An information processing apparatus includes an acquiring unit, an extraction unit, and a selection unit. The acquiring unit acquires, for multiple documents, candidates for elements representing characteristics of each of the multiple documents. The extraction unit extracts, from the candidates acquired by the acquiring unit, common elements common to two or more of the multiple documents. The selection unit extracts, from the multiple documents, a document including two or more common elements among the common elements, and determines the two or more common elements included in the extracted document to be elements representing characteristics of the document.

An image processing apparatus for providing at least a service to a service requestor receives a service execution request and authentication information of a service requestor from the service requestor and issues a request for authenticating the service requestor to an authentication service. Also, the image processing apparatus executes the requested service based on an authentication result transmitted from the authentication service. Further, the image processing apparatus manages an execution state of the executed service and an authentication state of the service requestor by associating the execution state with the authentication state.

An information processing apparatus includes a first acquiring unit, an addition unit, a second acquiring unit, and an extraction unit. The first acquiring unit acquires a first group of elements included in a first image generated by reading a document. The addition unit generates multiple second images by adding noises that differ from each other to the first image. The second acquiring unit acquires second groups of elements included in the respective multiple second images. The extraction unit extracts an element representing characteristics of the document from the first group of elements in accordance with the degrees of similarity between elements included in the first group of elements and elements included in the multiple second groups of elements.

In an information processing apparatus, object data based on a part of, e.g., a scan image is extracted and the extracted object data is stored in relation to attribute information of the relevant object data. The object data correlated to the attribute information, which matches with a search condition input by a user, is searched for, and the object data found through the search is merged to another object data depending on a characteristic of the user. The merged object data are displayed as a search result. In such a control process, different search results are displayed when users having different user characteristics input the same search condition.

An image processing apparatus for providing at least a service to a service requester receives a service execution request and authentication information of a service requester from the service requester and issues a request for authenticating the service requester to an authentication service. Also, the image processing apparatus executes the requested service based on an authentication result transmitted from the authentication service. Further, the image processing apparatus manages an execution state of the executed service and an authentication state of the service requestor by associating the execution state with the authentication state.

An information processing apparatus which enables reduction of the capacity of a data server. An intermediate server receives audit information concerning a job executed by an MFP or PC. The intermediate server registers at least one of attribute information and content information contained in the received audit information, in the data server. A registration processing determination section of the intermediate server determines a type of the job which the received audit information concerns. The section causes a job information and content information registration section to register the attribute information and the content information contained in the received audit information in the data server, or a content information registration section to register the content information in the data server without registering the attribute information therein.

When an image processing apparatus is newly installed, an access control request is issued from the image processing apparatus to a control apparatus at step S. Then at step S, regarding the image processing apparatus that has issued the access control request, an access control table to control access to functions of the image processing apparatus is automatically generated and registered in the control apparatus. In the control apparatus, access control is managed for each function of the image processing apparatus based on the registered access control table.

This invention has as its object to attain strong security and to implement network solutions with high convenience and simplicity with low cost upon providing Web services. To this end, an information processing apparatus according to this invention has the following arrangement. That is, an information processing apparatus () which includes a plurality of Web services (and the like) and a plurality of authentication/authorization services (and the like), is characterized by having an XML script unit () which holds an XML script () that describes association between information pertaining to respective Web services and information pertaining to the authentication/authorization services that execute authentication processing upon providing the respective Web services, and an arbitration service () which determines information pertaining to the authentication/authorization service described in association with the Web service requested by the user, and in that when the user is authenticated using the determined authentication/authorization service, the Web service requested by the user is provided.

Information processing apparatus, information processing method, program, and storage medium

An encrypted communication system according to the present invention comprises an authentication server in which a user password and an encryption key of a server were registered, a client involved in utilization by a user, and a server providing a service. According to the encrypted communication system, shared credentials for the client and the server to conduct encrypted communication are generated separately by the authentication server and the client based on mutually shared information, a ticket is generated in which the credentials that were generated by the authentication server are encrypted with the encryption key by the authentication server, and the client encrypts information to be sent using the credentials generated by the client and attaches the ticket that was acquired from the authentication server to the encrypted information to send the encrypted information and the ticket to the server.

Encrypted communication method and system

In a secured printing system including an information processing apparatus and a printer, when the information processing apparatus issues a print job in a suspended state to the printer, the printer having accepted the print job suspends and holds the print job until release of suspension of job is instructed, and returns job designation information peculiar to the accepted print job to the information processing apparatus. The information processing apparatus writes the job designation information returned from the printer in a detachable storage medium. The printer reads out the job designation information from the detachable storage medium, in which the job designation information is written, and, then, releases the suspended state of the corresponding print job.

Secured printing system

A secure communication method is performed in a system including a terminal device and an authentication server. The terminal device has at least one service process supplying a service to other terminal devices and a user authentication process performing authentication of a user, which processes run on the terminal device. The authentication server has an encryption key of the service process, registered therein in advance. The secure communication method includes the steps of generating a secret key used for achieving secure communication between the service process and the user authentication process by the authentication server, the generation being performed independently of the user authentication process; and encrypting the generated secret key with the encryption key of the service process to transmit the encrypted secret key to the service process by the authentication server.
