How safe is your face? The pros and cons of having facial recognition everywhere
Joanne Orlando, Western Sydney University
Walk into a shop, board a plane, log into your bank, or scroll through your social media feed, and chances are you might be asked to scan your face. Facial recognition and other kinds of face-based biometric technology are becoming an increasingly common form of identification.
The technology is promoted as quick, convenient and secure – but at the same time it has raised alarm over privacy violations. For instance, major retailers such as Kmart have been found to have broken the law by using the technology without customer consent.
So are we seeing a dangerous technological overreach or the future of security? And what does it mean for families, especially when even children are expected to prove their identity with nothing more than their face?
The two sides of facial recognition
Facial recognition tech is marketed as the height of seamless convenience.
Nowhere is this clearer than in the travel industry, where airlines such as Qantas tout facial recognition as the key to a smoother journey. Forget fumbling for passports and boarding passes – just scan your face and you’re away.
In contrast, when big retailers such as Kmart and Bunnings were found to be scanning customers’ faces without permission, regulators stepped in and the backlash was swift. Here, the same technology is not seen as a convenience but as a serious breach of trust.
Things get even murkier when it comes to children. Due to new government legislation, social media platforms may well introduce face-based age verification technology, framing it as a way to keep kids safe online.
At the same time, schools are trialling facial recognition for everything from classroom entry to paying in the cafeteria.
Yet concerns about data misuse remain. In one incident, Microsoft was accused of mishandling children’s biometric data.
For children, facial recognition is quietly becoming the default, despite very real risks.
A face is forever
Facial recognition technology works by mapping someone’s unique features and comparing them against a database of stored faces. Unlike passive CCTV cameras, it doesn’t just record, it actively identifies and categorises people.
This may feel similar to earlier identity technologies. Think of the check-in QR code systems that quickly sprung up at shops, cafes and airports during the COVID pandemic.
Facial recognition may be on a similar path of rapid adoption. However, there is a crucial difference: where a QR code can be removed or an account deleted, your face cannot.
Why these developments matter
Permanence is a big issue for facial recognition. Once your – or your child’s – facial scan is stored, it can stay in a database forever.
If the database is hacked, that identity is compromised. In a world where banks and tech platforms may increasingly rely on facial recognition for access, the stakes are very high.
What’s more, the technology is not foolproof. Mis-identifying people is a real problem.
Age-estimating systems are also often inaccurate. One 17-year-old might easily be classified as a child, while another passes as an adult. This may restrict their access to information or place them in the wrong digital space.
A lifetime of consequences
These risks aren’t just hypothetical. They already affect lives. Imagine being wrongly placed on a watchlist because of a facial recognition error, leading to delays and interrogations every time you travel.
Or consider how stolen facial data could be used for identity theft, with perpetrators gaining access to accounts and services.
In the future, your face could even influence insurance or loan approvals, with algorithms drawing conclusions about your health or reliability based on photo or video.
Facial recognition does have some clear benefits, such as helping law enforcement identify suspects quickly in crowded spaces and providing convenient access to secure areas.
But for children, the risks of misuse and error stretch across a lifetime.
So, good or bad?
As it stands, facial recognition would seem to carry more risks than rewards. In a world rife with scams and hacks, we can replace a stolen passport or drivers’ licence, but we can’t change our face.
The question we need to answer is where we draw the line between reckless implementation and mandatory use. Are we prepared to accept the consequences of the rapid adoption of this technology?
Security and convenience are important, but they are not the only values at stake. Until robust, enforceable rules around safety, privacy and fairness are firmly established, we should proceed with caution.
So next time you’re asked to scan your face, don’t just accept it blindly. Ask: why is this necessary? And do the benefits truly outweigh the risks – for me, and for everyone else involved?![]()

Tempted to turn on the aircon? Science says use fans until it’s 27°C
Many Australians struggle to keep themselves cool affordably and effectively, particularly with rising electricity prices. This is becoming a major health concern, especially for our most vulnerable people such as the elderly, pregnant women and people with cardiovascular diseases.
Air conditioning is often seen as the only solution to this problem. But relying too heavily on aircon has major downsides. These include hefty electricity bills, increased greenhouse gas emissions, strain on an already weak electricity grid, and dumping heat from buildings to the outside – further heating the outdoor air.
