Document Type and Number:
Japanese Patent JP2005535990
Kind Code:
A
Abstract:
A password system and a method for authenticating a user of such a password system are disclosed. The present invention provides a novel method for inputting a password which is capable of preventing a password from being revealed to others observing the course of inputting the password, and an improved password system which is capable of providing a user interface suitable to such a method for inputting a password. The user interface provides at least two symbol boards, and symbols arranged on the two symbol boards are matched by means of matching means provided to a user. At this time, the symbols matched for inputting the password and other different false symbols disguised as the symbols matched for inputting the password are matched simultaneously, whereby it is not possible for an observer to distinguish which of the symbol matching is the one for inputting the password.
