Description

  The present invention monitors a gaming machine (including a cell) such as a pachinko machine, a revolving game machine (pachislot machine), and its players in a game hall by installing a network camera and encrypts the captured moving image. This is related to a monitoring, diagnosis, analysis, and recognition system that prevents wiretapping, tampering, and impersonation of data.

Conventionally, a network-compatible surveillance camera is connected to the monitor device via the network, and the remote camera has been configured to monitor the video shot on the monitor device side or to control the pan / tilt operation of the surveillance camera. There is a system.
FIG. 7 is a configuration diagram of a conventional surveillance camera. The surveillance camera unit 100 is connected to a network 103 via a router 102 that can determine and pass only the necessary packets by determining an optimum route.
The surveillance camera unit 100 drives the pulse motor and is attached to the camera body 111 according to the command value of the control unit 105 that outputs the rotation angle of the camera as a counter value in response to a command from the monitoring unit 104 connected to the network 103. The field of view 113 is moved by turning around 112 to cover a wide field of view range 114.

FIG. 8 is a diagram showing a display image of the monitor display unit. In this case, the captured image is displayed as a line with a black circle indicating the pan rotation range (from the CCW end to the CW end) of the camera. Is displayed with Δ cursors C1 to C2 representing the position of the software limit switch. In addition, the limit position values (20 ° to 300 ° in the figure) are displayed in the boxes D1 and D2. These limit switch position and box position can also be used to set the rotation range. Similarly, a tilt operation is displayed on the left side of the screen.
Further, as shown in FIG. 9, according to the angle of view of the camera, for example, when the angle of view is 60 degrees, a landscape corresponding to the full limit switch range (turning range) is displayed with six images and designated. The limit position can also be determined by converting the positions of the images (for example, image A and image B) into numerical values.
FIG. 10 is for creating a camera command from the screen. When a composite screen in which the entire monitoring range is covered is created on the display screen and an area A indicated by hatching is clicked and instructed, an image at this position is displayed. The camera can be moved to a position where the camera is photographed (see Patent Document 1).

  On the other hand, as a remote monitoring system in a game arcade such as a pachinko or pachislot machine, there is a “game machine monitoring system” disclosed in Patent Document 2. FIG. 11 is a system connection diagram of a conventional gaming machine monitoring system. In general, the pachinko hall is divided into a plurality of sections (commonly called “islands”) in which pachinko and pachislot machines are continuously arranged, One island center 300 is provided for each island, and all terminal monitors 301 on the island are connected as shown in FIG. Usually, pachinko machines are arranged in one row (in the case of an island facing the wall) or two rows on the island. Communication between the island center 300 and each terminal monitor 301 is performed by half-duplex binary synchronous communication, and all the island centers 300 are connected to the hall server 310 via the bus line 313 and are connected by packet communication or the like. Communication is taking place. The island center 300 always collects information on the terminal monitor 301 in the island, and when an abnormality occurs, it immediately transmits the abnormality information to the hall server (hall computer) 310, and the game machine program is illegally operated. By monitoring the program execution status and data, it is possible to detect illegal acts such as rewriting or irradiating an abnormal radio wave to the pachinko machine and distorting the operation of the gaming machine.

As for encryption of various types of communication conventionally performed in a game hall, for example, “a data communication method for a game facility” disclosed in Patent Document 3 can be cited.
FIG. 12 is a block diagram of a conventional game facility data communication method. The hall computer 400 mainly receives the data of each device transmitted via the communication line 408. In order to conceal data transmitted / received to / from each device, a public key pk1 for encrypting data transmitted from each device to the hall computer 400 by a predetermined method and a secret key sk1 for decrypting the original data are provided. It is stored in the storage area. The public keys of the other devices are also stored in the storage area of the hall computer 400, and the public keys pk2 to pk6 of each device are used for transmission from the hall computer 400 to each device. Similarly, in addition to the public key pk2 and the private key sk2, the free gift management POS 403 automatically sells the public key pk3 of the ball counter 404 that encrypts the transmission data to the ball counter 404, the public key pk4 of the ball lending machine 405, and automatic sales. The public key pk5 of the machine 406 and the public key pk6 of the gaming machine 407 are stored.
In such a configuration, for example, when data is transmitted from the ball counter 404 to the hall computer 400, the ball counter 404 encrypts it using the stored public key pk1 of the hall computer 400 and receives it. The hole computer 400 can decrypt using its own secret key sk1. Similarly, when transmitting from the ball lending machine 405, the vending machine 406, and the gaming machine 407 to the hall computer 400, each device encrypts using the stored public key pk1 of the hall computer 400, and the hall computer 400 receives it. The transmitted data from each device can be decrypted with the self-secret key sk1.

