IDCERT.ART is an independent certification system to guarantee the origin and authenticity of works of art. The works are labeled with a secure hologram sticker, upon application of this label a certificate is prepared with a copy of the unique numbered hologram sticker. The owner of the work can claim ownership here by entering the number. With this action, he will receive a unique code. When selling the work this code can be passed on to the new owner so that he can generate his own unique and anonymous ownership code.
