Abstract
In a policy-change input unit (10), a policy recalculation unit (133) compares, upon occurring of a change request of a privacy policy from a user, an existing policy against an updating policy, recalculates a transmission policy to be transmitted to other providers based on the result of comparison, and transmits the recalculated policy to the other policy. The policy recalculation unit (133) transmits a deletion request of personal information to another provider by using a deletion-request creation unit, upon judging that the another provider cannot use the personal information due to the change of privacy policy.
