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

1. A forensic system configured to acquire digital information recorded on a plurality of computers or a server to analyze the acquired digital information, the forensic system comprising:

at least one or more processors configured to operate as;

a digital information acquiring unit configured to acquire digital information containing digital document information composed of a plurality of document files, and to acquire user information about users using the plurality of computers or the server;

a recording unit configured to record therein the digital information acquired by the digital information acquiring unit;

a display unit configured to display the recorded digital information, a display response of the display unit controlled by collecting transmission and receiving information in a virtual client/server between a plurality of clients and a user interface server;

a user-specifying information setting unit configured to set user-specifying information showing which one of users contained in the user-specifying information each of the plurality of document files is related, and configured to cause the recording unit to record the set user-specifying information, via the display unit;

a user selecting unit configured to select at least one user via the display unit;

wherein the user-specifying information further sets ranking information showing a relative degree of relationship of a first user with a litigation and a relative degree of relationship of second user with the litigation, and

said recording unit further configured to record middle group data as target digital information in conjunction with a confirmation screen on the display unit in a database of the forensic system, said middle group data being controllable as a group, and wherein the confirmation screen displays case information as an uppermost data group, and is further configured to set a connection destination of a server corresponding to the recording unit based on user input, and to manage association between the server and the recording unit based on user input; and

a control unit, comprising;

a searching unit configured to search a document file from among the target digital information where the user-specifying information corresponding to the selected user was set, and said searching unit provides a search result of at least one document to be analyzed based on the relative degree of relationship of the users, and said device further includes an output unit to output the search result, and said searching unit analyzing the search result of the at least one document according to at least one of a kind of file and a time of possession of the search result;

a highlight display unit configured to highlight, on the display unit, a searched word or phrase;

a case management unit (A), which allows data management for each case;

a managing unit including an access right control unit configured to set one or more rights for each of a plurality of accounts associated with a browser,

wherein the one or more rights set by the managing unit includes an access right for each case, a browsing-only right, and a manager right associated with the browser;

a free-design tag unit, which allows search for material provided with one evaluation or a plurality of evaluations as additional information based on the evaluation(s);

a free-input comment column including a comment column in which any number of characters can be inputted;

a case management unit (B), which allows display of the number of review-completed documents;

a digital document extracting unit configured to select a kind of file to be searched;

a data converting unit configured to preserve a selected file as a separate file; and

a plurality of additional information setting units configured to set additional information showing whether or not the searched document file is related with the litigation, wherein the additional information includes one of a first tag indicating that the searched document file is related with the litigation, a second tag indicating that the searched document file is potentially related with the litigation, and a third tag indicating that the searched document file is not related with the litigation, wherein the plurality of additional information setting units may simultaneously receive additional setting information from a plurality of users while evaluating digital document information.

2. The forensic system according to claim 1, wherein said control unit further comprises an e-mail family browsing processing unit, which allows collective browsing of an e-mail family.

3. The forensic system according to claim 1, wherein said control unit further comprises an e-mail threading unit, which displays e-mail threads collectively.

4. The forensic system according to claim 1, wherein said control unit further comprises a mail analysis display unit, which displays transmissions and receptions of mails graphically.
