    • Creating 3D-artefacts for spoofing fingerprint readers 

      Ry, Emil Volckmar (Master thesis, 2018)
      In this thesis we assess the different challenges of making 3d printed artefacts with 1.75mm PLA filaments. In this thesis we have been able to verify knowledge already in the body of knowledge such as the impact of colour ...

    • Exploring possibilities for GitLab as a Learning Management System 

      Sellevåg, Nicholas Bodvin; Senko, Yan; Kongelf, Fabian; Borge-Jensen, Oddbjørn S. (Bachelor thesis, 2022)
      Bachelor oppgaven er utført som et eksperiment for å utforske muligheter ved å bruke Gitlab som en Læringsstyrringssplattform (LMS). Det er en rekke utfordringer tilknyttet hva LMS tilstreber å tilby. Erik Hjelmås, ...

    • Innovative methods for large-scale fingerprint identification systems - Facilitating searching in a large-scale database 

      Li, Guoqiang (Doctoral theses at NTNU;296, Doctoral thesis, 2016)
      Fingerprint recognition has gained wide acceptance and great popularity after the fingerprint recognition based applications have been adopted in diverse scenarios, such as forensics area (mainly by law enforcement agencies), ...

    • Managing private credentials by privacy-preserving biometrics 

      Yang, Bian; Li, Guoqiang (Journal article; Peer reviewed, 2018)
      We investigate in this paper the need to managing a user’s private credentials using privacy-preserving biometrics, define several private credential management work models under different trust models between a user and ...

    • Morphing Attack Detection-Database, Evaluation Platform, and Benchmarking 

      Raja, Kiran; Ferrara, Matteo; Franco, Annalisa; Spreeuwers, Luuk; Batskos, Ilias; Wit, Florens de; Gomez-Barrero, Marta; Scherhag, Ulrich; Fischer, Daniel; Venkatesh, Sushma; Singh, Jag Mohan; Li, Guoqiang; Bergeron, Loïc; Isadskiy, Sergey; Ramachandra, Raghavendra; Rathgeb, Christian; Frings, Dinusha; Seidel, Uwe; Knopjes, Fons; Veldhuis, Raymond N.J.; Maltoni, Davide; Busch, Christoph (Peer reviewed; Journal article, 2021)
      Morphing attacks have posed a severe threat to Face Recognition System (FRS). Despite the number of advancements reported in recent works, we note serious open issues such as independent benchmarking, generalizability ...

    • Multi-feature Multimodal Biometric Recognition Based on Quaternion Locality Preserving Projection 

      Wang, Zhifang; Zhen, Jiaqi; Li, Yanchao; Li, Guoqiang; Han, Qi (Peer reviewed; Journal article, 2019)
      This paper proposed Quaternion locality preserving projection (QLPP) for multi-feature multimodal biometric recognition. Multi-features fill the real part or the three imaginary parts of quaternion to constitute the ...

    • Multimodality for Reliable Single Image Based Face Morphing Attack Detection 

      Ramachandra, Raghavendra; Li, Guoqiang (Peer reviewed; Journal article, 2022)
      Face morphing attacks have demonstrated a high vulnerability on human observers and commercial off-the-shelf Face Recognition Systems (FRS), especially in the border control scenario. Therefore, detecting face morphing ...

    • Negotiating Privacy Settings in Homecare through Android Applications 

      Moen, Runar; Godana, Abdurahman (Bachelor thesis, 2022)
      Fra 2019 til 2021 har bruken av e-helsetjenester her i Norge økt med 13%. Dette har selvfølgelig fulgt med mange fordeler, men bringer også noen personvernspørsmål for både pasienter og omsorgspersonene som jobber dem. ...
