PENYISIPAN PESAN KE DALAM FILE VIDEO MENERAPKAN METODE CHINESE REMAINDER THEOREM

Abstract

Nowadays the use of information technology as a medium of information exchange is developing very widely. Various types of information such as text, images, sound and video can be converted into digital media that allows it to be reproduced or transmitted through various media. One of them is the internet, through the internet we can easily exchange information with other people in various places. However, there are times when information / messages are confidential, where no other party may know the contents of this information other than the sender and recipient. Then we need a security for the message. Steganography is a technique and art for inserting messages or information in a media, such as text, images, audio or video that aims to avoid suspicion from people who are not entitled. Therefore required a software that can insert or hide confidential information on a media that is video. But in doing the insertion of messages on the video using steganography alone is not necessarily safe, so we need a useful method to improve security because it requires the Chinese Remainder Theorem method. The research objective is to apply the Chinese Remainder Theorem method to insert text messages into video files. This is necessary because it often happens that the text message sent is a secret message that should not be known to just anyone. Chinese Remainder Theorem is a useful method for providing benefits in terms of increased security and low computational complexity.
