[Primena Voronoi-Delone triangulacija i Katalanovih objekata u zaštiti podataka]: doktorske disertacije

Abstract

This doctoral dissertation is in the field of computer geometry in combination with data protection methods, with an emphasis on the implementation of applications using object-oriented programming techniques. New methods for data protection using Voronoi - Delaunay triangulation were presented. The first method is based on 3D plane encryption in GIS. The second method is based on the authentication of users (clients) of banks, by encrypting the image using the incremental algorithm Voronoi - Delone triangulation and Catalan objects. The third method is the method of steganography, which is based on a combination of Catalan objects and Voronoi - Delone triangulation. The fourth method refers to the proposal of application of one algorithm of computer geometry in the procedure of generating Cryptographic keys from one segment of 3D image.
