Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image processing apparatus having a digital copying function, and more particularly to an image processing apparatus capable of storing and retrieving image data and an image management method of the image processing apparatus.
[0002]
[Prior art]
With the development of digital technology, image data can be recorded not only on paper as a copy but also as a file on a magnetic disk, optical disk, magneto-optical disk, or the like.
[0003]
An electronic filing system that stores image data captured by a scanner or the like as a file on a built-in magnetic disk or the like and retrieves the stored file again using a printer is disclosed in, for example, Japanese Patent Application Laid-Open No. 62-219769. Is disclosed.
[0004]
The conventional electronic filing system as described above reads image data, stores it as an image file in a built-in magnetic disk device, and assigns a document ID to the image file so that the document ID can be discriminated electronically. And so on. Then, the bar code is synthesized at a predetermined position on the first page of the stored image data or a page having a characteristic image to create a registration sheet for the user to grasp the contents of the image data, and the registration Print the sheet.
[0005]
Next, when retrieving the stored image data, the barcode of the registration sheet is read by a barcode reader, the barcode of the registration sheet is converted into a document ID, and the image file is converted based on the document ID. By specifying, desired image data can be easily taken out.
[0006]
Conventionally, the filing function as described above has been incorporated in a dedicated filing apparatus. However, in recent years, digital image equipment such as a fax machine and a printer are integrated on the basis of a digital copying machine to realize space saving. Digital multifunction peripherals have appeared, and digital multifunction peripherals incorporating a filing function for storing image data have emerged.
[0007]
[Problems to be solved by the invention]
However, in the conventional system as described above, when the barcode part is dirty and cannot be read at a decodable level, it is impossible to take out the registered image data.
[0008]
In the case of a copier-based system as described above, a flatbed type scanner is standard. If the registration sheet has already been filed or fixed with staples, the registration sheet must be removed once so that it can be read by the flatbed scanner.
[0009]
As a solution to such a problem, the document ID itself is printed as a number string or a character string at the bottom of the barcode, and the corresponding image data is specified and extracted by directly inputting the document ID from a keyboard or the like. A method is conceivable.
[0010]
However, in the above method, as long as the document ID is known, the image data can be extracted even if the registration sheet is not held. Furthermore, the document ID, which is file management information inside the electronic filing system, is disclosed as a print output as it is. Usually, the document ID is logically assigned sequentially for reasons such as the ease of system construction. Therefore, if the registration sheet of the image data registered before and after the image data to be extracted is held, the document ID of the image data to be extracted is estimated from the document ID printed on the registration sheet. Is possible.
[0011]
As described above, the above method has a high risk of illegally extracting the image data, and has a serious problem in maintaining the confidentiality of the image data.
The present invention has been proposed in view of the above circumstances, and provides an image processing apparatus that can prevent unauthorized extraction of the image data and can increase the confidentiality of the image data. With the goal.
[0012]
[Means for Solving the Problems]
  The present invention employs the following means in order to achieve the above object. First, an image processing apparatus to which the present invention is applied accumulates input image data in a storage unit 105, and a document ID corresponding to the input image data is sequentially generated by the image management unit 103 to sequentially generate the document ID. The image data is managed based on the document ID, and the input image data is associated with a document ID that specifies the image data.TableThe image output means 109 outputs it together with the display code.
[0013]
Also, specific image data is designated by inputting an ID mark or display code corresponding to the document ID, and the image output means 109 outputs the image data.
[0014]
  In the image processing apparatus, the document ID generated by the image management unit 103 isThe image data specified by the document ID can be specifiedOne-to-one correspondence with the document ID, andThe display code for other input image data cannot be estimated.It is converted to a scrambled document ID that is not logically sequential, and a display codeDoBased on the scrambled document ID, the image data andAbove display codeAre combined and output by the image output means 109.
[0015]
  Specifically, the document ID generated by the image management unit 103 isThe image data specified by the document ID can be specifiedOne-to-one correspondence with the document ID, andThe display code for other input image data cannot be estimated.It is converted to a scrambled document ID that is not logically sequential, and a display codeDoA scramble processing means for outputting based on the scrambled document ID, the image data, and the display code.DoThis is realized by including a pattern synthesizing unit 108 for instructing synthesis and outputting to the image output unit 109.
[0017]
  Therefore, since the scrambled document ID can be used for the display code to be output, it is not possible to estimate the display code of other image data from the display code and extract image data illegally..
