Description

The present invention relates to a technique for suppressing information leakage, which is a concern when digitizing a handwritten document.

Examples of handwritten information include various application procedure documents. For example, personal information such as name, date of birth, address, and occupation is described in the credit card application form.
While such personal information should be strictly managed, digitization is essential. This is because data management and various related processes are difficult without digitization.

Regarding digitization processing, it is empirically known that 100% certainty cannot be expected even if OCR software is used. For this reason, almost all digitization processing relies on manual input.
Because it depends on manpower, the following problems occur.

As a first problem, there is a possibility of information leakage from the time when a handwritten document to be digitized is born until the start of input work.
That is, the first document manager in the place where the handwritten document to be digitized is born has to give the handwritten document to the second document manager who performs the digitization process. This will be described in more detail.

  The first document administrator rarely executes digitization processing, and the second document administrator who is a different person from the first administrator performs digitization processing, that is, handwritten characters on the information terminal. Type to create a digital document. Since it is not possible to hand over the original handwritten document from the first administrator to the second administrator due to the risk of loss, a duplicate (duplicate) is handed over. If a duplicate is present, there is a possibility that the duplicate will be lost, illegally copied (including when taken with a camera, scanned with a scanner) and taken away.

As a second problem, there is a possibility that an input error occurs between the start and completion of an input operation for digitization.
In order to suppress the occurrence of input mistakes, the following methods are generalized. In other words, the same handwritten document is input by a plurality of input workers, and a third party (supervisor) corrects and unifies the mismatched portion.

  If the method for solving the second problem is adopted, there is a possibility that information leakage occurs even during the period from the start to completion of the input operation for digitization. That is, a copy (duplicate) is also given to the supervisor. Since there is a supervisor copy, there is a possibility that the copy will be lost or illegally copied and taken away.

  There is a technique disclosed in Patent Document 1 regarding management of handwritten documents and security measures. That is, it is a technique aimed at maintaining high security and improving input efficiency when data entry of form image data including personal information is performed.

Further, Patent Document 2 discloses a technique for further enhancing a technique of using invisible toner at a location where personal information for providing security is secured, and ensuring security even when invisible toner is insufficient. Yes.

JP 2006-72783 A JP 2007-78981 A

In the techniques of Patent Documents 1 and 2 described above, it is impossible to eliminate the fundamental leakage route in which a person engaged in digitization copies personal information.
When there is a supervisor who checks for input errors, the leakage route of when personal information is delivered to the supervisor or when processing after delivery is not properly performed cannot be cut off.

The problem to be solved by the present invention is to reduce the risk of leakage of personal information due to the intervention of a person involved in data entry.

In order to solve the above-described problems, the present invention provides the following inventions.

(Glossary)
The “handwritten document” refers to a document in which characters and numbers are handwritten in blanks in a predetermined format prepared in advance. Each sheet in which the same characters are copied to a plurality of sheets when characters are entered on one sheet is also included in the “handwritten document” and “original sheet”.
“Division” is divided to a level that does not have any meaning even if personal information described in the handwritten portion of the divided sheet data leaks due to the division.
The AD conversion terminal (D) is an information communication terminal for converting analog data into digital. Specifically, it is a personal computer, a tablet terminal, a smartphone, a mobile phone, or the like.

  The operator of the AD conversion terminal (D1, D2, D3,...) Receives and outputs only the divided sheet data (for example, d2-1) that is a part of the divided original sheet (d1). The entire sheet (d1) is not seen. Therefore, the risk of leakage of personal information due to the operator can be significantly reduced.

(Variation 1 of the first invention)
The handwritten document security device according to the first invention is more preferably formed as follows.
That is, the divided sheet data transmission means (E) transmits one divided sheet data (d2-3) to a plurality of AD conversion terminals (D3, D4),

(Function)
The divided sheet data transmission means (E) transmits one divided sheet data (d2-3) to a plurality of AD conversion terminals (D3, D4). The received AD conversion terminals (D3, D4) respectively convert the divided sheet data (d2-3) into digital data, and create divided sheet digitized data (d4-3, d4-3 ′). Then send it back.

