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.
Claims20
An apparatus, comprising:
- one or more processors;
- and
- a storage disk or memory including machine-readable instructions that, when executed, cause the one or more processors to:
- access an authentication standard including a first acoustically watermarked passphrase, the first acoustically watermarked passphrase having a first acoustic watermark and a first acoustic passphrase acoustically mixed with the first acoustic watermark during a first time period via a first common acoustic medium, the first acoustic watermark output by an acoustic output transducer during the first time period, the first acoustic passphrase spoken by a user during the first time period, the first acoustic watermark and the first acoustic passphrase captured by an acoustic input transducer during the first time period;
- access an authentication submission including a second acoustically watermarked passphrase, the second acoustically watermarked passphrase having a second acoustic watermark and a second acoustic passphrase acoustically mixed with the second acoustic watermark during a second time period subsequent to the first time period via a second common acoustic medium, at least a portion of the second acoustic watermark output by the acoustic output transducer during the second time period, the second acoustic watermark and the second acoustic passphrase captured by the acoustic input transducer during the second time period;
- determine whether a first timestamp embedded in the first acoustic watermark matches a second timestamp embedded in the second acoustic watermark;
- and
- deny authentication in response to determining that the second timestamp matches the first timestamp.
