array) is random order, and when initialization, be changed to " busy attitude ", so existing the needs this position reset is not busy attitude, and every digital translation of preceding 19 bit digital sums becomes character to insert, because the front has 5 bit digital to insert at random, so the value of this position also is at random, is fated so be called random order.
7. password conversion.Once change by the password table of comparisons arranging 20 good bit digital characters, so far encrypt and finish.
(2). the realization of inquiry
False proof id by the user, the id log sheet has been inquired about in inquiry earlier, have, tell the user that your number of input is inquired about, do not have, with supplier number inquiry manufacturer's information table, no, tell user prompt 1, have, inquire about T2 (the production code member table of manufacturer) with production code member, no, tell user prompt 1, have, with 8 goods number inquiry T3 (production code member scope table), no, tell user prompt 1, tell user prompt 2, and the voice document name that obtains is combined into the discernible form of information station, return as return results.Web is returned as related words information.
Wherein user prompt 1 is " you do not exist by the number of inquiry "; User prompt 2 is " the upright product of the material company material product that you inquire about ".

Compared with the prior art the present invention has the following advantages:
Can't forge: anti-counterfeiting technology in the past all belongs to the monobasic anti-counterfeiting technology theoretically, in fact always can forge, only the complexity difference of Wei Zaoing.What native system adopted is that security code set in every product antiforgerg identification thing all generates by special cryptographic algorithm, and security code information all is stored in central database.Even if the adulterator can forge the same product of pre-false proof marker outward appearance, meet irregular governed security code between the product but also can't puppet produce, more the security code information of forging can't be sent and deposit in the party database.
Coding is strict: the coding that is contained in every piece of anti-fake identification mark all is unique, and the mathematical algorithm by precision generates at random, never repeat, and do not have rule and rule, and be a kind of pure unordered random code, the fake producer can't copy.Code capacity reaches 10
20Thereby, satisfy large-scale needs.
Inquire about easy: verify that true and false use is simple, be suitable for operation, convenient, flexible.Traditional anti-counterfeiting technology is actually some complicated markers that adopt special material, specific process to make.Want to discern the false from the genuine, need special expertise or buy expensive instrumentation, consumers in general can't directly use anti-fake identification mark to differentiate the true and false of product basically.Adopt the product of net sign indicating number anti-counterfeiting technology, any buyer, put through the inquiry phone or enter internet system, inquire about and just know authenticity of products, thereby with a kind of technical very strong complex process, be simplified to a simple procedure of calling with internet checking, more need not know-how, equipment, training, thus make query script more afterburning just flexible, safe and reliable.
Advanced technology: extensive use current software industry, the advanced technology of internet industry, as MIDDLEWARE, CONPONMENTS, 3DS, thereby guaranteed the fail safe of this system, reliability, the advance of response real-time and technology.The false proof operating position of net sign indicating number in Baoji Cigarette Factory:
By the net code anti-fake system that the false proof Science and Technology Ltd. of a side is developed, prove repeatedly through Baoji Cigarette Factory, the frosted Monkey King cigarette of producing at Baoji Yan Chang is used with renovating on the red Monkey King cigarette.It is implemented by 20 security code and corresponding explanation all is printed on the cigarette pack barrel.
Similar false proof comparing with market has following advantage:
1. the science of net code anti-fake system itself, advance, preciseness, and right The simplification of consumer's discriminating and convenience, than the laser anti-counterfeit epoch such as the laser mark It is superior many that the technology such as knowledge, positioning bronzing are wanted.
2. with regard to digital code anti-false, by being printed on the way on the packing box, effectively Difficulty, the production process that has solved the management that way is brought such as labeling increases, corresponding production The problems such as cost increase.
These two brands with the false proof new product release of this kind after, the consumer inquires about phone Constantly, there are every day thousands of inquiry phones to squeeze into inquiry. Facts have proved that employing net code is false proof, Effect is fairly obvious.
