    The services sector strategic development unites a multitude of economic and managerial aspects and is one of the most important problems of economic management. Many researches devoted to this industry study are available. Most of them are performed in the traditional aspect of the voluminous calendar approach to strategic management, characteristic of the national scientific school. Such an approach seems archaic, forming false strategic benchmarks. The services sector is of special scientific interest in this context due to the fact that the social production structure to the services development model attraction in many countries suggests transition to postindustrial economy type where the services sector is a system-supporting sector of the economy. Actively influencing the economy, the services sector in the developed countries dominates in the GDP formation, primary capital accumulation, labor, households final consumption and, finally, citizens comfort of living. However, a clear understanding of the services sector as a hyper-sector permeating all spheres of human activity has not yet been fully developed, although interest in this issue continues to grow among many authors. Target of strategic management of the industry development setting requires substantive content and the services sector target value assessment

    The land registry system is one of the very important department in any governance system that stores the records of land ownership. There are various issues and loopholes in the existing system that give rise to corruption and disputes. This requires a significant chunk of valuable government resources from judiciary and law enforcement agencies in settling these issues. Blockchain technology has the potential to counter these loopholes and sort out the issues related with land registry system like tempering of records, trading of the same piece of land to more than one buyer. In this paper, a secure and reliable framework for land registry system using Blockchain has been proposed. The proposed framework uses the concept of smart contract at various stages of the land registry and gives an algorithm for pre-agreement. First, we describe the conventional land registry system and reviews the issues in it. Then, we outline the potential benefits of employing Blockchain technology in the land registry system and presented a framework. Finally, a number of case studies are presented

    The appearance of so-called block chains or Blockchain with the promise of transforming trust and the way value is exchanged, joins the expansion of the technological capabilities of organizations to achieve higher levels of productivity and innovation. This is how Blockchain-based techniques are being applied to many fields, focusing in this article on the public sector, as a possible solution to the demands for transparency, participation and citizen cooperation that society demands; due to the possibility of disintermediation based on automated transactions and on the responsibility and security in the management of official blockchain records. This could obstruct corruption and make government services more transparent and efficient. Although, it investigates about applications in the public sector under the Blockchain system, such as transactions, agreements, property registries and innovations, developments and other assets; Special emphasis is placed on the possibility of implementing Smart Contracts (mechanisms that aim to eliminate intermediaries to simplify processes) in public procurement procedures, given that it is in this type of activity where high levels of corruption are generated. It is concluded then that Europe has the largest number of blockchain initiatives worldwide, while Latin America, except for the case of Peru, lacks this type of applications, being this continent exactly where there are the countries with the highest levels of corruption. It concludes with a recommendation to use blockchain along with smart contracts through platforms such as Ethereum or Lisk, mainly given its flexibility and current development on topics with similar functionalities

    The current mechanism to secure Border Gateway Protocol relies on the resource public key infrastructure (RPKI) for route origin authorization. The RPKI implements a hierarchical model that intrinsically makes lower layers in the hierarchy susceptible to errors and abuses from entities placed in higher layers. In this article, we present InBlock, a distributed autonomous organization that provides decentralized management of IP addresses based on blockchain, embedding an alternative trust model to the hierarchical one currently implemented by the RPKI. By leveraging on blockchain technology, InBlock requires consensus among the involved parties to change existent prefix allocation information. InBlock also fulfills the same objectives as the current IP address allocation system, i.e., uniqueness, fairness, conservation, aggregation, registration, and minimized overhead. InBlock is implemented as a set of blockchain smart contracts in Ethereum, performing all the functions needed for the management of a global pool of addresses without human intervention. Any entity may request an allocation of addresses to the InBlock registry by solely performing a (crypto) currency transfer to the InBlock. We describe our InBlock implementation and we perform several experiments to show that it enables fast address registering and incurs in very low management costs.Publicad

    Constructing privacy aware blockchain solutions: design guidelines and threat analysis techniques

