摘要

The random number generation unit (404) generates a plurality of random numbers from the plurality of seeds. The data disturbance unit (405) conceals the data to be concealed to be concealed using the plurality of random numbers generated by the random number generation unit (404). The transmitting unit (406) transmits the concealed data, which is the data to be concealed, concealed by the data disturbing unit (405) to the data analysis device, and after transmitting the concealed data to the data analysis device, a plurality of seeds are transmitted.
