Scientists demonstrate use of sensors to eavesdrop on phone calls remotely
WASHINGTON: Researchers have demonstrated a method to detect the vibrations of a mobile phone’s earpiece and decipher what the person on the other side of the call was saying with up to 83 per cent accuracy.
The team at Pennsylvania State University used an off-the-shelf automotive radar sensor and a novel processing approach to reveal this significant security concern.
“As technology becomes more reliable and robust over time, the misuse of such sensing technologies by adversaries becomes probable,” said Suryoday Basak, doctoral candidate at Penn State.
“Our demonstration of this kind of exploitation contributes to the pool of scientific literature that broadly says, ‘Hey! Automotive radars can be used to eavesdrop audio. We need to do something about this’,” Basak said.
The radar operates in the millimeter-wave (mmWave) spectrum, specifically in the bands of 60 to 64 gigahertz and 77 to 81 gigahertz, which inspired the researchers to name their approach “mmSpy.”
This is a subset of the radio spectrum used for 5G, the fifth-generation standard for communication systems across the globe.
In the mmSpy demonstration, described in 2022 IEEE Symposium on Security and Privacy (SP), the researchers simulated people speaking through the earpiece of a smartphone.
The phone’s earpiece vibrates from the speech, and that vibration permeates across the body of the phone.
“We use the radar to sense this vibration and reconstruct what was said by the person on the other side of the line,” said Basak.
The researchers, including Mahanth Gowda, an assistant professor at Penn State, noted that their approach works even when the audio is completely inaudible to both humans and microphones nearby.
“This isn’t the first time similar vulnerabilities or attack modalities have been found, but this particular aspect — detecting and reconstructing speech from the other side of a smartphone line — was not yet explored, Basak said.
The radar sensor data is pre-processed via MATLAB and Python modules, which are computing platform-language interfaces used to remove hardware-related and artefact noise from the data.
The researchers then feed that to machine learning modules trained to classify speech and reconstruct audio.
When the radar senses vibrations from a foot away, the processed speech is 83 per cent accuracy. That drops the farther the radar moves from the phone, down to 43 per cent accurate at six feet, they said.
Once the speech is reconstructed, the researchers can then filter, enhance or classify key words as needed, Basak said.
The team is continuing to refine their approach to better understand not only how to protect against this security vulnerability, but also how to exploit it for good.
“The methodology that we developed can also be used for sensing vibrations in industrial machinery, smart home systems and building-monitoring systems,” Basak said.
According to the researchers, there are similar home maintenance or even health monitoring systems that could benefit from such sensitive tracking.
“Imagine a radar that could track a user and call for help if some health parameter changes in a dangerous way,” Basak said.
“With the right set of target actions, radars in smart homes and industry can enable a faster turnaround when problems and issues are detected, he added.

NEW DELHI: Yotta Data Services, an end-to-end Digital Transformation service provider, has announced that its state-of-the-art data centre facility, “Yotta G1”, located in GIFT city, Gandhinagar is ready for service (RFS).
The opening of this data center marks the debut of Yotta in Gujarat and progresses the company’s mission to provide digital services in India’s high-growth markets.
G1 is Yotta’s fifth data center facility in the country. It joins four large operational data centers, two of which, at Navi Mumbai and Greater Noida are part of hyperscale campuses. Yotta G1 is uniquely located inside the International Financial Services Center (IFSC) zone of Gandhinagar’s Gujarat International Finance Tec-City (GIFT city).
G1 represents an investment of more than INR 500 cr. over five years across critical non-IT and IT / Cloud / AI compute infrastructure. The data center has a capacity of over 350 high-density racks and 2 MW power (which can be scaled further as per demand). The facility is designed to meet the most demanding digital needs of its customers, who may be located within GIFT City or anywhere in the world, by seamlessly delivering fault-tolerant facility infrastructure, high-performance Cloud compute and storage infrastructure, advanced physical and cyber security, unmatched connectivity, and steadfast sustainability.
For large global enterprises operating in the GIFT City IFSC zone, the G1 data center functions as a potential data embassy, whereby their data stored is subject to the laws and regulations of their home country, thus allowing them to maintain sovereignty over their data, even when stored in India. By storing data in a physically different location, global enterprises can ensure continuity of operations in case of major disruptions within their borders. The data center’s location also ensures compliance with the IFSC regulations, providing businesses in the zone with distinct advantages like free foreign exchange convertibility, a liberalised regulatory environment, and business-friendly policies. It also helps enterprises adhere to IFSC’s compliance requirements, including being mandated to host their data within the IFSC zone.
Commenting on the announcement, Darshan Hiranandani, Co-founder and Chairman, Yotta Data Services, said, “The state of Gujarat, with GIFT City, has been at the forefront of providing a viable and sustainable platform for global businesses to set up base in India. The setting up of the IFSC zone is a further testament to their vision for financial services companies. We are proud to support this vision of the Gujarat government with a state-of-the-art data center within the IFSC zone, providing the latest and best in cutting-edge technologies to help businesses set up and scale their businesses while also adhering to all regulatory requirements.”
Adding to this, Sunil Gupta, Co-Founder, MD & CEO, Yotta Data Services, said, “Yotta’s G1 marks a pivotal milestone in delivering high-end data center, Cloud, AI compute, storage, connectivity and cybersecurity services to enterprises both on a global and local scale in the Gujarat region. Besides serving the domestic enterprises within and outside GIFT City, our data center shall serve as a potential data embassy for global enterprises, enabling them to adhere to their respective country’s laws while offering a dependable and secure locale for offshore data storage.”
G1 data centre stands distinct in GIFT city for being a data center offering more than just colocation services. True to Yotta’s stature as the end-to-end digital transformation partner of choice for enterprises, G1 brings forth a suite of key features, ranging from advanced data security and customised business solutions to an indigenous hyperscale cloud offering, AI-GPU compute offering, state-of-the-art infrastructure, cybersecurity expertise, seamless integration with managed IT services, 24/7 customer support, cost optimisation, and an overall competitive edge.
