Abstract: An alteration detection apparatus generates index information based on a document in a storage. The alteration detection apparatus acquires index information that is associated with information identifying a document. The alteration detection apparatus determines whether there is an alteration added to the acquired document based on a result of comparison between the generated index information and the acquired index information. The alteration detection apparatus detects, when there is an alteration, an altered part in the acquired document based on the result of comparison between the generated index information and the acquired index information.
