集成制造技術(shù)使得我們能夠制造相稱小的指紋圖像讀取設(shè)備，同時飛速發(fā)展的個人計算機(jī)運(yùn)算速度提供了在微機(jī)甚至單片機(jī)上能夠進(jìn)行兩個指紋的比對運(yùn)算的可能。另外，匹配算法可靠性也不停提高，指紋識別技術(shù)己非常實(shí)用。1.1指紋識別介紹1.1.1指紋識別原理指紋識別技術(shù)的原理和其它生物識別技術(shù)的原理相似。它是運(yùn)用人體的指紋特性對個體身份進(jìn)行分辨和鑒定。在全部的生物識別技術(shù)中指紋識別技術(shù)是現(xiàn)在最為成熟，也被應(yīng)用最廣的生物識別技術(shù)。這重要由于指紋采用的過程對人們來講非常簡樸，指紋識別的精確率高的因素。嚴(yán)格來講，指紋識別的原理涉及指紋采集原理、指紋特性提取原理和指紋特性匹配原理三大部分。指紋采集原理重要是根據(jù)指紋的幾何特性或生理特性，通過多個傳感技術(shù)把指紋體現(xiàn)出來，形成數(shù)字化表達(dá)的指紋圖案。由于指紋的嵴和峪的幾何特性不同，重要體現(xiàn)為嵴是突起的，峪是凹下的，因此在接觸到光線時，其反射光的強(qiáng)度也就不同。在接觸到平面時，其在平面上形成的壓力也就不同。另首先，由于指紋的嵴和峪的生理特性不同，重要體現(xiàn)為：嵴和峪的溫度不同，其導(dǎo)電性也不同，其對波長的反饋也就不同。通過這些幾何的、生理的特性的不同，把人的指紋采集到計算機(jī)系統(tǒng)中形成指紋圖像。指紋特性分析的原理是對指紋圖案的整體特性和細(xì)節(jié)特性進(jìn)行提取、鑒別的原理。其分析的對象涉及紋形特性和特性點(diǎn)的分布、類型，以及一組或多組特性點(diǎn)之間的平面幾何關(guān)系。特性點(diǎn)的平面幾何關(guān)系體現(xiàn)為某個特性點(diǎn)之間的距離等，或者某
