Not with my name! Inferring artists' names of input strings employed by
  Diffusion Models

Diffusion Models (DM) are highly effective at generating realistic,
high-quality images. However, these models lack creativity and merely compose
outputs based on their training data, guided by a textual input provided at
creation time. Is it acceptable to generate images reminiscent of an artist,
employing his name as input? This imply that if the DM is able to replicate an
artist's work then it was trained on some or all of his artworks thus violating
copyright. In this paper, a preliminary study to infer the probability of use
of an artist's name in the input string of a generated image is presented. To
this aim we focused only on images generated by the famous DALL-E 2 and
collected images (both original and generated) of five renowned artists.
Finally, a dedicated Siamese Neural Network was employed to have a first kind
of probability. Experimental results demonstrate that our approach is an
optimal starting point and can be employed as a prior for predicting a complete
input string of an investigated image. Dataset and code are available at:
