Abstract:
Provided are an apparatus and method for managing identity information. The apparatus includes a contract detail manager managing details of an identity information sharing contract made between a user and an identity provider (IdP) wanting to provide identity information about the user, and details of an identity information sharing contract made between the user and an identity consumer (IdC) wanting to be provided with the identity information about the user, an IdP selector selecting an IdP capable of providing the identity information about the user based on the details of the sharing contract when a request for the identity information about the user is input from the IdC, and an information provider obtaining information according to the identity information request from the selected IdP, and providing the obtained information to the IdC. The apparatus and method can solve a problem that all of a user's identity information is provided to an IdC according to the user's comprehensive agreement.
Abstract:
A method of providing customized service with privacy security includes: requesting service information provided from a smart environment to a smart environment control system; once the service information is transmitted from the smart environment control system, generating schedule information by using the service information, user personal information, and schedule generation information; and transmitting a service command to the smart environment control system according to the schedule information.
Abstract:
A user authentication system using a personal identification number, includes a user terminal device for requesting issuance of a personal identification number from an authentication server, storing and displaying a personal identification number, and registering reference information used to permit verification of validity of the personal identification number on the authentication server. Further, the user authentication system includes an inquiry device for requesting verification of validity of the personal identification number from the authentication server, and receiving and displaying results of the verification. Furthermore, the user authentication system includes an authentication server for storing issuance information while issuing the personal identification number, determining whether to permit the verification of the validity of the personal identification number, if the inquiry device requests the verification of the validity, and replying with results of the verification, if it is determined that the verification of the validity is to be permitted.
Abstract:
A smart wallet service module includes: a management unit for installing, activating, and terminating a smart wallet service or receiving and managing a user's setting; a security unit for providing an authentication service through an authenticated certificate or electronic signature; a storage unit for storing data in a database of a mobile device and managing the stored data; and a functional unit connected to a storage medium inside the mobile device and providing a service related to electronic commerce or credit card issuing.
Abstract:
An apparatus for inputting a user password, includes an interface receiving a command. Further, the apparatus for inputting the user password includes a control unit setting a target based on the command from the interface, receiving and storing a password character, and determining that authentication is successes only when the set target and the password character are positioned at a same coordinate on a skin image. Furthermore, the apparatus for inputting the user password includes a display unit connected to the interface to display the skin image of the interface that is transmitted from the control unit.
Abstract:
A key tree construction and key distribution method for hierarchical role-based access control, includes: constructing a key tree including relationships between a hierarchical structure of role groups and data; performing encryption and decryption of data keys and role keys; and generating a key table, in which the data keys required to decrypt encrypted data and the role keys required to decrypt encrypted data keys are stored, with reference to the key tree. Further, the key tree construction and key distribution method for hierarchical role-based access control includes performing management such that a specific role group can obtain a data key by performing decryption based on its own role key by using both the key tree and the key table.
Abstract:
Disclosed herein is a method and apparatus for partially encoding/decoding data for a commitment service and a method of using encoded data. The apparatus includes an encoding/decoding module for encoding/decoding a database to be committed to a server using a private key of the user, obtained by accessing a key storage unit through a key management module which manages information about the private key of the user, stored in the key storage unit, and also encoding/decoding an SQL query required to use a DB committed to the server. The encoding/decoding module partially encodes/decodes one or more of table names, field names, and attribute values of the DB. In the present invention, the table names, field names, and field attribute values of the DB are partially encoded while the existing structure of the DB is maintained, and the partially encoded DB is committed to the server.
Abstract:
Disclosed is a method for retrieving a label in a portable terminal. The method includes obtaining a label image photographed through a camera, extracting characters included in the label image and recognizing the extracted characters, detecting at least one label including the recognized character from a label database including multiple labels and information on the multiple labels and constituting a preliminary label candidate group including said at least one label, detecting an image characteristic of the label image, detecting at least one label having an image characteristic, which is similar with the detected image characteristic, from the preliminary label candidate group, and constituting a final label candidate group, and providing each of said at least one label included in the final label candidate group and detailed information corresponding to each of said at least one label.
Abstract:
A disc centering device includes a base plate, a chuck which is installed on the base plate, a hub unit which is detachably engaged to the chuck and receives discs to be stacked, disc pushers which are slidably provided outside the hub unit and include corresponding pressure members which center the discs by pushing circumferences of the discs, and a driving unit which slides the disc pushers simultaneously. Accordingly, as the accuracy of centering the discs is improved, discs with data recorded thereon having a uniform quality can be obtained. Additionally, vibration of a rotation body can be minimized due to the simple configuration the disc centering device. Therefore, in view of the simplified maintenance and repair of the disc centering device, the productivity and manufacturability of HDDs can be improved.
Abstract:
A digital distribution management system and a contents distribution management method using the same are provided. The system is formed of a contents-user, a broker, a contents-owner, and a contents distributor. The broker receives a contents use fee from the contents-user, transmits a contract document for contents use to the contents-user, pays a loyalty to a contents-owner, pays a distribution fee to the contents distributor, and makes a contract for contents use. The contents-owner transmits use rights, i.e., Service Release (SR) information on corresponding contents of a proper contents-user making a contents use contract to the contents distributor and receives a corresponding loyalty through a broker. The contents distributor receives the SR information from the contents-owner, transmits the contents and a license on the contents information so that the proper contents-user can use the corresponding contents, and receives a corresponding distribution fee through the broker.
