A deposit lockup financial system is provided to induce compromise by a safety tool to prevent a fraud case in advance, thereby increasing reliability about a counterpart person. A deposit lockup financial system(1) uses phone number authentication of a deposit person(1-A-1), a receiver phone number that the deposit person designates(1-A-2) and a secret number(1-A-3) as a safety tool of the deposit person based on use of the deposit person. If the transaction does not succeed, the deposit person does not let the receiver know the secret number and returns the deposit back according to predetermined standards of the deposit lockup financial system. The deposit is frozen as soon as the receiver performs deposit check through the receiver phone number. The receiver waits for a transaction result of the deposit person and the receiver. |