When the match determination means (K) determines that they do not match, the supervisor transmission means (L) transmits to the supervisor terminal (M) related to the supervisor for inputting regular data. In the supervisor terminal (M), it is confirmed which of the divided sheet digitized data (d4-3, d4-3 ′) is the correct conversion, and regular data (d4-3) is input as necessary. Then, the regular data (d4-3) is sent back.

An operator of the AD conversion terminal (D3, D4) may not perform correct digital conversion input. Therefore, each piece of data is transmitted to a plurality of AD conversion terminals (D3, D4) to obtain two divided sheet digitized data (d4-3, d4-3 ′). When the divided sheet digitized data (d4-3, d4-3 ′) match, it is considered that almost correct digital conversion input has been made.
If the divided sheet digitized data (d4-3, d4-3 ′) do not match, any of the AD conversion terminals (D3, D4) may have been erroneously input. Only in the case of disagreement, the decision is entrusted to the third party supervisor terminal (M) operator.
From the above flow, the possibility of erroneous input is reduced and the burden on the operator of the AD conversion terminals (D3, D4) and the operator of the supervisor terminal (M) is reduced.

The divided sheet data transmission means (E) also transmits the temporary digitized data (d1-2).

(Function)
The scanning data (d1-1) scanned by the scanning means (A) is digitized by the provisional digitizing means (P) and the handwritten portion (d0) by OCR processing to create provisional digitized data (d1-2). . The provisional digitized data (d1-2) is transmitted to the AD conversion terminal (D) by the divided sheet data transmission means (E).

  Digitization of handwritten characters using OCR technology cannot be perfected. However, it is possible to save labor for input, which may contribute to an improvement in processing speed. Therefore, the burden on the operator of the AD conversion terminal (D) is reduced by subjecting the scanning data (d1-1) to OCR processing of the handwritten portion (d0) by the temporary digitizing means (P).

Hereinafter, the present invention will be described more specifically with reference to embodiments and drawings. The drawings used here are FIGS. 1 to 7.
Note that component requirement symbols and data type symbols that do not appear in the figure in the description are displayed in parentheses.

(Figure 1)
FIG. 1 shows a given format (member application form XX) and a sheet (original sheet d1) on which information required by the format is handwritten. Further, a state in which the original sheet d1 is divided two-dimensionally to generate divided sheet data d2-1, d2-2, d2-3,.

The original sheet d1 includes personal information such as the applicant's full name, postal code, and address.
Hereinafter, FIGS. 2 to 6 show changes in hardware configuration and data conversion that reduce the risk of leakage of personal information when the handwritten portion d0 described in the original sheet d1 is digitized. .

  The two-dimensional division means (B) described later records the format (member application form XX) where handwritten information is not added, and where it is reasonable to divide the format on the XY coordinate axes. The target is stored in advance.

  In FIG. 1, among the handwritten portions d0 in the original sheet, among the portions where the name is handwritten with katakana and kanji, “Mr” and “Name” are divided. As will be described later, the AD conversion terminals for AD conversion of the handwritten portions d0 of “Mr.” and “Name” are transmitted differently. That is, the terminal operators are different. It will be clear that this alone reduces the risk of leakage of personal information.

  The postal code is divided into the first three digits and the last four digits in the same way as dividing "Mr." and "Name". The prefecture, municipality, town name, street address, building name, etc. are also divided. As described above, the AD conversion terminals for AD conversion are transmitted differently.

(Figure 2)
FIG. 2 shows a hardware configuration of a handwritten document security server and a plurality (two in this figure) of AD conversion terminals D1 and D2.
The handwritten document security server functions as a handwritten document security device for improving security when digitizing the handwritten portion (d0) in the original sheet d1 on which the handwritten document is written.

  That is, the scanning means A for scanning the original sheet d1 on which the handwritten document is written, and the scanned data scanned by the scanning means A are divided into a plurality of digital sheets in two dimensions, thereby dividing the divided sheet data (d2-1 , d2-2, d-2-3,..., and the divided sheet data (d2-1, d2-2, d-2) divided by the two-dimensional division means B -3,...) Can be restored and associated with the linking data (d3-1, d3-2, d3-3,. Divided sheet data transmission means E for transmitting sheet data (d2-1, d2-2, d-2-3,...) To separate AD conversion terminals D1 and D2, and digital by the AD conversion terminal D Digital data receiving means F for receiving the divided sheet digitized data (d4) converted into data, and the received divided sheet Data synthesizing means G for synthesizing the digitized data (d4) with the digitized completed sheet (d5) from the handwritten document part (d0) of the original sheet (d1) based on the association data (d3) And comprising.

