Abschlussarbeiten im Bereich Human-Centered Security and Privacy
Below you will find focus areas in the research field "Human-Centered Security and Privacy" for which we offer Bachelor's and Master's theses. For a specific topic and any questions about these focus areas, please contact the relevant person. Public Security User InterfacesThe rapid development of digital technologies and the increasing threat of cybersecurity have led to a growing need for innovative security solutions in public spaces. One example of user interfaces that can improve security behavior are so-called Public Security User Interfaces. These are interfaces positioned in shared, non-personal areas that offer information or interactions on security-related topics. These interfaces play an important role in providing security information, improving situational awareness, and promoting secure behavior. The main goal of this research is to investigate the design, implementation, and impact of user interfaces that enhance security behavior, in order to facilitate the transition from cybersecurity awareness to habitual secure behavior. The theses in this area deal with topics such as:

Social EngineeringCybercrime currently causes a global economic loss amounting to several trillion euros. According to expert analyses, up to 90% of these damages are a direct or indirect result of attacks in which the human element is at the center. Attackers exploit authority, fear, curiosity, or helpfulness with the goal of manipulating their victims to obtain sensitive data. Examples include phone calls to obtain user login credentials, emails containing malware attachments to gain access to protected networks, or deep fakes used to impersonate someone's identity. Theses in this area address a variety of questions:

Security and Privacy in Mixed RealityMixed reality devices are quickly finding their way into usersâ daily lives, particularly in the form of head-mounted displays. Users can immerse themselves in virtual worlds or enrich the virtual world with physical content, supporting a wide range of applications in the areas of entertainment, work, education, and well-being. While these technologies support an ever-increasing number of features in the aforementioned areas, they also present challenges and create opportunities for security and privacy. Theses in this area essentially deal with topics in the context of two general questions: (1) How can mixed reality solve existing challenges in terms of privacy and security? (2) What challenges in terms of privacy and security arise in the context of mixed reality, and how can these be addressed? Recommended knowledge and interests

On-Body Security and Privacy InterfacesThe rapid integration of wearable sensors and head-mounted displays (HMDs) makes on-body computing increasingly relevant for security and privacy research. In this area, we focus on biometric authentication, privacy-preserving wearables, physiological sensing, and secure interaction paradigms for augmented reality (AR) and virtual reality (VR). Possible topics include the development of novel authentication methods for wearable devices, privacy-preserving approaches to continuous physiological monitoring, secure interaction concepts in AR and VR environments, and adaptive security/privacy mechanisms that enhance user trust and system reliability. By addressing current challenges and future opportunities, we aim to develop resilient, privacy-conscious, and user-friendly on-body systems that prioritize both security and seamless interaction experiences.

Tangible Security and Privacy User InterfacesIn the age of ubiquitous computing, users' IT security and privacy are at risk almost anytime. IT security and privacy assistants help users become aware of these risks and take appropriate measures to protect their data. However, these systems are often too complex, unintuitive, and not visually appealing. In order to enable even less technologically savvy or inexperienced individuals to use IT security and privacy assistants, such mechanisms must become tangible, i.e., physically manipulable and touchable by humans.

Behavioral BiometricsThe use of biometric mechanismsâi.e., authentication based on unique features of a user's physiology or behaviorâis a convenient and fast alternative to classical token- or knowledge-based authentication. Popular examples include fingerprint, facial recognition, or typing behavior biometrics. However, these systems typically rely on machine learning algorithms, making their decisions both difficult for the user to comprehend and subject to manipulation. In this research area, we investigate novel approaches that enable users to understand and influence the results of biometric (black-box) systems, and develop new approaches with a focus on the user. The following questions are particularly interesting:
Concrete research approaches include, among others, investigating (real) user behavior (e.g., through observations, interviews, surveys) and designing, implementing, and evaluating novel security and privacy concepts. Recommended knowledge and interests

Design of a Virtual Reality Adaptive System based on Electrodermal Activity phasic components
DescriptionElectrodermal activity (EDA) denotes the measurement of continuous changes in the electrical conductance properties of the skin in response to sweat secretion by the sweat glands. EDA is autonomously modulated by sympathetic nervous system (SNS) activity, a component of the autonomic nervous system (ANS), which is involved in the control of involuntary bodily functions as well as cognitive and emotional states. Specifically, phasic EDA activity correlated with stress, cognitive load, and attention orienting. Therefore, measuring phasic EDA responses can give us information about the user's state.In this thesis project, we want to develop an adaptive system that modifies the visual complexity of the VR environment based on changes in phasic EDA. Specifically, we want to use new signal processing methodologies termed adaptive thresholding and gaussian filtering.The research consists of three main stages: (1) validation of the psychophysiological inference underpinning the adaptive system (2) implementation of a working VR prototype, and (3) an evaluation of the adaptive environment.

