本文将重点介绍近几年涌现出来的三项新兴技术：手部静脉识别、人耳识别和指关节纹识别。-This article will focus on the three emerged in recent years, emerging technologies: hand vein recognition, ear recognition, and knuckle pattern recognition.

基于指纹和手背静脉的双模态生物识别系统研究，很经典的论文-Based on fingerprint and hand vein multimode biological recognition system research, it was a classic papers
