WhatsApp, the Facebook-owned maker of an instant-messaging app, may face the same legal conundrum as Apple in a case that centers on the thorny issue of privacy versus security.
The US Department of Justice is eager to view a series of WhatsApp messages for a criminal investigation, a move that has been given the go-ahead by a federal judge, The New York Times reported Saturday. But the messages are encrypted, meaning no one, not even WhatsApp, can unscramble them so that they’re readable.
The Justice Department is reportedly trying to decide if it should ask a judge to force WhatsApp to find a way to decode the messages. That’s the course it’s already taking in its battle with Apple, in which the company is pushing back against a court order to unlock the data on an iPhone 5C used by one of the terrorists who killed 14 people in San Bernardino, California, in December.
