The Internet of Bodies: Opportunities, Risks, and Governance (RAND, 2020) by Mary Lee, Benjamin Boudreaux, Ritika Chaturvedi, Sasha Romanosky, Bryce Downing comments
A wide variety of internet-connected “smart” devices now promise consumers and businesses improved performance, convenience, efficiency, and fun. Within this broader Internet of Things (IoT) lies a growing industry of devices that monitor the human body, collect health and other personal information, and transmit that data over the internet. We refer to these emerging technologies and the data they collect as the Internet of Bodies (IoB) (see, for example, Neal, 2014; Lee, 2018), a term first applied to law and policy in 2016 by law and engineering professor Andrea M. Matwyshyn (Atlantic Council, 2017; Matwyshyn, 2016; Matwyshyn, 2018; Matawyshyn, 2019).
IoB devices come in many forms. Some are already in wide use, such as wristwatch fitness monitors or pacemakers that transmit data about a patient’s heart directly to a cardiologist. Other products that are under development or newly on the market may be less familiar, such as ingestible products that collect and send information on a person’s gut, microchip implants, brain stimulation devices, and internet-connected toilets.
These devices have intimate access to the body and collect vast quantities of personal biometric data. IoB device makers promise to deliver substantial health and other benefits but also pose serious risks, including risks of hacking, privacy infringements, or malfunction. Some devices, such as a reliable artificial pancreas for diabetics, could revolutionize the treatment of disease, while others could merely inflate health-care costs with little positive effect on outcomes. Access to huge torrents of live-streaming biometric data might trigger breakthroughs in medical knowledge or behavioral understanding. It might increase health outcome disparities, where only people with financial means have access to any of these benefits. Or it might enable a surveillance state of unprecedented intrusion and consequence. There is no universally accepted definition of the IoB. For the purposes of this report, we refer to the IoB, or the IoB ecosystem, as IoB devices (defined next, with further explanation in the passages that follow) together with the software they contain and the data they collect.
An IoB device is defined as a device that
• contains software or computing capabilities
• can communicate with an internet-connected device or network and satisfies one or both of the following:
• collects person-generated health or biometric data
• can alter the human body’s function.
The software or computing capabilities in an IoB device may be as simple as a few lines of code used to configure a radio frequency identification (RFID) microchip implant, or as complex as a computer that processes artificial intelligence (AI) and machine learning algorithms. A connection to the internet through cellular or Wi-Fi networks is required but need not be a direct connection. For example, a device may be connected via Bluetooth to a smartphone or USB device that communicates with an internet-connected computer. Person-generated health data (PGHD) refers to health, clinical, or wellness data collected by technologies to be recorded or analyzed by the user or another person. Biometric or behavioral data refers to measurements of unique physical or behavioral properties about a person. Finally, an alteration to the body’s function refers to an augmentation or modification of how the user’s body performs, such as a change in cognitive enhancement and memory improvement provided by a brain-computer interface, or the ability to record whatever the user sees through an intraocular lens with a camera.
IoB devices generally, but not always, require a physical connection to the body (e.g., they are worn, ingested, implanted, or otherwise attached to or embedded in the body, temporarily or permanently). Many IoB devices are medical devices regulated by the U.S. Food and Drug Administration (FDA). Figure 1 depicts examples of technologies in the IoB ecosystem that are either already available on the U.S. market or are under development.
Devices that are not connected to the internet, such as ordinary heart monitors or medical ID brace- lets, are not included in the definition of IoB. Nor are implanted magnets (a niche consumer product used by those in the so-called bodyhacker community, described in the next section) that are not connected to smartphone applications (apps), because although they change the body’s functionality by allowing the user to sense electromagnetic vibrations, the devices do not contain software. Trends in IoB technologies and additional examples are further discussed in the next section.
Some IoB devices may fall in and out of our definition at different times. For example, a Wi-Fi-connected smartphone on its own would not be part of the IoB; however, once a health app is installed that requires connection to the body to track user information, such as heart rate or number of steps taken, the phone would be considered IoB. Our definition is meant to capture rapidly evolving technologies that have the potential to bring about the various risks and benefits that are discussed in this report. We focused on analyzing existing and emerging IoB technologies that appear to have the potential to improve health and medical outcomes, efficiency, and human function or performance, but that could also endanger users’ legal, ethical, and privacy rights or present personal or national security risks.
For this research, we conducted an extensive literature review and interviewed security experts, technology developers, and IoB advocates to under- stand anticipated risks and benefits. We had valuable discussions with experts at BDYHAX 2019, an annual convention for bodyhackers, in February 2019, and DEFCON 27, one of the world’s largest hacker conferences, in August 2019. In this report, we discuss trends in the technology landscape and outline the benefits and risks to the user and other stakeholders. We present the current state of gover- nance that applies to IoB devices and the data they collect and conclude by offering recommendations for improved regulation to best balance those risks and rewards.
