Description

The present invention relates to a surveillance system, and more particularly, to a security camera installed in various places, a system capable of discriminating the owner or a person or an organization that can view images taken by the camera. is there.

Currently, security cameras are installed in each home and facility. Current security cameras are mainly used to monitor intruders in their homes and facilities.
On the other hand, police, public organizations, NPOs, etc. are installing security cameras to deal with crimes in public places. In this case, it is very important from the viewpoint of privacy that the photographer knows who installed the security camera and who can view it. Also, even if a security camera is installed in a public place for the purpose of voyeurism, ordinary people cannot distinguish. Therefore, it is necessary for the human being to take a picture to know who the security camera is installed, who can view it, and what purpose it is.

A new security camera operation characterized by separating the person who owns and manages the image (owner) and the person who can view the image (viewing right holder) by encrypting the image. The concept is proposed at the e-surveillance network study group of the non-profit organization organized by the inventors. As a result, the encrypted image is passed from the owner to the viewing-right holder only when both the owner and the viewing-right holder admit that it is necessary, such as when an incident occurs, and the viewing right holder decrypts the view. Will be done. As a result, no one can view the images except in an unnecessary case. This concept is proposed to promote the spread of security cameras throughout the community by reducing the risk of privacy infringement and, at the same time, reducing unnecessary mental loads that can be imparted to third parties. It is done.

In recent years, the spread of security cameras has been remarkable worldwide, but with this, concerns about privacy infringement have become stronger. In the operation of the security camera, the owner / manager / viewer of the image taken by the security camera are the same. However, in many cases, the captured images are never viewed unless an incident occurs. This stems from the fact that in many places incidents do not occur so often and the labor costs required for browsing are high. However, the fact that “photographed images can be freely viewed by system owners” has a great mental burden on the general public, which is a major obstacle to the further spread of security cameras. It has become.

Therefore, in places other than where high security is required, which must be monitored by humans at all times, that is, in most local communities on the planet, security cameras can be used by operating security cameras based on this concept. Privacy infringement and its concern can be greatly reduced without compromising the utility (deterrence of crimes, provision of stored images to crime investigation agencies when crimes occur) due to the introduction of cameras.

In an embodiment in Kiryu City, Gunma Prefecture, a PC-based security camera system owned and managed by each store owner of the store association encrypts and stores images. The only way to view the stored images is to use dedicated software installed on a PC installed at the Kiryu Police Station. Only when both the shop owner and the police approve the need, the shop owner provides images to the police, and the police browse the images for use in the investigation. Unless an incident or accident occurs, encrypted images stored at each store are automatically deleted after 30 days.

As a method of guaranteeing that the system is based on this concept, in the Kiryu City example, it is adopted to post a declaration sentence to each store that “we will be inspected by the police at any time”. As a reliable guarantee law, patents have been filed for inventions with the following characteristics. (Invention of seal seal method)
・ Use various cameras (access password, encryption key, etc.) that have been baked in a non-rewritable format and sealed with a seal that cannot be removed unless broken.
・ Seals will be sealed by public authorities. The seal will clearly indicate the sealant and the viewing rights holder.
As a result, a general passer-by can see that the image taken by the camera is stored in an encrypted state only by looking at the camera from the outside, and no one can view the image unless there is an incident. be able to.

This concept was originally created for the purpose of promoting the spread of the e-Self Security Network that we advocate as a concept related to security camera operation. eSurveillance network means that each person watches his / her personal life from the sense of responsibility as a citizen, and uses PCs, free software, and PC cameras as means. The community where many citizens watch in front of their homes is considered to acquire high crime deterrence.

Here, it should be noted that the stability and reliability of individual systems do not have to be very high from the viewpoint of crime prevention effect and criminal identification ability in the whole community. This is a point that can be used. In addition, it is characterized by the fact that it is based on the fact that each citizen is introduced voluntarily, so there is almost no financial or human burden on the government. Furthermore, because images are owned and managed in a distributed manner by individual citizens, the risk of privacy infringement is less than that of a normal system in which police and other organizations manage and own images from many cameras. I think it is small. This system has been successfully introduced in many areas including Maebashi City, Gunma Prefecture.

