ENCRYPTIONThe U.K. Government Is Very Close to Eroding Encryption Worldwide

The Online Safety Bill, now at the final stage before passage in the House of Lords, gives the British government the ability to force backdoors into messaging services, which will destroy end-to-end encryption. If it passes, the Online Safety Bill will be a huge step backwards for global privacy, and democracy itself.

The U.K. Parliament is pushing ahead with a sprawling internet regulation bill that will, among other things, undermine the privacy of people around the world. The Online Safety Bill, now at the final stage before passage in the House of Lords, gives the British government the ability to force backdoors into messaging services, which will destroy end-to-end encryption. No amendments have been accepted that would mitigate the bill’s most dangerous elements. 

If it passes, the Online Safety Bill will be a huge step backwards for global privacy, and democracy itself. Requiring government-approved software in peoples’ messaging services is an awful precedent. If the Online Safety Bill becomes British law, the damage it causes won’t stop at the borders of the U.K. 

The sprawling bill, which originated in a white paper on “online harms” that’s now more than four years old, would be the most wide-ranging internet regulation ever passed. At EFF, we’ve been clearly speaking about its disastrous effects for more than a year now. 

It would require content filtering, as well as age checks to access erotic content. The bill also requires detailed reports about online activity to be sent to the government. Here, we’re discussing just one fatally flawed aspect of OSB—how it will break encryption. 

An Obvious Threat to Human Rights
It’s a basic human right to have a private conversation. To have those rights realized in the digital world, the best technology we have is end-to-end encryption. And it’s utterly incompatible with the government-approved message-scanning technology required in the Online Safety Bill. 

This is because of something that EFF has been saying for years—there is no backdoor to encryption that only gets used by the “good guys.” Undermining encryption, whether by banning it, pressuring companies away from it, or requiring client side scanning, will be a boon to bad actors and authoritarian states.

The U.K. government wants to grant itself the right to scan every message online for content related to child abuse or terrorism—and says it will still, somehow, magically, protect peoples’ privacy. That’s simply impossible. U.K. civil society groups have condemned the bill, as have technical experts and human rights groups around the world
