\nC\u00e2nd a\u0163i analizat ultima oar\u0103 o bancnot\u0103? Dac\u0103 o ve\u0163i privi cu aten\u0163ie ve\u0163i observa anumite semne particulare menite s\u0103 detecteze falsurile.<\/p>\n
\n\u00cen cadrul unui experiment, specialistul \u00een IT Markus Kuhn a \u00eencercat s\u0103 copieze color o bancnot\u0103 de 20 de euro. \u00cen momentul \u00een care a ap\u0103sat butonul, aparatul a scos un \u0163iuit \u015fi nu a ap\u0103rut nicio copie a bancnotei respective, ci un mesaj printat \u00een diferite limbi, unde se explica faptul c\u0103 este ilegal\u0103 xeroxarea sa.<\/p>\n
\nDup\u0103 o analiz\u0103 mai atent\u0103 a bancnotei, Kuhn a observat mai multe cercuri foarte mici, dispuse sub forma unei \u201econstela\u0163ii\u201d \u015fi \u201ecamuflate\u201d sub diverse semne. De exemplu, pe bancnota de 20 de euro cercule\u0163ele sunt parte a notelor muzicale aflate \u00een design-ul h\u00e2rtiei. <\/p>\n
\nTotu\u015fi, xeroxarea alb-negru a bancnotei nu este detectat\u0103, fapt ce demonstreaz\u0103 c\u0103 aparatul \u201e\u015ftie\u201d c\u00e2nd cineva vrea s\u0103 falsifice bani, culoarea cercule\u0163elor f\u0103c\u00e2nd parte din acel cod. Unii consider\u0103 nu doar culoarea ca fiind o parte important\u0103 a codului, ci \u015fi distan\u0163a dintre cele cinci cercuri.<\/p>\n
\nEste cunoscut faptul c\u0103 \u00een procesul de printare a h\u00e2rtiei banilor se folose\u015fte un model standard de recunoa\u015ftere a bancnotelor valide, dar acesta nu poate fi dezv\u0103luit.<\/p>\n
\nCum detecteaz\u0103 xeroxul particularit\u0103\u0163ile bancnotelor reprezint\u0103, totu\u015fi, un mister pe care reprezentan\u0163ii institu\u0163iilor specifice nu vor s\u0103 \u00eel dezv\u0103luie. Ace\u015ftia afirm\u0103 c\u0103 se iau toate m\u0103surile de precau\u0163ie pentru reducerea \u015fi stoparea falsific\u0103rii de bani. \u00centrebat dac\u0103 aparatele de copiere sunt special programate s\u0103 recunoasc\u0103 acele semne specifice ale bancnotelor, un reprezentat al companiei a afirmat: \u201eXerox, \u00eempreun\u0103 cu alte companii din domeniu, consult\u0103 legisla\u0163ia \u015fi face tot posibilul pentru a stopa amenin\u0163\u0103rile de falsificare a banilor prin intermediul tehnologiei.\u201d<\/p>\n
\nMai exist\u0103, de asemenea, un nivel de codare a bancnotelor mult mai avansat dec\u00e2t \u201econstela\u0163ia\u201d respectiv\u0103, numit Nivelul 3. Despre acesta, \u00eens\u0103, nu discut\u0103 nimeni, Banca Central\u0103 fiind singura cunosc\u0103toare a acestui \u201esecret\u201d.<\/p>\n
\nDe\u015fi a pornit o mic\u0103 investiga\u0163ie pentru a-\u015fi satisface aceast\u0103 curiozitate, retincen\u0163a \u00een r\u0103spunsuri a celor \u00eentreba\u0163i l-a determinat pe Markus Kuhn s\u0103 afirme, \u00een cele din urm\u0103: \u201ePoate nu vom avea niciodat\u0103 suficiente informa\u0163ii despre tehnologiile care combat falsificarea de bani, dar cred c\u0103 a\u015fa este mai bine.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
