摘要: | 在現在資訊社會中,雲端儲存服務是路人皆知的方便服務,無論是影音娛樂、工作檔案、私人相片等,許多檔案都已在雲端中儲存,可是雲端公司是否會窺探使用者的隱私,對於使用者是個很大的問題,尤其現在資料探勘與機械學習如此的發達,難保雲端服務公司不會學習使用者的資訊。在不信任雲端公司的情況下,使用者如何自保資料的隱私權就是個重要的課題。
為了保護使用者的隱私,不僅應該把資料加密,並且在檔案名稱、大小,檔案儲存的結構、資料夾的子母關係都要盡量保護,所以在引入Blind Storage加上索引檔案引入,讓雲端儲存公司無法得知使用者的隱私。並且加上加解密同步,讓使用者能如同一般雲端儲存的同步應用程式,使得在保護隱私的同時不減少雲端儲存的方便性。 In modern Information Society, Cloud Storage Service is well-known service, many files such as entertainment media, work file, and personal photos are storage in Cloud Storage Service. However, whether the company of Cloud Storage Service will try to violate user privacy is an issue for service user. Moreover, Data Mining and Machine Learning is well-developed, which make user afraid of service company will try to learn the information from his account. When user does not trust the cloud server, we need to find a way to protect our own privacy. In order to protect user privacy, we should not only encrypt the data content but also protect the metadata. Then, we use Blind Storage with Index file to prevent server to learn information from data content and metadata. In addition, by using encrypt synchronization user can use blind storage just like normal Cloud Storage Service Application. Not only can protect user privacy but also keep it convenient to use. |
