【正文】 原來執(zhí)法機(jī)構(gòu)使用的指紋識(shí)別方式僅存儲(chǔ)指紋上一些特定點(diǎn)的數(shù)據(jù)而非整個(gè)影像，因而相比之下，生物指紋掃描系統(tǒng)更為有效、可靠。此人則將其右手的第一、二或第三個(gè)手指置于一個(gè)與無線 PDA 相連的傳感器上，可以迅速將嫌疑人與以前的犯罪記錄進(jìn)行對(duì)比確認(rèn)。這種軟件采集原始的指紋圖像，將圖像信息數(shù)字化并提取其中的細(xì)節(jié)模板，然后進(jìn)行測(cè)試，確定提取的細(xì)節(jié)模板是否與參考模板吻合 。 The registration authentication procedure hits the mark from a fingerprint 30~40 characteristic withdraws seven characteristics matches spot to carry on the confirmation at least, including constitutes some fingerprint detail the trace bifurcation and the end point, and is defined the characteristic point the distance. When carries on the registration, the information code is saved, will take the next user authentication the reference template. When the user enters the system, he/She has delimited the finger the sensor region, gains the scene scanning template and the reference template carry on the parison. The entire process pletes in 1 or 2 seconds. Through the parison, the system can determine whether this scene scanning template has contained the enough biological data which tallies with the reference template, and judgment two whether do match. If does not match, then the authentication defeat, waited for the next time will distinguish. This kind of fingerprint examination system performance is very high, makes the wrong judgment to the effective fingerprint the probability to be smaller than 1%, but invalid fingerprint for effective fingerprint possibility then does not exist nearly, its probability is lower than %. 新型指紋識(shí)別傳感器的應(yīng)用分析 摘 要 指紋識(shí)別技術(shù)作為一種先進(jìn)的身份識(shí)別方法，已經(jīng)被廣泛使用于各行各業(yè)中。這兩類指紋傳感器將得到越來越廣泛的應(yīng)用。不久的將來還將逐漸用于汽車單觸式無鑰匙進(jìn)入系統(tǒng)，以及新興的國(guó)家安全應(yīng)用中。 在語(yǔ)音郵件的應(yīng)用中，當(dāng)撥出一個(gè)語(yǔ)音郵件號(hào)碼后，用戶只需將手指劃過傳感器便可令系統(tǒng)識(shí)別。 通過比較，系統(tǒng)會(huì)確定這一現(xiàn)場(chǎng)掃描模板是否包含了與參考模板相符的足夠生物數(shù)據(jù)，并判斷二者是否匹配。指紋模板和匹配軟件保存在汽車內(nèi)的一個(gè)嵌入式模塊中。劃擦型傳感器的優(yōu)點(diǎn)是尺寸小 (如富士通的MBF300尺寸僅為 mm2)和成本低。 人類的指紋由緊密相鄰的凹凸紋路構(gòu)成，通過對(duì)每個(gè)像素點(diǎn)上利用標(biāo)準(zhǔn)參考放電電流，便可檢測(cè)到指紋的紋路狀況。 4050 字?jǐn)?shù) 外文翻譯 New fingerprint identification sensor applications analysis Abdtract Fingerprint recognition technology as a sophisticated identification methods have been widely used in various industries.
