MobRFFI: Non-cooperative Device Re-identification for Mobility Intelligence

arXiv.org Artificial Intelligence

I-SENSE (The Institute for Sensing And Embedded Network Systems Engineering) Florida Atlantic University Boca Raton, FL, USA { smazokha2016, fbao2015, gsklivanitis, jhallstrom } @fau.edu Abstract --WiFi-based mobility monitoring in urban environments can provide valuable insights into pedestrian and vehicle movements. However, MAC address randomization introduces a significant obstacle in accurately estimating congestion levels and path trajectories. T o this end, we consider radio frequency fingerprinting and re-identification for attributing WiFi traffic to emitting devices without the use of MAC addresses. We present MobRFFI, an AI-based device fingerprinting and re-identification framework for WiFi networks that leverages an encoder deep learning model to extract unique features based on WiFi chipset hardware impairments. It is entirely independent of frame type. When evaluated on the WiFi fingerprinting dataset WiSig, our approach achieves 94% and 100% device accuracy in multi-day and single-day re-identification scenarios, respectively. We also collect a novel dataset, MobRFFI, for granular multi-receiver WiFi device fingerprinting evaluation. Using the dataset, we demonstrate that the combination of fingerprints from multiple receivers boosts re-identification performance from 81% to 100% on a single-day scenario and from 41% to 100% on a multi-day scenario. Mobility monitoring in urban environments can provide valuable insights into pedestrian and vehicle movements. However, public disapproval of computer vision approaches due to privacy concerns opens opportunities for research into alternative, privacy-centric solutions, such as WiFi sensing. Modern mobile devices ubiquitously support the 802.11 standard and regularly emit WiFi probe requests for network discovery.


Boca Bash partier's parents issue apology after son caught dumping bins of trash into ocean

FOX News

A YouTube based in Florida's iconic Haulover Inlet, set between Bal Harbour and Sunny Isles in Miami-Dade County, posted this video during a boozing weekend. The family of one of two teen boys facing felonies for dumping drums of trash into the Atlantic Ocean at Florida's annual Boca Bash issued an apology after their son turned himself in to the Florida Fish and Wildlife Conservation Commission (FWC). Now-viral drone footage shows the teens hefting two trash bins filled with bottles and other plastics over the railing of their fishing vessel as they speed away from the boozy water gathering on April 28. As the boat of partiers zoomed away into the choppy waters of the Boca Raton inlet, the video pans out to the spread of debris left floating in their wake. Footage from the front of the boat shows the teens waving and laughing.


Artificial intelligence helping detect early signs of breast cancer in some US hospitals

FOX News

Doctors believe Artificial Intelligence is now saving lives after a major advancement in breast cancer screenings. In some cases, AI is detecting early signs of the disease years before doctors would find the cancer on a traditional scan. Boca Raton, FL – Some doctors believe artificial intelligence is saving lives after a major advancement in breast cancer screenings. In some cases, AI is detecting early signs of the disease years before the tumor would be visible on a traditional scan. The Christine E. Lynn Women's Health and Wellness Institute at the Boca Raton Regional Hospital found a 23% increase in cancer cases since implementing AI during breast cancer screenings.


Guident is making autonomous vehicles safer, with a human touch - Refresh Miami

#artificialintelligence

Does your car drive itself? And sooner than you expect. Analysts predict the global self-driving car market to grow from 20.3 million units in 2021 to 62.4 million units by 2030, at a CAGR of 13.3%. Of course, that is still a small portion of the almost 1.5 billion cars in the world – 300 million of which are in the US. Still, these prospects excite Harald Braun, executive chairman of Guident, a Boca Raton-based startup that is developing software to power the next generation of autonomous vehicles. "I focus on making autonomous vehicles connected," Braun told Refresh Miami.

FAU Unveils Center for Connected Autonomy and Artificial Intelligence

#artificialintelligence

The Center for Connected Autonomy and Artificial Intelligence is housed in the state-of-the-art Engineering East building on the Boca Raton campus. Artificial intelligence technologies are quickly evolving and changing every aspect of industry in the United States and globally. Artificial intelligence enables autonomy by robotic mobility and control learned through examples and computational decision-making and estimation from data using past training data experience. It has the ability to process large amounts of data much faster and make predictions more accurately than humanly possible. To rapidly advance the field of artificial intelligence and autonomy, Florida Atlantic University's College of Engineering and Computer Science recently unveiled its "Center for Connected Autonomy and Artificial Intelligence" (CCA-AI), a cutting-edge center designed to accelerate the development of innovative artificial intelligence and autonomy solutions.

The 1970s Xerox Conference That Predicted the Future of Work

WIRED

In November 1977, some 300 executives and their wives flew in from all over the world on first-class tickets to spend four days in the sun at the Xerox World Conference. Between meetings for the men and fashion shows for the wives, the visitors slept in luxury rooms at the Boca Raton Hotel and Club and attended cocktail parties and a keynote by Henry Kissinger. Now, on the last morning of the last day, they had assembled for the highlight of the conference: Futures Day, an invitation-only demonstration of the Alto personal computer system developed at Xerox PARC, the company's research center in Palo Alto.
