New application for multi-factor user authentication in two spectral areas is created. Application use a method of separating information using INFRAREDESIGN® technology. The application employs two cameras in two spectral areas: VIS (visible) 400-750 nm and NIR (near-infrared) at 1000 nm, and is capable of detecting human faces and QR codes. One of the key features of the application is the verification of user authenticity through multiple factors simultaneously. Detection of faces, QR codes, and other markers provides an additional level of security, while simultaneous authenticity checks in both spectral areas ensure that information separation is correctly performed for the same individual, object, or marker. Separation is accomplished using INFRAREDESIGN® technology, and this approach enhances the security of the authentication system as users must go through multiple verification steps to gain access. The application also allows for capturing images of "regions of interest" in both spectral areas for further deep learning or analysis. Multi-factor authentication takes place simultaneously in real-time in both spectral areas using multiple detection algorithms. During this presentation the spotlight is on multiple examples INFRAREDESIGN® secured items for dual-spectrum authentication using two cameras. This will encompass not only the detection process but also the real-time visual representation of authentication, leading to access approval.

Prof. dr. sc. Jana Žiljak Gršić, scientific adviser:

In 1996, she graduated from the Design Study at the Faculty of Architecture, University of Zagreb, and in 2007, she received her doctorate from the Faculty of Graphic Arts, University of Zagreb. For the innovation Infraredizajn, she received the national science award in 2010 for scientific discovery and the Nikola Tesla Award for the best Croatian innovation in 2012, as well as more than 100 prestigious world awards, which she shares equally with her colleagues.

She has been the dean of the Zagreb University of Applied Sciences since 2021, where she has been employed since 2002. She teaches at the North University on graduate and doctoral studies as her secondary employment. As an external associate, she teaches at the doctoral studies of the Faculty of Graphic Arts, University of Zagreb, and at the doctoral studies of Alma Mater Europaea in Maribor.

She is the secretary of the graphic engineering department of the Croatian Academy of Engineering for the term 2022 - 2026. She is the founder and member of the editorial board of the Polytechnic & Design journal published by the Zagreb University of Applied Sciences. She is the head and editor of the collection of the professional-scientific conference Printing and Design, which is held under the sponsorship of the Croatian Academy of Engineering. She is a member of several expert councils and expert commissions and a regular member of the Croatian Designers Association.

She is a permanent court expert witness for graphic technology, design, manuscripts, documents, securities, money, pictures, credit cards, and other cards.

She participated in ten scientific, professional and technological projects approved by the Ministry of Science and Education and the Croatian Science Foundation. Together with her collaborators, she has registered four patents at the State Intellectual Property Office. She actively participated in the development of the curriculum of the Informatics and Computing Department of the Zagreb University of Applied Sciences, and she designed the program of the Informatics Design major at the professional and graduate studies in Informatics. She introduced numerous courses in the fields of design, web design, 3D modeling, visual communication, security graphics and innovation, which she teaches. She participated in the launch of the new study program Information Security and Digital Forensics at Zagreb University of Applied Sciences and in the internationalization of the said study program. In two terms, she was the head of the professional study of informatics and in two terms the head of the Informatics and Computing Department of Zagreb University of Applied Sciences.

She is the author of the textbook Safety graphics published by the Zagreb University of Applied Sciences and published numerous professional works, including those in collaboration with students of the Zagreb University of Applied Sciences (CROSBI Profile: 34737, MBZ: 264064). She is the author of many visual identities, posters and packaging for a wide range of customers. She has participated in solo exhibitions and group international and domestic juried exhibitions in the field of design and innovation. She organized exhibitions of student works in recognized galleries of the City of Zagreb and encouraged the application of students and teachers to innovation exhibitions in the country and around the world. She led the project in which IT design students participated named Techno Past Techno Future: European Researchers' Night (TPTF_ERN) Marie S. Curie European Research Night, EU Framework Program for Research and Innovation in 2018 and 2019.

Silvio Plehati, MEng(IT), MSc(Graph.Techn.), Lecturer at Zagreb University of Applied Sciences:

In 2003, Silvio Plehati completed his undergraduate studies in Information Technology at the Zagreb University of Applied Sciences. In 2010, he completed his graduate studies in Information Technology at the same faculty. In 2023, he completed the study of Graphic Technology at the Faculty of Graphic Arts, University of Zagreb. That same year, at the Faculty of Graphic Arts, he was awarded the Dean's Award  for publishing two scientific papers of category A (Q1/Q2) in 2022/2023. In 2023, he enrolled in a doctoral program at the same faculty. Since 2003, he has been continuously working in the field, establishing a bridge between computer science and graphic technology. He has co-authored professional and scientific papers in the fields of graphic engineering and graphic programming, focusing on the design of graphic protections through programming. Since 2021, he has been employed at the Zagreb University of Applied Sciences. He was appointed as an assistant in 2021 and promoted to lecturer in 2023. He teaches courses in software engineering in open systems, object-oriented programming, and advanced programming techniques. His areas of interest include C languages, graphic programming languages, 2D and 3D graphics, 3D printing, micro (embedded) electronics, and sensors. He actively participates in conferences related to graphic engineering, graphic programming, and computer science.
