Integrity

Integrity =

Integrity involves maintaining the consistency, accuracy, and trustworthiness of data over its entire life cycle. Data must not be changed in transit, and steps must be taken to ensure that data cannot be altered by unauthorized people (for example, in a breach of confidentiality). In addition, some means must be in place to detect any changes in data that might occur as a result of non-human-caused events such as an electromagnetic pulse (EMP) or server crash. If an unexpected change occurs, a backup copy must be available to restore the affected data to its correct state.

Integrity of information refers to protecting information from being modified by unauthorized parties.

Information only has value if it is correct. Information that has been tampered with could prove costly. For example, if you were sending an online money transfer for 100 rupees , but the information was tampered in such a way that you actually sent 10,000 rupees, it could prove to be very costly for you.
