Forged digital images or video can threaten reputations or impede criminal justice, due to falsified evidence. Over the past decade, researchers have developed a new class of security techniques known as 'multimedia forensics' to determine the origin and authenticity of multimedia information, such as potentially falsified images or videos. However, the proliferation of smartphones and the rise of social media have led to an overwhelming increase in the volume of multimedia information that must be forensically authenticated.

With the growing use of implantable and wearable medical devices, information security for such devices has become a major concern. Prior work in this area mostly focuses on attacks on the wireless communication channel among these devices and health data stored in online databases. The proposed work is a departure from this line of research and is motivated by acoustic and electromagnetic physiological information leakage from the medical devices. This type of information leakage can also directly occur from the human body, thus raising privacy concerns.
