[0037] Any disclosures, embodiments, and examples described herein relate to the methods, systems, apparatuses, products (particularly chemical products), and computer elements listed above and below. Advantageously, the benefits provided by any embodiment and example also apply to all other embodiments and examples. Example

[0038] The public, regulators, and financial investors are increasingly concerned about the environmental impact of chemical production processes. Consequently, major companies have announced ambitious plans to track and manage the environmental impact associated with their product manufacturing. Transparency among stakeholders can help improve compliance with applicable standards (which, in the case of sustainability-related standards, can improve environmental impact). However, the monitoring and sharing of standard certificates is hampered by a lack of common data standards and trusted data platforms. Value chains are long and global, involving many different types of stakeholders. There is a need to simplify data standards related to tracking and sharing standard certificates to enable secure exchange across the chemical manufacturing value chain.

[0039] Several factors can hinder the monitoring and sharing of standard certifications. For example, transparency can be impeded when stakeholders lack access to information about the audit process and results. Furthermore, verification mechanisms may be limited and unable to support the accuracy and reliability of data during the certification process, potentially leading to errors and inaccuracies. In some cases, international harmonization may be hampered by a lack of interoperability between certification systems.

[0040] The systems, methods, and apparatus disclosed herein enable greater transparency in the monitoring and sharing of standard certificates and related information.

[0041] The use of digital certificates can support greater transparency by providing an immutable record of certification (e.g., in monitoring and sharing standard certificates), which improves the accuracy and reliability of certification data. This enhances transparency and trust in the certification system among stakeholders, as they can access and verify certification data in real time. Digital certificates also provide a traceable record of the certification process, helping stakeholders track the origin and flow of certified products. This further enhances transparency and credibility among stakeholders, as they can trace certified products and verify their sustainability claims.

[0042] Digital certificates can provide a platform for data analytics, helping stakeholders analyze and visualize authentication data in real time. This can improve transparency among stakeholders and the efficiency of the authentication system, as stakeholders can use data analytics to identify trends and patterns in authentication data and make informed decisions based on that data.

[0043] The systems, methods, and apparatus disclosed herein enable improved interoperability for monitoring and sharing standard certificates and related information. Digital certificates can be designed to interoperate with other authentication schemes, which can improve the comparability and efficiency of authentication systems among stakeholders. This can enhance the transparency and efficiency of authentication systems because stakeholders can use a common language and data structures to transmit and verify authentication data.

[0044] The systems, methods, and apparatus disclosed herein enable improved verification for monitoring and sharing standard certificates and related information. For example, digital certificates may include digital signatures that provide tamper-proof and verifiable records of authentication data. This can improve verification processes among stakeholders, as they can easily verify the authenticity and integrity of authentication data.

[0045] Digital certificates can also include access controls, which restrict access to authentication data to authorized stakeholders. This improves the security and privacy of authentication data among stakeholders, as they can control who has access to the data. Digital certificates can be designed to allow for real-time verification of authentication data, which can increase the speed and efficiency of the verification process among stakeholders. For example, stakeholders can use digital certificates to quickly verify a product's sustainability claims before making a purchasing decision.

[0046] The following examples will outline embodiments of this disclosure. It should be understood that this disclosure is not limited to the embodiments and / or examples described.

[0047] Digital credentials are digital representations of an entity's (e.g., a company, institution, individual, association, government agency, etc.) certifications, qualifications, performance, or other attributes. For example, a digital credential can represent a certification or other credential issued by a regulatory body, government, industry association, standards-setting organization (SSO), etc. This is a secure and portable way to store and share information about an entity's attributes. Digital credentials can take various forms, such as digital badges, certificates, or licenses, and can be issued by institutions, laboratories, government agencies, non-profit associations, regulatory bodies, industry groups, SSOs, etc. Digital credentials may include information such as the credential holder's name, the issuer, the date of issuance, the validity period or expiry date, and the criteria or standards met to obtain the credential. The use of digital credentials allows individuals and companies to securely and verifiably demonstrate their various certifications to consumers, suppliers, regulators, and other upstream and downstream participants in the value chain, which can help create a more transparent and efficient certification system.

[0048] A standard can refer to a set of guidelines, rules, or requirements that establish a common framework or consistent way of working. It can be a formal document that provides specifications, procedures, or guidelines for a product, service, process, or system with the aim of ensuring quality, safety, reliability, interoperability, or other desired characteristics.

[0049] Standards can be developed and maintained by Standards Setting Organizations (SSOs), which can be national, regional, international bodies, or industry alliances. Standards are typically based on consensus reached among stakeholders from industry, government, academia, and other sectors. Standards can be voluntary or mandatory and can be used by governments, businesses, or other organizations as a basis for regulation, procurement, or quality management. Standards can cover a wide range of topics, such as information technology, manufacturing, environmental management, and sustainability. They can be developed for specific industries, products, or processes, or they can be inherently general and applicable to a broad range of applications. A predefined set of rules for terminology can be used to refer to standards. A predefined set of rules for terminology can also be used to refer to standards.

