Imagine this: a power that secretly orders someone anywhere in the world to abide and the receiver can’t tell anyone, can’t even publicly say if they disagree, and can’t really question the power in open court because the secret order is, well, secret. Oh and that power affects billions of people’s security and their data. And despite being affected, we too can’t question the secret order.In this piece we will outline what’s ridiculous, the absurd, and the downright disturbing about what’s…

Edit: 13 March 2025 - You can find more about what happened next on our case pageOn February 21st, Apple disabled their ‘advanced data protection’ service for UK customers. That means no-one in Great Britain can now enable a powerful security safeguard that people who use Apple devices everywhere else on the planet can: user controlled end-to-end encryption of stored data.This is likely in response to a disturbing secret government power. Well, that’s what we think happened. We can’t know for…

In response, the UK Parliament passed the highly controversial Investigatory Powers Act 2016 (IPA), which authorised massive, suspicionless surveillance on a scale never seen before, with insufficient safeguards or independent oversight.Privacy International led legal challenges to this mass surveillance regime both before and after the Act became law. The Act…

We are responding to the UK Government's consultation to expand its powers around Technical Capabilities Notices and National Security Notices.

One of the powers it added was the ability to issue…

End-to-end encryption (E2EE) contributes significantly to security and privacy. For that reason, PI has long been in favour of the deployment of robust E2EE.Encryption is a way of securing digital communications using mathematical algorithms that protect the content of a communication while in transmission or storage. It has become essential to our modern digital communications, from personal emails to bank transactions. End-to-end encryption is a form of encryption that is even more private.…

What happened
On 22 July 2021, the Investigatory Powers Tribunal (IPT) issued a declaration on our challenge to the UK bulk communications regime finding that section 94 of the Telecommunications Act 1984 (since repealed by the Investigatory Powers Act 2016) was incompatible with EU law human rights standards. The result of the judgment is that a decade’s worth of secret data capture has been held to be unlawful. The unlawfulness would have remained a secret but for PI’s work.
