  In this paper, we introduce a learning model able to conceals personal
information (e.g. gender, age, ethnicity, etc.) from an image, while
maintaining any additional information present in the image (e.g. smile,
hair-style, brightness). Our trained model is not provided the information that
it is concealing, and does not try learning it either. Namely, we created a
variational autoencoder (VAE) model that is trained on a dataset including
labels of the information one would like to conceal (e.g. gender, ethnicity,
age). These labels are directly added to the VAE's sampled latent vector. Due
to the limited number of neurons in the latent vector and its appended noise,
the VAE avoids learning any relation between the given images and the given
labels, as those are given directly. Therefore, the encoded image lacks any of
the information one wishes to conceal. The encoding may be decoded back into an
image according to any provided properties (e.g. a 40 year old woman).
  The proposed architecture can be used as a mean for privacy preserving and
can serve as an input to systems, which will become unbiased and not suffer
from prejudice. We believe that privacy and discrimination are two of the most
important aspects in which the community should try and develop methods to
prevent misuse of technological advances.
