In the digital age, the notion of complete personal privacy is becoming obsolete. We are always leaving digital traces wherever we go, making it virtually impossible to be truly offline. This constant stream of data is fueled by an accelerating global trend where both governments and corporations are racing to collect vast amounts of identifying information, transforming the way cities function and raising profound questions about human rights.
The Science of Uniqueness: From Fingerprints to Veins
The search for unique identifiers has a long history, starting with fingerprints, which were even used in early Chinese pottery by the potter to mark their work in the wet clay. Today, while DNA remains the gold standard for identification, even its presence at a crime scene doesn't tell the whole story, as it's often difficult to establish how the DNA got there.
The next frontier in biometrics is the hand. New research suggests that unique features, such as the skin creases over our knuckles (which differ in every finger and even between identical twins) and the patterns created when infrared light interacts with deoxygenated blood in our veins, could be the "holy grail" of unique personal identifiers. The ability to simply place a hand or finger on a device could unlock limitless possibilities, providing access to a person's exact health statistics, genetic risks, and more.
The Peril of the Data Economy
While collecting vast amounts of biometrics can create incredibly positive situations—such as a functioning government efficiently allocating resources based on data—it is also fraught with peril. The famous quote, "if you haven't done anything wrong, why would you be scared of ghosts," is often used to justify mass surveillance. However, this approach fails to value personal privacy.
The Illusion of Anonymity: Anonymity is fragile. When Netflix released what it thought were anonymized movie-watching records to improve recommendation algorithms, researchers were quickly able to cross-reference the data with other online rating services. Once an individual was identified, their seemingly anonymous data could be used to deduce highly personal details.
The Social Credit Score: The data collection trend could lead to systems like a social credit score, where local government, schools, and workplaces feed data into a single score that evaluates trustworthiness. A low score could potentially lead to restrictions on the ability to borrow money or even travel on public transport.
The Cautionary Lesson: In places like Shenzhen, CCTV cameras use facial recognition to catch jaywalkers, identify the citizen, and display their name and image on a large billboard for public shaming. What happens in countries where regulation is lacking serves as a serious cautionary lesson for the rest of the world: without proper regulation, the unchecked gathering of data is a real danger to human rights.
The Regulatory Race and the Right to Privacy
The digital world is accelerating so fast that regulation is constantly chasing where we are with the current technology.
Companies often provide pages of terms and conditions, offering transparency, but few people have the time or knowledge to read them, meaning the transparency is merely apparent, not actual. The collection of biometric data is particularly personal, and once it is given away, it is incredibly hard, if not impossible, to retrieve.
The core philosophical question boils down to privacy: if the government promised to put a camera in every bedroom and only turn it on when there was suspicion, most people would object, arguing that while they have nothing to hide, the bedroom is private. In reality, the vast amounts of data gathered about us today can give information as detailed as if there were a camera in our private spaces. The key question for the accelerating digital world is how to ensure that these incredibly useful, large-scale databases are used correctly and do not infringe on human rights.