However, it is also true that there are many voices about the danger of privacy infringement, and it has been analyzed that this was the biggest obstacle to the explosive spread of e-Self Network.

In order to carry out this “concept of privacy protection by encryption” more reliably, “I do not conduct inspections at police stations, residents' associations, etc. “I vow to accept the conditions” is not enough. In that respect, the spread of the “new concept” has made it possible to realize a more reliable guarantee by the patent document 1 which is the previous invention. However, security cameras are often installed out of the reach of people, and therefore it was not easy for passers-by to read the stickers on the security cameras. There was a strong need to resolve this issue.

The present invention is characterized in that the security camera itself reveals its identity by electronic means positively and explicitly. The present invention makes it possible for the security camera itself to clarify its identity more positively and more explicitly. The present invention is a key concept in spreading security cameras to public spaces such as roads in general residential areas.
JP2009-44311

Security cameras are installed for the purpose of crime prevention, etc. The functions that attract attention are mainly camera functions, and there are many techniques such as motion detection. However, with the widespread use of security cameras, there has been a problem of the privacy of the subject. The subject cannot know how the captured image is used and when it was captured. In other words, the consideration for the subject is not fully paid.

It was clear from the previous installation methods for security cameras that who installed the security camera and who was viewing it. In other words, it could be easily guessed from the place where it was installed, but now it is installed in a public place, and even if it is installed in each home, the installation subject is a public institution. There is no way for the photographed person to know such information because the person who installed the camera or who can view the image is unknown. On the other hand, there are Patent Document 2 and Patent Document 3 as security camera systems in consideration of privacy. The purpose of both is to protect the privacy of residents in the elevators of apartment buildings, and it is not considered to protect the privacy of an unspecified number of people in the public place of the present invention.
JP2008-72258 Patent No. 3743403

  From such a background, the present invention solves the problem that the person photographed with the security camera does not know the information about the security camera such as the security camera owner, administrator, image viewer, and installation location. This can prevent infringement of the subject's privacy. Security cameras play an important role in ensuring the safety and security of society, but on the other hand, there are significant privacy issues, which hinder the spread of security cameras. As a result, the present invention greatly contributes to the spread of security cameras.

It is difficult to confirm whether the security camera is true even if it is written on the security camera and who has set up the security camera and who can view the image. Therefore, it is necessary to make it possible for anyone to check information about security cameras electronically and not to disguise that information. If it is camouflaged, a camouflaged security camera will be installed, and the image taken by that camera may infringe the privacy of the subject.

  For this reason, in the present invention, the basic technical solution is to check the ID information by reading information (ID information) such as the owner of the security camera using a PC or a dedicated device. However, this method simply impersonates the ID information. Therefore, it is necessary to devise a mechanism for encrypting and checking ID information.

It has an information disclosure means to inform the PC, mobile phone or other electronic device of information (ID information) about the security camera such as the security camera owner, administrator, image viewer, installation location, etc. It is a security camera system. As information disclosure means, wired communication, wireless communication, two-dimensional barcode, display of images and character strings, provision of voice, and encryption of them are used.
In addition to cameras installed at fixed points, cameras installed in high density on the ceiling of public transportation such as trains, buses, passenger planes, cameras built into things carried around with a bag, belt, etc., mounted on automobiles It is also suitable to apply the present invention to security cameras including other cameras.

The security camera holds information (ID information) about the security camera. This information may be encrypted. This ID information is obtained from a security camera on a PC, etc., and various information of the security camera is obtained by acquiring various information (camera information) of the security camera from the ID information by a dedicated processing method. Also, by specifying various information about the security camera on the outside of the security camera, it is possible to easily understand the various information about the security camera, and the authenticity of the information obtained from the ID information of the security camera. It can also be confirmed by comparing with various information. This allows the photographer to know various information about the security camera.

