Abstract
A method for generating an acoustic stimulus for use in an ear biometric process on a user, the method comprising: receiving an indication of stimulation frequencies for use in the ear biometric process; grouping the stimulation frequencies into bands of a psychoacoustic scale; generating the acoustic stimulus, the acoustic stimulus comprising a masked bandpass component within each band of the psychoacoustic scale that comprises one or more of the stimulation frequencies.
Claims20
A method for generating an acoustic stimulus for use in an ear biometric process on a user, the method comprising:
- receiving an indication of stimulation frequencies for use in the ear biometric process;
- grouping the stimulation frequencies into bands of a psychoacoustic scale;
- generating the acoustic stimulus, the acoustic stimulus comprising a masked bandpass component within each band of the psychoacoustic scale that comprises one or more of the stimulation frequencies.
A non-transitory machine-readable medium storing instructions which, when executed by one or more processors, cause an electronic apparatus to perform a method comprising:
- receiving an indication of stimulation frequencies for use in the ear biometric process;
- grouping the stimulation frequencies into bands of a psychoacoustic scale;
- and
- generating the acoustic stimulus, the acoustic stimulus comprising a masked bandpass component within each band of the psychoacoustic scale that comprises one or more of the stimulation frequencies.
An apparatus comprising processing circuitry and a non-transitory machine-readable medium storing instructions which, when executed by the processing circuitry, cause the apparatus to:
- receive an indication of stimulation frequencies for use in the ear biometric process;
- group the stimulation frequencies into bands of a psychoacoustic scale;
- generate the acoustic stimulus, the acoustic stimulus comprising a masked bandpass component within each band of the psychoacoustic scale that comprises one or more of the stimulation frequencies.