[0050] Sustainability standards can refer to a set of requirements, guidelines, and criteria that define sustainable practices for a specific industry or product. Sustainability standards can be developed by organizations such as REDcert, ISCC, and RSPO, which are responsible for setting the criteria and monitoring the certification process. These organizations can collaborate with stakeholders from industry, civil society, and other sectors to develop standards that promote sustainable practices. Sustainability standards typically cover a wide range of topics, such as land use, biodiversity, greenhouse gas emissions, water management, quality balance, recycling, and circular economy. They can develop specific requirements and indicators for sustainable practices and establish certification processes to verify compliance with these practices.

[0051] A certification system refers to a set of standards and guidelines used to verify the use of standards (e.g., the quality allocation method for allocating sustainable raw materials to sustainable products). Examples of certification systems may include REDcert2 and ISCC+. A certification body is an organization that performs the actual certification process (e.g., applying a certification system to candidate sites, processes, and / or products). A certification body can be an independent third party accredited by the certification system (an accreditation body) to audit, inspect, and issue certificates according to the standards set forth in the scheme.

[0052] Certification bodies can be independent organizations responsible for verifying compliance with sustainability standards. Certification bodies may be authorized by the SSO to audit and inspect companies seeking certification under a particular standard. These bodies may be accredited by a third-party accreditation body to ensure they meet certain criteria of impartiality, professionalism, and reliability. Certification bodies work with companies to assess their compliance with standards (e.g., sustainability standards), which may include requirements related to environmental performance. Certification bodies may assess a company's management systems, processes, and performance metrics to determine if the company meets the requirements of the standard. If the company meets the requirements of the standard, the certification body may issue a certificate indicating that the company (or its premises, processes, or products) meets the requirements of one (or more) standards. Partial compliance may refer to meeting at least some of the requirements of the standard. Certification bodies may also be responsible for ensuring the continued compliance of certified companies through periodic audits and inspections.

[0053] Digital systems can use authentication and / or authorization technologies to control access to resources and verify user identity. Authentication can refer to the process of verifying the identity of a user or system. It can involve presenting credentials (such as usernames and passwords, digital certificates, or biometric samples) and comparing them to records or standards to determine whether a user or system is authorized to access specific resources or perform specific actions. Authorization can refer to the process of granting or denying access to resources or systems based on an authenticated identity and the level of permissions assigned to that identity. It may involve defining roles, rules, or policies that specify which actions or resources a user or system is allowed to access and which actions or resources are restricted or prohibited from accessing them.

[0054] Public and private keys can be used in digital systems to provide secure access to resources and verify user identity. Public and private keys are part of an encryption system known as public-key cryptography. In this system, each user has a pair of keys (a public key and a private key) that are mathematically related but cannot be derived from each other. The public key can be used to encrypt data and is available to others who might want to send encrypted data to the user. The private key can be kept secret and can be used to decrypt data that has been encrypted with the public key.

[0055] Various types of audits can exist, including: on-site audits, remote audits, paper audits, and / or virtual audits. On-site audits can refer to a third party (or consumer) coming to the manufacturing site to perform the audit. Remote audits can be conducted remotely by a third party (or consumer) using a digital platform to hold meetings and collect data and other information. Paper audits may involve (1) the auditor providing a questionnaire to the manufacturer, and (2) the manufacturer completing the questionnaire and returning it to the auditor. Virtual audits can refer to the use of a digital platform that enables auditors to conduct audits remotely. Virtual audits can significantly reduce (or even eliminate) the need for interaction between auditors and plant personnel by using virtual reality and remotely accessible data storage.

[0056] A certificate is a document issued by a certification body indicating that a company (or its premises, location, factory, products, legal entity, etc.) or its products have met the requirements of a certification system. This certificate serves as evidence that the company or its products have been audited by an independent third-party certification body and found to comply with relevant standards and requirements. Certificates typically include information such as the certified company's name and address, the scope of certification (e.g., which products or processes are covered), the name of the certification body, the date of issuance, and the expiration date. Certificates are usually valid for a specific period and may require ongoing audits or surveillance to maintain. This certificate is an important marketing tool for certified companies because it demonstrates a commitment to quality and compliance with industry standards.

[0057] A digital identifier is a unique code or set of characters assigned to a specific entity (such as an individual, organization, or resource) to distinguish it from other entities. Digital identifiers can serve as tags or handles that enable digital systems to identify and track entities across different contexts and applications. They can be used to retrieve or link to digital resources, such as data, documents, images, videos, or web pages, and to manage access to or permissions for these resources. Digital identifiers can take various forms, such as email addresses, usernames, domain names, IP addresses, or digital certificates. They can be assigned by different organizations or institutions (such as domain registrars, social media platforms, or government agencies) and can be used for different purposes, such as authentication, authorization, or identification. The use of digital identifiers enables efficient and secure communication and data exchange between different entities.

[0058] Digital proofs can refer to verifiable evidence of the authenticity of digital credentials without revealing the underlying encryption mechanisms of the data. Digital proofs can be generated by combining digital credentials with cryptographic proofs (such as digital signatures or zero-knowledge proofs) to create tamper-proof, cryptographically secure records that can be shared with others. Digital proofs may include metadata about the credential (such as the issuer, credential holder, issuance date, and other relevant information) and a cryptographic signature verifying the integrity of the data.