ID information is acquired from a security camera, and instead of acquiring various information about the security camera using a dedicated processing method, the ID information is transmitted to a server designated in advance, and the server shows various information about the security camera. By this, the photographed person can know various information of the security camera.

The method of obtaining ID information from a security camera and obtaining various information of the security camera based on it is simple and can be realized at low cost, but there are also problems. For example, if a security camera is installed at a certain location, a malicious person replaces the real security camera with a camouflaged security camera, embeds the ID information of the real security camera in the camouflaged security camera, and is camouflaged. The security camera returns the ID information of the real security camera in response to the request for ID information. As a result, even if the ID information is encrypted, the camouflaged security camera can behave like a real security camera. In this case, various information of the security camera will be deceived.

One way to solve this problem is to prevent ID information sent from security cameras from being constant, that is, to change it. Specifically, the transmitted ID information is encrypted with an encryption key that changes with time. The received ID information changes with time, but various information of the security camera can be acquired by a dedicated processing method. With this method, even if ID information is obtained from a real security camera and embedded in a camouflaged security camera, it is not clear how to change the ID information over time, so the correct ID Security cameras camouflaged with information cannot be sent.

When obtaining information related to security cameras by decrypting ID information on a PC, the mechanism of the decryption processing may be clarified by a third party by analyzing the processing method that operates on the PC. There is. For this reason, the ID information transmitted from the security camera is sent to a predetermined server without decryption by the third party's PC, and this server performs processing such as decryption, and obtains information on the security camera obtained. Reply to PC. In this way, information about security cameras can be obtained on a PC. With this method, the risk of analyzing the processing method related to ID information is reduced.

Another means of preventing the ID information sent from the security camera from being abused is to send appropriate data from the PC to the security camera, and the security camera performs a dedicated process from the data and the ID information, and the result is security. It is a method to obtain information about security cameras by using appropriate data and reply data as a reply from the camera. Specifically, appropriate data (A) is sent to the security camera from a PC, etc., and a response (B) from the security camera is received. (B) includes information on security cameras. A PC or the like performs a dedicated process to determine whether (B) is obtained from (A), and if so, obtains information about the security camera from (B). Also, instead of performing dedicated processing on a PC, the information of (A) and (B) is transmitted from a PC, etc., to a specified server, and dedicated processing is performed on the server. It is determined whether or not B) is obtained. If so, information on the security camera is acquired from (B), and the result is returned to a PC or the like. As a result, the photographed person can obtain various information about the security camera.

The methods shown so far have made it possible to obtain various information about the security camera and prevent impersonation by using something other than a security camera such as a PC or server. As a method of acquiring information about security cameras using only security cameras and preventing camouflage, if a camouflaged security camera is installed in a location where multiple cameras are installed, the real security camera is camouflaged. By detecting the security camera, it is possible to prevent the security camera and information about the security camera from being camouflaged. Specifically, a plurality of security cameras communicate with each other and confirm that the security cameras that should have been installed are in operation. Make it impossible to install. In addition, by disseminating the number of security cameras installed regularly around the security camera, if a camouflaged security camera is installed, the number of cameras to be photographed is known. From the difference in the number of cameras, it can be detected that there is a camouflaged security camera.

For security camera systems installed at high density on the ceiling of public transportation such as trains, buses, and passenger planes, information on security cameras such as security camera owners and managers, image viewers, and installation locations It is possible to give the user a sense of security by providing information disclosure means to inform PCs, mobile phones or other electronic devices. In particular, with encryption, the administrator is clearly separated from the operating company of the relevant transportation system, and the viewing rights holder is clearly separated from the police, and unless there is an incident, the images are not automatically viewed by anyone and are automatically deleted after a certain period of time. This system can reduce the psychological resistance of users and facilitate the introduction of the system. Such a system makes it possible to ensure the evidence of crimes in public transport. In addition, such a system is expected to make a significant contribution to the reduction of atonement in molestation. This system makes it possible to reduce anxiety about crimes and anxiety about crimes while reducing discomfort and stress related to privacy violations by security cameras.

