Face recognition technology has made remarkable progress, but it still faces several critical challenges. Here's a breakdown of the key issues:

1. Data Diversity

  • 🧍‍♂️ Race, Gender, and Age Bias: Most datasets are skewed toward specific demographics, leading to poor performance on underrepresented groups.
  • 🌍 Cultural Variations: Facial features vary globally, requiring diverse training data to avoid cultural misinterpretations.
  • 📊 Distribution Imbalance: Underrepresented ethnicities or age groups can cause significant accuracy drops.

2. Environmental Factors

  • 🔍 Lighting Conditions: Low light, glare, or shadows can distort facial features.
  • 📷 Angle and Pose: Extreme angles or head movements reduce recognition reliability.
  • 🌤️ Weather and Occlusion: Rain, masks, or accessories may obscure key facial landmarks.

3. Privacy and Ethics

  • ⚠️ Data Security Risks: Biometric data is sensitive and requires strict protection.
  • 🧾 Consent Issues: Unauthorized use of facial data raises ethical concerns.
  • 🌐 Surveillance Concerns: Mass deployment may infringe on personal privacy rights.
