  Abstract

Financial accidents such as password exposure of credit cards or bankbooks occur often when a password is inputted to ATM/CD(Automated Teller Machines and Cash Dispenser), so particular attention is required when inputting a password. This study suggested a method to input a password safely to prevent stealing a glance at a password in case of the use of ATM/CD. The method is that users input a password when numbers are randomly displayed and disappear not to notice the password even though someone is next to or behind the users. As methods to input a password safely, the study verified safety by dividing the methods into a test of shoulder surfing, an intuitive perspective, and a theoretical analysis. In addition, the result of implementation to apply the method to ATM/CD shows that a percentage of acquiring a password from the attack of shoulder surfing is found to be lower than an existing method, so password exposure can be prevented.
