However, this progress must be accompanied by responsible use, stringent regulations, and ongoing discussions about its ethical boundaries.
In this rapidly evolving landscape, it is essential for individuals, organizations, and policymakers to weigh the pros and cons carefully, always striving to strike a balance that safeguards both security and individual rights.
The path forward for biometric surveillance will be shaped by our collective commitment to responsible innovation and ethical practices in this era of heightened digital scrutiny.