[0018]
  In addition, the above display codeDoThe code type selection means 113 for the user to select whether to output based on the document ID or the scrambled document ID can be adopted.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
FIG. 1 is a functional block diagram showing the configuration of an embodiment of an image processing apparatus according to the present invention. The filing (accumulation) of image data in this image processing apparatus is performed together with a copy of an original as an example in the following figure Based on the configuration, the operation will be described. FIG. 2 is a flowchart showing this operation procedure.
[0026]
First, when the user instructs filing of image data together with copying using the operation panel 101a of the operation means 101 having a plurality of keys such as an LCD panel with a touch panel and a numeric keypad, the instruction information is displayed on the panel of the operation means 101. When the start button of the operation panel 101a is pressed, the panel control unit 101b gives an instruction to read an original to the image data input unit 102 such as a digital scanner, and the image management unit. 103 is instructed to file image data.
[0027]
Upon receiving the instruction, the image data input means 102 reads a document, converts it to digital, and stores it as image data in the buffer 104 (FIG. 2, step S1). At the same time, the image management means 103 that has received an instruction to file the image data generates a document ID consisting of, for example, a 7-digit number corresponding to the image data to be filed (steps S2 → S3). The document ID is assigned sequentially every time the image data is registered. The document ID is for specifying the image data, and may be generated based on, for example, a registration time.
[0028]
Next, the document ID generated by the image management unit 103 is notified to the scramble processing unit 106. The scramble processing means 106 converts the inputted document ID into a scrambled document ID that has a one-to-one correspondence with the document ID and is not logically sequential (step S4).
[0029]
In this embodiment, “exclusive OR” is used as the conversion method to the scrambled document ID. This “exclusive OR” performs a bit operation on the bit string of the reference numeral and the conversion target numeral, but the reference numeral in the scramble process and the descrambling is the same.
[0030]
For example, when image data is registered three times in succession, “0000001”, “0000002”, and “00000003” are assigned as the document ID in the order of registration. In this case, as the scrambled document ID, “0000004”, “0000007”, and “0000006” are obtained by exclusive OR with 0xFFFFFA (hexadecimal notation) as a reference value for the document ID.
[0031]
The scramble processing means 106 notifies the ID mark encoding means 107 as an ID mark code and the pattern composition means 108 as a display code of the scrambled document ID thus converted.
[0032]
The ID mark encoding means 107 notified of the ID mark code encodes it into an ID mark such as a two-dimensional barcode image pattern. The encoded ID mark is stored in the bit map memory of the pattern synthesis means 108 (step S5).
[0033]
Next, the pattern synthesis means 108 uses the ID mark stored in the bitmap memory, the image data held in the buffer 104, and the display code notified from the scramble processing means 106 as an ID mark. It is synthesized as an attached image (step S6). The synthesized image with the ID mark is a format in which the image data, the ID mark and the display code as shown in FIG. 3 are synthesized at a predetermined position by an image output means 109 such as an electrophotographic printer. Thus, an image sheet with an ID mark is printed on the printing paper using toner, ink, or the like (step S7).
[0034]
Therefore, the image sheet with the ID mark in the example in which the image data is registered three times in succession is printed with the display code and the ID mark based on the scrambled document ID as shown in FIG. Is done.
[0035]
Next, the registration transfer unit 112 assigns a file name based on the document ID received from the image management unit 103 and accumulates the image data stored in the buffer 104 in the storage unit 105 such as a hard disk. (Step S8).
[0036]
  Next, if there are two or more pages of originals, the image data input means 102 reads the next original, digitally converts it, and stores it in the buffer 104 as image data (step S).9→ S1). The image data for the second and subsequent pages are printed as they are by the image output means 109 and then stored in the storage means 105 (steps S2 → S7 → S8). Thereafter, when this operation is repeated and there are no more documents, the filing process and the copy operation are finished.
[0037]
In the above-described embodiment, an example in which filing (accumulation) of the image data is performed together with a copy of the document is shown. However, the present invention is not limited to this. It can be performed together with facsimile transmission, printing operation of the image data from a personal computer or the like, or can be performed only by filing operation. The operation can be designated by the user by the operation means 101.
[0038]
Next, an operation for taking out the image data stored in the storage unit 105 as described above will be described below. FIG. 5 is a flowchart showing this operation.
As shown in FIG. 4, the image data is extracted by specifying the image data by reading the image sheet with the ID mark, and the display code printed as a number string below the ID mark. There is a method of direct input using a key.
