Integrity is a key element in recordkeeping. According to AS ISO 15489, integrity of documents means that they are complete and unaltered.
These words mirror s.11(3) of the Electronic Transactions Act 2000 (NSW) which notes that the integrity of information contained in a document is maintained if, and only if, the information has remained complete and unaltered, apart from:
(a) the addition of any endorsement, or
(b) any immaterial change, which arises in the normal course of communication, storage or display.
