Adversarial Activity Detection and Prediction Using Behavioral Biometrics
… activities of the users by recording their keystrokes audio. Using keystroke acoustics to predict typed text has significant advantages, such as being recorded covertly from a distance and requiring no physical access to the computer system. Recently, some studies have been done on keystroke …

Efficient and Verifiable Timing Channel Protection for Multi-Core Processors
… a practical timing channel attack to recover the keystrokes of a user in the commercial Amazon EC2 cloud. In this thesis, we explored new timing channel attacks and developed timing channel protection schemes for some of the hardware resources in a multi-core processor. Specifically, we discovered …

Accent Marks in L2 French: Keyboarding, Presentation Format, Working Memory, and Pronunciation Ability
… on delayed (one week later) posttests. Number of keystrokes had no effect on participant performance on posttests measures. When comparing treatment groups within each presentation format (word list or paragraph), these differences were only observed within the paragraph group. Additionally, …

Hardware and User Profiling for Multi-factor Authentication
… and readily available biometrics, e.g., user keystrokes. The aim is to improve the reliability of the authentication using a multi-factor approach without incurring additional cost or making the deployment of the solution overly complex. The presented approach in this research uses unique …

A Comparative Study of Novice vs. Experienced Pilots Utilizing Cockpit Models Applied to the Multi Function Display System
… flight information on the screen, the amount of keystrokes they used, and the time they needed to solve the problem. It was assumed the ICIS's highly structured organization and would effectively guide the user through the problem-solving process, with a significant improvement in human-computer …

Towards Integrated Audio-Visual Learning: From Vision-to-Audio Generation to a Unified Audio-Visual Framework
… For instance, musical notes can translate piano keystrokes into their corresponding sounds, and the rhythm of movement can connect dance videos to their accompanying music. The intermediate representation could also be derived from pre-trained deep learning models and act as semantic bridges to …

Cache-based side channels: Modern attacks and defenses
… an attacker can steal encryption keys, monitor keystrokes or reveal a user's personal information by leveraging the information derived from the side effects of a program's execution. These side effects include timing information, micro-architecture states, power consumption, electromagnetic …

Design and Analysis of Decoy Systems for Computer Security
… analysis to show the believability of simulated keystrokes when automated tools are used to distinguish them. Finally, we introduce and demonstrate an expanded role for decoys in educating users and measuring organizational security through experiments with approximately 4000 university students …

USER AUTHENTICATION ACROSS DEVICES, MODALITIES AND REPRESENTATION: BEHAVIORAL BIOMETRIC METHODS
<p>Biometrics eliminate the need for a person to remember and reproduce complex secretive information or carry additional hardware in order to authenticate oneself. Behavioral biometrics is a branch of biometrics that focuses on using a person’s behavior or way of doing a task as means of …