However, in the case of the monitoring camera disclosed in Patent Document 1 in the above-described conventional example, a basic image monitoring function is built-in, but a function for encrypting a moving image in real time and transmitting and storing it, TCP, UDP / IP However, since it does not have a local and wide area network transmission function of captured moving images by HTTP, FTP, etc., there is a problem that it is impossible to cope with network and coexist with encryption.
In addition, in the case of Patent Document 2, although it is a network monitoring system in which a CPU board is built in a gaming machine and has a terminal function, it is a technique of indirectly detecting a player's unauthorized operation or the like from a change in data. However, there is a problem that discovery probability, certainty, and responsiveness are low compared with a direct method of visually capturing from a captured image.
In the case of Patent Document 3, communication data that conveys the operating status from a gaming machine such as a ball lending machine or a pachinko machine in the gaming hall to the hall computer is encrypted to prevent eavesdropping and tampering. If the public key is used as is for the encryption key using the key method encryption with the private key, it is difficult to prevent falsification of the data when creating the key, and the enormous amount of data such as transmission of moving image data is complicated. Encrypting with a simple public key reduces the processing speed and loses real-time performance. Especially when trying to build a monitoring system that concentrates and monitors moving images from several hundred to 10000 cameras including one hall unit or affiliated halls, the processing speed is slow and the line traffic is fatal. It becomes a problem.

Focusing on the processing speed, the SSL (Secure Socket Layer) method is frequently used in Web transmission-type electronic commerce, billing / financial services, and the like. The SSL method is also a public key method, but a common key is generated and exchanged between the transmission side and the reception side, and the transmission side is encrypted and transmitted with a common key simplified from the public key, and the reception side is also common. The processing speed is improved by decrypting with a key.
However, this SSL method has also been told of the occurrence of attacks in the United States, and 100% safety cannot be guaranteed. This is because since the SSL is decrypted by the browser on the receiving side, the decrypted plaintext raw data is accumulated in a browser cache or the like and can be duplicated to enable the reproduction of the common key. As described above, there are various problems with encryption of transmission data.

  Therefore, the present invention remotely monitors a player's unauthorized operation and health status in a game hall, moving images such as facial expressions and hand movements captured by the camera by installing a network camera for each gaming machine etc. The monitoring video data can be monitored in real time, and the common key can be exchanged for each file or packet, as in the IPsec method that dynamically changes the common key. Introduced a new real-time encryption method using a public key and a common key that can be exchanged at a frequency of 1000 times or more per second and the cipher itself automatically changes the common key, and added a cache file deletion function The SSL clearing hole is filled by strengthening the plaintext decryption function decrypted by the above, and the encrypted data such as gaming machines is added to the confidentiality, safety, authenticity and denial Constructing an encryption system that can guarantee the prevention function, and immediately detecting and removing illegal operations by the player, wiretapping / falsification / spoofing of data, etc. It is an object of the present invention to provide a gaming machine and a player monitoring / diagnosis / analysis / recognition system that can provide a game environment.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a configuration diagram of a gaming machine and a player monitoring / diagnosis / analysis / authentication system according to an embodiment of the present invention.

In FIG. 1, 1 is a network camera, 1a is a camera installed on the gaming machine 2 and captures a moving image of the player's face and hands, and 1b is a camera installed on the ceiling to monitor a wide area. The network camera 1 (hereinafter, also simply referred to as camera 1) can perform voice transfer together with a moving image, and can perform real-time encryption that encrypts and transfers a captured moving image in real time. In addition, a plurality of cameras 1 necessary for centralized monitoring or distributed monitoring on an administrator monitor (manager terminal: not shown) are blocked as a unit, and the blocked images are divided and displayed on one screen of the monitor. Multi-camera function, moving object recognition / moving object deletion function for monitoring data extraction / analysis, software cloud that can select / switch display of camera operations such as pan / tilt / zoom of camera 1 specified from multiple monitors Built-in network protocol such as TCP, UDP / IP, HTTP, FTP, etc., which constitutes a stand-by function, a moving image thumbnail function, and a network transmission function of captured moving image data. It is also possible to provide an intelligent terminal function having the above processing and transmission / reception function.
As a form of monitoring on the administrator side, a system for centralized monitoring using an administrator terminal (not shown) provided in the hall application server 7 or the server group 12, or a plurality of administrator terminals communicating via the Internet 9 or the like By connecting to the server group 12 and the like via a network and configuring a linkage system, it is possible to make a system that performs distributed monitoring that can be monitored from an administrator's monitor provided at any point inside or outside the hall.

