First masked data is generated by masking registration target data by using the second code, and the first masked data is registered in a database. A third code is generated from a second random number by using the first error correction encoding method. Second masked data is generated by masking matching target data by using the third code. Synthesized data is generated by synthesizing the second masked data and the first masked data registered in the database, and the synthesized data is decoded in accordance with the first error correction encoding method and the second error correction encoding method.
