Outline of Final Research Achievements

On the cloud storages for personal use, there are several risks about the stored data such as steal, loss, falsification and leak. In this research, in order to avoid such risks, we develop a software such that it divides data to multiple shares by using the secret sharing scheme and uploads them to different multiple cloud storages, and also evaluate the performance of it. The developed software is useful for applications which require high security, such as the password managers. We also develop the password-protected secret sharing schemes which are enhanced schemes of secret sharing schemes.
