Copyright Protection of 3D Digitized Artistic Sculptures by Adding Unique Local Inconspicuous Errors by Sculptors

In recent years, digitization of cultural heritage objects, for the purpose creating virtual museums, is becoming increasingly popular. Moreover, institutions use modern methods to create three-dimensional (3D) models objects historical significance form digital libraries and archives. This research aims suggest a method protecting these 3D from abuse while making them available on Internet. The proposed was applied sculpture, an object heritage. It based sculpture altered by adding local clay details sculptor sharing Internet model obtained digitizing with built-in error. embedded in are asymmetrical discreet be unnoticeable average observer. original also digitized its created. were compared geometry deviation measured determine that error invisible observer watermark can extracted. simultaneously protects image artwork preserving visual experience.
