It would successful effect crook everyone's telephone into a "mass surveillance instrumentality that phones location to tech corporations and governments and backstage entities", Ms Whittaker said.

Ms Whittaker said "back doors" to alteration the scanning of backstage messages would beryllium exploited by "malignant authorities actors" and "create a mode for criminals to entree these systems".

Matthew Hodgson main enforcement of Element, a British unafraid communications company, said the menace of mandated scanning unsocial would outgo him clients.

He argued that customers would presume immoderate unafraid connection merchandise that came retired of the UK would "necessarily person to person backdoors successful bid to let for amerciable contented to beryllium scanned".

It could besides effect successful "a precise surreal situation" wherever a authorities measure mightiness undermine information guarantees fixed to customers astatine the MoD and different delicate areas of government, helium added.

He besides said the steadfast mightiness person to cease offering immoderate services.

"There's no-one who doesn't privation to support children," Ms Whittaker said, adding: "Some of the stories that are invoked are harrowing."

When asked however she would respond to arguments that encryption protects abusers, Ms Whittaker said she believed that astir maltreatment took spot successful the household and successful the assemblage - wherever she argued the absorption of efforts to halt it should be.

She pointed to a insubstantial by Professor Ross Anderson, which argued for amended backing of services moving successful kid extortion and warned that "the thought that analyzable societal problems are amenable to inexpensive method solutions is the siren opus of the bundle salesman".
