How Do Dual Tasks Affect Id Verification? A Mobile Eye-Tracking Analysis, Nathan Wieters
How Do Dual Tasks Affect Id Verification? A Mobile Eye-Tracking Analysis, Nathan Wieters
Masters Theses (Archived)
ID screening is a two-part process — the card and identity must be authenticated. Psychological research has typically focused on identity verification without considering card verification. To fill this gap, the present study had participants complete an ID verification task while wearing eye-tracking glasses to record gaze behavior during face-matching decisions. After 2 practice trials, a research assistant presented 48 physical ID cards with embedded facial images, one at a time, beside a computer monitor that presented a facial videos and calendar date. Participants were asked to decide if the ID card was valid on a 6-option scale from Definitely …

Artificial Intelligence (Ai) In Forensic Psychology: An Umbrella Review Of Potentials And Pitfalls, Ysabel Thereze Ang Guevarra, Nur Eva Alisha Binte Mohamed Hisham, Andree Hartanto
Research Collection School of Social Sciences
Artificial intelligence (AI) is becoming increasingly embedded within forensic psychological practice, shaping how criminal risk, legal responsibility and public safety are assessed. AI tools are now used in recidivism prediction, behavioural analysis, deception detection and investigative support, high-stakes domains where errors can have profound consequences. Despite this rapid adoption, the existing literature remains fragmented, with most reviews confined to narrow subdomains and offering limited integrated synthesis of AI′s broader role in forensic psychology. Thus, this umbrella review addresses this gap by synthesising findings from 43 reviews obtained from five major databases, namely EBSCOhost ERIC, EBSCOhost PsycInfo, PubMed, Scopus and Web …

The Role Of Online Disinhibition On Social Media Users' Privacy Concerns And Behaviors, Lisa Thompson, Sinyong Choi
The Role Of Online Disinhibition On Social Media Users' Privacy Concerns And Behaviors, Lisa Thompson, Sinyong Choi
Faculty Articles
As social media platforms become central to digital interactions, concerns about both privacy and the disclosure of personal information have evolved. Online disinhibition—the psychological detachment users experience in digital spaces that distance their online behaviors from offline consequences—may shape perceptions of privacy risks, particularly on social media platforms like TikTok. This study examines the relationships between online disinhibition and users’ privacy concerns and protective behaviors while accounting for individuals’ sense of gratification, media awareness, identity, and experience. By exploring dimensions such as anonymity and invisibility, we investigate how these factors are linked to self-disclosure and diminished privacy caution. Findings from …

Method For Trust-Aware And Language Model–Driven Email Threat Detection And Mitigation, Niranjan M M
Method For Trust-Aware And Language Model–Driven Email Threat Detection And Mitigation, Niranjan M M
Defensive Publications Series
Email remains the primary communication channel for enterprises and continues to be the most exploited attack vector for cyber threats. Modern email attacks increasingly rely on impersonation, social engineering, and contextual manipulation rather than traditional malware or malicious links, allowing them to evade existing detection mechanisms. At the same time, email security systems are adopting large language models (LLMs) to improve intent detection and contextual analysis, introducing new risks where email content itself can manipulate or degrade automated reasoning.
The proposal introduces a secure, trust-aware, and LLM-safe framework for automated email threat detection and remediation. The proposed system integrates sender …

Impartial Intelligence? Evidence Of Country-Label Sensitivity In Ai Financial Analysis, Fabio Motoki, Jedson Pinto
School of Accountancy Faculty Publications
This study examines whether large language models exhibit systematic country-contingent differential treatment in financial fraud detection. Analyzing 30,000 synthetic transactions with identical statistical properties across three country attributions (United States, Great Britain, and China), we find LLMs assign significantly higher fraud probabilities to Chinese-attributed transactions (36.2%) compared to Western countries (≈30–31%), resulting in accuracy disparities of 67% versus 74%. The gap remains stable across five independent experimental replications and persists when using Chinese language prompts, ruling out linguistic effects. Bias mitigation strategies, such as requiring explanations or explicit country neutrality instructions, reduce but fail to eliminate these disparities. Testing across …

Building Trustworthy Information Systems: A Unified Framework For Comparative Risk Detection, Parisa Momeni
Building Trustworthy Information Systems: A Unified Framework For Comparative Risk Detection, Parisa Momeni
USF Tampa Graduate Theses and Dissertations
Risk detection in large scale information systems increasingly depends on heterogeneous data generatedby both centralized and distributed ecosystems. While centralized systems provide curated and validated reports, distributed environments produce large-scale and real-time observational evidence. Existing computational approaches analyze these ecosystems in isolation, limiting systematic comparison of risk repre-sentations across heterogeneous sources.
This dissertation presents a unified computational framework for comparative risk detection across centralized and distributed information systems. The framework provides a domain independent methodology for transforming heterogeneous risk reporting data into comparable multidimensional representations. To enable interpretable comparison of heterogeneous risk distributions, this work introduces the Geometric Overlap Score …

