C\u00e2t de sigur este smartphone-ul t\u0103u \u00eempotriva poten\u021bialilor hackeri? Sper c\u0103 utiliza\u021bi un fel de sistem de securitate pe gadgetul dvs. pentru a v\u0103 proteja confiden\u021bialitatea.<\/p>\n

\u00cen prezent, exist\u0103 mai multe moduri de a bloca \u0219i debloca telefoanele noastre \u2013 amprente digitale, irisi, parole, modele, recunoa\u0219tere facial\u0103 \u0219i multe altele.<\/p>\n

Cu toate acestea, de c\u00e2nd Apple a adoptat tehnologia Face ID cu iPhone X, XS, XS Max \u0219i XR, recunoa\u0219terea facial\u0103 este acum o caracteristic\u0103 biometric\u0103 comun\u0103 \u00een majoritatea smartphone-urilor. Acest lucru, desigur, permite utilizatorului s\u0103 deblocheze telefonul prin simpla privire la el.<\/p>\n

Din p\u0103cate, multe smartphone-uri care implementeaz\u0103 \u00een prezent sistemul de recunoa\u0219tere facial\u0103 sunt \u00eenc\u0103 vulnerabile la cel mai simplu hack dintre toate - o fotografie a proprietarului.<\/p>\n

Citi\u021bi mai departe \u0219i vede\u021bi de ce nu ar trebui s\u0103 utiliza\u021bi recunoa\u0219terea fe\u021bei pe unele telefoane.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

Recunoa\u0219terea fe\u021bei nu este sigur\u0103<\/h4>\n

Un studiu al grupului olandez de protec\u021bie a consumatorilor Consumentenbond a dezv\u0103luit c\u0103 multe smartphone-uri care folosesc recunoa\u0219terea facial\u0103 pentru securitatea biometric\u0103 pot fi p\u0103c\u0103lite cu u\u0219urin\u021b\u0103 doar cu o singur\u0103 fotografie.<\/p>\n

Cercet\u0103torii au testat un total de 110 de telefoane, iar rezultatele au ar\u0103tat c\u0103 42 dintre ele ar putea fi p\u0103c\u0103li\u021bi cu u\u0219urin\u021b\u0103 de o imagine a proprietarilor lor. Raportul nu dezv\u0103luie calitatea fotografiilor folosite, dar men\u021bioneaz\u0103 c\u0103 folosesc fotografii portret bune pentru testele lor.<\/p>\n

Prin urmare, putem presupune cu siguran\u021b\u0103 c\u0103 fotografiile care sunt \u00eenc\u0103rcate pe re\u021belele sociale, cum ar fi Facebook \u0219i Instagram, vor putea p\u0103c\u0103li cu u\u0219urin\u021b\u0103 sistemul de recunoa\u0219tere facial\u0103.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

Recunoa\u0219terea facial\u0103 este de neegalat<\/h4>\n

De\u0219i 42 dintre telefoane sunt vulnerabile la deblocarea fotografiilor, 68 de dispozitive, inclusiv telefoane echipate cu Face ID \u0219i modele mai noi de la Samsung, Lenovo, Motorola \u0219i HTC, nu sunt expuse riscului din aceast\u0103 metod\u0103.<\/p>\n

\u00cen plus, mai multe modele pot fi deblocate cu o fotografie, dar utilizatorii \u00ee\u0219i pot \u00eembun\u0103t\u0103\u021bi set\u0103rile de recunoa\u0219tere facial\u0103 pentru a face recunoa\u0219terea \u00een sine mai dificil\u0103.<\/p>\n

De asemenea, am observat c\u0103 majoritatea telefoanelor mai sigure sunt modele mai noi (cel mai evident cu telefoanele Samsung Galaxy). Acest lucru sugereaz\u0103 c\u0103 produc\u0103torii de telefoane au schimbat sistemele de recunoa\u0219tere facial\u0103 \u0219i \u00ee\u0219i \u00eembun\u0103t\u0103\u021besc \u00een mod constant datele biometrice.<\/p>\n

