The headquarters server stores in hot storage 11 the compliant evidence video data (mc1) which has been transmitted from the precinct server, and transmits the compliant evidence video data (mc1) to a receiving agency (PC65) of a receiving agency such as a court or a prosecutor's office.

Description

Evidence video management system and evidence video management method

This disclosure relates to an evidence video management system and an evidence video management method for transmitting video data captured as evidence video related to a case to the outside.

Conventionally, when an incident occurs at a police station, as the data related to the incident, a record of the incident that the police officer generated for each incident (for example, an investigation record generated when the police investigated the suspect in the incident), the police Surveillance images of predetermined locations in the station (for example, corridors and detention centers), investigation images of the investigation room provided in the police station, and the like were individually managed by being stored in different folders. For example, a police officer reads a paper medium of individually generated case records with a scanner in the police station, associates the case number with the document data file of the record obtained by the reading, and stores it in a default folder for document data. Registered and stored. In addition, the surveillance video data of the suspects captured by a surveillance camera installed at a predetermined location in the police station is organized for each incident, and another police officer (for example, a person in charge of a dedicated department in the police station). Are collectively managed in a default folder for monitoring video data. Furthermore, the interview video data showing the state of the suspect at the time of the interview taken by the surveillance camera installed in the interview room provided in the police station is similarly organized for each incident, and another police officer (for example, (A person in charge of a dedicated department in the police station) was collectively managed in the default folder for the interview video data. As described above, the monitoring video data and the interview video data are managed as evidence video data in a storage device in the police station.

Here, a medical record information management system shown in Patent Document 1 is known as a prior art that records and manages medical record records entered in a paper chart among a plurality of medical facilities in a batch. ing.

The examination record information management system of Patent Document 1 has a management server connected to a terminal device of each medical facility, and a scanner in which a paper chart generated by the terminal device of each medical facility is installed in each medical facility The image data is read and converted into image data, and stored in a paper chart information DB corresponding to each medical facility in the management server and shared.

In addition, as for police stations, there are a few countries or regions where the number of large-scale police stations to which many police officers belong (for example, the number of police officers is 500 or more) is small compared to the total number of police stations. Or in the area, there are overwhelmingly small police stations. Small police stations are scattered in various regions (eg, states, groups, prefectures, cities). Moreover, even if it is a large police station, since the jurisdiction range of one police station is wide, a large police station has many branch bases other than having a headquarters base, for example. In areas where small police stations are scattered, the number of police stations themselves is small, so the police station is a business other than the police station (eg, retail stores such as supermarkets, real estate companies that manage condominiums and apartments, banks Evidence video data on the incident is also collected from surrounding organizations. In recent years, with the spread of social media, the tendency of police stations to collect evidence video data from external surrounding organizations is rapidly increasing.

Under such circumstances, evidence video data managed by many small police stations, branch offices of large police stations, and external external organizations tend to increase year by year as incidents become more complex. . For this reason, it has been pointed out as a future problem that a large number of evidence video data is collected and stored at the headquarters base of a large police station, for example, and can be shared among many police stations. As a method for sharing evidence video data, the use of a cloud network is also being considered. In addition to being stored inside the police station, such evidence video data may be submitted to the court or the public prosecutor's office as necessary, so there is room for ingenuity in how to store and manage the evidence video data. There are thought to be.

Here, the evidence video data is generated using various video acquisition media (for example, a surveillance camera installed in the interrogation room, CCTV (Closed Circuit Television), fingerprint, SNS information, etc.), and thus various formats (that is, , Video data file format). For example, at the headquarters of a large police station, evidence video data recorded in such a variety of formats has been stored as it is. When evidence video data is submitted from the headquarters to the court or prosecutor's office in response to a request from the court or prosecutor's office, the court clerk or prosecutor's office prosecutor manually sets the format of the evidence video data to the default. Work to convert to standard format was done.

International Publication No. 2007/060856

However, the examination record information management system of Patent Document 1 is used in a medical facility. For example, a series of data obtained by reading a series of materials such as image data of a paper chart and a photograph taken that is referred to when the paper chart is entered. However, it was not considered to associate and manage a plurality of evidence video data related to one case like the police station described above. For example, it was not considered that large-scale police stations, small police stations, and external peripheral organizations aggregated and managed the evidence video data held for each case in an integrated manner.

