新技術：機場安檢不看指紋竟掃描耳朵

　　You"ve heard of finger printing, passport photos and eyerecognition - but the latest airport security measures could see yourEARS being scanned to prove your identity. Researchers have discoveredthat every person has uniquely-shaped ears and have formulated a way toscan them to compare them with images already compiled in a database。

　　身份識別的方式讓您眼花繚亂，什麼指紋識別、護照照片識別、眼睛識別等等，但是最新的機場安檢身份識別的手段還是會讓您「大跌眼鏡」，「耳朵」有望替代「指紋」成為另外一種身份鑒定方式在機場得到應用。專家分析，因人的「耳朵」具有獨一無二的特性，研究人緣根據「因人而異的耳朵」發明了一套掃描系統來進行身份識別。

　　This latest idea in biometrics could supplement other securitytechniques like iris scanning already being employed to combat thethreat of terrorism and illegal immigration。

　　科技的發達，讓身份識別技術更新迅速，我們根據生物測定學發明了「虹膜的身份認證」來應對當今反恐的形式。

　　He explained: "There are a whole load of structures in the ear thatyou can use to get a set of measurements that are unique to anindividual. "With biometrics, a lot of the problems is what happens whenpeople get old. With facial recognition, the systems are often confusedby crows" feet and other signs of ageing. "Your ears, however, age verygracefully."The UK Passport Service has been trialling facialrecognition technology at London Stansted Airport for the past two yearsalong with retina scanning. Another problem with facial recognition isthat software can only cope with an unchanged neutral facial expressionand struggles with happy or sad faces, or even make-up。

　　研究負責人表示，面部識別技術的方式有不盡如人意的一面，也就是人隨著年紀的增長，會變老，臉上的皺紋會影響機器的識別。不僅如此，即使臉上的皺紋沒有改變多少，您在做「面部識別」的時候，表情是開心？還是難過？或者化妝與否都能影響機器的面部識別呢。然而人的耳朵就不同了，研究顯示，人的耳朵隨著年紀的變化的改變十分緩慢，也就是說，耳朵的衰老特徵表現得不明顯。這個特質就大大地方面的身份識別機器的應用呢。

　　Researchers say ear scans are as individual as fingerprints andcould be added to biometric chips in the new generation Britishpassports However, the ear scan system is apparently 99.6 per centaccurate。

　　有統計顯示，耳朵識別身份的方法能達到99.6的準確率，如此高的準確率著實令人欣喜。
