With the development of Online Social Media (OSM) platforms like Twitter and Facebook, the way individuals connect and exchange information has changed dramatically. These platforms have, however, also led to the problem of misinformation, which can quickly spread on a global scale, and once it has been disseminated, it can be hard to stop. It […]

Introduction: Privacy-preserving computation is a crucial discipline that protects the privacy of confidential data while facilitating secure analysis. In graph problems, secure multiparty computation (SMC) presents a promising approach to performing these functionalities. This article delves into the notable advancements in privacy-preserving parallel algorithms recently introduced in a Ph.D. thesis. By integrating graph algorithms with […]

Kadi Tulver, arvutiteaduse instituudi kognitiivteaduse ja masinnägemise teadur Lugu sellest, kuidas Isaac Newton õunapuu all istudes murrangulise gravitatsiooniteooria peale tuli, on kõigile tuttav. Isegi kui mõned värvikad detailid on ilukirjanduslikult liialdatud, ilmestab see episood suurepäraselt ühte inimmõistusele unikaalset omadust – kuidas uudsed ideed mõnikord meile justkui tühja koha pealt pähe hüppavad. Püüdlustes luua tehisintellekti, mis […]

We are currently in the process of significant changes in the communications paradigms. Among others, one of the changes is moving to cloud-based services instead of using local applications (Office365, Youtube, Spotify, etc.). We can argue about the motivation of this trend, but this allows us to provide the customers with the most up-to-date solutions […]

Researchers from the University of Tartu’s Institute of Computer Science are taking part in the EU Horizon project SPATIAL (Security and Privacy Accountable Technology Innovations, Algorithms and Machine Learning), which aims to develop resilient accountable metrics, privacy-preserving methods, verification tools and system solutions that will serve as critical building blocks for trustworthy AI in ICT […]
