Kiral\u0131k dairelerde veya otel odalar\u0131ndaki gizli kameralar: Ger\u00e7ek mi, kurgu mu? Ger\u00e7ek, ne yaz\u0131k ki. Olduk\u00e7a yeni bir vakada, \u0130rlanda\u2019da bir daire kiralayan Yeni Zelandal\u0131 bir aile, oturma odas\u0131ndan canl\u0131 yay\u0131n yapan gizli bir kamera ke\u015ffetti.<\/a><\/p>\n

\u00c7\u0131plak g\u00f6zle bir kameray\u0131 tespit etmek i\u00e7in X-ray g\u00f6r\u00fc\u015f\u00fc gerekir, \u00e7\u00fcnk\u00fc \u00e7o\u011funlukla \u00f6zenle kamufle edilmi\u015f olurlar. Superman olmayan bizler i\u00e7in ise elektromanyetik radyasyon veya Wi-Fi sinyali ile casus cihazlar\u0131 tespit etmeye yard\u0131mc\u0131 olan \u00f6zel cihazlar var, ancak bunlar standart seyahat e\u015fyalar\u0131 de\u011fil. \u00dcstelik bunlardan en iyi \u015fekilde yararlanmak i\u00e7in \u00f6zel becerilere veya uzman yard\u0131m\u0131na ihtiyac\u0131n\u0131z var.<\/p>\n

Bununla birlikte, Singapur\u2019daki ara\u015ft\u0131rmac\u0131lar k\u0131sa s\u00fcre \u00f6nce normal bir ak\u0131ll\u0131 telefonun i\u00e7indeki ToF sens\u00f6r\u00fcn\u00fc kullanarak gizli bir cihaz\u0131 bulmak i\u00e7in bir \u00e7\u00f6z\u00fcm geli\u015ftirdiler. Bu yeni y\u00f6ntem LAPD<\/a> (Lazer Destekli Foto\u011fraf Tespiti) ad\u0131n\u0131 ta\u015f\u0131yor.<\/p>\n

ToF sens\u00f6r\u00fc nedir?<\/h2>\n

\u201cToF sens\u00f6r\u00fc\u201d ve \u201cToF kamera\u201d terimleri sizin i\u00e7in hi\u00e7bir \u015fey ifade etmese bile, ak\u0131ll\u0131 telefonunuzda bu teknolojiyle kar\u015f\u0131la\u015fm\u0131\u015f olabilirsiniz. \u00d6rne\u011fin, ekran kilidini y\u00fczle a\u00e7mak, hareketleri tan\u0131mak veya sevilen bokeh<\/em> efektini (foto\u011fraflarda odak d\u0131\u015f\u0131 bir arka plan) olu\u015fturmak i\u00e7in bu teknoloji kullan\u0131l\u0131yor.<\/p>\n

Bu g\u00f6revleri yerine getirebilmek i\u00e7in ak\u0131ll\u0131 telefonun kameraya neyin yak\u0131n, neyin daha uzakta oldu\u011funu bilmesi, bunun i\u00e7in de \u00fc\u00e7 boyutlu bir resim g\u00f6rmesi gerekiyor. \u0130\u015fte bu i\u015f, ToF taraf\u0131ndan ger\u00e7ekle\u015ftiriliyor (bu arada, k\u0131saltma U\u00e7u\u015f S\u00fcresi anlam\u0131na geliyor): Sens\u00f6r bir k\u0131z\u0131l\u00f6tesi \u0131\u015f\u0131n yay\u0131yor ve \u0131\u015f\u0131nlar\u0131n geri yans\u0131mas\u0131 i\u00e7in ge\u00e7en s\u00fcreyi \u00f6l\u00e7\u00fcyor. Bu s\u00fcre ne kadar uzunsa nesne sens\u00f6rden o kadar uzak oluyor.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, ToF mod\u00fcllerinin temel g\u00f6revlerine ek olarak casus kamera bulma konusunda da iyi bir i\u015f \u00e7\u0131kard\u0131\u011f\u0131n\u0131 ke\u015ffetti. Bunun nedeni, sens\u00f6r taraf\u0131ndan yay\u0131lan \u0131\u015f\u0131\u011f\u0131n, lens \u00fczerinde casus cihaz\u0131n tan\u0131nabilece\u011fi karakteristik bir parlama olu\u015fturmas\u0131.<\/p>\n

Sens\u00f6re seviye atlatmak<\/h2>\n

ToF \u00f6zellikli ak\u0131ll\u0131 telefon kamera uygulamalar\u0131 \u00e7ok farkl\u0131 ama\u00e7lar i\u00e7in olu\u015fturuldu\u011fundan, ara\u015ft\u0131rmac\u0131lar\u0131n ayr\u0131 bir uygulama geli\u015ftirmesi ve sens\u00f6r\u00fcn becerilerini gizli kameralardan gelen parlamay\u0131 daha iyi ay\u0131rt edecek \u015fekilde desteklemesi gerekiyordu.<\/p>\n

\u0130lk olarak, kullan\u0131c\u0131ya nesneleri taramak i\u00e7in en uygun aral\u0131\u011f\u0131 bildiren ak\u0131ll\u0131 bir sistem eklediler. Ak\u0131ll\u0131 telefon \u015f\u00fcpheli bir nesneye \u00e7ok yak\u0131nsa gelen parlama \u00e7ok parlak olacak ve sens\u00f6r\u00fc \u201ca\u015f\u0131r\u0131 doygun\u201d hale getirecekti. Ayn\u0131 \u015fekilde, cihaz \u00e7ok uzaktaysa parlama \u00e7ok zay\u0131f olacak ve detekt\u00f6r onu tespit edemeyecekti.<\/p>\n

