I was going to write about how Apple's new detector for child sexual abuse material (CSAM), promoted under the umbrella of child protection and privacy, is a firm step towards prevalent surveillance and control, but many others have already written so good stuff. Some of it 👇 First, don't be fooled by the fancy crypto and the flashy privacy claims. This is a backdoor to encryption. Yes, folks, a privacy-preserving backdoor is no less of a backdoor. We are back to the crypto wars. @EFF goes at lenght about this in their analysis eff.org/deeplinks/2021…

We hear that the Digital Green Certificate (DGC) is good news as it will enable "safe free movement". Safe free movement is great news, the technical proposal not so much

A long thread coming 👇

This thread is based on three documents:

Technical proposal: ec.europa.eu/health/sites/h…

Yesterday, I had a business lunch. The restaurant asked me to input my data on SocialPass, an app now mandatory in Canton Vaud for restaurants gastrovaud.ch/coordonnees-de…
I get the need for tracking, not the creation of abusive surveillance infrastrutures ignoring data protection👇 The app is extremely invasive. The designers have not heard of Data Minimization. It is unclear why my address, my name, or *my date of birth!* is at all necessary for a tracer to call me (yes, all fields mandatory and phone number checked via SMSa)

As countries deploy data-hungry contact tracing, we worry about what will happen with this data. Together with colleagues from 7 institutions, we designed a system that hides all personal information from the server. Please read and give comments! More info in our repo: github.com/DP-3T/
