  Embodiments of an image processing apparatus and an image complete erasing program according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram showing an overall configuration of an embodiment of an image processing apparatus to which the present invention is applied.

  An image processing apparatus 100 illustrated in FIG. 1 includes an image reading unit 10, an image processing unit 20, and an image forming unit 30, and the image processing unit 20 includes an input processing unit 21, an input data storage unit 22, a drawing processing unit 23, A drawing processing data storage unit 24, an image data output unit 25, and an output data storage unit 26 are provided.

  The image processing apparatus 100 performs a copying operation by processing the image data read by the image reading unit 10 by the image processing unit 20 and outputting the processed image data to the image forming unit 30.

  Further, a host computer 200 is connected to the image processing apparatus 100, and an image forming operation is performed in which image data transferred from the host computer 200 is processed by the image processing unit 20 and output to the image forming unit 30. .

  The input processing unit 21 of the image processing unit 20 inputs image data read by the image reading unit 10 or image data (image image data) transferred from the host computer 200. The input data storage unit 22 stores the image image data input by the input processing unit 21.

  The drawing processing unit 23 converts the image image data stored in the input data storage unit 22 and processes it to create image image data that can be drawn. The drawing processing data storage unit 24 stores the image image data created by the drawing processing unit 23.

  The image data output unit 25 outputs the image image data created by the drawing processing unit 23 to the image generation unit 30. The output data storage unit 26 stores the image image data output from the image data output unit 25.

  During the copying operation by the image processing apparatus 100, the image image data of the document read by the image reading unit 10 is passed to the image forming unit 30 via the input processing unit 21, the drawing processing unit 23, and the image data output unit 25. Printed on a print medium. At this time, the input processing device 21, the drawing processing unit 23, and the image data output unit 25 use the input data storage unit 22, the drawing processing data storage unit 24, and the output data storage unit 26, as necessary. Data is stored, and image image data that is no longer needed by the input processing device 21, the drawing processing unit 23, and the image data output unit 25 is deleted.

  Similarly, during the image forming operation by the image processing apparatus 100, the image image data transferred from the host computer 200 is transferred to the image forming unit 30 via the input processing unit 21, the drawing processing unit 23, and the image data output unit 25. Is printed on the print medium. At this time, the input processing device 21, the drawing processing unit 23, and the image data output unit 25 use the input data storage unit 22, the drawing processing data storage unit 24, and the output data storage unit 26, as necessary. Data is stored, and image image data that is no longer needed by the input processing device 21, the drawing processing unit 23, and the image data output unit 25 is deleted.

  In this embodiment, even if the erasure process is forcibly interrupted by turning off the power during the erasure process of the data entity of the file, the file that was being erased is specified at the subsequent restart and the erasure process is executed. You can continue.

  In the file erasing process according to the present invention, when an instruction is given to erase a file containing image data stored in the input processing device 21, the drawing processing unit 23, and the image data output unit 25, FIG. As shown in FIG. 6, the top directory of each of the file systems 100-1 to 100-3 that manages the files to be deleted stored in the input data storage unit 22, the drawing processing data storage unit 24, and the output data storage unit 26, respectively. A file move process is executed to rewrite the file names of the erase target files 111 to 121 into the prepared erase target storage directories 110 to 130.

  In this file move process, the path name (file name), which is access information for access, is moved into the deletion target storage directory, but the data entity is not moved, and only the file management information is rewritten. For this reason, the file movement process is completed instantly.

  In FIG. 2, the file system 100-1 shows a case where the type of the file to be deleted is a directory, and the file systems 100-2 and 100-3 show a case where the type of the file to be deleted is a normal file. ing. In FIG. 2, the deletion target file before movement is indicated by a dotted line, and the deletion target file after movement is indicated by a bold line.

  Next, the data entity of the file to be erased is erased. As shown in FIG. 3, this file erasing process is performed by overwriting from the head position of the data entity to the end of the data entity with the erasing data. Here, the erasure data uses a combination of random numbers, zeros, constants, etc., and the overwriting process is repeated from one to a plurality of times with any combination of erasure data depending on the confidentiality of the data.

