Having described the general principles of the invention, reference will now be made in detail to various non-limiting embodiments of the invention, examples of which are illustrated in the accompanying drawings.

Example one

Referring to fig. 1, the present invention provides a data security management method for material purchasing, wherein the method is applied to a data security management system for material purchasing, the system includes a task management module, a bid inviting management module, an expert review module, and a purchasing management module, and the method specifically includes the following steps:

step S100: obtaining a first purchasing task of a first material purchasing item, wherein the first purchasing task comprises a first purchasing material and a first purchasing quantity;

specifically, the data security management method for material purchasing is applied to the data security management system for material purchasing, and can perform the management of the same whole flow of purchasing, bidding, opening and purchasing of material online purchasing by using a computer technology, and ensure the data privacy security of both the bidding party and the bidding party by using a data security exchange technology, thereby achieving the effect of improving the material purchasing efficiency while ensuring the online material purchasing security and stability. The first material purchasing item is any item to be used for performing material purchasing data management by using the data safety management system. The first purchasing task refers to a task order of any purchasing material in the first material purchasing project. The first purchasing task comprises related information such as material types, quantity, purchasing time, purchasing departments and the like to be purchased. For example, in a large carbon fiber three-dimensional weaving project, there are a plurality of purchasing tasks such as purchasing carbon fiber materials, wood molds and weaving consumables, and each purchasing task specifically includes relevant information such as size, model and payment mode of the material to be purchased.

By obtaining the first purchasing materials and the first purchasing quantity, the technical effect of providing basic information for follow-up intelligentized drawing-up bidding documents based on actual purchasing tasks is achieved.

Step S200: analyzing the first procurement material and the first procurement quantity by utilizing the task management module to generate a first bidding document;

specifically, the task management module is used for intelligently managing a plurality of purchasing tasks in each material purchasing project, and tracking and managing related information such as purchasing demands, purchasing progress and the like of each purchasing task. The task management module identifies the purchasing requirements in the first purchasing task, namely information such as purchasing materials and purchasing quantity, and then the first bidding document is automatically generated by the collection bidding template and is used for online bidding quickly, intelligently and efficiently. By generating the first bid inviting file, a basis is provided for subsequently acquiring information such as quotations of all suppliers, and the effect of intelligent bid inviting is achieved.

Step S300: collecting bidding information of the first bidding document to form a first bidding information set, wherein the first bidding information set comprises a plurality of bidding information of a plurality of suppliers;

step S400: extracting first bidding information and second bidding information of the plurality of bidding information;

specifically, the task management module in the data security management system automatically extracts information, and the automatically generated first bid inviting file is intelligently issued, that is, the bid inviting announcement is intelligently issued, so that each supplier checks the bid inviting announcement, and bids based on actual production, sales and other conditions. And after the bidding time expires, the data security management system automatically acquires all bidding information below the first bidding document, and all supplier bidding information forms the first bidding information set. Further, the bid information of each supplier in the first bid information set is extracted and analyzed. The first bidding information is bidding information of any one supplier in the first bidding information set, and the second bidding information is bidding information of any one supplier in the first bidding information set, which is different from the supplier corresponding to the first bidding information.

The system automatically collects the bidding information when bidding is stopped, and the bidding information is sequentially extracted to obtain the bidding data of a plurality of suppliers, so that the bidding documents are kept in a confidential and safe state before bidding opening, the requirements of related laws and regulations are met, the supplier bidding information is quickly obtained, and the technical effect of providing a foundation for the subsequent establishment of purchasing and selling cooperation is achieved.

Step S500: sequentially determining a first decryption station of the first bidding information and a second decryption station of the second bidding information by using the bidding management module, and respectively obtaining first decryption information of the first decryption station and second decryption information of the second decryption station;

specifically, the bid inviting management module is configured to analyze, decrypt, and manage each bid information in the first bid information set. Because the online network environment has unsafe factors, in order to guarantee the safety of private data of both bidding parties and prevent data such as quotation of bidding suppliers from being leaked and even tampered, thereby causing the problems of unfairness and justice and incoordination of bidding suppliers, the data safety management system automatically encrypts the bidding information of each supplier. Further, when the tenderer, that is, the data security management system, analyzes and processes the bid information of each provider, the data bid by each provider is first sent to each decryption station, and is decrypted by the decryption station, so that the data submitted by each provider is obtained, and the information bid by the first provider, that is, the first decryption information, is obtained, and the information bid by the second provider, that is, the second decryption information is obtained. Through obtaining the first decryption information and the second decryption information, the bid information such as quoted prices submitted by each supplier is obtained, and the technical effect of providing a direct data basis for the follow-up system to intelligently evaluate each supplier and the bid information thereof is achieved.

