The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Before describing the embodiments of the present application, the jalin code algorithm used in the present application will be described.
Let the discrete random variable x have a fixed normalized probability p (x), and have a positive real number r acting on the normalized probability p (x) at any time, and mark the non-normalized probability of the discrete random variable x as

The following formula is satisfied:

the sum of the probabilities of all variables at any time is then:

and is

Assuming that the distribution function of the non-normalized probability model is F (x, r), F (x) is the distribution function of the normalized probability model, and s ∈ {0,1, …, k }, then:
Figure BDA0003052719670000056
let R0＝1，L00; the calculation formula of the ith bit symbol entropy coding is as follows:
Figure BDA0003052719670000057
Li＝Li-1+Ri-1F(x-1,r) (5)
Hi＝Li+Ri (6)
according to the information entropy theory, the size of the probability of a symbol determines the size of its self-information volume, i.e. the self-information volume i (x) with a symbol x having a probability p (x) is:
I(x)＝logp(x) (7)
the unit of the self-information quantity I (x) is related to the used logarithmic base number, the commonly used logarithmic base number in the information theory is 2, the unit corresponding to the self-information quantity is bit (bit), and therefore the information entropy is:

Figure BDA0003052719670000059
from the above, the information entropy formula of the normalized probability model of the independent discrete random sequence is as follows:
H(X)＝-p(0)log2p(0)-p(1)log2p(1) (10)
where the unit of H (X) is a bit. The information entropy formula of the non-normalized probability model of the random sequence is as follows:
Figure BDA0003052719670000061
where the unit of H (X, r) is bit, let the length of the digital fingerprint be Len, then we can obtain:
Figure BDA0003052719670000062
where p (0) + p (1) ═ 1, n is the bit length of the random sequence, and the reduction formula can be obtained:
Len/n＝-log2r+H(X) (13)
r＝2H(X)-Len/n (14)
obviously, H (X) is obtained by the normalized probability of the symbol 0 or the symbol 1 of the independent discrete random sequence, Len is setThe length of the random sequence after encoding can be obtained by substituting known r, p (0) and p (1) into equations (3) to (6) according to the information entropy theory. A digital fingerprint extracting process for binary sequence in the coding process of Jielin code includes such steps as setting digital fingerprint length Len according to random sequence, converting to positive real number r, setting up a positive real number r to make it satisfy formula (14), coding, and decodingiAs a digital fingerprint, it is also Len in length.
According to the prior art, the applicant finds that at present, a manufacturer only prints a two-dimensional code on the bottle body of a produced disinfectant when the disinfectant is produced, a user can display production manufacturer information of the disinfectant on an app by scanning the two-dimensional code through the app, no data verification and data encryption process exists, no one-object-one-code process exists, a two-dimensional code can be easily forged by a fake producer, and the problem that the prevalence of fake disinfectants in the market cannot be radically solved.
A first embodiment;
in order to solve the above problems, referring to fig. 1 and 2, one embodiment of the present invention provides a jerrin-based disinfectant validation method for a control platform, comprising the steps of:
s100, the control platform receives a request instruction for requesting the disinfection machine to use the disinfectant to execute disinfection operation, and receives a first plaintext of the disinfection machine and a second plaintext of the disinfectant.
The request instruction for requesting the disinfection machine to perform disinfection operation using the disinfectant can be from a mobile phone (for example, the mobile phone opens an app or a WeChat applet) or a disinfection machine (a plurality of function keys are arranged on the disinfection machine), and the embodiment is described by taking the request instruction from the disinfection machine as an example.
The user presses a button 'start' on the sterilizer and inputs the plaintext on the disinfectant bottle (the user can obtain the plaintext by scanning the two-dimensional code on the bottle body or the disinfectant bottle body is provided with an ID number which can be determined according to the situation), and the sterilizer sends the inputted plaintext together with the plaintext to the control platform. The sources of the plaintext are as follows:
