Description

  The present invention relates to an information conversion method, a program, an information conversion apparatus, and an information conversion system.

  In each field of the manufacturing industry such as food, chemistry, pharmaceuticals, and automobiles, information used for transmitting information on each manufacturing work process includes information necessary for production of the product. In general, it is desirable to conceal this information from other parties in order to differentiate it from other companies. In order to prevent such outflow of production information, access to business establishments other than those involved is restricted, or an authentication machine or the like is provided in the system to restrict functions that can be used according to user attributes. Yes.

  In developing a manufacturing system (hereinafter, referred to as a system as appropriate), part or all of the development work is outsourced to others in order to reduce development costs. In this case, in order for the developer to understand the business process, the client may have to disclose information necessary for production to the developer. In this case, a confidential information holding contract is often concluded between the requester and the developer. However, confidential information with high importance may not be disclosed to others even if it is a developer. To conceal such information, replace the information you want to conceal with a meaningless character string. A method has been proposed.

For example, Patent Document 1 discloses a method for replacing a character string with a control code.
Non-Patent Document 1 discloses a method in which code portions are common and only a character string is managed by an external file.

Japanese Patent Laid-Open No. 02-2734

MSDN Library, Resource File (Visual Studio), Microsoft Corporation, [Search February 25, 2010], Internet <URL: http: //msdn.microsoft.com/en-us/library/7zxb70x7 (VS.80 ) .aspx>

  The technique described in Patent Document 1 has a problem that the user cannot know the attributes (process, equipment, etc.) of the control code unless the control code is analyzed.

  In the technique described in Non-Patent Document 1, a system user or a system developer has to prepare a character string after replacement. Furthermore, in the case where the replaced character string is a character string, a numerical value, or both of which does not make sense for an external person, the developer himself cannot understand the attribute as in the case of Patent Document 1. Thus, there was a problem that the system development was difficult. In addition, when the replaced character string is expressed as, for example, “manufacturing process 1” or “quality item 2”, not only to system users and system developers, but also to outside parties not related to the system. However, there is a problem that it indicates what the attribute of the character string indicates and may lead to leakage of information.

  In the technique described in Patent Document 1 and the technique described in Non-Patent Document 1, information to be concealed, for example, a character string indicating a process name, and numerical values such as a lot size and a lead time are stored in one storage unit. The Similarly, dummy character strings and numerical values that are replaced in place of the information to be concealed are also stored in the storage unit of the same or different information processing apparatus. That is, information before conversion and information after conversion are managed in a centralized manner. In this case, there is also a problem that it is vulnerable to the risk of data loss due to intrusion from outside or malfunction.

  In the technique described in Patent Document 1 and the technique described in Non-Patent Document 1, a dummy character string or numerical value generation rule design or a character string or numerical value that is replaced in place of the information to be concealed is used. There was a problem that it was necessary to prepare each time and it was inefficient.

  The present invention has been made in view of such a background, and an object of the present invention is to easily realize information concealment.

In order to solve the above-described problem, the present invention provides an information conversion method in an information conversion apparatus that converts information, and the information conversion apparatus stores a character string described in the information in the storage unit and the character The character string-attribute correspondence information in which the attribute indicated by the column is associated is stored, and the attribute conversion information in which the attribute is associated with the code string is stored. The attribute corresponding to the character string to be converted that is designated in advance is acquired from the character string-attribute correspondence information, the code string corresponding to the acquired attribute is acquired from the attribute conversion information, The acquired code string is added before the character string to be converted, and the character string portion of the character string to be converted to which the code string is added is converted into a random code string. .
Other solutions will be described as appropriate in the embodiments.

  According to the present invention, information hiding can be easily realized.

In the present embodiment, when the browsing requester 4 makes a screen browsing request (screen browsing request) for production management information (information on the manufacturing process) via the client terminal 3, the screen browsing request is sent via the server 2 to the information It is sent to the conversion device 1. If the person who wishes to browse 4 is a person who cannot view the production management information screen without converting the information, the information conversion apparatus 1 performs an information conversion process and sends the information-converted screen to the server 2. The browsing requester 4 browses a screen sent to the server 2 via the client terminal 3.
As described above, in the present embodiment, the browsing candidate 4 browses the screen via the client terminal 3, but the screen browsing request may be transmitted or the screen may be browsed via the server 2. Good.
In this embodiment, one client terminal 3 and one server 2 are used, but a plurality of clients may be used.

