Acta Informatica Pragensia 2020, 9(1), 30-47 | DOI: 10.18267/j.aip.1304643  

Scientific and technological developments in informatics enable intensive transformation of data into valuable information. Enriched with context, information may be turned into knowledge, allowing organizations to optimize their processes and profile themselves as learning knowledge organizations. Several classifications of knowledge and knowledge management are available in scientific literature and research publications. In this paper the implementation and application of information and communication technology in knowledge management is being assessed from the perspective of synchrony and mutual interaction among collaborating parties.  Following...

Katerina Prihodova, Miloslav Hub

Acta Informatica Pragensia 2020, 9(1), 48-57 | DOI: 10.18267/j.aip.1314045  

Today, data security is an increasingly hot topic, and thus also the security and reliability of end-user identity verification, i.e. authentication. In recent years, banks began to substitute password authentication by more secure ways of authentication because passwords were not considered to be secure enough. Current legislation even forces banks to implement multi-factor authentication of their clients. Banks, therefore, consider using biometric authentication as one of the possible ways. To verify a user's identity, biometric authentication uses unique biometric characteristics of the user. Examples of such methods are facial recognition, iris...

This note deals with the impact of the COVID-19 pandemic crisis on the ways how academic conferences are organized and run. Specifically, I reflect on my personal experience gathered during the attendance of the 21st International Conference on Agile Software Development, which was organized as a solely virtual event for the first time. First and foremost, I summarize the technical and other challenges encountered as a conference presenter and participant. Then, I shortly discuss a possible impact of the COVID-19 pandemic on the future publication standards in the sciences of computing.
