Crime prevention environment design is a design method for creating an environment that is strong against crime prevention by strengthening the building of the building after grasping the current situation for crime prevention measures and at the same time constructing a psychological defense castle wall.
The crime prevention environment design is designed by a crime prevention environment design element based on, for example, the SP (Safer Place) 7 principle introduced in the United Kingdom.
The SP7 principles are (1) Access and movement, (2) Surveillance, (3) Ownership, (4) Physical protection, (5) Activity ( Activity), (6) Management & maintenance, and (7) Structure.
In the crime prevention system 1 according to the present embodiment, for example, it is considered that information such as (2) monitorability, (3) consciousness of ownership, (6) maintenance and management can be collected from local residents possessing mobile terminals. .

“Monitoring” refers to “natural monitoring” in which the eyes of passersby and residents are poured into specific spaces from roads and buildings, “mechanical monitoring” such as surveillance and recording by security cameras, patrol by police and residents, and security. It can be divided into three types of “organizational monitoring” by employees. Here, it is considered that information relating to the subjectivity of local residents who possess mobile terminals can be collected for nature monitoring.
That is, the information related to the subjectivity of the local residents includes, specifically, whether the current position of the owner of the mobile terminal 10 is bright, whether it is scary, whether the traffic is heavy, whether the traffic is heavy, This refers to information on the subjectivity of local residents regarding whether or not there is a blind spot, whether there is a blind spot, whether there is monitoring from the surroundings, and so on.

“Attitude of belonging” refers to the feeling of attachment, responsibility, and community feel to the area to which local residents belong.
In the crime prevention system 1 according to the present embodiment, it is considered that the sense of belonging can be measured by the total amount of information collected from local residents.

  “Maintenance” refers to information on whether the maintenance status of facilities, etc. and the cleaning status are properly maintained. Specifically, the maintenance status of planting, etc. and the presence of graffiti and garbage This refers to information about the subjectivity of local residents about the situation.

A security application for the security system according to the present embodiment is installed in advance on the mobile terminal 10 possessed by a resident or the like belonging to a specific local government.
The security application is not limited to the configuration installed in advance in the mobile terminal 10, and may be configured to download the application for the mobile terminal each time the security application on the security system server 30 is accessed. Good.
Depending on the security application, a voting screen as shown in FIG. 3 is periodically displayed, or the voting screen is displayed by its own operation.
On the voting screen, the items relating to the aforementioned “monitorability” and “maintenance / management” are displayed by an alternative method or the like, and a selection button is displayed beside each item.
The owner of the mobile terminal 10 inputs information by selecting (inverting) a selection button of an item that matches his subjectivity among items displayed on the voting screen.

The signal processing unit 105 generates a transmission signal from information input by the user of the mobile terminal 10, but at this time, the transmission date and time, the attributes of the user, and the like may be included in the transmission signal. This is because the answers may vary depending on the time of day, the owner's perspective, and the age.
In addition, the above-described position information signal is also transmitted together with the crime prevention information signal. However, since the owner of the mobile terminal 10 may detect the danger and input after moving, the present embodiment relates to this embodiment. It is desirable that the security application for the security system is configured to have a position specifying function. Specifically, by launching the location specification function of the security application, a map centering on the current location at the time of voting is displayed on the screen of the mobile terminal, and the location related to the security information to be input is selected on the map. It is more desirable to use a position information signal. This is because it becomes possible to transmit the crime prevention environment information for the position information more accurately.

  The transmission signal generated by the signal processing unit 105 of each mobile terminal 10 is wirelessly transmitted by the transmission / reception control unit 104 and the communication antenna 105, and is transmitted to the data server via the base station 11, the base station control unit 12, and the Internet 50. 30.

As shown in FIG. 4, the data server 30 is configured by a computer in which the communication interface 301, the CPU 302, the RAM 303, the hard disk 304, the ROM 305, the input / output interface 306, and the like are connected via an internal bus 307.
In the present embodiment, the hard disk 304 stores a security map creation program according to the present invention, and the CPU 302 executes the program.
The RAM 303 is used as a working memory that stores data when the CPU 302 executes a program.
The hard disk 304 has a storage area for storing crime prevention environment information, and the crime prevention environment information transmitted from each portable terminal is accumulated.
The ROM 305 stores a minimum value (threshold value) of the number of votes for determining whether or not crime prevention environment information described later is displayed on the map.

