Description

Technical Field

[0001] The present invention relates to blockchain technology, and in particular to a method, device, apparatus and computer program product for information management of product manufacturing (for example, product carbon footprint). Background Art

[0002] The Product Carbon Footprint (PCF) is the total greenhouse gas emissions generated by a product, expressed as CO2 equivalents. For products, this includes an analysis of all life cycle stages from raw material extraction and processing, manufacturing, distribution, use and end-of-life disposal. Many companies now use this approach to better understand carbon emissions in their supply chains and identify efficiency opportunities.

[0003] PCF is calculated by estimating CO2 emissions, which may include other greenhouse gas emissions such as nitrous oxide and / or methane. To make the estimate more detailed, in some cases the calculation may also include other types of impacts such as contrails from aircraft engines. The final expression is in terms of carbon dioxide equivalent (CO 2e ), which means that all effects are added together and then expressed in a single form.

[0004] It includes factory emissions and supplier emissions. Factory emissions include direct emissions, such as the combustion of fossil fuels, emissions from chemical and physical processes, etc.; and indirect emissions, such as external providers of electricity, heat, cooling or steam. Supplier emissions include emissions in the upstream supply chain.

[0005] In the traditional information model, manual operations are always involved in collecting and transmitting raw data. Therefore, misoperation, malicious tampering, and illegal operations are inevitable. Even if human factors are ignored, there are other security issues.

[0006] In order to manage PCF values ​​accurately and reliably, these functions are needed in this system: CIA (Confidentiality, Integrity, Availability), Data Authenticity, and Identity Privacy. Integrity means that there is no data tampering. Data Authenticity means that the data is reliable. Identity Privacy means the protection of the identity of the supplier, for example, providing material emissions without revealing the supplier. Confidentiality means protecting the emission data, and only the intended person can view the real data. Availability means making the system more functional.

[0007] There are solutions that use decentralized identity (DID) blockchain and verifiable credentials (VC) to manage PCF data. The DID blockchain here is mainly used for VC verification. PCF data will not be submitted to the blockchain.

[0008] There are solutions that use standard blockchains (e.g., Fabric) to support data integrity and traceability at the micro level (e.g., individual products). The blockchain here is used to store PCF information. The PCF or its hash will be submitted to the blockchain. Summary of the invention

[0013] - verifying the carbon emission value of each product in the batch of products by using product manufacturing information to determine that a difference between the carbon emission value of the product and an average carbon emission value of the batch of products is within a threshold.

[0036] In order to make the technical solutions and advantages of the present invention more clear, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. The specific embodiments described herein are only used to illustrate the present invention and are not configured to limit the protection scope of the present invention.

[0037] Figure 1 is a flow chart of a method for information management of product manufacturing according to an embodiment of the present disclosure.

[0038] In step S101, a public key for verifying an average carbon emission value of a batch of products is stored in a first blockchain.

[0039] Here, a batch of products may be 1000 products manufactured in May with serial numbers 1 to 1000.

[0040] In step S102, a hash value of the carbon emission value of each product in the batch of products is stored in a second blockchain.

[0041] Here it records the carbon emission value of each product of this batch. The gas can be carbon or CO2.

[0042] In step S103, the carbon emission value of each product in the batch of products is verified by using product manufacturing information, thereby determining that the difference between the carbon emission value of the product and the average carbon emission value of the batch of products is within a threshold.

[0043] Here, the product manufacturing information may be a serial number or a manufacturing date. For example, the threshold value may be 2.

[0044] In summary, through the above method, the information management of product manufacturing regarding gas emissions is more accurate and reliable compared to the prior art.

[0045] In another embodiment, the first blockchain is a decentralized identity (DID) blockchain; and the second blockchain is a standard blockchain.

[0046] DID blockchain is a decentralized identity blockchain. The standard blockchain is the Hyperledger-Fabric blockchain (also known as the Fabric blockchain). The Fabric blockchain stores and provides the PCF hashes of factory materials.

[0047] Next, how to determine the threshold value will be described.

[0048] To calculate the threshold, the serial number or the manufacturing date can be used to obtain the threshold. In one embodiment, the method includes calculating the threshold based on the serial number or the manufacturing date of the product. For example, the serial number can be 0001-1000, and the manufacturing date of the product can be May.

[0049] In order to better understand the method, a specific description is given. The carbon emission value of a normal product is 10, and the carbon emission value of an abnormal product is 8. The average value of production can be calculated as 10 by adding the carbon emission values ​​of each product with a serial number within 0001-1000 and manufactured in May. Then, it can be concluded that the difference in carbon emission values ​​of normal products is 0, and the difference in carbon emission values ​​of abnormal products is 2. Therefore, the threshold is set to 2.

[0050] The method may have optional steps. In step S104, a verifiable expression of a batch of products associated with a carbon emission value is created by packaging a verifiable credential of the batch of products provided by a certifier to protect the identity privacy of the batch of products; and the verifiable expression is verified by a public key stored in the first blockchain.

[0051] Through the above steps, the carbon emission value of the product can be ensured to be more reliable and identity privacy can be protected.