The AD conversion terminal D1 includes divided sheet data receiving means for receiving, from the handwritten document security server, divided sheet data (d2-1) that is a part of the original sheet (d1) on which the handwritten document is written and divided. Da, a screen output means D-b for outputting the received divided sheet data (d2-1) on the screen, and a handwritten portion (in the divided sheet data (d2-1) displayed on the screen output means Db) ( d0) is digitally input, and the divided sheet digitized data (d4-1) input by the input means Dc is linked to the divided sheet data (d2-1). Digital data transmitting means D-d for transmitting to the handwritten document security server.
Since the AD conversion terminal D2 also has the same hardware configuration as the AD conversion terminal D1, the illustration is simplified.

(Figure 3)
With the hardware configuration described with reference to FIG. 2, the original sheet d-1 is processed as follows.
First, the original sheet d-1 is converted into image data by the scanning means (A). The image data is divided by the two-dimensional dividing means (B), and divided sheet data d2-1. d2-2, d2-3,... are created.

  Divided sheet data d2-1. For d2-2, d2-3,..., in order to enable reproduction to the original original sheet when digitization is completed, the association data d3-1, d3-2, d3-3 are used. ,... Are assigned in a one-to-one correspondence and stored in a predetermined storage device.

The divided sheet data d2-1 is transmitted by the divided sheet data transmission means (E) to the AD conversion terminal D1. Further, the divided sheet data transmission means (E) transmits the divided sheet data d2-2 to the AD conversion terminal D2.
Terminal operators of the AD conversion terminal D1 and the AD conversion terminal D2 are different (a different algorithm is used to ensure that they are different). Therefore, each terminal operator can browse only the divided sheet data d2-1 or d2-2 which is a part of the original sheet d1. The two-dimensional dividing means (B) divides the divided sheet data d2-1 or d2-2, which is a part of the original sheet d1, so that it does not make sense by itself.

The terminal operator of the AD conversion terminal D1 operates the input means (Dc) while looking at the handwritten part (d0) displayed on the screen output means (Db), and appropriately (appropriately) corresponding to the handwritten part (d0). Digital data, which is considered by the terminal operator), that is, the divided sheet digitized data d4-1.
When the input is completed, the digital data transmission means (Dd) is used to transmit to the digital data reception means (F) of the handwritten document security server.

  The AD conversion terminal D2 creates the divided sheet digitized data d4-2 in the same manner as the AD conversion terminal D1, and transmits it to the digital data receiving means (F) of the handwritten document security server.

  As described above, the divided sheet digitized data d4-1, d4-2, d4-3,... Collected in the digital data receiving means (F) of the handwritten document security server are linked data d3-1, d3. Using -2, d3-3,..., The digital synthesizing means (G) creates a digitization completion sheet d5. Here, digitization of the handwritten portion (d0) of the original sheet d1 is completed.

(Fig. 4)
FIG. 4 shows a second embodiment in which whether or not there is an input error in the handwritten document security server is checked with respect to an input by a terminal operator of the AD conversion terminal, and correct / incorrect is determined.
Here, a case where one divided sheet data d2-3 is sent to two AD conversion terminals D3 and D4 will be described.

  The AD conversion terminal D3 converts the divided sheet data d2-3 into the divided sheet digitized data d4-3, and the AD conversion terminal D4 converts the divided sheet data d2-3 into the divided sheet digitized data d4-3. Suppose you convert it to '.

  The divided sheet digitized data d4-3 and d4-3 'are received by the digital data receiving means F in the handwritten document security server. Then, the correctness determination means H determines which of the divided sheet digitized data d4-3 and d4-3 'is correct. Then, the correct / incorrect transmission means J transmits the determination result to the AD conversion terminals D3 and D4.

Although detailed illustration is omitted, there are various algorithms for how the correctness determining means H determines correctness.
For example, in the example shown in FIG. 4, it is assumed that two AD conversion terminals D3 and D4 are returned. However, one divided sheet data d2-3 is transmitted to more AD conversion terminals and returned, and the majority decision is made. This is an algorithm in which the most common is “positive” and the one that is not “positive” is “no”.

