Abstract

Steganography merupakan salah satu metode yang digunakan untuk menyembunyikan informasi. Dengan steganography, informasi akan disembunyikan dengan cara menyisipkan informasi tersebut kedalam data lain. Contoh dari steganography adalah histogram shifting dan neighbouring similarity. Histogram shifting dan neighbouring similarity memiliki sifat reversible, yang berarti video hasil penyisipan dapat dikembalikan lagi seperti semula. Pada Tugas Akhir ini dilakukan pengembangan metode histogram shifting dan neighbouring similarity dengan cara menggabungkan kedua metode tersebut serta melakukan modifikasi pada arah pergeseran bit dan letak penyisipan. Dari data hasil uji coba, jumlah payload yang bisa dimasukkan meningkat sebanyak 88% dari metode neighbouring similarity dan meningkat sebanyak 1658% dari metode histogram shifting. Nilai PSNR juga meningkat sebanyak 2,1% dari metode neighbouring similarity dan meningkat sebanyak 18,01% dari metode histogram shifting. ===========================================================================================Steganography is one of the methods used to hide information. With steganography, the information will be hidden by inserting that information into other data. An example of steganography is a histogram shifting and neighbouring similarity. Histogram shifting and neighbouring similarity have reversible properties, that mean the video result of embedding can be restored as same as before. In this Final Project, histogram shifting and neighbouring similarity is modified by combining both methods and modifying the direction and the location of the shifting. From the data of the test result, the number of payloads that can be entered increases as much as 88% of the neighbouring similarity method and increases as much as 1658% of the histogram shifting method. The PSNR score also increased by 2.1% from the neighbouring similarity method and increased by 18.01% of the histogram shifting method.