    Get PDF
    Blockchain is an incipient technology that offers many strengths compared to traditional systems, such as decentralization, transparency and traceability. However, if the technology is to be used for processing personal data, complementary mechanisms must be identified that provide support for building systems that meet security and data protection requirements. In this work we study the integration of off-chain capabilities in blockchain-based solutions, moving data or computational operations outside the core blockchain network. Additionally, we develop a thorough analysis of the European and Uruguayan data protection regulation and discuss the weaknesses and strengths, regarding the security and privacy requirements established by that regulation, of solutions built using blockchain technology. Based on this analysis, we present a system architecture for the design of privacy aware solutions that are built using blockchain technology. We also put forward a systematic approach for performing a security and privacy threat analysis of such kind of solutions. Finally, we illustrate the use of the proposed methodological tools, presenting and discussing both the design and the security and privacy assessment of a system that provides services to handle, store and validate digital academic certificates.Blockchain es una tecnología incipiente que ofrece muchas fortalezas en comparación con los sistemas tradicionales, como la descentralización, la transparencia y la trazabilidad. Sin embargo, si se va a utilizar esta tecnología para el procesamiento de datos personales, se deben identificar mecanismos complementarios que brinden soporte a los sistemas de construcción que cumplan con los requisitos de seguridad y protección de datos. En este trabajo estudiamos la integración de capacidades de soluciones offchain en soluciones basadas en blockchain, moviendo datos u operaciones computacionales fuera de blockchain. Adicionalmente, desarrollamos un análisis exhaustivo del reglamento europeo y uruguayo de protección de datos personales y discutimos las debilidades y fortalezas, en cuanto a los requisitos de seguridad y privacidad que establece dicho reglamento, de las soluciones construidas con tecnología blockchain. En base a este análisis, presentamos un marco metodológico para el diseño de soluciones basadas en tecnología blockchain, pensando en la privacidad. También presentamos un enfoque sistemático para realizar un análisis de amenazas a la seguridad y la privacidad de este tipo de soluciones. Finalmente, ilustramos el uso de las herramientas metodológicas propuestas, presentando y discutiendo tanto el diseño como la evaluación de seguridad y privacidad de un sistema que brinda servicios para manejar, almacenar y validar certificados académicos digitales

    A business process model for blockchain-based South African real estate transactions

    Get PDF
    The real estate transaction process has been described as inefficient and technologically outdated due to numerous stakeholders and predominantly paper-based operations. Despite the apparent bottlenecks in the current process, the implementation of new technology into the real estate sector has lagged. Several attempts have been made to modernise and digitise the business process but committed integration of assisting technology has lacked attention. This study examined the applicability and potential integration of blockchain technology into the business process of South African real estate transactions. Blockchain’s novelty means that research in this space, especially within South Africa, is limited. Of the research that has been conducted, no models of the business processes for South African or blockchain-based real estate transactions have been constructed. This study provides two business process models, illustrating the two different processes. The main contribution of this paper was an integrated business process model, illustrating how the various processes and stakeholder interactions for South African blockchain-based real estate transactions are conducted on one transaction platform, common to all participating stakeholders. This platform was named the South African Blockchain Land Exchange System (SABLES), which manages and facilitates these transactions in their entirety from start to finish. This model depicts an enhanced business process that provides increased security, transparency, and speed. These benefits will be realised by those who register, adopt, and transact on the platform. Through in-depth interviews, the integrated business process model was assessed. The findings produced a final and combined thematic map, representing the main themes of the analysed interview data, namely blockchain implementation strategies, business process applicability, information technology assimilation, current transaction context, and PropTech 3.0 success factors. The discussion revealed that the current transaction process lacks technological innovation, which increases pressure on the conveyancing role. It was also revealed that there is not only a need within the industry, but a desire, for newer technologies to assist the transaction process. In order to streamline and improve efficiency, business processes should leverage digital records and data, and strive for a solution beyond digitisation, achieving digitalisation. Digitalisation recognises digital documents as official and legal documents as opposed to simply being digital back-ups. This, coupled with the business process models, represent theoretical contributions

    Get PDF
    The blockchain was initially developed for use in the banking sector. However, over time, different areas of knowledge have adopted these technologies, including transportation operations. This use of blockchain in the transport sector is mainly due to the ability of this technology to enable the data generated by these activities to be reliable. In addition to aspects related to data immutability, blockchain enables greater data privacy, as well as making it possible for the data control process to be decentralized. In this sense, it was carried out a systematic literature review (RSL) to identify the general publications panorama on the topic, and to identify the capabilities enabled by the blockchain in the context of transportation operations. RSL has great potential to make it possible to deepen the literature on a given topic. The analysis of the RSL results included the realization of two stages. The first step consisted of a quantitative analysis of data from a sample of 50 articles, to identify this research field about the distribution by journal, year, and author. This first step enabled a general analysis of the field of study on the use of blockchain in transportation. The second stage consisted of a qualitative analysis of the ten most relevant articles in this field of study. In this way, it was possible to understand more about the use of blockchain in transport operations, as well as to identify seven capabilities enabled by the blockchain. These capabilities represent abilities that blockchain technology allows the transport sector today, demonstrating the importance of its use, as well as of study
