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 is 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).
In cryptography and information security in general, integrity refers to the validity of data. Integrity can be compromised through:

In cryptography and information security in general, integrity refers to the validity of data. Integrity can be compromised through:
- Malicious altering, such as an attacker altering an account number in a bank transaction, or forgery of an identity document.
- Accidental altering, such as a transmission error, or a hard disk crash.
- Programming errors that result in inconsistencies in the data.
Its one of the powerful feature offered by electronic signature scheme. Electronic signature is a well know scheme which is used for the protection of data. Thanks to you for explaining this main feature.
