摘要： It is one object of the present invention to use an access control process to evaluate under a specific condition an access permission request. An access control system 100 comprises a resource document 40 in which a policy description is stored; a policy evaluation module 10 for receiving an external request 110 for accessing the data file, for extracting, from the resource document 40, the policy description that is associated with target data for the access request 110, and for evaluating the policy description to determine whether or not the access request 110 is to be permitted; an enforcement function verification module 20 for, when an existing condition can not be evaluated using only the information included in the policy evaluation module 10, determining whether the condition can be evaluated or can be established; and an enforcement module 30 for evaluating or establishing the condition that, in accordance with the enforcement function verification module 20, can be evaluated or established.

摘要： The present invention provides access control methods, apparatus and systems that employ an access control rule and that does not distinguish between data and the access control rule, so that the same flexible access control that is available for the data can also be provided for the access control rule. In an example embodiment, an access control system comprises: an access controller for, in accordance with the access request, employing an access control rule defining an access right for the object to determine whether or not access to the object should be permitted; and an object storage unit for storing a set of access control rules as objects equivalent to common data objects, wherein, upon the receipt of a request to access an access control rule, the access controller determines whether or not access to the access control rule should be permitted.

摘要： A method and system for generating contexts of targets to estimate a high-order context. The system includes: a detection device including: a sensor for detecting a target; module for extracting the target and a primary context of the target based on data detected by the sensor; and module for encrypting the primary context with a key corresponding to the target; a storage device for recording encrypted primary context from the detection device; and a processing device including: module for receiving the encrypted primary context from the storage device; module for receiving the key corresponding to the target involved in the encrypted primary context; module for decrypting the encrypted primary context using received key; and module for estimating a high-order context using the decrypted primary context; where the processing device further includes a module for requesting the detection device to delete information on a key corresponding to a specific target.

摘要： The present invention provides digital signature techniques using an information terminal, such as a portable terminal, having limited calculation resources. In one embodiment, a signature demandant generates a document to be signed, and an agent receives this document. The agent generates summary text for this document, and transmits the summary text to a signatory, and the signatory displays the summary text using his or her information terminal. The signatory confirms the contents, employs a private key stored in his or her terminal to sign (encrypt) the summary text. The signatory thereafter transmits a signature value to the agent, who generates a signed document that includes the signature value. Finally, the signature demandant verifies (decrypts) the received signed document using the public key of the signatory and confirms the contents.