2 is a gaming machine such as a pachinko or pachislot machine, and 3 is an island in which the gaming machines 2 are juxtaposed in two opposing rows. Reference numeral 4 denotes an island BOX computer (island moving image server: composed of a commercially available personal computer or an industrial personal computer). The camera 1 is a wireless LAN, wireless USB, PLC (Power Line Communication), LAN cable indicated by a dotted line. And so on by the island network 5. The island BOX computer 4 collects monitoring moving images, reduces the amount of moving image data transmitted from each camera by an image processing function, extracts image data using a moving object recognition / erasing function, JPEG In consideration of compression processing such as MPEG, cyclic transmission processing, and the like, a moving image encrypted and transmitted by each camera 1 by real-time encryption (by an encryption system of the present invention described later) for security. Data is transferred in response to a request from the hall application server (hereinafter abbreviated as HAS) 7.
In addition, the island BOX computer 4 is connected by the main control unit 13 that controls the game of the gaming machine 2 and the work 5, and collects gaming machine operation data. Based on a predetermined program, it monitors and manages whether it is operating based on laws and regulations.

Reference numeral 6 denotes a hole network such as a LAN or PLC that connects the island BOX computer 4 and the HAS 7. The network is constituted by the Internet 9, and a broadband broadband network including the island network 5 is constituted.
A hall application server (HAS) 7 manages the encrypted moving image data input from the island BOX computer 4 and the operating status data of each gaming machine and peripheral devices, and remotely controls gaming machines in the entire gaming hall 8. Deploy monitoring / diagnosis and management services.
The HAS 7 is connected to a third party management center 10 such as a CA (Certificate Authority) via a wide area network such as the Internet 9 and is actually an administrator who is actually engaged in the monitoring and diagnosis of moving image data. -Configure the authentication system by acquiring and registering public keys for each access right person. As a result, the public key of which (with which camera) the public key is authenticated is authenticated, so that the moving image data by the camera 1 is limited to the administrator / access rights holder limited to protect the player's portrait rights. The access right to the moving image file is strictly limited so that the encrypted data of the moving image can be decrypted by the public key authentication function.
Further, the HAS 7 is configured to be able to control and operate the same data by connecting to a plurality of affiliated halls 11 and performing various business tie-ups and horizontally deploying them. As a result, a regional / centralized distributed monitoring / management system including camera information of each gaming machine in the affiliated hall 11 can be constructed.

Thus, in the system according to the present invention, when configuring a centralized / distributed monitoring system including the final affiliated hall 11, the number of network cameras 1 that are actually installed is only the camera 1a provided in each gaming machine. However, [(island game machine mounting camera × number of islands = number of cameras in the entire hole) × number of series holes], the total number of cameras is 5000 to 10,000 or more. The objective of this system is to construct a ubiquitous and inexpensive system for monitoring and diagnosis by these cameras. In this case, all cameras are assigned and managed with a local IP address, and the number of global IP addresses is reduced by performing an IP address conversion operation by V6-V4 tunneling between the game hall 8 and the Internet (Web network) 9. You can also
In this embodiment, security is enhanced by distributing cryptographic servers and databases for efficiently processing a huge amount of data in the case of centralized / distributed monitoring. In other words, contract with the deposit system of the image storage type server, and the HAS7 and ASP service cooperate to distribute the moving image monitoring / diagnosis server business. The server group 12 including various possible systems and the HAS 7 are connected.
Communication between the affiliated hall 11, the server group 12, and the third party management center 10 via the HAS 7 and the Internet 9 uses VPN (Virtual Private Network) and maintains security by the latest encryption system. Form.

FIG. 2 is a diagram showing the procedure of the hybrid cryptosystem used in the system of the present invention.
In this encryption method, the public key 15 is complex and safe as an encryption key, but the processing time increases for image data, so encryption with the fast common key 16 is performed.
First, the public key 15 is transmitted from the administrator computer (reception / key creation side) 17 to the network camera 1 (transmission side island side). The transmission side that has received the public key 15 selects and generates the common key 16, encrypts the plaintext image 18 with the common key 16, and encrypts the common key 16 with the public key 15 that has received the common key 16. The key 16 is transmitted to the administrator computer 17. As a result, the common key 16 can be exchanged safely.
The received administrator computer 17 decrypts the public key 15 with its own private key 19 to extract the common key 16, and decrypts the ciphertext with the common key to obtain plaintext. Thus, an encryption system that guarantees safety and does not decrease the processing speed is configured.

