JPH09274531A - Password input system for changing arrangement of numbers or symbols - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily input a password without stealing a glance at the password from the third person in the case of inputting the password for a burglar system to be locked/unlocked by inputting the password. SOLUTION: Concerning this password input system, a password input device or an input display part is changed and an input position is changed at every designated number of times. Thus, since the pushing position of an input button or the like is changed, the third person can not specify which number is inputted from the input position. Therefore, the password number is not embezzled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input system such as a secret code. Arrangement of input numbers and symbols in a security device that locks and unlocks by inputting a secret code is changed each time a specified number of times is input. As a result, the position where the input button or the like is pressed changes, and it becomes impossible for a third party to specify from the input position which number is being input. Therefore, the personal identification number cannot be stolen.

[0002]

2. Description of the Related Art Conventionally, numbers and the like are fixed in an ascending order or a descending order of an input portion of a security device for locking and unlocking by inputting a secret code. Other security devices include voiceprint identification,
Retina identification, fingerprint identification, handwriting pressure identification, etc.

[0003]

This has the following disadvantages. (A) In the personal identification identification method, the arrangement of the input device numbers and the like is fixed, and generally the identification is made by a four-digit number. It will be stolen. (B) For voiceprint identification, retina identification, fingerprint identification, handwriting pressure identification, etc., the device itself is complicated and large-scaled, and the cost is excessive, so that the place to use is limited. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems] Even if the same secret code is input by changing the secret code input device or the input display unit and changing the input position every designated number of times, the same finger movement does not occur. To do.

[0005]

[Operation] Since the input position changes, even if a third party steals the input position, the secret code will not be stolen. Furthermore, when a third party recognizes that the method of the present invention is used, it has the effect of alienating the third party's intent to steal, and damage can be prevented in advance.

[0006]

By using the present invention, since the input position changes, even if a third party steals the input position, the secret code or the like is not stolen. Further, when a third party recognizes that the method of the present invention is used, it has the effect of alienating the third party's intent to steal, and damage can be prevented in advance. Further, the present invention can be commercialized at a low cost by the existing technology, and can be downsized and easily added as an additional function to the current product.
