    • The present invention is directed to an information processing system composed of plural information processing units adapted for mutually executing data communication, and for executing data processing in which communication data has been applied. The first entity A transmits error notification data on the basis of error detection to execute initial state return processing on the condition that data reception after error notification data has been transmitted is made, and the second entity B transmits error notification data on the basis of error detection to execute initial state return processing on the condition that transmit processing of error notification data is executed. Thus, the both entities A and B can return to the initial state in a manner synchronous with each other. As a result, it becomes possible to perform reliable error recovery and data processing restart.
    • 本发明涉及一种信息处理系统,其由适于相互执行数据通信的多个信息处理单元组成,并且用于执行其中应用了通信数据的数据处理。 第一实体A基于错误检测发送错误通知数据,以便在发送错误通知数据之后的数据接收的条件下执行初始状态返回处理,并且第二实体B基于错误发送错误通知数据 在执行错误通知数据的发送处理的条件下执行初始状态返回处理的检测。 因此,两个实体A和B可以以彼此同步的方式返回到初始状态。 结果,可以进行可靠的错误恢复和重新开始数据处理。

    • Provided is an authentication system capable of identifying a cause of a failure when authentication fails. A data structure of data to be authenticated has a header authentication data area (D2), and an authentication data area (D4) in addition to a header area (D1) and a data area (D3). The header authentication data area (D2) authenticates validity of the header area (D1), and the authentication data area (D4) authenticates the validity of the header authentication header area (D2) and the data area (D3). Since two kinds of authentication are carried out, the cause of the failure in authentication can be identified easily when authentication is failed.

    • A management server receives first user identification information and designation information for designating a service which are sent from a user terminal; detects specific information corresponding to a service provider which provides the desired service from a database containing specific information uniquely assigned to each service provider; generates second user identification information based on the detected specific information and the first user identification information; and then transmits the second user identification information to the user terminal. Using the second user identification information, the user terminal accesses the server of the service provider providing the desiring service. This prevents important information such as device IDs from being used when a user receives a service through a network from a service provider other than device manufacturers, and relieves the burden on such service provider upon providing a service.
    • 管理服务器接收从用户终端发送的用于指定服务的第一用户标识信息和指定信息; 从包含唯一分配给每个服务提供商的特定信息的数据库检测与提供期望服务的服务提供商对应的特定信息; 基于检测到的特定信息和第一用户识别信息生成第二用户识别信息; 然后将第二用户识别信息发送给用户终端。 使用第二用户识别信息,用户终端访问提供期望服务的服务提供商的服务器。 当用户通过网络从设备制造商以外的服务提供商接收到服务时,这样可防止诸如设备ID之类的重要信息,并且在提供服务时减轻对该服务提供商的负担。

    • To provide a recording medium on which an entire piece of decryption information that is required to be highly secure is recorded while being kept secure even when it is larger in data size than the storage capacity of an area originally intended for recording it. A recording medium in which encrypted content that has been encrypted and decryption information for the decryption of the encrypted content are recorded in two areas of different security levels. Decryption information B which is a portion of the decryption information is recorded in an area L of a relatively higher security level. The encrypted content and decryption information C which is the remainder of the decryption information that has been encrypted are recorded in an area D of a relatively lower security level. The decryption information B recorded in the area L includes information indicating the location where the decryption information C is recorded and information for the decryption of the remainder.
    • 为了提供一种记录介质,在该记录介质上记录需要高度安全的整个解密信息,即使当数据尺寸大于原始用于记录的区域的存储容量时,也能保持安全。 其中已经加密的加密内容和用于解密加密内容的解密信息被记录在不同安全级别的两个区域中的记录介质。 作为解密信息的一部分的解密信息B被记录在相对较高安全级别的区域L中。 作为已被加密的解密信息的其余部分的加密内容和解密信息C被记录在相对较低安全级别的区域D中。 记录在区域L中的解密信息B包括指示解密信息C被记录的位置的信息和用于其余部分的解密的信息。