The data server 30 aggregates data related to the same point and the same time zone in the same area among the data stored in the hard disk 304 by executing the security map creation program. And the crime prevention map which made the count result display on the map information of the area is created.
And the data server 30 transmits the information signal regarding the produced crime prevention map with respect to the portable terminal 10 previously registered through the internet.

The information signal related to the crime prevention map includes local map information relating to the crime prevention map, the content of crime prevention environment information displayed on the crime prevention map, and location information of points relating to the information.
The mobile terminal 10 that has received the information related to the security map can display the security map based on the received information signal related to the security map on the security application.
Further, an information signal related to the crime prevention map may be transmitted to the information terminal 40 installed in the local government, police, school, etc., connected to the Internet 50 via the communication interface 41.
The information terminal 40 that has received information related to the security map can share the security environment information including the security map by enabling local residents who have registered in advance to view it, and also print the security map. Distributing the information can provide information on crime prevention to many local residents.

FIG. 5 shows a display example when the mobile terminal 10 or the information terminal 40 receives data from the data server 30 and displays a security map on the display screen.
In the crime prevention map displayed on the mobile terminal 10 or the like, an arbitrary icon is displayed at the point where the vote is received from the mobile terminal 10 (FIG. 5A).
When an operator of the portable terminal 10 or the like moves the cursor to a point where the icon is displayed or selects the point by using an arrow key in order, a pop-up window is opened. Detailed information related to the crime prevention environment information based on the voting results is displayed (FIG. 5B).
The icon may change color depending on the number of votes.

Specifically, the display content of the pop-up window may display crime prevention environment information including an item voted for each point and time zone and the number of votes for the item. Alternatively, the minimum value (threshold value) of the number of votes for determining to display the crime prevention environment information on the map is stored in the ROM 305 of the server 30, and the item is added to the crime prevention map only when the number of votes exceeds the minimum value. May be displayed.
This minimum value may be input by the administrator via the input / output interface 306, or based on a calculation result calculated based on information such as the number of votes up to a certain period before and the number of crimes actually occurred. It may be automatically updated.
In other words, the server 30 functions as artificial intelligence, can automatically change the judgment criteria of the crime prevention environment information, and can further improve the crime prevention environment information displayed on the crime prevention map.

Also, the total number of votes in a certain area may be calculated, and a numerical value inversely proportional to the total number of votes may be displayed on the crime prevention map as a parameter α representing “attitude of belonging”.
That is, it is considered that the more the total number of votes is and the lower the parameter α indicating “attribution consciousness” is, the higher the consciousness to crime prevention is, and the less likely the crime occurs.
Also, the parameter α may be added to or multiplied by the number of votes at each point and displayed as the degree of risk.
That is, an area with a small total number of votes and a low “attribution consciousness” has a low awareness of crime prevention and is likely to be targeted, and has an effect of encouraging vigilance by increasing and displaying the total number of votes cast.

  Note that the data server 30 may acquire not only information transmitted from the mobile terminal 10 but also peripheral information such as weather, sunrise, and sunset time, and reflect the contents in the crime prevention map.

  The operation of the present embodiment configured as described above will be described with reference to FIGS.

The crime prevention system according to the present embodiment divides a region to form a plurality of crime prevention groups, and a person who lives in the region and carries the mobile terminal 10 can register with the crime prevention group. .
The portable terminal 10 is preinstalled with a crime prevention application that can function in the crime prevention system according to the present embodiment. When the mobile terminal 10 wishes to vote for crime prevention, the mobile phone 10 displays a voting screen periodically by launching a security application or regardless of the intention of the mobile phone (S1). The portable terminal 10 receives a GPS signal and acquires current position information when a security application is launched. Thereafter, a map centering on the current position is displayed on the screen, and the user is prompted to input a place related to crime prevention information (S2).