  In FIG. 3, an area 300 indicated by a halftone line indicates an area overwritten with erasure data, and FIG. 3A shows a file A in which file use areas in which data entities are stored are continuous. In this case, FIG. 3B shows a case where the file use area 300 is a file B that exists in an intervening manner with an unused area 310 in which no data entity is stored.

  When the file erasure process is completed by overwriting the erasure data on the data entity, the file subjected to the erasure process is deleted by a normal file deletion process.

  According to such a configuration, the first file moving process is completed instantly. In addition, even if the data entity deletion process is forcibly interrupted during the process of deleting a file data entity due to power-off etc., it remains in the deletion target storage directory prepared in the top directory of each file system. Is a file whose processing has been interrupted during the data entity erasure process, and the file that was in the data entity erasure process can be easily identified.

  Therefore, when the process is restarted by restarting or the like, the deletion target storage directory prepared in the top directory of each of the file systems 100-1 to 100-3 is searched, and the data entity deletion process of the remaining files is sequentially executed. The file data entity can be erased without omission of the file to be erased.

  Further, in the present invention, the original file name does not exist due to the file movement process, so that it appears that the deletion is completed instantly from other processes that access the file. For this reason, even if it takes a long time to erase the data entity, there is no need to be aware of that from other programs.

  In addition, by performing the above processing in the order of file movement processing, file deletion processing, and file deletion processing, it can be configured to notify the user that the deletion of the data entity has been completed. The file deletion process and the file deletion process and the file deletion process are separately performed, so that the file deletion process can be performed asynchronously with the file movement process.

  The first embodiment is applied to the image processing apparatus 100 shown in FIG. 1. When the image data recorded in the input data storage unit 22, the drawing processing data storage unit 24, and the output data storage unit 26 is deleted, Instead of the file deletion process, the file complete deletion process is performed to overwrite the data for deletion on the data entity.

  In the first embodiment, the file complete deletion process is performed in the order of the file movement process, the file deletion process, and the file deletion process, thereby performing the file deletion process and the file deletion process in synchronization with the file movement process. Do.

  Here, as shown in FIG. 2, the file movement process is performed by file systems 100-1 to 100-100 that manage the storage files of the input data storage unit 22, the drawing process data storage unit 24, and the output data storage unit 26, respectively. -3, the erasure target files 111 to 121 are rewritten and moved to the erasure target storage directories 110 to 130 prepared in the respective top directories.

  In addition, as shown in FIG. 3, the file erasure process is performed by overwriting from the start position of the data entity to the end of the data entity with erasure data such as random number data, constant data, and zero data. The file erasing process by overwriting the erasing data is performed a plurality of times by combining any erasing data according to the confidentiality of the erasing target data.

  The file deletion process is performed by a normal file deletion process provided by the system.

  Next, details of the file complete erasure process according to the first embodiment will be described with reference to the flowcharts shown in FIGS.

  In FIG. 4, when the file complete erasure process is started, it is first checked whether the file type to be erased is a directory (step 401). If the file type to be deleted is a directory (YES in step 401), the process proceeds to step 403.

  If it is determined in step 401 that the file type to be erased is not a directory (NO in step 401), then it is checked whether the file type to be erased is a normal file (step 402). If it is determined that the file type to be erased is a normal file (YES in step 402), the process proceeds to step 403. If it is determined that the file type is not a normal file (NO in step 402), detailed description will be given later. The process proceeds to the file deletion process in step 600.

  In step 403, a unique file name is acquired in the erasure target storage directory in the same file system in order to perform the process of moving the erasure target file (normal file or directory). Then, the file name of the erasure target file (normal file or directory) is rewritten with the acquired file name, and this file is moved into the erasure target storage directory of the file system (step 402).

