Integrity is a security concept that ensures that data is accurate, complete and consistent, and that it has not been tampered with or modified in an unauthorized or unintended way. Integrity is important for e-commerce organizations to protect against erroneous purchases, as it can prevent data corruption, duplication, loss or manipulation that could affect the transactions or the records of the customers. Integrity can be achieved by using methods such as hashing, digital signatures, checksums, encryption and access control. Verified Reference:
