Abstract

PURPOSE:To prevent an illicit access cause by the leakage of a password by registering previously not only the password but the character input interval. CONSTITUTION:A conincidence deciding device 6 decides the coincidence between the character input intervals of passwords as well as the coincidence between the passwords. A monitoring device 3 monitors the character input intervals as the time when a user inputs a password to a terminal equipment 2. Meanwhile the input character intervals are ciphered and registered previously by a registering device 7. Then the coincidence is decided by a coincidence deciding device 6 between the registered character input intervals and those of the password inputted by the user. Thus the grant to an illicit access caused by the leakage of the password only can be evaded.

Prior Art In this type of conventional system, it is possible to determine whether a user is a legitimate user by comparing input information of a user name and password with encrypted registration information registered in advance on the system side. The system identifies whether or not the access is permitted and makes decisions on whether to grant access.

Composition of the Invention The user identification system according to the present invention is a user identification system that allows access to an information processing system only after confirming that the password matches a pre-registered password in response to input of a password for identifying the user. The system comprises a registration means for registering in advance an input interval between characters of a character string constituting the password, a measurement means for measuring the input interval, and a registration interval between the measurement result and the registration means. and detecting means for detecting a match.

The figure is a system block diagram of an embodiment of the present invention. A user can access the computer system 1 via a terminal device 2 by inputting a password. The match determination device 5 determines whether the password input from the terminal device 2 to determine the validity of the user matches a registered password registered in the registration device 7 in advance. In this case, the registration device 7 is provided with a password registration section 8, in which the password is encrypted and registered in advance.

In the present invention, a match determining device 6 is provided which not only determines whether the password matches, but also determines whether the input interval between characters when entering the password matches. This input interval is monitored by the monitoring device 3, and when a user inputs a password on the terminal device 2, the character input interval at the time of input is monitored as time.

In the registration device 7, this input character interval is also encrypted and registered in advance, and the match determination device 6 compares and determines this registered manual interval with the character input interval of the password entered manually by the user. . The encryption device 4 encrypts the input password and the input character interval according to predetermined rules.

Here, the input character interval is the input interval between the first character and the second character, the input interval between the second character and the third character,..., the input interval between the nth character and the D+1st character. The human input intervals for each character are predetermined and registered, and when the password is actually entered, each character interval is entered in the predetermined manner.

As another example, a cursor may be displayed blinking on the display screen in synchronization with the system clock so that the character input interval can be grasped, or the second hand of a clock may be displayed. Furthermore, the character input interval may be notified to the user by audio information.
