Getty Images / WIRED The UK is planning a new attack on end-to-end encryption, with the Home Office set to spearhead efforts designed to discourage Facebook from further rolling out the technology to its messaging apps. Home Secretary Priti Patel is planning to deliver a keynote speech at a child protection charity’s event focused on exposing the perceived ills of end-to-end encryption and asking for stricter regulation of the technology. At the same time a new report will say that technology companies need to do more to protect children online. Advertisement Patel will headline an April 19 roundtable organised by the National Society for the Prevention of Cruelty to Children (NSPCC), according to a draft invitation seen by WIRED. The event is set to be deeply critical of the encryption standard, which makes it harder for investigators and technology companies to monitor communications between people and detect child grooming or illicit content, including terror or child abuse imagery.
