> The nymity slider - A simple visualisation of transaction identifiability

September 19, 2022 - Privacy is a really interesting subject, but some of its terminology can be difficult to access. That's why I want to share the nymity slider with you. The nymity slider is a tool to visualise the amount of identifiable information in an interaction. It allows us to assess the level of privacy in a transaction that's easy to grasp regardless of privacy expertise. We will see how the nymity slider can help in designing systems and identifying privacy risks, with a free worksheet at the end.

August 01, 2022 - Recently I came across the Dutch Wikipedia page for privacy. It mentions that one of the major dictionaries states that the word privacy appeared in the Dutch language after 1950. However, the Dutch National Library archives show that privacy can be traced back to at least 1884 as a foreign term. It's used on its own in the Dutch language since at least 1912.

> EU2019: Which MEPs voted in favour of digital rights?

May 08, 2019 - With the European elections in two weeks, it's astounding how little the campaigns talk about digital rights. Just two months ago, thousands of people took to the street to protest Article 13. They were backed up by 5 million signatures on an online petition. They stood up for digital rights, only for our representative politicians to keep quiet. If they won't talk about them, we can at least look at how they acted: by analysing their voting history.

> Unjust Technology Legislation II - The public reaction

January 30, 2019 - In the second part of this series, we take a look at technology legislation after 9/11 and the American response. All but one of the laws discussed were drafted before the full scope of US surveillance became known. Even so, the public began to speak up.
