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 […]

Data privacy has become trending, and nowadays, people are talking more and more about it. With process mining, privacy becomes more relevant. Because process mining makes it easier to expose the actual business reality. With automatic process discovery, we can reverse engineer the activities that have been performed within the organization and the hand-offs between […]

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 […]

Nowadays, a vast majority of business processes involve many tedious and repetitive tasks, for example transferring data across multiple systems or transforming data from one format to another. These tasks are time-consuming, error-prone, and by themselves do not bring much value to the underlying processes. Their automation can bring many benefits such as error-rate reduction, […]

Modern organizations must constantly adjust their business processes in order to adapt to internal and external changes, such as new competitors, new regulations, customer expectations, or strategic objectives. For example, due to a pandemic, a retailer might experience a 50% increase in their number of online orders; however, during the same time, their volume 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 […]

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 […]

We are happy to share the great news that the paper “Designing Corporate Hackathons With a Purpose: The Future of Software Development” co-authored by our Associate Professor Alexander Nolte with colleagues from Carnegie Mellon University, Github and Microsoft was named as the Runner-up for the 2019 Best Paper Award from IEEE Software by the IEEE […]

On September 25, Orlenys López Pintado defended his PhD thesis „Collaborative Business Process Execution on the Blockchain: The Caterpillar System“.
