2018/06/04: are our smartphones actually listening?
According to Dr. Peter Hannay—The senior security consultant for cybersecurity firm Asterisk, and former lecturer and researcher at Edith Cowan University—the short answer is yes, but perhaps in a way that's not as diabolical as it sounds.
For your smartphone to actually pay attention and record you, there needs to be a trigger, like Hey Siri or Okay Google for example . Without these triggers, there's no recording, with just some general metrics being sent to your service provider. This might not seem a cause for an alarm, but when it comes to apps like Facebook, no one knows what the triggers are. In fact, there could be thousands.
“It’s just an extension from what advertising used to be on television,” says Peter. Only instead of prime time audiences, they’re now tracking web-browsing habits. It’s not ideal, but I don’t think it poses an immediate threat to most people.”