Also, for security reasons, it is considered meaningful to be able to monitor passenger seats as needed in passenger aircraft. For example, such a monitor may be performed on the ground by a police officer with special qualifications.

You can cleanly remove the part of the security camera that was regarded as a necessary evil of "risk of privacy infringement". With the increasing threat of terrorism, security cameras are exploding in popularity as a necessary evil.

If the risk of infringement of privacy is reduced, there will be no obstacle to the spread of security cameras, and many places will be the surveillance range of security cameras. Criminals can no longer escape out of surveillance by security cameras, which has a tremendous effect on arrest of criminals, resulting in a reduction in crime.

With the system of the present invention, it becomes possible for each household to monitor not only the house but also public places such as the road in front of the house, thereby improving the security of each house. In addition, because public places can be monitored by security cameras installed by each household, police and government can increase the safety and security of the town without financial burden. The present invention is a key idea for e-security camera (= security camera system with privacy protection function by encryption).

1 is characterized by having information disclosure means for informing a PC, a mobile phone or other electronic devices of information about the security camera such as the security camera owner, manager, image viewer, installation location, etc. An illustration of the security camera system is shown. In this example, the camera is a stand-alone type, and the captured image is encrypted and recorded on the memory card. The oldest image is overwritten sequentially, and the latest image for about one week is always saved. It is supposed to be used for the purpose of thorough privacy protection by separating the owner of the camera (image) and the viewing rights holder of the image.
Image storage may be performed at regular intervals, for example, about two images per second, or may be performed when motion is detected to save storage capacity. Furthermore, it may be linked to an infrared sensor. Also, if it is intended to direct the face towards the camera to passers-by, such as when motion is detected, sound (beep, greeting such as "Hello", etc.), it is also effective to issue.

In this example, the disclosure information is as follows.
-Name of the camera owner-Name of the right to view the recorded image-Camera installation location, shooting range-Certification body that guarantees the reliability of this disclosure information In this example, the camera is a stand-alone type, such as the Internet And are not connected. It only communicates with nearby electronic devices using short-range wireless communication methods such as Bluetooth. Cameras and other electronic devices owned by passers-by who pass near the camera automatically communicate with the short-range wireless communication method such as Bluetooth, and the disclosure information of the camera is sent to the passer-by's electronic devices. . Each passerby sets up a portable electronic device in advance and decides whether or not to perform that kind of communication.

Cameras can also ask for disclosure of the identity of the inquirer when providing information. At that time, it may be possible to record the information and history of the inquirer's identity and disclosure contents in a dedicated file on the memory. Since this record requires a small capacity, it can be stored for a long period of time, such as several years.

In addition, when the camera body is installed in a form that is difficult to find, it is possible to make ambiguous information about the “camera installation location and shooting range” in the disclosed information. Obscure the position of the camera body and the field of view may be effective in enhancing crime prevention effects. Passers can obtain more detailed information by communicating with the certification body. The following information is assumed as more detailed information.

-Information about the security camera network managed by the same owner, including the camera.
-Operation rules for the camera (information such as when an image is passed from the owner to the viewing owner)
・ Name / address / contact of the camera owner / Name / address / contact of the right to view the recorded image ・ Details of the camera (position, field of view, camera specifications)
・ Cameras certified by the certification body name, address and contact certification body that guarantees the reliability of the disclosed information may be sealed with a seal that breaks when opened. In particular, the following prior inventions
When sealed with a seal seal based on JP2009-44311, a synergistic effect with the present invention is obtained.