[0059] A network node can refer to a device or computer connected to a network and capable of sending, receiving, or forwarding data. A network node is any type of device connected to a network, such as a server, router, switch, mobile device, IoT device, or personal computer. In the context of a digital credential scheme, each entity (e.g., issuer, holder, and verifier) ​​can have its own network node, which allows it to interact with a distributed ledger storing digital credentials. Network nodes can communicate with each other to ensure the integrity and security of the system and facilitate the exchange of digital credentials between different entities.

[0060] Material composition data can refer to information about the chemical and physical properties of a material, including the elements and compounds that constitute the material, their proportions, and any impurities or additives present. Material composition data can include information about the elements and compounds that constitute the material. It can include information about elemental composition, chemical structure, impurities, isotopic composition, chemical properties, and / or chemical formulas. It can include characteristics such as density, melting point, thermal conductivity, and electrical conductivity. It can include mechanical properties such as tensile strength, yield strength, and hardness. It can include environmental properties such as corrosion resistance, weather resistance, and flammability. It can include information about any regulations or standards that the material must comply with. Material composition data can include information about the identity, quantity, source, and nature of the chemical substances that constitute the material, as well as information about any impurities or contaminants that may be present. Material composition data can include data indicating the types of carbon (e.g., biogenic carbon, fossil carbon, their fractional proportions, etc.) in the material.

[0061] Elemental composition data can refer to information about the types and amounts of chemical elements present in a substance. Molecular composition data can refer to information about the structure, composition, and properties of molecules, and may include, for example, chemical formulas describing the types and numbers of atoms in the molecule, as well as information about the arrangement of those atoms and the bonds between them. Recycled content data can refer to information about the amount and type of recycled materials used in a product or material. Recycled content data may include the percentage of recycled materials used in the product or material and / or the source of the recycled materials. Restricted materials data can refer to information about chemicals or substances restricted by law or regulation. This data may include information about the specific restricted substance, the reason for the restriction, and any applicable regulations or standards.

[0062] Raw data can refer to data collected directly from its source through methods such as sensors (e.g., temperature, motion, current, voltage, and / or GPS sensors), cameras, satellites, network monitoring tools, log analysis tools, packet capture tools, etc.

[0063] Raw data can take many forms, including numerical data, text data, audio recordings, video recordings, or images. Depending on the specific context and research question, a wide variety of methods and techniques can be used to collect raw data. Raw data is generally considered more accurate and reliable than secondary data, which is data previously collected or analyzed by others. The term supplementary raw data refers to any raw data that can be used as additional supporting information for digital credentials.

[0064] A carbon footprint, or product carbon footprint (PCF), can refer to the amount of greenhouse gases (GHGs) emitted or removed during the production process at a manufacturing facility, expressed in carbon dioxide equivalents. PCF can be assessed from cradle to gate (partial PCF) or cradle to grave (total PCF).

[0065] (Multiple) environmental characteristics can specify or quantify ecological criteria associated with the environmental impact of a product. (Multiple) environmental characteristics can be generated or obtained from measurements taken during the life cycle of one or more products. Environmental characteristics can be determined at any stage of the product life cycle and can characterize the product's environmental impact during or up to that stage. (Multiple) environmental characteristics can include, for example, impact categories such as fossil footprint, carbon footprint, greenhouse gas emissions or global warming potential, primary energy demand, cumulative energy demand, consumption of biological and non-biological resources, air emissions, stratospheric ozone depletion potential, ozone formation, land and / or ocean acidification, water consumption, water loss, water availability, water pollution, noise pollution, freshwater and / or ocean eutrophication potential, human carcinogenic and / or non-carcinogenic toxicity, photochemical oxidant formation, particulate matter formation, terrestrial, freshwater and / or marine ecotoxicity, ionizing radiation, agricultural and / or urban land occupation, land conversion, land use, indirect land use, deforestation, biodiversity, mineral resource consumption, fossil resource consumption and / or raw material demand (e.g., sustainable raw material demand and / or fossil raw material demand).

[0066] Multiple environmental characteristics can be calculated by combining one or more environmental characteristics. Multiple environmental characteristics may include, for example, product or material characteristics related to the production of the product or material, such as renewable, bio-based, vegetarian, halal, kosher, palm oil-free, natural, etc.

[0103] This disclosure pertains to the field of computer-implemented systems and methods for generating and transmitting digital credentials representing at least partial compliance with standards. For example, when applying standards certification to products manufactured in a chemical production process at a chemical plant, the disclosed systems and methods can enhance transparency, verification, and interoperability among stakeholders.

[0104] The disclosed systems and processes can be applied to a wide variety of products made from input materials, such as chemical products or precursor products. The term "product" can refer to any good that can be sold to others at any point in the value chain. This can include final products for end users (e.g., automobiles, paint, toys, or pharmaceuticals). It can also include goods that are typically sold to other companies for further processing (e.g., steel parts for machinery, plastic granules for extrusion, or compounds such as acrylic acid used to manufacture superabsorbent polymers for diapers). It can also include goods very early in the value chain, such as crude oil fractions (e.g., naphtha), agricultural products (e.g., soybeans), or pure sand used in glass production.

[0105] Figures 1a to 1c Examples of chemical processes with multiple inputs and multiple outputs are shown.

