Definition: Data Encryption is a phrase generally used by people to refer to a process of converting electronic communications (letters and values) into an unreadable form or code using an algorithm to scramble the real meaning of a message, transaction or other document. Doing so makes it possible to maintain confidentiality and business continuity. An organization's information security policies should be established that specify what encoding schemes are to be used.
Its Relevance: Protecting the confidentiality of information is vital to the continuous operations of a business. Safely conducting business and commerce using computers or over the Internet would, otherwise, be impossible. All measures that can be used to accomplish this task should be taken. Disguising the meaning of information is essential and should be included as an official part of information security policies.
