Abstract
This disclosure describes techniques to affix an embossed pattern on an object such that when the pattern is scratched over by a hard object such a coin, pencil, or fingernail, a distinctive sonic signature is emitted. The sonic signature can be used, e.g., by a virtual assistant application, a smart speaker, or other device, to identify the object.
