Abstract
Trust lies at the foundation of all commercial and administrative transactions, which for centuries have relied upon the handwritten signature for authentication. As transactions are digitalized, the signatures that provide trust in them must also become electronic. The lack of trusted and legally recognized means of authenticating electronic transactions has forced a continued reliance on in-person handwritten signatures, undermining digitalization efforts by necessitating recourse to in-person interaction to complete a transaction. In-person handwritten signatures in the analogue world are not a particularly secure means of authentication. When transactions are digitalized, new security issues arise, as the ease with which digital data can be duplicated or altered introduces additional vulnerabilities that never existed with paper. To address these concerns, electronic signature frameworks provide a means of authenticating the various electronic transactions in a way that facilitates the emergence of a trusted digital economy. This policy note presents electronic signatures in terms of their four main functions: (1) identifying the signer, (2) attributing the signature to the signer, (3) recording the signer’s intent to sign, and (4) assuring the integrity of the signed data and protecting against tampering. Not all transactions require a high degree of assurance of all four of these functions. Indeed, for lower-risk transactions, attempting to assure a high level of trust in all four functions may be counterproductive, for example, if doing so leads to excessive cost or frictions for users that dissuade them from transacting in the first place. Therefore, policy makers should balance priorities between security and usability to ensure widespread adoption of electronic signature solutions.

Publication Implementing Electronic Business Registry Services(2007-06-29)The objective of this paper is to share the experiences and good practices of early business registry reformers who implemented web-enabled and automated electronic business registries (e-BRs). These lessons are hoped to be of help to EU New Member countries as they embark on delivering EU-conformant e-BRs. At the same time, policymakers in other developing countries may also find these lessons of use. This paper cites examples of good practices rather than best practices. As elsewhere in the development agenda, solutions that have worked well in some countries may not work in other local circumstances. In the case of e-BRs, success depends on a broader set of reforms; as will be discussed in a subsequent chapter, e-BRs require a supportive legal and regulatory infrastructure, such as electronic signature laws and document authentication. A needs assessment and analysis of the options in the local country context need to be conducted in order to find the most relevant best practice options for a specific country. Nevertheless, a number of practical good practices can be identified and are presented in this paper for consideration.Publication Authentication and Digital Signatures in E-Law and Security : A Guide for Legislators and Managers(World Bank, Washington, DC, 2004-12)The concept of authentication has been around for a long time in many forms. For example due diligence in commerce has traditionally been formalized to determine whether the data presented in commercial propositions are accurate and comprehensive. With the emergence of e-commerce the concept of authentication has encompassed new realities that are a feature of the relatively narrow avenues for information and potentially high risks inherent in an online environment. This paper seeks to provide an understanding about the different ways of assuring authentication. These authentication rules and tools including for example public key infrastructure (PKI) are sometimes meant to set a legal and technological framework for trustworthy electronic transactions, promoting e-procurement, e-commerce, e-business, and e-government. The two considerations of business risk and legal validity are both intrinsic to the concept of authentication. This report explores the issues and solutions affecting the concept of authentication in terms of legislation, management and technology. This report finds that for online authentication things is not always what they may seem and that legislation and technology alone cannot build a trust environment and, if misunderstood, may produce a high risk illusion. It is crucial that the limitations and fallibility of the technology be explicit in its commercial applications and that business risks be managed accordingly.Publication Can Electronic Tax Invoicing Improve Tax Compliance?