[0106] A chemical process may include different process steps for producing one or more output materials from one or more input materials. A chemical process may include at least one process step involving at least one chemical reaction. A chemical process may produce multiple output materials from multiple input materials. Chemical process steps include, for example, oxidation, reduction, hydrogenation, dehydrogenation, hydrolysis, hydration, dehydration, halogenation, nitration, sulfonation, amination, alkylation, dealkylation, esterification, polymerization, polycondensation, catalysis, fermentation, mixing, separation, purification, etc. These process steps may be performed sequentially in time and / or space to chemically transform input materials into output materials.

[0107] Figure 1aInput materials 102 and 104 are shown being fed into chemical process 100. Input materials 102 and 104 are chemically processed into output materials 106 and 108. Output materials 106 and 108 may include a primary product and at least one byproduct. In chemical reactions, the yield of an output material is typically less than 100% due to side reactions and losses during purification. Therefore, chemical processes can produce multiple output materials. The primary product may represent the product of interest, and the byproduct may represent additional output products inevitably obtained through the chemical process. Byproducts may be intermediates that can be used as reagents in another chemical process. The chemical process, including the input materials and the production quantities of output materials, can be monitored by a sensor 110 that provides production monitoring data.

[0108] Figure 1b The input materials 102, 103, and 104 are shown being fed into chemical process 100. The input materials 102, 103, and 104 are chemically processed into output materials 106 and 108, as shown in... Figure 1a As described in the context. In addition to output materials 106 and 108, the chemical process may also produce waste stream 112. The waste stream may include any output materials that cannot be used as reagents in another chemical process.

[0109] Figure 1c The input materials 102 and 104 are shown being fed into chemical process 100. The input materials 102 and 104 are chemically processed into output materials 106 and 108, as shown in... Figure 1a and Figure 1b As described in the context. In addition to output materials 106 and 108, the chemical process can also produce a refeed stream of input material 114 and reuse it.

[0110] Figure 2 It showcases a chemical production network that includes multiple chemical processes.

[0111] Figure 2This illustrates the networked nature of a chemical production network. Multiple chemical processes are interconnected via their input-output material relationships. For example, output materials 206 and 208 of chemical process 204 can be input materials for chemical processes 214 and 216. Chemical process 214 can produce output materials 218 and 220 and waste stream 222 from input materials 210 and 206. Output material 218 can leave the chemical production network as a final product. Input material 210 can be fed into chemical process 214 from outside the chemical production network. Input material 206 can be fed into chemical process 214 from chemical process 204 within the chemical production network. Similarly, chemical process 216 can produce output materials 224 to 230 from input materials 208 and 212. Output materials 228 and 230 can leave the chemical production network as final products. Chemical process 232 can produce output materials 234 and 236 from input materials 222, 224, and 226. Output materials 234 and 236 can leave the chemical production network as final products. In this way, the chemical production network can use interconnected or related chemical processes to produce output products leaving the network. Interconnected or related processes may include at least one intermediate of one chemical process being used as input material for one or more downstream chemical processes.

[0112] Figure 3 It showcases a sub-cluster of a chemical production network that includes multiple chemical processes.

[0113] The chemical production network may include multiple plants that perform chemical processes 312, 310, and 318 and form a sub-cluster 300 of the chemical production network. Input materials 302 and 304 may be fed into chemical process 310. Input materials 306 and 308 may be fed into chemical process 312. Output materials 320 and 324 may be provided as the final products of sub-cluster 300 and leave sub-cluster 300. Output materials 314 and 316 of chemical processes 310 and 312 may be provided as input materials to chemical process 318. Output materials 322 and 326 may be provided as the final products of sub-cluster 300 and leave sub-cluster 300.

[0114] Figure 4 It shows multiple sub-clusters that form a chemical production network.

[0115] The chemical production network 400 may include multiple sub-clusters 410, 412, and 422. Input materials 402, 404, 406, and 408 can be fed into sub-clusters 410 and 412. Output material 416 from sub-cluster 410 and output material 418 from sub-cluster 412 can be fed into sub-cluster 422 as input materials. Additionally, input material 414 can enter the chemical production network 400 and be fed into sub-cluster 422. Output materials 424, 426, and 428 can leave the chemical production network as final products.

[0116] As shown in Figure 1 to Figure 4 As shown, the chemical production network 400 may include multiple chemical processes 100, which may be arranged in sub-clusters 410, 412, and 422. The chemical processes 100 or sub-clusters 410, 412, and 422 may be connected to form a network with multiple production chains interconnected via their material flows. The chemical production network may form part of a discrete product supply chain, wherein the discrete product is produced from one or more chemical outputs or output materials provided by the chemical production network.

[0117] Figure 5 This is a flowchart illustrating selected aspects of transmitting digital credentials with material composition data according to embodiments of this disclosure.

[0118] This disclosure includes the step (510) of selecting a digital credential that represents at least partial compliance with the standards, wherein the digital credential includes a digital identifier associated with the certification authority (such as...). Figure 5 (As shown). In an embodiment, the digital system may present the user with available certificates along with any relevant metadata, such as the issuer (e.g., via a text and / or graphical user interface) and / or the expiration date. The user can then select the desired certificate from the available options and instruct the digital system to use it for the current interaction. The selection process may involve additional steps such as verifying the user's identity, checking the validity and status of the selected certificate, and establishing a secure connection with the intended recipient or service provider.

