Abstract

A new symbology designed around morphometrics and well-adapted to object authentication is introduced. Morphometrics are defined in a formal way as the output of a new channel (the scan-only channel) working in parallel to the classical print/scan channel. Two protocols based on cryptographic schemes are presented for a visual verification. A variant of the secret sharing scheme is suggested for one of them.
