識(shí)別技術(shù)和筆跡識(shí)別技術(shù)等。生物識(shí)別技術(shù)的優(yōu)勢(shì)主要有：1、減少、消除身份假冒，進(jìn)展真實(shí)身份確實(shí)認(rèn)；2、降低管理本錢，取代了身份人工認(rèn)證過程；3、方便使用者，減少或消除了使用卡、鑰匙或者密碼等麻煩。生物識(shí)別技術(shù)的開展主要起始于指紋研究，它亦是目前應(yīng)用最為廣泛的生物識(shí)別技術(shù)。指紋識(shí)別技術(shù)的開展得益于現(xiàn)代電子集成制造技術(shù)和快速可靠的算法的研究。盡管指紋只是人體皮膚的小局部，但用于識(shí)別的數(shù)據(jù)量相當(dāng)大，對(duì)這些數(shù)據(jù)進(jìn)展比對(duì)也不是簡(jiǎn)單的相等與不相等的問題，而是使用需要進(jìn)展大量運(yùn)算的模糊匹配算法?，F(xiàn)代電子集成制造技術(shù)使得我們可以制造相當(dāng)小的指紋圖像讀取設(shè)備，同時(shí)飛速開展的個(gè)人計(jì)算機(jī)運(yùn)算速度提供了在微機(jī)甚至單片機(jī)上可以進(jìn)展兩個(gè)指紋的比對(duì)運(yùn)算的可能。另外，匹配算法可靠性也不斷提高，指紋識(shí)別技術(shù)己非常實(shí)用。1.1指紋識(shí)別簡(jiǎn)介1.1.1指紋識(shí)別原理指紋識(shí)別技術(shù)的原理和其它生物識(shí)別技術(shù)的原理相似。它是利用人體的指紋特征對(duì)個(gè)體身份進(jìn)展區(qū)分和鑒定。在所有的生物識(shí)別技術(shù)中指紋識(shí)別技術(shù)是目前最為成熟，也被應(yīng)用最廣的生物識(shí)別技術(shù)。這主要因?yàn)橹讣y采用的過程對(duì)人們來(lái)講非常簡(jiǎn)單，指紋識(shí)別的準(zhǔn)確率高的原因。嚴(yán)格來(lái)講，指紋識(shí)別的原理包括指紋采集原理、指紋特征提取原理和指紋特征匹配原理三大局部。指紋采集原理主要是根據(jù)指紋的幾何特性或生理特性，通過各種傳感技術(shù)把指紋表現(xiàn)出來(lái)，形成數(shù)字化表示的指紋圖案。由于指紋的嵴和峪的幾何特征不同，主要表現(xiàn)為嵴是突起的，峪是凹下的，所以在接觸到光線時(shí)，其反射光的強(qiáng)度也就不同。在接觸到平面時(shí)，其在平面上形成的壓力也就不同。另一方面，由于指紋的嵴和峪的生理特征不同，主要表現(xiàn)為：嵴和峪的溫度不同，其導(dǎo)電性也不同，其對(duì)波長(zhǎng)的反響也就不同。通過這些幾何的、生理的特性的不同，把人的指紋采集到計(jì)算機(jī)系統(tǒng)中形成指紋圖像。指紋特征分析的原理是對(duì)指紋圖案的整體特征和細(xì)節(jié)特征進(jìn)展提取、鑒別的原理。其分析的對(duì)象包括紋形特征和特征點(diǎn)的分布、類型，以及一組或多組特征點(diǎn)之間的平面幾何關(guān)系。特征點(diǎn)的平面幾何關(guān)系表現(xiàn)為*個(gè)特征點(diǎn)之間的距
