An information processing device using a primary function provided by a first server, includes a processor configured to receive, from the first server, access destination data effecting redirection to a second server providing a secondary function to be used by the primary function, send key data for encryption to the second server by adding the key data for encryption to the access destination data, transferring the access destination data to a browser, and redirecting the browser, and decrypt encrypted data based on at least a part of a response by the secondary function, the encrypted data being included in a response by the primary function, by using key data for decryption, the key data for decryption being adapted to the key data for encryption.

Information processing device, program, and information processing method

An anti-worm program allows a computer to execute control of communication suspected as worm communication, the program allowing the computer to execute: a communication information acquisition step that acquires communication information which is information concerning communication from a target source; and a communication control step that has a control amount calculation formula for calculating the control amount of the communication from the target source using the communication information and performs control of the communication from the target source based on the communication control amount obtained using the control amount calculation formula.

Anti-worm program, anti-worm apparatus, and anti-worm method

A management apparatus comprising memory to store owner information, dependence relationship information, and authorized user information are associated with file information identifying the secret file, an authorized user determination unit to determine whether a source user of the browse request is registered as the authorized user of the browse request file, a dependent file specifying unit to specify a dependent file having a dependence relationship with the browse request file by referring to the dependence relationship information when the source user is authorized; and a browse permission response transmitting unit to transmit the browse permission response to the source user based on whether or not the source user is registered as the authorized user of the dependent file by referring to the authorized user information.

Management apparatus

A first access policy is stored to provide information on a first distributee to which an electronic document is distributed, to which the first distributee is permitted to distribute the electronic document, and use rights that permit the second distributees to use the electronic document. Also stored is a distribution target information indicating the second distributees. When the first distributee requests permission to grant use rights to a specific distributee, the distribution target is consulted to confirm whether or not the specific distributee is included in the second distributees. A second access policy associating the specific distributee with the information on the use rights is then registered. When the specific distributee requests permission to use the electronic document, the second access policy is consulted to permit the specific distributee to use the electronic document.

Computer-readable recording medium storing access rights management program, access rights management apparatus, and access rights management method

A computer program, apparatus, and method for managing access to documents, capable of identifying the exact events of document access on the basis of given access logs even when access policies are modified in the middle of operations. Upon receipt of an access policy setup request from a first client, an access policy manager adds a new access policy to the access policy database or modifies an existing access policy in an access policy database according to the request. A policy log collector then stores the records of such a new access policy or modified existing access policy in a policy log database. Afterwards an access log collector receives an access log for the documentfrom the second clientand saves it in the access log database. When a third client issues a log request with a specific search keyword, a log searcher retrieves relevant policy log records and access log records that match with the specified search keyword.

Method, apparatus, and computer program for managing access to documents

A recording medium recording a network shutdown control program permitting suitable preventive measures to be taken. A detector monitors each network segment to be managed, and on detecting a communication fulfilling a predetermined condition, the detector generates a detection notification and sends the notification to a quarantine manager. On acquiring the detection notification generated by the detector of the local device or a detection notification generated by a remote network shutdown device, the quarantine manager generates a shutdown operation request in accordance with quarantine policy stored in a quarantine policy storage, and sends the request to a communication shutdown unit. In accordance with the shutdown operation request, the communication shutdown unit sets shutdown data identifying a target of shutdown and controls packets to be input to and output from the network segment so that the packets may be shut off or passed.

A contents utilization control apparatus includes an input unit for inputting a) contents with control module that consist of contents and a control module, and b) a license with control module that consists of a license prepared from contents utilization approval information and a control module. The control module in the contents with control module and the control module in the license with control module cooperate with each other to carry out a control relating to the utilization of the contents.

Method and apparatus for controlling contents utilization, and a computer product

A storage apparatus includes a key management unit for managing an individual key unique to the apparatus and a common key shared with other storage apparatuses, and an encryption unit for performing an encrypting process or verifying data for performing the encrypting process on electronic data stored in the apparatus to which the unit belongs using the individual key, and performing the encrypting process or verifying the data on the electronic data transmitted to or received from another apparatus using the common key. Thus, the apparatus communicates data using an applicable common key in a local environment and a global environment, appropriately manages a key in each environment, and guarantees the security of the electronic data.
