2. Description of the Related Art It is said that there are more than 50,000 types of data input that can be processed by the computer, and there are cases where the number of data of one type is as large as several million. Conventionally, when inputting this type of data, a method of arranging a large number of input terminals and personnel at the same place requires a great deal of cost, and therefore there is a method of performing input work by using a person at home. In this case, in order to perform data input work, at the ordering source, the original data divided into workable amounts for each input person is sent by Takkyubin (registered trademark) or the like, and each input person inputs in batch processing, When the data input is completed, it is sent back to the ordering party together with the original data, and the above-mentioned work is repeated in order to verify the input data.

[0003]

However, in the above-mentioned conventional input method using a person at home, when there is a large amount of data, there is a problem in that the work of dividing each work into a workable amount of each input person becomes complicated. In addition, when multiple batch processing is performed, if one person's work does not proceed as planned, there is a problem that input of all data does not finish until the batch of the person who did not progress finishes. ,further,
Since the number of processings per batch is determined by the ability of the input person, there is a problem that it is difficult to flexibly change the input person and the number of processings during the work.

An object of the present invention is to solve the above conventional problems and to provide a data input / verification system capable of efficiently performing data input and verification work by a home-side personal computer. To do.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the data input / output of the present invention.
1 is a system configuration diagram showing an embodiment of a verification system.

In FIG. 1, on the data center side 1,
An authentication server 2 and a data management server 3 are installed, and the authentication server 2 and the data management server 3 are connected to a personal computer 5 on the home side 4 via the Internet. In the data management server 3, the image data obtained by converting the original data to be input into an image with a scanner is registered, and the primary input data and the primary input data input from the personal computer 5 on the home side 4 are stored. The verified and verified data is recorded,
It is stored.

When the registration of the image data in the data management server 3 is completed, the person at home who has been recruited in advance and has the login authority is contacted by mail or the like. The in-home person who receives the notification logs in to the authentication server 2 through a predetermined procedure.
The data input software on the home side 4 is downloaded from the management server of the data management server 3.

FIG. 2 is a flow chart for explaining the processing flow of the data input / verification system of FIG. First,
In step S1, the personal computer 5 on the home side 4 is set to the authentication server 2
The authentication confirmation process is performed, and in step S2, it is determined whether or not the person at home is qualified, and if not qualified, error processing is performed. If qualified, the data management server 3 is connected in step S3. To check the remaining image data,
In step S4, it is determined whether or not there is data. If there is no data, the work is completed. If there is data in step S5, the image data is acquired from the data management server 3, and in step S6, the resident performs the input operation by looking at the image data, and in step S7, the primary input data is sent to the data management server 3. After the transfer, steps S3 to S7 are repeated.

At the stage when a predetermined number of primary input data have been accumulated, the data management server 3 side transfers the primary input data to the home side 4 to check whether the primary input data has been correctly input. Perform processing to verify This verification processing is the same as the processing of steps S1 to S7. Just 1
The difference from the next input processing is that the home-resident I of the primary input data I
By referring to D (identification number), verification of data input by a home-resident having the same ID is prohibited. At the time of verification, if the content of the data differs from that of the primary input, an electronic warning sound is emitted to prevent further verification input. For error handling in this case, if the primary input is incorrect, enter the correct data and press the Enter key. If the verification input is incorrect, press the Cancel key and then enter the correct data again. I have to. The error frequency at this time is
It is stored in a computer and used for feedback to home users and for their ability evaluation.

The verified data whose verification has been completed are sequentially accumulated in the data management server 3, and the image data is divided for each ID to calculate the number of works and the data input fee. When data is input in this way, even if many homes perform input and verification, there is always only one data to be input and verified on the home PC, that is, there is only one time lag. Without doing so, the data input work can be completed almost at the same time. This is an image as if you were taking piles of blocks like piles one by one, and the time until completion of the person who took the last one is the total data input time.

Next, details of each processing in FIG. 2 will be described. FIG. 3 is a system configuration diagram for explaining the authentication confirmation processing in steps S1 and S2 of FIG.

[0013] By the way, conventionally, taking the WWW service on the Internet as an example, some WWW servers include
There is a membership site that provides services only to those who are qualified in advance. Such a server requests the client that has requested the service to send the user name and password, and the server side receives the received user name and password and the user name registered in advance in the database in the server. And by checking with the password,
It is determined whether the service can be provided to the client.

However, when this authentication is used,
It is necessary to save and manage the user name and password of the member in the database on the server side. Therefore, if a user newly joins, withdraws, or changes, the database must be updated each time. In addition, there is a problem that a lot of labor is required for maintenance. In addition, the client must remember the password without fail, and if the password is stolen, a third party can access the password.

