Development of the secure and economical disaster recovery technology by making use of widely distributed file backup technology

在当今高度信息化的社会中，大多数社会活动都是由电子数据基础设施支持的。然而，对于研究所重要档案数据的备份技术还没有建立起来。所需的技术应该以可承受的维护成本和高安全性来实现。我们利用广泛分布的PC、移动的手机、智能手机和云资源，结合分布式网络和流密码技术，开发了创新的文件备份技术。

In the present advanced information society, most of the social activities are supported by the electronic data infrastructure. However, the technology to back up institutes' important file data by any chances such as an unexpected disaster is not established yet. The required technology should be realized by an affordable maintenance cost and high security. We developed the innovative file backup technology by making use of widely distributed PCs, mobile phones, smart phones and the Cloud resources, with distributed networks and the stream cipher technology.
