Abstract: PURPOSE: A mobile device and information display method thereof are provided to effectively use an AR(Augmented Reality) method using diverse mapping information stored in a mobile device. CONSTITUTION: A display unit(120) displays a street view captured by a capturing unit as a three dimensional view. A storage unit(150) stores mapping information. A GUI(Graphic User Interface) processing unit(140) detects mapping information corresponding to the street view and maps the three dimensional GUI of the detected mapping information on the street view according to a relative location relationship between the mapping information. A control unit(130) controls the display state of the three dimensional GUI by maintaining the relative location relationship between the mapping information.

Abstract: A method for providing contents usage restriction data, an apparatus therefor and recording medium are provided to generate separated regulation data by using a DBMS based language for efficiently managing usage regulation of contents. A contents play device produces a first regulation data based on the data structure of DBMS(Data Base Management System)(310). The first regulation data is the combination of regulations for controlling usage restriction condition data. The contents play device produces a second regulation data(320). The second regulation data is the combination of the regulation for accessing usage restriction condition data through the first regulation data. The first regulation shows data record about usage restriction condition data in terms of a table format defined with data construct of DBMS.

Abstract: A method and a system for performing mutual authentication between devices by using an intermediary module are provided to keep high security in mutual authentication between host and mobile devices by checking validity of a certificate from a CA(Certificate Authority) before verification of a sign value and separately verifying the sign value with the intermediary module. An interface(310) transfers various kinds of key information between a device storing a certificate received from a CA and a host device, and receives an updated certificate revocation list from the CA. A key storing part(320) stores a first partial private key divided from a first private key stored in the device and a second partial private key divided from a second private key stored in the host device. A controller(340) determines validity of a unique ID by receiving the unique ID/random number, which are detected from the certificate, for the device and the host device from the device. An electronic signer(330) generates first and second partial sign value s by using the first and second partial private keys when the unique ID is valid.

Abstract: A conditional decoding method of contents and an apparatus thereof are provided to control an access for contents as a content unit by determining whether a contents key is revoked and selectively decoding the encoded contents using the contents key based on the determination result. A conditional decoding method of contents includes the steps of: receiving at least one of the contents key check data for checking a set of unrevoked contents key or the revocation of the contents key(310); determining whether a contents key for encoding and/or decoding the contents is revoked(320); selectively decoding the encoded contents using the contents key based on the determination result(330). The step of determining the revocation of the contents key includes the step of determining whether the contents key is revoked based on the inclusion state of the contents key for a set of the unrevoked contents.