Also, there are the following problems when evidence video data from many branch bases and external peripheral organizations are aggregated and shared. For example, when the headquarters base stores evidence video data in storage, the data capacity is enormous, so a large capacity storage is required, and the management cost increases. Also, when using a cloud network, the data capacity is enormous, so the billing increases according to the storage capacity, which also leads to an increase in management costs.

Also, in areas where branch offices exist, the number of access points is small, and communication is used in a narrow band with a low communication speed. Therefore, the communication time for uploading evidence video data becomes long and not efficient.

Also, manual format conversion by court clerk and public prosecutor's attorney at the prosecution office was a laborious work because of the huge amount of evidence video data. For this reason, in recent years, evidence video data submitted to courts and prosecutors' offices has been required to be in a standard format, and it has been necessary to meet this requirement.

The present disclosure has been devised in view of the above-mentioned conventional circumstances, and suppresses the management cost of a plurality of evidence video data and the storage capacity of storage related to incidents at individual police stations, and is the submission destination of evidence video data. Provided is an evidence video management system and an evidence video management method that easily generate evidence video data in a format that conforms to the requirements of the organization, reduce the processing load of transcoding processing, and ease restrictions on communication to the submitting organization. The purpose is that.

The present disclosure is an evidence video management system in which a first server device provided in a police station and a second server device provided outside the police station or outside the police station are connected to each other. The apparatus has a first storage unit, generates evidence video data by copying evidence video data relating to the case as original data, and generates compliance evidence that conforms to the specific format for the second evidence video data. Video data is converted and transmitted to the second server device, and evidence video data as original data is stored in the first storage unit. The second server device has the second storage unit and is submitted The compliance evidence video data transmitted from the first server device connected to the engine device is stored in the second storage unit, and the compliance evidence video data stored in the second storage unit is submitted at a predetermined timing. Evidence to send to engine equipment To provide an image management system.

The present disclosure is also an evidence video management method in an evidence video management system in which a first server device provided in a police station and a second server device provided outside the police station or the police station are connected. The first server device has a first storage unit, and generates second evidence video data by copying the evidence video data relating to the case as original data, and specifies the second evidence video data. Is converted into compliant evidence video data conforming to the format of the data and transmitted to the second server device, and the evidence video data as the original data is stored in the first storage unit, and the second server device stores the second storage device in the second storage device. The proof video data transmitted from the first server device is stored in the second storage unit and is stored in the second storage unit at a predetermined timing. Compliance evidence video data To send to the submission engine system, to provide the evidence video management method.

According to the present disclosure, it is possible to suppress the management cost of multiple pieces of evidence video data and the storage capacity of storage related to incidents at individual police stations, and meet the request of the submitting organization to which evidence video data is submitted. Evidence video data in a format can be easily generated, the processing load of transcoding processing can be reduced, and restrictions on communication to the submitting organization can be eased.

Hereinafter, an embodiment that specifically discloses an evidence video management system and an evidence video management method according to the present disclosure (hereinafter referred to as the present embodiment) will be described in detail with reference to the drawings as appropriate. However, more detailed description than necessary may be omitted. For example, detailed descriptions of already well-known matters and repeated descriptions for substantially the same configuration may be omitted. This is to avoid the following description from becoming unnecessarily redundant and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the claimed subject matter.

FIG. 1 is an explanatory diagram showing an example of a schematic configuration of the evidence video management system 5 of the present embodiment. The evidence video management system 5 shown in FIG. 1 includes a headquarter base system 10, a plurality of branch base systems 30, an in-vehicle camera system 50, and in-facility

facility camera systems

70 and 75 installed in peripheral facilities for each region. It has the composition which contains.

The headquarters base system 10 is a system for storing and managing a large amount of evidence video data that can be accessed by a PC (personal computer) installed in a police station. The headquarters base system 10 has a client server system installed in a police station (that is, a branch base system of each police station (for example, a small police station) as a client and a headquarters base system of a large police station as a server. System configuration) or an external network using a cloud network outside the police station. FIG. 1 shows a case where the headquarters base system 10 is constructed on the cloud network 8.

