DIF-V: A Diverse, Inclusive Synthetic Face Dataset for Fairer Verification

Face checks power everything from phone unlocks to banking logins — but training data often skews toward certain races and genders. This paper presents a method to generate high-quality, ID‑photo‑style synthetic faces that better reflect real‑world diversity, and introduces a new benchmark: Diverse and Inclusive Faces for Verification (DIF‑V).

  • DIF‑V includes 27,780 images across 926 identities for fairer evaluation.
  • Popular verification models still favor some genders and races.
  • Applying identity style changes reduces verification accuracy.
  • Generation rules enforce ID‑photo standards (lighting, pose, background).

The aim: more inclusive, transparent, and reliable face verification — with fewer privacy risks than using real faces. Learn more: https://arxiv.org/abs/2511.17393v1
