摘要信息化时代的浪潮使信息的安全性和保密性再次回归人们的视野，人体丰富的身体特征和行为特征使生物识别技术成为未来个体身份验证识别的一种有效手段。相较于传统的生物识别技术而言（指纹、虹膜、人脸、语音、步态等），手指静脉识别技术以其活体识别、内部特征、非接触式、安全等级高等诸多优点，被认定为最具潜力的生物识别技术之一，具有广阔的应用市场并具有极高的研究价值。本文就手指静脉识别技术展开讨论，分别针对图像采集、数据库构建、图像预处理、指静脉特征提取、特征分类识别五部分进行研究，给出了手指静脉识别技术研究的完整思路，并成功构建出一个大规模、系统性强、公开的多源手指静脉数据库，提出一种适用于自建数据库的ROI提取方法，为解决海量数据库的实时搜索认证提供数据基础和技术支持。89209

In this era of information and technology, people pay much more attention to the safety and security of information。 Human’s abundant biometric traits make them prevalent to be used as a way for identification and verification。 In comparison with the traditional biometrics, finger vein, as the intrinsic attributes of inpiduals, shows strong stability, non-contact characteristic as well as anti-falsification property, and it can only be detected and extracted in living bodies。 As a result, finger vein recognition is widely accepted as a biometric way with most potentials, wide application market and extremely high value of research。 In this essay, we discuss the finger vein technology in following aspects: acquisition, database construction, preprocessing, feature extraction as well as matching and classification of the finger vein images, showing the overall idea of the research。 We also successfully established a large, systematic and open source finger-vein database。 Besides, an adaptive ROI extraction method was worked out。 The work we do provides data and technical support for the real-time search and authentication with huge amount of database。
