| Non-repudiation protects individuals against later claims by an author of not having authored a particular document, a sender of not having transmitted a message, a receiver of not having received a message, or a signatory of not having signed a document. Non-repudiation services can be used to determine if information originated from an individual, or if an individual took specific actions (e.g., sending an email, signing a contract, approving a procurement request) or received specific information. Non-repudiation services are obtained by employing various techniques or mechanisms (e.g., digital signatures, digital message receipts).
When it comes to data review and data release, there must be a correlation between the data that is reviewed and the person who performs the review. If the reviewer is a human or if the review function is automated but separate from the release/transfer function, the application associates the identity of the reviewer of the information to be released with the information and the information label.
In the case of human reviews, this requirement provides appropriate organizational officials the means to identify who reviewed and released the information. In the case of automated reviews, this control enhancement helps ensure only approved review functions are employed.