Next, the operation will be described with reference to the flowcharts shown in FIGS.
FIG. 4 is a diagram showing an authentication procedure of the access person. When an administrator who is given access rights to the moving picture encrypted file accesses, first, the encryption common with his / her public key is used. The key is accessed (S1). The encrypted common key is decrypted with the public key and a pair of decryption keys to obtain the common key (S2). The encrypted file is decrypted with this common key, and the plaintext / image is read (or judged / determined) (S3).
Logging is performed for this access, and when and who has read which encryption file is recorded. In the case of unauthorized access due to eavesdropping, tampering, or impersonation, it is detected and the accessor cannot deny the unauthorized pursuit. Safety is guaranteed by the non-repudiation function (S4).
When the access ends, the plaintext / image is deleted in consideration of safety so as not to leave a trace of the raw data (S5).
What should be considered here is the risk of impersonating another person from the time of creation and release of the public key. Since the communication partner cannot be seen in communication via the network, there is a possibility that the third party impersonates the communication partner and sends the public key, and the ciphertext is decrypted by the third party. Therefore, in the public key cryptosystem, it is necessary to confirm whether the public key used is really the correct counterpart.

  FIG. 3 is a block diagram showing the functions of the third-party management center 10 shown in FIG. 1. As shown in FIG. 3, an organization that guarantees the validity of the public key as a public key confirmation (authentication) method. (Certification Authority: CA, etc.) is installed by a third party, and the hall supervisor 20 sends the public key to the certification authority (CA) with an identification card or hall authorization attached, and from the certification authority (CA) 21. A public key and a public key 22 signed by a certificate authority are returned as a certificate that guarantees the public key and its owner. First, the receiver transmits the public key 22 signed by the CA 21 to the sender and receives it. The sender confirms the attached receiver information and the signature of the CA 21 to perform communication. Therefore, even if a third party sends a public key, the sender can detect spoofing because the sent public key does not have a certificate, and secure communication can be performed.

FIG. 5 is a diagram showing a procedure for giving access authority to a higher-level public key issuer.
When granting access authority to a public key issuer (for example, Secure Electronic Communication Technology Association as a third-party certification organization: conceived as a safeguarding association, etc.) It can also be limited to what file (when it is a game machine camera or ceiling camera).
First, the common key of the specific encrypted file is made common to all access right holders (S10). The encryption key (common key) is changed in units of files (S11). An access right for each encryption file is given to the public key owner (S12). It is authenticated when and who has read which encrypted file (S13).
This makes it possible to protect the system with authenticity and denial prevention functions.

In addition, similarly to Patent Document 3, etc., gaming machines, various gaming machine cells (management information collection terminal, surveillance camera, prize management machine, game ball / metal counting machine, lending machine or prepaid card management machine) Etc.) is input / decrypted to the island BOX computer 4 via the island network 5 as encrypted data, and the hall management data such as hit / probability data, operation rate, game balls / metal sales, etc. In addition, management of history data and analysis data, etc., and a comprehensive game hall management system using camera monitoring data including these can be easily constructed without the need for facilities such as a conventional hall computer system.
Further, as an example of expansion to the encryption and security system integrated management including the above-described denial prevention function, safety function, authentication function, etc., for example, a digital signature by a public key method is applied, and data of the island BOX computer 4 is applied. Using the collection / transfer function, the game program IC (ROM) data of the gaming machine 2 is read, and the read data is processed by the island BOX computer 4, HAS7, etc. according to the signature method using the secure hash function. And the standard output data that has been processed and held in advance by a secure hash function, and if the two outputs are not identical, the program has been illegally exchanged or tampered with If the two outputs are the same, it is determined that no unauthorized operation has been performed and it is normal and the game starts. Pre-check function, and the like by the data monitoring such as to allow it also becomes possible.

FIG. 6 is a block diagram of an encryption method based on the new real-time encryption system.
FIG. 6 is a block diagram of a new encryption system called the MRT cipher, which can change the common key 1000 times / second or more. The captured moving image data collected from the network camera 1 includes a random number generator 23, an irreversible data. After the processing of the function group 24, the key generation / shared unit 25 generates an encryption key, and the stream encryption unit 26 converts the encryption key into a real-time encryption. It is sent to “Web browser → provider → server” or the like as an encrypted content that cannot be encrypted, and sent to the designated administrator server or administrator terminal.
Since this system can change the common key more than 1000 times / second, if such an encryption system is used, the security can be enhanced extremely, and high-quality image, voice, and data can be encrypted because of its real-time characteristics. Become.
