摘要： PROBLEM TO BE SOLVED: To perform statistic analysis in which privacy such as the identification information of a data source and the detailed contents of live data can be safeguarded for private dispersion database.SOLUTION: In compaction statistic, randomized data (hat) X and (hat) Y are acquired by separately subjecting data X and Y to first randomization. Subsequently, the randomized data (hat) X and (hat) Y are subjected to second randomization, thereby acquiring randomized data (tilde) X and (tilde) Y for a server and helper information Tx|x and Ty|y for a client. Here, T represents an experience distribution, and second randomization safeguards the privacy of the compaction statistic of the data X and Y. Next, the server acquires Tx, y. Lastly, a client acquires estimated (dots) Tx, y, by applying the helper information Tx|x and Ty|y in Tx, y. Here, "|" and "," between X and Y represent a conditioned distribution and a joined distribution respectively.

摘要： PROBLEM TO BE SOLVED: To provide a method for obtaining aggregate statistics while protecting the privacy of data from client data stored in a server.SOLUTION: At first, first data and second data independent in one or more clients are sampled such that the sampled data are obtained. Thus, aggregate statistics related to private data can be securely obtained. In this case, a sampling parameter is substantially smaller than the length of the data. The sampled data are encrypted such that the encrypted data are obtained, and then the encrypted data are connected. The connected encrypted data are randomized such that the randomized data are obtained. In an authorized third person processor, the joint distribution of the first data and the second data is estimated such that the difference privacy requirements of the first data and the second data are satisfied from the randomized encrypted data.
