Perbandingan Algoritma Discrete Cosine Transform (DCT-2D), Algoritma Discrete Wavelet Transform (DWT) dan Algoritma Least Significant Bit Insertion (LSB) pada Steganografi Video

Abstract

In the era of Industry 4.0, the development of multimedia and the internet has facilitated the distribution and transmission of information. However, security and confidentiality of information often pose significant challenges. One way to address this is through steganography techniques, which allow the hiding of secret information within digital media without attracting the attention of third parties. The Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) algorithms are two commonly used techniques in steganography for embedding data into digital media such as images and videos. In this study, we propose a comparison between the DCT-2D algorithm, DWT, and the Least Significant Bit (LSB) insertion method in video steganography. Through the performance analysis of these three algorithms, this research aims to provide a better understanding of the effectiveness and relative advantages of each approach in concealing secret information within videos.