[0039]
First, the user selects a document retrieval method using the operation panel 101a (FIG. 5, step S11).
In the case of the method of designating image data using the image sheet with ID mark, the user selects “image sheet with ID mark” in FIG. 4 and places the image sheet with ID mark on the image data input means 102. . The instruction information is held in the panel control unit 101b of the operation unit 101. The panel control unit 101b sends the image sheet with the ID mark to the image data input unit 102 when the start button of the operation panel 101a is pressed. Give instructions for reading.
[0040]
Upon receiving the instruction, the image data input means 102 reads the image sheet with the ID mark, digitizes it, and stores it in the buffer 104 as image data (steps S12 → S13). Next, the ID mark decoding unit 111 cuts out the image data at the position where the ID mark exists from the image data stored in the buffer 104 (step S14), decodes the ID mark, and performs the above-described processing of the image sheet with the ID mark. An ID mark code is obtained and notified to the scrambled document ID decoding means 110 (step S15).
[0041]
The scrambled document ID decoding unit 110 converts the notified ID mark code, that is, the scrambled document ID into the document ID corresponding to the scrambled document ID, and notifies the image management unit 103 (step S16). . Here, the input scrambled document ID is exclusive-ORed with 0xFFFFFA (hexadecimal display) as a reference value and converted to the document ID.
[0042]
Next, the image management means 103 instructs the registration transfer means 112 to read out image data corresponding to the document ID (step S17). In response to the instruction, the registration transfer means 112 reads the image data from the storage means 108 to the buffer 104, and the image data read in this way is output from the image output means 109 (step S18). .
[0043]
On the other hand, when the image data is designated by directly inputting the display code, the user selects “display code input” in FIG. 4 and inputs the display code. This instruction information is held in the panel control unit 101b of the operation means 101. The panel control unit 101b scrambles the display code, that is, the scrambled document ID, which is input when the start button of the operation panel 101a is pressed. The document ID decoding unit 110 is notified (step S19).
[0044]
The scrambled document ID decoding unit 110 converts the scrambled document ID notified to the document ID corresponding to the scrambled document ID in the same manner as when image data is designated by the image sheet with the ID mark, and manages the image management. The means 103 is notified (step S16). Subsequent processing is performed in the same manner as when image data is designated by the image sheet with the ID mark, and image data corresponding to the document ID is output from the image output means 109 (steps S17 → S18).
[0045]
In this embodiment, the scramble processing means 106 notifies the ID mark encoding means 107 of the scrambled document ID as the ID mark code and the pattern composition means 108 as the display code. Instead, the document ID that has not been scrambled by the scramble processing means 106 is notified to the ID mark encoding means 107 as the ID mark code, and the scrambled document ID is notified to the pattern composition means 108 as the display code. It can also be set as the structure to do.
[0046]
In the case of this configuration, the image sheet with ID mark in the example in which the image data is registered three times in succession, the display code based on the scrambled document ID, the document, as shown in FIG. The ID mark based on the ID is printed.
[0047]
As described above, since the scrambled document ID is used for the display code of the image sheet with the ID mark, even if image data is continuously registered, the registration order can be changed by simply reading the display code. It cannot be estimated. Therefore, it is impossible to extract image data illegally by estimating the display code of another image sheet with an ID mark from the display code.
[0048]
Further, by encoding the ID mark based on the scrambled document ID, even if the ID mark is decoded, a display code for other image data cannot be estimated, and image data is taken out illegally. I can't.
(Second Embodiment)
In the first embodiment, the configuration in which whether the document ID or the scrambled document ID is used as the display code and the ID mark code has been set in advance has been described. Then, the structure which made this selectable by the user is described.
[0049]
FIG. 7 is a functional block diagram showing the configuration of another embodiment of the image processing apparatus according to the present invention. The filing (accumulation) of image data in this image processing apparatus will be described with reference to the case where copying is performed together with the copy of an original. The operation is described together with the configuration based on the above. FIG. 8 is a flowchart showing this operation procedure. In addition, about the same structure as 1st Embodiment, description is abbreviate | omitted using the same code | symbol.
[0050]
First, when the user uses the operation panel 101a of the operation means 101 to instruct the filing of image data together with copying, the code type selection means 113 causes the operation panel 101a to display the image sheet with the ID mark as shown in FIG. A selection screen for selecting whether to use the document ID or the scrambled document ID as the display code and the ID mark code is displayed. Here, the user selects “ON” on the selection screen when using the scrambled document ID as the display code and the ID mark code, and selects “OFF” when using the document ID. . (FIG. 8, step S21).
