The present book includes extended and revised versions of a set of selected papers presented at the 18th International Joint Conference on e-Business and Telecommunications, ICETE 2021, held as an online web-based event (due to the COVID-19 pandemic) in July 2021. The 17 full papers included in this book were carefully reviewed and selected from 197 submissions. They were organized in topical sections as follows: e-Business and security and cryptography.

Information and its management is central to modern society. Organizations ? private and public, national and international ? have recognized that information is a key resource and that its management is critical for success.

Existing books on information management focus on the abilities of computers to process data, the development of information systems, and the management of IT resources. They often start with the computer as a key issue. Although Information Management acknowledges the importance of computers and data communication, it starts from a deeper understanding of the concepts of information and knowledge, and on the basis of this understanding, derives methods to use computers effectively. This textbook provides graduates of any discipline with an understanding of the theory and practice that underpins information management, and introduces students to the concepts and applications of information management techniques in a variety of organizational contexts.

In giving students strong philosophical foundations, Fons Wijnhoven's book will prove to be an excellent primer in information management.

The ability to manage knowledge is relevant for millions of small and medium sized enterprises (SMEs) that operate in high-tech environments. They strongly depend on external knowledge about customers, technologies, and competitors because, as opposed to large companies, they have limited internal knowledge resources and little power to control their business environments. Present KM literature, however, mainly focuses on large companies and therefore does not explain, how SMEs, for example, can successfully apply groupware, data mining, semantic networks, and knowledge maps. This book addresses this problem by introducing the concept of knowledge integration (KI) that places emphasis on the identification, acquisition and use of external knowledge. Drawing from this theoretical basis, the book presents concepts and instruments specifically designed for SMEs, as well as examples of their implementation and use in practice.
