Analisis Rainbow Antimagic Coloring dan Aplikasinya pada Biometric Image Encryption Menggunakan Teknik Caesar Cipher

Abstract

This research focuses on the analysis of rainbow antimagic coloring and its application to biomertic image encryption using the Caesar cipher technique. Rainbow antimagic coloring is a concept that combines labeling and graph coloring. Where every two points in the graph have at least one rainbow path. From the results of rainbow antimagic labeling on the graph, an adjacency matrix of its side weight values is created. The adjacency matrix is used as the ”key” in encrypting the image. Then the ”key” is operated with the plain image using the caesar cipher technique to obtain the cipher image. This method proves to be effective in encrypting images, because it is proven that the encryption results meet the standards of a good cipher image. The biometric used in this research is palmprints, palmprints were chosen because they are considered more complex than fingerprints or faces that are easier to detect. For someone who has a position or a lot of assets, personal data is very important and is a privacy that needs to be maintained.
