“If the UK decides that it is OK for a government to get rid of encryption, there are governments all around the world that will do exactly the same thing, where liberal democracy is not as strong,” he said.Ī Home Office spokesperson said the online safety bill, which is due to become law this year, does not ban encryption. Will Cathcart, the head of WhatsApp, told the Financial Times last year that any UK move against encryption would have reverberations around the world. She added that technological “back doors” into encrypted services could be hijacked by “malignant state actors” and “create a way for criminals to access these systems”.

Whittaker said such a system would turn everyone’s phone into a “mass surveillance device that phones home to tech corporations and governments and private entities”.

In 2021 Apple was forced to pause its client-side scanning plans, which would have involved the company scanning user photos before they are uploaded to its image-sharing service. Whittaker also criticised a system called client-side scanning, where images are scanned before being encrypted. End-to-end encryption ensures that only the sender and recipient of a message can view its content. Signal, which has been downloaded more than 100m times on Google’s app store, is operated by a US-based nonprofit organisation and is widely used by activists and journalists, as well as some intelligence services. She said: “Encryption is either protecting everyone or it is broken for everyone.” Whittaker told the BBC it was “magical thinking” to believe there can be privacy “but only for the good guys”, adding that the bill was an example of this thinking. Privacy advocates warn the bill could force encrypted messaging services such as Signal, WhatsApp and Apple’s iMessage to monitor users’ messages and create vulnerabilities in their platforms that could be exploited by rogue actors and governments.