In the method of obtaining ID information from a security camera and obtaining various information of the security camera based on the ID information, even if the ID information is encrypted, this ID information is used and the ID of the real security camera is used for the camouflaged security camera. By embedding information and having the camouflaged security camera return the ID information of the real security camera in response to a request for ID information, the camouflaged security camera can behave like a real security camera. One way to prevent this is to change the ID encryption key over time. Figure 2 shows this.
The security camera in FIG. 2 sends the data obtained by encrypting the ID information of the security camera using a secret encryption key and a time-dependent encryption key to the PC. This transmitted data may be combined with an encryption key that changes over time. The PC that receives the data can obtain ID information by decrypting it with the encryption key that changes over time and the secret encryption key. If the transmission data includes an encryption key that changes over time, the PC extracts the encryption key that changes over time from the transmission data and decrypts it using the encryption key and the secret encryption key. ID information can be obtained.

As shown in Fig. 3, a security function is attached to the security camera, and data is sent from the PC to the security camera as shown in Fig. 3. The security camera returns the data calculated from the data to the PC as shown in 2 of FIG. The calculations performed by this security camera may vary from one security camera to another. The PC that has received the data 2 in FIG. 3 sends both the data 1 in FIG. 3 and the data 2 in FIG. 3 to the server. This corresponds to 3 in Fig. 3. The server determines whether the combination of the two data 1 in FIG. 3 and 2 in FIG. 3 is correct. If it is correct, the server sends information such as the camera owner, installation location, and image viewers to the PC. This corresponds to 4 in Fig. 3. The following is suitable as the disclosure content.

・ Photographer (owner / manager), viewable person, sealer / place / field of view / image storage period It is also possible to record the inquirer in the record. It may be possible to limit the contents of disclosure depending on the qualifications and identity of the other party.

In this embodiment, the reply data from the security camera can be changed by changing the data transmitted in 1 of FIG. As a result, those who try to disguise a security camera need to guess what kind of reply data can be obtained from the data, but this is extremely difficult.

As shown in FIG. 4, the PC receives the discrimination software from the server as shown in 1 of FIG. 4, and the PC receives the data transmitted from the security camera as shown in 2 of FIG. There is also a method to obtain information such as camera owner, administrator, and image viewer.

As shown in Fig. 5, the security camera is connected to the Internet, the URL of the security camera is disclosed on the surface of the security camera, etc., and the URL is connected via the Internet as shown in Fig. 5 Then, you can access the security camera and get information about the security camera owner, administrator, and image viewer as shown in 2 in Fig. 5. At this time, the URL is the domain name of the organization that manages the security camera, so that camouflaging can be prevented.

The URL used in FIG. 5 can be a URL guaranteed by a certificate authority using an electronic certificate such as http.

If security cameras camouflaged for the purpose of voyeurism are installed, privacy problems will occur. Figure 6 shows a security camera system that can communicate with each other. By communicating with each other, each security camera grasps the number of security cameras installed in the surroundings, and the situation is communicated to the surroundings of the security camera using a display. In Figure 6, four security cameras are operating in the park. Communication between security cameras is performed by encryption so that camouflaged security cameras cannot communicate. This allows the photographer to know the number of security cameras installed at that location. Various encryption methods such as shared key encryption and public key encryption are conceivable, and the strength can be increased by lengthening the key for encryption. In addition, by installing a display at each security camera or security camera installation location and displaying the number of surrounding cameras and camera positions obtained as a result of mutual communication between the security cameras, information about the security camera can be given to the subject. provide.

When there is a camouflaged security camera as shown in FIG. 7, when viewed from the subject, there are five security cameras set around, but the false security camera in FIG. 7 has four security cameras in FIG. Cannot communicate. Therefore, the number of surrounding security cameras provided to the subject by the four security cameras is four, and this information is displayed on a display or the like. On the other hand, the number of security cameras that the subject can find is five, and the subject can know that there are fake security cameras.

