You should listen to and read what experts have to say on the topic or privacy.
I offer three sources who are prolific on the topic.
The first is Canadian Michael Geist - a law professor at the University of Ottawa where he holds the Canada Research Chair in Internet and E-commerce Law and is a member of the Centre for Law, Technology and Society. Here's his column archive, you can also find a podcast and more writing on this site.
One title that should jump out at you, given our current use of social media and other digital tools from other countries and companies: "Does Canadian Privacy Law Matter if it Can’t be Enforced?"
Second is U of T's Citizen Lab.
"The Citizen Lab is an interdisciplinary laboratory based at the Munk School of Global Affairs & Public Policy, University of Toronto, focusing on research and development at the intersection of information and communication technologies, human rights, and global security."
A mouthful. But, some recent research reports and what they found are essential reading:
Bots at the Gate: A Human Rights Analysis of Automated Decision Making in Canada’s Immigration and Refugee System
"The report finds that use of automated decision-making technologies to augment or replace human judgment threatens to violate domestic and international human rights law, with alarming implications for the fundamental human rights of those subjected to these technologies."
An Analysis of WeChat’s Realtime Image Filtering in Chats.
"In this work, we study how Tencent implements image filtering on WeChat. We found that Tencent implements realtime, automatic censorship of chat images on WeChat based on what text is in an image and based on an image’s visual similarity to those on a blacklist. Tencent facilitates this realtime filtering by maintaining a hash index of MD5 hashes of sensitive image files."
The Predator in Your Pocket: A Multidisciplinary Assessment of the Stalkerware Application Industry
"This report was collaboratively written by researchers from computer science, political science, criminology, law, and journalism studies. As befits their expertise, the report is divided into several parts, with each focusing on specific aspects of the consumer spyware ecosystem, which includes: technical elements associated stalkerware applications, stalkerware companies’ marketing activities and public policies, and these companies’ compliance with Canadian federal commercial privacy legislation."
And, finally, expert public-interest technologist Bruce Schneier's Crypto-Gram is very much worth your time, and important to read. You should also subscribe.
"A free monthly newsletter providing summaries, analyses, insights, and commentaries on security: computer and otherwise."
Every month you'll get deep insights into things like Identity Theft on the Job Market, Brazilian Cell Phone Hack, More on Backdooring (or Not) WhatsApp, Zoom Vulnerability, and more.
