Abstract

The present invention makes it possible in encoded text checking to avoid the leaking of information related to the original plain text thereby ensuring safety. The system of the present invention is provided with: a means (103 in fig. 1) for generating first and second auxiliary data for verifying whether or not the Hamming distance of a plain text between a first encoded text in which input data is encoded and is recorded in a storage device and a second encoded text obtained by encoding input data of a target to be checked is equal to or less than a predetermined value; and means (402 403 in fig. 1) for taking the difference between the first encoded text recorded in the storage device and the second encoded text and determining using the first and second auxiliary data whether or not the Hamming distance of the plain text corresponding to the difference between the first encoded text and the second encoded text is equal to or less than the predetermined value.
