Therefore, since an incentive to pay sufficient attention not to leak the image file 60 to the applicant or manager who manages the image file 60 is advantageous, the possibility of leakage of the image file 60 is lowered. In addition, since the identity information of the applicant can be confirmed in the leaked image file 60, it is easy to confirm at which point the image file 60 is leaked, and there is an advantage of strengthening the security of the leaked point.

When the applicant terminal 30 is connected to the main server 20, the interface provider 220 may provide a web page for the video export application to the applicant terminal 30. The process described below may be performed on a web page or an interface provided by the interface provider 220.

First, the applicant terminal 30 performs the video export application step (S20) for requesting the video export by accessing the main server 20. 6 is a flowchart illustrating a process of creating a video export application to use a video export service according to an embodiment of the present invention.

The export application management unit 240 of the main server 20 may provide an application form including input items necessary for an image export application to the applicant terminal 30 (S21). Input items include CCTV location, CCTV name, CCTV shooting time, reason for exporting video, viewing range for information on the person who wants to view the video, start and end date for viewing the video, and to view the video. And other information for determining whether to approve an image export application or other information for generating an image file 60.

In the video export application step, the operation method of the main server 20 for providing a video export service according to an embodiment of the present invention, the applicant terminal 30 so that the applicant can specify the person to view the image file 60 In accordance with the request of the applicant or the information of the pre-registered may be transmitted to the applicant terminal 30, the reading range set by the applicant from the applicant terminal 30 may further include a reading range setting step (S22). .

Reading range setting step (S22) may be performed in the middle of creating a video export application (S20). In order to input the reading range, the applicant terminal 30 may input the reading range by selecting one of the persons registered in the main server 20. That is, when there is a request from the applicant terminal 30, the video export management unit of the main server 20 may provide the applicant terminal 30 to select a list of related persons registered in the member DB 231.

The application for exporting images may be defined by the applicant or at least one related person designated by the applicant to view the image file 60. The scope of access may be only the applicant, at least one relevant party designated by the applicant and the applicant, or at least one relevant party designated by the applicant. In this case, the applicant or the related person may be an employee of an investigation agency such as a police or a prosecution or a worker of a public institution such as a court or a ward office.

The applicant terminal 30 receives the applicant's input for the input item (S23). When the applicant terminal 30 applies the video export request by providing input items necessary for the video export application input by the applicant to the main server 20, the main server 20 receives the video export request (S24). When the video export request is received as a document, the main server 20 receives the input items necessary for the video export application input by the administrator from the administrator terminal 50, so that the main server 20 receives the video export request. (S24).

Next, referring back to FIG. 5, the main server 20 may perform an approval determination step (S30) of determining whether to approve the image export application. Depending on whether or not the approval, the main server 20 may send the approval notification or unapproved notification to the applicant terminal (30). 7 is a flowchart illustrating an approval determination step S30 of determining whether to approve an image export application according to an embodiment of the present invention.

The export application management unit 240 of the main server 20 determines whether the video export application can be automatically approved or not, based on the input items of the received image export application, or whether the individual approval of the administrator is necessary ( S31). If the video export application can automatically determine whether to approve or not, the export application management unit determines whether to approve or not based on the entry of the input item (S32). If the video export application requires individual approval of the manager, the export application management unit 240 transmits the content of the video export application to the manager terminal 50 (S33), and the manager terminal 50 exports the video input from the manager. If the approval of the application is transmitted to the main server 20 (S34), the export application management unit 240 determines whether to approve or not according to the approval received through the manager terminal (50).

Next, referring back to FIG. 5, when the video export application is approved, the main server 20 may perform an image file generation step S40 of generating an image file 60 including the identity information of the applicant. have. 8 is a flowchart illustrating an image file generation step and an export step according to an embodiment of the present invention.

The image file generation step (S40) is a step of receiving an image according to the image export application from the image management server 10 (S41), masking step of generating a masked image by masking the personal information shown in the image (S42), masking It may include the step (S43) for generating an image file 60 including the image and the identity information of the applicant.

The image file generator 260 of the main server 20 may request an image of a CCTV to be viewed by the applicant to the image management server 10 based on an input item of the image export application. When the video management server 10 receives a video request from the main server 20, the video management server 10 may automatically transmit the video to the main server 20. Alternatively, when the video management server 10 receives a video request from the main server 20, the video management server 10 provides the content of the video request to the manager terminal 50, and whether the manager terminal 50 allows the manager to input the video. When transmitting to the management server 10, the requested image can be provided to the main server 20 according to whether the administrator input. Through this process, the main server 20 may receive an image according to the image export application from the image management server 10 (S41).