Step S600: comparing and evaluating the first decryption information and the second decryption information by using the expert review module, determining first winning bid information, and determining a first purchasing contract according to the first winning bid information;

specifically, after decryption information bid by each provider is obtained, each decryption information is issued to each relevant domain expert of the expert review module, each expert independently analyzes and preliminarily evaluates information such as supply and quote of each provider, and then an evaluation group consisting of the experts in the expert review module performs reevaluation, and finally determines the first bid-winning information, namely the winning provider and the bid information of the provider, based on comprehensive strength and quote of each provider. For example, in a three-dimensional weaving mold bid, three suppliers' bids are obtained, the bid notice specifies 3 specific molds, wherein the first supplier can deliver the specific molds with the full amount, the price quoted is 6000 yuan, and the packages are delivered to the customer-specified place, the mold price of the second supplier is 5500 yuan but not the delivery cost, the mold price of the third supplier is 5800 yuan, the current spot goods are 2, and the 3 rd mold can complete the delivery within one month and is delivered to the customer factory. After the system sends the bidding data of the three suppliers to the expert review module, each expert scores each supplier based on the bidding requirement by logging in the system. The first expert subjectively evaluates a first supplier, a second supplier and a third supplier in sequence, and scores are 70, 65 and 68 in sequence; similarly, the second expert subjectively evaluates the first supplier, the second supplier and the third supplier sequentially, and the scores are 75 scores, 70 scores and 65 scores sequentially; the third expert subjectively evaluates the first supplier, the second supplier and the third supplier in sequence, and the scores are 65 points, 63 points and 64 points in sequence. Further, the system automatically calculates the average value of the primary evaluation of the experts on each supplier, and the specific calculation method is as follows:

wherein S is an average value of the evaluation of the experts on the suppliers, Z is the expert, n is the number of the experts, and m is the number of the suppliers.

The average value of all experts for the first supplier preliminary evaluation is 70, the average value of all experts for the second supplier preliminary evaluation is 66, and the average value of all experts for the third supplier preliminary evaluation is 65.67 according to formula calculation. And further performing detailed review on the scoring condition and the condition of each supplier by the expert group, generating a related report of scoring data, performing score fine adjustment on each supplier based on the principle that a minority obeys majority, finally determining the supplier with the highest score as a winning bid supplier, and automatically issuing winning bid announcements by the system.

Through the expert evaluation module, the bidding documents of all suppliers are evaluated and the final winning bid suppliers are determined, so that the technical effect of improving the fairness and the rationality of bidding document evaluation is achieved.

Step S700: and the purchasing management module carries out the first purchasing task according to the first purchasing contract.

Specifically, a first bid-winning announcement is automatically issued based on the system, a first purchasing contract is automatically generated based on the bidding document of a bid-winning provider, and then the purchasing management module automatically performs purchasing supervision on the first purchasing contract, including the whole process links of contract execution such as pre-payment of deposit, material delivery, acceptance check, payment settlement of the tail and the like. The purchasing management module supervises and executes the purchasing contract, thereby achieving the technical effects of improving the standardization and the high efficiency of material purchasing.

Further, as shown in fig. 2, step S500 of the present invention further includes:

step S510: analyzing the first bidding information and the second bidding information in sequence by using a content analysis method to respectively obtain a first bidding plaintext and a first bidding ciphertext, and a second bidding plaintext and a second bidding ciphertext;

step S520: the first bidding ciphertext and the second bidding ciphertext are bidding information processed by a first preset encryption algorithm;

step S530: sequentially calculating the data volume of the first bid cryptograph and the second bid cryptograph, and performing descending order according to the data volume to obtain a first order list;

step S540: and the bid inviting management module is respectively matched with a first decryption platform of the first bid ciphertext and a second decryption platform of the second bid information according to the first ranking list.

Specifically, the content analysis method is a method for objectively, systematically and accurately describing the contents of a document based on a bid document, and is a method for extracting and understanding information in each bid price to quantify information of each bid document. And obtaining specific data information of the bidding documents of each supplier according to the content analysis method, wherein each bid comprises a bidding plaintext and a bidding ciphertext. The plaintext is an original form of the bidding information, and the ciphertext is a form obtained by performing encryption transformation on the plaintext. In the bidding document, data information needing important viewing and protection is encrypted, and only the tenderer has decryption and viewing permissions. The first preset encryption algorithm is an algorithm mode for encrypting supplier bid data in the data security management system and is preset by the system. Such as symmetric key encryption, multiple DES encryption, etc.

