A blockchain-based production status verification method, device, and electronic device

Abstract

An embodiment of this specification provides a method for verifying production status based on a blockchain. The production status information of a first device for a first object is collected through sensors, and the production traceability information of the first object is obtained by a traceability application. Using a preset consistency rule, the production status information and the production traceability information are verified for consistency to obtain a consistency verification result. The first business party signs it and uploads it to the blockchain system. The certificate platform signs the public key of the first business party. The blockchain system obtains the public key of the first business party to authenticate the identity of the consistency verification result. If the verification passes, the consistency verification result is provided to the demand side of the first object. By collecting the production status information of the first device for the first object through sensors and combining with the preset consistency rule, the production traceability information can be verified. Since the production status information can prove the actual production situation, anomalies in the production traceability information can be identified, and thus scanning operations that do not conform to the rules can be identified.

[0048] The term "and / or" or "and / or" includes all combinations of any one or more of the associated listed items.

[0049] Figure 1 A schematic diagram of a blockchain-based production status verification method provided in an embodiment of this specification, the method may include:

[0050] S101: Collecting production status information of a first device on a first object through a sensor, and obtaining production traceability information of the first object collected by a traceability application.

[0051] In some high-tech enterprise processing plants, an MES traceability system is also configured to scan the QR code of the goods to be processed when they pass a certain station to record the information.

[0052] In fact, for OEM production, the ultimate goal of our management and control is to prove the authenticity of the production progress. The core is to verify whether the actual production speed is consistent with the scanning speed, or to prove to the demander that the actual production speed is consistent with the scanning speed. Because, for each processing site that needs to scan MES, if it is processed one by one, then the scanning speed should be consistent with the processing speed. If 100 pieces are scanned in 5 minutes, but 100 pieces cannot be processed in 5 minutes, then it means that there is a situation of batch scanning and batch processing.

[0053] Or, if 50 pieces are scanned in 10 minutes and it takes 20 minutes to process the 50 pieces, then this can also indicate that batch scanning and batch processing exist.

[0054] To control the actual production speed, we can use piece count sensors, temperature sensors or needle count sensors. We can directly collect the processing time of each piece of clothing through the piece count sensor to calculate the processing speed.

[0055] Therefore, in the embodiment of the present specification, the production status information includes at least one of needle movement information and piece number sensing information.

[0056] In order to avoid the situation where the factory deliberately forges the clothes to be passed, we can monitor the actual number of clothes processed by the number of stitches.

[0057] We can also use a speed sensor to sense the speed at which the clothes are being conveyed, and to determine whether there is an actual processing process. If the speed of conveying the clothes exceeds the threshold, it indicates that the processing factory is deliberately forging the passing of clothes.

[0058] For example, if it takes 10 seconds to process a piece of clothing, but the data collected by the speed sensor shows that each piece of clothing passes through in 1 second, it means that the clothes have not been actually processed.

[0059] The number of stitches can be collected through a stitch sensor.

[0060] Therefore, the stitch information can include the stitch times of each stitching action. The stitch information can also include the total number of stitches.

[0061] Wherein, one stitch refers to one back-and-forth movement of the needle tip, such as one up-and-down movement.

[0062] Specifically, we can use an IoT (Internet of Things) clothing manufacturing device equipped with multiple sensors to collect the production status information of the first device for the first object.

[0063] Among them, the traceability application can be an application of the traceability platform, such as the MES system. Of course, it can also be its own built-in system, which is not limited here.

[0064] Among them, the production traceability information can be the first object identifier entered and the entry time.

[0065] It can be entered by manual filling or by scanning, which is not limited here.

[0066] The first object here can be clothes or other commodities, such as knitting supplies.

[0067] In actual application, the number of sewn pieces, equipment status and other data of the clothing manufacturing equipment during the workers' operation can be collected through the IoT hardware unit. Each sensor is respectively installed at the corresponding position of the clothing manufacturing equipment and is connected to the IoT control box.

[0068] S102: Use a preset consistency rule to perform consistency verification on the production status information and the production traceability information, and obtain a consistency verification result.

[0069] Among them, the production speed and the number of production pieces can be calculated respectively according to the production status information and the production traceability information, and it is judged whether they are consistent.

