Integrity of data refers to the accuracy and consistency of data over its entire lifecycle, from creation to disposal. It ensures that the data is complete, accurate, and consistent and has not been tampered with or corrupted.

This can be achieved through various means such as implementing checksums, encryption, backups, and regular data validation. Ensuring the integrity of data is important for maintaining the reliability and trustworthiness of the information used in decision making and analysis, as well as to help prevent data breaches and other security incidents.
