Abstract
A cavity authentication system for verifying at least one feature of a user using at least one acoustic signal, including an orifice element, including at least a signal opening and a reflection opening, an acoustic wave generator (AWG), an acoustic wave sensor (AWS), at least one output waveguide, at least one input waveguide, a processor, a memory and a power supply, the AWG for producing at least one acoustic signal, the AWS for receiving at least one reflection of the acoustic signal, the output waveguide for transmitting the acoustic signal to the user, the input waveguide for receiving the reflection of the acoustic signal, the memory configured to store cavity authentication data representative of the feature, wherein the processor is configured to analyze the reflection and to compare the analyzed reflection with the retrievable cavity authentication data and to generate an indication whether the analyzed reflection matches the retrievable cavity authentication data above a pre-determined threshold.
