\n\t\t\t\t\t\t\t\t\tFinansiel svindel bliver stadig mere organiseret, automatiseret og vanskelig at opdage med traditionelle v\u00e6rkt\u00f8jer. De fleste systemer til svindeldetektion analyserer transaktioner enkeltvis \u2014 \u00e9t login, \u00e9n betaling eller \u00e9n enhed ad gangen \u2014 hvilket skaber blinde vinkler, som professionelle svindelnetv\u00e6rk kan udnytte. Ved at koordinere tusindvis af sm\u00e5 og tilsyneladende uafh\u00e6ngige handlinger p\u00e5 tv\u00e6rs af mange konti skjuler angribere deres aktivitet i relationerne mellem brugerne frem for i de enkelte h\u00e6ndelser.

Projektet Fraud Detection in Payments adresserer denne udfordring ved at betragte digital finansiel aktivitet som et netv\u00e6rk af forbundne relationer. Denne grafbaserede tilgang g\u00f8r det muligt at g\u00e5 fra reaktiv overv\u00e5gning til proaktivt cyberforsvar. L\u00f8sningen bidrager til at beskytte nordisk betalingsinfrastruktur, styrke borgernes \u00f8konomiske sikkerhed og underst\u00f8tte teknologisk uafh\u00e6ngighed gennem en dansk ejet l\u00f8sning, der er i tr\u00e5d med europ\u00e6iske standarder for transparens, AI-etik og databeskyttelse.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\tProjektet forbedrer svindeldetektion ved at kombinere avanceret grafanalyse med kravene fra virkelige driftssystemer. Forskerne udvikler sammen med Vipps MobilePay og Retix et softwarebaseret forsvarslag, som kan opdage organiseret svindel i realtid og i stor skala. Forskningen fokuserer p\u00e5 to komplement\u00e6re metoder: hurtige grafalgoritmer i hukommelsen, der kan stoppe koordinerede botangreb inden for millisekunder, samt dybere batchanalyse af historiske data for at afd\u00e6kke skjulte svindelnetv\u00e6rk og komplekse m\u00f8nstre for hvidvaskning af penge.

De centrale videnskabelige udfordringer omfatter inkrementel klyngedannelse i meget store grafer, densitetsbaseret klyngedannelse i ikke-euklidiske rum samt p\u00e5lidelige og transparente grafneurale netv\u00e6rk, der er modstandsdygtige over for manipulation. Ved at integrere forskningen i en industriel platform forbinder projektet teori og praksis og oms\u00e6tter avanceret grafvidenskab til et praktisk forsvarssystem med lav latenstid til moderne betalingsplatforme.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Forskningen fokuserer p\u00e5 to komplement\u00e6re metoder: hurtige grafalgoritmer i hukommelsen, der kan stoppe koordinerede botangreb inden for millisekunder, samt dybere batchanalyse af historiske data for at afd\u00e6kke skjulte svindelnetv\u00e6rk og komplekse m\u00f8nstre for hvidvaskning af penge.<br><br>De centrale videnskabelige udfordringer omfatter inkrementel klyngedannelse i meget store grafer, densitetsbaseret klyngedannelse i ikke-euklidiske rum samt p\u00e5lidelige og transparente grafneurale netv\u00e6rk, der er modstandsdygtige over for manipulation.