The carrier of the mobile terminal 10 inputs information by selecting (inverting) a selection button of an item that matches his / her subjectivity with respect to the item displayed on the voting screen.
Also, in the case of information related to a location different from the current position, the position information related to crime prevention information to be input is input by moving the cursor or scrolling the map to change the center position by the operator's operation. (S3). Further, the location relating to the input information is photographed by the camera 108 and stored (S4).

  Next, in the signal processing unit 105, the portable terminal 10 generates a transmission signal from the current date and time, the attribute of the portable person, and the captured image of the camera, in addition to the vote contents and position information input by the portable person (S5). The generated data signal is transmitted (S6).

The data server 30 of the data center 20 receives the signal transmitted from the mobile terminal 10 (S7).
Based on the received data, the voting results are tabulated for each point, each time zone, and each item (S8).
Further, the total number of votes in the area collecting the crime prevention information is totaled (S9).
Then, the value of the parameter α is calculated on the assumption that the parameter α representing the level of belonging to the area by the residents of the area is inversely proportional to the total number of votes (S10).

Next, the data server 30 creates a crime prevention map in which the map information of the area, the location information of points related to crime prevention information, the total number of votes, and the value of the parameter α are displayed numerically (S11).
And the data of the produced crime prevention map are transmitted to the information terminal 40 or the portable terminal 10 (S12).
The time interval for creating the security map can be set arbitrarily. If necessary, it is possible to create and provide a real-time security map by updating and transmitting the security map information in a short time.
In addition, this crime prevention map displays the total number of votes and the value of parameter α as a numerical value, etc., so the crime prevention environment state can be clearly recognized at a glance and the crime prevention environment state can be displayed advantageously. Can be created and provided.

The mobile terminal 10 and the information terminal 40 can receive the crime prevention map information and display the crime prevention map received by the operation of the registered residents or the like (S13, S14).
This crime prevention map displays the crime prevention environment state numerically, etc., and displays the crime prevention environment state accurately. This crime prevention map is disclosed to the local residents, and the crime prevention map is efficiently managed by the crime prevention patrol. Can be useful.

In this embodiment, step S7 corresponds to the receiving step in claim 1 and the communication procedure in claim 3. The communication means in claim 2 is realized by the data server 30 that executes step S7.
Step S8 corresponds to the first tabulation step in claim 1 and the first tabulation procedure in claim 3. The data server 30 executing step S8 implements the first tabulation unit in claim 2. ing.
Step S9 corresponds to the second tabulation step in claim 1 and the second tabulation procedure in claim 3. The data server 30 executing step S9 implements the second tabulation unit in claim 2. ing.
Step S11 corresponds to the information display map creation step in claim 1 and the crime prevention map creation procedure in claim 2, and the security map creation means in claim 2 is realized by the data server 30 executing step S11. .

Note that the icon color in FIG. 5A may be changed or the background color or character color of the pop-up window may be changed depending on the value of the parameter α representing the sense of belonging.
For example, it is displayed that the degree of danger increases in the order of blue, yellow, and red. Alternatively, it is displayed that the degree of danger increases as the color becomes darker.
The parameter value may be added to or multiplied by the number of votes for each item.
In this way, by reflecting the value of the parameter α in the security map, it is possible to inform the user of the security map that the degree of risk is not low even when the number of votes is small because the interest in security is low.

According to such a crime prevention map creation method shown in the present embodiment, it is possible to easily perform a vote regarding crime prevention from a portable terminal that is always carried by a local resident or the like.
In addition, the voting results related to crime prevention are aggregated by the data server, and at the same time, parameters representing the sense of belonging to the area such as local residents are calculated from the total number of votes, and a crime prevention map can be created and provided at short time intervals. That is, by updating the crime prevention information at a short time interval reflecting the contents of voting by the local residents, it is possible to create and provide a real-time crime prevention map that matches the senses and consciousness of the local residents. Moreover, it is possible to create and provide a crime prevention map that can advantageously display the crime prevention environment state by displaying the crime prevention environment state with a numerical value or the like.