[0119] In some embodiments, the digital credential may be a verifiable credential, and the digital identifier may be a decentralized identifier (DID). Figure 6This is a block diagram illustrating selected aspects of a digital system using verifiable credentials with material composition data, according to embodiments of this disclosure. Issuer 610 may be a network node of an entity that issues verifiable credentials to another entity (e.g., a company, institution, or individual, association, government agency, etc.). Issuer 610 may be associated with a certification authority, SSO, auditor, regulatory body (or other government entity), or any other organization authorized to issue credentials. Issuer 610 may create verifiable credential 612, which may contain information about holder 620. Holder 620 is a network node of an entity (e.g., a company, institution, or individual, association, government agency, etc.) that receives and holds verifiable credential 612. Holder 620 may control its credentials and may share these credentials with others (e.g., with verifier 630). In some embodiments, verifiable credential 612 is a digital representation of a certificate that conforms (at least partially) to standards. Verifier 630 is a network node of an entity that can decide to verify the authenticity of verifiable credential 612. References below Figure 9 The verification process will be described further.

[0120] Verifiable credentials 612 may include, for example: Figure 7A One or more statements 614 are shown. In an embodiment, a statement may refer to a data element contained within a credential 612. Each statement may represent a credential holder (e.g., holder 620, such as...). Figure 6 The specific attributes or characteristics (as shown). In some embodiments, the verifiable certificate 612 represents a certificate issued by a certification body. Statements that may be included in the verifiable certificate 612 may depend on (multiple) standards and / or certification bodies. Examples of the types of statements that may be included in the verifiable certificate 612 may include: the name of the certification body or organization 614a, the name of the standard or certification scheme 614b, the name of the certified company or individual 614c, the certification date or expiry date 614d, the scope of the specific product or service certified or certified 614e, the certification identification number or code 614f, the results of any tests or inspections conducted as part of the certification process 614g, any relevant environmental or sustainability metrics or indicators 614h, and / or the level or grade of conformity achieved 614i. In alternative embodiments, the verifiable certificate 612 may have more statements, fewer statements, and / or different statements. Statements 614 may be structured as key-value pairs, where the key represents the name of the attribute and the value represents the actual information. For example, a claim for an authentication scheme could have a key named "Authentication Scheme" and a value named "123456789". The issuer 610 can digitally sign claims 614a to 614i using an encryption key to ensure their integrity and authenticity. In an embodiment, claims 614a to 614i may be selectively disclosed to different parties depending on the needs of the holder 620 and the requirements of the verifier 630.

[0121] The decentralized identity service 640 may be a platform or network providing services for managing and exchanging decentralized identities and verifiable credentials. In embodiments, the decentralized identity service 640 may provide identity creation and management, as well as identity registration. In some embodiments, the decentralized identity service 640 may create decentralized identifiers (DIDs) for issuers 610, holders 620, and / or verifiers 630. A DID may be a unique identifier used to represent a digital identity on a decentralized network. In some embodiments, a DID may be used to link verifiable credentials to the holder's digital identity. A DID may serve as a reference to the holder's public key, which is used to sign and verify verifiable credentials.

[0122] Decentralized network 650 can be a digital network designed to operate in a distributed and decentralized manner without relying on any central authority or intermediary. In some embodiments, decentralized network 650 is a distributed ledger. A distributed ledger refers to a type of database maintained by a computer network rather than a central authority. The ledger records transactions between participants in the network, and these transactions are stored in a tamper-proof and immutable manner. Decentralized network 650 can be based on blockchain technology, which uses cryptographic algorithms to ensure the security and integrity of transactions recorded on the ledger. These algorithms ensure that the ledger cannot be altered or tampered with without the knowledge of the parties involved, and that all participants in the network can verify the authenticity of transactions. Decentralized network 650 can be used to store and manage the credentials themselves, as well as associated metadata, such as the identity of the issuer 610 and the date of issuance. This provides a secure and tamper-proof record of credentials that can be verified by anyone with access to, for example, the ledger.

[0123] In some embodiments, the issuer 610 may create and digitally sign a verifiable credential 612 by: (i) creating a DID using, for example, a decentralized identity service 640; (ii) generating a public / private key pair associated with the DID; (iii) creating a verifiable credential that includes information about the holder 620, the credential itself, and the issuer 610; (iv) signing the verifiable credential 612 with the private key; (v) attaching the DID to the verifiable credential 612 to indicate that the issuer 610 is issuing the verifiable credential 612; (vi) transmitting the verifiable credential 612 to the holder 620; and (vi) publishing the verifiable credential 612 to a decentralized network 650.

[0124] In some embodiments, holder 620 may store verifiable credentials 612 in a digital wallet 625. Digital wallet 625 may be a digital application that allows holder 620 to store, manage, and present digital certificates from one or more issuers (e.g., issuer 610). Digital wallet 625 may include a user interface that displays digital certificates and allows holder 620 to view and manage these certificates. The wallet may also include features such as search functionality, filtering options, and the ability to categorize certificates by issuer, date, or other criteria. Digital wallet 625 may be stored on holder 620's network node, system, device (such as a smartphone or computer), or in the cloud, and may be protected with passwords or other forms of authentication to ensure that only the holder can access the certificates. Digital wallet 625 may also include features for presenting and sharing certificates with others. For example, holder 620 may be able to generate QR codes or share links that allow others to view the certificates, or the wallet may include integration with other applications or platforms that require verification of the holder's credentials.

