UK home secretary Amber Rudd has called on messaging apps like WhatsApp to ditch end-to-end encryption, arguing that it aids terrorists. From a report: The major technology companies must step up their fight against extremism or face new laws, the home secretary has told the BBC. Amber Rudd said technology companies were not doing enough to beat "the enemy" on the internet. Encryption tools used by messaging apps had become a "problem," she added. Ms Rudd is meeting with representatives from Google, Facebook, Twitter, Microsoft and others at a counter-terrorism forum in San Francisco. Tuesday's summit is the first gathering of the Global Internet Forum to Counter Terrorism, an organisation set up by the major companies in the wake of recent terror attacks. In a joint statement, the companies taking part said they were co-operating to "substantially disrupt terrorists' ability to use the internet in furthering their causes, while also respecting human rights." In an op-ed, she wrote Tuesday: Real people often prefer ease of use and a multitude of features to perfect, unbreakable security ... Who uses WhatsApp because it is end-to-end encrypted, rather than because it is an incredibly user-friendly and cheap way of staying in touch with friends and family? Companies are constantly making trade-offs between security and 'usability,' and it is here where our experts believe opportunities may lie.
