Some wear flimsy medical masks and swimming goggles, others heavy-duty respirators and protective glasses. All are covering their faces to protect themselves not only from police tear gas — but also to obscure their identities.
But Hong Kong’s protesters aren’t the only ones worried about protecting their identities.
Activists, designers and artists around the world are inventing creative ways to avoid detection.
As state surveillance becomes more advanced — and widely used — wearable technology has been proposed as a way to thwart monitoring systems.

Fighting technology with technology
In some countries, there were internet black outs. In others, widespread censorship.

The kit also features a wearable device that alerts fellow demonstrators to the presence of police, and a stencil that creates graffiti “tags” — readable only by an app — to inform protesters when an area is under surveillance.
But the kits are not for sale. Instead, Oliveira and Chen hoped to start a dialogue about what they see as an increasing power imbalance between authorities and demonstrators.
“We didn’t feel that these should be offered to protesters as a solution. We just thought it was important to research and have a conversation about the hyper-militarization of police and all this technology being used against protesters,” Oliveira said in a phone interview.

Advancements in facial recognition technology is of particular concern to demonstrators and privacy campaigners.
The technology, much of which is still in development, works by capturing images of people’s faces and matching biometric information — such as the distance between facial features — with existing photo ID databases.
He also recommends make-up be applied asymmetrically, in order to throw off facial-recognition algorithms.

But these unusual tactics can create problems of their own. As artist Leo Selvaggio points out: “Walking out with this make-up on your face … actually makes you conspicuous.”
Selvaggio believes that people have also been “weaponized” into being part of surveillance, meaning that someone would likely report anything out of the ordinary — like unusual make-up or a blob-like mask — to the authorities.
“(Anti-surveillance projects) don’t really take into account the human aspect of surveillance,” he added in a phone interview.
The artist has proposed another solution: prosthetic masks of his own face. Like Blas’ “collective” masks, they hide the wearer’s true identity. But unlike Blas’ disguises, they would be analyzed as a human face by surveillance systems, fooling authorities into thinking that one person is in multiple places at the same time.

Simple solutions in Hong Kong
On the streets of Hong Kong, protesters have opted for readily available solutions.
“It’s often the simple solution — the quick solution — that’s the elegant and effective one,” said Grindon.
When it comes to avoiding detection, many opt for a medical or gas mask paired with goggles to obscure their identities.
“We need to hide ourselves so if we get caught on camera, we’re safe,” said a 22-year-old volunteer first aider, who spoke on condition of anonymity, for security reasons.
She is concerned that if police spot her at the scene, they could pin a crime on her that she didn’t commit, or later identify her online, which could put her friends and family at risk.

Young Hong Kong protesters also employ other tactics to cover their digital tracks, such as organizing themselves on encrypted app Telegram, using new SIM cards and single-journey subway tickets, rather than travel cards registered to their names, and adopting code names while talking to one another at demonstrations.
Umbrellas are also widely used to block security cameras, ward off tear gas and provide cover for those painting slogans on walls or unscrewing metal railings from the sidewalk. In recent weeks, protesters have strategically used laser pointers to blind security cameras and distract the police.

The 22-year-old volunteer first aider said that these ideas form organically from online discussions.
A police spokesperson would not disclose why they did so, for operational reasons. But the material helps prevent observers from identifying the wearer, as their eyes are hidden from view. A post on online forum LIHKG, the city’s answer to Reddit, instructs protesters where to affix it to hide their identity.

Urban said his website has experienced a spike in hits from Hong Kong, as a result of the recent protests.
“I’m not trying to hawk a product,” Urban said in a phone interview. “I’m just trying to tell people that when your face becomes your identity, there’s no going back. You’re going to be tracked constantly in any public space.”
So can the ideas proposed by artists and designers keep up with the ever-improving technology? And can protesters stay ahead of the developments?
Garfield Benjamin, who researches privacy and digital culture at Britain’s Solent University, said while concepts might work when they are proposed, they can quickly be rendered obsolete because technology is developing so rapidly.
“It’s a bit of an arms race,” Benjamin said.
That’s because the technology powering facial recognition software is becoming ever more complex.
Some systems now can use machine learning to mimic the way humans recognize each other, according to Lujo Bauer, a professor of electrical and computer engineering and computer science at Carnegie Mellon University.
Other software uses infrared light to create 3D models of a person’s face — the kind of technology used on an iPhone X. These examples are more advanced than simply measuring the distances between facial features.
For now, authorities around the world are mostly using 2D facial recognition technology, which isn’t able to recognize depth, said Anil Jain, a computer science professor at Michigan State University. He added that governments may already have access to huge databases of citizens’ photos — such as driver’s license pictures or mugshots — which they can compare with facial recognition data in order to identify individuals.
In mainland China — which operates under a separate legal system from Hong Kong — facial recognition technology, according to Human Rights Watch, is already being used with chilling effects.
Is facial recognition technology too powerful?
Mass surveillance using facial recognition software relies on infrastructure; and without a web of cameras capturing images of citizens the technology cannot be implemented.
A report released by the consumer technology website found that eight of the 10 most surveilled cities in the world are in China. London and Atlanta also made the top 10 cities based on the number of CCTV cameras per 1,000 people and Singapore, Sydney and Delhi made the top 20.

But Hong Kong’s protesters aren’t just concerned about the short-term issue of being arrested by police.
As a 20-year-old student protester — who only gave his surname, Lau — took a break in the shade during a protest on a blazingly hot day, he kept his face mask on, even though no police were around.
“We are not prepared to be picked up by the government yet,” he said.