[0070] Therefore, the use of the preset consistency rule to perform consistency verification on the production status information and the production traceability information can include:

[0071] Calculate the number of produced parts and the production speed using the needle movement information, calculate the number of scanned parts and the scanning speed according to the production traceability information, and compare the number of parts and the speed respectively using a preset consistency rule to obtain a consistency verification result.

[0072] The consistency verification result here can be consistent or inconsistent.

[0073] S103: The first business party signs and uploads the consistency verification result to the blockchain system.

[0074] By signing and uploading the consistency verification result to the blockchain system, a tamper-proof consistency verification result can be obtained, thereby improving credibility.

[0075] Here, it can refer to multiple block nodes storing the signed consistency verification result.

[0076] In this way, when it is necessary to verify the authenticity later, after each block node decrypts the signature, voting can be carried out, thus achieving the effect of preventing tampering.

[0077] Of course, we can also sign and upload the production status information and the production traceability information to the chain for voting, and let the blockchain and even the demand side of the first object conduct consistency verification.

[0078] The demand side of the first object refers to the business party that needs the foundry to process products for it.

[0079] Optionally, the first business party signing and uploading the consistency verification result to the blockchain system includes:

[0080] Sign the consistency verification result to obtain a first signed result;

[0081] Sign the production status information and the production traceability information to obtain a second signed result;

[0082] Upload the first signed result and the second signed result to the blockchain system.

[0083] Of course, it can also be to encrypt the consistency verification result using a hash algorithm, upload the hash verification code to the blockchain and obtain a block identifier.

[0084] S104: The blockchain system obtains the public key of the first business party to authenticate the consistency verification result. If the verification passes, it provides the consistency verification result to the demand side of the first object.

[0085] This method collects the production status information of the first device for the first object through sensors, obtains the production traceability information of the first object collected by the traceability application, and uses a preset consistency rule to verify the consistency of the production status information and the production traceability information to obtain a consistency verification result. The first business party signs it and uploads it to the blockchain system. The certificate platform signs the public key of the first business party. The blockchain system obtains the public key of the first business party to authenticate the identity of the consistency verification result. If the verification passes, the consistency verification result is provided to the demander of the first object. By collecting the production status information of the first device for the first object through sensors and combining with the preset consistency rule, the production traceability information can be verified. Since the production status information can prove the actual production situation, the abnormality of the production traceability information can be identified, and thus the scanning operation that does not conform to the rule can be identified.

[0086] In the embodiment of this specification, the blockchain system obtaining the public key of the first business party to authenticate the identity of the consistency verification result may include:

[0087] The certificate platform obtains the public key of the first business party and qualification verification information, verifies the qualification verification information, and if the verification passes, uses the private key of the certificate platform to sign the public key of the first business party to obtain a signed result of the business party's public key;

[0088] The certificate platform signs the public key of the first business party;

[0089] The blockchain system obtains the signed result of the business party's public key corresponding to the consistency verification result, decrypts it using the public key of the certificate platform, and compares the decryption result with the public key of the first business party. If the comparison is consistent, the identity of the consistency verification result is authenticated.

[0090] In the embodiment of this specification, this method may further include:

[0091] Obtain the public key of the demander of the first object, and encrypt the second signed result using the public key of the demander of the first object.

[0092] In the embodiment of this specification, if the first business party uploads the consistency verification result signed to the blockchain system, it includes:

[0093] Sign the consistency verification result to obtain a first signed result;

[0094] Sign the production status information and the production traceability information to obtain a second signed result;

[0095] Upload the first signed result and the second signed result to the blockchain system;

[0096] Then, the method may further include:

[0097] Obtain the business party public key corresponding to the second signing result, and use the business party public key to decrypt the signature;

[0098] Using the preset consistency rules, the decoded production status information and production traceability information are verified for consistency, and the consistency verification results of the on-chain nodes are obtained.

[0099] If workers count one bundle as one work ticket, and scan the code on the work ticket and submit it before sewing, inconsistent results will be obtained, thus identifying the situation of exaggerated production capacity.

[0100] In this way, the platform and order demanders can ensure that they can obtain credible and authentic traceability information from the foundry, obtain tamper-proof production data, and verify the identity reliability of the digital factory.

