Data integrity is a term used in computer science and telecommunications that can mean ensuring data is "whole" or complete, the condition in which data are identically maintained during any operation (such as transfer, storage or retrieval), the preservation of data for their intended use, or, relative to specified operations, the a priori expectation of data quality.

Put simply, data integrity is the assurance that data is consistent and correct. Often such integrity is ensured by use of a number referred to as a Message Integrity Code (MIC) or Message Authentication Code (MAC).
