  A document editing unit that divides the document data into specific information data composed of the specific information extracted by the specific information extraction unit, and document data without specific information obtained by removing the specific information from the document data;
  A document storage unit that stores the specific information data generated by being divided by the document editing unit in association with the document data without specific information;
  An image processing apparatus.

An information transfer unit that transfers the specific information data generated by being divided by the document editing unit to an external storage device;
The image processing apparatus according to claim 1.

A storage information generation unit configured to generate storage information indicating an association between the document data without specific information stored in the document storage unit and the specific information data transferred to the storage device;
The image processing apparatus according to claim 2.

A specific information encryption unit that encrypts the specific information data generated by being divided by the document editing unit;
The information transfer unit transfers the specific information data encrypted by the specific information encryption unit to the storage device.
