JPH11229688A - Key as locking-unlocking and start-stop device by hand-writing input - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a device capable of solving all of inconvenience in carrying, low safety, the trouble of abrasion after a fixed period passes, damage by the quality of a material and a storage space or low security in conventional keys. SOLUTION: When a specific character, sign or graphic is set beforehand in devices 2, 4 and a cipher is input by the finger of a hand by an input device 1, the cipher is digitized in the device 1, and compared with beforehand set data and discriminated, the locking and release of doors and the start and stop, etc., of systems are executed and a function as the key is fulfilled. Accordingly, since the cipher is input directly by the hand, inconvenience on the carrying side as seen in conventional devices is removed, copying is not also conducted and there is no possibility of damage and abrasion. Since the device is controlled extremely strictly, no cipher is leaked, and safety and privacy can be ensured.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of "keys" for locking, unlocking and starting / stopping operations that frequently come into contact with public and private parties in daily life.

[0002]

2. Description of the Related Art Conventionally, a key normally used must always be carried, and may be lost. In addition, the security is extremely low because the replication is very easy. Furthermore, since most keys are made of metal, if used for a certain period of time, both the key part and the lock part will be worn out, so that there is a disadvantage that the original function is deteriorated. Even when an IC card is used as a key, the above-mentioned problems of inconvenience and loss in carrying are the same, and the card itself may be damaged due to insufficient hardness. Alternatively, if the IC card is placed on a magnetic object side or a high-temperature place, the internal function may be damaged. In addition, a key that uses a password and an electronic encryption key to enter it is certainly not inconvenient to carry or may be lost, but there is also a possibility that the security code or electronic encryption will be leaked in some form. Yes, there is a problem with confidentiality.

[0003]

SUMMARY OF THE INVENTION The present invention provides a conventional key as described above, which is inconvenient in carrying and low in security.
An object of the present invention is to provide a device that can solve all the problems of abrasion after a certain period of time, breakage due to materials and storage locations, or low confidentiality.

[0004]

According to the present invention, when a specific character, code or graphic is set as a code in the device in advance, and the code is input with a finger of an input device, the code in the device is set in the device. Numerical values are used to compare and identify the data that has already been set and stored, and to perform locking and unlocking of doors and start / stop of systems, etc., and perform the function as a key. Entering a key eliminates the need to carry a "key" as an "object" as always,
There is no worry about losing. Also, since it is not a "key" as a "thing", there is no danger of being duplicated by others and security is high,
There is no breakage and no wear after a certain period of use. Further, the device is very effective in securing security and privacy since it is impossible for others to imitate or search for the cipher since the cipher is precisely recognized and strictly controlled. is there.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific character, code or graphic is set and stored in a RAM (constant speed call storage) in the apparatus in advance as a code. When the user inputs the already set / stored code with his / her finger, the code is digitized, unnecessary parts are deleted, and the coordinates are linearized or curved, and the setting is performed. The code is compared with and identified with a certain code, and if the code is matched, the execution program is operated, and a desired result, that is, locking / unlocking of doors and starting / stopping of systems are obtained.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a specific character (eg, a) or a code (eg,
*) Or a figure (example: ◎) is determined, and is set and stored in the RAM (constant-speed calling storage unit) of the device as a code. The set and stored encryption is input with the finger of the hand using the input device 1. The input code is temporarily stored in the input data storage device 2 (RAM) in the device. After that, the input code is digitized, the portion determined to be unnecessary is deleted, and it is linearized or curved on the coordinates. Furthermore,
The CPU (central processing unit) as the execution device 3
A desired operation (locking and unlocking of doors, starting / stopping of a system, etc.) is executed when the data is compared with data already set in the RAM and identified, and the results match. The executed program is stored in the storage device 4 again.

[0007]

As described above, the key as the opening / closing and starting / stopping device by handwriting input according to the present invention is equivalent to a conventional key only by the act of inputting a specific code with the finger of the hand using the input device. Function, and the inconvenience of carrying, low security, the problem of abrasion after a certain period of time, the breakage due to the material and location, or the confidentiality of the conventional key. It is very difficult to solve problems such as lowness,
It is valid.
