Description
本发明涉及一种基于掌静脉识别技术的支付系统的方案，属于第三代生物识别技术领域。
现有技术中，大多数采用的是卡式管理，比较先进的采用的是生物技术进行验证管理，而掌静脉识别生物技术在这个领域刚刚发展。掌静脉识别是静脉识别的一种，属于生物识别，掌静脉识别系统就是首先通过静脉识别仪取得个人掌静脉分布图，从掌静脉分布图依据专用比对算法提取特征值，通过红外线CCD摄像头获取手掌、手背静脉的图像，将静脉的数字图像存贮在计算机系统中，将特征值存储。静脉比对时，实时采取静脉图，提取特征值，运用先进的滤波、图像二值化、细化手段对数字图像提取特征，同存储在主机中静脉特征值比对，采用复杂的匹配算法对静脉特征进行匹配，从而对个人进行身份鉴定，确认身份。
用掌静脉进行身份认证时，获取的是掌静脉的图像特征，是指活体时才存在的特征。在该系统中，非活体的手掌是得不到静脉图像特征的，因而无法识别，从而也就无法造假。用掌静脉进行身份认证时，获取的是手掌内部的静脉图像特征，而不是手掌表面的图像特征。因此，不存在任何由于手掌表面的损伤、磨损、干燥或太湿等带来的识别障碍。用掌静脉进行身份认证，获取手掌静脉图像时，手掌无须与设备接触，轻轻一放，即可完成识别。这种方式没有手接触设备时的不卫生的问题以及手掌表面特征可能被复制所带来的安全问题，并避免了被当作审查对象的心理不适，同时也不会因脏物污染后无法识别。手掌静脉方式由于静脉位于手掌内部，气温等外部因素的影响程度可以忽略不计，几乎适用于所有用户。用户接受度好。除了无需与扫描器表面发生直接接触以外，这种非侵入性的扫描过程既简单又自然，减轻了用户由于担心卫生程度或使用麻烦而可能存在的抗拒心理。因为有了前面的活体识别、内部特征和非接触式3个方面的特征，确保了使用者的掌静脉特征很难被伪造。所以掌静脉识别系统安全等级高，特别适合于安全要求高的场所使用。但是现有技术中还存在以下问题待解决：(1)属于内生理特征，不会磨损，较难伪造，具有很高安全性。(2)血管特征通常更明显，容易辨识，抗干扰性好。(3)可实现非接触式测量，卫生性好，易于为用户接受。(4)不易受手表面伤痕或油污的影响。以上技术存在的缺点是：采集设备有特殊要求，设计相对复杂，制造成本高。
随着电子技术的快速发展，各种各样的智能设备进入到人们的日常生活当中，以往，人们在外消费时都是采用现金付费方式，然而现在，人们出门消费一般多数都采用刷卡方式，尤其
是对于大数目金额的消费，这种刷卡付账方式使人们不用携带大量的现金出门，保证了人们的财产安全，但是，伴随刷卡付账方式带来的问题也日益凸显出来，最为突出的一点就是人们需要办理各种各样的银行卡、信用卡等，人们对各种各样银行卡和信用卡的管理方式为集体管理，即将所有的卡放置在一个卡包或钱包里，若卡包或钱包不慎遗失，将会给人们带来很大麻烦和不便。