Further, before sending the bid information of each supplier to each decryption station for decryption, the data volume of the bid ciphertext corresponding to each supplier in the bid file of each supplier is calculated, and the ciphertext of each supplier is sorted according to the sequence of the calculation result of the data volume from large to small, so that the first sorting list is formed. And at the moment, the bid inviting management module is respectively matched with decryption tables with corresponding performance and decryption speed to decrypt the ciphertext according to the first ranking table. By arranging the decryption stations based on the data volume of the ciphertext, the load balance of the decryption stations is ensured, and the technical effect of improving the decryption speed of the bid ciphertext is achieved.

Further, the present invention further includes step S550:

step S551: establishing a ciphertext category set according to the first bid ciphertext and the second bid ciphertext, wherein the ciphertext category set comprises a plurality of categories;

step S552: sequentially calculating the comprehensive association degrees of various types of the multiple types by utilizing a grey association analysis algorithm to form a first comprehensive association index set;

step S553: performing descending order on all the comprehensive correlation indexes in the first comprehensive correlation index set to obtain a second ordered list;

step S554: performing confidentiality division on the second sorted list based on a preset confidentiality division scheme to obtain a first division result;

step S555: the first decryption station decrypts the first bid ciphertext by using a first preset decryption algorithm according to the first division result to obtain first decryption information;

step S556: and the second decryption station decrypts the second bid ciphertext by using a first preset decryption algorithm according to the first division result to obtain second decryption information.

Specifically, after each decryption station receives the corresponding bid ciphertext to be decrypted, each decryption station extracts each bid ciphertext category in all received bid ciphertexts, and then performs union operation to obtain the ciphertext category set. For example, if a bid ciphertext received by a decryption station includes a unit price and a quantity in a first bid ciphertext, a subscription amount, a total price and a delivery mode in a second bid ciphertext, and a unit price and a delivery site in a third bid ciphertext, a ciphertext category set is obtained, which includes the unit price, the quantity, the subscription amount, the total price, the delivery mode and the delivery site.

Further, a grey correlation analysis algorithm is used for calculating the correlation degree between each category and other categories in the ciphertext category set respectively, and an average value is calculated to obtain the comprehensive correlation degree of the categories. For example, if the association degrees of unit prices with quantity, order amount, total price, distribution mode and distribution place are 0.55, 0.40, 0.85, 0.35 and 0.15 respectively, the comprehensive association degree of unit prices is calculated to be 0.46, and the association degree index of unit price category is obtained to be 46 through normalization processing. And then the comprehensive association degrees of all the categories in the ciphertext category set form the first comprehensive association index set. And then, arranging the comprehensive association degrees in the first comprehensive association index set from large to small, and performing confidentiality division on the sequencing result based on a preset confidentiality division scheme. The preset secret dividing scheme is a method for dividing the secret degree of the ciphertext, which is determined by the system based on comprehensive analysis of the performance of the decryption table, the total amount of the ciphertext to be decrypted, the decryption timeliness requirement and the like. For example, the comprehensive association degree indexes of unit price, quantity, order amount, total price, distribution mode and distribution place are respectively 46, 38, 45, 48, 30 and 12, and the comprehensive association degree indexes are arranged in descending order as the total price, the unit price, the order amount, the quantity, the distribution mode and the distribution place according to the preset secret division scheme 1:2:3, obtaining the category of the first secret level comprising unit price, the category of the second secret level comprising quantity and order amount, and the category of the third secret level comprising total price, delivery mode and delivery place.

Further, according to a first division result, the first decryption stage sequentially decrypts the first bid cryptograph and the second bid cryptograph by using the first preset decryption algorithm to obtain first decryption information and second decryption information respectively. The first preset decryption algorithm and the first preset encryption algorithm have a corresponding relation. That is, when decrypting the first bid ciphertext, the categories of the third confidentiality level are decrypted in sequence, then the categories of the second confidentiality level are decrypted in sequence, and finally the categories of the first confidentiality level are decrypted in sequence. For example, the total price, the distribution mode and the distribution place of the third secret level are decrypted first, then the number and the ordering amount of the second secret level are decrypted, and finally the unit price of the first secret level is decrypted. The classification of the confidentiality grade is carried out based on the comprehensive association index of the ciphertext class, and the class with different confidentiality grades is subjected to priority decryption sequencing, so that the technical effects of refining a decryption mechanism and improving the stability and the decryption orderliness of a system are achieved.

Further, step S555 of the present invention further includes:

step S5551: extracting a first secret category of the first division result;

step S5552: decrypting the first secret category for a preset number of times according to the first preset decryption algorithm to generate a first decryption report;

step S5553: if the first decryption report shows that the decryption is abnormal, a first calling instruction is obtained, and a second preset decryption algorithm is obtained according to the first calling instruction;

step S5554: decrypting the first secret category for the preset times according to the second preset decryption algorithm to generate a second decryption report;

step S5555: if the second decryption report shows that the decryption is abnormal, a first early warning instruction is obtained;

step S5556: and carrying out temporary manual decryption according to the first early warning instruction.

