Abstract
A system is disclosed that includes a processor including watermark logic to output a first watermark to an output device that outputs a first watermark signal, based on the first watermark, to an acoustic transmission medium. The processor also includes recording logic to capture, at a first time period, an authentication submission comprising the first watermark signal convolved, via the acoustic transmission medium, with a first passphrase signal. The system also includes a dynamic random access memory (DRAM). Other embodiments are disclosed and claimed.
