- 有浏览器插件。一般由指纹识传感器厂商提供,如: https://helpdesk.lastpass.com/security-options/multifactor-authentication-options/fingerprint/
- 如果你要做Server端的认证,Browser端只收集指纹信息,那么指纹确实是以图片的形式发给服务器端的,其过程就像你写博客的时候上传一张附图一样。如: http://plurilock.com/products/fingerpass
- 指纹识别其实是一个典型的计算机图像处理任务,OpenCV就是干这个的,原理参见: http://answers.opencv.org/question/6364/fingerprint-matching-in-mobile-devices-android/#6370 ,OpenCV有Python版SDK: http://docs.opencv.org/trunk/doc/py_tutorials/py_tutorials.html
