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 […]

We are living in a world in which data is not just getting bigger; it is also getting more and more interconnected. Large graph analytics is a useful tool for gaining insights from large volumes of interconnected data and has applications in various fields such as social media, biology, and telecommunications. An example of the […]

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, […]

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 […]

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 […]

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 […]