Physiologically adaptive MR Blending
DescriptionMixed reality (MR) systems refer to the entire broad spectrum that ranges from physical to virtual reality (VR). It includes instances that overlay virtual content on physical information, i.e., Augmented Reality (AR), and those that rely on physical content to increase the realism of virtual environments, i.e., Augmented Virtuality (AV). Such instances tend to be pre-defined for the blend of physical and virtual content. To what extent can MR systems rely on physiological inputs to infer user state and expectations and, in doing, adapt their visualization in response? Measurement sensors for eye and body motion, autonomic arousal (e.g., respiration, electrodermaland heart activity), and cortical activity (e.g., EEG, fNIRS) are widely used in psychological and neuroscience research to infer hidden user states, such as stress, overt/covert attention, working memory load, etc.However, it is unclear if such inferences can serve as useful real-time inputs in controlling the presentation parameters of MR environments.In this thesis project, we will investigate whether this blend can be adaptive to user states, which are inferred from physiological measurements derived from gaze behavior, peripheral physiology (e.g.., electrodermal activity (EDA); electrocardiography (ECG)), and cortical activity (i.e.., electroencephalography (EEG)). In other words, we will investigate the viability and usefulness of MR use scenarios that vary in their blend of virtual and physicalcontent according to user physiology. In particular, we will focus on understanding how physiological readings can passively determine the appropriate amount ofvisual information to present within an MR system. You will

Evaluation of an Adaptive VR environment that Uses EEG Measures as Inputs to a Biocybernetic Loop
DescriptionBiocybernetic adaptation is a form of physiological computing where real-time physiological data from the brain and the body can be used as an input to adapt the user interface. In this way, from the physiological data, we can infer the userâs state and design implicit interactions in VR to change the scene to support certain goals. This thesis aims the develop and evaluate an adaptive VR environment designed to maximize users' performance by exploiting changes in real-time electroencephalography (EEG) to adjust the level of visual complexity. The research consists of three main stages: (1) validation of the input EEG measures underpinning the loop; (2) implementation of a working VR prototype; and (3) an evaluation of the adaptive environment. Specifically, we aim to demonstrate the sensitivity of EEG power in the (frontal) theta and (parietal) alpha bands to adapt levels of visual complexity. You will

Modulating distraction by adapting the perceptual load: implementation of a biocybernetic loop to support performance and prevent distraction
DescriptionResearch from cognitive science and computerized displays of simple stimuli has shown how perceptual load is a critical factor for modulating distraction. Perceptual load is the amount of information involved in processing task stimuli. According to Lavie (1995), our attentional resources are limited and mainly directed towards task-relevant goals, but we might be more prone to distractors if we have cognitive spare resources. Previous research showed that human faces have bigger distracting power than non-face objects. This project aims to assess the distracting potential distracting effect of human avatars in a social VR scenario. We aim to transfer of traditional paradigms that assess attention and distraction to immersive VR. Lastly, we adapt the target-distractor recognizability to evaluate if a physiologically-adaptive system that optimizes for perceptual load can support task performance. The research consists of three main stages: (1) validation of the psychophysiological inference underpinning the physiological loop (2) implementation of a working VR prototype, and (3) an evaluation of the adaptive environment.

Design of a physiological loop settled in a Social VR scenario to support task performance and user experience
DescriptionPhysiological computing is a multidisciplinary research field in HCI wherein the interaction depends on measuring and responding to the user's physiological activity in real-time (Fairclough, 2009). Physiological computing allows for implicit interaction; by monitoring the physiological signals of the user, the computer can infer, e.g., if the task demands are either too challenging or easy, and either adapt the difficulty level or when users are getting distracted from the task, the system could give them a notification. Measuring the psychological state of the user creates intriguing possibilities for Social VR scenarios as we can either adapt the number of displayed avatars, their form or even their proxemic distance. This thesis aims the develop an adaptive Social VR environment designed to support users' performance when engaged in a cognitive task using a measure of physiological state (electrodermal activity: EDA) as input for adaptation. The research consists of three main stages: (1) validation of the psychophysiological inference underpinning the physiological loop (2) implementation of a working VR prototype, and (3) an evaluation of the adaptive environment.

Designing and Evaluating Mixed Reality Transition Visualizations
DescriptionPrior work has explored transition visualizations between VR environments, or on specific interaction techniques for transferring objects from VR <-> AR views. However, there has been less attention on what are the more effective transitions across the reality-virtuality continuum. The focus of this work would be to (a) identify suitable MR transitions (b) create a mapping to common tasks where such transitions may be applicable (e.g., keyboard typing) (c) prototype different transitions, from R-->AR-->AV--VR, and vice versa: VR-->AV-->AR--R, and empirically investigating different parameters of each (d) run a user evaluation to assess perceived UX. comfort, sickness, etc. This project extends the work in Keep it simple? Evaluation of Transitions VR, by exploring MR transitions, instead of only across different VR environments. Evaluation metrics will involve both objective and subjective measures. RQ1: What are the most effective methods for transitioning users across the reality-virtuality spectrum? RQ2: How do these transition visualizations influence user experience, user physiological state, workload, and acceptance across tasks? You will