Therefore, in the present invention, the problem of this authentication is solved. In FIG. 3, a large number of home-side computers 5 are connected to the authentication server 2 via the Internet. The authentication server 2 includes an authentication code creating means and an authentication code collating means, and
A database 2a storing a home-resident table, an ID table, and an authentication code creation program is connected. The home-resident table is a table in which the ID of each home-resident is registered, and the ID table is a table on which an authentication code described later is created. Home side personal computer 5
Is equipped with an authentication code creating means, and is connected to an IC card 5a storing the same ID table as the authentication server side. The recording medium is not limited to the IC card, and a recording medium such as a magnetic card or an optical disk may be used.

FIG. 4 is a diagram for explaining an example of a method of creating the ID table. Taking an arbitrary image (for example, a facial photograph) with a digital camera, etc., each pixel of the image data obtained by optically performing image processing is set as 8-bit data
They are arranged in a matrix. Number of matrices, ie I
The capacity of the D table is preferably about 2 KB, for example 16
The number of columns is 8000 rows. According to this example, I
Since the D table is created, it is impossible to create the same thing and the security can be improved.

FIG. 5 is a diagram for explaining the authentication code creating program. An arbitrary number of elements (for example, 6 to 20) are selected from the ID table of FIG. 3, and the selected elements are arranged to create an authentication code. It should be noted that the arbitrary element and the arbitrary number are changed each time this program is used. Further, the order of arrangement may be reversed or randomly arranged.

An authentication method having the above configuration will be described. In FIG. 3, when a connection request is made from the home-side personal computer 5 to the authentication server 2, the authentication server 2 requests the home-side personal computer 5 for an ID, and based on this, the home-side personal computer 5 transmits the ID. I do.

In the authentication server 2, the ID table is read by referring to the home-resident table, and the authentication code creating means creates an authentication code based on the authentication code creating program. Only the authentication code creating program used at this time is read. Is transmitted to the home-side personal computer 5. In the home-side personal computer 5, the authentication code creating means creates an authentication code by the method described in FIG. 5 based on the transmitted authentication code creating program and the ID table recorded in the IC card. Is transmitted to the authentication server 2.

In the authentication server 2, the authentication code transmitted from the home-side personal computer 5 is compared with the authentication code created in advance, and if they match, the connection permission information is transmitted. If the authentication codes do not match, a new authentication code is created again using the authentication code creating program, and only the authentication code creating program used at this time is transmitted to the home-side personal computer 5.

After the connection is completed, the authentication server 2 deletes the authentication code this time. Therefore, the authentication code is created only when the authentication is required, and since the authentication code does not exist after the connection is released, there is no fear that the authentication code is illegally acquired due to unauthorized intrusion or the like. The next time you connect, a new authentication code will be set by the above process, so even if the authentication code is hacked by a packet monitor, etc., it will not be used for the next connection and the safety will be dramatically improved. become.

Although the ID table is created by image processing in the above embodiment, a table in which random data such as a random number table combining numbers and letters is arranged may be used.

Next, the data input operation in step S6 of FIG. 2 will be described. FIG. 6 is a diagram for explaining an input screen according to the present invention. In FIG. 6A, the acquired image data 6 is displayed in the upper half of the screen, and the input screen 7 is displayed in the lower half. In the data input software according to the present invention, the image data 6
So that you can't save the image, you can use the application software's "Save image", "Send image by email",
Functions such as "storing images" are stopped, and confidentiality is kept so that image data is not left on the home-use personal computer. Also, at the moment when one image data is displayed to a home person, the data is masked so that the data is not displayed on another home person's personal computer, and is displayed on the other home person's personal computer. I'm trying not to be.

When the cursor K is set on the input item (here, the bill number) on the input screen 7 on the image data 6, the intersection 9 of the red cross hairs moves corresponding to the input item, You can easily enter the data at a glance,
When the cursor is moved to the next input item, the intersection 9 of the crosshair is also moved correspondingly. Figure 6
(B) shows a state in which the lower part of the image data 6 appears, and the cursor K and the intersection 9 have moved to the “current bill amount”. Therefore, it is sufficient for the person at home to always input by looking at the intersection 9 of the crosshair, and the crosshair automatically moves on the image data as the input progresses, so that the efficiency of the input work can be achieved.

[0025]

As is apparent from the above description, according to the present invention, input work is performed at home using the Internet, and input work at home using a personal computer from anywhere in the world. Will be possible. Also, compared to the conventional method where a large number of input devices and personnel are placed in the same place, rent and PC installation fees can be eliminated, and personnel can be secured nationwide. You can

In addition, even when a large number of people at home perform input and verification, there is always only one data item to be input and verified on the personal computer of the at-home person, that is, only one time lag occurs, and data is almost simultaneously acquired. The input work of can be completed, and the data input and verification work can be efficiently performed.

Further, since the authentication code is created only when the authentication is necessary, and the authentication code does not exist after the disconnection,
The conventional password management is not required, and highly secure authentication can be performed.