(World Bank, Washington, DC, 2016-03)This paper reviews the Republic of Korea's experience with electronic tax invoices for its value-added tax regime from the perspectives of tax policy makers and administrators. The paper evaluates Korea's implementation of electronic tax invoicing and analyzes its effect on tax compliance through enhanced transparency of business transactions and taxpayer services. First implemented in 2011, mandatory electronic tax invoicing has been credited with lowering tax compliance costs and raising the transparency of business transactions. Effective policy design and implementation have contributed to the country's success with electronic tax invoicing. Measured in transaction value, the electronic tax invoice adoption rate reached 99.8 percent in the first year and rose to 99.9 percent by 2013, compared with 15 percent before electronic tax invoicing became mandatory. According to a survey of taxpayers and tax practitioners in Korea that was conducted as part of this research study, 69.4 percent of the respondents agreed or strongly agreed that mandatory electronic tax invoicing has contributed to curbing value-added tax evasion by raising transaction transparency, and 72.9 percent agreed or strongly agreed that it has improved taxpayer service by facilitating the convenience of tax filing or automating the issuance of invoices. The review of Korea's experiences gives credence to the contention that well-planned and well-executed compulsory electronic tax invoices can materially enhance tax compliance through significant institutional and perceptual changes in tax administration.Publication Afghanistan - Electronic Government Procurement Readiness Assessment and Roadmap(Washington, DC, 2007-06)The overriding objective of a national public procurement system is to deliver efficiency and value for money in the use of public funds, while adhering to fundamental principles of non- discrimination, equal treatment, and transparency. Procurement is therefore at the core of the Public Finance Management (PFM) system and contributes greatly to several of its objectives, including efficiency, transparency, and accountability. In respect of public procurement, the 2005 review of Afghanistan's PFM system identified a weak legal framework, lack of ownership, lack of capacity and the lack of a monitoring mechanism as the key issues in the area of procurement. Since then, following the recommendations of the PFM review report, the country has made substantial progress in improving its public procurement environment. The purpose of this report is to provide a roadmap which sets out the incremental steps which may be taken to introduce Electronic Government Procurement (E-GP) tools according to the speed and development of the reform agenda. The report will be disseminated to the stakeholders through a workshop, planned for July 2007. The workshop will discuss the challenges in implementation of an e-GP strategy both in terms of its components as well as the transition path to implementation.Publication Digital Identity Toolkit : A Guide for Stakeholders in Africa(Washington, DC, 2014-06)Digital identity, or electronic identity (eID), offers developing nations a unique opportunity to accelerate the pace of their national progress. It changes the way services are delivered, helps grow a country's digital economy, and supports effective safety nets for disadvantaged and impoverished populations. Though digital identity is an opportunity, it raises important considerations with respect to privacy, cost, capacity, and long-term viability. This report provides a strategic view of the role of identification in a country's national development, as well as a tactical view of the building blocks and policy choices needed for setting up eID in a developing country. The report presents a conceptual overview of digital identity management practices, providing a set of guidelines at a national level that policymakers can find helpful as they begin to think about modernizing the identity infrastructure of their country into eID. The report also provides an operating knowledge of the terminology and concepts used in identity management and an exposition of the functional blocks that must be in place. Policy considerations are referenced at the end of the report that governments can use as they contemplate a digital identity program. Given its abridged nature, the report is intended to be insightful and detailed, though not exhaustive. Several important topics related to eID are noted though deserve further discussion, including: economic and financial analysis, the development and setup of a national civil register, and cross-border aspects of eID. The building blocks, as discussed, can help ensure that a secure, robust and reliable digital identity platform can serve the development needs of a country for the foreseeable future.

Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication The Container Port Performance Index 2023(Washington, DC: World Bank, 2024-07-18)The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.Publication China Economic Update, June 2024(Washington, DC: World Bank, 2024-06-14)Economic activity picked up in China in early 2024, buoyed by stronger exports. Meanwhile, growth in domestic demand moderated. Manufacturing and infrastructure investment and consumer spending on services remained robust, while the property market correction continued. In the long term, China’s rapidly aging population will have wide-ranging economic impacts, but with the right policies the demographic transition is manageable. The economic challenges from an aging population can be overcome with policies that increase labor force participation and extend productive working lives. Affordable childcare, better work-life balance, elimination of gender bias in hiring, a higher retirement age, skills upgrading, and lifelong learning are measures that could expand China’s workforce and make it more productive.Publication Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.
