48 – Human aspects of data privacy

Securing data privacy on the internet is a wicked problem. It is wicked in that technological, legal, and human aspects of privacy are entangled. In her licentiate thesis Ala Sarah Alaqra has focused on the human aspects of data privacy. By letting users test a privacy enhancing scheme – redactable signatures – designed by Ala and her colleagues, her research investigates user perceptions and opinions of data privacy in eHealth. In our conversation Ala let us know more of redactable signatures, and how it can help increase data privacy in eHealth and possibly in other sectors as well.

44 – Mathematical analysis of multiscale systems

If you pour a liter of water in an already half filled two liter bottle, you’ll usually fill it up completely. But what if the bottle wasn’t filled with liquids, but with sand and air? The mathematics you need to calculate such processes is complex and requires a so-called multiscale approach: calculating the interactions between objects with vastly different sizes. In his research, Ph.D. candidate Omar Richardson is developing a mathematical framework to analyze these and other multiscale systems. In our conversation, Omar explains how and why we do mathematical research, and describes some practical implications of his work.

43 Privacy friendly mobile apps

Mobile phone applications can be great for a range of different everyday purposes. However, most users are unaware of what the apps are doing while they are unattended. In his research, Ph.D. candidate Nurul Momen has investigated how apps behave, and how they use the personal data users authorise them to access. In our conversation, Nurul describes the dangers of personal data craving apps, and he explains how his research can help increasing transparency and protect user privacy.

41 – Improving transparency in personal data processing

The European Union’s General Data Protection Regulation has been implemented to protect citizens’ data privacy by, for example, increasing control over their personal data. However, computerized systems and web services are not always effectively designed to give users the control they are legally entitled to in a usable way. In her thesis, Farzaneh Karegar, Ph. D. student in computer science, develops new solutions that enhance transparency and make it easier for users to give better-informed consent to service providers handling personal data. In our conversation Farzaneh lets us know more about the solutions, and why it is important to continue to work to improve the gap between legally-compliant and usable services.
