Otu ndị nyocha sitere na Mahadum Padua (Italy) na Mahadum Delft (Netherland) ebipụtala usoro maka iji igwe mmụta iji wughachi koodu PIN abanyela site na ndekọ vidiyo nke mpaghara ntinye aka kpuchiri nke ATM. . Mgbe ị na-abanye koodu PIN ọnụọgụ anọ, enwere ike ibu amụma koodu ziri ezi na 4%, na-eburu n'uche ohere ịme mgbalị atọ tupu igbochi. Maka koodu PIN nke nwere ọnụọgụ 41, puru ibu amụma bụ 5%. Emere nnwale dị iche iche nke ndị ọrụ afọ ofufo 30 nwara ịkọ koodu PIN site na vidiyo ndị e dekọrọ yiri ya. N'okwu a, ohere nke amụma ịga nke ọma bụ 78% mgbe mgbalị atọ gasịrị.
Mgbe ị na-eji nkwụ gị kpuchie panel dijitalụ nke ATM, akụkụ aka nke eji etinye ntinye na-anọgide na-ekpuchi ya, nke zuru ezu iji buru amụma clicks site n'ịgbanwe ọnọdụ aka ma gbanwee mkpịsị aka na-ekpuchighị kpamkpam. Mgbe ị na-enyocha ntinye nke ọnụọgụ ọ bụla, usoro ahụ na-ewepụ igodo ndị a na-apụghị ịpịnye na-eburu n'uche ọnọdụ aka mkpuchi ahụ, ma na-agbakọkwa nhọrọ ndị nwere ike ime maka ịpị dabere na ọnọdụ nke ịpị aka na-adabere na ọnọdụ nke igodo. . Ka iwelie ohere nke nchọpụta ntinye, enwere ike ịdekọ ụda igodo igodo, nke dịtụ iche maka igodo ọ bụla.
Nnwale ahụ jiri usoro mmụta igwe dabere na ojiji nke netwọkụ neural convolutional (CNN) na netwọkụ akwara na-emegharị ugboro ugboro dabere na ụkpụrụ ụlọ LSTM (Long Short Term Memory). Netwọk CNN bụ ọrụ maka iwepụta data gbasara oghere maka etiti ọ bụla, netwọk LSTM jiri data a wepụta usoro na-agbanwe oge. A zụrụ ihe nlereanya a na vidiyo nke ndị mmadụ 58 dị iche iche na-abanye koodu PIN site na iji usoro mkpuchi ntinye ahọpụtara onye so na ya (onye ọ bụla tinyere koodu 100 dị iche iche, ya bụ, ihe atụ ntinye 5800 maka ọzụzụ). N'oge ọzụzụ ahụ, ekpughere na ọtụtụ ndị ọrụ na-eji otu n'ime ụzọ atọ isi kpuchie ntinye.
Iji zụọ ụdị mmụta igwe, a na-eji ihe nkesa dabere na Xeon E5-2670 processor nwere 128 GB nke RAM na kaadị Tesla K20m atọ nwere 5GB nke ebe nchekwa nke ọ bụla. Edere akụkụ ngwanrọ na Python site na iji ọba akwụkwọ Keras na ikpo okwu Tensorflow. Ebe ọ bụ na ntinye ntinye ATM dị iche na nsonaazụ amụma dabere na njirimara dịka nha isi na topology, a chọrọ ọzụzụ dị iche iche maka ụdị panel nke ọ bụla.
Dị ka usoro iji chebe megide usoro mbuso agha a tụrụ aro, a na-atụ aro, ọ bụrụ na ọ ga-ekwe omume, iji koodu PIN nke ọnụọgụ 5 kama 4, ma gbalịakwa iji aka gị kpuchie ohere ntinye dị ka o kwere mee (usoro a na-anọgide na-arụ ọrụ ma ọ bụrụ na ọ dị irè ma ọ bụrụ na ọ dị mkpa. A na-eji aka gị kpuchie ihe dịka 75% nke mpaghara ntinye). A na-atụ aro ndị na-emepụta ATM ka ha jiri enyo nchebe pụrụ iche nke na-ezochi ntinye, yana ọ bụghị n'ibu, kama ntinye ntinye aka, ọnọdụ nke ọnụọgụgụ na-agbanwe na-enweghị usoro.
