At this point, the processing relating to the data file can be terminated. Therefore, it is possible to realize high-speed inspection regardless of the amount of data to be inspected.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing functional blocks of a data file detection apparatus 10 according to the present embodiment. The data file detection device 10 is a personal computer used in a company or at home, and as shown in the figure, comprises a storage means (including those related to a network drive) for storing a large number of data files such as a hard disk. Detection target data file storage unit 11, detection target file configuration information storage unit 12 (detection target file configuration information storage unit) that stores a program executed by the detection unit 14, and a file that stores one or more keywords , A keyword storage unit 13 that stores information, a detection unit 14 (detection unit) that reads and executes a program stored in the detection target file configuration information storage unit 12, and an output unit 15 that includes a display unit such as a liquid crystal display. It is equipped with.

  FIG. 2 is a specific example of a file storing keywords stored in the keyword storage unit 13. This figure is a file titled “Affiliated company”, and names of many affiliated companies are stored as keywords. By appropriately changing the keywords stored in this file, data files containing various types of information such as company information (information about business partners and related companies) and personal information (information about individual customers and employees) can be detected. become able to. Although the company name is a keyword in FIG. 2, a service name or a specific extension may be used as a keyword.

  The program stored in the detection target file configuration information storage unit 12 includes a plurality of detection target files selected in advance from a plurality of file configuration information (information constituting a data file such as properties, file names, extensions, file texts, etc.) The configuration information and the detection order information of the plurality of detection target file configuration information are incorporated. The detection target file configuration information storage unit 12 stores the program, so that a plurality of detection target file configuration information selected in advance from the plurality of file configuration information, information on the detection order of the plurality of detection target file configuration information, and Are stored in advance in association with each other.

  As specific file configuration information, here, four properties, file name, extension, and file body are used, and information indicating the order of property, file name, extension, and file body is used as the detection order information. Use. The specific contents of the file configuration information and the detection order are appropriately determined according to the type of keyword, and are determined so that the inspection speed is as high as possible while reliably detecting the data file. For example, if the keyword is related to company information, it is highly likely that a data file that contains the keyword in the property will contain company information, and the keyword in the property can be detected relatively quickly. It is preferable to start by detecting a keyword in the property.

  The detection unit 14 executes a program stored in the detection target file configuration information storage unit 12, thereby detecting predetermined detection target keywords in the detection target file configuration information corresponding to the detection order of the data file according to the detection order. If it is determined that the data file exists, the output unit 15 outputs information on the data file to be determined. If it is determined that the data file does not exist, the next detection of the data file according to the above detection order is performed. A process of repeatedly determining whether the detection target keyword exists in the target file configuration information is performed.

  3 and 4 are diagrams illustrating a processing flow of the detection unit 14 that operates according to the program. The operation of the data file detection apparatus 10 shown in FIG. 1 for performing high-speed data file inspection will be described below with reference to these drawings.

  When the start of the inspection is instructed by a user operation on an operation unit (not shown), the detection unit 14 starts detection processing. In the detection process, the detection unit 14 selects one data file stored in the detection target data file storage unit 11 one by one, and repeats the process from step S2 to step S18 for each data file (steps S1 and S19).

  When selecting the data file, the detecting unit 14 first selects a property as the detection target file configuration information (step S2). Next, the detection unit 14 sequentially selects keywords stored in the keyword storage unit 13 and determines whether or not the selected keyword is included in the detection target file configuration information (property) of the selected data file ( Steps S3 to S5). As a result, if the selected keyword is included in the detection target file configuration information (property), the detection unit 14 exits the loop process of steps S3 to S5, and moves the process to step S18. In step S18, the detection unit 14 causes the output unit 15 to display and output information on the selected data file (file name, information indicating the location in the hard disk (full path), update date, etc.), Select the data file. That is, if the selected keyword is included in the detection target file configuration information (property), the detection unit 14 stops the detection process for the selected data file at that time and starts the detection process for the next data file. To do.

  If the selected keyword is not included in the detection target file configuration information (property), the detection unit 14 next selects a file name as the detection target file configuration information (step S6). Subsequent steps S7 to S9 are the same as steps S3 to S5.

  If the selected keyword is not included in the detection target file configuration information (file name), the detection unit 14 next selects an extension as the detection target file configuration information (step S10). Subsequent steps S11 to S13 are the same as steps S3 to S5.

  If the selected keyword is not included in the detection target file configuration information (extension), the detection unit 14 next selects the file text as the detection target file configuration information (step S10). Subsequent steps S15 to S17 are the same as steps S3 to S5.

  As described above, the data file detection device 10 determines whether or not a detection target keyword exists in order for a plurality of detection target file configuration information, and relates to the data file to be determined when it is determined that it exists. The information is output, and the processing related to the data file is finished at this point. Therefore, compared with a case where a simple full-text search is performed, the inspection process can be completed at high speed even if the data amount of the data file to be inspected is large.