Agentic Ai Approach For Online Financial Fraud Detection, Shadi Saleh, Kelechi Osuji, Wolfram Hardt
Al-Farahidi Expert Systems Journal
As digital payment systems facilitate billions of transactions every day, there is a high probability of fraudulent activities in these systems. Traditional fraud detection systems, including rule-based systems and machine learning-based systems, have three major limitations: lack of explainability in terms of regulatory requirements, lack of contextual reasoning in terms of rare behavioral patterns, and lack of interaction with human experts in fraud analysis. This paper proposes a novel agentic framework in fraud detection systems by integrating Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG) in context-aware reasoning based on historical transaction evidence. The framework is designed as a system …
Extending Unibreak: Semantic Retrieval And Harmful-Intent Direction Suppression For Token-Level Llm Jailbreaking, Sanket Saha
Extending Unibreak: Semantic Retrieval And Harmful-Intent Direction Suppression For Token-Level Llm Jailbreaking, Sanket Saha
Master’s Dissertations
Token-level adversarial perturbations remain one of the most efficient known attacks against the safety alignment of instruction-tuned large language models (LLMs). Among recent works, the UniBreak framework (You et al., 2026) stands out for unifying gradient-based optimization with an evolutionary perturbation repository. However, its repository relies solely on accumulated success frequency without utilizing query content, and its fitness function implicitly assumes that suppressing refusal tokens is sufficient to elicit harmful responses. In this dissertation, we extend UniBreak along both axes and re-evaluates the framework under stricter generalization and judgment protocols. Specifically, we introduce a semantic perturbation repository that replaces frequency-only …
Techniques For Preventing Anchoring Bias In Ai Investigative Analysis Through Staged Data Redaction And Hypothesis-Gated Revelation, Avneet Singh Chhabra
Techniques For Preventing Anchoring Bias In Ai Investigative Analysis Through Staged Data Redaction And Hypothesis-Gated Revelation, Avneet Singh Chhabra
Defensive Publications Series
Presented herein is a system for preventing anchoring bias in large language model (LLM) investigative analysis. Bias in LLMs is not typically addressed by instruction-level approaches; rather, it is most effectively mitigated by physically separating the biasing data from an LLM's input during the hypothesis formation phase. The proposed system includes five core components: a Data Redaction Engine, a Staged Analysis Protocol, a Structural Gate, a Corrections Bridge, and a Procedural Attestation Record. The Data Redaction Engine operates to separate source data into a redacted evidence set and an attribution set, validated by a multi-layer validation pass. The Staged Analysis …
Evaluating Legal Frameworks For The Protection Of Consumers Of Digital Financial Services: Global Trends And Their Significance For Vietnam, Ha Son Nguyen, Lanh Dinh Cao, Nguyen Dinh Phan
Evaluating Legal Frameworks For The Protection Of Consumers Of Digital Financial Services: Global Trends And Their Significance For Vietnam, Ha Son Nguyen, Lanh Dinh Cao, Nguyen Dinh Phan
International Journal on Consumer Law and Practice
The development of digital financial services (DFS) in the context of global digital transformation poses fundamental challenges for the legal framework for consumer protection, particularly in developing countries such as Vietnam. This article argues that the sectoral approach currently adopted in Vietnam, with rules dispersed across various specialized statutes, has created a structurally significant legal gap, a lack of consistency in protection standards, and limitations on effective coordination among regulatory authorities. It thereby undermines the law’s capacity to protect consumers in the highly cross-sectoral environment of digital finance.
Through an analytical and comparative approach that draws on the experiences of …
Adaptive Outlier Detection Over Data Stream, Rui Zhu, Mingyuan Jiang, Xiaochun Yang, Baihua Zheng, Bin Wang, Tao Qiu
Adaptive Outlier Detection Over Data Stream, Rui Zhu, Mingyuan Jiang, Xiaochun Yang, Baihua Zheng, Bin Wang, Tao Qiu
Research Collection School Of Computing and Information Systems
Continuous distance-based outlier detection in streaming data poses significant challenges and has a wide range of practical applications. Traditional threshold-based methods perform well under stable streaming conditions, where fixed parameters remain effective. However, they often struggle with dynamic data distributions and high stream speeds, leading to suboptimal performance, limited control over the number of returned outliers, and failure to meet real-time detection requirements. To address these issues, this paper introduces a novel Recall and Proportion-Aware Outlier Detection (RPA-OD) query. In RPA-OD, ρ defines a distance relaxation that enables real-time outlier detection. Specifically, objects with fewer than k neighbors within the …

Online Shopping Non-Adoption In South Africa: A Distrust-Centric Framework Integrating Social Exchange, Trust Transfer, And Social Presence Theories, Cleopatra Moipone Matli, Jeevarathnam P. Govender
Journal of Marketing and Consumer Behaviour in Emerging Markets
Online shopping non-adoption remains critically underexplored, especially in emerging markets. Addressing this gap, the authors develop and test a distrust-centric framework that applies the inhibitory logic of social exchange, trust transfer, and social presence theories to explain pre-emptive avoidance. Focusing on South Africa, where only 18.16% of the population engage in e-commerce, data was collected from 414 consumers who have never shopped online. Structural equation modelling reveals that perceived lack of reciprocity directly increases the intention of non-adoption. Moreover, distrust in online payment systems transfers to broader channel scepticism, which in turn drives avoidance. Perceived lack of social presence further …