De ce sunt aceste telefoane mai noi rezistente la deblocarea fotografiilor? Ei bine, au un hardware mai sofisticat de recunoa\u0219tere facial\u0103 care urm\u0103re\u0219te fe\u021bele \u00een 3D.<\/p>\n

Apple, \u00een special, folose\u0219te o camer\u0103 cu infraro\u0219u frontal\u0103, un reflector \u0219i un proiector \u00een sistemul s\u0103u de recunoa\u0219tere facial\u0103.<\/p>\n

Ace\u0219ti senzori lucreaz\u0103 \u00eempreun\u0103 pentru a v\u0103 popula fa\u021ba cu 30.000 de puncte invizibile care v\u0103 urm\u0103resc fa\u021ba \u00een 3D, apoi creeaz\u0103 un model care este stocat \u00een siguran\u021b\u0103 pe telefon. De fiecare dat\u0103 c\u00e2nd te ui\u021bi la el, sistemul compar\u0103 modelul fe\u021bei pentru a se potrivi cu ceea ce vede.<\/p>\n

Alte telefoane folosesc metode similare, dar Face ID de la Apple este \u00een continuare lider.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

Func\u021bia de recunoa\u0219tere facial\u0103 a Huawei este suficient de sigur\u0103?<\/h4>\n

Huawei Mate 20 Pro este prima \u00eencercare a Huawei de a include o metod\u0103 de scanare facial\u0103 3D care, teoretic, func\u021bioneaz\u0103 identic cu Face ID de la Apple. Dar o descoperire recent\u0103 a Android Pit arat\u0103 c\u0103 recunoa\u0219terea facial\u0103 3D a lui Huawei Mate 20 Pro poate fi deblocat\u0103 de cineva cu o oarecare asem\u0103nare cu proprietarul ini\u021bial al telefonului.<\/p>\n

 <\/p>\n

Potrivit raportului, Mate 20 Pro a fost transmis prin birou pentru ca toat\u0103 lumea s\u0103 vad\u0103 \u0219i s\u0103 testeze telefonul. \u00cen timpul acestei demonstra\u021bii, o persoan\u0103 cu o u\u0219oar\u0103 asem\u0103nare cu proprietarul telefonului a putut s\u0103 deblocheze telefonul folosind func\u021bia de deblocare facial\u0103.<\/p>\n

Au fost efectuate retest\u0103ri doar pentru ca acela\u0219i lucru s\u0103 se \u00eent\u00e2mple din nou..<\/p>\n

Scuza Huawei este c\u0103 ei lanseaz\u0103 o declara\u021bie de declinare a r\u0103spunderii care spune c\u0103 func\u021bia lor de deblocare facial\u0103 3D este \u00een prezent nesigur\u0103. Cu toate acestea, acest lucru nu r\u0103spunde la \u00eentrebarea cum au putut dou\u0103 persoane cu caracteristici similare (care nu sunt gemeni) s\u0103 deblocheze acela\u0219i telefon. gresie de bucatarie<\/span><\/a><\/p>\n

Raportul mai spune c\u0103 exist\u0103 c\u00e2teva tr\u0103s\u0103turi cheie care disting cele dou\u0103 fe\u021be, chiar dac\u0103 au b\u0103rbi groase \u0219i p\u0103r scurt. Cei doi b\u0103rba\u021bi au culoarea pielii diferite, contururi \u0219i culoarea ochilor diferite. Asta nu este tot. Unul dintre ei poart\u0103 \u0219i ochelari, iar cel\u0103lalt nu.<\/p>\n

Ambele dispozitive Mate 20 Pro ruleaz\u0103 aceea\u0219i versiune de software, cu num\u0103rul de versiune 9.0.0.113 (C432E10R1P16). Deoarece ambele produse erau variante de pre-produc\u021bie, cea mai u\u0219oar\u0103 explica\u021bie aici ar putea fi aceea c\u0103 ambele modele au software care nu poate fi implementat cu unit\u0103\u021bile v\u00e2ndute.<\/p>\n

\u00cen orice caz, Huawei nu a spus \u00eenc\u0103 nimic oficial \u00een aceast\u0103 privin\u021b\u0103.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div>