after the disinfection machine is produced from the workshop, the producer will set a plaintext (different from the first plaintext in step S100), and after the same disinfectant is produced from the workshop, the producer will also set a plaintext (different from the second plaintext in step S100). Of course, if the producer does not set the unique corresponding plain text for the sterilizing machine and the sterilizing agent after production in the workshop, the unique corresponding plain text can be set at the time of sale.
As an alternative embodiment, the plaintext may be composed of any one or more symbols recognizable by the computer, such as numbers, letters, special symbols, Chinese characters, or even any symbols recognizable by the computer. Take the example of converting Chinese characters into binary system: 3755 primary Chinese characters, 3008 secondary Chinese characters, 682 graphic symbols and 7445 graphic symbols are collected in a character set of a national standard code (national standard information exchange Chinese character code of the people's republic of China, with the code number of GB 2312-80). A Chinese character corresponds to a zone bit code and consists of four digits, wherein the first two digits are zone codes (0-94), and the last two digits are bit codes (0-94). Meanwhile, the Chinese characters of the whole part, the Japanese and the Korean (CJK) are supported at the level of the vocabulary according to ISO/IEC 10646-1 and GB 13000-1, and the total number is 20902 characters. The information of characters, graphics, sound, animation, etc. is changed into binary number coded according to a certain rule. The machine code means that the machine code of Chinese characters in the computer takes up two bytes, which are called the high order and low order of the machine code. Their relationship to the region bit code is as follows: the high-order of the machine code is area code + A0H, and the low-order of the machine code is bit code + A0H. This can improve the extent of setting the plaintext.
For convenience of management, the manufacturer can set corresponding plaintext according to the medicament information (product name, date of manufacture, product number, special number, etc.), such as: the product name is as follows: G. the production date is as follows: 2020.01.01, product number: 06. special number: m, then according to the above information makes up, the plaintext of this product is: G2020010106M. Likewise, the disinfection machine can be provided with a plain text according to the same method, which is not described in detail here.
After the corresponding plaintext is produced and set by the sterilizer and the disinfectant, the sterilizer and the disinfectant are encoded by a Jielin code algorithm to obtain a unique hash value corresponding to the plaintext, and the hash value is stored in a database.
The jilin code algorithm used in this application is introduced here as a process of encoding a plaintext into a uniquely corresponding hash value:
and S101, converting the plaintext into a binary sequence.
S102, setting a positive real number r to 2H(X)-Len/nWhere h (x) represents the normalized information entropy of the binary sequence, Len represents the set digital fingerprint length, and n represents the sequence length of the binary sequence.
S103, for the ith bit symbol x in the binary sequence, according to a coding formula Ri＝Ri-1rp (x) and Li＝Li-1+Ri-1F (x-1, r) is coded, and L after the coding is finished is codediAs a plain uniquely corresponding hash value, where R0＝1，L00, p (x) denotes the normalized probability of the symbol x, and F (x-1, r) denotes the non-normalized distribution function of the symbol x-1.
The process of encoding the binary sequence in step S103 is specifically as follows:
initial setting: i is 0, R0＝1，L0＝0；
The first step, coding the ith symbol, and entering the second step if the ith symbol is symbol 0; if the ith symbol is symbol 1, entering a third step;
second, substituting the symbol 0 into the coding formula to obtain Ri＝Ri-1rp (0), L since F (-1, r) ═ 0i＝Li-1And proceeding to the fourth step;
here, the coding equations are equations (4) and (5) described above.
Thirdly, substituting the symbol 1 into a coding formula to obtain Ri＝Ri-1rp (1), F (0, r) ═ rp (0), so Li＝Li-1+Ri-1rp (0), and proceed to the fourth step;
here, the coding equations are equations (4) and (5) described above.
Step four, if the cyclic variable i is i +1, judging that i is less than or equal to n, and entering the first step; if i>n, ending coding and outputting V, wherein V is L after binary sequence codingiThe output V is also the hash value.
Wherein, the coding formula of the Jielin code algorithm is as follows

