To perform a smooth transaction while the deposit of a customer is securely kept at the time of a financial transaction such as a foreign exchange transaction.
Deposit data from the customer 10 is transferred not to a stock company 20 which actually preforms dealing order but to the account databases 31 and 41 of a maintenance trust organization 30 and a security trust organization 40, and maintenance/security trust are set. Actual dealing of the order is preformed within the range of security of security data D4 in a range of deposit data which is security-trust-set in the security trust organization 40. Namely, the deposit from the customer 10 is classified and kept not in the stock company 20 performing dealing order but in the maintenance trust organization 30 and the security trust organization 40, which are trust organizations. Thus, a risk where the deposit from the customer 10 and owned funds of the stock company 20 coexist can be reduced, and the deposit of the customer 10 is securely kept in the maintenance trust organization 30 and the security trust organization 40.
