Ge\u00e7ti\u011fimiz g\u00fcnlerde, Japonya\u2019n\u0131n \u00e7e\u015fitli \u00fcniversitelerinden bir araya gelen bir grup ara\u015ft\u0131rmac\u0131, daha \u00f6nce g\u00f6r\u00fclmemi\u015f bir biyometrik kimlik do\u011frulama y\u00f6ntemini a\u00e7\u0131klayan ilgin\u00e7 bir ara\u015ft\u0131rma<\/a> ortaya koydu: nefes analizi. Ortaya \u00e7\u0131kan fikir, sizin ve benim gibi s\u0131radan s\u00fcr\u00fcc\u00fclerin bazen, profesyonel s\u00fcr\u00fcc\u00fclerin ve di\u011fer tehlikeli i\u015flerde \u00e7al\u0131\u015fan ki\u015filerin ise d\u00fczenli olarak tabi tutulduklar\u0131 nefes alkol testlerine benziyor.<\/p>\n

Fakat, tek ortak \u00f6zellik bu. Ara\u015ft\u0131rmada ileri s\u00fcr\u00fclen y\u00f6ntem daha da karma\u015f\u0131k. \u00d6ncelikle, y\u00f6ntemin sadece bir de\u011fil, nefeste bulunan birka\u00e7 farkl\u0131 kimyasal bile\u015fi\u011fin neler oldu\u011funu saptamas\u0131 gerekiyor. \u00dcstelik, y\u00f6ntem sadece belirli maddelerin yo\u011funlu\u011funu tespit etmekle kalmayacak, ayn\u0131 zamanda kimyasal \u201cnefes izleri\u201d ile bir ki\u015fiyi di\u011ferinden ay\u0131rt edecek.<\/p>\n

Ama\u2026neden?<\/strong><\/h2>\n

Ara\u015ft\u0131rmac\u0131lar\u0131n \u00e7al\u0131\u015fmalar\u0131yla ilgili g\u00fczel olan detay ise, kendilerine herhangi bir ama\u00e7 belirlemek zorunda olmamalar\u0131! Yani, bunu sadece yapabildikleri i\u00e7in yap\u0131yorlar.<\/p>\n

Nihayetinde, nefes analizinin teknolojide en ileri ara\u015ft\u0131rma alan\u0131 oldu\u011fu d\u00fc\u015f\u00fcn\u00fcl\u00fcyor. Bu alanda verileri i\u015flemek i\u00e7in kullan\u0131lan makine \u00f6\u011frenimi sayesinde, solunum yolu hastal\u0131klar\u0131n\u0131n te\u015fhisi<\/a>nde \u00f6nemli geli\u015fmeler elde edildi. Madem \u00f6yle, mevcut analiz ve \u00f6\u011frenme algoritmalar\u0131 sistemleri kullan\u0131larak, neden kimlik do\u011frulama olas\u0131l\u0131\u011f\u0131 ara\u015ft\u0131r\u0131lmas\u0131n?<\/p>\n

\u0130lk a\u015famada, deneklerin soludu\u011fu hava toplan\u0131r. Daha sonra, toplanan hava 16 kanal\u0131 olan bir analiz cihaz\u0131ndan ge\u00e7irilir (ara\u015ft\u0131rmac\u0131lar daha az say\u0131da sens\u00f6r kullanarak veri toplamay\u0131 denedi, ancak y\u00f6ntemin etkinli\u011fi hemen azald\u0131).<\/p>\n

Her kanal, havada bulunan belirli bir kimyasal bile\u015fi\u011fi ayr\u0131 ayr\u0131 alg\u0131lar. Analiz cihaz\u0131, sadece sens\u00f6rlerden gelen sinyalin yo\u011funlu\u011funu de\u011fil, bu yo\u011funlu\u011fun zaman i\u00e7indeki de\u011fi\u015fimini de kaydeder.<\/p>\n

Sonu\u00e7ta, b\u00fcy\u00fck miktarda veri dizisi toplan\u0131yor ve daha sonra bir makine \u00f6\u011frenimi algoritmas\u0131 yard\u0131m\u0131yla i\u015fleniyor.

