Abstract:
A method to allow programs running within the application space of a device with a secure processor and a trusted computing base to flexibly use certificates that describe the required system state. An information processing device including PSC database (1112), Component and PSC Map (1202), and OS support (1200).
Abstract:
A method to allow a device to boot in a secure fashion, even though some of the components within the secure device's firmware may not be present, not correctly authorized, or not correctly operating.
Abstract:
A semiconductor memory card stores a plurality of audio objects (AOBs) that compose a plurality of tracks and playlist information showing a reproduction order for the tracks. The semiconductor memory card also stores, as resume information (PLMG_RSM_PL), (1) a Playlist_Number showing which playlist information was used the last time playback was performed for the semiconductor memory card, (2) a Track_Number showing the last track to be played back, and (3) a Playback_Time showing a position at which where playback was stopped as a time expressed in relation to the start of the track.
Abstract:
An audio stream is divided into a plurality of audio object (AOB) files that are recorded having each been encrypted using a different encryption key. At least one piece of track management information (TKI) is provided corresponding to each track. Playlist information (PLI) assigns a playback position in a playback order to each track when a plurality of tracks are to be played back one after the other.
Abstract:
patente de invenção: "sistema e método de gerenciamento de reprodução de dados de áudio e aparelho de edição e meio de gravação". um aparelho de gerenciamento (fig. 1) armazena pares de conteúdos com direitos autorais e números de "check-outs" permitidas. ao ser requisitado para executar a "check-out" em relação a um cartão de memória semicondutora, o aparelho de gerenciamento grava um objeto de áudio (aob) correspondendo a um conteúdo no cartão de memória semicondutora, designa um id de conteúdo para o aob e decrementa um número correspondente de "check-outs" permitidas. um aparelho de edição e de reprodução edita o aob e designa um id de conteúdo, que é o mesmo que o id de conteúdo do aob original, para cada novo aob obtido pela edição. um armazenamento local mantém a informação de histórico incluindo um id do meio e o id de conteúdo designado para o aob original. quando sendo requisitado para executar a verificação de entrada para o cartão de memória semicondutora, o aparelho de gerenciamento coloca em um estado não-reproduzível o aob designado com um id de conteúdo que é o mesmo que o id de conteúdo na informação de histórico e incrementa o número de "check-outs" permitidas.
Abstract:
A data processing apparatus controls execution of debugging of a program performed by a debugger. The program includes a verification value used for judgment on whether to permit the debugging, and an access control list that shows whether to permit an access to each of parts constituting the program. The data processing apparatus acquires a debugger ID of the debugger from the debugger, and the verification value and the access control list included in the program. The data processing apparatus judges whether to permit the debugging, according to the result of comparison between the debugger ID and the verification value. The data processing apparatus permits an access to a part of the program to be debugged when the access control list shows that the access is permitted. The data processing apparatus does not permit the access to the part when the access control list shows that the access is not permitted.
Abstract:
An information processing terminal (40) includes: a network control unit (250); an installation control unit (260); a process control unit (200) for starting up an application and establishing cooperation among applications including the application; an access-history map updating unit (290) for updating an access-history map (281) which represents history information on an access relationship among the applications when a request is made to start up the application or to establish cooperation among the applications; and an unauthorized-cooperation-of-applications control unit (220) for (i) determining whether or not an unauthorized cooperation, which is directed at sensitive information kept secret, is established among the applications with reference to information obtained from the access-history map (281) and an application authorizing list (271), and (ii) controlling execution of the application using an application execution control technique in the case where a result of the determination shows that the unauthorized cooperation is established.
Abstract:
A License Management Apparatus, see FIG. 2. Each Audio Object (AOB) is put in correspondence with a Migrate Permission Flag (MPF) which is set to ON to show that a migration procedure is permitted. When a Right Management Information (RMI) does not exist for an AOB the MPF is set to OFF to show that a migration procedure is not permitted.
