Raimundas Matulevičius – författare

The papers are centered around topics like architectures and quality of information systems, artificial intelligence in information systems, data and knowledge engineering, enterprise and information systems engineering, security of information systems. *The conference was held virtully due to the COVID-19 pandemic.

This book constitutes the proceedings of the 25th European Conference on Advances in Databases and Information Systems, ADBIS 2021, held in Tartu, Estonia, in August 2021. The 18 full papers presented together with 3 keynotes were carefully reviewed and selected from 70 submissions.

This book constitutes thoroughly reviewed and selected short papers presented at the 25th East-European Conference on Advances in Databases and Information Systems, ADBIS 2021, as well as papers presented at doctoral consortium and ADBIS 2021 workshops.

This book constitutes the proceedings of the Blockchain, Robotic Process Management (RPA), and Central and Eastern Europe (CEE) Forum which were held as part of the 20th International Conference on Business Process Management, BPM 2022, which took place in Münster, Germany, during September 11-15, 2022.The Blockchain Forum is dealing with techniques for and applications of blockchains, distributed ledger technologies, and related topics."The RPA Forum brings together researchers from various communities to discuss challenges, opportunities, and new ideas related to robotic process automation and its application to business processes in private and public sectors." The CEE Forum provides a discussion platform for BPM academics from Central and Eastern Europe to disseminate their research, compare results and share experiences. The 20 papers presented in this volume were carefully reviewed and selected from a total of 40 submissions.

This book constitutes the proceedings of the 23rd International Conference on Perspectives in Business Informatics Research, BIR 2024, which took place in Prague, Czech Republic, in September 2024.

This book constitutes the refereed proceedings of the 30th Nordic Conference on Secure IT Systems, NordSec 2025, held in Tartu, Estonia, during November 12-13, 2025.The 29 full papers included in this book were carefully reviewed and selected from 89 submissions. They were organized in topical sections as follows: Cryptography; Artificial Intelligence and Software Security; Network and Communication Security; System and Hardware Security; Threat Analysis; Access Control and Policy Management; Usable Security and Societal Resilience; and Obfuscation.

The papers have been organized in topical sections on business information systems interoperability, business information system requirements and architecture, business process and decision management, business information systems development, and research in progress.

This book provides a coherent overview of the most important modelling-related security techniques available today, and demonstrates how to combine them. Further, it describes an integrated set of systematic practices that can be used to achieve increased security for software from the outset, and combines practical ways of working with practical ways of distilling, managing, and making security knowledge operational.The book addresses three main topics: (1) security requirements engineering, including security risk management, major activities, asset identification, security risk analysis and defining security requirements; (2) secure software system modelling, including modelling of context and protected assets, security risks, and decisions regarding security risk treatment using various modelling languages; and (3) secure system development, including effective approaches, pattern-driven development, and model-driven security.The primary target audience of this book is graduate students studying cyber security, software engineering and system security engineering. The book will also benefit practitioners interested in learning about the need to consider the decisions behind secure software systems. Overall it offers the ideal basis for educating future generations of security experts.

This book constitutes the proceedings of the 22nd Nordic Conference on Secure IT Systems, held in Tartu, Estonia, in November 2017. The 18 full papers presented were carefully reviewed and selected from 42 submissions. The papers address a broad range of topics in IT security and privacy.
