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 […]

On the 9th of December Jakob Mass defended his PhD thesis on „Process management for Internet of mobile things“. The Internet of Things (IoT) promotes solutions such as a smart city, where everyday objects connect with info systems and each other. One example is a road condition monitoring system, where connected vehicles, such as buses, […]

On the 30th of September, Mubashar Iqbal defended his PhD. thesis on “Reference Framework for Managing Security Risks Using Blockchain” which addresses the problem of traditional applications’ security risk management (SRM) using blockchain as a countermeasure solution and the SRM of blockchain-based applications. In the digital realm, software security has the utmost importance in making […]

The cornerstone of democracy is the right for voters to participate in free and fair elections. However, securing elections is a non-trivial task due to the conflicting security requirements.  On the one hand, to provide the freedom to vote, it should not be possible to coerce voters into voting for a specific candidate. Therefore, the […]

More than 2000 participants were involved in cyber defence exercise Locked Shields 2022 that took place from April 19 to 22. This year, one of the venues of the event was the Delta Centre in Tartu. Employees of the HPC Center of the University of Tartu and the Institute of Computer Science participated in the […]

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 […]

The article was translated and published in English by the University of Tartu. It was initially published in Estonian in Eesti Ekspress by Greete Lehepuu. The cover of the September issue of Communications of ACM, the most prestigious journal in computer science, featured an article led by University of Tartu researchers. The article proposes steps to tackle one of […]

The original article (in Estonian) by Airika Harrik was published in Novaator. Estonia has used the ID card system as a means to identify its citizens for almost 20 years. During those years, several security issues have emerged. A new PhD dissertation from the University of Tartu has shed light on those issues and pointed […]

Oma ligi 80-aastase ajaloo juures on elektronarvutid fundamentaalselt muutnud info kogumist, töötlust ja kommunikatsiooni. Kiirete numbriliste arvutuste võimaldajast (computer oli ametinimetus käsitsi arvutajatele, peamiselt tegelesid sellega meestest palju hoolikamad naised) sai kuuekümnendatel ettevõtete andmete, palgatšekkide ja reserveeringute haldaja. Kui 1980ndatel jõudsid personaalarvutid ja tabelarvutus massidesse, kadusid masinakirjutajad. Edasi avas ülemaailmne võrk Internet ligipääsu kaugel olevale […]

On December 21, Madis Vasser defended his PhD thesis „Testing a Computational Theory of Brain Functioning with Virtual Reality“. In his thesis, he investigated the concept of active inference (AI) using virtual reality (VR) devices. During the work they developed VR software, conducted experiments on human study participants and compiled a set of guidelines for […]

Ülikooli rahastus pole mõeldud töökohtade hoidmiseks, vaid ikka eelduste loomiseks ja riigi arendamiseks. Oma koht on siin ka välistudengitel ja rahvusvahelistumisel. Selgitan seda informaatika kõrghariduse näitel. On suurepärane, et meil toimub arutelu kõrghariduse ja teaduse rolli üle Eesti riigi, kultuuri ja rahvuse säilimisel. Just selles kontekstis vastan Jaak Valge küsimusele «Kas välisüliõpilasele stipendiumi maksmine tõstab […]
