    Per Hurtig new docent in computer science

    Per Hurtig is the most recent docent at the Department of Computer Science. His research is about making communication on the internet faster and more efficient.

    - The number of connected units has increased tremendously in recent years, which in turn has sharpened the quality requirements considerably”, says Per Hurtig. “Both applications and users now depend on higher quality in terms of faster connection and less delays. My research is very much about how users of connected devices, such as mobile phones, can have a better experience.

    Three focus areas
    Since his thesis defence in 2012, Per’s work has been focused on three areas that reflect mobile usage and its development in society.

    Towards more usable firewalls

    Setting up firewalls correctly is a challenging task which becomes more difficult the bigger a network grows. Artem Voronkov, who recently completed a Degree of Doctor in Computer Science, has focused his work on how to help system administrators to better manage firewalls.

    Most companies have access to the Internet and their corporate networks connected to it. Many threats to computer systems, e.g. worms, trojans, and denial-of-service attacks, can be encountered online and may entail, for example, confidential data theft, service disruption and financial losses. Every organisation, regardless of its size, type of activity or infrastructure, requires network security solutions in place in order to protect it from the ever-increasing number of cyber threats.

    New methods to improve the migration of cloud services

    Users make heavy demands on cloud-based services such as Dropbox, Spotify, and Netflix. With the existing technologies, however, users experience notable service disruption, especially when they move. Kyoomars Alizadeh Noghani, who recently completed his Ph.D. in Computer Science, has investigated how leading IT companies can improve the migration of their cloud services, for example, by decreasing the duration of service disruption.

    Cloud-based services have turned increasingly popular and important over the last few years. Cloud providers offer a variety of services to the customers, including streaming, computing, and storage. People use cloud-based services such as Google Drive and Dropbox to manage and store data, Netflix to watch movies, and Spotify to listen to their favorite music. It is essential for users that these services perform well.

    New Honorary Doctor wants to protect data privacy

    During her years as a researcher and data protection commissioner, the German computer scientist Marit Hansen has been a pioneer for the concept of privacy enhancing technologies (PET). Her contribution to education and research within the field at Karlstad University has awarded her an honorary doctorate at the Faculty of Health, Science and Technology.

    Marit Hansen is a pioneer who, for the past 25 years, has been working outside of academia within the fields of data protection, personal integrity and security, using both technology and legislation. She has been working as a data protection commissioner in the state of Schleswig-Holstein in Germany since 2015, and is also involved in several other projects within the field. In 2018, she was appointed member of the National Commission on Data Ethics in Germany. Marit Hansen has in public debates and in discussions with politicians fought for data privacy as a fundamental civil right.

    Great success through excellence initiative

    In June 2019, the excellence initiative in which the Service Research Centre (CTF) and Computer Science took part since 2014, came to an end. The initiative has allowed the research groups to grow and develop in order to continue producing world-class research. This is evident in the final reports from the groups.

    Human aspects are key factors when designing new privacy-enhancing technologies

    As Internet use has increased in society, risks related to privacy online have also become more important. Researchers have developed new technologies to protect the privacy of users, but many people are unaware or choose not to use them. In a doctoral dissertation, Ala Sarah Alaqra has investigated why using privacy protection technologies is complex even though they are available.

    “Data is the new currency in this time and age and most people say that online privacy is important to them, but their behavior sometimes indicate the contrary,” says Ala Sarah Alaqra. As a researcher in the field of privacy protection, I want to find out why this is so, explore different factors, incentives, and trade-offs that affect the eco-system of data privacy, so that we can eventually be able to aid users in accepting and adopting new technologies that can protect their personal privacy online.
