Smart phones are very popular and used by over seven billion people. Each day seven million dollars worth of cell phones is lost or stolen. Without an authentication device, personal data stored on the device can be used for identity theft or the phone can be used for unauthorized purposes. Most authentication systems authenticate a user only once when...

Hypertext Transfer Protocol (HTTP) transfers information across the World Wide Web by routing packets of data from the web’s most available servers to a client, whose browser then builds a webpage (or streams media) from those packets. MPEG’s Dynamic Adaptive Streaming over HTTP (DASH), Apple’s HTTP Live Streaming, Microsoft Smooth...

The most advanced Body Sensor Networks (BSNs) consist of wireless electronic sensors that are worn by patients and communicate wirelessly with a smartphone or computer. These sensors can be invasive or they must be put on every time a patient is monitored, which can be especially inconvenient for non-human patients. Currently, no non-invasive method...

5G wireless systems are designed to meet the increasing demand for high data rates but face challenges like signal obstruction, poor penetration, high propagation loss, and inadequate scattering. Active relays have emerged as a solution to these issues by re-routing signals to avoid obstructions, ensuring uninterrupted 5G service. However, in dense...

Networks like those of healthcare infrastructure have been a primary target of cyberattacks for over a decade. From just a single cyberattack, a healthcare facility would expect to see millions of dollars in losses from legal fines, business interruption, and malpractice lawsuits. As more medical devices become interconnected, more cyber vulnerabilities...

Image processing systems gather and convey information using image sensors enabling a variety of IoT and mobile applications. IoT systems utilize image sensors to perform a multitude of various tasks that are important in all aspects of life such as detecting wildfires in forests, lifesaving medical imaging and reality headsets that use body tracking....

Cyber risk has emerged as a significant threat to businesses that have increasingly relied on new and existing information technologies. Across various businesses in different industries and sectors, a distinct pattern of IT network architectures, such as the client-server network architecture, may expose those businesses, which share it, to similar...

Detecting angle of arrival (AoA) of electromagnetic (EM) signals is a priority for many civil and military applications including navigation, surveillance, and communication systems. The antenna structures typically used for this purpose are required to conform to nearly arbitrary surfaces including robots, cars, aerial vehicles, and missiles. As...

Many navigation systems rely on detecting the angle of arrival (AoA) of waves to determine desired coordinates. For example, a variety of radar systems deploy AoA detection to deliver desired information about the surrounding area or target of interest. Modern radio environments rely on adaptive beamforming techniques to direct electromagnetic waves...

The ubiquitous and heterogeneous deployment of internet of things (IoT) devices in smart homes has created new opportunities to extract knowledge, awareness, and intelligence via monitoring and understanding the devices’ interactions with their environments and users. Meaningful information from network traffic of IoT devices in smart homes can...
