The CHBGR 2023 invites submissions of original and unpublished work, in English, with up to 6 pages including results, figures, and references (overlength submissions will not be reviewed). Accepted papers should be presented by one of the authors as a condition for publication. Topics of interest include, but are not limited to: 

• Hard hand biometrics: hand geometry, finger knuckle, fingernail, fingerprint photo, palmprint, palm vein, finger vein

• Soft hand biometrics: hand expression, signature, keystroke dynamics

• Multi-biometrics

• Cross-domain recognition: fingerprint photo vs contact-based fingerprint 

• Person identification and re-identification

• EMG-based hand gesture recognition

• mm-wave radar-based hand gesture recognition

• Hand gesture-based interaction: cross-sensor, cross-modality

• 3D Hand pose estimation

• 3D analysis and hand biometric synthesis: adversarial learning, diffusion models

• Presentation attacks and detection

• Ethics and fairness issues

• Applications: Forensics, social robotics, HCI, healthcare, smart city, and transportation

• Databases, benchmarking and new protocols, robustness analysis.
