    Fingerprint Quality: a Lifetime Story
    (BIOSIG 2018 - Proceedings of the 17th International Conference of the Biometrics Special Interest Group, 2018) Galbally, Javier; Haraksim, Rudolf; Beslay, Laurent
    Currently, it is a largely accepted fact that biometric sample quality is the most determinant factor to achieve high recognition accuracy in biometric systems. However, even in extensively researched characteristics such as fingerprints, there is still a lack of evidence on how quality evolves throughout the life of an individual. For instance, how does the quality of children fingerprints compare to that of adults or elders? Do these changes imply any age limits for the use of fingerprints with current technology? The present paper addresses this key problem based on a database of over 400K fingerprints coming from more than 250K different fingers. The database was acquired under real operational conditions and contains fingerprints from subjects aged between 0 and 98 years. Such a unique set of data has allowed us to analyse for the first time how fingerprint quality changes through life.

    Impact of Gender and Age on performing Search Tasks Online
    (Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Singer, Georg; Norbisrath, Ulrich; Lewandowski, Dirk
    More and more people use the Internet to carry out tasks of their daily work routine. To find the right information online Web search engines are the tools of their choice. Apart from finding facts, people use search engines to also execute rather complex and time consuming search tasks. So far search engines have been following the one-for-all approach to serve its users and little is known about the impact of gender and age on people s Web search performance. In this article we present a study that examines (1) how female and male Web users carry out simple and complex search tasks, and (2) how the age of the users impacts their search performance. The laboratory study was done with 56 ordinary people carrying out 12 search tasks each. Our findings confirm that age impacts the search performance significantly while gender influences were smaller than expected.
