Abstract

PURPOSE:To improve the safety by inputting coordinates or a handwritten character inputted with a pen and registering its stroke information as a dictionary for password and using this dictionary to recognize an inputted handwritten password. CONSTITUTION:When a handwritten password is inputted to a coordinate input device 21 with an input pen, its coordinate data is stored in a password character coordinate storage area 29 of a random access memory 27, and this data is subjected to vector processing by a handwritten character recognition device 32 and is registered in a password dictionary storage area of a read-only memory 23. At the time of password collation, vectors of inputted handwritten characters are collated with vectors registered in the dictionary for password, and password coincidence is displayed on a display device 31 if a pertinent password is found as the result of collation, but noncoincidence is displayed if it is not found. Thus, easy access is prevented even if the password is known.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a computer or file management system having an online handwritten character recognition function by having a recognition dictionary exclusively for passwords.
The present invention relates to a pen input password system having a high degree of security including personal handwriting information.

[0002]

2. Description of the Related Art Conventionally, in this type of password system, only the matching between the character code of the password registered in advance and the input character code is performed.

[0003]

However, with the above method, even with regard to personal files and highly confidential systems, there is a risk that anyone who has a password can access it.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a highly secure pen input password system which cannot be easily accessed even if the password is known.

[0005]

In order to achieve the above object, the present invention registers means for inputting coordinates of handwritten characters input by a pen and stroke information of the input handwritten characters as a password dictionary. By providing a means and a means for recognizing the input handwritten password using the password dictionary instead of the normal character recognition dictionary, the password including the handwriting information can be matched. is there.

[0006]

According to the present invention, because of the above-described configuration, the password dictionary registered in advance stores the direction vector of the password character including the habit of the handwriting of the registrant. Even if you enter the password, you will not be given access rights because the handwriting is different,
You can build a password system with a high degree of security.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic exploded perspective view showing a device configuration of a pen input computer having a pen input password system according to an embodiment of the present invention. In FIG. 1, 11 is an input pen used for input. Reference numeral 12 is a coordinate reading device. Reference numeral 13 is a display unit using a liquid crystal or the like, in which an input frame and input coordinates are echoed back and displayed. 14 is a main body.

FIG. 2 is a schematic assembly perspective view of the above-mentioned pen input computer. In FIG. 2, reference numeral 15 is a coordinate input area, and the user inputs data in this frame. 1
Reference numeral 6 is a display area in which a normal computer screen is displayed.

FIG. 3 is a circuit block diagram of a pen input computer according to an embodiment of the present invention. In FIG.
Reference numeral 21 is a coordinate input device for inputting coordinate data.
Reference numeral 22 denotes a central processing unit, which controls each unit according to a program stored in the read-only memory 23. Reference numeral 23 is a read-only memory, and the program is stored in the program storage area 24, the password dictionary is stored in the password dictionary storage area 25, and the character recognition dictionary storage area 2 is stored.
6, a recognition dictionary is stored. A random access memory 27 has a work area 28, and stores the coordinate data input to the password character coordinate storage area 29 and the input character coordinate storage area 30. A display device 31 is a program storage area 2 of the read-only memory 23.
Data is obtained from the program stored in 4, and a frame or the like for input is displayed. 32 is a dictionary storage area for password 25 and a dictionary storage area for character recognition 2 of the read-only memory 23 for handwritten characters pen-input to the coordinate input device 21.
6 is a handwritten character recognition device for identifying using a dictionary in FIG.

Next, the password judgment operation in the above embodiment will be described with reference to the flowchart of FIG. First, in the case of a normal password expressed by a character code, characters are handwritten and input to the coordinate input device 21 using an input pen (step 41). Next, the input coordinate data is stored in the input character coordinate storage area 30 of the random access memory 27 (step 42). Next, the stored coordinate data is vector-processed by the handwritten character recognition device 32 (step 43), collated with the dictionary stored in the character recognition dictionary storage area 26 of the read-only memory 23, and a matching process is performed (step 43). 44). Next, as a result of the collation, if there is a corresponding character code, the password match is displayed on the display device 31, and if not, the password mismatch is displayed (step 45).

In the more strict password judgment operation, first, at the time of registration, a handwritten password is similarly input from the coordinate input device 21 (step 41). next,
The coordinate data is stored in the password character coordinate storage area 29 of the random access memory 27 (step 4).
2). Next, the stored coordinate data is vector-processed by the handwritten character recognition device 32 and decomposed into a vector of 8 directions or 16 directions (step 43) and registered in the password dictionary storage area 25 of the read-only memory 23 (step). 46). At the time of password verification, the input handwritten character vector and the vector registered in the password dictionary are verified (step 44), and as a result of the verification,
If there is a corresponding password, the password match is displayed on the display device 31, and if not, the password mismatch is displayed (step 45).

As described above, according to the present embodiment, when a password or a user code is determined, the conventional method for determining the character code state after character recognition and the stroke of an input handwritten character are used. By preparing two methods, that is, the method according to the present invention for judging information as a password dictionary, a more secure password system can be constructed.

[0013]

As is apparent from the above embodiment, the present invention has means for inputting coordinates of handwritten characters input by a pen and means for registering stroke information of the input handwritten characters as a password dictionary. Since the input handwritten password is provided with a means for recognizing characters using a password dictionary, it is possible to construct a highly secure pen input password system including personal handwriting information.