[0051]
The instruction information is held in the panel control unit 101b of the operation unit 101. The panel control unit 101b instructs the image data input unit 102 to read a document when the start button of the operation panel 101a is pressed. In addition, the image management unit 103 is instructed to file image data. Further, the panel control unit 101b notifies the code type selection means 113 which of “ON” and “OFF” is selected as the display code and the ID mark code, respectively.
[0052]
Upon receiving the instruction, the image data input means 102 reads the original, converts it into digital, and stores it in the buffer 104 as image data (step S22). At the same time, the image management means 103 that has received the filing instruction for the image data generates a document ID consisting of, for example, a 7-digit number corresponding to the image data to be filed (step S23 → S24), and performs the scramble processing. The means 106 is notified. The document ID is assigned sequentially every time the image data is registered.
[0053]
The code type selection means 113 selects “OFF” to output the display code based on the scrambled document ID when “ON” is selected as the display code by the user. Then, the scramble processing means 106 is instructed to output the display code based on the document ID. Further, if “ON” is selected as the ID mark code by the user, the ID mark code is output based on the scrambled document ID. If “OFF” is selected, the ID mark code is output. The scramble processing means 106 is instructed to output the code for use based on the document ID.
[0054]
Next, the scramble processing means 106, based on the instructions of the code type selection means 113, if the scrambled document ID is necessary, the inputted document ID as in the first embodiment. The document ID is converted to the scrambled document ID that corresponds to the document ID on a one-to-one basis and is not logically sequential (steps S25 → S26).
[0055]
Further, the scramble processing means 106 uses the scrambled document ID or the document ID converted as described above based on an instruction from the code type selection means 113 as an ID mark code in the ID mark encoding means 107. The pattern synthesizing means 108 is notified as the display code.
[0056]
Here, the ID mark code and the display code, for example, expand the document ID of the 7-digit number or the scrambled document ID to an 8-digit number, and set the eighth digit as a “scramble flag column”. The “scramble flag column” indicates whether the document ID or the scrambled document ID, “1” is set for the scrambled document ID, and “0” is set for the document ID.
[0057]
For example, when the scrambled document ID is selected, the ID mark code and the display code corresponding to the document ID “0000001” are “1-0000004”. When the document ID is selected, the ID mark code and the display code corresponding to the document ID “0000002” are “0-0000002”.
[0058]
The ID mark encoding means 107 notified of the ID mark code encodes the ID mark. The encoded ID mark is stored in the bit map memory of the pattern synthesis means 108 (step S27). Next, the pattern synthesis means 108 uses the ID mark stored in the bitmap memory, the image data held in the buffer 104, and the display code notified from the scramble processing means 106 as an ID mark. It is synthesized as an attached image (step S28). The synthesized image with an ID mark is printed as an image sheet with an ID mark in a format in which the image data, the ID mark, and the display code are synthesized at a predetermined position by the image output means 109 (step). S29).
[0059]
Next, the registration transfer unit 112 assigns a file name based on the document ID received from the image management unit 103, and accumulates the image data stored in the buffer 104 in the storage unit 105 (step). S30).
[0060]
Thereafter, the processing when there are two or more pages of the document is the same as in the first embodiment (steps S31 → S22 → S23 → S29 → S30).
Here, the image data is registered three times as in the example of the first embodiment, and the scrambled document ID is used as the display code and the ID mark code when the first image data is registered. Assume that the document ID is selected as the display code and the ID mark code when the second and third image data are registered. In this case, on the first image sheet with an ID mark, as shown in FIG. 10, a display code based on the scrambled document ID and the ID mark are printed. The display code based on the document ID and the ID mark are printed on the second and third image sheets with the ID mark.
[0061]
As described above, the display codes of the first and second image sheets with ID marks are not logically continuous. Further, the second and third display codes after descrambling are logically continuous.
[0062]
Next, an operation for taking out the image data stored in the storage unit 105 as described above will be described below. FIG. 11 is a flowchart showing this operation.
As in the first embodiment, the image data extraction method includes a method of designating image data by reading the image sheet with the ID mark, and the display printed as a number string below the ID mark. There is a method of specifying the code by directly inputting it using a key.