  The information conversion device 1 includes a control unit 110 that controls the operation of the information conversion device 1 itself, a storage unit 120 such as a HDD (Hard Disk Drive) or a ROM (Read Only Memory), a calculation unit 130 having a calculation function, and a keyboard. And an input unit 140 such as a mouse or a network interface card (NIC), and a display unit 150 such as a display.

The control unit 110 determines whether or not the person 4 who wishes to browse can view the production management information. If the person who cannot view the production management information cannot be browsed unless the information is converted, the control unit 110 converts the information and converts the production management information. An information conversion unit 111 that generates a screen to be displayed and transmits the screen to the server 2 is provided.
The storage unit 120 includes a table database 121 having various tables necessary for information conversion processing, and a production management information database 122 having production management information.
The table database 121 includes a character string-attribute correspondence table 123 which will be described later with reference to FIG. 4, an attribute conversion table 124 which will be described later with reference to FIG. 5, a unit conversion table 125 which will be described later with reference to FIG. 7 stores a character string color table 126 and the like which will be described later.
The production management information database 122 stores production management information and is a viewer who is information for determining whether or not the browsing applicant 4 can browse the production management information, such as the name and affiliation of the browsing applicant 4.

(Screen example before conversion)
FIG. 2 is an example of a pre-conversion screen according to this embodiment. In the present embodiment, as an example of production management information, an example of a manufacturing process in a factory or the like is shown. However, the present invention is not limited to this, and a food manufacturing process including “sterilization / sterilization”, “packaging”, etc. It may be production management information.
The pre-conversion screen 200 is a screen that can be viewed by an ordering employee or a person who has confidentiality obligations.

The pre-conversion screen 200 includes a process chart 201, an attribute information display area 202, and a menu button 203.
The process table 201 is a table displaying plan data, actual data, and information on the next process in the manufacturing process.
In the attribute information display area 202, the name of the creator who created the process table, the affiliation, the date and time when the process table was displayed, the process name displayed as “bending lot” in FIG. Information is displayed.
The menu button 203 is a button for returning to the top page or menu page of the application.

  The pre-conversion screen 200 is an example of the pre-conversion screen 200 used in the information conversion system 10, and a plurality of process tables 201 and attribute information display areas 202 may be provided or omitted. In addition to the process table 201 and the menu button 203, there may be a table or button, a text box for receiving a character string or numerical value input by the user, and the like.

The process chart 201 on the pre-conversion screen 200 includes a cart number column, a status column, an assembly lot column, a mass column, and a confirmation button column.
The carriage number is a number having an integer value assigned to each carriage. In order to identify the carriage by this number, the carriage and the integer value have a one-to-one relationship. Here, integers such as “1” and “2” are used. However, the numbers may not necessarily be integers such as “1” and “2” as long as the code can identify the cart such as a manufacturing number of the cart. .

The state column stores information indicating the state of the carriage. In the example of FIG. 2, the state of the carriage such as “moving” or “vacant” is displayed.
The assembly lot column stores a lot number of an assembly process that is a part of the manufacturing process.
The mass column stores information related to the mass of the object mounted on the carriage.
The confirmation button row is provided with a confirmation button. The confirmation button is used, for example, in the following. The user mounts an object on the carriage and measures the mass, and the information conversion apparatus 1 captures the measured value and displays it on the mass column of the pre-conversion screen 200. The user visually confirms the displayed measured value, and if it is a normal value, the measured value is stored in the production management information database 122 by pressing the confirm button.

(Screen example after conversion)
FIG. 3 is a diagram illustrating an example of a post-conversion screen according to the first embodiment.
The post-conversion screen 300 has a process table 301, an attribute information display area 302, and a menu button 303, as in the pre-conversion screen 200 of FIG. Since these are the same as the respective units 201 to 203 in FIG. 2, detailed description is omitted, but information that the system developer wants to conceal is concealed as a code.

  For example, in order to conceal the characters “trolley” in the cart number of FIG. 2, the character string “cart number” is converted to “fard% number” in the post-conversion screen 300. The prefix “fa” is a prefix representing equipment that is an attribute of the carriage, is selected with reference to the character string-attribute correspondence table 123 and the attribute conversion table 124 described later, and is added to the head of the code string. The The portion of “rd%” corresponds to “cart”, which is obtained by replacing “cart” with a randomly generated code.

The state of the carriage in the state column is excluded from conversion because it is difficult to express the characteristics of the production management information. Therefore, the contents stored in the status column are not converted.
Since the information on the assembly lot sequence in FIG. 2 may express the characteristics of the production management information, the character string is converted by the same method as the “cart number”. The information stored in the lot string is also converted into a character string. Note that the content of this column is such that a portion corresponding to “AA” such as “AA-12” in FIG. 2 is converted into a random code sequence, and a portion corresponding to “−12” is not converted. The portion corresponding to “−12” may also be converted into a random code string. Further, the character string may be converted by the same method as in the second embodiment described later.

