Abstract

Embodiments of the inventive concept can extract digital document information related with a specific individual to achieve a work load reduction associated with evidentiary material preparation for litigation. Recorded digital information can be displayed and user-specifying information can be set for each of a plurality of document files. The user-specifying information shows which user contained in user information one or more document files is related with. A recording unit can record the set user-specifying information. At least one user is selected, and a document file where user-specifying information which corresponds to the selected user was set is searched. Additional information showing whether or not the searched document file is related with the litigation is set via a display unit. A document file which is related with litigation is outputted based on the additional information.

Claims
