Abstract
U teorijskom dijelu ovog diplomskog rada opisuju se moderne metode raspoznavanja i autentifikacije korisnika u računalnim sustavima. Objašnjena je važnost i načini raspoznavanja korisnika. Obrađena je biometrijska identifikacija, neki njeni tipovi i njihove specifičnosti. Naglasak je stavljen na metode zasnovane na postupcima strojnog učenja i raspoznavanja uzoraka. Posebno je obrađena metoda raspoznavanja korisnika na temelju potpisa. Opisani su neki postupci strojnog učenja, algoritmi za klasifikaciju, dubinsko učenje i istražena su postojeća rješenja autentifikacije korisnika na Android platformi. U praktičnom dijelu rada ostvareno je programsko rješenje za raspoznavanje korisnika na mobilnoj platformi na temelju potpisa. Programsko rješenje izrađeno je za Android platformu i koristi fotoaparat za slikanje potpisa. Fotografija se prosljeđuje istreniranom modelu koji određuje je li potpis originalan. Ukoliko je uspješno autentificiran, korisnik je u mogućnosti pristupiti sadržaju aplikacije. U protivnom mu se pristup zabranjuje.
Abstract (english)
In the first part of this thesis, modern user authentication and recognition methods in computer systems are described. It is described how important user recognition can be and which ways of recognizing users exist. Biometric identification and its types are explained. Methods based on machine learning and classification methods are given emphasis in this paper, especially signature recognition methods. Furthermore, some important classification algorithms and machine learning techniques are explained and existing solutions to these topics are explored for Android platform. An Android application has been developed as a practical part of this thesis. Application is using phone’s camera for capturing photos of user’s signature and then forwards taken photo to machine learning model which determines whether the signature is original or fake. If successfully authenticated, user is able to access application’s content.
