Emerging brain-computer interface technology introduces vulnerabilities, including neural data interception, signal manipulation, and neuroprivacy concerns.
Neuroscience suggests that while the idea of "hacking" the human brain sounds like sci-fi, emerging brain-computer interface (BCI) technology introduces real vulnerabilities.
According to a report by University of Maryland Global Campus, BCIs, whether invasive implants or noninvasive wearable sensors, translate neural signals into digital commands, enabling applications from prosthetic control to gaming.
According to a study by Cornell University, security concerns are multifaceted. First, hackers could intercept neural data streams, essentially reading thoughts transmitted from brain to device. Researchers have demonstrated "backdoor" attacks on EEG-based BCIs: tiny perturbations injected into brainwave-analysis algorithms can alter outcomes, from benign coaching tools to critical medical diagnostics.
Second, the integrity of neural signals can be compromised, manipulated, or spoofed, potentially influencing emotions, decisions, or behaviour. In extreme cases, implanted deep-brain stimulators (used for Parkinson's) can be hacked to alter brain function directly.
