Crime prevention

Mizuho, as part of its social responsibility as a bank, is working aggressively to implement a wide range of measures against money laundering, terrorist financing, and losses as a result of illicit deposit withdrawals using cash cards (ATM cards), Internet banking, etc. and bank transfer fraud.

Efforts to prevent money laundering, etc.

In response to an increase in international demands for anti–money laundering and counter–terrorist financing measures in recent years, the Group is positioning the implementation of measures for anti–money laundering, counter–terrorist financing, and preventing other kinds of crimes as a top management priority. We are striving to prevent financial crimes through such activities as those to ensure that each branch thoroughly confirms requisite items based on applicable laws and regulations when new accounts are opened and through the establishment of specialized units that undertake the systematic monitoring of transactions that are improper, suspicious, or otherwise potentially problematic.

Initiatives to prevent losses as a result of illicit deposit withdrawals

Transition from regular cash cards (ATM cards) to smart IC cards

Mizuho Bank has substantially expanded its lineup of IC cash cards (ATM cards), including Mizuho Mileage Club Card and is actively issuing IC cash cards (ATM cards), which are considered more difficult to counterfeit than conventional magnetic stripe cards.

Biometric authentication via finger vein patterns

Mizuho Bank has adopted a biometric authentication system that identifies customers based on data of their vein patterns, which differ from one individual to another. To encourage a wider range of customers to use biometrics, Mizuho has installed in all the ATM areas, ATMs which have this identification feature.

Internet banking

Recently, there has been an increase in losses as a result of illicit deposit withdrawals using Internet banking through the use of computer viruses.

For individual customers, Mizuho Bank has introduced a transaction authentication function*1 and an e–mail method*2 both of which involve the use of a one–time password. In addition, Mizuho Bank is working to provide its customers greater peace of mind through measures such as monitoring banking activity 24 hours a day, 365 days a year to detect suspicious transactions and offering antivirus software at no charge to its customers.

For corporate customers, Mizuho Bank has introduced a function that separates the authority for approving bank transfers from the authority for preparing such transfer data. In addition to "double approval" function, where two people with approval authority must give approval for transactions, Mizuho Bank also provides anti–virus software at no charge to its customers, and has introduced IC cards for electronic certificate and one–time passwords. The aim of undertaking these measures is to strengthen security and give customers greater peace of mind.

  • *1Transaction authentication function
    This is a strong security measure, and it is used for transfer to non–registered transfer destination.
    When you enter the account number of the transfer destination using the dedicated card or smart phone app, a one–time password will be issued. This one–time password and the transfer account number are linked, and confirmation of the transfer destination is achieved when specified by the customer. Illegal remittance due to illegal rewriting of the transfer destination or account information can be prevented.

  • *2E–mail method one–time password
    When transfers are to be made from customers' accounts to parties other than those already registered in the system, and the Mizuho Bank system judges that there is a possibility that some party other than the authorized person has accessed the system, Mizuho Bank sends an identification number to the customers' registered e–mail address. To implement transfers, this number must be input. This e–mail method has proved to be effective in preventing illicit deposit withdrawals.

Activities to prevent losses to customer due to bank transfer fraud

Recently the number of incidents where customers incur losses due to bank transfer fraud has been rising. Examples often mentioned are where the party with criminal intent calls a party at home, posing as his or her child or grandchild, and requests the party to hand over or transfer a certain amount of money to an account. In other cases, the caller poses as a police officer or employee of a bankers association and asks for cash or the cash card (ATM card) of a party being deceived. In other cases, the caller poses as an employee of the social health insurance organization, pretends to return medical expenses, and makes a party remit a fund. Another tactic is to pose as a brokerage, offer to sell bonds, pre–listed shares, etc., and cheat a party out of his or her money.

Mizuho Bank and Mizuho Trust & Banking are stepping up their activities to prevent these incidents by having bank branch employees say a word of warning as they monitor customers at teller windows and ATMs. Other activities are preparation of posters, flyers, website messages, ATM screen messages, etc. that warn customers about these deceptive practices. Also, at the time of opening an account, Mizuho Bank works to prevent the opening of accounts that can be abused for bank transfer fraud by checking the identity in line with laws and regulations and checking the purpose of opening the account.

At each of the branches of Mizuho Bank and Mizuho Trust & Banking, the above–mentioned activities are being continued to prevent such incidents in advance.
