CHAPTER ONE

1.0     Introduction

The ongoing dilemma of digital age is balancing convenience against security. Security is a system safeguards for protecting information technology against disasters, system failure, and an unauthorized access that can result in damage, loss or exposure. There are several reports of spammers, crawlers and hackers who break into people’s privacy to gain illegal access to their data. This has posed greater challenges on people who use database, transact online, and internet users. Information is a valuable and costly asset that must be presented, controlled and planned just like other valuable assets within an organization. This work is designed to provide a security mechanism using a computerized data encryption system, readable data is altered into unreadable form to prevent unauthorized access. Encryption is able to use powerful mathematical concept to create coded message that is virtually impossible to break. It is easy to encrypt a message on a simple personal computer so that the biggest computer in the world could not decipher without spending for more time on the problem that exists in the life span of the entire universe.