[0101] In actual application, brands and e-commerce platforms can also obtain historical information of each OEM factory to screen qualified OEM factories, and can quickly match authentic and trustworthy OEM factories with endorsements, without the need for a large number of merchandisers to travel to confirm whether the production capacity reported by the OEM factory is consistent with the actual situation.

[0102] Signing and de-signing belong to the existing technology, which refers to processing through asymmetric key pairs. Using the private key to process is signing, and de-signing can be used for identity identification. Signing can also have the effect of encryption, and decryption can be achieved through de-signing.

[0103] If targeted encryption is required, the public key of the demander can be obtained and encrypted. In this way, only the demander can correctly decrypt the data, thereby performing consistency verification.

[0104] Among them, for each foundry, the factory identification, worker identification, and garment equipment identification can be used to distinguish. For example, the factory identification, worker identification, and garment equipment identification are added to the blockchain through an encryption algorithm. The cloud factory identification, worker identification, and garment equipment identification can also be bound as user names and encrypted to join the blockchain. The platform organization digitally signs the on-chain data of the cloud factory with an identity identification and issues the digital factory certificate.

[0105] The key, from which the block address can be obtained through an encryption algorithm.

[0106] MES can also collect data such as the clothing cloud factory's production capacity, work point records, worker wages, and order completion.

[0107] The certificate platform may have public key information, clothing cloud factory identity information, institutional digital signature, public key information, used to obtain the digitalization degree {d} of clothing workers through analyzing the consistency verification result and encrypt it; clothing cloud factory identity information, used to identify the identity of the cloud factory, that is, the holder of the certificate private key.

[0108] During specific verification, the data storage unit can separately obtain and store the sewing IoT data set {a} collected by the IoT hardware according to time period, factory identifier, device identifier, worker identifier, and process identifier, as well as the production data set {b} recorded by the cloud MES software in terms of time period, factory identifier, worker identifier, and work ticket.

[0109] Compare whether the data in the sewing data set {a} matches the production data set {b} for consistency comparison.

[0110] If the comparison data is consistent, the verification data passes to obtain the proof information {c0}. If it is judged inconsistent, the verification fails to obtain the proof information {c1}.

[0111] For the certificate platform, certificate management can be carried out: The clothing cloud factory applies for a certificate to the certificate platform. The clothing cloud factory provides public key information and the verification evidence and verification data required by the certificate platform. The certificate platform verifies the data and issues a certificate to the public key. The certificate platform digitally signs the public key of the clothing cloud factory with its own private key. The verifier (such as the requester) uses the digital signature algorithm to verify the identity of the clothing cloud factory and the correctness of the digital factory certificate.

[0112] Figure 2 It is a schematic structural diagram of a production status verification device provided by an embodiment of this specification. The device may include:

[0113] The acquisition module 201 acquires the production status information of the first device for the first object through a sensor, and obtains the production traceability information of the first object collected by the traceability application;

[0114] The consistency verification module 202 uses a preset consistency rule to perform consistency verification on the production status information and the production traceability information to obtain a consistency verification result;

[0115] The on-chain module 203 uploads the consistency verification result signed by the first business party to the blockchain system;

[0116] The identity verification module 204. The blockchain system obtains the public key of the first business party to verify the identity of the consistency verification result. If the verification passes, it provides the consistency verification result to the requester of the first object.

[0117] In specific implementation, an electric control box can be configured for the sewing machine, and the above-mentioned software modules can be configured in the single-chip microcomputer of the electric control box or in the production management platforms of various manufacturers, so as to realize the combination of traditional manufacturing and the Internet.

[0118] The device collects the production status information of the first device for the first object through sensors, obtains the production traceability information of the first object collected by the traceability application, uses a preset consistency rule to perform consistency verification on the production status information and the production traceability information, and obtains a consistency verification result. The first business party signs and uploads it to the blockchain system. The certificate platform signs the public key of the first business party. The blockchain system obtains the public key of the first business party to authenticate the identity of the consistency verification result. If the verification passes, the consistency verification result is provided to the demander of the first object. By collecting the production status information of the first device for the first object through sensors and combining with a preset consistency rule, the production traceability information can be verified. Since the production status information can prove the actual production situation, the abnormality of the production traceability information can be identified, and thus the scanning operation that does not conform to the rule can be identified.