The masking unit 261 of the image file generating unit 260 performs a masking step (S42) of generating a masked image by masking personal information displayed on the image. In the masking step, the masking unit 261 masks personal information corresponding to a person's privacy, such as a face, a license plate, and a phone number, according to a predetermined algorithm. The image received from the image management server 10 may be separately stored in the image storage unit 340 as an original image, and an image masking personal information may be separately generated.

The encryption unit 262 of the image file generator 260 generates an image file 60 including the masked image and the identity information of the applicant (S43). The encryption unit 262 encrypts and generates the image file 60 including the header 610, the DRM meta 620, and the data so that only the dedicated viewer 70 can play it. The image masked by the masking unit 261 may be included in the data 630 portion of the image file 60. According to the viewing information included in the image export application, the identity information of the applicant or the related person may be included in the DRM meta 620. For example, the identity information of the applicant may be the applicant ID or the applicant's name, which may be included in the location of the viewer ID and the viewer's name of the DRM meta 620 of the image file 60. Identity information of the applicant or related persons included in the image file 60 may be encrypted so that it cannot be arbitrarily read, changed or modified.

9 is a block diagram showing the number of cases of an image file generating step according to an embodiment of the present invention.

Specifically, the image file generation step generates an image file 60 containing only the identity information of the applicant when the viewing scope is only the applicant, and the applicant's identity information and related persons when the reading range is the applicant and at least one person designated by the applicant. Creates a video file 60 that includes the identity information of the, or generates a plurality of video files 60 each containing the identity information of the applicant or related parties, and if the viewing range is a plurality of related parties specified by the applicant The image file 60 including the identity information of the relevant person may be generated, or the plurality of image files 60 including the identity information of the plurality of related parties may be generated.

If the viewing scope is only the applicant (CASE 1), it is sufficient to insert only the applicant's identity information into the image file 60 because only the applicant's identity information will be checked if the image file 60 is leaked to an unauthorized person. .

On the other hand, if the viewing range is the applicant and at least one relevant person designated by the applicant (CASE 2), there is a fear that the image file 60 is leaked to the unauthorized person from the applicant or at least one relevant person designated by the applicant. Therefore, in order to track the leakage point, if the image file 60 including the applicant's identity information and the image file 60 including the identity information of the at least one person designated by the applicant are separately generated and transmitted, the leaked to an unauthorized person By checking the image file 60, it can be confirmed from whom the image file 60 leaked. For example, an image file 1 including only the identity information of the applicant and an image file 2 including only the identity information of the related party 1 may be separately generated. Of course, the image file 60 may be generated by including the identity information of a plurality of persons in one image file. Of course, the image file 60 may be generated by including both the identity information of the applicant and the identity information of at least one related person designated by the applicant in one image file 60.

In addition, when the viewing range is a plurality of related parties specified by the applicant (CASE 3), in order to track which leakage occurred in which related parties, the number of video files 60 as many as related persons may be separately generated and transmitted. For example, an image file 1 including only the identity information of the person concerned 1 and an image file 2 including only the identity information of the person concerned 2 may be separately generated. Of course, the image file 60 may be generated by including the identity information of a plurality of persons in one image file.

Next, the export application management unit 240 of the main server 20, the transport step (S50) for transmitting the dedicated viewer 70 for playing the video file 60 and the video file 60 to the applicant terminal 30 Can be performed. Applicants or related persons included in the viewing scope of the video export application and approved for the video export application are connected to the main server 20 using the applicant terminal 30 or the related user terminal 40 to view the image file 60 and the dedicated viewer ( 70) can be downloaded. When the main server 20 receives a signal for requesting the image file 60 and the dedicated viewer 70 from the applicant terminal 30 or the related terminal 40, the main server 20 receives the video to the applicant terminal 30 or the related terminal 40. The file 60 and the dedicated viewer 70 are transmitted. In this case, the applicant terminal 30 may be transmitted to the image file 60 including the applicant's identity information, the relevant terminal 40 may be transmitted to the image file 60 containing the identity information of the relevant person (Fig. 9).

Through the above-described process, the main server 20 may receive an image export request from the applicant terminal 30, determine whether to approve, generate an image file 60, and provide the image file 60 to the applicant terminal 30. On the other hand, the step of transmitting the image file 60 and the dedicated viewer 70 from the above-described image export application step may be performed more than once for one image. For example, when the viewing scope was only the applicant in the first video export application, the applicant may apply for a second video export with only the interested persons as needed to view the image file 60 to the relevant persons. The second image export application may be performed by repeating the above-described process as it is, or if the application for exporting the same image is omitted, the masking step may be omitted. The image file 60 generated according to the second image export application is generated to include the identity information of the persons listed in the reading range of the second image export application.

