Data processing device

Abstract

Data held by a first terminal can be used in a second terminal even after the first terminal has become disabled to be accessed from outside. When the first terminal (100a) detects an event which disables access to the first terminal from outside, the first terminal (100a) transmits the data held by it to another device (200) which can be accessed from outside. A second terminal (100b) which intends to acquire and utilize the data acquires the data from the device (200) and utilizes it.

Description

technical field [0001] The present invention relates to a data processing device in a system in which data can be moved between a plurality of data processing devices. Background technique [0002] In recent years, content distribution services have been started. This service transmits digital content such as music, video, and games, and value data (hereinafter referred to as "data") for the right to use the content to a data processing device through a network such as the Internet, digital broadcasting, or packaged media. [0003] A user wishes to use data acquired through a content distribution service in a data processing device convenient to the user. On the other hand, regarding the obtained data, it is often not allowed to be used simultaneously by a plurality of data processing apparatuses from the viewpoint of copyright protection, and it is often not allowed to copy the data. Therefore, there is a need for a data processing device that moves data between a p...

Problems solved by technology

However, when the other device T2 cannot be accessed from the outside, the device T1 cannot obtain the usable period P2

In other words, there is a problem that when a certain device is allowed to use data, if the device cannot be accessed from the outside due to power off or the like, all devices including the device cannot use the data.
