Sulev Reisberg töötab Tartu Ülikooli arvutiteaduse instituudis selle nimel, et selgitada välja, milline on Eesti rahva tervis ja kuidas seda tõhusamalt ravida. Arvutid ja programmeerimine huvitasid mind juba lapsest saati. Lõin arvutimänge ja veebilehti ning seetõttu tundus loomulik samm minna ülikooli IT-d õppima. Pärast Tallinna Tehnikaülikoolis omandatud magistrikraadi olin aga kindel, et teadus pole minu […]

Kristo Raun kaitses 2024. aastal Tartu Ülikoolis doktorikraadi informaatika erialal. Praegu tegutseb ta arvutiteaduse instituudis õppejõuna ning juhib taskuhäälingusaadet „Laomees ja torumees“. Teda usutles andmeteaduse õppetooli juhataja professor Jaak Vilo. Sa said hiljuti valmis oma doktoritöö andmetehnikast ja alustasid nüüd andmeteaduse lektorina. Kirjelda palun paari lausega oma doktoritööd. Uurisin oma doktoritöös seda, kuidas teha äriprotsesside […]

E-õppe algusajaks Tartu Ülikoolis võib pidada aastat 1998, kui saadi Avatud Eesti Fondi  rahastus projektile “Avatud Ülikool kaasaegseks kaugkoolituskeskuseks”. 2023. aasta maikuus möödus sellest ajast täpselt 25 aastat. Arvutiteaduse instituudi pikaajaline vanemmetoodik Tiina Lasn, kes seda projekti juhtis, jagab järgnevalt oma mõtteid ja meenutusi. Kuidas siis täpsemalt meil e-õppega alustati?  Avatud Eesti Fondi projekti “Avatud […]

You can find out more about Kristiina Rahkema’s PhD thesis in English here.  Nutitelefonidest on saanud meie elu lahutamatu osa. Iga asja jaoks on olemas äpp: sõnumite saatmiseks, internetipanga külastuseks, auto lukust avamiseks. Kahjuks on paljud neist rakendustest ebaturvalised. Turvavigu on avastatud sellistes rakendustes nagu Facebook, TikTok ja WhatsApp. Nende turvavigade raskusaste võib ulatuda andmelekkest […]

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 […]

Jaak Vilo, Kallol Roy Algorithmics (MTAT.03.238) is an obligatory course in the Computer Science MSc curriculum. As such it is intended to remind everyone of the foundations of algorithms and data structures but also to go beyond and teach some more advanced concepts (like succinct data structures, for example).  The course aims at linking different […]

On the 13th of December Lidia Feklistova defended her PhD thesis on „Learners of an introductory programming MOOC: background variables, engagement patterns and performance” We constantly improve our knowledge and skills to be successful. Participation in massive open online courses (MOOCs) supports ongoing professional development and lifelong learning. Keeping in mind the huge number of participants in […]

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 […]

Estonia does not have many natural minerals or a significant population like many wealthy countries, but it has the most unicorns per capita globally. As most unicorns use technology to offer solutions for solving problems, we need more IT practitioners who can use computation power to solve various algorithmic issues.  “Thinking computationally is not anymore […]

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 […]

On Friday, August 28 Janno Siim defended his PhD thesis „Non-Interactive Shuffle Arguments„ A fundamental requirement for all democratic governments is a secure voting system. In recent years some countries, like Estonia and Switzerland, have adopted internet voting (i-voting), and many more have experimented (e.g., Norway and Australia) or have plans to adopt it in […]

On the 13th of August Karim Baghery defended his PhD thesis „Reducing trust and improving security in zk-SNARKs and commitments„ in which he studied the zk-SNARKs from two different perspectives, namely reducing trust in their setup phase and improving their security in different applications. On the need for proof systems People frequently are asked to […]
