Technical Overview

Augmented authentication software

– Image data is scanned through camera hardware with a minimum of 12 megapixels
– This is then converted into an artwork’s ID, using the (fully developed) “augmented authentication” technology licensed to 4ARTechnologies by industry leader Atlantic Zeiser GmbH
– Micro-level image data is encoded and stored on the blockchain network
– Beyond the initial check, the software draws on this data for subsequent image

authentication checks and condition reports

Blockchain service
– 4ARTechnologies utilizes the Ethereum block-
chain; its smart contract functionality guarantees validation of all transactions as well as data immutability
– Any modification or transaction concerning the artwork – either the material image, e.g. through restoration, or its status, e.g. sales or loans – will be registered in the 4ART Digital Artwork Catalog with its unique systems ID (ArtID)
– The data submitted to the blockchain, i.e. the
fingerprint and data set, amounts to roughly 160 kilobytes

Cloud service

– 4ARTechnologies’ cloud service hosts the data
from which an artwork’s fingerprint is generated
– Equipped with a user friendly interface, the cloud service provides access to an image’s complete data set and other services around the image’s entire life cycle
– Any data set that is stored in the cloud service
also has a corresponding blockchain fingerprint, thus guaranteeing authenticity of cloud data

SYSTEM & TECHNOLOGY

Access and security
– The 4ART Digital Artwork Catalog is accessible
through the desktop web application
– User roles make sure that features and functionalities are only available to appropriate parties
– All users who are able to generate an artwork’s fingerprint and “biometrical passport”, or make changes to this passport (e.g. restorers), are verified according to KYC-technology in line with Swiss regulatory requirements for banks
– User profiles are encrypted and stored on the cloud
– All privacy requirements are respected at all
times. The solution is fully GDPR compliant
Payment and tokens
– All services can be obtained by redeeming the
4ART utility tokens. The 4ART utility tokens can in turn be acquired through a variety of means, such as payment via FIAT currencies, credit or debit cards, or cryptocurrencies such as the 4ART payment tokens.
