We avoid the data to be modified by attacker and broadcast the wrong message. We propose the method to collect the news and store them in computer system in security. We encrypt the news and store the encrypted news in the encrypted news database. We set encryption data table and use it to encrypt the news file to encrypted news data. The news has different location code in the news information database. We use location code to insert encryption data table to encrypted news and store the encrypted news to encrypted news database. We create the broadcast list table to broad the order of news. When we want to broadcast, we decrypt the encrypted news first and then show out. We use this location code of news in the news information database to get encryption data table in the encrypted news. We use encryption data table to do decryption. When we install these algorithms in the computer system to process, it is securer.
