PROBLEM TO BE SOLVED: To provide an information processing unit configured to prevent occurrence of a situation in which an access right for a second document relating to a first document is made different from an access right for a fourth document relating to a third document.SOLUTION: First detection means of an information processing unit detects a second document relating to a first document on the basis of an operation history with respect to the first document. When the first document has shifted in phase, second detection means detects a third document, which is a document that has the same type as the first document and that has already completed in document life cycle. Pattern generation means generates an operation history pattern on the basis of the operation history of the third document. Calculation means calculates the degree of the difference between the pattern and the respective operation histories of the first document and the third document. Third detection means detects a fourth document relating to the third document on the basis of the operation history of the third document. Access right changing means changes an access right for the second document on the basis of an access right for the fourth document. |