[0063]
First, in the method of designating image data using the image sheet with the ID mark, the ID mark decoding unit 111 cuts out the image data at the position where the ID mark exists from the image data stored in the buffer 104, and the ID mark Is the same as that in the first embodiment (FIG. 11, steps S41 → S45) until the ID mark code of the image sheet with the ID mark is obtained. .
[0064]
The ID mark code obtained by the ID mark decoding unit 111 is notified to the ID code determination unit 114.
The ID code discrimination means 114 discriminates whether the notified ID mark code is the document ID or the scrambled document ID based on the “scramble flag column” included in the ID mark code. (Step S46). That is, if the “scramble flag column” is “1”, it is the scrambled document ID, and if it is “0”, it is the document ID. If it is determined that the scrambled document ID, the scrambled document ID is notified to the scrambled document ID decoding unit 110. On the other hand, if it is determined that the document ID is the document ID, the document management unit 103 is notified of the document ID.
[0065]
The scrambled document ID decoding unit 110 converts the notified ID mark code, that is, the scrambled document ID into the document ID corresponding to the scrambled document ID, and notifies the image management unit 103 (step S47). . Here, the input scrambled document ID is exclusive-ORed with 0xFFFFFA (hexadecimal display) as a reference value and converted to the document ID.
[0066]
Therefore, when the ID mark code is either the document ID or the scrambled document ID, the document management unit 103 is notified of the document ID.
[0067]
Next, the image management means 103 instructs the registration transfer means 112 to read out the image data corresponding to the document ID (step S48). In response to the instruction, the registration transfer means 112 reads the image data from the storage means 108 to the buffer 104, and the image data read in this way is output from the image output means 109 (step S49). .
[0068]
On the other hand, when the image data is designated by directly inputting the display code, the user selects “display code input” in FIG. 4 and inputs the display code. The instruction information is held in the panel control unit 101b of the operation unit 101. The panel control unit 101b converts the display code input when the start button of the operation panel 101a is pressed into the ID code determination unit 114. (Step S50).
[0069]
Subsequent processing is performed in the same manner as when image data is specified by the image sheet with the ID mark, and image data corresponding to the document ID is output from the image output means 109 (steps S46 to S49).
[0070]
In the present embodiment, the code type selection unit 113 can select both the display code and the ID mark code. However, only one of the codes can be selected. For example, when the document ID is used as the ID mark code and the display code can be selected by the code type selection unit 113, the scramble processing unit 106 assigns the document ID to the ID mark. The ID mark encoding means 107 is notified as a code for use, and the scrambled document ID or the document ID is notified as the display code to the pattern composition means 108 based on an instruction from the code type selection means 113. .
[0071]
In this configuration, the image data is registered three times in a manner similar to the above example, and the scrambled document ID is selected as the display code when the first image data is registered, and the second and third It is assumed that the document ID is selected as the display code when registering image data. In this case, as shown in FIG. 12, the ID mark based on the document ID is printed on each image sheet with an ID mark. A display code based on the scrambled document ID is printed on the first image sheet with an ID mark, and a display code based on the document ID is printed on the second and third image sheets with an ID mark. Printed.
[0072]
As described above, since the user can select whether to use the scrambled document ID or the document ID for the display code of the image sheet with the ID mark, the user can select as needed. It is possible to select whether to register image data in a mode with high confidentiality or in mode with low confidentiality. Further, when the ID mark is configured to be able to select whether to encode based on the scrambled document ID or the document ID, the image data is registered in four modes having different confidentiality as required. It is possible.
[0073]
Even when the display code is directly input and image data is designated and taken out, the operation method is the same regardless of whether the display code is the document ID or the scrambled document ID. There is a unified operation method.
[0074]
In each of the above embodiments, a number is used as the document ID, but a character string may be included as long as it is logically sequential.
In each of the above embodiments, the ID mark uses a two-dimensional barcode, but the ID mark is not limited to this, and may be a general one-dimensional barcode, for example.
[0075]
In each of the above embodiments, “exclusive OR” is used for encoding and decoding of the scrambled document ID. For example, “bit shift”, “bit rearrangement”, and “combination thereof” are used. May be used.
[0076]
【The invention's effect】
  As described above, the image processing apparatus according to the present invention is not a document ID that is file management information in the system, but a scrambled document ID that has a one-to-one correspondence with the document ID and is not logically sequential.The pictureImage data registered before and after because it is used for the display code of the image sheetPaintingIt is difficult to extract other image data by inferring from the display code of the image sheet. For this reason, illegal image data can be prevented from being taken out, and confidentiality can be improved.