  When moving this file, the data entity of the file to be deleted whose file name has been rewritten does not move, but the path name (file name) for accessing this data entity is stored in the storage directory for deletion. Moving.

  When the movement of the file in step 402 is completed, a file erasing process is next performed (step 500).

  FIG. 5 is a flowchart showing details of the file erasing process in step 500. In this file erasure process, the erasure target storage directories 110, 120, and 120-3 respectively provided in the file systems 100-1, 100-2, and 100-3 shown in FIG. Based on the file name of the file that has been renamed and moved to 130, the data entity of the file to be erased is overwritten with the data for erasure and is completely deleted.

  In FIG. 5, when the file erasure process is started, it is first checked whether the file type to be erased is a directory (step 501). If it is determined that the file type is not a directory, that is, a normal file (NO in step 501), it is checked whether the file size is 0 (step 502). If it is 0 (YES in step 502). ), The process proceeds to the file deletion process in step 600, but if it is determined that it is not 0 (NO in step 502), the data substance of the file with the file name is overwritten with the data for deletion based on the file name of this file. An erasure process is performed.

  In this erasure process, first, which erasure data is set in advance, that is, which data among random data, constant data, zero data, etc. is used as erasure data to be overwritten on the data entity, and which erasure data The erasure mode in which order is overwritten and the number of repetitions of the overwriting process in this erasure mode are acquired (step 503).

  Next, data for erasure is acquired corresponding to the acquired erasure mode and the number of repetitions (step 506), and an overwriting process is performed on the data entity of the erasure target file with the acquired erasure data (step 506). .

  The acquisition of data for erasure in step 504 and the overwriting process in step 506 are repeated until it is determined in step 504 that the erasure process is completed. If it is determined in step 504 that the erasure process is completed (YES in step 504). The process proceeds to the file deletion process in step 600.

  If it is determined in step 501 that the file type to be deleted is a directory (YES in step 501), the file name of the file in this directory is first acquired (step 508), and the acquired file name is acquired. Based on the above, the erasure processing of files in this directory is recursively executed (from step 501) (step 509). The normal file erasing process in the directory is performed by sequentially repeating the erasing mode and the number of repetitions, the acquisition of erasing data, and the overwriting process in the same manner as the processing from step 503 to step 506.

  The acquisition of the file name in step 508 and the recursive execution of the deletion process in step 509 are repeated until it is determined in step 507 that the file in the directory is empty. In step 507, the file in the directory is determined to be empty. Then (YES in step 507), the process proceeds to the file deletion process in step 600.

  FIG. 6 shows the file deletion process in step 600. The file deletion process executed in step 600 is a normal file deletion process provided by the system.

  That is, in FIG. 6, when this file deletion process is started, a file deletion process is performed in which a file whose data entity is overwritten by data for deletion is deleted by a normal file deletion process provided by the system. (Step 601) By this file deletion process, the complete deletion process of the first embodiment is completed.

  FIG. 7 is a flowchart illustrating an erasing process when the image processing apparatus 100 according to the first embodiment is restarted.

  In the first embodiment, the file to be erased has been renamed and moved to the erase target storage directory 110, 120, 130 of the file system 100-1, 100-2, 100-3 by the file move process. When the erasure target file complete erasure process is completed, the erasure target file moved to the erasure target storage directory 110, 120, 130 is only deleted, and therefore when the image processing apparatus 100 is restarted, the erasure target storage directory 110, 120, 130 is deleted. If the file to be erased remains, this file is a file whose erasure process has been interrupted due to a power failure or the like during the erasure process of the data entity of the file.

  In the first embodiment, when the image processing apparatus 100 is restarted, the deletion target storage directories 110, 120, and 130 of the file systems 100-1, 100-2, and 100-3 are searched, and there are remaining files. Based on the file name of the file, complete erasure of the data entity of the file is executed again.

  In FIG. 7, when the erasing process at the time of restart is started, a file system is acquired (step 701), an erasure target storage directory is acquired from the acquired file system (step 703), and the acquired erasure target storage is acquired. It is checked whether the file in the directory is empty (step 704).