Since the mass string in FIG. 2 may also express the characteristics of the production management information, the character string is converted by the same method as the “cart number”. Note that the information corresponding to the contents of the mass sequence in FIG. 2 has the same number of digits but is converted with a randomly generated numerical value, but is not limited thereto, and is converted with a numerical value based on a predetermined rule. Alternatively, conversion may be performed using a random code string that is not a numerical value.
The confirmation button row is excluded from conversion because it is difficult to express the characteristics of the production management information.
In addition, in the process chart 301 of the post-conversion screen 300 in FIG. 3, the character string of the record based on the actual data is blue, the character string of the record based on the plan data is red, and so on according to the type of data. You may change the color of the columns.
In this way, the viewer can know the type of data being browsed.

  In addition, the creator name, affiliation, and display date / time in the attribute information display area 202 in FIG. 2 are excluded from conversion because it is difficult to express the characteristics of the production management information. Since the information such as the required time may express the characteristics of the production management information, in the post-conversion screen 300, “prd)% red lot” and “prew & fDedsfsdsz #” are respectively used in the same manner as “cart number”. It has been converted to a code string.

(Various conversion tables)
Next, a conversion table used for converting the screen information from FIG. 2 to FIG. 3 will be described with reference to FIGS.

(String-attribute correspondence table)
FIG. 4 is a diagram illustrating an example of a character string-attribute correspondence table according to the first embodiment.
The numbers in the character string / attribute correspondence table 123 are numbers given to combinations of character strings and attributes.
The character string is a character string used in production management information such as “cart” and “assembly”. The attribute indicates an attribute of a character string such as equipment or process.

(Attribute conversion table)
FIG. 5 is a diagram illustrating an example of an attribute conversion table according to the first embodiment.
The numbers in the attribute conversion table 124 are numbers given to combinations of attributes and prefixes.
The attribute is an attribute on production management information such as equipment and process, and is the same as the attribute of the character string-attribute correspondence table 123 of FIG.
The prefix code string is a code string into which a corresponding attribute is converted. This code string may be a single code that is not a code string, such as alphabets, numbers, “@”, and “$”.

(Unit conversion table)
FIG. 6 is a diagram illustrating an example of a unit conversion table according to the first embodiment.
The numbers in the unit conversion table 125 are numbers given to combinations of units and suffixes.
The unit is a unit of data used in production management information such as “kg”, “pieces”, “times”, and the like.
A suffix is a code to which the corresponding unit is converted. This code may be a code string.

(Character color table)
FIG. 7 is a diagram illustrating an example of a character string color table according to the first embodiment.
In the character string color table 126, the number is a number given to a combination of the data type and the character string color.
The data type indicates the type of data displayed on the pre-conversion screen 200 (FIG. 2) and the post-conversion screen 300 (FIG. 3), such as performance data and plan data.
The color of the character string corresponds to the data type, and in the example of FIG. 7, the code string “blue” is displayed on the converted screen if it is actual data, and “red” is displayed on the converted data. The

<Flowchart>
Next, the information conversion method according to the first embodiment will be described with reference to FIGS. 8 and 9 with reference to FIGS.
FIG. 8 is a flowchart showing a procedure of overall processing of the information conversion method according to the first embodiment.
First, the browsing requester 4 operates the server 2 via the client terminal 3 to transmit a screen browsing request from the server 2 to the information conversion device 1, and the information conversion device 1 transmits the transmitted screen browsing request. Is received (S101).

  The information conversion unit 111 of the information conversion apparatus 1 that has received the screen display request stores the browsing requester information (S102). The browsing requester information includes the name and affiliation of the browsing requester 4 and is included in the screen browsing request. Alternatively, the screen browsing request includes a number for identifying the browsing candidate 4, for example, an employee number, and the information conversion apparatus 1 makes an inquiry to an employee management database (not shown) based on these information, You may acquire the name, affiliation, etc. of browsing candidate 4.

  Next, the information conversion unit 111 refers to the viewer information 127 of the storage unit 120 based on the browsing requester information, and whether or not the browsing requester 4 can browse the pre-conversion screen 200 (FIG. 2). Is determined (S103). Specifically, the information conversion unit 111 determines whether or not the browsing information 127 includes information such as the name and affiliation of the browsing requester 4 included in the browsing requester information. 4 determines whether the pre-conversion screen can be viewed

  As a result of step S103, if the viewing applicant 4 can view the pre-conversion screen 200 (FIG. 2) (S103 → Yes), the information conversion unit 111 requests a screen browsing for the pre-conversion screen 200 that has not converted information. The pre-conversion screen 200 is displayed when the client terminal 3 that has transmitted the request to the original server 2 acquires the pre-conversion screen 200 from the server 2 (S104).

