Researchers develop tool to Detect Voice Liveness Detection to prevent voice-spoofing attacks. Australias Commonwealth Scientific and Industrial Research Organization have developed a system called Void short for Voice liveness Detection. The idea is to quickly detect whether a device is live or is prerecorded. A research paper describing Void will be presented at the USENIX Security Symposium in Boston in August. The system needs to work quickly, it needs to have a low overhead on a device, and, crucially, it also needs a low false positive rate.”]
