Abstract
Method for authenticating a timepiece including applying at least one external excitation to said timepiece using an external device, measuring acoustic vibrations at least one of emitted and absorbed inside the timepiece to obtain an electrical signal representative of the measured acoustic vibrations, wherein a magnitude of the electrical signal represents magnitude information of the measured acoustic vibrations as a function of time, comparing the magnitude information with at least one reference magnitude information, and determining an authenticity of the timepiece based on the comparing.
Claims31
A method for authenticating a timepiece comprising:
- applying at least one external excitation to said timepiece using an external device;
- measuring acoustic vibrations at least one of emitted and absorbed inside the timepiece to obtain an electrical signal representative of the measured acoustic vibrations, wherein a magnitude of the electrical signal represents magnitude information of the measured acoustic vibrations as a function of time;
- comparing the magnitude information with at least one reference magnitude information;
- and
- determining the authenticity of said timepiece based on the comparing.
A system for authenticating a timepiece comprising:
- an exciter for applying at least one external excitation to said timepiece using an external device
- a detector for measuring acoustic vibrations at least one of emitted and absorbed inside the timepiece to obtain an electrical signal representative of the measured acoustic vibrations, wherein a magnitude of the electrical signal represents magnitude information of the measured acoustic vibrations as a function of time;
- a comparator for comparing the magnitude information with at least one reference magnitude information;
- and
- an authenticator for determining an authenticity of said timepiece based on the comparing.
A method for creating an identifier for a timepiece comprising:
- applying at least one external excitation to the timepiece using an external device;
- measuring acoustic vibrations at least one of emitted and absorbed inside the timepiece to obtain an electrical signal representative of the measured acoustic vibrations;
- and
- creating an identification code based on the electrical signal using a processor of a computing device.
