Artifact Imaging offers services to secure artworks. This part of our activity involves storing data in the Blockchain. This operation makes the data usable for traceability purposes, but also for a spot check on a piece of art previously digitized by us. It is thus possible to establish for any artifact included in our database a three-dimensional condition report, thanks to a model that can be measured to the nearest micron, that is unalterable, incorruptible, searchable at will and remotely, and that brings together all the associated metadata.