[0125] Holder 620 can prepare and present verifiable credential 612 to verifier 630 through the following process: (i) selecting verifiable credential 612 from wallet 625, (ii) generating a digital proof using, for example, the holder 620's private key and the DID associated with verifiable credential 612, and (iii) transmitting the verifiable credential 612, the digital proof, and the DID associated with the verifiable credential to verifier 630. Verifier 630 can then use the digital proof and the DID associated with verifiable credential 612 to verify the authenticity and validity of verifiable credential 612.

[0126] In some embodiments, holder 620 may collect material composition data to provide supporting information for verifiable certificate 612. The material composition data can provide context for the verifiable certificate, thereby helping verifier 630 understand the verifiable certificate 612 in a broader context. For example, if the verifiable certificate 612 shows (at least partially) compliance with standards, holder 620 may provide material composition data from an audit to help verifier 630 understand the certificate in the context of the audit process. The material composition data can also increase verifier 630's reliance and confidence in holder 620 (and the verifiable certificate 612). For example, holder 620 may provide additional information about the quality of its data to increase reliance on the verifiable certificate 612. The material composition data can also help holder 620 meet additional requirements or criteria necessary for verifier 630 to accept the verifiable certificate. For example, if verifier 630 requires specific data on GHG emissions, holder 620 may provide carbon emission-related material composition data along with the verifiable certificate 612. Material composition data can also provide evidence to support the verifiable certificate 612 and the claims made therein. For example, if the verifiable certificate 612 relates to standards specifying how materials are produced or processed, the holder 620 can provide material composition data in the form of photographs documenting their production and processing practices.

[0127] Figure 7BAn example of material composition data 616 with raw data element 618 is shown. In embodiments, material composition data 616 may include one or more raw data elements 618a to 618k. Each raw data element may provide supporting information for a verifiable certificate 612, including, for example, a statement 614 of the verifiable certificate 612. In some embodiments, the verifiable certificate 612 represents a certificate issued by a certification body. The raw data elements that may be included in material composition data 616 may depend on standards(s) and / or certification bodies(s). Examples of types of raw data elements that may be included in material composition data 616 may include: molecular composition data (618a), elemental composition data (618b), recycled content data (618c), restricted material data (618d), compound data (618e), chemical property data (618f), chemical structure data (618g), impurity data (618h), biogenic carbon data (618i), social metadata (618j), and / or institutional metadata (618k). The original data element 618 can be structured as key-value pairs, where the key represents the name of the attribute and the value represents the actual information. For example, the original data element of image data could have the key "image" and the value "987654321". The issuer 610 can digitally sign the original data elements 618a to 618k using an encryption key to ensure their integrity and authenticity. In embodiments, claims 618a to 618ki can be selectively disclosed to different parties depending on the needs of the holder 620 and the requirements of the verifier 630.

[0128] Figure 8 This is a block diagram illustrating selected aspects of presenting a digital certificate with material composition data according to an embodiment of the present invention. System 800 includes a decentralized network 650 having an issuer 610, a holder 620, and a verifier 630 (see above). Figure 6 (Description in more detail). Issuer 610 issues digital certificate 612 to holder 620. Holder 620 stores digital certificate 612 in digital wallet 625. In the illustrated embodiment, digital wallet 625 may be part of production operating system 810. Production operating system 810 may monitor and / or control the production network.

[0129] In this embodiment, the material composition data collection system 820 is communicatively coupled to the production operating system 820 via a digital network (e.g., any combination of wired and / or wireless networks suitable for exchanging digital data). The material composition data collection system 820 includes data sources 820a to 820d. Data sources 820a to 820d can be systems from which data can be retrieved or obtained. Data sources can be any type of system or technology that collects, stores, and / or provides access to data, such as databases, file systems, web services, sensor networks, cameras, satellites, IoT devices, production equipment, etc. Applications or other systems within the production system 810 can access the material composition data 814, for example, through a query interface or through data transfer mechanisms such as File Transfer Protocol (FTP), web API, and / or message queues. Depending on the specific context and use case, data sources 820a to 820d can be internal or external to the system. For example, a data source can be an internal database used by applications to store and retrieve data, or an external web service that provides data to third-party applications.

[0130] In some embodiments, digital credential presentation logic 816 can generate a data probate score for some or all of the material composition data collected from data sources 820a to 820d. Data probate refers to the history and origin of data and may include the creation, modification, and processing of data over time. The data probate score can be used to assess the reliability and credibility of data based on data probate information. The score can be based on a range of factors, such as the data source, the methods used to collect and process the data, and the quality and completeness of the metadata associated with the data.

[0131] Data traceability scores can be used as a numerical indicator of the reliability of material composition data, providing a quantitative measure of data reliability and accuracy. By using data traceability scores, stakeholders can make more informed decisions regarding the material composition data associated with digital credentials.

[0132] In some embodiments, feedback received from other users / systems may be applied to help generate a data source sourcing score. This feedback may be referred to as metadata. Metadata refers to data that provides information about other data. In the context of data source sourcing, metadata may include information about the data source, the methods used to collect and process the data, and any other relevant information that can help establish the reliability and credibility of the material composition data. Metadata may be generated by other users or systems that have already interacted with the data, or it may be generated by the data repository or database itself (e.g., by data sources 820a to 820d). Metadata can be used to supplement the material composition data and provide additional context and information that can help improve the accuracy and reliability of the material composition data.

