Abstract
Insertion of a watermark corresponding to the content of a file at the time of the printing of the file is made possible. Importance and/or confidentiality is defined per keyword in advance, and the watermark to be inserted is defined based thereon. At the time of the printing of the file, a keyword search within the file is performed, and the watermark to be inserted is automatically selected based on the search result (see FIG. 5).
Claims14
A printing management system for inserting watermark information into a file and printing the file, comprising:
- means which specifies a file to be printed from file storage means for storing a file;
- keyword storage means which stores a keyword which is a keyword that, if included in the file to be printed, signifies that watermark information is to be inserted into the file to be printed;
- watermark information storage means which stores the keyword and the watermark information in association;
- keyword search means which searches for the keyword included in the file to be printed by referring to the keyword storage means;
- watermark information acquisition means which acquires watermark information corresponding to the found keyword by comparing the found keyword with the keyword stored in the watermark information storage means;
- watermark insertion means which inserts the acquired watermark information into the file to be printed;
- printing means which prints the file to be printed into which the watermark information is inserted;
- hash calculation means;
- and
- file information registration means, wherein
- the watermark information storage means includes a keyword definition file that stores a watermark policy, which indicates the level of importance of the keyword, and the keyword in association, and a watermark definition file that stores the watermark policy and the watermark information in association,
- the watermark information acquisition means acquires the watermark policy corresponding to the found keyword, and acquires the watermark information corresponding to the acquired watermark policy,
- the hash calculation means calculates a hash of the file to be printed, and
- the file information registration means acquires from the keyword definition file the watermark policy corresponding to the found keyword, and registers in a hash policy file the acquired watermark policy and the calculated hash in association.

- and,
- printing, by printing means, the file to be printed into which the watermark information is inserted,
- wherein the watermark information storage means includes a keyword definition file for storing a watermark policy, which indicates the level of importance of the keyword, and the keyword in association, and a watermark definition file for storing the watermark policy and the watermark information in association, and
- wherein the watermark information acquisition means acquires the watermark policy corresponding to the found keyword, and acquires the watermark information corresponding to the acquired watermark policy,
- the printing management method further comprising the steps of:
- calculating, by hash calculation means, a hash of the file to be printed;
- and,
- acquiring, by file information registration means, from the keyword definition file the watermark policy corresponding to the found keyword, and registering in a hash policy file the acquired watermark policy and the calculated hash in association.
