Abstract
A data partition unit partitions character string data D into N pieces of element data w, w, . . . , wfrom a front to an end of the character string data D. A partial character string generation unit generates a set A={A, A, . . . , A} and an element A={(w), (ww), . . . , (ww. . . w)} of the set A where i=1, . . . , N, from the element data w, w, . . . , w. A position information assignment unit generates a set B={B, B, . . . , B} and an element B={(i, w, (i, ww), . . . , (i, ww. . . w)} of the set B by associating each of (w), (ww), . . . , (ww. . . w) which are components of the element Awith position information i. An encryption unit encrypts each of (i, w), (i, ww), . . . , (i, ww. . . w) which are components included in the element B.
