Abstract

The rapid development of the internet has increased the ease of sharing information to people around the world. However, this advancement also raises a distress about data manipulation when the data are sent by the sender to the recipient. Therefore, information security is a major problem in data communication. Steganography and cryptography play important roles in the field of information security. Steganography can be applied though various digital media such as video, images, and audio to hide information in such a way that no one else knows that there is a hidden information, except for the relevant parties. Cryptography refers to the art of converting a plaintext (message) into an unreadable format. Both steganography and cryptography techniques are robust. The purpose of this study is to prove that the quality of the results of steganography used to hide secret messages in a video (stego video) using Discrete Wavelet Transform (DWT) and Advanced Encryption Standard (AES) is good. Good quality is measured with Signal to Noise Ratio (PSNR) and Structural Similarity Index (SSIM). The message is encrypted using a cryptography algorithm, AES, to be more secure. The message is then placed into the one frame frequency domain in the video using the DWT method. Video quality before and after the message is inserted is measured based on the PSNR and SSIM values. From the experiments, it is known that the PSNR value ranges between 39 to 40 dB and the SSIM value is close to 1, which means the change of the video frame due to insertion does not cause large noise, thus, the quality of the resulting video stego is satisfactory.
