Abstract: A method and system for creating and storing an identifier for a timepiece having at least one gemstone. The method includes determining one or more characteristics of the at least one gemstone and detecting a relative position of the at least one gemstone in the timepiece. The method further includes creating the identifier for the timepiece in dependence upon at least one of the one or more characteristics of the at least one gemstone and the respective relative position of the at least one gemstone and storing the identifier in a database or device.

Abstract: A method of authenticating a product by taking an image of the product and comparing the image with a reference image of a genuine product taken previously to determine if the products in the two images are the same. The two images are captured under substantially similar conditions so that the two images are as similar as possible prior to the comparison. The two images are processed in order to calculate for each of them a list of significant points. The significant points are compared to determine a degree of correspondence between the significant points. An answer is output indicating the authenticity of the product based on the degree of correspondence. Some of the matching significant points may be used to define a common coordinate system for the two images. The two lists of significant points may be compared in this common coordinate system.

Abstract: Embodiments relate to method for authenticating timepiece comprising measuring acoustic vibrations emitted by timepiece to obtain electrical signal, which indicates variation of magnitude of measured acoustic vibrations as function of time. The method includes processing electrical signal to attenuate plurality of acoustic events in said electrical signal, performing transform of processed electrical signal into a frequency domain to obtain frequency-domain power spectrum indicating variation of power of processed electrical signal as a function of frequency, identifying at least one narrow peak in frequency-domain power spectrum corresponding to at least one resonance frequency of a part of timepiece resonating in a quiet zone. The method also includes extracting at least one resonance frequency corresponding to at least one narrow peak, comparing extracted at least one resonance frequency with at least one reference resonance frequency, and deriving information on an authenticity of said timepiece based on the comparing.