The headquarters base system 10 includes evidence video data uploaded and transmitted from each

branch base system

30A, 30B, 30C owned by each police station (for example, A police, B police, C police,... Information (see later) is received and stored in the hot storage 11. The hot storage 11 as an example of the second storage unit is a recording medium on which data is frequently read and written. When the headquarters base system 10 is configured using the client server system, the hot storage 11 is configured using the local hard disk 17 (see FIG. 2) or the network storage 14 (see FIG. 2). On the other hand, when the headquarters base system 10 is configured using the cloud network 8, the hot storage 11 is configured using a hard disk provided on the cloud network 8. Further, the headquarters base system 10 receives evidence video data uploaded from an in-vehicle camera system 50 described later, and stores it in the hot storage 11.

Also, the headquarters base system 10 may receive original evidence video data (hereinafter also referred to as original data) mo1 that is directly uploaded from the camera system 75 in each peripheral facility. In this case, the headquarters base system 10 generates evidence video data mo1 as two original data by copying the evidence video data mo1 as the original data, and uploads one original data (for example, directly from the camera system 75 in the surrounding facility). Obtained original video data) mo1 is stored in the cold storage 12, and the other original data (that is, video data that is duplicated data obtained by copying) mo1 is obtained by transcoding (automatic transcoding). The compliant evidence video data mc1 conforming to the standard format is stored in the hot storage 11. The cold storage 12 is a recording medium on which data is not frequently read or written (in other words, an archiver storage), for example, a Blu-ray disc (BDA: Blu-ray (registered trademark) Disc Association), a magnetic tape ( It is a recording medium suitable for long-term storage of data, such as LTO (Linear Tape-Open) and other optical disks. The peripheral facility camera system 75 is a security camera system installed in a peripheral facility such as a real estate company, a bank, a retail store, or the like that exists in an area where police stations are scattered.

The real estate company owns and manages the condominium, and since there are multiple surveillance cameras installed in the apartment, the situation at that time is imaged as evidence video when the suspect related to the incident hides or escapes. The In addition, because the bank keeps money, multiple surveillance cameras are installed in the bank, so when the suspect related to the incident robbed or threatens ordinary people or employees who are not directly related to the incident, the situation at that time Is captured as evidence video. In addition, retail stores are, for example, convenience stores, supermarkets, and department stores, and since multiple surveillance cameras are installed in the store, suspects related to the incident threaten cashier clerk at the cashier counter or run away from the store When doing so, the state at that time is captured as evidence video. As described above, according to the camera system 75 in each peripheral facility, although the outside of the police station, the suspect's identification or image of the suspect's case related to the case can be identified by the video of the beginning, midway, part-time, end-point, etc. It is possible to obtain video data that is likely to be important evidence for securing. In the present embodiment, evidence video data obtained from each peripheral facility camera system 75 is stored in the headquarters base system 10.

In the following description, transcoding is a process of converting the format of evidence video data (eg, extension of a moving image file format) as original data into a standard format (eg, MP4). However, the standard format is not limited to MP4, and may be WMV, for example. Evidence video data conforming to a standard format (compliant evidence video data) is data in which evidence video data as original data has a low resolution and is highly compressed, and the data size is further reduced compared to the original data. In the present embodiment, a moving image file format of “MP4” is used as a standard format. MP4 is a moving image file format compressed and encoded in the MPEG-4 format, and is suitable for data transfer using various wired and wireless networks. MP4 has a high affinity with general-purpose video editing software or video playback software, and is an easy-to-use video file format, so that video editing is easy. The transcoded standard format compliant evidence video data is also referred to as transcoded data.

When the transcoder processes the transcode and obtains the standard format evidence video data, it copies (duplicates) the evidence video data (first evidence video data) as the original data, and the evidence obtained by the copy Video data (second evidence video data) is converted into evidence video data that conforms (adapts) to a standard format. In addition, when the conversion source evidence video data remains after conversion, the transcoder may or may not discard it. Note that the transcoder may newly generate a compliant evidence video data compliant with the standard format based on the evidence video data of the original data without copying the evidence video data as the original data.

The branch base system 30 is installed in each small or large police station that has jurisdiction over each region, and stores a large amount of evidence video data in the cold storage 31. In FIG. 1, as a plurality of branch base systems 30, a branch base system 30A installed in the A police, a branch base system 30B installed in the B police, and a branch base system 30C installed in the C police are illustrated. In addition, when it is not necessary to distinguish

branch base systems

30A and 30B are surveillance cameras installed in various places (for example, interrogation rooms, detention centers, and corridors) in police stations of the A police and B police, and police cars on which police officers get on. Evidence video data mo1 is captured as original data imaged by an in-vehicle camera installed on the wearable device, a wearable camera worn or possessed by a police officer. The

branch base systems

30A and 30B generate a copy of the evidence video data mo1, transcode the evidence video data mo1 obtained by copying, and generate compliant evidence video data mc1 compliant with the standard format. 10 upload (send). At the same time as or after the upload, the

branch site systems

30A and 30B store the evidence video data mo1 as the original data in the cold storage 31, respectively.

