A representative entity is selected that is representative of the entities owning data of the type. Data of each of the representative entity and a target entity is encrypted and the encrypted data is exchanged between the entities. Each piece of the encrypted data that the target entity has obtained is re-encrypted by using its own encryption key to obtain data , and the encrypted data that the representative entity has obtained is re-encrypted by using its own encryption key to obtain data .