On the other hand, the operation method of the main server 20 for providing a video export service according to an embodiment of the present invention, in order to provide a video export service with a playback restriction, it is possible to play with the video according to the applicant's video export application An image file generating step (S40) of generating an image file 60 including reference information including at least one of the number of times or the license expiration date, and a dedicated viewer capable of playing the image file 60 and the image file 60 ( 70 may include an export step (S50) for transmitting to the applicant terminal (30).

At this time, the dedicated viewer 70 is executed in the applicant terminal 30, and if the number of times of reproduction of the video file 60 recorded in the dedicated viewer 70 is less than the number of possible playbacks included in the reference information, it is in a playable state. Inspecting the number of times of playback to judge, When the current time has not passed the license expiration date included in the reference information, Inspecting the duration of play to judge the playable state, or When the current time is before the last playing time recorded in the dedicated viewer 70 At least one of the time manipulation checks to determine that the current time has been manipulated and is determined to be in a non-reproducible state, and reproduces the image file 60 only when determined to be a playable state, the dedicated viewer 70 The detailed operation of the applicant terminal 30 or the related party terminal 40 will be described later.

First, the export application management unit 240 of the main server 20 receives the image export request (S24) and then performs the approval determination step (S30) to determine the reference information when the image export application is approved (see FIG. 7). . The reference information is set in advance in the main server 20 before the applicant terminal 30 or the person concerned terminal 40 receives the image file 60 from the main server 20. Export application management unit 240, based on the contents described in the input items of the video export application, whether to capture the image included in the DRM meta (620 of FIG. 6) (is_allow_capture) of the image file 60, whether or not integrity hash extraction ( Standard information such as is_extract_integrity_hash, re-export (is_reexport), play count (play_count), license start date (req_license_start_date), license expiration date (req_license_end_date), encryption key (encrypt_key) and unique value (unique_vlaue) can be determined automatically. . Or, if it is necessary to determine the administrator, the export application management unit 240 may receive the reference information input by the administrator to the manager terminal 50 to use as reference information.

When the export application management unit 240 determines the reference information based on the input item, when it is determined that further checking whether the terminal using the eigenvalues is necessary, the export application management unit 240 requests the user to export the video to the reference information. In addition, the unique value of the applicant terminal 30 obtained by the eigenvalue extraction unit 250 of the main server 20 may be further included. At this time, the dedicated viewer 70 compares the eigenvalues included in the reference information with the eigenvalues extracted from the applicant terminal 30 on which the dedicated viewer 70 is executed, and judges that they are reproducible in the same case. It may be further determined that the terminal match check to determine that the non-replayable state by determining that the terminal is not.

That is, the reference information is a value determined by the main server 20 based on the input item of the video export application in order to provide a video export service with playback restrictions. For example, a license start date and an expiration date of reference information may be determined based on a start date and an end date for viewing an image of an input item, and a playable number of reference information may be determined based on the number of times the image is to be viewed.

Next, when determining the reference information in the export application management unit 240, in the image file generation step (S40), receiving the image according to the applicant's video export application from the image management server 10 (S41), to the video The masking step (S42) of generating the masked image by masking the displayed personal information, and the step (S43) of generating the image file 60 including the masked image and the reference information. Receiving an image according to the applicant's video export application (S41) and masking step (S42) is the same as described above.

The encryption unit 262 of the image file generator 260 performs an operation S43 of generating an image file 60 including the masked image and reference information. The encryption unit 262 can play the image file 60 including the reference information in the DRM meta 620 portion of the image file 60 and the image masked in the data 630 portion only in the dedicated viewer 70. Create it by encrypting it. The reference information included in the image file 60 may be used when the applicant terminal 30 or the related person terminal 40 determines whether or not it is playable through the dedicated viewer 70.

Through the above-described process, the main server 20 may generate an image file 60 including reference information on the reproduction restriction. Next, the export application management unit 240 of the main server 20, the transport step (S50) for transmitting the dedicated viewer 70 for playing the video file 60 and the video file 60 to the applicant terminal 30 Can be performed.

10 is a view showing the operation of the applicant terminal 30 using the image export service according to an embodiment of the present invention. In this specification, the operation of the applicant terminal 30 will be described as a reference, but the affiliated terminal 40 may also operate in the same manner.