Our latest research, published in the Medical Journal of Australia, highlights a simple yet effective solution: a “fan-first” cooling approach.
The approach is simple: use electric fans as your first cooling strategy, and only turn on air conditioning when the indoor temperature exceeds 27°C.
Fan-First Cooling: The Smart Way to Beat Australia’s Heat Crisis (Federico Tartarini)
The solution: ‘fan-first’ cooling
Electric fans can make you feel more comfortable on a hot day simply by moving the air around you. This helps our body release heat in two ways: improving the transfer heat from your body into the air, and increasing the evaporation of sweat from your skin.
A gentle breeze can make you feel up to 4°C cooler, even when the weather is very hot and humid.
This allows you to increase the aircon set-point (the temperature at which cooling turns on) from 23-24°C to 27-28°C. This simple change can significantly reduce the amount of time your aircon is running, leading to substantial energy savings.
For example, in our previous research we showed raising the office air conditioning set-point from 24 to 26.5°C, with supplementary air movement from desk and ceiling fans, reduced energy consumption by 32%, without compromising thermal comfort.
Don’t fans still use electricity to run?
Yes fans still use electricity, but it’s as little as 3% of the electricity used to run air conditioning. That means you can run more than 30 fans with the same amount of energy it takes to run a single aircon unit.
A basic pedestal fan is cheap to buy (A$20 to $150), requires no installation and minimal maintenance, and can be easily moved around to keep you cool in any part of your house. Simply turn on the fan as soon as you start feeling slightly warm.
Fans cool you, whereas aircon cools the whole space, which is less efficient.
We also previously showed that using fans rather than airconditioning is a more effective emissions reduction strategy than switching from old-fashioned incandescent light bulbs to LED lighting.
The problem with over-reliance on aircon
Globally, the use of air conditioning is rapidly increasing. Aircon units sales have tripled since 1990 and are projected to triple again in 2050. It is becoming the go-to solution to heat management.
Aircon is effective but is expensive to buy, run and maintain.
A recent survey showed while most people have aircon, two thirds did not use it due to cost concerns.
Beyond the financial burden, the environmental impact of aircon is substantial. In Australia, electricity mainly comes from burning fossil fuels, creating greenhouse gas emissions. Even with the growth of renewable energy, the sheer demand for aircon cooling could strain the transition and the grid.
Furthermore, the refrigerants used in most aircon units are potent greenhouse gases. It will also take time to replace older and less efficient aircon units.
Aircon units also release heat into the outdoor environment, worsening the urban heat island effect – the phenomenon where cities are significantly warmer than surrounding rural areas.
Finally, over-reliance on aircon might reduce our ability to cope with heat. If we constantly keep our indoor temperatures very low, our bodies may not acclimatise to warmer summer conditions, making us more vulnerable during power outages.
Using fans safely and effectively
While fans offer numerous benefits, it’s important to use them correctly, especially in very hot indoor conditions.
There’s a common misconception that fans should be turned off above 35°C because they might blow hot air onto the skin. This ignores the crucial role fans play in evaporating sweat.
We have established safer and more accurate temperature thresholds for fan use by conducting laboratory studies. Just remember to check the temperature indoors, not outdoors.
Electric fans can be safely used in indoor temperatures up to:
- 39°C for young, healthy adults.
- 38°C for older adults.
- 37°C for older adults taking anticholinergic medications (which can impair sweating).
Above these indoor temperatures, fans could worsen heat strain by increasing cardiovascular strain and core body temperature. In such situations, alternative cooling strategies such as wetting the skin, moving to a cooler place, or turning the aircon on are essential.
Below these thresholds, we have proven, in laboratory studies, that there’s no reason to switch fans off, because they provide further thermal comfort and reduce heat stress.
Take action now
Based on our field and lab research, we suggest five simple steps to using fans for managing heat at home:
consider buying pedestal or ceiling fans
point the fan at your body and adjust the speed to your liking
wear light clothing and stay hydrated
if you have aircon, increase the set-point to 27-28°C
enjoy a reduced energy bill and increased comfort.
You may also want to ask your employer to install fans at your workplace and share this “fan-first” cooling strategy with family and friends.
Let’s work together towards a more sustainable future by reducing our reliance on energy-intensive air conditioning. This will lead to lower electricity costs, reduced greenhouse gas emissions, and increased resilience to heat.![]()