The methods shown in Fig. 6 and Fig. 7 can detect and prevent camouflaged security cameras by mutual communication between the security cameras, but replace all security cameras in Fig. 6 with camouflaged security cameras. If this happens, the subject may not be able to detect the camouflaged security camera. As a countermeasure, when the security camera can communicate with the server via the Internet as shown in FIG. 8, the activated security camera notifies the server of the information of the security camera itself. The security camera subject can access the server and check the number of security cameras in the location where the subject is located, and if a camouflaged security camera is installed, it can detect it. it can. In FIG. 8, four security cameras communicate with each other, and information on each of the four security cameras is transmitted to a predetermined server. The subject can access the server and send information about the location of the security camera operating at that location. The subject can detect the presence of the camouflaged security camera by comparing the information of the security camera that can be confirmed at the location and the security camera obtained from the server.

In the above-described method, information on the security camera is transmitted to the server, and the photographed person browses the information, so that the camouflaged security camera can be detected. However, a camouflaged security camera can be installed by operating a camouflaged security camera that is hidden from the subject while the true security camera is still in operation. As countermeasures against this, the information sent from the security camera to the server is also sent along with the video captured by the security camera, and the photographed person accesses the server, browses the video of each security camera, and what the security camera shoots The photographer confirms whether the camera is camouflaged, and can detect the presence of a camouflaged camera by comparing the image assumed from the installation location of the security camera with the image of the security camera provided by the server. it can.

It is possible to detect a camouflaged security camera with the method described above that sends information about the security camera and the video being shot to the server, but you can view the video from the security camera by accessing the server. Is possible. However, this is contrary to the prevention of privacy infringement by the security camera, which is the object of the present invention, and the video of the security camera can be seen by anyone other than the subject. Therefore, after performing image processing such as mosaic to the extent that you can see where the security camera video is being shot, the security camera sends the video to the server, so privacy by viewing the security camera video Can be prevented.

The method shown in FIG. 9 is a method for the subject to check where the security camera is shooting. First, the person to be photographed accesses the security camera and requests an access destination for confirming the image of the security camera. This corresponds to 1 in Fig. 9. Next, the security camera sends the video shot at that time to the server. This corresponds to 2 in Fig. 9. Next, after receiving this video, the server sends to the security camera an access destination for the subject to confirm the video. This corresponds to 3 in Fig. 9. The access destination at this time is assumed to be composed of a predetermined character string and a random character string so as not to be camouflaged. For example, http://www.e-jikei.org/camera/parkA/39ijflaskjlfj39434/, where http://www.e-jikei.org/ is a predetermined character string and camera The part of / parkA / 39ijflaskjlfj39434 / is a random character string. Next, the security camera sends the access destination received from the server to the subject. This corresponds to 4 in Fig. 9. Next, the person to be photographed accesses the access destination transmitted in 4 of FIG. This corresponds to 5 in Fig. 9. Next, the server sends the video that the subject has accessed to the subject. This corresponds to 6 in Fig. 9.

In order to install a security camera camouflaged for the purpose of voyeurism, etc., when attempting to camouflage the access destination, to camouflage access to http://www.e-jikei.org/ It is necessary to disguise the IP address of www.e-jikei.org in the Domain Name Service, but this is quite difficult considering the mechanism of the Domain Name Service. A random character string can be generated so that it is difficult to guess. Therefore, it is very difficult to impersonate this access destination. Also, according to 2 in FIG. 9, the server displays the video transmitted from the security camera when the photographed person accesses the access destination. As shown in 5 and 6 in FIG. 9, the subject can access the access destination, check the video, and check the video shot by the security camera.

Encrypt communication between server and security camera, communication between security cameras, communication between photographed person and server, communication between photographed person and security camera in Figures 2, 3, 4, 5, 6, 7, 8, and 9. This prevents wiretapping of communication data.

The present invention is suitable as a surveillance camera system in a residential area.