Specifically, when the first preset decryption algorithm is used for dividing each classified secret grade category, the system automatically performs repeated decryption for a preset number of times aiming at various abnormal decryption conditions such as missed decryption, misunderstanding, decryption interruption and the like. For example, the same bid amount is decrypted 3 times by using the first predetermined decryption algorithm. And then a first decryption report generated by decryption for a preset number of times is obtained. And at the moment, the system automatically checks the first decryption report, automatically obtains a first calling instruction when decryption abnormality is displayed in the first decryption report, and automatically calls a second preset decryption algorithm according to the first calling instruction. The second preset decryption algorithm is another method, different from the first preset decryption algorithm, for decrypting the first preset encryption algorithm, that is, the second preset decryption algorithm is a standby method of the first preset decryption algorithm. Similarly, the first secret category is decrypted for the preset times according to the second preset decryption algorithm, and a second decryption report is correspondingly generated. When the decryption abnormality does not appear in the second decryption report, the system indicates that the decryption of the bid ciphertext is completed, and the system enters the next step, however, when the decryption abnormality is displayed again in the second decryption report, the system automatically sends out a first early warning instruction for reminding relevant operators to perform temporary manual decryption.

The second decryption algorithm is preset to be used as backup and supplement of the first preset decryption algorithm, so that the probability of successful decryption is improved, and when the two preset decryption algorithms are abnormal in decryption, the system automatically reminds the user to perform manual decryption, so that the technical effects of improving the success rate of decryption and intelligentizing decryption are achieved.

Further, as shown in fig. 3, the present invention further includes step S800:

step S810: establishing a first material purchasing index parameter set according to the first purchasing task, the first bidding information set and the first purchasing contract, wherein the first material purchasing index parameter set comprises a plurality of index parameters;

step S820: utilizing the expert review module to sequentially perform comprehensive analysis and evaluation on the index parameters to establish a first evaluation result set;

step S830: analyzing the first evaluation result set by using a block chain technology to generate a first index parameter consensus chain;

step S840: and constructing a material purchasing database according to the first index parameter consensus chain.

Specifically, all file data related to the purchase in the first material purchase item are intelligently integrated, including a first purchase task received by a system before purchase, a first bid information set in the process of executing the first purchase task, and a first purchase combination set which is drawn up and executed after bidding suppliers who bid for winning a bid are determined, so that the first material purchase index parameter set is obtained. And the expert evaluation module sequentially analyzes and evaluates the index importance, confidentiality and the like of the index parameters, processes and analyzes the evaluation result by using a block chain technology to form expert consensus of each index parameter, namely, a first index parameter consensus chain is formed, and finally the material purchasing database is obtained. The material purchasing database is constructed by utilizing the block chain technology, so that the technical effects of improving the storage safety and transparency of data resources are achieved.

Further, as shown in fig. 4, the present invention further includes step S850:

step S851: the method comprises the steps of establishing a first user role set, wherein the first user role set comprises a first role and a second role;

step S852: extracting a first authority consensus chain of the first index parameter consensus chain, obtaining a first authority of the first role and a second authority of the second role according to the first authority consensus chain, and constructing a role-authority list;

step S853: obtaining first role information of a first login user, and matching a first management authority by using the role-authority list;

step S854: and the first login user carries out operation management on the material purchasing database based on the first management authority.

Further, the present invention further includes step S855:

step S8551: obtaining first operation management information of the first login user, wherein the first operation management information comprises first operation management time and first operation management content;

step S8552: and generating a first operation management log of the material purchasing database according to the first operation management time and the first operation management content.

Specifically, a set of all roles of the data security management system is constructed, and then permission consensus of each role in the set is extracted based on the first index parameter consensus chain, so that a first permission of the first role and a second permission of the second role are obtained respectively, and thus a corresponding relationship between the roles and the permissions is constructed, and a role-permission list is obtained. After the user logs in the data security management system, the system automatically identifies the role identity of the user, and further matches the authority of the user based on the role-authority list. And finally, the user carries out related operations such as data sorting, correction, classification, regular backup and the like on the material purchasing database based on the first management authority. When the first login user performs related operations on each data in the material purchasing database, the system automatically records the information of the user operation management, including related information such as login information, operation time, operation content, IP (Internet protocol) used for operation and the like, so as to generate operation logs, and the operation logs of all users comprehensively generate a first operation management log of the material purchasing database.

By endowing different data viewing and processing authorities to different user roles, the technical effect of improving the confidentiality and the safety of the conventional material purchasing data is achieved; by generating the operation management log of the material purchasing database, the technical effects that the operation can be traced and the overall safety of the database is improved are achieved.