Applicant terminal 30 operating method using the image export service according to an embodiment of the present invention, receives the image file 60 and the dedicated viewer 70 for playing the image file 60 and the dedicated viewer ( 70 to execute (S110), the dedicated viewer 70 determines whether to play the image file 60 on the basis of the reference information included in the image file 60 (S120) The reproduction may include a reproduction step S130 of reproducing the image file 60 only when it is determined that the reproduction is possible.

In the export step (S50), the applicant terminal 30 downloads the image file 60 and the dedicated viewer 70 from the main server 20. The applicant terminal 30 may store the downloaded image file 60 and the dedicated viewer 70 in the storage unit 340. The applicant terminal 30 may receive the applicant's input through the input unit 320, and the controller 350 may execute the dedicated viewer 70 (S110). If the dedicated viewer 70 is included in the installation program (installation package) that needs to go through the installation process, the dedicated viewer 70 is executed by executing the installation program including the dedicated viewer 70 before executing the dedicated viewer 70. You can also perform the installation steps first.

When the applicant terminal 30 executes the dedicated viewer 70, the graphic object provided by the dedicated viewer 70 is displayed to the applicant through the display unit 330 of the applicant terminal 30. When the applicant terminal 30 receives an input for reproducing the image file 60 using the dedicated viewer 70 from the applicant (S111), the dedicated viewer 70 executed by the control unit 350 is decoded (S112). Can be performed. The decryption unit 710 of the dedicated viewer 70 decrypts the image file 60 encrypted with the DRM standard using the same DRM standard.

Next, the playability determination unit 730 of the dedicated viewer 70 performs the playability determination step (S120). Determining whether or not the playback time is the playback time check step (S121), the current time is determined to be in the playable state when the number of times the playback of the image file 60 recorded in the dedicated viewer 70 is less than the playable number of the reference information If the license expiration date of the reference information has not passed, it is determined that the playback time is determined to be playable (S122), or if the current time is before the last playback time recorded in the dedicated viewer 70, the current time is determined to have been manipulated. It may include at least one of the time operation whether the operation check step (S123) to determine the non-renewable state.

The playback count check step (S121) determines that playback is impossible if the playback count of the reference information determined by the main server 20 is equal to the playback count of the video file 60 recorded in the dedicated viewer 70. The playback record storage unit 750 of the dedicated viewer 70 records the number of playbacks separately when the video file 60 is played back (S140). For example, when the image file 60 is played five times by using the dedicated viewer 70, the number of times the play record storage unit 750 is played is five, and the number of times that the image file 60 can be played is five. In the case of one time, the same video file cannot be played because all the number of times that can be played are used. Such a limit on the number of times of reproduction prevents the leakage of personal information as much as possible by not allowing the authorized person to play the image file 60 photographing an unspecified number of people more than a predetermined number of times.

In the playback period inspection step S122, when the current time passes the license expiration date of the reference information, it is determined that the playback time is not playable. In the playback period inspection step (S122), the playability determination unit 730 of the dedicated viewer 70 checks the current time by accessing a time server on a wired or wireless network. A time server is a server that provides a reference time on the Internet. If the current time is confirmed, the playability determination unit 730 compares the license expiration date included in the reference information of the image file 60 with the current time. If the current time is earlier than the license expiration date, the license has not been expired and is determined to be playable. If the current time is later than the license expiration date, the license has expired and is determined to be non-renewable. Such a reproducing period limit prevents the leakage of personal information as much as possible by preventing the unauthorized reproduction of the image file 60 photographing an unspecified number of people, even if approved.

In the time operation checking step S123, when the current time is earlier than the last playback time recorded in the dedicated viewer 70, it is determined that the current time has been manipulated and thus cannot be reproduced. The time manipulation test step may be performed when the play availability determination unit 730 cannot access the time server on the wired or wireless network in the play period test step. For example, when the current time has passed the license expiration date, the applicant terminal 30 blocks access to the wired / wireless network and changes the time of the applicant terminal 30 itself to before the license expiration date to manipulate the time. There may be. In this case, if the current time acquired by the applicant terminal 30 is used in the reproduction period checking step, an error may be determined to be in a playable state. However, in this case, in the time manipulation test step, the reproducibility determination unit 730 determines the last reproduction time when the current time obtained from the applicant terminal 30 is recorded in the reproduction record storage unit 750 of the dedicated viewer 70. If it is faster, since the current time is manipulated, it may be determined that it is impossible to reproduce, thereby limiting the reproduction using the applicant's time manipulation. Such a reproducing period limit prevents the leakage of personal information as much as possible by preventing the unauthorized reproduction of the image file 60 photographing an unspecified number of people, even if approved.

