Privacy – White elephant in the room with COVID-19?

If it’s one thing life has taught me, “almost” everything has a price. For a good sum, you can get a person to sell his phone. For others, something else. It’s known fact that we live in the world of data.

Everything we do today generates data. Every step you take, every move you make (no its not a song), every interaction. Our lives have become a digital data lake, filled with details of what happens. Data can be in many forms. Audio – forms of conversations. Video – CCTV footages. Logs of transactions, usage, and patterns that is formed based on behavior.

In 2018, Strava, a company that produces fitness tracking solution had inadvertently revealed secret military base due to its users heatmap. The visualization component of the app provided heat maps on user clustering, which indicated secret military presence. This wasn’t the outcome Strava had foreseen, but undoubtedly become prevalent.

I have a saying about data. “Once you create data/information, you are forever doomed to tend to it till it ceases to exist”. Something like Sisyphus, who was condemned to rolling the stone up the mountain, only to find it back down the very next day.

If you attend a conference and visit the booths just for a “look-see”, you most often find a simple glass bowl. In it, a stack of name cards. Name cards are wealth of personal information. One could argue that its corporate information, which is apt. However you’d also find mobile phone numbers. Unless if those are company issued (remember the good ol days of Blackberry?), you’ve just handed over your personal mobile phone number to (not one) but countless number of individuals who will have access to that information. Ever wonder how a completely unknown sales person calls you up for similar products…. *cricket sound*

Ironically all that for a “possibility” of winning <insert the latest gadget name> or a booth token/premium. I remember the time when we went to a week long debate about managing personal information in the form of name cards in context of whether it is a business or a personal venture during the implementation of Malaysia’s PDPA for a telco, together with then the Commissioner of PDPC.

With MCO, contact tracing became a “new normal” (see I can also do buzzwords). Contract tracing is when the outlet you visit requires you to put your details such as name, phone number and temperature. It’s implemented quite simply, using a piece of paper or a book with the visitor jotting down his/her details. Just hypothetically, if you see a person of interest walking up to the same outlet, all one has to do is glean over and note down the number that was written on the contact log. There’s 2 school of thoughts on this matter. First, the contact details given, in some instances, are bogus to prevent such exact situation, which sadly defeats the purpose. Second, it’s a requirement, hence the burden of protecting such information belongs to the establishment collecting that information…. *cricket sound*

Point to note, what happens after MCO? Is the log book going to end up in a dump somewhere with all of the contact details?

What about contact tracing apps? I’d like to cite the example of AarogyaSetu app from India. When it was initially launched, the creators were barraged with queries of privacy and surveillance, which eventually lead to the app being open sourced. While the code was open sourced, upon closer inspection reveals that it has a few critical missing parts, and also found that it was retaining logs of other devices the app had come into contact with ( a database inside the app stores all of the Bluetooth addresses). The internet community celebrated its victory, having to compel the authors to publish the codes on Github.

The importance of having such applications being code published are a few. The codes allow the collective hive of internet to find any potential bugs or issues which allows the app to be improved and become safer over time. The transparency of code helps to allay fears of surveillance and privacy concerns. There’s research done on privacy preserving scheme which can be used to ensure that the app only captures relevant information. In an increasing rise of police state, such as the Black Lives Matter movement (re: George Floyd) in the US and worldwide, having such steps shows commitment of the respective nation states to their rakyats (meaning citizen in Malay). It’s been seen that data leakages happen due to poor security on the backend (such as exposed data buckets on the internet).

There is no doubt, the new normal has everyone getting adjusted into doing things differently. But that doesn’t mean privacy needs to take a back seat. Things can be done in proper manner, just needs some serious thought through. Age of smart phones has made it much easier for anyone and everyone to do contact tracing easily, but it also comes with serious fore-thought for it to be effective.

In Malaysia, we have a number of mobile apps. State government of Selangor published the “SeLangkah” app to do simple contact tracing. Malaysian central government introduced MySejahtera and MyTrace for COVID-19 tracking. MySejahtera has been seen to be adopted as part of the wider strategy while SeLangkah seems to be most retailer’s choice.

With these apps in place, in Malaysia, there are questions left hanging

  1. What are the security considerations and controls put in place to ensure that the mobile application is secure?
  2. Will the codes be published (quoting the Minister of MOSTI who made the statement on 10 May 2020) ?
  3. Where is the data captured by these apps stored? Are those storage secure? Who has access to those data? What type of data is secured?
  4. How is the security of the backend servers and services of these mobile applications?
  5. Has the mobile app undergone necessary security validation (i.e. vulnerability assessment/penetration testing/code audits)?
  6. What happens after the Movement Control Order (MCO) dismantled? What happens to the application and the data being captured? Whose responsible in enduring that the data is not kept beyond its use and disposed securely?
