Researchers at the University of California have developed a technique called Mic-E-Mouse, which can use a regular computer mouse's sensor as a covert microphone. The research found that under certain conditions, conversations and numerical information can be recorded from the mouse. This study warns of a privacy threat from computer peripheral devices.
Mic-E-Mouse: Researchers at the University of California have introduced a new method in which a regular computer mouse's sensor can be used as a sensitive microphone. This technique can record conversations and numerical information through vibrations generated by the mouse under specific circumstances. The study also noted that an attack is only possible if the system is already infected with malware and the environment is quiet. Researchers state that this discovery emphasizes the importance of security and privacy for computer peripheral devices.
Mic-E-Mouse Technology
Researchers at the University of California have developed a new technique, which they have named Mic-E-Mouse. This technique utilizes the sensitive sensor of a common computer mouse as a covert microphone. According to the research, the sensor can also pick up acoustic vibrations generated by the human voice, which could allow some conversations or digits to be recorded if the system is compromised.
The Mic-E-Mouse technique uses a Wiener filter and an AI model to clean the data, allowing for the identification of words or digits. The research found success in capturing certain speech frequencies with approximately 61% accuracy, with a particular focus on numerical information such as numbers and credit card details.
How It Works and Under What Conditions an Attack is Possible
Mic-E-Mouse can only function if the mouse is on a flat and clean surface, the environment is quiet, and the system is already infected with malware. A mouse mat or desk cover weakens the signal, and identifying conversations becomes difficult in noisy environments. The research also clarified that general word recognition is challenging, so the risk is primarily limited to numerical data.
Researchers explain that the mouse's sensors can pick up even small vibrations, and it is possible to convert these into digital signals using technical methods and identify them through an AI model. This process could put confidential information at risk, but it is only effective under specific circumstances.
Why This Study Is Important
The Mic-E-Mouse research conveys the message that peripheral devices of computers and laptops can also pose risks regarding privacy and security. Even though implementing this technique is not easy, it serves as a warning that hardware sensors and their data should not be overlooked.
