[0053] Figure 3 This is a diagram of the traceability architecture disclosed in one embodiment of the present invention. DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0056] like Figure 1 As shown, the present invention provides a product traceability authentication method based on alliance chain, comprising the steps of:

[0057] S1. Store the encrypted traceability information and consumer review information of the entire product process, and save the hash of the encrypted traceability information and the hash of the consumer review information to the alliance chain;

[0058] in,

[0059] The product traceability information generated by the product production, transaction, and circulation process is encrypted using the elliptic curve encryption algorithm to obtain encrypted traceability information of the entire product process;

[0060] Store the encrypted traceability information of the entire product process in the Interstellar File System.

[0061] S2. Query the traceability body according to the unique identification ID of the product to be authenticated, and call the platform authentication operation and consumer authentication operation in the traceability body in parallel;

[0062] in,

[0063] like Figure 3As shown in the figure, the traceability body is an abstract description of the traceability information of the entire process of product production, transaction, and circulation. It is a data structure composed of attributes (AS), methods (MS), and operations (OPS).

[0064] Right now:

[0065] TS={AS,MS,OPS}

[0066] in,

[0067] AS = {ID, PA, SA, TA}

[0068] MS={TSInit(),GetAS(),...}

[0069] OPS={PC(),XC(),...}

[0070] AS refers to the information that needs to be saved in the entire process of product production, transaction, and circulation, including the product unique identification ID, product production process attributes (ProductionAttributes, PA), product transaction process attributes (SaleAttributes, SA), and product circulation process attributes (TransportAttributes, TA);

[0071] MS refers to the method executed on the traceability body itself, including the traceability body initialization method TSInit(), the traceability body attribute query method GetAS(), etc.

[0072] OPS refers to the operation that the user assigns to the traceability body, including the platform authentication operation PC(), the consumer authentication operation XC(), etc.

[0073] There is an inheritance relationship between traceability bodies. The creation of a child traceability body can add new properties, methods and operations. The child traceability body can inherit the properties, methods and operations of the parent traceability body, and can also rewrite the properties, methods and operations of the parent traceability body, but it cannot selectively inherit some properties, methods and operations of the parent traceability body.

[0074] S3. The platform obtains the attribute values ​​(PA, SA, TA) in the traceability body through authentication operation, and obtains the hash of the encrypted traceability information stored on the alliance chain according to the unique identification ID, and then obtains the encrypted traceability information of the entire process of the product to be authenticated. The hash value of the encrypted traceability information of each process is calculated and compared with the corresponding attribute values ​​in the traceability body to obtain the authentication result of the platform;

[0075] in,

[0076] If the hash value of the encrypted traceability information of each process is the same as the attribute value of the corresponding process in the traceability body, the platform authentication is passed and the product to be authenticated is true;

[0077] Otherwise, the platform will fail the authentication and the product to be authenticated may be genuine.

[0078] Specifically, take product A as an example:

[0079] (1) The platform certification center CC calls the chain code of the alliance chain according to the unique identification ID of product A A Query the traceability body TS A , call TS A The platform authentication algorithm PC() performs platform authentication on product A;

[0080]

[0081] (2) The platform authentication operation will be TS A PA, SA, and TA are assigned to hash1, hash2, and hash3, and IPFS is accessed based on the hash (i.e., storage location) address (PA, SA, TA) of the encrypted traceability information stored on the alliance chain to obtain the traceability information A1, A2, and A3 of the production, transaction, and circulation process of product A after encryption;

[0082] (PA,SA,TA)→(hash1,hash2,hash3)

[0083] address(PA,SA,TA)→IPFS→(A1,A2,A3)

[0084] (3) The platform authentication operation takes the hash value of A1, A2, and A3 a 、hash b 、hash c ;

[0085] hash(A1)→hash a

[0086] hash(A2)→hash b

[0087] hash(A3)→hash c

[0088] (4) The platform authentication operation uses the compare function to compare hash1 with hash a , hash2 and hash b , hash3 and hash cAfter comparison, if the two are the same, the platform authentication is considered to be successful; otherwise, the platform authentication is considered to be unsuccessful, and finally the authentication result of product A is returned to the authentication center CC.

[0089] compare(hash1,hash a )→CR1

[0090] compare(hash2,hash b ) → CR2

[0091] compare(hash3,hash c ) → CR3

[0092] IF(CR1==CR2==CR3)CR=True

[0093] ELSE CR=False

[0094] CR→CC

[0095] S4, the consumer authentication operation obtains the hash of the consumer review information of similar products to the product to be authenticated stored on the alliance chain according to the unique identification ID, and then obtains the consumer review information of similar products to obtain the consumer authentication result;

[0096] in,

[0097] The consumer review information is input into the trained FastText model, and the proportion of non-negative reviews to the total reviews is obtained as the consumer authentication result.

