Traceability not only meets the social needs of product information transparency and reinforces the trust of consumers, but also meets the needs of enterprises for brand protection and enhances the competition in markets. Since a traceability system collects every necessary information at every stage in a supply chain, it is also an efficient tool for monitoring and optimizing the production procedure. Adopting information technology to digitalize the business process is an inevitable trend to improve the efficiency in information management and especially quickly detect fraud problems. However, with the digitized process via a computer software system, the challenge remains as to whether digitized data is real. The reality shows that changing digital data is easier than paper-based data. Thus, it is necessary to have a digitalized process and a secure mechanism for ensuring transparency, correctness, and consistency of data leading to more efficiency in incidents detection and trace problems tracing. An emerging technology, Blockchain, has attracted more attention after its great success in finance due to various dominant features in preventing data changes even from the internal system. Technically, Blockchain is a ledger that records the entire transaction history publicly on a network of peer-to-peer computers of the time. One common ledger will be shared among all collaborative organizations in an ecosystem to ensure data immutability and undeniable responsibility, thereby enhancing data transparency. Therefore, applying Blockchain technology in agriculture will improve the current traceability process, aiming to increase the responsibility of the objects in the process and transparency of information for consumers. In this paper, we propose a framework that utilizes Blockchain to robustize traceability systems. Additionally, our proposed framework is compliant with the GS1 standard to achieve high reliability and compatibility on a global scale.

Objective Being

Photogrammetry has been in use for over one hundred and fifty years. This research considers how digital image capture using a medium range Nikon Digital SLR camera, can be transformed into 3D virtual spatial images, and together with additive manufacturing (AM) technology, geometric representations of the original artefact can be fabricated. The research has focused on the use of photogrammetry as opposed to laser scanning (LS), investigating the shift from LS use to a Digital Single Lens Reflex (DSLR) camera exclusively. The basic photogrammetry equipment required is discussed, with the main objective being simplicity of execution for eventual realisation of physical products. As the processing power of computers has increased and become widely available, at affordable prices, software programs have improved, so it is now possible to digitally combine multi-view photographs, taken from 360°, into 3D virtual representational images. This has now led to the possibility of 3D images being created without LS intervention. Two methods of digital data capture are employed and discussed, in acquiring up to 130 digital data images, taken from different angles using the DSLR camera together with the specific operating conditions in which to photograph the objects. Three case studies are documented, the first, a modern clay sculpture, whilst the other two are 3000 year old Egyptian clay artefacts and the objects were recreated using AM technology. It has been shown that with the use of a standard DSLR camera and computer software, 2D images can be converted into 3D virtual video replicas as well as solid, geometric representation of the originals.

Cross Border

Cross-border e-commerce, involving international product transactions via online and mobile platforms, is growing at a dramatic rate around the globe. One of the main concerns of brand firms is preventing counterfeit products from being sold under their names on e-commerce platforms. Counterfeit goods not only create economic losses to both the supply and demand sides, but also undermine efforts to improve sustainability. Proliferating counterfeits harm the brands of supply firms and trust in selling e-commerce platforms. In addition, they discourage participants in the supply chain from investing in social and environmental sustainability. If end-customers have access to detailed and comprehensive product information with a traceability system that can help overcome information uncertainty and asymmetry, losses can be prevented. The result of the pilot test has shown that securely shared in-depth product information among supply chain stakeholders from the supply side to end-customers can help prevent counterfeit goods from proliferating further by enabling consumers to determine the authenticity of products and report forgeries before paying.

Blockchains are attracting the attention of stakeholders in many industrial domains, including the logistics and supply chain industries. Blockchain technology can effectively contribute in recording every single asset throughout its flow on the supply chain, contribute in tracking orders, receipts, and payments, while track digital assets such as warranties and licenses in a unified and transparent way. The paper provides, through its methodology, a detailed analysis of the blockchain fit in the supply chain industry. It defines the specific elements of blockchain that affect supply chain such as scalability, performance, consensus mechanism, privacy considerations, location proof and cost, and details on the impact that blockchains will have in disrupting the supply chain industry. Discussing the tradeoff between consensus cost, throughput and validation time it proceeds with a suggested high-level architectural approach, and concludes as a result with a discussion on changes needed and challenges faced for an in-vivo deployment of blockchains in the supply chain industry. While the technological features of modern blockchains can effectively facilitate supply chain uses cases, the various challenges that still remain, bring in front of us a wide set of needed changes and further research efforts for achieving a global, production level blockchain for the supply chain industry.
