Plan for massive facial recognition database sparks privacy concerns

If you’ve had a driver’s licence photo or passport photo taken in Australia in the past few years, it’s likely your face will end up in a massive new national network the federal government is trying to create.

Victoria and Tasmania have already begun to upload driver’s licence details to state databases that will eventually be linked to a future national one.

Legislation before federal parliament will allow government agencies and private businesses to access facial IDs held by state and territory traffic authorities, and passport photos held by the foreign affairs department.

The justification for what would be the most significant compulsory collection of personal data since My Health Record is cracking down on identity fraud.

The home affairs department estimates that the annual cost of ID fraud is $2.2bn, and says introducing a facial component to the government’s document verification service would help prevent it.

The verification service is already used by 100 government agencies and 700 businesses, carrying out more than 30m ID checks in 2017 alone.

What is facial recognition - and how sinister is it?

But alongside the document verification service, a facial identification service for law enforcement would be introduced.

Almost all state and territory governments have updated their driver’s licence laws in anticipation of the database after an agreement at the Council of Australian Governments in October 2017, while people getting passports sign a form that states that their photographs will be used for biometric matching purposes.

What are the concerns?

Privacy advocates say the new legislation lacks proportionality – that the benefits do not outweigh the intrusion into people’s privacy.

The Australian Privacy Foundation says the proposal is highly invasive, because the system could be integrated into a number of other systems that collect facial data, including closed-circuit television.

“We are on our way to automated and real-time surveillance of public spaces,” the foundation says.

In Hong Kong in August, pro-democracy protesters were seen using an electric saw to cut down a lamp post. It was a fightback against government surveillance, with fears the cameras in the post were using facial recognition technology so the Chinese government could identify the activists.

This might seem a world away, but when the Gold Coast hosted the Commonwealth Games last year, Queensland police trialled facial recognition software on CCTV footage of crowds to identify 16 high-profile targets.

Halfway through the trial, police extended it to general policing, though they were only able to find five people out of 268 plugged into the system.

False positives are a massive problem plaguing the effectiveness of the system. London’s Metropolitan Police used automated facial recognition in trials in 2016 and 2017 and reported that more than 98% of matches wrongly identified innocent members of the public. Overall there were 102 false positives.

The Australian Human Rights Commission says facial recognition technology “remains unreliable”.

“If inaccurate information received from the use of this technology is used by law enforcement, it could also have drastic consequences for the person concerned, including being arbitrarily detained and having fundamental features of their right to a fair trial compromised,” the human rights commissioner, Edward Santow, told the parliamentary inquiry.

The Human Rights Law Centre noted that NEC Neoface, a separate facial recognition technology used by federal agencies and some state and territory police, has not been tested for accuracy on different ethnic groups, meaning a potentially disproportionate rates of misidentification of ethnic minorities.

The home affairs department says it conducts testing and tuning of facial recognition software, and matching results will be reviewed by “trained facial recognition experts” to prevent false matches.

“In other words, decisions that serve to identify a person will never be made by technology alone,” the department says.

Trials such as the one at the Commonwealth Games, and a similar schemes in Perth and Brisbane, work on live facial recognition. The scheme proposed by the federal government would be a more manual input process.

The Department of Home Affairs argues that concerns about mass surveillance are not warranted, because it’s just not feasible. They say the systems are not designed for it and there are nowhere near the resources, including personnel sufficiently trained in facial recognition, that would be needed to conduct a mass surveillance program.

The standalone system for law enforcement requires a person to manually submit a person’s image and resolve against possible matches, and it creates an audit trail, the department says.
