Furthermore, by arranging the transducers in a ring layout, our wearable jams in multiple directions and protects the privacy of its user’s voice, anywhere and anytime, without requiring its user to manually point the jammer to the eavesdropping microphones. Speech recognition results when the microphone is covered up with various objects. By turning an ultrasonic jammer into a bracelet, our device leverages natural hand gestures that occur while speaking, gesturing or moving around to blur out the aforementioned blind spots. We confirmed that an ultrasonic microphone jammer is superior to state-of-the-art and commercial stationary jammers by conducting a series of technical evaluations and a user study. It may look clunky, but this wearable microphone jammer will disable hidden microphones in your immediate surroundings. Our device is based on a recent exploit that leverages the fact that when exposed to ultrasonic noise, commodity microphones will leak the noise into the audible range. To tackle these shortcomings, we engineered a wearable jam-mer that is worn as a bracelet, which is depicted in Figure 1. This bracelet looking device may look clunky but its powerful enough to render microphones useless. Congrats to Jenna, Shiliang and Xinyi on their CHI paper on gender bias detection! The device is based on a recent exploit that leverages the fact that when exposed to ultrasonic noise, commodity microphones will leak the noise into the audible range. (a) We engineered a wearable ultrasound jammer that can prevent surrounding microphones from eavesdropping on a conversation. https://doi.org/10.1145/3313831.3376304. 2020. The wearable jammer has a word error rate (WER) of above 87% regardless of the position of the microphone (blue trace). Increasingly popular digital assistants and home smart devices have raised privacy concerns over their “always on” microphones and the potential for unintentional recordings. wearable microphone jamming We engineered a wearable microphone jammer that is capable of disabling microphones in its user’s surroundings, including hidden microphones.

By turning an ultrasonic jammer into a bracelet, our device Congrats to Yuxin, Huiying and Shan-Yuan on their CHI paper on Wearable Microphone Jammers! The wearable jammer does its job against nearby and hidden microphones, thanks to researchers at the school's SAND Lab and the Human Computer Integration Lab. While these ultrasonic signals are imperceptible to human ears, they leak into the audible spectrum after being captured by the microphones, producing a jamming signal inside the microphone circuit that jams (disrupts) voice recordings. However, (c) is the transcript of what a state-of-the-art speech recognizer makes out of the jammed conversation. Speech recognition with no jamming (A). A University of Chicago team has come up with a wearable microphone jammer in the form of a bracelet that can disable microphones in a person's surroundings. transducer jammer are blind spots. Designer, developer and manufacturer of speaker systems. Microphone Furry Windscreen Windjammer for MV88 - Customized Pop Filter Deadcat Windshield Wind Jammer for Shure MV88 iOS Digital Stereo Condenser Mic by YOUSHARES 4.0 out of 5 stars 70 $11.49 $ 11 . The bracelet randomly emits ultrasonic noise to jam microphones in speakers, smartwatches and smartphones. The wearable jammer has a word error rate (WER) of above 87% regardless of the position of the microphone (blue trace). •When a microphone is outside the effective angle of a current jammers, the word error rate (WER) is only about 26%. Structure of this repo Our simulations depict how different transducer layouts radiate around the simulated device. It was intentional to ensure omnidirectional jamming. Our device is based on a recent exploit that leverages the fact that when exposed to ultrasonic noise, commodity microphones will leak the noise into the audible range. ( Find code here ), From left to right: Pedro Lopes, Huiying Li, Yuxin Chen and Shan-Yuan Teng. Recently, researchers have shown that ultrasonic transducers can prevent commodity microphones from recording human speech.

Not shown: Steven Nagels, Zhijing Li, Ben Zhao and Heather Zheng. Their device is based on a recent exploit that leverages the fact that when exposed to ultrasonic noise, commodity microphones will leak the noise into the audible range. Our device is based on a recent exploit that leverages the fact that when exposed to ultrasonic noise, commodity microphones will leak the noise into the audible range. Therefore, it is critical to build tools that protect users against the potential compromise or misuse of microphones in the age of voice-based smart devices. By turning an ultrasonic jammer into a bracelet, our device leverages natural hand gestures that occur while speaking, gesturing or moving around to blur out the aforementioned blind spots. The bracelet design is by no accident, btw. >To tackle these shortcomings, we engineered a wearable jammer that is worn as a bracelet, which is depicted in Figure 1. The leakage is caused by an inherent, nonlinear property of microphone’s hardware. Wearable Microphone Jammer. Chicago, IL 60637 4.0 out of 5 stars 14. •Wearable design is portable, discreet, and harnesses natural gestures during speech to reduce blind spots, •Curved transducer layout further decreases blind spots, •Proximity to the user prevents the separation of the speaker’s voice and the jammer. We demonstrate that these movements can blur jamming blind spots and increase jamming coverage. Moreover, our device exploits a synergy between ultrasonic jamming and the naturally occurring movements that users induce on their wearable devices (e.g., bracelets) as they gesture or walk. This is beneficial in that it allows our jammer to protect against microphones hidden out of sight. Wearable Microphone Jamming Repository for our paper Wearable Microphone Jamming. 5807 S. Woodlawn Ave. Yuxin Chen, Huiying Li, Shan-Yuan Teng, Steven Nagels, Zhijing Li, Pedro Lopes, Ben Y. Zhao, and Haitao Zheng. If a microphone is placed in any of these locations it will not be jammed, rendering the whole jammer obsolete. We found that the WER for planar and i4 dropped drastically after 90 degree, while our wearable maintained a constant jamming effect >87%.