The reproducibility determination unit 730 may perform at least one or more of the reproducing count check step (S121), the reproducing period check step (S122), and the time manipulation check step (S123) described above in the reproducibility determination step (S120). You can do it all. If it is determined that playback is not possible, the reproduction decision unit 730 may perform the step S150 of deleting the image file 60 to delete the image file 60. When it is determined that the state cannot be reproduced, the image file 60 may be deleted to prevent the image file 60 from leaking.

Applicant terminal 30 operating method using the image export service according to an embodiment of the present invention, by comparing the eigen value included in the reference information and the eigen value extracted from the applicant terminal 30 running the dedicated viewer 70 If it is the same, it may further include a terminal matching check step (S124) to determine a playable state, and in other cases judged to be a non-playable state by determining that it is not the applicant's terminal. The terminal match check step (S124) may be performed by being included in the play decision determination step. Alternatively, only terminal matching test step S124 may be performed separately. The terminal match check step (S124) may be performed by the playback decision unit 730 of the dedicated viewer 70.

The terminal match check step (S124) is a step of determining whether to perform a terminal match check step based on information such as display of whether the eigenvalues included in the image file 60 or the terminal match check step performed, dedicated viewer ( Acquiring a unique value of the applicant terminal 30 using the eigenvalue extractor 720 of the 70, the eigenvalues obtained by the eigenvalue extractor 720 of the dedicated viewer 70 and the image file 60 Comparing the eigenvalues included in the reference information of the determination may be determined to be a playable state, and if there is a mismatch may include a comparison step of determining that the state of the applicant is not a playable state.

In the step of determining whether to perform the terminal matching check step, the playability determination unit 730 determines that the terminal matching check step is performed when the unique value is included in the DRM meta 620 of the image file 60. If the eigenvalue is not included, it may be determined that the terminal matching check step is not performed. Alternatively, when the main server 20 generates the image file 60, it may indicate whether to perform a terminal matching check step on the DRM meta 620 of the image file 60, the applicant terminal 30 The playability determination unit 730 of the dedicated viewer 70 to be executed in the determination of whether to perform the terminal matching check step according to the display whether the terminal matching check step performed in the DRM meta 620 of the image file 60 You may.

Next, in the step of obtaining the eigenvalue of the applicant terminal 30, the eigenvalue extractor 720 of the dedicated viewer 70 in the same manner as performed by the eigenvalue extractor 250 of the main server 20 The unique value of the applicant terminal 30 may be obtained. For example, the unique value may be a value generated based on the computer name and the MAC address information of the applicant terminal 30.

Next, in the step of comparing the eigenvalues obtained by the eigenvalue extracting unit 720 of the dedicated viewer 70 with the eigenvalues included in the reference information of the image file 60, if the eigenvalues match, the image file. Since viewing 60 is to play the video file 60 on the same terminal as the applicant's terminal 30 of the approved applicant, it is determined that the reproduction is possible. If the inherent value is inconsistent, since viewing the video file 60 is to play the video file 60 in a terminal other than the approved applicant's terminal, the video file 60 is leaked or an unauthorized person It is determined that the file 60 is to be viewed, and is determined to be in a non-reproducible state.

By performing the terminal matching check step (S124), the applicant or the related person who is authorized to view the image file 60 can be prevented from playing the image file 60 by using another terminal, and thus exists in another terminal. There is an advantage to avoid the risk of leakage, such as hacking can be, and even if the image file 60 is leaked to the outside can not be played on the other terminal leakage of personal information from the image file (60) photographing an unspecified number of people It is effective to prevent as much as possible. If it is determined that the state is impossible to play in the terminal match determination step, the zero deletion step (S150) for automatically deleting the image file 60 may be performed.

As described above, the dedicated viewer 70 executed in the applicant terminal 30 or the related terminal 40 checks the number of playbacks, playback period, and time operation based on the information included in the image file 60. Since the terminal match check is performed, the video file 60 is played within a predetermined number of times, a license period, and a limited range of the specified terminal. Therefore, if the playback limit is not exceeded, it is not reproduced, thereby preventing the unspecified number of personal information included in the image file 60 from leaking to the outside as much as possible.

Furthermore, when the image file 60 includes identification information of the applicant or related person authorized to view the image, and includes the information about the number of times of play, the license period, and whether the terminal is designated, the approval is approved. Even if the image file 60 is leaked to the unreceived person, it can be restricted from being played. If the leaked image file 60 is obtained from an unauthorized person, the identification information contained in the image file 60 is leaked. You can see where the branch is.