Ekip, ikinci olarak, yabanc\u0131 sinyalleri elemek i\u00e7in bir filtre uygulad\u0131. Bunun nedeni, detekt\u00f6r\u00fcn gizli bir merce\u011fi yaln\u0131zca s\u0131n\u0131rl\u0131 bir g\u00f6r\u00fc\u015f alan\u0131nda, yani ak\u0131ll\u0131 telefonun kameras\u0131ndan \u00e7\u0131kan yakla\u015f\u0131k 20\u00b0\u2019lik bir koni i\u00e7erisinde az \u00e7ok do\u011fru tan\u0131mlayabilmesiydi. Bu koninin d\u0131\u015f\u0131ndaki herhangi bir \u015fey detekt\u00f6r\u00fcn kafas\u0131n\u0131 kar\u0131\u015ft\u0131r\u0131p yanl\u0131\u015f pozitiflere yol a\u00e7\u0131yordu.<\/p>\n

Son olarak, uzmanlar yanl\u0131\u015f pozitif oran\u0131n\u0131 daha da azaltmak i\u00e7in kendi kendine \u00f6\u011frenen programlanabilir filtreler uygulad\u0131. ToF sens\u00f6rlerinin \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011f\u00fc \u00e7ok d\u00fc\u015f\u00fckt\u00fc (yaln\u0131zca 320\u00d7240 piksel). Bu nedenle, detekt\u00f6r\u00fcn parlaman\u0131n tam boyutunu, \u015feklini ve yo\u011funlu\u011funu (yani tam olarak bir gizli kameray\u0131 di\u011fer zarars\u0131z nesnelerden ay\u0131ran parametreleri) belirlemesi kolay de\u011fildi.<\/p>\n

Test sonu\u00e7lar\u0131<\/h2>\n

Ara\u015ft\u0131rmac\u0131lar, y\u00f6ntemin pratikte ne kadar etkili oldu\u011funu belirlemek i\u00e7in bir deney yapt\u0131lar. \u00c7al\u0131\u015fmaya kat\u0131lan 379 g\u00f6n\u00fcll\u00fcden casus kameralar\u0131 \u00fc\u00e7 farkl\u0131 y\u00f6ntem kullanarak bulmalar\u0131 istendi: \u00c7\u0131plak g\u00f6zle, \u015fu anda piyasada bulunan \u00f6zel bir detekt\u00f6rle ve LAPD ile. Arama yapmalar\u0131 i\u00e7in 30-60 saniye verildi; ortalama bir gezginin bu aktivite i\u00e7in harcamaya haz\u0131r oldu\u011fu s\u00fcre buydu.<\/p>\n

\u0130lk y\u00f6ntem pek etkileyici olmayan sonu\u00e7lar verdi. Kat\u0131l\u0131mc\u0131lar\u0131n sadece %46\u2019s\u0131 gizli kameralar\u0131 yaln\u0131zca \u00e7\u0131plak g\u00f6zle tespit edebildi. Dahas\u0131, \u00e7ok say\u0131da yanl\u0131\u015f pozitif vard\u0131: Vakalar\u0131n %54,9\u2019unda g\u00f6n\u00fcll\u00fcler yanl\u0131\u015f nesnelere veya yerlere i\u015faret etti.<\/p>\n

\u00d6zel detekt\u00f6r de iyi sonu\u00e7 vermedi: \u0130ki farkl\u0131 tarama modunda casus kameralar\u0131 bulan kat\u0131l\u0131mc\u0131lar\u0131n oran\u0131 yaln\u0131zca %62,3 ve %57,7 oldu. Yanl\u0131\u015f pozitiflerin say\u0131s\u0131 yine y\u00fcksekti: \u0130ki modda s\u0131ras\u0131yla %26.9 ve %35.2.<\/p>\n

En etkili y\u00f6ntemin LAPD oldu\u011fu kan\u0131tlad\u0131. Casus kameralar, vakalar\u0131n %88,9\u2019unda bulundu. Ara\u015ft\u0131rmac\u0131lar aramay\u0131 daha zor hale getirmek i\u00e7in ayd\u0131nlatmay\u0131 de\u011fi\u015ftirdi\u011finde bile tespit oran\u0131 %77,8\u2019in alt\u0131na d\u00fc\u015fmedi. Yanl\u0131\u015f pozitiflerin pay\u0131 da %16,67 ile d\u00fc\u015f\u00fckt\u00fc.<\/p>\n

\u00c7al\u0131\u015fma s\u00fcr\u00fcyor<\/h2>\n

Etkileyici test sonu\u00e7lar\u0131na ra\u011fmen, yak\u0131n zamanda App Store veya Google Play\u2019de bir LAPD uygulamas\u0131 g\u00f6rmeyece\u011fiz. Ara\u015ft\u0131rmac\u0131lar\u0131n dedi\u011fine g\u00f6re modern ToF sens\u00f6rleri, saha i\u00e7i \u00e7al\u0131\u015fma i\u00e7in hala yeterli \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011fe ve hatas\u0131zl\u0131\u011fa sahip de\u011fil; ayr\u0131ca, t\u00fcm ak\u0131ll\u0131 telefonlarda b\u00f6yle bir mod\u00fcl yok. Bu nedenle, tasar\u0131m iyile\u015ftirilene ve \u00fcreticiler yeni kameralar piyasaya \u00e7\u0131kana kadar kullan\u0131c\u0131lar\u0131n sab\u0131rl\u0131 olmas\u0131 ve gizli kameralar\u0131 bulmak i\u00e7in di\u011fer y\u00f6ntemlere<\/a> ba\u015fvurmas\u0131 gerekecek.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
