  1. 1. Wi-Fi fingerprinting as a mean to measure building occupancy : A case study in an office environment

    University essay from KTH/Transportplanering

    Author : Johan Bexhorn; Karl Kvarnefalk; [2023]
    Keywords : Wi-Fi tracking systems; Wi-Fi fingerprinting; footfall analytics;

    Abstract : The task of collecting visitor data in an indoor environment and therein determining the occupancy of a building is an extensive task. Conventional methods are expensive, time-consuming, and often lack the ability to produce data in longer time series. Further, they often require disruption of the studied area as equipment must be deployed. READ MORE

  3. 2. Impact of fixed-rate fingerprinting defense on cloud gaming experience

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Kent Thang; Adam Nyberg; [2023]
    Keywords : cloud gaming; QoE; QoS; proxy; fingerprinting defense; website fingerprinting attack;

    Abstract : Cloud gaming has emerged as a popular solution to meet the increasing hardware de-mands of modern video games, allowing players with dated or non-sufficient hardwareto access high-quality gaming experiences. However, the growing reliance on cloud ser-vices has led to heightened concerns regarding user privacy and the risk of fingerprintingattacks. READ MORE

  4. 3. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jessica Ye; Johan Lesko; [2023]
    Keywords : ;

    Abstract : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. READ MORE

  5. 4. Validation of Simultaneous T1 and T2 Mapping Using Cardiac Magnetic Resonance Fingerprinting in Self-Constructed Phantoms : An Analysis of the Reproducibility and Accuracy

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sasithon Meesan; [2023]
    Keywords : Cardiac Magnetic Resonance Fingerprinting cMRF ; Cardiac Magnetic Resonance Imaging CMR ; Simultaneous T1 and T2 Mapping; Validation; Accuracy; Reproducibility; Cardiac Magnetic Resonance Fingerprinting cMRF ; Kardiovaskulär Magnetresonans CMR ; Simultant T1 och T2 Parametrisk-Karaktärisering; Validering; Noggrannhet; Reproducerbarhet;

    Abstract : Quantitative cardiac magnetic resonance imaging (CMR) has gained traction within both the clinical and research field due to high prevalence of cardiovascular diseases. Cardiac magnetic resonance fingerprinting (cMRF) is a novel approach introduced to address the limitation associated with evaluation of multiparametric quantitative CMR. READ MORE

  6. 5. Virtual Reality over the Internet : An experimental study of common countermeasures when using VR applications over the Internet

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Max Wetterström; Patric Rönn; [2023]
    Keywords : Virtual Reality; VR; Padding; Delay; VPN; QoS; QoE; Countermeasures; Cybersecurity; Fingerprinting; Traffic Analysis;

    Abstract : Currently, there is a lack of research behind the security of Virtual Reality against fingerprinting attacks and how these affect the Quality of Experience (QoE) and Quality of Service (QoS) for a user. With practical testing in a game which implements traffic shaping methods as security defences, this thesis aims to take the first step towards changing this. READ MORE
