Action-Independent Generalized Behavioral Identity Descriptors for Look-alike Recognition in Videos
Khodabakhsh, Ali; Loiselle, Hugo (Chapter, 2020)There is a long history of exploitation of the visual similarity of look-alikes for fraud and deception. The visual similarity along with the application of physical and digital cosmetics greatly challenges the recognition ... -
Automated Authentication of Audiovisual Contents: A Biometric Approach
Khodabakhsh, Ali (Doctoral theses at NTNU;2021:213, Doctoral thesis, 2021)Following the introduction of image manipulation tools such as Adobe Photoshop in the early 2000s, the public trust in image authenticity dropped and the need for the development and deployment of image authentication ... -
A Generalizable Deepfake Detector based on Neural Conditional Distribution Modelling
Khodabakhsh, Ali; Busch, Christoph (Chapter, 2020)Photo- and video-realistic generation techniques have become a reality following the advent of deep neural networks. Consequently, there are immense concerns regarding the difficulty in differentiating what content is real ... -
Identifying keys using acoustic emanations from keystrokes
Nakken, Nicolai (Master thesis, 2023)Tidligere forskining har vist det er mulig å rekonstruere tekst skrevet på tastatur ved å analysere lyden som blir laget. Dette indikerer en stor sikkerhetstrussel, og et behov for videre forsking. I denne masteoppgaven ... -

Subjective Evaluation of Media Consumer Vulnerability to Fake Audiovisual Content
Khodabakhsh, Ali; Ramachandra, Raghavendra; Busch, Christoph (Chapter, 2019)Facilitation of fake face generation in recent years, thanks to advancements in computer graphics and artificial intelligence, raises concerns about malicious use of these techniques for personal or political gains. Media ... -
Subjective Versus Objective Face Image Quality Evaluation For Face Recognition
Khodabakhsh, Ali; Pedersen, Marius; Busch, Christoph (Chapter, 2019)The performance of any face recognition system gets affected by the quality of the probe and the reference images. Rejecting or recapturing images with low-quality can improve the overall performance of the biometric system. ... -
Unit-Selection Based Facial Video Manipulation Detection
Nielsen, Thomas; Khodabakhsh, Ali; Busch, Christoph (Chapter, 2020)Advancements in video synthesis technology have caused major concerns over the authenticity of audio-visual content. A video manipulation method that is often overlooked is inter-frame forgery, in which segments (or units) ...
