Spoofing and Anti-Spoofing Technologies of Global Navigation Satellite System: A Survey

Spoofing and Anti-Spoofing Measures

Speaker Recognition Anti-spoofing

Progress in the development of spoofing countermeasures for automatic speaker recognition is less advanced than equivalent work related to other biometric modalities. This chapter outlines the potential for even state-of-the-art automatic speaker recognition systems to be spoofed. While the use of a multitude of different datasets, protocols and metrics complicates the meaningful comparison of ...

Anti-spoofing, Voice Databases

As with any task involving statistical pattern recognition, the assessment of spoofing and anti-spoofing approaches for voice recognition calls for significantscale databases of spoofed speech signals. Depending on the application, these signals should normally reflect spoofing attacks performed prior to acquisition at the sensor or microphone. Since the collection of large quantities of any bi...

Anti-spoofing, Voice

The process of verifying whether the voice sample presented to an authentication system is real (i.e., alive), or whether it is replayed or synthetic, and thus fraudulent. When authentication through a voice authentication system is requested, it is important to be sure that the person seeking the authentication actually provides the required voice sample at the time and place of the authentica...
