Risto Hinno on hea näide sellest, kuidas karjäär võib võtta põneva pöörde. Varasemalt digiteenuste tellijana töötanud Risto otsustas süvendada oma teadmisi IT-valdkonnas ning asus õppima Tartu Ülikooli arvutiteaduse instituudi magistriõppekaval „IT mitteinformaatikutele“ . Õpingute käigus avanes talle arenduse ja andmeteaduse maailm sedavõrd kaasahaaravalt, et see viis ta lõpuks ka idufirmasse tööle. Oma kogemusloos jagab ta ausalt teekonda […]

Toomas Gross on suure ja mitmekülgse akadeemilise kogemusega antropoloog, kes on töötanud aastaid õppejõu ja teadlasena. Oma töös jõudis ta arusaamani, et nüüdisaegne teadus ja õppetöö eeldavad üha enam ka tehnoloogilist ning andmeteaduslikku kirjaoskust. Soov end proovile panna ja intellektuaalsest mugavustsoonist väljuda viis ta Tartu Ülikooli arvutiteaduse instituudi magistriõppekava „IT mitteinformaatikutele“ alusel õppima. Kogemusloos kirjeldab […]

Kaspar Kala läbis Tartu Ülikooli arvutiteaduse instituudi magistriõppekava „IT mitteinformaatikutele“. Varem on ta õppinud õigusteadust nii Eestis kui ka Hollandis ning praegu töötab projektijuhi, analüütiku ja majasisese juristina. Kaspar on justkui sild kahe valdkonna, IT ja õiguse vahel. Loe Kaspari kogemuslugu informaatika õppimisest. Enne informaatikaõppesse kandideerimist määratlesin end eelkõige juristina. Lõpetanud õigusteaduse bakalaureuseõpingud Tartu Ülikoolis ja […]

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 […]

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 […]

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 […]