In the C police, the branch base system 30C is connected to the plurality of peripheral facility camera systems 70 installed in the peripheral facilities of the C police through the network 71, and transmitted from the plurality of peripheral facility camera systems 70. A copy of the evidence video data mo1 as the original data is generated, and the evidence video data mo1 obtained by the copy is transcoded to generate the compliant evidence video data mc1 conforming to the standard format and uploaded (sent to the headquarters base system 10) ) At the same time or after this upload, the branch site system 30C stores evidence video data mo1 as original data in the cold storage 31. Each

branch base system

30A, 30B, 30C generates a report file RF1 simultaneously with or after the upload (transmission) of the compliant evidence video data obtained by transcoding and uploads (transmits) it to the headquarter base system 10. . The report file RF1 is a log information for the evidence video data as the original data or the compliant evidence video data obtained by transcoding, and processes for the evidence video data and the compliant evidence video data (for example, standardized by imaging, recording, and transcoding). This is a data file in which the history of compliance evidence video data conforming to the format, etc.) is described, and the storage location of the evidence video data as the original data is described. Details of the report file RF1 will be described later.

The in-vehicle camera system 50 records, for example, evidence video data mo1 as original data captured by an in-vehicle camera or a wearable camera in the field on an in-vehicle recorder, generates a copy of the recorded evidence video data mo1, and is obtained by copying. The evidence video data mo1 is transcoded to generate compliant evidence video data mc1 conforming to the standard format and uploaded to the headquarters base system 10. The in-vehicle PC uploads the compliant evidence video data mc1, which is transcoded data, and returns to the police station (for example, the A police). The original data (that is, the evidence video data mo1 recorded in the in-vehicle recorder) is received. It is registered (saved) in the branch site server 33 (see FIG. 3) of the branch site system 30 which is an on-premises server.

Further, the headquarters base system 10 is communicably connected to a submitting institution PC 65 as an example of an information processing apparatus used in a court or prosecutor's office (hereinafter referred to as submitting institution) which is a predetermined submitting organization. The submitting organization PC 65 of the submitting organization 60 submits (sends) to the headquarters base system 10 the compliance evidence video data mc1 conforming to a standard format corresponding to a certain case number and the report file RF1 corresponding to the compliance evidence video data mc1, for example. Request. In response to this request, the headquarters base system 10 sends the compliance evidence video data mc1 of the corresponding case number and the report file RF1 corresponding to the compliance evidence video data mc1 stored in the hot storage 11 to the submission organization of the submission organization 60 Send to PC65. In addition, the submitting organization PC 65 of the submitting organization 60 may request the headquarters base system 10 to submit, for example, evidence video data mo1 as original data corresponding to a certain case number. In response to this request, the headquarters base system 10 submits (transmits) the original data to the branch base system of the police station corresponding to the storage location of the original data described in the report file RF1 corresponding to the evidence video data mo1. Request. The corresponding branch base system submits the evidence video data mo1 of the relevant case number and the report file RF1 corresponding to the evidence video data mo1 stored in the cold storage 12 via the headquarter base system 10 to the submission organization 60. It transmits to engine PC65.

The in-vehicle PC 51 uploads the compliant evidence video data mc1 and then uploads the original data (that is, the evidence video data mo1 recorded in the in-vehicle recorder) to the branch base server 33 (or the headquarter base server 13) at an appropriate timing.

The operation of the evidence video management system 5 of the present embodiment having the above configuration will be described.

FIG. 5 is an explanatory diagram showing an example of an operation outline of the evidence video management system 5 of the present embodiment. Here, as an example of operation, the case of capturing evidence video data as original data recorded in an in-vehicle recorder is shown. However, evidence video data captured by a surveillance camera in a police station or evidence video captured in an interrogation room It may be a case of capturing data. Alternatively, evidence video data captured by the peripheral facility camera system 70 installed in the peripheral facility may be captured via the network 71. The branch base LP shown in FIG. 5 corresponds to the

branch base systems

30A, 30B, and 30C shown in FIG. 1, and the head office CP shown in FIG. 5 corresponds to the headquarter base system 10 shown in FIG.

