Today is the age of the digital era which uses ICT around the world in daily life. The confrontation of using ICT is security breach. To protect the daily works and daily messages transferring are more secure as needed, we must take countermeasure to prevent the accidental happening to them. One of those countermeasures is using One Time Pad technique to encrypt and decrypt messages unbreakable. This encryption and decryption will highly secure messages. The amount of data is huge to store and need to be recovered as soon as possible. Most people around the world are using IT system such as banking and Microfinance which its data cost billions dollar. If there is a catastrophe occurring to loss data, their businesses will be bankruptcy. One of the most powerful techniques to recover data effectively is a parity bit. The RAID-5 level has ability to recover data effectively when a hard disk among at least 3 hard disks in array failed during the RAID-5 is working because of its parity bit. This information security method is to ensure the confidential, integrity and availability of data.
