Apple working on an iPhone even it can't hack

Washington

APPLE engineers have already begun developing security measures that would make it impossible for the government to break into a locked iPhone using methods similar to those at the centre of a court fight in California, according to people close to the company and security experts.

If Apple succeeds in upgrading its security - and experts say it almost surely will - the company will create a significant technical challenge for law enforcement agencies, even if the Obama administration wins its fight over access to data stored on an iPhone used by one of the killers in last year's San Bernardino, California rampage.
