1. A non-transitory machine-readable storage medium comprising stored instructions, which when executed by one or more processors, cause the one or more processors to:
receive a unique identifier of a tagged physical good;
receive a public key stored in a Non-Fungible Token (NFT) corresponding to the unique identifier;
encrypt a first passphrase using the public key to obtain an encrypted passphrase;
compare a second passphrase to the first passphrase, the second passphrase being generated by decrypting the encrypted passphrase using a private key stored on an electronic tag device embedded in the tagged physical good; and
generate an output indication in response to comparing the second passphrase to the first passphrase.
