Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: Movement histories of a vehicle are registered appropriately in a database. A point specification unit specifies a geographical base of a user as a point serving as a nucleus of behavior of the user. When the need arises to delete a movement history stored in the database, a deletion subject data determination unit specifies a movement history having a low degree of relatedness to the geographical base of the user. A data deletion unit then deletes the movement history specified by the deletion subject data determination unit from the database. As a result, behavior histories having a high utility value to the user are held preferentially in the database.
