Diverse Wi-Fi-based wireless applications have been proposed, ranging from daily activity recognition to vital sign monitoring. Despite their remarkable sensing accuracy, the high energy consumption and the requirement for customized hardware ...

In this paper, we proposed F²Key, the first earable physical security system based on commercial off-the-shelf headphones. F²Key enables impactful applications, such as enhancing voiceprint-based authentication systems, reliable voice assistants, audio ...

Virtual Reality (VR) technology, extensively utilized in gaming, social networking, and online collaboration, has raised significant security concerns due to the array of sensors integrated into VR headsets. This paper discusses several of our ongoing ...

Eggs and chickens serve as crucial animal-source proteins in our diets, making large-scale breeding egg incubation an essential undertaking. However, current solutions, i.e., vision-based and sensor-based methods, are primarily designed for egg fertility ...

Handwritten signature verification has become one of the most important document authentication methods that are widely used in the financial, legal, and administrative sectors. Compared with offline methods based on static signature images, online ...

The widespread deployment of unattended LoRa networks poses a growing need to perform Firmware Updates Over-The-Air (FUOTA). However, the FUOTA specifications dedicated by LoRa Alliance fall short of several deficiencies with respect to energy efficiency, ...

Recently, in-display fingerprint sensors have been widely adopted in newly-released smartphones. However, we find this new technique can leak information about the user's fingerprints during a screen-unlocking process via the electromagnetic (EM) side ...

Multi-port chargers, capable of simultaneously charging multiple mobile devices such as smartphones, have gained immense popularity and sold millions of units in recent years. However, this charging-targeted feature can also pose security and privacy ...

Recently, power banks for smartphones have begun to support wireless charging. Although these wireless charging power banks appear to be immune to most reported vulnerabilities in either power banks or wireless charging, we have found a new contactless ...

Radio-frequency (RF) energy harvesting is a promising technology for Internet-of-Things (IoT) devices to power sensors and prolong battery life. In this paper, we present a novel side-channel attack that leverages RF energy harvesting signals to ...

LoRa has emerged as a novel Internet of Things (IoT) communication paradigm, featuring with long-range and low-power transmission capabilities. With the widespread deployment of LoRa networks, the demand to perform Firmware Update Over-The-Air (FUOTA) ...

LoRa has emerged as one of the promising long-range and low-power wireless communication technologies for Internet of Things (IoT). With the massive deployment of LoRa networks, the ability to perform Firmware Update Over-The-Air (FUOTA) is becoming a ...

• An extended bond-based peridynamic (PD) model is used to investigate interfacial and subinterfacial fracture behaviors in bimaterial structures.

The interaction between crack propagation and interfaces is one of the critical problems in bimaterial systems. In this paper, interfacial and subinterfacial fracture behaviors are simulated to investigate this interaction. The ...

Wireless key generation is promising in establishing a pair of secret keys for ubiquitous Wi-Fi networks. However, existing Wi-Fi-based key generation systems are not always applicable in dynamic mobile wireless environments because they are completed ...

Pattern lock-based authentication has been widely adopted in modern smartphones. However, this scheme relies essentially on passwords, making it vulnerable to various side-channel attacks such as the smudge attack and the shoulder-surfing attack. In this ...

Recognizing indoor activities of an individual provides useful information in smart living, well-being monitoring, and fitness management. In this paper, we propose a simple and fast human activity recognition (HAR) system based on Radio Frequency ...

To address the issue of dynamic 3D circular features recognition in robot arm grasping, we propose a feature-based and incremental simultaneous points and circles structure from motion system. First, we represent the 3D target scene with sparse ...

This article focuses on the simultaneous wireless information and power transfer (SWIPT) systems, which provide both the power supply and the communications for Internet-of-Things (IoT) devices in the sixth-generation (6G) network. Due to the extremely ...

Marine hydraulic manipulator is limited by its size, weight and environment, so traditional hydraulic manipulator cannot be used for marine equipment. In this paper, large displacement pump is replaced by small displacement pump, accumulator is used as ...