(Fig. 5)
A system for determining correctness without providing correctness determination means H in the handwritten document security server is shown in FIG. 5 as a third embodiment.
In place of the correctness determination means H shown in FIG. 4, a match determination means K is provided for determining whether or not there are a plurality of types of divided sheet digitized data for one divided sheet data d2-3.

  For the divided sheet data determined by the coincidence determining means K as inconsistent (in this figure, d4-3 and d4-3 ′ are inconsistent), the supervisor transmitting means L sends the divided sheet data d4-3 to the supervisor terminal M. d4-3 ′ is transmitted.

  A supervisor who operates a supervisor terminal is a person who has experience in digital conversion of character input. The role of selecting which of the divided sheet data d4-3 and d4-3 ′ that have been transmitted (inconsistent) is correct, and if neither is correct, is to newly input regular data. Bear.

  For the supervisor who plays the above role, the supervisor terminal M includes a digitized data receiving unit Ma that receives the divided sheet data, a screen output unit Mb that outputs the received divided sheet data on the screen, Normal data input means Mc for inputting data or selecting data determined to be normal from a plurality of displayed divided sheet data, and normal data input or selected (here d4-3) And normal data transmission means M-d for transmitting to the handwritten document security server.

  The regular data receiving means N receives the regular data d4-3 transmitted to the handwritten document security server. Then, as described with reference to FIG. 2 and the like, the data synthesizing means G synthesizes the data using the association data.

(Fig. 6)
FIG. 6 is a conceptual diagram for specifically explaining the relationship between the coincidence determining means (K) shown in FIG. 5 and the supervisor terminal M.
It is assumed that the digitized sheet digitized data d4-3 is “Platinum Furukawato 411” by the AD conversion terminal D3 on which the operator V performs an input operation. Further, it is assumed that the divided sheet digitized data d4-3 ′ is “Platinum old hand” by the AD conversion terminal D4 on which the operator W performs an input operation.

  The divided sheet digitized data d4-3 and d4-3 'are transmitted from the AD conversion terminals D3, D4 to the handwritten document security server, and the digital data receiving means (F) receives them. Then, the coincidence determination means K determines whether or not they match. Since it is a mismatch due to digital data, it can be handled very easily.

When mismatch data is found by the match determination means K, the divided sheet digitized data d4-3 and d4-3 ′ that are mismatched are transmitted to the supervisor terminal M. The supervisor terminal M outputs the divided sheet digitized data d4-3, d4-3 ′ and the corresponding handwritten portion (d0).
The supervisor who operates the supervisor terminal M determines which divided sheet digitized data is correct by comparing the handwritten portion output on the screen and the divided sheet digitized data d4-3 and d4-3 ′. .

If neither of them is correct, the supervisor operates the supervisor terminal M to input regular data (d4-3) to obtain digitized sheet data.
Then, determination or correct input is transmitted to the handwritten document security server, and data synthesis as digital data is performed.

  Note that the determination result of “correct” or “false” is not directly transmitted from the supervisor terminal M to the AD conversion terminals D3 and D4. In the handwritten document security server, the accuracy rates of the AD conversion terminals D3 and D4 are counted and used as a scoring for each operator of the AD conversion terminal.

(Fig. 7)
FIG. 7 shows an input operation performed by an operator of the AD conversion terminal (D) by performing digitization to some extent by performing OCR processing in the handwritten document security server in order to reduce the trouble of handwriting input. Is an option to reduce
This is effective when the number of handwritten characters to be digitized is large.
This will be specifically described below.

The provisional digitizing means P performs OCR processing on the original sheet d1 scanned by the scanning means A. The data subjected to the OCR process is divided by the two-dimensional dividing unit B.
However, the scanned image data that is not subjected to OCR processing is also divided by the two-dimensional dividing means B.

Divided sheet data (d2-1, d2-2, d2-3,...) That are to be divided are two types: data that has not been subjected to OCR processing, and analog digitized data that has undergone OCR processing. Is transmitted to the AD conversion terminal (D).
This is because when the OCR process is considered inappropriate for the operator of the AD conversion terminal (D), it is possible to refer to the original when it is unclear what the original handwriting is.
