Speech Title: Digital Passports: Biometric & Vaccine Information

Abstract: In the near future, digital passports may be required to travel between countries. A digital passport contains biometric information to verify the identity of its holder. After Covid-19 outbreak the digital passport will also contain a vaccine document which shows that a passenger has been vaccinated or tested for coronavirus. In this work, a unified frame work which provides higher security level to digital passports and vaccine document is proposed. This framework integrates face, iris, fingerprint images and vaccine document. It involves three layers of security: the first layer maps a biometric image to another biometric image which we called biostego image. Three mapping schemes are proposed: the first scheme maps single biometric image to single biostego image, the second scheme maps dual biometric images to single biostego image, the third scheme divides the biometric image into sections and maps each section to different biostego image. A mapping function maps the intensity value of each pixel in the biometric image to pixels with same intensity in the biostego image. A representative pixel is randomly selected from the set of pixels, its coordinates are recorded in the location map of the biometric image. In the second layer, the location map and vaccine document are both encoded using fingerprint fuzzy vaults. In the third layer, the encoded location map is hidden in the biostego image using steganography technique. Finally, the biostego image which contains the encoded location map and vaccine document are stored in the digital passport’s memory. Keeping the mapping scheme secret and by using the fingerprints fuzzy vault to encrypt location map the proposed approach provides higher level of protection against fraud.

Biography: Dr. Khaled Nagaty is a Professor in Image Processing and the Director of University eLearning at the British University in Egypt based in El Sherouk city. Professor Nagaty has published over 40 papers many of them on Biometrics. His Ph.D. in Biometrics was published in the form of printed book by Lap Lambert in Germany, 2012. He is a recognized expert in Biometrics with specialization in fingerprints classification and identification and face recognition giving many invited papers at international meetings around the world. After obtaining B.Sc. Degree in Statistics from the University of Cairo in 1982, he started work at the Criminal Evidence Department (CFD) in Cairo. During his time at the CFD and later he continued his research in Biometrics and obtaining his Ph.D. in this field in1999. Dr. Nagaty joined Ain Shams University in Egypt in 2000 as a Lecturer in Computer Science and continued his work in the field of Biometrics. In 2007, he promoted to Associate Professor in Computer Science and in 2008 he moved to the British University in Egypt (BUE) at El Sherouk city where he was responsible for teaching Computer Science and its applications in the field of Biometrics and Image Processing. In 2016, he was promoted to Professor in Biometrics and Image Processing and currently he is a permanent Professor at the BUE in Egypt.