[0133] In some embodiments, system 810 can automatically analyze the metadata it receives to generate a data source traceability score, the output of which may be referred to as a "metadata profile." A metadata profile can be a structured representation of metadata associated with a specific dataset or data resource. It may include information about the data's origin, history, and processing, as well as any other relevant information that can help establish data credibility and reliability. The metadata profile can be automatically generated by system 810 using algorithms and machine learning techniques to analyze the metadata and identify patterns or trends. The metadata profile can then be used to generate a data source traceability score, which provides a quantitative measure of the reliability and accuracy of the data.

[0134] When generating metadata profiles, metadata from crowdsourcing (such as from consumers or user reviews) can be referred to as "social metadata." Social metadata refers to metadata generated by users or consumers that is not generated by the data repository or database itself. This can include information such as user ratings, reviews, comments, or tags, and can provide valuable insights into the quality, relevance, and usefulness of the data. Social metadata can supplement existing metadata and provide additional context and information that can help improve the accuracy and relevance of the metadata profile. Social metadata can also be used to enhance the user experience by providing more personalized and relevant recommendations or search results based on user preferences and behaviors.

[0135] When generating metadata profiles, metadata from public records or records from nonprofit associations can be referred to as "institutional metadata." Institutional metadata refers to metadata generated by an institution or organization (such as a government agency, nonprofit association, or academic institution). This can include information such as publication records, grants, research data, or other institutional records. Institutional metadata can supplement existing metadata and provide additional context and information that can help improve the accuracy and relevance of the metadata profile. Institutional metadata can also be used to improve the credibility and reliability of data by providing a trusted source of information about the data's origin and history.

[0136] Digital credential presentation logic 816 generates a presentation by holder 620. Presentation refers to the digital process in which holder 620 presents digital credential 612 and material composition data 814 to verifier 630 to prove (or support) a specific claim or attribute. Presentation may involve holder 620 generating a digital certificate or signature confirming the authenticity and integrity of digital credential 612 and material composition data 814. Holder 620 can then securely and verifiably present digital credential 612, material composition data 814, and digital certificate to verifier 630 (as shown in 830). Material composition data 814 may include additional claims, contextual information, or other relevant data that helps verify the authenticity and validity of verifiable credential 612. For example, if verifiable credential 612 indicates that holder 620 (at least partially) conforms to a standard, the material composition data may be, for example, CO2 data directly from sensors, production data, additional proof points, etc. The presentation process allows for secure and selective disclosure of data and attributes while preserving holder 620's privacy and control.

[0137] Let's refer to it again. Figure 5 and Figure 6 Holder 620 can use their private key to generate a digital proof that they are presenting as a digital credential indicating at least partial compliance with standards. In some embodiments, issuer 610 may be a network node of a certification authority (such as REDcert2, ISCC+, RSPO, etc.). Verifiable credential 612 may include one or more claims 614 indicating that issuer 610 has certified holder 620 as (at least partially) compliant with one or more standards. In some embodiments, holder 620 may store verifiable credential 612 in a digital wallet 625. Holder 620 may (e.g., via a user interface) receive instructions to present (i.e., share) verifiable credential 612 (or one or more claims 614) to, for example, a verifier 630. Holder 620 may use their private key and the DID associated with verifiable credential 612 to generate the digital proof. In alternative embodiments, holder 620 may use different digital signature mechanisms (such as zero-knowledge proof (ZKP), OpenPGP, JSON Web Token (JWT), or JSON Web Signature (JWS)) to generate the digital proof.

[0138] This disclosure includes the steps (520) for selecting a digital representation of the material composition data associated with the standard (e.g., Figure 5 (As shown). In an embodiment, the digital system may present the user with available material composition data, as well as any associated metadata, such as data type (e.g., via text and / or graphical user interface) and / or material composition data (and / or the raw data elements therein, e.g., Figure 7BThe description (618a to 618k) is then used. The user can then select the desired material composition data (and / or raw data elements) from the available options and instruct the digital system to use it for the current interaction. The selection process may involve additional steps such as verifying the user's identity, checking the validity and status of the selected certificate, and establishing a secure connection with the intended recipient or service provider.

[0139] Holder 620 can then use its private key to generate digital proof that holder 620 is presenting the following: (i) a digital credential representing at least partial compliance with the standard and / or (ii) a digital representation of the material composition data associated with the standard (in Figure 5 (iii) Applicable digital proofs. Holder 620 may (e.g., via a user interface) receive instructions to present (i.e., share with) verifiable credential 612 (or one or more claims 614) and material composition data 616 (or one or more raw data elements 618) to, for example, a verifier 630. Holder 620 may generate digital proofs using its private key and the DID associated with verifiable credential 612. Alternatively, holder 620 may generate separate digital proofs for each of verifiable credential 612 and material composition data 616 using the DIDs associated with verifiable credential 612 and material composition data 616, respectively. In alternative embodiments, holder 620 may generate digital proofs using different digital signature mechanisms, such as zero-knowledge proofs (ZKP), OpenPGP, JSON Web Tokens (JWT), or JSON Web Signatures (JWS).

