Integrity

In information security, data integrity means maintaining and assuring the accuracy and completeness of data over its entire life-cycle.This means that data cannot be modified in an unauthorized or undetected manner. This is not the same thing as referential integrity in databases, although it can be viewed as a special case of consistency as understood in the classic ACID model of transaction processing. Information security systems typically provide message integrity in addition to data confidentiality.