In the branch office base LP, for example, when the police car CA returns to the police station (for example, the police A shown in FIG. 1), the police officer records the evidence video recorded in the in-vehicle recorder 57 of the in-vehicle camera system 50 mounted in the police car CA. The operation of fetching the data mo1 into the branch site server 33 is performed. The in-vehicle recorder 57 records both evidence video data as original data imaged by the in-vehicle camera 55 and evidence video data as original data imaged by the wearable camera 56. The in-vehicle PC 51 communicates with the branch base server 33 so that data can be transferred. Communication between the in-vehicle PC 51 and the branch site server 33 is performed by a wireless LAN (Local Area Network) or a wired LAN. In addition, the police officer can connect the devices using a USB (Universal Serial Bus) cable, or remove the memory card attached to the in-vehicle recorder 57 and attach it to the branch base server 33 to provide evidence video data. You may make it take in to the branch office server 33. FIG. When the branch base server 33 of the branch base LP takes in the original evidence video data mo1 recorded in the in-vehicle recorder 57, the branch base server 33 stores the original evidence video data mo1 in the cold storage 31 for archiver as the original data.

Further, the branch base server 33 generates a copy of the original evidence video data mo1, and converts the evidence video data mo1 as the original data obtained by the copying into the compliant evidence video data mc1 conforming to the standard format by the transcoder. . Further, the branch office server 33 generates a report file RF1 corresponding to the compliant evidence video data mc1, and describes the date and time converted into the standard format in the report file RF1. Further, the branch office server 33 calculates the hash value h of the evidence video data mo1 as the original data using the hash function, but the date and time when the hash value is calculated may be included in the report file RF1. The branch office server 33 uploads (transmits) the compliant evidence video data mc1, the report file RF1, and the hash value h compliant with the standard format to the head office server 13. When the in-vehicle PC 51 is directly connected to the headquarters base server 13, the in-vehicle PC 51 transmits the evidence video data mo1 as the original data recorded in the in-vehicle recorder 57 to the headquarters base server 13 without going through the branch base server 33. It is also possible.

On the other hand, at the headquarters base CP, when the headquarters base server 13 receives the compliant evidence video data mc1, the report file RF1, and the hash value h in conformity with the standard format, Compliant evidence video data mc1, report file RF1, and hash value h are stored. When the headquarters base server 13 receives the evidence video data mo1 as original data from the branch base server 33, the in-vehicle camera system 50, or the camera system 75 in the surrounding facility, for example, the local hard disk 17 or the network storage as the cold storage 12 14 stores evidence video data mo1 as original data.

Further, the headquarters base server 13 is communicably connected to a submitting institution PC 65 such as a court or a public prosecutor's office. When there is a request for submitting data relating to a case from the submitting institution 60, the head office server 13 responds to the request to the hot storage 11. The stored evidence video data mc1, report file RF1 and hash value h of the corresponding case number, or evidence video data mo1 as original data is transmitted to the submitting institution 60. When the evidence video data mo1 as the original data is transmitted to the submitting organization 60, the report file RF1 corresponding to the evidence video data mo1 may also be transmitted.

FIG. 6 is a diagram showing an example of recorded contents of the report file RF1 corresponding to the evidence video data. The report file RF1 is recorded as a log (history) so that the processing for each of the evidence video data mo1 and the compliant evidence video data mc1 becomes clear. In other words, the report file RF1 is generated not only for the evidence video data mo1 as the original data but also for the compliant evidence video data mc1 obtained by transcoding.

In the report file RF1, log information of processing for the evidence video data mo1 as the corresponding original data or the compliant evidence video data mc1 as the transcode data is recorded in chronological order from the top. Specifically, the log information includes processing date / time, processing content, GPS information, data file name, and the like.

For example, in the first log information LG1, “2015/8/28 15:00 recording GPS information file name” is recorded. This indicates that evidence video data was recorded at 15:00 on August 28, 2015 at a point indicated by GPS information (for example, a recording point).

In the second log information LG2, “2015/8/28 15:30 copy generation GPS information file name” is recorded. This indicates that the evidence video data was copied at 15:30 on August 28, 2015 at the point indicated by the GPS information (for example, the office of the A police station).