And Li＝Li-1+Ri-1F(x-1,r)。

s200, the control platform encodes the first plaintext and the second plaintext into a first hash value and a second hash value respectively through a Jielin code algorithm.
As mentioned above, the disinfection machine and the disinfectant are both set as a plain text at the time of production, and are encoded into uniquely corresponding hash values, which are stored in the database.
When the user uses the sterilizer, the user presses a key to start and inputs the plaintext (namely the second plaintext) on the sterilizer body, and the sterilizer sends the input plaintext together with the own plaintext (namely the second plaintext) to the control platform. Since the sterilizer and the disinfectant are produced or sold, the two plaintext received by the control platform are not necessarily the plaintext set in production, because of the possibility of being tampered, for example, the sterilizer is cracked by a third party to tamper information, the two-dimensional code on the disinfectant is tampered, and the like. Here, the encoding steps for encoding the first plaintext into the first hash value and encoding the second plaintext into the second hash value are the same as the above-described procedure, and are not described herein again.
S300, the control platform searches the hash values respectively matched with the first hash value and the second hash value in the database, and if the hash values respectively matched with the first hash value and the second hash value exist in the database, the control platform sends a use instruction to the disinfection machine, and the use instruction is used for driving the disinfection machine to use a disinfectant to execute disinfection operation.
Since the above description has been given, the database stores a plurality of hash values obtained by encoding the plain text set by the sterilizer and the sterilizer at the time of production by the jervine code algorithm. The process is not described in detail here. The technical solution of searching in the database belongs to the prior art, and therefore, the detailed description is omitted.
When the same hash value as the first hash value and the second hash value exists in the database, it means that the data of the disinfection machine and the bottle of disinfectant are not tampered, and the disinfection machine and the bottle of disinfectant belong to genuine products. When the control platform is informed that the product is genuine, the control platform sends a use instruction to the disinfection machine for driving the disinfection machine to use the disinfectant to perform disinfection operation. Otherwise, the product is not used, and a use error instruction is sent to the sterilizing machine for prompting the user that an error occurs and prompting the user to use the genuine product.
In the embodiment of the method, a producer firstly encodes the disinfectant and the unique plaintext of the disinfecting machine into the unique corresponding hash value through the Jelin code algorithm and stores the hash value in the database when the producer goes out of production or sells, and as the length of the hash value in the encoding process of the Jelin code algorithm used in the method is uncertain, the difficulty of brute force cracking is increased, so that the safety is improved. Then when the user uses the sterilizer, the user inputs the plaintext of the sterilizer, and the sterilizer sends the inputted plaintext together with the own plaintext to the control platform. And then after the control platform codes the corresponding hash value, matching the coded hash value with the hash value stored in the database, if the two hash values are consistent, verifying that the data is not falsified, and if the disinfectant in the disinfection machine and the bottle belongs to a genuine product, commanding the disinfection machine to execute disinfection operation, wherein the process is equivalent to performing one-time forced verification on the disinfection machine and the disinfectant to ensure that the disinfection machine and the disinfectant are used after the hash value verification is performed, so that the authenticity verification rate of the disinfectant can reach 100%.
The embodiment of the method has the following beneficial effects:
(1) compared with the method on the market, the method can greatly improve the safety of the disinfectant, and the disinfectant can be used only if the hash values of the disinfectant and the disinfecting machine can be completely matched, so that one object is ensured, and the fake goods on the market are prevented from being popular.
(2) The method uses the Jielin code algorithm for encryption, digital fingerprint lengths with different lengths can be selected and set, and the hash values output after the digital fingerprint lengths with different lengths are coded by the Jielin code have different lengths, so that the difficulty of brute force cracking by any third party is increased, and the safety is greatly improved.
As an optional implementation, the method further comprises the following steps:
s400, the control platform obtains the remaining use time of the disinfectant, and if the remaining use time is set to be zero, the hash value corresponding to the disinfectant in the database is deleted.
When the user uses the disinfectant, the service time of a bottle of disinfectant is calculated, and after the service time is over, the corresponding hash value of the bottle of disinfectant stored in the database can be invalid, so that one object and one code are fundamentally ensured, a counterfeit party can be found without trace, and the problem that the counterfeit party or the user adds the self-made disinfectant again on the original bottle after using the bottle of disinfectant is also avoided.
Wherein, the step of obtaining the residual using time of the disinfectant comprises the following steps:
s401, acquiring the room area of the disinfection machine for executing the disinfection operation, searching the working time from the database based on the room area, and acquiring the residual using time of the disinfectant based on the working time and the using time of the disinfectant.
The room area is input by a user, the database comprises an expert database, and corresponding working time is found in the expert database (a plurality of templates are stored in the expert database) based on the input room area. The remaining time of use of the disinfectant can then be obtained based on the working time and the time the disinfectant can be used (since there are instances where the working time is less than the time the disinfectant can be used). It is emphasized that the present application does not consider the adjustment of the disinfectant spray rate, but defaults to a uniform spray.
A second embodiment;
referring to fig. 3, one embodiment of the present invention provides a jerry code-based disinfectant validation system comprising: disinfectant, sterilizer, database, control platform, wherein:
the disinfectant is used for providing disinfectant.
The sterilizer is used to perform a sterilization operation using a disinfectant.
