Comparison of classification methods for perspiration-based liveness algorithm
… Fingerprint scanners may be susceptible to spoofing using artificial materials, or in the worst case, dismembered fingers. Liveness, i.e. to determine whether the introduced biometric is coming from a live source, has been suggested as a means to circumvent attacks that use spoof fingers. It …

Authenticating a Known User Through Behavioral Biometrics Using a Smartphone Accelerometer
… “MATLAB Mobile App,” and introducing noise to spoof the known user.

RESILIENT STATE ESTIMATION FOR MICRO AIR VEHICLES UNDER SENSOR ATTACKS
… the same physical signal. An adversary may spoof a subset of these sensors and send falsified readings to the controller, potentially compromising performance and safety of the system. This work integrates Brooks-Iyengar Sensor fusion algorithm with a generic state estimator as a method to …

Biometric Leakage from Generative Models and Adversarial Iris Swapping for Spoofing Eye-based Authentication
… trained on biometric data and explores digital spoofing attacks on iris-based authentication systems representative of AR/VR environments. We first explore how diffusion models trained on biometric data can memorize and leak iris images. Next, we evaluate the effectiveness of Cross-Attention …

Application-level distributed denial of service prevention in a replicated system
… even against malicious clients who are able to spoof additional IP addresses. It is also capable of accommodating HTTP proxies, which regularly provide many times more traffic than a single host. Such properties are desirable for package management servers and the like, whose responsiveness in …

Toward the Systematization of Active Authentication Research
… at login. This allows for authentication to be spoofed just once to gain access to an entire user session. Behaviometric protocols continuously consume a user’s behavior as a token of authentication and can be applied throughout a session, thereby eliminating a fixed token to spoof. Research …

Establishment of a Cyber-Physical Systems (CPS) Test Bed to Explore Traffic Collision Avoidance System (TCAS) Vulnerabilities to Cyber Attacks
… open-source software (GNU radio) where spoofing TCAS radio signals in now possible. This paper outlines a proposed threat model for several TCAS vulnerabilities from an adversarial perspective. Periodic and aperiodic attack models are explored as possible low latency solutions to spoof …

Ocular motion classification for mobile device presentation attack detection
… the art biometric methods remain vulnerable to spoof attacks. As these attacks become more sophisticated, ocular motion based presentation attack detection (PAD) methods provide a potential deterrent. This dissertation presents the methods and evaluation of a novel optokinetic nystagmus (OKN) …

Performance analysis of multimodal biometric fusion
… intra-class variability, non-universality, spoof attack and unacceptable error rates. Some of the challenges can be handled by designing a multimodal biometric system. Multimodal biometric systems are those which utilize or are capable of utilizing, more than one physiological or behavioural …

Real-time Adaptive Sensor Attack Detection and Recovery in Autonomous Cyber-physical Systems
… may non-invasively compromise sensors and spoof the controller to perform unsafe actions. This issue is even emphasized with the increasing autonomy in CPS. While this fact has motivated many defense mechanisms against sensor attacks, a clear vision of the timing and usability (or the false …

Design and theoretical analysis of advanced power based positioning in RF system
… fading, and disruption due to jamming and spoof. Hence, it is required to supplement GPS with inertial sensors and indoor localization schemes that make use of WiFi APs or beacon nodes. In the GPS-challenging or fault scenario, radio-frequency (RF) infrastructure based localization schemes …

Fusion of fingerprint presentation attacks detection and matching: a real approach from the LivDet perspective
… system cannot ignore the vulnerability to spoofing or presentation attacks (PAs), which must be addressed by effective countermeasures from the beginning of the design process. However, despite significant improvements, especially by adopting deep learning approaches to fingerprint …

Intrusion Detection using Bit Timing Characteristics for CAN Bus
… used for node identification. It is possible to spoof node A by sending the same identifier through node B and thereby control node A. Thus, a hacker can control the steering using the car's internal lights and render it ineffective or misuse them. In order to combat this, we try to fingerprint …

Moby Dick! The Musical: A Travesty In Travesti
… However, since Moby Dick! The Musical is a spoof that features a play within a play, many, if not most, of the roles are being played by women (teenage school-girls to be exact). These roles are known as "trouser roles," and this tradition stems back to the 17th Century. The term refers to a …

Matching optical coherence tomography fingerprint scans using an iterative closest point pipeline
… offer low security performance, are easy to spoof, and are unhygienic. Optical Coherence Tomography (OCT) is an emerging technology that allows a 3D volumetric scan of the finger surface and its internal microstructures. The junction between the epidermis and dermis - the internal fingerprint …

Detection and prevention of intrusions in power system cyber-physical infrastructure
… devices respond with real measurements, Raincoat spoofs measurements on behalf of offline devices. To spoof measurements that follow physical models of power systems, we include in Raincoat an algorithm that generates decoy measurements. Decoy measurements mislead attackers into designing (i) false …

Novel Devices for Terahertz Wave Imaging, Wave-guiding and Sensing
… We also exploited the capability of using the spoof surface plasmon to enhance the reflectivity of an interface between free space and a PPWG. We demonstrated that the reflection coefficient of this interface can be enhanced up to ~100 % at a designed frequency, by cutting a designed pattern of …