In the third log information LG3, “2015/8/28 18:00 converted to standard format, GPS information file name, original data storage location” is recorded. This is where the evidence video data is pointed to by GPS information (for example, the office of the A police station), transcoded at 18:00 on August 28, 2015, and compliant evidence video data conforming to the standard format is generated. The evidence video data as the original data is stored in the storage location.

In the fourth log information LG4, “2015/8/29 9:00 Uploaded GPS information file name to headquarters base” is recorded. This is a point indicated by GPS information (for example, the office of the police department A), and the compliant evidence video data generated from the evidence video data is sent to the headquarters base (see FIG. 5) at 9:00 on August 29, 2015. Indicates that it has been uploaded.

In the fifth log information LG5, “2015/9/2 10:00 GPS information file name transmitted to the Public Prosecutors Office” is recorded. This indicates that the compliance evidence video data was transmitted to the prosecuting agency PC 65 at 10:00 on September 2, 2015 at the point indicated by the GPS information (for example, the position of the headquarters base CP).

In the sixth log information LG6, “2015/9/4 18:00: Change of original data storage location, GPS information file name, original data storage location after change, branch base name” is recorded. This is the branch base name (for example, A police) of the point indicated by the GPS information, and the storage location of the evidence video data as the original data was changed to 18:00 on September 4, 2015, and the original data after the change Indicates that the storage location of is specifically described. The report file RF1 may be updated by overwriting each log information LG1 to LG6 or newly adding each log information. The report file RF1 may be stored in a configuration having a plurality of log information written in time series for each of the evidence video data mo1 and the compliant evidence video data mc1, or individual log information may be discretely stored. It may be saved. In the latter case, the CPU 35 of the branch base server 33 may be aggregated and generated in the format of the report file RF1 shown in FIG.

In addition, although an example of the report file RF1 corresponding to the evidence video data mo1 as the original data has been described in FIG. 6, the report file of the compliant evidence video data mc1 as transcode data generated from the evidence video data mo1 is obtained. In the report file RF1 shown in FIG. 6, there is no log information LG1. That is, the report file of the compliant evidence video data mc1 generated by the transcoding process is, for example, information corresponding to the log information LG2 (that is, information indicating that it is generated by copying the evidence video data mo1 as original data). Is listed at the top.

FIG. 7 is a flowchart showing an example of a procedure for uploading evidence video data in the evidence video management system 5 of the present embodiment. After the police officer records the evidence video data mo1 as the original data on the in-vehicle recorder 57 and returns to the police station (for example, A police) at the branch office base LP, the processing shown in FIG. 7 is started.

The branch office server 33 takes in the evidence video data mo1 as original data recorded in the in-vehicle recorder 57, and temporarily stores it in the local hard disk 37 or the network storage 34 (S1). The in-vehicle recorder 57 records evidence video data captured by the in-vehicle camera 55 and evidence video data captured by the wearable camera 56. Note that the branch office server 33 may capture the evidence video data directly from the wearable camera 56.

The branch base server 33 generates a copy of the evidence video data mo1 as the temporarily stored original data, and converts the evidence video data mo1 obtained by the copy into the compliant evidence video data mc1 as transcode data compliant with the standard format. (S2). The branch office server 33 temporarily stores the compliant evidence video data mc1 conforming to the standard format in the local hard disk 37 or the network storage 34. Further, the branch office server 33 generates each report file RF1 for the evidence video data mo1 and the compliant evidence video data mc1, and describes in each report file RF1 that the compliant evidence video data mc1 conforming to the standard format is generated. To do.

The branch site server 33 transfers and stores the evidence video data mo1 as the original data to the archive storage 31 for the archiver (S3). The branch base server 33 stores the evidence video data mo1 as the original data and the storage location of the original data in the report file RF1 of the evidence video data mo1.

The branch base server 33 uploads the compliant evidence video data mc1 compliant with the standard format and the report file RF1 corresponding to the compliant evidence video data mc1 to the headquarters base server 13 (S4). The headquarters base server 13 stores the uploaded compliance evidence video data mc1 and the report file RF1 corresponding to the compliance evidence video data mc1 in the local hard disk 17 or the network storage 14.

