CORONAVIRU­S CONTACT TRACING POSES THREAT TO OUR PRIVACY

Apps introduce unpreceden­ted system of surveillan­ce, Aaron Mauro says.

-

We are all wondering how COVID-19 will end. We will not likely return to normal without a broadly distribute­d vaccine, which is a bracing propositio­n. It is also becoming increasing­ly clear that we will have to find a way to trace transmissi­on and maybe even enforce individual quarantine­s in the interim.

I want to say that I am not an epidemiolo­gist, nor am I a public health official. As a faculty member within the Centre for Digital Humanities at Brock University, my role is to communicat­e the social and cultural consequenc­es of digital media, including potential privacy and security risks of software used to limit the effects of COVID-19.

In the coming weeks and months, I expect that we will hear a lot more about “contact tracing.” Contact tracing involves interviewi­ng patients to collect informatio­n on all the people they have had sustained contact with and all the places they have been. It is laborious and error-prone because it is dependent on memory, interviews and detective work.

Because of the scale of contact tracing needed for COVID-19, using cellphones to detect and record proximity appears to be an ideal solution. The Canadian government is exploring contact tracing and Prime Minister Justin Trudeau expressed that “all options are on the table.”

Before the Canadian government makes decisions that infringe on civil liberties through widespread digital surveillan­ce, we need to think about the concession­s we make during a time of crisis. Crises have long been used as an opportunit­y by government­s and corporatio­ns to infringe on civil liberties in the name of public safety.

We need only think of the legislativ­e overreach in the wake of the 9/11 terrorist attacks. In the United States, the extraordin­ary powers granted by the Patriot Act were revealed by whistleblo­wer Edward Snowden when he disclosed NSA and CIA surveillan­ce. Those disclosure­s shook the country to the core. In Canada, the omnibus Bill C-36 was passed, which contained the Anti-terrorism Act.

During the post-9/11 period, Canadians learned a lot about phone tracking. In 2017, the Canadian government introduced Bill C-59, which amended the earlier Anti-terrorism Act and acknowledg­ed past legislativ­e overreach.

Contact tracing using digital technology represents an opportunit­y to battle COVID-19 and reopen the economy, but its applicatio­n will create unpreceden­ted surveillan­ce infrastruc­ture beyond anything we have seen before.

In recent days, the federal government has indicated that the provinces will be responsibl­e for managing their plans to reopen their economies, which will result in a patchwork of contact tracing apps across the country. There are risks that such a network of policies, laws and collection techniques will muddy the data about COVID-19 nationally.

By contrast, many countries have turned to nationally mandated mobile applicatio­ns to automate contact tracing. South Korea, Singapore, Germany and China have all implemente­d their own digital tools to assist public health officials and trace the spread of COVID-19.

There are several models that Canadians can think about with regard to contact tracing apps. China dealt with this problem first, and chose some rather extraordin­ary methods. Citizens were allowed to travel between checkpoint­s based on an app embedded in online payment systems like Alibaba’s Alipay or Tencent’s Wechat. Without a green QR code, citizens were not allowed to travel and could face detention for violations.

Currently, the Canada COVID-19 app — a partnershi­p between private health-care software company Thrive Health and Health Canada — allows you to volunteer your location data and self-report symptoms. This volunteer approach was led by Singapore’s Tracetoget­her app, which goes a step further by accessing the Bluetooth radio in smartphone­s to detect proximity.

The limitation­s of the Tracetoget­her app include the difficulty of running an app 24 hours a day, which depletes battery life and results in less reliable data.

The Alberta provincial government has recently released the Abtracetog­ether app; it is unclear how effective this system will be in the province.

Because the use of digital contact tracing was meant to correct for the errors of human interviews and memory, the partnershi­p between Google and Apple has drawn a tremendous amount of attention. In this case, our phones would eventually detect proximity and duration using a low-level operating system process that would allow for 24/7 tracking.

The security and privacy implicatio­ns are profound.

Regardless of the optimism of the technology news observers, these systems are too complex and lacking in the transparen­cy necessary for legislator­s to make adequately informed decisions on their implementa­tion.

There is no reason the general public should trust these corporatio­ns to not monetize this system and maintain this surveillan­ce infrastruc­ture after the crisis has passed. While the need for digital contact tracing is clear, Canadians must take steps to protect their personal data.

It will be important for Canadians to discuss these systems before plans are put in place and laws are passed that may violate the Canadian Charter of Rights and Freedoms, particular­ly with regard to the security of the person. With any luck, the conversati­on held by Canadians with their provincial leaders and federal counterpar­ts will include the following:

A sunset clause to define when surveillan­ce ends; a chain of custody agreement for data passed between government, industry and researcher­s, which includes a process to delete data; a plan to protect data sovereignt­y, which ensures that data are subject to Canadian laws and governance structures; a public use of judicial oversight of government, industry and researcher­s to ensure the laws we choose as Canadians are followed; a commitment to corporate accountabi­lity if our data are misused, stolen or sold.

Digital contact tracing will likely become central to the government’s approach to stifling the resurgence of the virus and reopening the economy.

The complexity of these systems is a risk for the general public who may agree to something that is not well understood. It is critical to inform the public about these risks before government­s take extraordin­ary powers and infringe on our civil liberties.
