Patent number: 8713691Abstract: A system which implements a method for providing attribute data. A request is received from a user device via a network for a virtual ID token relating to attribute information pertaining to a subscriber associated with the user device. A data record including L attributes of the subscriber is read from a database, L being at least 2. The data record is provided to the user device via the network. A selection of M attributes of the L attributes is received from the user device via the network, M being less than L. A virtual record including the M attributes selected from the data record is generated, the virtual record including a virtual ID (VID) for identifying the virtual record. The generated virtual record is stored in the database. The virtual ID token is provided to the user device via the network, wherein the virtual ID token includes the VID.Type: GrantFiled: January 4, 2012Date of Patent: April 29, 2014Assignee: International Business Machines CorporationInventors: Yoshinobu Ishigaki, Masayuki Numao, Madoka Yuriyama, Yuji Watanabe

Patent number: 8463712Abstract: A system for enabling verification in traceability of a supply chain while maintaining confidentiality of private suppliers. A group signature is applied to an undisclosed supplier. The undisclosed supplier previously receives registration to the certificate authority device, and performs a group signature based on the certificate issued by the certificate authority device. A disclosed supplier and the undisclosed supplier sign and generate a signature chain when they ship parts. A verifier device receives a signature chain with products shipped from the supplier manager device, divides a signature of the disclosed supplier from a signature chain, and verifies the undisclosed supplier from the group signature. Identification of the undisclosed supplier is performed by a third-party auditor system requested to do so by the verifier device by using a group private key.Type: GrantFiled: August 5, 2009Date of Patent: June 11, 2013Assignee: International Business Machines CorporationInventors: Mika Saito, Yuji Watanabe, Madoka Yuriyama, Takeo Yoshizawa

Patent number: 7913093Abstract: A method and system for providing access to information on an article to which a tag is coupled. A local server reads the tag containing a virtual ID that includes an encryption of a bit string. The bit string includes an article ID containing a manufacturer ID. The local server is coupled to an ONS server, an ONS proxy server, and a PML server via a network. The local server sends to the ONS proxy server an ONS service request that includes the virtual ID and requests a network address of the PML server. The local server receives, from the ONS server, the network address of the PML server. The local server sends to the PML server, at the network address of the PML server, a PML information request that includes the virtual ID and requests article information. The local server receives, from the PML server, the article information.Type: GrantFiled: July 13, 2005Date of Patent: March 22, 2011Assignee: International Business Machines CorporationInventors: Yoshinobu Ishigaki, Masayuki Numao, Yuji Watanabe, Madoka Yuriyama, Takeo Yoshizawa

Patent number: 7836312Abstract: A technique for acquiring information. In response to receiving a request to read data stored in a database, said data is read from said database. In response to receiving a request to deliver particular data among said read data at a point in time when said particular data is to be used, it is determined whether said delivery request satisfies predetermined criteria. Said particular data is delivered in response to determining that said delivery request satisfies said predetermined criteria.Type: GrantFiled: August 4, 2004Date of Patent: November 16, 2010Assignee: International Business Machines CorporationInventors: Yoshinori Aoki, Keitaroh Dohmen, Masayuki Numao, Yuji Watanabe, Madoka Yuriyama

Patent number: 7769706Abstract: It is an object of the present invention to find out parts to be a highly possible cause of failure without searching all of part data of all of products. Dispersed parts data on a parts tree are sequentially accessed from a set of known failed products, and part attribute values each having a higher support in the faulty product are extracted. In this process, a subset of parts used in the faulty product is also obtained simultaneously. The part attribute values having higher supports and the subset of parts used in the faulty product are represented as a tree in which a parts type serves as a node. Next, an information gain of a rule that having the two part attribute values is a cause of failure is calculated on two part attribute values having higher supports on the tree of the parts type. This calculation is locally performed on a common parent part of two parts and parts having a certain information gain is outputted as a cause of failure.Type: GrantFiled: June 22, 2009Date of Patent: August 3, 2010Assignee: International Business Machines CorporationInventors: Fumihiko Kitayama, Hirofumi Matsuzawa, Masayuki Numao, Madoka Yuriyama