[0140] Figure 9 This is a timing diagram illustrating selected aspects of the interaction between network nodes according to an embodiment of the present invention. Issuer 610 creates a verifiable credential at 905 and provides it to holder 620 at 910. Issuer 610 can create the verifiable credential by: aggregating the data to be included in the credential, according to a data model (e.g., such as...). Figure 7AThe credential (as shown) is formatted and signed using its private key. In some embodiments, the issuer 610 may send the verifiable credential as a JSON-LD document. The JSON-LD document is a machine-readable format containing information about the verifiable credential, such as the issuer's name, credential type, holder's name, and expiration date. The issuer 610 may digitally sign the JSON-LD document to support the integrity and authenticity of the information contained therein. Once the JSON-LD document is signed, it can be transmitted to the holder 620 using any secure communication method, such as email or a secure messaging service. The holder 620 can then store the credential in a digital wallet or other applications designed to manage verifiable credentials.

[0141] Holder 620 can use a verifiable credential to create one or more claims, as shown in 915. In some embodiments, holder 620 can extract relevant information (for one or more claims) from the verifiable credential and create a JSON-LD document containing the claims(s) and other contextual information (such as the verification method to be used). Holder 620 can also create material composition data (e.g., associated with the verifiable credential), as shown in 920. Holder 620 can obtain this data from a data source containing additional verifiable data (e.g., from a source such as...). Figure 8 The holder 620 can extract relevant information from the digital wallet 625 (shown) to create material composition data. The holder 620 can add the material composition data to a JSON-LD document containing the claim(s). Alternatively, the holder 620 can add the material composition data to a separate JSON-LD document (or use a different format for the material composition data).

[0142] Let's refer to each other. Figure 5 and Figure 9 Holder 620 may transmit the digital credential, a digital representation of the material composition data, and a digital proof that the holder is presenting the digital credential to verifier 630 (e.g., to provide a digital representation that at least partially conforms to standards). For example, holder 620 may use its own cryptographic signature to sign (multiple) JSON-LD documents containing verifiable credentials and material composition data. Holder 620 may then transmit the signed JSON-LD documents to verifier 630 via any combination of wired and wireless networks (and applicable protocols for wired and / or wireless networks) (e.g., ...). Figure 9 (as shown in 535). For example, in an embodiment, the holder 620 can transmit the signed JSON-LD document via any secure communication method, such as email or a secure messaging service.

[0143] Verifier 630 can verify the cryptographic signature of the JSON-LD document, as shown in 930-935. For example, verifier 630 can check the DIDs of issuer 610 and holder 620, as shown in 930. Then, at 935, verifier 630 can verify multiple signatures on the JSON-LD document(s). In some embodiments, verifier 630 also checks whether the verifiable credentials (and / or material composition data) are still valid.

[0144] Figure 10 Examples of methods or apparatus for providing digital credentials and / or material composition data associated with chemical products to data consumers (e.g., consumers) via decentralized networks are illustrated.

[0145] Such as by chemical production networks (e.g., Figure 4 The chemical products 272 produced by the chemical production network 400 shown can be provided in association with digital assets (such as digital credentials and / or material composition data), as in... Figures 5 to 10 As described in the context of [the document / description]. Digital assets may include chemical product identifiers. Digital assets may include one or more digital credentials, such as verifiable credentials, indicating that chemical product 272 is certified as (at least partially) conforming to one or more standards. Examples of standards under certification include, but are not limited to: International Sustainability and Carbon Certification (ISCC), RedCert certification, Roundtable on Sustainable Palm Oil (RSPO) certification, etc. Digital assets may include digital credentials and / or material composition data associated with the credentials. Digital assets may include digital representations of one or more certificates showing at least partial conformity to one or more standards. Digital assets may also include digital representations of material composition data associated with one or more certificates.

[0146] Digital assets may further include or involve authentication and / or authorization information linked to digital representations of chemical product identifiers, digital credentials, and / or material composition data. Authentication and / or authorization information may be provided for authenticating and / or authorizing data service 1008 and / or data consumption service 1010. Chemical product identifiers may include or involve decentralized identifiers uniquely associated with the chemical product (and / or digital credentials and / or digital representations of material composition data). Decentralized identifiers may be linked to digital credentials and / or digital representations of material composition data. Digital representations may include representations for accessing digital credentials or portions thereof.

[0147] Decentralized identifiers can include Universally Unique Identifiers (UUIDs) or Digital Identifiers (DIDs). A decentralized identifier can include any unique identifier that is uniquely associated with the data owner and / or the chemical product. The data owner can be the producer of the chemical product. Through the decentralized identifier and its unique association with the data owner and / or the chemical product, the data owner can control access to the digital representation of the digital credentials and / or the material composition data.

[0148] Digital assets, including digital credentials and / or material composition data, can be stored in a decentralized database 1000. One or more digital credentials and / or material composition data can be stored in a database 1002 associated with the data owner (such as the producer of chemical product 272).

[0149] Chemical product 272 can be physically delivered to a consumer (or other user of the chemical product). The chemical product can be linked to a QR code that has been encoded with a chemical product identifier. The user of the chemical product can read the QR code using a QR code reader 1006. The chemical product identifier can be provided to a database 1024 associated with the user or consumer of chemical product 272.
