"Overt" authentication features include holograms and, more often, opti- cal variable devices (OVDs), variable inks or films, watermarks, secure printing methods, etc. These devices reveal a unique feature when manipulated (con- cealed image, irisation, embossing, etc.). They are intended to be evaluated by in- dividuals with at least minimum knowl- edge of what needs to be checked. By definition, the inspector does not use spe- cific or "intelligent" tools for this inspec- tion. Most of these technologies can be used on existing or specific wine labels. For an unsuspecting public, imitation of these features can easily deceive and give false assurance about the identity of the product. Their cost is highly variable. Near-field communication (NFC) technol- ogy can also be used with overt features (e.g. hologram stickers) and enable the accessible product to be authenticated using a mobile device. The NFC further permits a simple authentication to be vali- dated by the end user, with virtually no risk of error of interpretation. CovErT (CoDED or hiDDEn) fEaTurES Technologies provided with covert features are characterized by the need for an expert scanning system, as these technologies cannot be read with the naked eye. The inspector must have the right tool to provide verification (em- bedded or remote software), and he must be trained how to use the tool. "Covert" authentication features include hidden or coded imprints, digital mark- ings, taggants (nanoparticles), added mate- rials (chaos), radio-frequency identification (RFID) and certain intrinsic properties of the product material or its packaging. mercadercorkusa.com info@mercadercorkusa.com T.
