Blockchain-based Document Distribution
Leveraging the HyperLedger blockchain platform, the LEDGEr-based Network for Document Distribution (LEDGENDD) solution promotes effective document and data publication and sharing within the Defense Research, Development, Test and Evaluation (RDT&E) community. In addition to high availability and confidentiality, LEDGENDD enables easy document authentication and integrity verification, traceable document delivery, and fine-grained access control beyond initial dissemination. It addresses unique challenge of integrating blockchains with Defense Technical Information Center ‘s (DTIC) semantic web technology foundation, while ensuring transaction privacy and deterring transaction-pattern based side channel attacks. With a consensus mechanism designed for mixed trust environments, the LEDGENDD architecture aligns with RDT&E community governance structure.
NIRA is developing state of the art technologies to help our customers to address their information management and sharing challenges.
Supply Chain Information Discovery based on Electronic Product Code Information Services (EPCIS)
To realize the potential of blockchains as a scalable information sharing platform, we must address the challenge of its adoption in the supply chain. Often, companies involved in handling the same products have no direct business relationships or even knowledge of one other. An information discovery infrastructure is needed to allow transaction data to be shared beyond immediate trading partners or quickly trace product origin in the event of an outbreak of a foodborne illness. The decentralized nature of the food supply chain makes blockchain an ideal technology for such an infrastructure, consistent with GS1’s “worldwide federation” vision – respecting business privacy, local preferences, and national sovereignties. Nira is exploring a block-chain based infrastructure that enables food supply chain partners and regulators to discover and access product information from authoritative sources. This infrastructure will consist of directory and credentialing services based on well-established Electronic Product Code Information Services (EPCIS) standards and will be implemented on scalable and interoperable blockchain platforms.
Our partner Sejong University Data Frameworks and Platforms Laboratory is a leader in EPCIS and Internet of Things (IoT) development. EPC Information Services (EPCIS) is a de-facto standard for information systems for object traceability. Expert and intelligent systems complying with the standard reap benefits from its global interoperability, and thus every application can easily retrieve track and trace information of everyday-objects in an identical manner.
