Automating Security Audit Using Large Language Model based Agent: An Exploration Experiment
In the current rapidly changing digital environment, businesses are under constant stress to ensure that their systems are secured. Security audits help to maintain a strong security posture by...
AI-Driven IRM: Transforming insider risk management with adaptive scoring and LLM-based threat detection
Insider threats pose a significant challenge to organizational security, often evading traditional rule-based detection systems due to their subtlety and contextual nature. This paper presents an...
Fusion Based Hand Geometry Recognition Using Dempster-Shafer Theory
This paper presents a new technique for person recognition based on the fusion of hand geometric features of both the hands without any pose restrictions. All the features are extracted from...
Offline Handwritten Signature Verification Using a Stream-Based Approach
Handwritten Signature Verification (HSV) systems distinguish between genuine and forged signatures. Traditional HSV development involves a static batch configuration, constraining the system's...
PassTSL: Modeling Human-Created Passwords through Two-Stage Learning
Textual passwords are still the most widely used user authentication mechanism. Due to the close connections between textual passwords and natural languages, advanced technologies in natural...
Access Controlled Website Interaction for Agentic AI with Delegated Critical Tasks
Recent studies reveal gaps in delegating critical tasks to agentic AI that accesses websites on the user's behalf, primarily due to limited access control mechanisms on websites designed for...
Semi-Supervised RF Fingerprinting with Consistency-Based Regularization
As a promising non-password authentication technology, radio frequency (RF) fingerprinting can greatly improve wireless security. Recent work has shown that RF fingerprinting based on deep...
MLP-Hash: Protecting Face Templates via Hashing of Randomized Multi-Layer Perceptron
Applications of face recognition systems for authentication purposes are growing rapidly. Although state-of-the-art (SOTA) face recognition systems have high recognition accuracy, the features...
VoxAtnNet: A 3D Point Clouds Convolutional Neural Network for Generalizable Face Presentation Attack Detection
Facial biometrics are an essential components of smartphones to ensure reliable and trustworthy authentication. However, face biometric systems are vulnerable to Presentation Attacks (PAs), and...
Cyri: A Conversational AI-based Assistant for Supporting the Human User in Detecting and Responding to Phishing Attacks
This work introduces Cyri, an AI-powered conversational assistant designed to support a human user in detecting and analyzing phishing emails by leveraging Large Language Models. Cyri has been...
PAFedFV: Personalized and Asynchronous Federated Learning for Finger Vein Recognition
With the increasing emphasis on user privacy protection, biometric recognition based on federated learning have become the latest research hotspot. However, traditional federated learning methods...
Weakly Supervised Training for Hologram Verification in Identity Documents
We propose a method to remotely verify the authenticity of Optically Variable Devices (OVDs), often referred to as ``holograms'', in identity documents. Our method processes video clips captured...
A Large-Scale Survey of Password Entry Practices on Non-Desktop Devices
Password managers encourage users to generate passwords to improve their security. However, research has shown that users avoid generating passwords, often giving the rationale that it is...
"I Apologize For Not Understanding Your Policy": Exploring the Specification and Evaluation of User-Managed Access Control Policies by AI Virtual Assistants
The rapid evolution of Artificial Intelligence (AI)-based Virtual Assistants (VAs) e.g., Google Gemini, ChatGPT, Microsoft Copilot, and High-Flyer Deepseek has turned them into convenient...
Personalized Guidelines for Design, Implementation and Evaluation of Anti-phishing Interventions
Background: Current anti-phishing interventions, which typically involve one-size-fits-all solutions, suffer from limitations such as inadequate usability and poor implementation. Human-centric...
Trustworthiness of $\mathbb{X}$ Users: A One-Class Classification Approach
$\mathbb{X}$ (formerly Twitter) is a prominent online social media platform that plays an important role in sharing information making the content generated on this platform a valuable source of...
Signature Verification using Geometrical Features and Artificial Neural Network Classifier
Signature verification has been one of the major researched areas in the field of computer vision. Many financial and legal organizations use signature verification as access control and...
Evaluating the Security and Privacy Risk Postures of Virtual Assistants
Virtual assistants (VAs) have seen increased use in recent years due to their ease of use for daily tasks. Despite their growing prevalence, their security and privacy implications are still not...
