Abstract
A system receives a document that includes new content and aged content, and compares the document with a prior version of the document that includes the aged content but not the new content. The system also separates the new content and the aged content based on the comparison, determines ages associated with the new content and the aged content, and determines whether the ages of the new content and the aged content are greater than or equal to an age threshold. The system further calculates a checksum of the document based on the aged content when the age of the aged content is greater than or equal to the age threshold, and the age of the new content is less than the age threshold, and stores the calculated checksum.
