基于手指血管圖像識別的身份認(rèn)證終端

        身份認(rèn)證技術(shù)是維持現(xiàn)代社會運行的一項重要技術(shù)，目前常用的認(rèn)證技術(shù) 如密碼、指紋、簽名等存在容易遺忘和偽造的缺點，因而需要加以改進(jìn)。 

        我們利用手指血管圖像識別這一新型的生物特征識別技術(shù)，通過自制手指 血管圖像采集裝置，實現(xiàn)了模塊化、多用途的基于手指血管圖像識別的身份識 別終端。我們在終端上加上磁卡讀卡器、屏幕、票據(jù)打印機(jī)等外設(shè)，制作了以 手指血管圖像為密鑰的POS 機(jī)。 用該終端實現(xiàn)的POS 機(jī)具有以下功能：
1. 讀取銀行借記卡、貸記卡中的卡號等信息
2. 通過手指血管圖像識別驗證用戶身份
3. 輸入消費金額并打印憑條
4. 通過網(wǎng)絡(luò)與遠(yuǎn)程數(shù)據(jù)庫交換數(shù)據(jù)
5. 新用戶的注冊功能

The modern society features the authentication technology. The main authentication technology such as password, fingerprint and signature has the disadvantages of easy to being forgotten and forged, so it should be improved. In this paper, we provide a modularized and multipurpose authentication terminal based on the finger vein pattern recognition, which contains a finger vein camera 500 designed by ourselves. The equal error rate (EER) of the recognition is 2.11%, and the recognition time is less than 1s. We add peripherals such as magnetic card reader, the notes printer and the screen to the authentication terminal to realize the function of POS. 

The POS implemented by this terminal have the following functions.
1. Read information from magnetic cards.
2. Authentication via finger vein pattern recognition.
3. Input of spend and prints of information related.
4. The exchange of data via network with remote database.
5. New user registration.
