Blockchain-based Information Sharing and Protection
To support secure and effective information distribution within the Defense Research, Development, Testing, and Evaluation (RDT&E) community, Nira is working with Defense Technical Information Center (DTIC) on a blockchain-based solution known as the LEDGEr-based Network for Document Distribution (LEDGENDD™). The LEDGENDD™ solution draws upon lessons learned from previous research on enforcing data access right policies in a distributed manner, including Digital Rights Management (DRM) architectures introduced by the entertainment industry. Instead adopting a “security through obscuration” approach that depends on proprietary file formats, LEDGENDD™ implements distributed access control using open standard-based and patent-pending container documents, which in turn use public key infrastructure (PKI) to protect contents being distributed.
NIRA is developing art 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.