[0098] Specifically, take product A as an example:

[0099] (1) The certification center CC calls the blockchain chain code based on the unique identification ID of product A A Query the traceability body TS A , call TS A The consumer authentication algorithm XC() performs consumer authentication on product A;

[0100]

[0101] (2) The consumer authentication operation obtains the storage location addressEM of the consumer's comments on similar products of A stored on the alliance chain based on the ID of product A;

[0102]

[0103] (3) The consumer authentication operation accesses IPFS based on the storage location obtained in the previous step, obtains all the comments EM of consumers on similar products of A from IPFS, and puts the comments into the trained FastText model to obtain the ratio of bad comments (badEM) to non-bad comments in the total comments;

[0104]

[0105] (4) The consumer certification result CCR is obtained based on the ratio of negative reviews to non-negative reviews in the total number of reviews, and is returned to the certification center CC.

[0106]

[0107] S5. Combine the platform authentication result and the consumer authentication result to obtain the final authentication result of the product to be authenticated.

[0108] If the platform's certification result is true, then the final certification result of the product to be certified is true, and consumers who have non-negative reviews account for a certain proportion of the total reviews recognize that the product to be certified is true;

[0109] If the platform's certification result is possibly true, then the final certification result of the product to be certified is possibly true, and if there are consumers whose non-negative reviews account for a certain proportion of the total reviews, they recognize that the product to be certified is possibly true.

[0110] like Figure 2 As shown, the present invention also provides a product traceability authentication system based on alliance chain, including: a platform authentication center, a blockchain underlying platform and an interplanetary file system, the platform authentication center includes a consumer authentication module and a platform authentication module, and the blockchain underlying platform adopts a Fabric alliance chain based on a PBFT (Practical Byzantine Fault Tolerance) consensus algorithm;

[0111] Platform Certification Center, used for:

[0112] (1) Perform product platform authentication operations through the platform authentication module and determine the platform authentication results;

[0113] Among them, include:

[0114] The platform certification center CC calls the chain code in the underlying blockchain platform, queries the corresponding traceability body according to the unique identification ID of the product to be certified, and calls the platform authentication operation in the traceability body;

[0115] The platform authentication operation obtains the product production process attributes, product transaction process attributes, and product circulation process attributes in the traceability body, and obtains the hash of the encrypted traceability information stored on the Fabric alliance chain based on the unique identification ID of the product to be authenticated;

[0116] Access the Interstellar File System based on the hash of the encrypted traceability information to obtain the encrypted traceability information of the production, transaction, and circulation processes of the product to be authenticated, and obtain the hash values ​​respectively;

[0117] Compare the product production process attribute value with the encrypted traceability information hash value of the production process of the product to be authenticated, the product transaction process attribute value with the encrypted traceability information hash value of the transaction process of the product to be authenticated, and the product circulation process attribute value with the encrypted traceability information hash value of the circulation process of the product to be authenticated. If they are all the same, the authentication is passed and the product to be authenticated is judged to be true; otherwise, the authentication fails and it is judged that the product to be authenticated may be true;

[0118] The platform authentication result is returned to the platform authentication center.

[0119] (2) performing product consumer authentication operations through the consumer authentication module and determining the consumer authentication results;

[0120] Among them, include:

[0121] The platform authentication center calls the chain code in the underlying blockchain platform, queries the corresponding traceability body according to the unique identification ID of the product to be authenticated, and calls the consumer authentication operation in the traceability body;

[0122] The consumer authentication operation obtains the hash of consumer review information of similar products to the product to be authenticated stored on the Fabric consortium chain based on the unique identification ID of the product to be authenticated;

[0123] Access the Interstellar File System to obtain the consumer review information based on the hash of the consumer review information;

[0124] The consumer review information is put into the trained FastText model to obtain the proportion of non-negative reviews in the total reviews, and the consumer authentication result is obtained, which is then returned to the platform authentication center.

[0125] (3) Determine the final certification result of the product based on the consumer certification results and the platform certification results;

[0130] In this application, the product certification center sets the certification contract and certification cycle;

[0131] When the number of product authentication requests sent by consumers within a authentication cycle reaches a preset threshold, the authentication contract is triggered and the product is authenticated;

[0132] When the number of product certification requests made by consumers within a certification cycle does not reach the preset threshold, the product will be regularly certified according to the certification cycle.

[0133] For example, if the authentication period is set to 10 days and the preset threshold of the number of authentication requests is 100, the judgment process is as follows:

[0134] if (number == 100 || time == 10) then trigger the certification contract (CEC);

[0135] / / Number of consumers applying for authentication; time from the last authentication to now (in days)

[0136] The CEC contract is triggered:

[0137] number=0; / / The number of consumers applying for authentication is cleared

[0138] time=0; / / The time from the last authentication to now is cleared
