Implementing TLS Encrypted Client Hello
Posted on November 30, 2021
| Hans-Christoph Steiner
As part of the DEfO project, we have been working on accelerating the development Encrypted Client Hello (ECH) as standardized by the IETF. ECH is the next step in improving Transport Layer Security (TLS). TLS is one of the basic building blocks of the internet, it is what puts the S in HTTPS. The ECH standard is nearing completion. That is exciting because ECH can encrypt the last plaintext TLS metadata that it is possible to encrypt.

IETF112 - Meeting Update (November 2021)
Posted on November 24, 2021
| David
The 112th meeting of the Internet Engineering Task Force (IETF) took place November 8-12, 2021 - as a virtual event for the sixth time in succession due to the COVID-19 pandemic. Here’s a summary of the work I found important to the Internet Freedom community.
Privacy Preserving Measurement While we often (rightly) focus on unwanted surveillance of targeted individuals by nation-states and other bad actors, the Internet’s surveillance economy presents a major threat to personal privacy and freedom for all users of the Internet, as Mozilla so aptly describes on this wiki page.

The IETF and Internet Freedom
Posted on October 18, 2021
| David
It seems useful to clarify the relationship between the near-term work of keeping the Internet open on a daily basis - work that dominates the efforts of the Internet Freedom community - and the long term work of the industry on crafting operational standards for the same network.
Those involved in Internet Freedom are typically focused on the “problems of today”, creating solutions using existing technologies offering immediate effect. Often, it’s hard to tell if Internet standards are helping, hurting, or just in the way.

New insights into clean analytics
Posted on March 2, 2021
| Hans-Christoph Steiner
There is a giant problem with the “collect it all” status quo that pervades on the Internet, this has been clear for a long time. Tracking people has become so widespread that organizations, communities, projects and university labs have sprung up dedicated to detecting and publicizing their presence. Data and analytics are clearly useful for software creators and funders, but they also easily lead to harming people’s privacy and well-being.

Usability: the wonderful, powerful idea that betrayed us
Posted on February 18, 2021
| Hans-Christoph Steiner
Usability triggered a revolution in computing, taking arcane number crunching machines and making them essential tools in so many human endeavors, even those that have little to do with mathematics. It turned the traditional design approach on its head. Initially, experts first built a system then trained users to follow it. User experience design starts with goals, observes how people actually think and act in the relevant context, then designs around those observations, and tests with users to ensure it fits the users’ understanding.

New Data Sources: API Key Identifiers and BroadcastReceiver Declarations
Posted on December 15, 2020
| Hans-Christoph Steiner
A central focus of the Tracking the Trackers project has been to find simple ways to detect whether a given Android APK app file contains code which tracks the user. The ideal scenario is a simple program that can scan the APK and tell a non-technical user whether it contains trackers, but as decades of experience with anti-virus and malware scanners have clearly demonstrated, scanners will always contain a large degree of approximation and guesswork.

εxodus ETIP: The Canonical Database for Tracking Trackers
Posted on December 11, 2020
| Hans-Christoph Steiner
There is a new story to add to the list of horrors of Surveillance Capitalism: the United States’ Military is purchasing tracking and location data from companies that track many millions of people. We believe the best solution starts with making people aware of the problem, with tools like Exodus Privacy. Then they must have real options for stepping out of “big tech”, where tracking dominates. F-Droid provides Android apps that are reviewed for tracking and other “anti-features”, and F-Droid is built into mobile platforms like CalyxOS that are free of proprietary, big tech software.

Distribution in Depth: Mirrors as a Source of Resiliency
Posted on December 7, 2020
| Hans-Christoph Steiner
There are many ways to get the apps and media, even when the Internet is expensive, slow, blocked, or even completely unavailable. Censorshop circumvention tools from ShadowSocks to Pluggable Transports can evade blocks. Sneakernets and nearby connections work without any network connection. Hosting on Content Delivery Networks (CDNs) can make hosting drastically cheaper and faster. One method that is often overlooked these days is repository mirrors. Distribution setups that support mirrors give users the flexibility to find a huge array of solutions for problems when things are not just working.

When disaster strikes, our mobile devices can provide us with many tools to deal with a wide variety of problems. The internet is not available in every corner of the planet, and large scale outages happen. Digital maps allow us to carry detailed maps of the entire planet in our pockets. And the good map apps allow the user to download entire regions to the device so that they operate without internet at all.

Easy translation workflows and the risks of translating in the cloud
Posted on June 8, 2020
| Hans-Christoph Steiner
Crowdsourced translation has opened up software and websites to whole new languages, regions, and uses. Making translating easier has brought in more contributors, and deploying those languages requires less work. A number of providers now offer “live”, integrated translation, speeding up the process of delivering translated websites. On the surface, this looks like a big win. Unfortunately, the way such services have been implemented opens up a big can of worms.

On the classification of tracking
Posted on May 20, 2020
| Aaron Kaplan
This position paper tries to outline a framework for defining trackers in smart phones and lists mechanisms for identifying them. It hopes to serve as the foundation for the work done in the Tracking-the-Trackers project.
In section 1 we start with an abstract analysis of levels of unwanted behaviour in the context of tracking.
Next, in section 2, we focus on an attacker’s perspective, on anonymity and pseudonymity. This foundation allows us to define terms which are needed throughout the paper.

Free Software Tooling for Android Feature Extraction
Posted on May 6, 2020
| Hans-Christoph Steiner
As part of the Tracking the Trackers project, we are inspecting thousands of Android apps to see what kinds of tracking we can find. We are looking at both the binary APK files as well as the source code. Source code is of course easy to inspect, since it is already a form that is meant to be read and reviewed by people. Android APK binaries are a very different story.

"Features" for Finding Trackers
Posted on April 28, 2020
| Hamilton Kaplan
One key component of the Tracking the Trackers project is building a machine learning (ML) tool to aide humans to find tracking in Android apps. One of the most important pieces of developing a machine learning tool is figuring out which “features” should be fed to the machine learning algorithms. In this context, features are constrained data sets derived from the whole data set. In our case, the whole data set is terabytes of APKs.

Figuring Out Crowdsourced Translation of Websites
Posted on April 23, 2020
| Hans-Christoph Steiner
Crowdsourced translation platforms like Weblate, Transifex, Crowdin, etc. have proven to be a hugely productive way to actively translate apps and desktop software. Long form texts like documentation and websites remain much more work to translate and keep translated. Many translation services currently support Markdown and HTML, but very basically, which means much more work for translators and webmasters. Translators can inadvertently break things, either with a typo or because of a lack of knowledge of a specific syntax.

The Promise and Hazards of COVID Contact Tracing Apps
Posted on April 9, 2020
| Hans-Christoph Steiner
There has been increasing interest in the possibilities of tracking people who are infected with Coronavirus using all of the various methods that smart phones provide. There is good reason: “contact tracing” has been a pillar of public health efforts for decades. It is an effective means to curtail the spread of infectious disease. At the same time, governments, companies, and organizations are acting fast to offer services to help end this current pandemic.

Improving Crowdsourced Translation of Long Form Text
Posted on March 5, 2020
| Hans-Christoph Steiner
We are happy to announce the start of work on another step in improving crowdsourced localization, funded by the ISC Project. This is the second part of our ongoing “Linguine” collaboration to move crowdsourced translation to privacy-respecting free software.
Crowdsourced translation has proven enormously successful getting apps and website software translated into many languages. Using tools like Weblate or Transifex, developers can quite easily incorporate translated app strings into their mobile apps and websites.