Ne kadar g\u00fcvenilir?<\/strong><\/h2>\n

Japon bilim insanlar\u0131, vakalar\u0131n %97\u2019sinde nefeslerini analiz ederek, ki\u015fileri do\u011fru bir \u015fekilde tespit edebildiler. Bu bir ba\u015far\u0131 say\u0131labilir mi? Bu ara\u015ft\u0131rma, bu soruya cevap verebilmek i\u00e7in yeterli veriye sahip de\u011fil.<\/p>\n

Genel performans\u0131, di\u011fer her \u015feyin yan\u0131 s\u0131ra biyometrik sistemlerin kapsamlar\u0131n\u0131 de\u011ferlendiren 2016 y\u0131l\u0131na ait bir \u00e7al\u0131\u015fma<\/a>da elde edilen verilerle kar\u015f\u0131la\u015ft\u0131rabiliriz.

Ancak, yukar\u0131da bahsedilen 2016 \u00e7al\u0131\u015fmas\u0131n\u0131n da vurgulad\u0131\u011f\u0131 \u00fczere, yanl\u0131\u015f negatiflerin (kay\u0131tl\u0131 kullan\u0131c\u0131lar\u0131n tan\u0131nmamas\u0131) sebep olaca\u011f\u0131 yanl\u0131\u015f pozitif (bir yabanc\u0131n\u0131n kimli\u011finin do\u011frulanmas\u0131) oran\u0131n\u0131 hesaba katmak olduk\u00e7a \u00f6nemli.

Bu y\u00fczden, onlar\u0131 ortadan kald\u0131rmak da en b\u00fcy\u00fck \u00f6ncelikler aras\u0131nda. Ancak bu ara\u015ft\u0131rmada, koku ile kimlik do\u011frulaman\u0131n, yanl\u0131\u015f pozitifler s\u00f6z konusu oldu\u011funda nas\u0131l \u00e7al\u0131\u015ft\u0131\u011f\u0131na dair yeteri kadar ayr\u0131nt\u0131l\u0131 bilgi yok.<\/p>\n

\u0130lgin\u00e7 bir dipnot d\u00fc\u015felim: Nefes analizi ara\u015ft\u0131rmac\u0131lar\u0131, makalelerinde, kendi ara\u015ft\u0131rmalar\u0131 dahil, \u00f6nceki \u00e7al\u0131\u015fmalara da at\u0131fta bulundular. \u0130nsan terinin kimyasal analiziyle kar\u015f\u0131la\u015ft\u0131rma yaparak geli\u015fmeleri not ettiler. (Evet, tere dayal\u0131 kimlik do\u011frulama da ara\u015ft\u0131rma konusu olmu\u015f!)<\/p>\n

Ne kadar kullan\u0131\u015fl\u0131?<\/strong><\/h2>\n

Ara\u015ft\u0131rmac\u0131lar, bir diz\u00fcst\u00fc bilgisayara, telefona ve hatta arabaya bile ba\u011flayamayaca\u011f\u0131n\u0131z pahal\u0131 laboratuvar ekipmanlar\u0131 kulland\u0131lar.

Ayr\u0131ca, ara\u015ft\u0131rmay\u0131 incelerken, \u00f6n\u00fcm\u00fczdeki g\u00fcnlerde ak\u0131ll\u0131 telefonlar\u0131m\u0131z\u0131n kilidini a\u00e7mak i\u00e7in neden onlara do\u011fru nefes almayaca\u011f\u0131m\u0131za dair daha \u00e7ok sebep buluyorsunuz: Yukar\u0131da da belirtildi\u011fi gibi, do\u011frulu\u011fu hesaplamak i\u00e7in, belirli kimyasal bile\u015fiklerin bozulma s\u00fcresini de (40 dakika kadar) \u00f6l\u00e7t\u00fcler.<\/p>\n

Hepsi bu kadarla da s\u0131n\u0131rl\u0131 kalm\u0131yor: Deneklerin, deneyden alt\u0131 saat \u00f6ncesine kadar yemek yemelerine izin verilmedi. Ara\u015ft\u0131rmac\u0131lar, sonu\u00e7lar\u0131n do\u011frulu\u011funun, k\u0131sa s\u00fcre \u00f6nce yenen bir ak\u015fam yeme\u011finden veya \u00e7e\u015fitli hastal\u0131klar sebebiyle nefeste bulunan bile\u015fiklerden etkilenebilece\u011fini belirtiyor. G\u00f6r\u00fcnen o ki, hafif alkol kokusu ya da basit bir so\u011fuk alg\u0131nl\u0131\u011f\u0131 test sonu\u00e7lar\u0131n\u0131 etkileyebilir.<\/p>\n
