MP4 files are information in the form of video, Information becomes very vulnerable to be known, retrieved or even manipulated and misused by other parties who are not entitled. In this research combines the classic algorithm vigenere cipher with modren algorithm that is Railfance algorithm in securing MP4 files, with the system built then every MP4 file uploaded into the system will be translated into binary code with base64 technique which is plaintext and then will be encrypted with vigenere cipher algorithm and continued encryption using railfance algorithm and produce MP4 file that can not be played , so mp4 files are considered damaged, when not. For decryption and vice versa MP4 files that can not be played dupload into the system will be translated into binary code with base64 technique which is plaintext and then decrypted with railfance algorithm and continued decryption using vigenere cipher algorithm and produce MP4 files that can be played.
