摘要:
There is provided a document management server including a receiving unit that receives from a client a request and a first ID representing a document, an ID processing unit that issues, when an operation is performed on the document, a second ID, and records a derivation relationship having the second ID as a child of the first ID, a base node setting unit that sets a base node to indicate a division of a user among a node group in the derivation relationship, a document associating unit that associates related data of the document registered by an operation corresponding to a descendent node of a base node to the base node, and a document provider unit that provides, when receiving a user request for a digital document, detects a base node by tracing the derivation relationship from an ID accompanying the request to the root node, and provides the requested document based on related data associated to the detected base node.

There is provided a document management server including a receiving unit that receives an access request and a first ID representing a document to be an object of the access request, an ID processing unit that issues, when an operation is performed on the document in response to the access request, a second ID corresponding to the operation, and records a derivation relationship having the second ID as a child of the first ID, an attribute recording unit that records attribute information relating to the operation by association with the first ID or the second ID, and a response data provider unit that provides, when the document is provided to the client in response to the access request, response data including attribute information associated with at least one ID appearing in a path from the received ID accompanying the access request to a root of a derivation relationship.

A system includes an image formation apparatus, an image retrieval server, and image storage servers, and a network for connecting them. The image formation apparatus forms an image based on image data, records the image data in a predetermined storing location on the image storage servers, converts the image data under a predetermined rule to generate an image identification information as a key in order to read the image data from the storing location, and outputs the image identification information. Upon reception of an image data retrieval request together with an image identification information, the image retrieval server determines that the image data whose result of conversion under the predetermined rule is equal to the image identification information, among at least one image data stored in a predetermined storing location on the image storage servers, is the image data to be retrieved, and outputs its information.

An electronic ticket system for virtually preventing forgery, copying and other unauthorized uses of electronic tickets; for proving to a third party the contents of an electronic ticket contested between a user and an issuing party; and for protecting users' anonymity upon ticket use. The system comprises a ticket creating and issuing device, a ticket proving device, and a ticket verification device. A ticket creating unit in the ticket creating and issuing device creates specifications of a ticket representing a predetermined service or product in response to a ticket creating request. A ticket issuing unit of the ticket creating and issuing device, in reply to a ticket issuing request, issues the corresponding ticket using as input a ticket identifier, a proving identifier, a ticket specification identifier, and ticket added information. The ticket proving device gets a ticket issued by the ticket issuing unit and communicates with the ticket verification device to prove the possession of the ticket. The ticket verification device has a ticket verifying procedure and, on getting the ticket identifier created by the ticket creating unit, communicates with the ticket proving device to verify the ticket.

A document processing system includes a first acquisition section, a storage section, a second acquisition section and a data processor. The first acquisition section acquires a position specified by a user in an actual document. The storage section stores layout data of the document and content data of the document associated with the layout data. The second acquisition section acquires data in the specified position from the content data of the document stored in the storage section, based on the layout data stored in the storage section and the specified position. The data processor processes the data acquired by the second acquisition section.

The present invention allows even small-size verification devices to authenticate rights and qualifications without leaking authentication characteristic information to third parties. A ticket issuance device computes document private information &mgr; from a private function f of an interaction device owned by a user and document m to be transferred to the interaction device when generating interaction, and issues ticket t generated from authentication characteristic information x and the document private information &mgr; to the user. The interaction device, when document m is input, generates document private information &mgr; using a private function f specific to the interaction device, and performs interaction based on the document private information. The interaction comprises output of commitment r, input of challenge &khgr;, output of response &sgr;, and message M output. The user converts interaction (r, &khgr;, M, &sgr;) into interaction (r, &khgr;, M, s) using ticket t to perform Guillou-Quisquater authentication.

An electronic-document management system includes an acquisition unit, an edit unit, first and second storage units, a generation unit and an output unit. The acquisition unit acquires a target electronic document. The edit unit edits the acquired target electronic document. The first storage unit stores the target electronic document edited by the edit unit and a feature value of the edited target electronic document in association with each other. The generation unit generates meta-information of the edited target electronic document, which comprises a feature value of the edited target electronic document. The second storage unit stores the meta-information of the edited target electronic document and a feature value of the meta-information of the edited target electronic document in association with each other. The output unit outputs the feature value of the meta-information of the edited target electronic document as reference information of the edited target electronic document.
