Abstract
Provided is a technique for computing confidential values of a first plurality of pieces of data satisfying predetermined search conditions from a sequence of confidential values of N pieces of aligned data and confidential values of a query. A vector decomposition means for computing a share [[v]] of a vectorv(i=1, . . . α) having a length β satisfying predetermined conditions from a share [[v]] of an aligned vectorv having a length N, a first detection means for computing a share [[f]] of a vectorf having a length α satisfying predetermined conditions from the share [[v]], a partial vector computation means for computing a share [[a]] of a vectora having a length βγ satisfying predetermined conditions using the share [[v]] and the share [[f]], a second detection means for computing a share of [[b]] a vectorb having a length β satisfying predetermined conditions from the share [[a]], and an output computation means for computing a share of a search result vector from the share [[a]] using the share [[b]].