FIG. 8 is a flowchart showing an example of an original data acquisition procedure in the evidence video management system 5 of the present embodiment. In the processing shown in FIG. 8, after the compliant evidence video data mc1 compliant with the standard format is transmitted to the submitting organization 60 together with the report file RF1 corresponding to the compliant evidence video data mc1, the submitting organization 60, for example, The processing is started when it is determined that the evidence video data mo1 as the original data needs to be confirmed because the video is partially unclear due to the low resolution due to the high compression.

The submitting institution PC 65 used in the submitting institution 60 such as a court or a public prosecutor's office follows an input operation of a user (for example, a judge, a court clerk, a prosecutor, or a public prosecutor) who uses the submitting institution PC 65, for example, a serious crime In this case, it is determined whether or not the verification and verification of the evidence video data mo1 as the original data is necessary (S11). When it is determined that the evidence video data mo1 as the original data is not necessary (S11, NO), the processing of the submitting institution PC 65 shown in FIG. 8 ends. On the other hand, when it is determined that the evidence video data mo1 as the original data is necessary (S11, YES), the submitting institution PC 65 transmits an acquisition request for the evidence video data mo1 as the original data to the headquarter base server 13. (S12). This acquisition request includes information (for example, a file name) for identifying the evidence video data mo1.

Upon receiving the acquisition request transmitted from the submitting institution PC 65, the headquarters base server 13 accesses the local hard disk 17 or the network storage 14 to refer to the report file RF1 corresponding to the corresponding evidence video data mo1, and as the original data It is determined whether or not the storage location of the evidence video data mo1 has been updated (S13). That is, in the report file RF1, information on the storage location of the evidence video data mo1 as the original data once stored is described. However, the storage location of the evidence video data mo1 due to some circumstances (for example, consolidation of the police station) Is changed, the storage location of the original data after the change is described in the report file RF1 (for example, refer to the log information LG6 shown in FIG. 6), so that the storage location of the original data is checked by checking the report file RF1. Whether or not there is an update can be easily determined. If the storage location has not been updated (S13, NO), the headquarters base server 13 transmits an acquisition request for evidence video data mo1 as original data to the branch base server 33 (S14).

The branch office server 33 acquires the evidence video data mo1 as the original data stored in the cold storage 31, and returns it to the head office server 13 (S15). When receiving the evidence video data mo1 as the original data from the branch base server 33, the headquarters base server 13 transfers the evidence video data mo1 as the original data to the submitting institution PC 65. Thereafter, the processing shown in FIG. 8 returns to step S11.

On the other hand, if it is determined in step S13 that the storage location of the original data has been updated (S13, YES), the headquarters base server 13 acquires the updated report file RF1, and the branch base corresponding to the updated storage location The server 33 is specified, and further, an acquisition request for evidence video data as original data is transmitted to the specified branch site server 33 (S16). When the storage location of the evidence video data mo1 as the original data is updated, the branch base server 33 that has become the new storage location stores information on the new storage location in the report file RF1 corresponding to the evidence video data mo1. Is updated and automatically notified to the headquarters base server 13. The branch office server 33 that has become the new storage location acquires the evidence video data mo1 as the original data from the cold storage 31, and sends it back to the head office server 13 (S17). When the headquarters base server 13 receives the evidence video data mo1 as the original data from the branch base server 33 that is the new storage location, the headquarters base server 13 transfers the evidence video data mo1 as the original data to the submitting institution PC 65. Thereafter, the operation shown in FIG. 8 returns to Step S11.

As described above, in the evidence video management system 5 of the present embodiment, the branch site server 33 generates a copy of the evidence video data regarding the incident, and generates the evidence video data mo1 as two original data. The branch base server 33 transcodes the evidence video data mo1 as one of the original data to generate the compliant evidence video data mc1 conforming to the standard format, and uploads (transmits) the data to the headquarter base server 13. Further, the branch office server 33 stores the evidence video data mo1 as the other original data in the archive storage cold storage 31. Further, the headquarters base server 13 stores the compliance evidence video data mc1 transmitted from the branch base server 33 in the hot storage 11. The headquarters base server 13 transmits the compliance evidence video data mc1 stored in the hot storage 11 at a predetermined timing to the submitting organization PC 65 of the submitting organization 60 such as a court or a public prosecutor's office.