  As a result of step S103, if the browsing candidate 4 cannot browse the information (S103 → No), the information conversion unit 111 performs the conversion process described later in FIG. 9 (S105), and displays the post-conversion screen 300 (FIG. 3). When it is created, the created post-conversion screen 300 is transmitted to the server 2 that is the screen browsing request source, and the client terminal 3 that is the screen browsing request source acquires the post-conversion screen 300 from the server, thereby displaying the post-conversion screen 300. (S106).

FIG. 9 is a flowchart showing the procedure of the conversion process in step S105 of FIG.
First, the information conversion unit 111 searches the production management information that is the target of the screen browsing request, and searches for the attribute from the character string-attribute correspondence table 123 (FIG. 4) using the character string to be converted as a key. Obtain (S201). Note that the character string to be converted is designated in advance when the production management information is created.
Then, the information conversion unit 111 refers to the attribute conversion table 124 (FIG. 5), acquires the prefix code string corresponding to the attribute acquired in step S201, and performs the acquired character string as a target character string. (S202). This process can be omitted. That is, the attribute may be added to the beginning of the character string without being converted to the prefix code string.
Next, the information conversion unit 111 refers to the unit conversion table 125 (FIG. 6) and converts the corresponding unit character string into a corresponding suffix code string (S203).
Then, the information conversion unit 111 converts the character string to be converted into a random code string (S204).
Next, the information converter 111 refers to the character string color table 126 (FIG. 7) based on the data attribute information and performs character string color conversion for converting the character string of the corresponding data into a corresponding color. (S205). The process of step S205 may be omitted.

According to the first embodiment, the display content can be changed depending on the affiliation of the person who wants to browse 4 and the information can be displayed without being converted for those who can browse the information. For those who can, by converting the information, by displaying attribute codes that cannot be understood by outsiders, it is possible to prevent information leakage.
Furthermore, since the attribute of the converted information can be determined by adding a prefix code string corresponding to the attribute of the data, for example, an outside system developer or the like acquires the attribute conversion table 124 in advance. Thus, when viewing the post-conversion screen 300, the detailed contents cannot be known, but the contents of the data can be inferred. In other words, those who can browse information such as insiders, who cannot browse specific information, but who can browse the characteristics of information such as attributes, those that can not be browsed, attributes that can not be guessed, such as screen browsing The reference level can be set.

<< Second Embodiment >>
Next, a second embodiment of the present invention will be described with reference to FIGS.
In the second embodiment, instead of the code string as in the first embodiment, other character strings (for example, higher conceptual words) are replaced.
In the information conversion system 10 according to the second embodiment, the tables 123 to 126 stored in the table database 121 of FIG. 1 are replaced with a character string conversion table 128 described later in FIG. It will be omitted.

Since these are the same as in FIG. 2, detailed description is omitted, but information that the system developer wants to conceal is concealed as another character string.

The process table 1001 is a table having an equipment 1 number column, a status column, a process 2 lot column, a quality item 3 column, and a confirmation button column. “Equipment 1” indicates “cart” in FIG. 2 and is converted into a character string “equipment 1” which is a word for concealing “cart”.
The status column indicates the status of the carriage. This “state” information is not subject to character string conversion because it is difficult to express the characteristics of production management information.
“Process 2” in the process 2 lot string indicates “assembly” in FIG. 2 and is converted into a character string “process 2” because there is a possibility of expressing the characteristics of the production management information.
The quality item 3 in the quality item 3 column is obtained by converting the mass in FIG.
The confirmation button in the confirmation button row does not convert the character string as in the state row.

  Further, the “bending lot” and “required assembly time” (FIG. 2 respectively) in the attribute information display area 1002 are converted into “process 1 lot” and “process 2 quality item 4”, respectively.

(Character string conversion table)
FIG. 11 is a diagram illustrating an example of a character string conversion table according to the second embodiment.
The character string conversion table 128 stores a character string before conversion and a character string after conversion in association with each other.
The correspondence relationship is, for example, “trolley” → “facility 1”, “bending” → “process 1”, “assembly” → “process 2”, “mass (kg)” → “quality item 3”, and the like.
In the second embodiment, the information conversion apparatus 1 generates a post-conversion table based on the character string conversion table 128 shown in FIG.