  If the file in the erasure target storage directory is not empty (NO in step 704), the file name in the erasure target storage directory is acquired, and the erasure process of the file is recursively performed based on the acquired file name. Execute.

  This file erasure process is performed in step 704 until the file in the erasure target storage directory becomes empty.

  If it is determined in step 704 that the file in the erasure target storage directory is empty (YES in step 704), the process returns to step 701, the next file system is acquired, and the processing in steps 703 to 705 is repeated. .

  If it is determined in step 702 that all file systems have been acquired by the above processing (YES in step 702), the erasing process at the time of restarting is terminated.

  FIG. 8 is a flowchart showing details of the file erasing process in step 705 of FIG.

  This file deletion process is the same as the file deletion process shown in FIG. 5, and is executed as follows.

  That is, in FIG. 8, when the file erasure process is started, first, it is checked whether the file type to be erased is a directory (step 801). Here, it is determined that the file type is not a directory, that is, a normal file. Then (NO in step 801), it is checked whether the file size of this file is 0. If it is 0 (YES in step 802), the process proceeds to step 810, but if it is determined that it is not 0 (NO in step 802). Then, the preset erase mode and the number of repetitions of the overwriting process in this erase mode are acquired (step 803).

  Next, data for erasure is acquired in accordance with the acquired erasure mode and the number of repetitions (step 806), and an overwriting process is performed on the data entity of the file to be erased with the acquired erasure data (step 806). .

  This erasure data acquisition and overwriting process is repeated until it is determined in step 804 that the erasure process is completed. If it is determined that the erasure process is completed (YES in step 804), the process proceeds to step 810.

  If it is determined in step 801 that the file type to be deleted is a directory (YES in step 801), the file name of the file in this directory is first acquired (step 808), and the acquired file name is acquired. The process of erasing files in this directory is recursively executed based on the above (step 809), and this process is repeated until it is determined in step 807 that the files in the directory are empty. Is determined to be empty (YES in step 807), the process proceeds to step 810.

  In step 810, a file deletion process is performed to delete a file that has been deleted by overwriting the data for deletion described above by a normal deletion process provided by the system, and this file deletion process causes the file deletion process to be performed. finish.

  In the first embodiment, since the file erasure process is performed in synchronization with the file movement process, it can be configured to notify the user that the complete erasure of the data body of the file has been completed.

  Similarly to the first embodiment, the second embodiment is applied to the image processing apparatus 100 illustrated in FIG. 1, and image image data recorded in the input data storage unit 22, the drawing processing data storage unit 24, and the output data storage unit 26. At the time of deletion, a file complete erasure process for overwriting data for erasure on a data entity is performed instead of a normal file deletion process.

  However, in the second embodiment, the first embodiment performs the file deletion process and the file deletion process in synchronization with the file movement process, whereas the file deletion process and the file deletion process are performed as the file movement process. And asynchronously.

  In FIG. 9, when the file move process of the second embodiment is started, it is first checked whether the file type to be deleted is a directory (step 901). If the file type to be deleted is a directory (YES in step 901), the process proceeds to step 903.

  If it is determined in step 901 that the file type to be erased is not a directory (NO in step 901), then it is checked whether the file type to be erased is a normal file (step 902). If it is determined that the file type to be erased is a normal file (YES in step 902), the process proceeds to step 903.

  In step 903, a unique file name is acquired in the erasure target storage directory in the same file system in order to perform the process of moving the erasure target file (normal file or directory). Then, the file name of the deletion target file (normal file or directory) is rewritten with the acquired file name, and the file is moved into the deletion target storage directory of the file system (step 904).

  When moving this file, the data entity of the file to be deleted whose file name has been rewritten does not move, but the path name (file name) for accessing this data entity is stored in the storage directory for deletion. Moving.

  When the movement of the file in step 904 is completed, the movement process of this file ends.

