Abstract
A method for authenticating a timepiece including measuring acoustic vibrations emitted by said timepiece to obtain an electrical signal, said electrical signal indicating a variation of a magnitude of said measured acoustic vibrations as a function of time, wherein said electrical signal comprises a plurality of acoustic events associated with mechanical shocks taking place in said timepiece, extracting from said electrical signal or from a representation of said electrical signal in a time, frequency or time-frequency domain at least one of a magnitude information on a magnitude of one of said plurality of acoustic events, time information on said one of said plurality of acoustic events, and a frequency information on a frequency of said one of said plurality of acoustic events, comparing said extracted information with at least one of a reference information, and deriving information on an authenticity of said timepiece based on the comparing.
