Amazon is launching a new product line to enable users to control the storage of voice recordings from Alexa devices, while privacy-related issues are also of concern. According to the international team of researchers, voice assistants such as Apple’s Siri, Amazon’s Alexa, and Google Assistant can be invaded by launching a laser on the device’s microphone. Experts at Tokyo University of Electro-Communications and the University of Michigan issued a statement saying that the hacker, known as the “light command”, “allows an attacker to inject inaudibly and commands into the voice assistant.” Researchers say that by aiming at a Micro Electro Mechanical System (MEMS) microphone with a laser, they can make the microphone respond to light, just like a sound. They wrote in the research paper: “With this effect, an individual can inject sound into the microphone by simply changing the amplitude of the laser.”
An Amazon speaker told Fox News via email: “Customer trust is a priority, and take customer trust in our products seriously. We are examining this research and continue to rivet with the author to learn more about them.” Despite this, Apple, Tesla, and Ford still have not responded to criticism of the matter. For years, privacy issues around voice assistants have been plaguing people. For example, Amazon’s Echo device is regularly checked to check user data. Due to concerns regarding privacy, Amazon recently announced a new product line that gives Alexa users more control over stored voice recordings.
Alexa is at the forefront of Amazon’s efforts to take advantage of the so-called Internet of Things, which is designed to connect a variety of consumer electronics. To keep data locked, Amazon customers can set up voice PINs for shopping, opening smart home requests, and accessing sensitive information such as banks. It should be noted that hacking a voice assistant with a laser requires specialized knowledge and specialized equipment, as well as a clear view of the target device.
