| Research Abstract |
We propose a data archive scheme that divides the input data into many tiny fragments and distributes each fragment across multiple storages chosen at random. In this research, we have proved that the archived data generated by our scheme can not be distinguished from randomly generated data from the probability and statistical point of view. Also, we have developed a prototype of the scheme, and have verified that the scheme is efficient sufficiently for the practical use. We expect that this sc heme is useful to realize inexpensive back-up services in the cloud computing.
