Security and Privacy concerns in Voice Assistants Devices

Abstract

Voice assistant devices are the new generation devices which provides voice interfaces to interact. They are backed with powerful technologies and service providers. These devices perform various tasks by just providing voice commands. Although it has many uses but there is a risk associated with it. The main concern with these devices is continuous listening. In order to provide a real time response, these devices keep their microphone on. Which compromises user’s privacy as well as security. Numerous approaches have been carried out but still it’s an issue which requires strong attention. In this work, we are focusing on how to avoid the continuous listening and how to protect user’s privacy. Adversaries target the Voice assistant devices when user is not aware or user is not around. They can collect the data, control the connected IoT devices, or can waste user’s resources. We present an approach that provides solution to all these problems. We propose a Jammer mechanism which can be controlled by the mobile phone. It jams the microphone whenever the user wants and protect user’s privacy as well as keep safe from unknown attacks. The jammer gets one more layer of protection by Bluetooth module, which does not let an attacker connect to the device.