  If it is determined in step 902 that the file type is not a normal file (NO in step 902), this file is deleted (step 905), and the moving process of this file is terminated.

  FIG. 10 is a flowchart showing the file erasing / deleting process in the second embodiment.

  The file erasing / deleting process is executed asynchronously with the file moving process shown in FIG. 9 after the file moving process shown in FIG. 9 is completed.

  In this case, the service program that performs file erasure and deletion processing always monitors the file system, thereby performing file erasure processing and file deletion processing asynchronously with the file movement processing.

  In FIG. 10, when this file erasure / deletion process is started, it is first checked whether the file type to be erased is a directory (step 1001). If it is determined that the file type is not a directory (NO in step 1001), it is checked whether the file size of this file is 0 (step 1002). If it is 0 (YES in step 1002), the process proceeds to step 1010. However, if it is determined that it is not 0 (NO in step 1002), based on the file name of this file, an erasure process is performed to overwrite the data for erasure on the data entity of the file with this file name.

  In this erasing process, first, a preset erasing mode and the number of repetitions of the overwriting process in this erasing mode are acquired (step 1003).

  Next, data for erasure is obtained corresponding to the obtained erasure mode and the number of repetitions (step 1006), and an overwriting process is performed on the data entity of the file to be erased by the obtained erasure data (step 1006). .

  The acquisition of data for erasure in step 1004 and the overwriting process in step 1006 are repeated until it is determined in step 1004 that the erasure process is completed. If it is determined in step 1004 that the erasure process is completed (YES in step 1004). , Go to Step 1010.

  If it is determined in step 1001 that the file type to be erased is a directory (YES in step 1001), an erasure process is performed to overwrite the erase data on the data entity of each file in the directory. .

  In this deletion process, first, the file name of the file in this directory is acquired (step 1008), and the deletion process of the file in this directory is recursively executed based on the acquired file name (step 1009).

  The acquisition of the file name in step 1008 and the recursive execution of the erasure process in step 1009 are repeated until it is determined in step 1007 that the file in the directory is empty. In step 1007, the file in the directory is determined to be empty. Then (YES in step 1007), the process proceeds to step 1010.

  In step 1010, the file whose data entity is overwritten by the erasure data is deleted by the normal file deletion process provided by the system, and the file deletion and deletion process of the second embodiment is completed by this file deletion. To do.

  In the second embodiment, similarly to the first embodiment, when the processing is restarted by restarting or the like, the deletion target storage directory prepared in the top directory of each of the file systems 100-1 to 100-3 is searched and remains. By sequentially executing the erasure processing of the file data entity, the erasure processing of the file data entity can be performed without omission on the file to be erased. Since the processing in this case is the same as the processing of the flowcharts shown in FIGS. 7 and 8, detailed description thereof will be omitted.

  In the second embodiment, the file erasure / deletion process is performed asynchronously with the file movement process, so that the next process and the file entity erasure process can be performed in parallel, and a decrease in performance can be suppressed.

  In the second embodiment, the service program for deleting and deleting files is configured to always monitor the file system. However, the service program does not need to be constantly operated, and operates at regular intervals. Alternatively, the complete erasure process may be performed while ensuring the performance of the entire process by operating under the condition that the load on the device is low.

  In addition, a process for notifying the completion of the file erasure process may be added to the second embodiment so that the user can be notified of the completion of the erasure process as in the first embodiment.

  In the above embodiment, the case where only the file entity is deleted is described. However, not only the file entity but also information such as the file name stored in the file management area can be easily expanded. Conceivable.

  Although the above is an example of typical embodiment of this invention, this invention is not limited to the Example shown in the said Example and drawing, It can implement suitably deform | transforming within the range which does not change the summary. It is.

  The file erasing process can also be performed by processing with a central processing unit based on an image erasing program stored in the storage device.

  The image erasing program can be provided by being recorded on an external recording medium such as a CD-ROM or DVD as well as provided by communication means such as a network.
