The debate and legal fight over whether the government can force tech companies to unlock personal devices in the name of national security is far from over, according to FBI Director James Comey.
The agency's chief told a group of reporters on Wednesday that tech companies should expect more litigation in the future over the FBI seeking access to users' electronic devices and encrypted information, according to a Reuters report.
Comey pointed to encryption as the "essential tradecraft" that terrorists such as the Islamic State use. He noted that questions surrounding the government's right to force tech companies to unlock users' devices have turned into a fight that will go on, Reuters reported.
Despite the fact that messaging service WhatsApp's recently unveiled end-to-end encryption, which is "affecting the criminal work (of the FBI) in huge ways," he has no plans to sue WhatsApp's parent company Facebook, according to Reuters.
But the agency wasn't shy in launching a high-profile lawsuit against Apple, following the San Bernardino terrorist attack late last year. The FBI wasn't able to unlock the encryption on terrorist Syed Farook's iPhone, and demanded that Apple create a backdoor to allow access. That lawsuit was dropped after the FBI hired a hacker who was successful in cracking into the iPhone.
Comey said that of the 4,000 devices examined by agency experts since October, they have failed to unlock 500 phones -- which have different operating systems and model-types from Farook's iPhone, according to Reuters. However, the FBI is looking into how to use the same tool used in the Farook case to unlock other phones, the report added.
As a result, the debate over encrypted devices is not likely to go away anytime soon. Last month, for example, Congress held a hearing to confront the issue of encrypted devices and whether law enforcement should have the ability to lawfully access these devices and communications.
Although the hearing did not produce any concrete plan of action, there is other movement afoot in this area. In March, an encryption working group was formed by lawmakers to explore potential uses and regulation of encryption. There's also legislation that's been introduced that would address backdoors in encrypted devices, according to a TechCrunch report.
