Abstract

Perkembangan IPTEK yang cepat dan0semakin canggih0terutama dalam0teknologi internet dan multimedia memungkinkan0terjadinya penyimpanan dan penyebaran data baik berupa citra, video0maupun audio dengan mudah, sehingga untuk melindungi0citra digital diperlukan suatu teknik yang dapat meminimalisir0terjadinya pelanggaran0hak cipta teknik tersebut disebut dengan0penyisipan tanda air (watermarking) pada citra digital. Salah satu metode penyisipan tanda air pada citra digital yang cukup sering digunakan adalah Singular Value Decomposition (SVD). Objek yang digunakan untuk sistem simulasi adalah citra asli RGB berukuran 400%2 400 piksel dan 425%2 425 piksel sebagai citra penampung serta sebuah citra RGB berukuran 64%2 64 piksel sebagai citra tanda air. Pengujian*ketahanan*citra*yang memuat*tanda*air dilakukan*dengan*menambahkan*manipulasi*berupa noise*gaussian, speckle, salt & pepper serta*blurring.

Abstract

Stegangraphy is a technique for embed secret message in original image. It has an important role in the field of information hiding for secret communication. Many research about steganograph y tecniques have been developed, one of them is singular value decomposition (SVD). SVD method is popular discused in many tecnique such us steganography and watermarking. In addition to SVD there is a method which can give better result than SVD on watermaring technique that is Shuffled SVD. The differences between SSVD and SVD is in shuffle process which applied before applying SVD. The popularity of SSVD in the watermarking technique made the writer intererest to propose an image steganography tecnique using shuffled singular value decomposition (SSVD). The data used are two original RGB imaage and a message RGB image. Quality measured by PSNR and Correlation Coefficient. The experimental result show that the shuffling process on the secret message caused embedded message can’t read easyly so the secret message is more secure.
