Safeguarding Neural Privacy: The Need for Expanded Legal Protections of Brain Data

Abstract

Emerging technologies like brain-scanning headbands, meditative earphones, and neural implants enable unprecedented access to individuals' private mental states and neural activity. Companies now have the capability to detect, record, and analyze brain data reflecting users' emotions, imagination, decision-making, and even subconscious thoughts. However, glaring regulatory gaps surround what firms can legally do with neural data, including sharing or selling it without users' knowledge or permission. This paper spotlights the privacy risks tied to uncontrolled harvesting of individuals' brainwave information by corporate interests. It highlights recent evidence that some technology companies already admit to sharing customers' neural data with third parties and using it for targeted advertising purposes. At present, few laws specifically protect neural privacy or guarantee individuals' rights to control access to their own brain data. Colorado has emerged as a pioneer in this uncharted legislative domain through its recent passage of a first-of-its-kind state law safeguarding neural data as private property. The law mandates that companies obtain explicit user consent before collecting brainwave information via headsets, earbuds, implants, or related devices. It also grants Colorado residents new abilities to access their neural data from tech firms, request its deletion, and forbid its sale for marketing uses. Policy experts describe Colorado's protections as a critical turning point likely to catalyze further neural privacy laws nationwide. However, comparable safeguards remain rare globally outside parts of the US and Western Europe. This troubling lack of neural data oversight threatens universal rights to mental privacy regardless of nationality or geography. Advocates urge the rapid international adoption of clear policy frameworks to regulate corporate mining of human brain data before prevailing practices become entrenched. The paper concludes by underscoring Colorado's law as a clarion call to galvanize citizens, scientists, ethicists, and political leaders worldwide to act in defense of one of humanity's most intimate and vulnerable spheres of individual liberty – the privacy of our own unspoken thoughts.