As a result, the evidence video management system 5 transcodes a copy of a plurality of pieces of evidence video data relating to the incidents at each police station, and transcodes the data after the low resolution and high compression processing (that is, the compliant evidence video conforming to the standard format). Data) is managed by the headquarters base server 13, it is possible to suppress the management cost of evidence video data as a plurality of originals and the increase in storage capacity of the storage. In addition, the evidence video management system 5 can easily generate evidence video data in a format (for example, MP4 in a video file format) that conforms to the request of the submitting organization to which the evidence video data is to be submitted. It is possible to reduce the processing load of transcoding processing that has been performed by manual input or the like, and to ease restrictions on communication to the submitting institution.

In addition, the branch base server 33 records various processing logs (history) for the compliant evidence video data mc1 and the storage location of the evidence video data mo1 as the original data corresponding to the compliant evidence video data in the cold storage 31. A report file RF1 is generated. The branch office server 33 uploads (sends) the report file RF1 to the headquarter office server 13 together with the compliant evidence video data mc1 compliant with the standard format. The headquarters base server 13 transmits the report file RF1 to the submitting institution PC 65. As a result, the submitting institution PC 65 confirms the history of the processing for the compliant evidence video data afterwards and manages the trail even if there is a problem such as the video of the compliant evidence video data mc1 being partially unclear and difficult to discriminate. It is possible to provide original data before low compression and high compression by obtaining evidence video data mo1 as original data. In this way, the storage location of the original evidence video data mo1 can be managed at all times. Therefore, when the submitting organization 60 such as a court or a public prosecutor's office needs the original evidence video data mo1, it can be surely acquired.

Also, the branch base server 33 calculates a hash value h of the original evidence video data mo1, and transmits the calculated hash value h to the headquarter base server 13 together with the compliant evidence video data mc1 conforming to the standard format. Thereby, the headquarters base server 13 can transmit the hash value h to the submitting institution PC 65 when it is requested to submit the hash value h from the submitting institution 60 such as trial and prosecution.

Further, the headquarters base server 13 transmits the hash value h to the submitting institution PC 65 in response to a request from the submitting institution PC 65. As a result, the submitting organization 60 such as a trial / prosecution can detect falsification and verify its validity when acquiring the original evidence video data mo1.

Further, when the storage location of the original evidence video data mo1 is changed, the branch base server 33 updates the report file RF1 and transmits the updated report file RF1 to the headquarter base server 13. Thereby, the evidence video data mo1 as the original data can be traced and confirmed later by the report file RF1, and the trail management becomes possible.

As mentioned above, although embodiment was described referring drawings, it cannot be overemphasized that this indication is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are of course within the technical scope of the present disclosure. Is done.

For example, in the above-described embodiment, MP4 is used as a standard format. However, the present invention is not limited to this, and a moving image file format such as MOV, AVI, WMV, FLV or the like is used based on a request from a court or a public prosecutor's office. Also good. Evidence video data can be managed taking advantage of the features of each video file format.

In the above-described embodiment, the evidence video data is exemplified. However, the present invention is not limited thereto, and may be still image data, document data, drawing data, and the like, and various data can be managed.

In the above-described embodiment, the compliance evidence video data mc1 or the evidence video data mo1 as the original data does not necessarily have to be shared between the headquarters base system 10 and the submitting institution PC 65 via the network. For example, the compliant evidence video data mc1 or the evidence video data mo1 as original data may be copied to a physical medium such as a DVD (Digital Versatile Disk) and physically shared from the headquarters base system 10 to the submitting institution 60. . Thereby, the sharing of the evidence video data mc1 or the evidence video data mo1 as the original data (ie, bidirectional data exchange) is substantially possible between the headquarters base system 10 and the submitting institution PC 65.

Further, in the above-described embodiment, the submitting organization PC 65 of the submitting organization 60 may request only the compliant evidence video data mc1 conforming to the standard format corresponding to a certain case number, for example, from the headquarters base system 10. In this case, as described in the above-described embodiment, the headquarters base system 10 sends the report file RF1 (for example, the original document) corresponding to the compliance evidence video data mc1 and the compliance evidence video data mc1 to the submission organization PC 65 of the submission organization 60. If the log data including the storage location of the evidence video data mo1 as data is transmitted, the same effect as the present embodiment can be obtained.

This disclosure can reduce the management cost of multiple evidence video data and the storage capacity of storage for incidents at individual police stations, and is in a format that meets the requirements of the submitting organization to which evidence video data is submitted. Evidence video data can be easily generated, and is useful as an evidence video management system and an evidence video management method for reducing the processing load of transcoding processing and reducing restrictions during communication with a submitting organization.
