Pengembangan Metode Quad Smoothness Reduced Difference Expansion Untuk Steganography Pada Audio

Jurnal Teknik ITS, 2018
Steganography adalah salah satu bagian dari teknik penyembunyian data. Tujuan utama dari steganography adalah untuk menjaga orang lain agar tidak mengetahui informasi rahasia yang disembunyikan. Banyak penelitian yang telah dilakukan dalam bidang ini, khususnya steganography dengan media citra digital. Pada penelitian ini akan dilakukan penyembunyian

A hybrid steganography scheme with reduced difference expansion and pixel-value ordering

IAES International Journal of Artificial Intelligence (IJ-AI)
<p><span lang="EN-US">Steganography embeds secret messages into public media while ensuring the stego content remains visually indistinguishable from the original. The primary challenge lies in maximizing embedding capacity and image quality without introducing noticeable distortions.

Reversible Video Steganografi Menggunakan Metode Improved Reduced Difference Expansion dan Analisis Gray Level Co-occurrence Matrix [PDF]

Jurnal Teknik ITS, 2016
Saat ini penelitian mengenai steganografi telah banyak dilakukan, namun metode yang digunakan hanya berfokus pada media citra. Dimana metode ini memiliki kelemahan yaitu media yang digunakan media penyisipan tidak dapat dikembalikan. Tidak hanya itu berkas gambar juga memiliki kelemahan terbatasnya jumlah pixel yang tersedia pada suatu citra.
