DATA MANAGING APPARATUS AND A DATA MANAGING METHOD CAPABLE OF SAFELY STORING DATA AND EFFICIENTLY SEARCHING THE DATA

摘要

PURPOSE: A data managing apparatus and a data managing method are provided to protect the privacy of a user from being interrupted.;CONSTITUTION: An encryption part(108) encrypts the stored data of clients. An index generating part(110) generates a bucket-based index with respect to data in a bucket section of a pre-set length. A data managing part(104) transmits the encrypted data and the index to a server side data managing unit(200). The data managing part transmits cyclic bucket query information to the server side data managing unit. When the encrypted data corresponding to the query information is received from the server side data managing unit, the data managing part decodes the encrypted data.;COPYRIGHT KIPO 2012