Offline QKD II - Perceived vs. "Real" Security
Imagine Bob's office is connected via a (quantum-)encrypted connection to a server. How could Bob access this server from his home office if he does not have the necessary hardware at home? Well, he could get keys in his office and save them on his personal key-safe token. He could subsequently use the token at home and connect to the server. The topic of offline distribution of cryptographic keys is interesting for researchers and practitioners alike, even outside the QKD context. Your thesis would evolve around the evaluation of already existing consumer devices that could be used to store and transport QKD-keys (or symmetric cryptographic keys in general). Details |

Adaptive RSVP System Based on Pupil Dilation
Description Project Overview Project MotivationTraditional RSVP systems often rely on fixed speeds or manual adjustments, which may not suit every user's cognitive capacity. This project seeks to enhance user engagement and efficiency by using real-time pupil dilation data to adjust the speed and presentation style dynamically. By doing so, the RSVP system can become more responsive to individual reading habits, reducing cognitive overload and improving comprehension and retention of information. This work has important implications for accessibility, enabling better interaction for users with reading difficulties or neurological impairments. Project GoalsThis thesis will explore the development and evaluation of an adaptive RSVP system, with a focus on the following key objectives:

Investigating Gaze Estimation Accuracy in Collaborative Virtual Environments (CVEs)
DescriptionProject OverviewThis thesis project offers an exciting opportunity for students to contribute to cutting-edge research on gaze estimation in interactive systems. The focus is on enhancing the accuracy of gaze interpretation within Collaborative Virtual Environments (CVEs), where effective communication is often dependent on understanding where participants are looking. Gaze serves as a vital non-verbal communication cue, yet people frequently struggle to accurately determine another persons gaze direction (i.e., where someone is looking), especially over distances. Project MotivationIn CVEs, precise gaze estimation is crucial for natural and effective interaction. While previous research has explored distant pointing as an interaction mechanism, this project shifts focus to gaze estimation. By addressing common inaccuracies in gaze prediction, this research aims to significantly improve how users interpret each others gaze during virtual interactions, ultimately enhancing the overall immersive experience.Project GoalsThis thesis will investigate how accurately gaze estimation can be performed in CVEs, focusing on two main aspects:

Design of a Study-Tool to Collect Context-Based Probes
BackgroundProbes are a powerful and widely used method in Human-Computer Interaction (HCI) and related disciplines such as social sciences. They enable researchers to gather rich, contextual insights into participantsâ lived experiences, uncovering underlying needs, emotions, intentions, and desires. By prompting participants to repeatedly reflect on and document specific aspects of their daily lives â often in the form of diary entries â researchers can gain a nuanced, reliable understanding of what truly matters to participants. This depth of insight is essential for the design of applications that are not only user-centered but also contextually relevant and personally meaningful. It is inherent that probes are easy and engaging for the participants, while at the same time they are supposed to include multiple data types, such as written text, photos, log data, drawings, audio or video recordings and individual designs. With the growing importance of context-adaptive applications, there is an increasing need to investigate well-defined situations based on human and environmental context factors (e.g., location, activity, intentions, cognitive states, and emotions). Existing tools often lack the ability to effectively prompt participants to respond within these specific contexts. Thesis GoalThe objective of this thesis is to design and develop a mobile application that functions as an innovative and engaging probe tool. It should support the collection of diverse data formats, including photos, videos, audio, and creative user inputs such as sketches or prototypes. Additionally, the application should utilize contextual triggers (e.g., location data, physiological data from smartwatches) to send timely notifications prompting users to provide input. You will

Assessing Image Similarity via EEG
DescriptionProject OverviewFor human-in-the-loop (HITL) systems, it is important to understand and quantify usersâ perceptions to make the next predictions inline with the userâs intention. HITL systems that employ visual recognition often require inferring similarity between a percieved object and a mental targed. This is often difficult to determine when it comes to complex stimuli like faces. While HITL systems traditionally rely on explicit user input, implicit EEG responses can support the decision-making process effortlessly. Project GoalsIn this project, we will be exploring brain signals (more accurately, ERP components) in similariy prediction for visual stimuli.

Visualizing the Expert's Perspective in Extended Reality
Master Thesis Start Date: Flexible Supervisor: Clara Sayffaerth (clara.sayffaerth@um.ifi.lmu.de) OverviewThis project aims to explore how different Extended Reality (XR) visualizations of an expert's perspective impact learning and memory retention. With more people retiring from the workforce than entering it, combined with the rapid evolution of technology, transferring practical and procedural knowledge has become increasingly challenging. Currently, this transfer often relies on in-person demonstrations, which can be limiting. XR technology offers solutions by enabling learning that is not restricted by time or place while also presenting information in an immersive, three-dimensional way. Additionally, XR allows us to visually adapt reality. By experimenting with how a virtual expert is visualized, we can go beyond replicating realistic instructions. These adaptations have the potential to enhance the learning experience and improve knowledge transfer for future learners. Objectives
