  • Patent number: 10176436
    Abstract: A method and system are provided for estimating a skill level of a user regarding a software program executed by the user on a computer processing system. The software program has workbenches that each include commands corresponding thereto. The method includes creating at least one special command set for user skill level estimation by including the commands that exist in various ones of the workbenches and that are executed at least a predetermined percentage of times by the user and excluding the commands which are common to at least two of the workbenches. The method further includes creating partial command sequences from the commands in the at least one special command set. The method also includes determining frequent command execution patterns by applying pattern mining to the partial command sequences. The method additionally includes estimating the skill level of the user based on frequencies of the frequent command execution patterns.

  • Publication number: 20180307999
    Abstract: A method including receiving designation of an input node for which a node value is generated from collected data, an option node to which a node value is arbitrarily provided, and an estimation target node to be a target of a node value estimation, in a graph including nodes and directional edges; and identifying a directional edge for which a conditional probability is to be acquired to measure the node value of the estimation target node, from among the directional edges, by traversing a directional edge that can propagate an effect to a node value from the estimation target node. The identifying includes, for the option node, traversing both a directional edge that can propagate an effect if a node value is provided to the option node and a directional edge that can propagate an effect if a node value is not provided to the option node.

  • Publication number: 20170185907
    Abstract: A method is known for identifying a cause and effect relationship between events of equipment by using a Bayesian network, but it has been difficult to comprehensively gather events relating to people. Additionally, there is no known method for estimating the time at which other events occur between two or more events. Provided is an information processing apparatus including a target information obtaining section that obtains known event information relating to at least one known event that has occurred for a target; an information processing apparatus that obtains statistical data relating to events; and an event information generating section that generates unknown event information relating to an unknown event of the target, based on the statistical data and the known event information.

  • Patent number: 8811607
    Abstract: 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.

  • Patent number: 7792861
    Abstract: It is one object of the present invention to provide an access control system that employs 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. An access control system comprises: an access controller 200 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 500 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 200 determines whether or not access to the access control rule should be permitted.

  • Patent number: 6990585
    Abstract: 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.
