Perancangan Aplikasi Steganografi Pada Citra Digital Menggunakan Algoritma Diversity Untuk Keamanan Pesan

Abstract

The rapid advancement of digital technology and internet communication necessitates robust information security mechanisms that not only protect message content but also conceal the existence of the communication itself. Steganography provides an effective approach by embedding secret messages within digital media, particularly digital images. This study aims to design of Steganography Application in Digital Images Using the Diversity Algorithm for Message Security. The research adopts an applied research methodology with a system design and implementation approach. The Diversity algorithm is employed to exploit variations in pixel color values for embedding message bits, resulting in a more randomized embedding pattern that is resistant to detection and analysis. The experimental results demonstrate that the proposed system is capable of embedding and extracting text messages accurately without degrading the original image information. Furthermore, the steno-image maintains high visual quality, indicating good imperceptibility of the embedded data. In conclusion, the developed application proves to be an effective and reliable solution for secure message transmission using digital image-based steganography.
