US 7664829 B2Abstract
A document managing system is provided with a plurality of document managing apparatuses each configured to retrieve a document stored in a storage according to a document ID and to judge whether or not an operation with respect to the retrieved document is possible according to a user ID that is generated with respect to each document managing apparatus, and a user ID generating apparatus provided externally to the document managing apparatuses and configured to generate a common user ID that is used in common among each of the document managing apparatuses. Each document managing apparatus has an export and import part configured to export and import data of an arbitrary document and an access control list (ACL).
Accordingly, it is a general object of the present invention to provide a novel and useful document managing system, a document managing apparatus and a document managing method, in which the problems described above are suppressed.
FIG. 1 is a diagram showing a structure of an example of a conventional document managing system;
A description will be given of embodiments of the document managing system, the document managing apparatus and the document managing method according to the present invention, by referring to FIG. 2 and the subsequent figures.
FIG. 2 is a diagram showing a structure of a first embodiment of the document managing system according to the present invention. The document managing system shown in FIG. 2 has a first document managing apparatus 1 and a second document managing apparatus 2. Each of the first and second document managing apparatuses 1 and 2 may be a dedicated server apparatus for exclusive use or, an apparatus, such as a multi function peripheral (MFP), having functions other than the document managing function.
FIG. 4 is a diagram showing a screen for explaining an export operation. In FIG. 4, a document 41 that is to be exported is selected by a client software of the first document managing apparatus 1 or on an operation panel of an MFP, and an “Export” button in a pop-up menu 42 that is displayed is selected using a right-click of a mouse or the like, so as to instruct an export process. Then, a storage location of the export data is specified, and the execution of the export process is instructed. The export and import part 15 shown in FIG. 3 inputs the document ID, and retrieves from the document DB 13 the document data corresponding to the document ID. In addition, export and import part 15 obtains the ACL data corresponding to the document ID from the ACL table 14, and changes the document ID within the obtained ACL data to an indefinite value.
FIG. 5 is a diagram showing a screen for explaining an import operation. In FIG. 5, a logical storage location 51 of the document, such as a folder, for storing the imported document, is selected by a client software of the second document managing apparatus 2 or on an operation panel of an MFP, and an “Import” button 53 in a pop-up menu 52 that is displayed is selected using a right-click of a mouse or the like, so as to instruct an import process. Then, the import data is specified, and the execution of the import process is instructed. The export and import part 25 shown in FIG. 3 inputs the export data that includes the document data and the ACL data, registers the document data in the document DB 23, and obtains a new document ID. Next, the export and import part 25 updates the document ID within the ACL data using the new document ID, and registers the ACL data having the updated document ID in the ACL table 24.
FIG. 6 is a diagram showing a structure of a second embodiment of the document managing system according to the present invention. In FIG. 6, those parts that are the same as those corresponding parts in FIG. 2 are designated by the same reference numerals, and a description thereof will be omitted. In this second embodiment, the UID generating apparatus 3 is formed by a lightweight directory access protocol (LDAP) server, and the UID managing parts 11 and 21 of the first and second document managing apparatuses 1 and 2 are formed by user authentication for user directory (UAUD) parts in accordance therewith.
FIG. 10 is a diagram showing a structure of a third embodiment of the document managing system according to the present invention. In FIG. 10, those parts that are the same as those corresponding parts in FIG. 6 are designated by the same reference numerals, and a description thereof will be omitted. In FIG. 10, distinguish name (DN) compressing and expanding parts 16 and 26 are additionally provided in the first and second document managing apparatuses 1 and 2, respectively. The DN compressing and expanding part 16 compresses and expands the UID that is set in the ACL table 14, and the DN compressing and expanding part 26 compresses and expands the UID that is set in the ACL table 24. Otherwise, the structure of this third embodiment is the same as that of the second embodiment shown in FIG. 6.
FIG. 13 is a diagram showing a structure of a fourth embodiment of the document managing system according to the present invention. In FIG. 13, those parts that are the same as those corresponding parts in FIG. 6 are designated by the same reference numerals, and a description thereof will be omitted. In FIG. 13, hash tables 17 and 27 are additionally provided in the first and second document managing apparatuses 1 and 2, respectively. In this fourth embodiment, the FQDN that is obtained from the UID generating apparatus 3 is not used as it is when generating the UID, similarly as in the case of the third embodiment described above, and the FQDN is subjected to a hash process, so that the FQDN that can be accommodated within the ACL table even in the case of a relatively long FQDN. More particularly, the UID managing part 11 (or 21) of the document managing apparatus 1 (or 2) carries out the hash process with respect to the FQDN, and records a hash value and the original FQDN in correspondence with each other in the hash table 17 (or 27). In addition, the hash value (or hash code) of the FQDN data and a predetermined number of header (or leading) bytes of the FQDN data are set in the ACL table 14 (or 24) as a substitute UID.
