Abstract

A key device for playing a role of a key for locking/unlocking doors indispensable for daily life and for starting/stopping various systems. Conventional keys made of metals or magnetic substances must be always carried and the possibility of loss exists. Breakage of the keys and wear with time also occur, and convenience is not high. Since duplication is easy, safety is low. Keys of a code number input system involves the possibility of leak of the code number and security is not high. In this invention, specific characters, symbols or figures are set in advance as a cipher in the key device. When this cipher is inputted by fingers through an input device, the cipher is converted to a numeric value and is compared with, and discriminated from, data that has been set already so as to lock/unlock the doors, to start/stop the systems and to play the function of the key. Since the cipher is directly inputted by hand, the necessity for carrying is eliminated, duplication is not possible, and breakage and wear do not occur. Further, because the device is controlled extremely strictly, leak of the cipher does not occur, and safety as well as privacy can be secured.

Description

Description Keys as lock / unlock and start / stop devices by handwriting input

The present invention belongs to the technical field of "keys" for locking, unlocking and starting / stopping operations that frequently come into contact in public and private life in daily life. Background art

Conventionally, keys that are normally used must always be carried, and may be lost or lost. In addition, the security is extremely low because the replication is very easy. Furthermore, since most keys are made of metal, there is a drawback that both the key and the lock are worn out after a certain period of use, and the original function is reduced. Even when an IC card is used as a key, the above-mentioned inconvenience and inconvenience of carrying the same card are the same, and the card itself has insufficient hardness, which may cause damage. Alternatively, if the IC force is placed on a magnetic object or in a high-temperature place, the internal function may be damaged. In addition, a key that is used by entering a personal identification number or electronic encryption does not cause any inconvenience or loss of carrying, but there is a possibility that the personal identification number or electronic encryption may be leaked in some way. It can be said that there is a problem in terms of confidentiality. Disclosure of the invention

According to the present invention, a specific character, code, or figure is set as an encryption in the device in advance, and when the encryption is input by a finger with an input device, the code is digitized in the device, and is already set and stored. Compare and identify the data to lock and unlock doors and The key function is performed by starting / stopping, etc., and the key is directly entered by hand, so the user does not need to carry the key as an object at all times. Also, do not worry about losing. In addition, since it is not a “key” as a “thing,” it is highly secure without fear of being copied by others, does not break, and does not wear out even after being used for a certain period of time. In addition, the device recognizes the symbol 精密 precisely and controls it strictly, so it is impossible for others to imitate or search for the code. It is. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a block diagram showing a configuration example of the present invention, FIG. 2 is a flowchart showing an operation flow of the device, and FIG. 3 is a block diagram showing a procedure of a function of the present invention. FIG. BEST MODE FOR CARRYING OUT THE INVENTION

In order to explain the present invention in more detail, this will be described with reference to FIG. 1 of the accompanying drawings.

First, a specific character (example: a) Power code (example: *) A power figure (example: ◎) is determined, and it is set and stored as a code in the RAM (constant speed call storage) of the device. Settings · Enter the saved cipher manually using the input device 1. The input encryption is temporarily stored in the input data temporary storage device 2 (RAM) in the device. After that, the input cipher is digitized, the part judged to be unnecessary is deleted, and it is linearized or curved on the coordinates. Further, the CPU (central processing unit) as the execution device 3 is compared with the data in the already set RAM and identified. Operation (locking / unlocking of doors and start / stop of systems) is executed. The executed program is It is stored again in storage device 4 內. Industrial applicability

As described above, the key as the locking / unlocking and starting / stopping device by handwriting input of the present invention can perform the same function as the conventional key only by the act of inputting a specific symbol with a finger using the input device. Doors and various systems that use keys in public places such as hotels, companies and government offices, as well as automobiles and personal computers It is suitable for wide-ranging use for everything related to daily start and stop actions such as.

Claims

The scope of the claims

1 When inputting coordinate input information such as a specific character, code, figure, figure

5 Eliminate unnecessary parts, further convert to straight lines and curves, compare and identify data that has already been set and stored, and play the key role of locking and unlocking doors and starting and stopping systems. Device.

2. In the device described in claim 1, the input means can be any pointing device such as an electronic ben, a mouse, a trackball, etc. besides the finger. Input devices include all electronic devices with pad surfaces, such as digitizers, tablets, and touch panels.

3. In the device described in claim 1, the cipher recognition is performed based on a ratio of how close the inputted cipher is to the cipher in the data, and the higher ratio is automatically selected. Encryption by function or stroke order

It also has the function of judging and identifying 15 It is also possible to add a switch to determine the number after inputting the code.

4. The storage device (4) ROM (read-only storage device) in Fig. 1 includes PROM (writable read-only storage device), EPRO M (erasable and rewritable read-only storage device), and mask ROM ( Rewriting

The ROM can be replaced by any device having a storage function such as a floppy disk / hard disk. Furthermore, the RAM (constant-speed call storage) as the input data storage device (2) in FIG. 1 includes a dynamic RAM (DRAM) and a static RAM (SRAM). Also, the R

25 AM is equipped with a storage function such as a floppy disk or hard disk. In addition, the CP (Central Processing Unit), which is the comparison, identification, and execution unit (3) shown in Fig. 1, can be used even if it has both RAM and ROM. It can be substituted.
