如何在Oracle中匹配指纹? [英] How to match finger prints in Oracle?

问题描述

我有一个要更改的应用程序，以便通过用户的指纹验证用户.基本上，登录窗口将被重新设计为丢失登录名和密码字段.在他们的位置，窗口将等待，直到有人将他/她的手指放在连接到工作站的指纹扫描仪上.

I have an application that is about to change in order to validate users by their finger prints. Basically, the logon window will be redesigned to lose the login name and password fields. In their place, the window will wait until someone puts his/her finger on a fingerprint scanner connected to the workstation.

由于大约有50,000个用户，其帐户数据存储在Oracle服务器中，所以问题在于要保存在User表中的内容以及如何通过使用指纹数据而不是登录名/密码对来选择正确的用户?

Since there are about 50,000 users, whose account data are stored in a Oracle server, the problem is what to save in the User table and how to select the correct user by using the fingerprint data instead the login name/password pair?

推荐答案

匹配指纹模板(或图像)不仅仅是字节数组的比较.请阅读以下内容: https://en.wikipedia.org/wiki/Fingerprint_recognition

Matching fingerprint template (or image) is not just a compare of byte array. Please read this: https://en.wikipedia.org/wiki/Fingerprint_recognition

要匹配50,000个用户(每个用户要注册多少个手指)，您需要 AFIS

To match 50,000 users (How many finger are enrolled for each user) you need an AFIS

AFIS提供者很多，例如:

There's a lot of AFIS provider as:
