Description

A broadcasting device capable of converting long-distance super-directional ultrasonic warning broadcasting, a security surveillance camera integrated security system for setting warning broadcasting targets, and a crime prevention/disaster prevention technology method and crime prevention surveillance through a multi-spontaneous polarization sensor applied to the surveillance camera and broadcasting device Directional broadcasting device and crime prevention surveillance camera and automatic control through camera and short-range multi-spontaneous polarization sensor Multi-spontaneous polarization sensor and smart building lighting access control automatic control }

This technology is related to security CCTV monitoring cameras, broadcasting devices, automatic control of smart buildings, access control, and lighting that automatically control moving or stationary bodies through multi-spontaneous polarization sensors.

Currently, as a human body sensor, a pyroelectric infrared (PIR) sensor is widely used.

Pyroelectric Infrared (PIR) is a principle that detects the human body by using the principle that the spontaneous polarization is maintained normally, and when infrared rays are absorbed from the human body, the temperature rises and the intensity of the spontaneous polarization is reduced. .

However, even if infrared rays are absorbed, after a certain period of time, the spontaneous polarization state reaches equilibrium again, so that the human body cannot be detected.

In order to detect a still human body in order to solve the above problems, shutter-type chopping, motor vibration, etc. were used to give the same effect as the human body moving.

However, mechanical contacts and mechanical motions have a higher failure rate and lower energy efficiency than electronic contacts.

A surveillance camera system for security is usually a combination of a wide-area surveillance camera that monitors a wide area through a fixed surveillance camera or fisheye camera and a centralized surveillance camera for intensive surveillance of an event area with a rotating motor-integrated dome camera or a pan-tilt combination box camera. to form a security system.

The present invention is a crime prevention system combined with a super-directional broadcasting system capable of warning broadcasting only for a centralized surveillance area together with centralized surveillance of control personnel or event centralized monitoring through an intelligent surveillance system in an integrated crime prevention center.

In general, security surveillance camera systems consist of 20-40W omni-directional speakers (a combination of 4 low-directional speakers with a directivity angle of 90 degrees or a combination of 3 low-directional speakers with a directivity angle of 120 degrees) to form a 360-degree omni-directional speaker. Since it broadcasts through a non-directional speaker, the audible range is limited, and if the power amplifier output of 40W or more is applied to increase the audible range, noise complaints will occur.

An object of the present invention is to solve the problems of non-directional (or low-directional) speakers and to effectively enable super-directional warning broadcasting over long distances.

As a differentiated feature of the present invention, it is characterized by system interworking with a centralized surveillance camera for the purpose of super-directional broadcasting at the shooting point of a centralized surveillance camera, not a general super-directional speaker.

That is, a differentiated feature is that optimal super-directional broadcasting is possible according to the flexible change of the distance between the broadcasting device and the broadcasting target point.

The present invention uses ultrasonic waves to implement the differentiated features. Sound wave conversion technology that improves conversion efficiency and clarity when ultrasonic frequencies are converted to audible frequencies at broadcast target points, and the broadcast target points and target points of a focused surveillance camera As a technology that matches the target distance, it applies a very precise state-of-the-art technology that changes the ultrasonic frequency and output according to the change in the target distance.

The test and performance certification test method of this technology is to install a microphone at a point that matches the center focal length of the centralized surveillance camera shooting area, and the same focal length as the measured sound pressure value P1 or the same microphone at a point outside the shooting range of the surveillance camera Test and performance certification through P1/P2 (dB) for the sound pressure value P2 measured by setting and clarity (%) over the target setting value measured at the center focal distance of the centralized surveillance camera shooting area.

Comparative evaluation is performed by performing the same test as above through non-directional speakers of 20W, 40W, and 40W or more.

The network of is composed of a Hybrid-QUANTUM CHannel to which QRNG (Quantum Random Number Generator) SoC is applied.

The classical communication networks of local governments below the city and provincial civil defense alarm control centers are composed of non-QUANTUM CHannel, but the best enhanced security technologies such as PUF Chip, eFUSE Chip, TRNG Chip, and FIDO authentication are applied.

FIDO is an abbreviation of 'Fast IDentity Online' (fast online authentication), and it is a technology that performs personal authentication more conveniently and safely by using biometric technology without an ID and password in an online environment. Physical characteristics such as fingerprints and irises are mainly used, and biometric information authentication of behavioral characteristics such as motions is also used.

In December 2014, more than 200 global companies, including Samsung Electronics, Google, and Microsoft, announced 'International Authentication Technology Standard FIDO 1.0', which enables safe authentication using biometric technology. We are actively providing basic financial services.

The present invention is a BB84 or COW quantum communication network using quantum entanglement and PUF that cannot be physically reproduced during the semiconductor chip production process, or PIN (Personal Identification Number) DATA of eFUSE first developed by IBM and IDQuantiqe-SK Telecom. It is related to a hybrid quantum communication network or classical communication network that combines a quantum communication network using a QUANTUM KEY using the developed QRNG (Quantum Random Number Generator) random number and a non-quantum communication network.

In addition, it is related to a hybrid quantum communication network in which QUANTUM KEY and FIDO (Fast IDentity Online) authentication are combined.

As a quantum security system based on QUANTUM Communication, it is related to a quantum security system that operates a hybrid lease network of quantum communication and ISP (Internet Service Provider) operators (fixed IP, dynamic IP) communicating through optical cable dedicated lines.

The recommended measurement range of the ultrasonic distance meter is based on about 15m, and if the error range must be stable even at a long distance of 100m or longer, a laser distance meter is used.

In the present invention, a laser distance meter is additionally used to convert the focal length (f) of the centralized surveillance camera into a target distance to improve use or measurement accuracy.

Infrared human body detection sensor (PIR sensor, Passive Infrared Sensor) is also used for the purpose of detecting a moving human body by using the spontaneous polarization effect, but on the contrary, it is used by applying additional motors and shutters to detect a still human body.

In the present invention, the mechanical contact or mechanical motion improves the conventional problem of high failure rate.

In addition, when a separate infrared camera is installed for night photography or an infrared filter is applied by driving a motor at night, black and white images are displayed, and expensive software for coloring is applied to solve the problem of black and white images. By applying an eye-level camera that combines a general low-cost visible ray ultra-low camera and dimming control lighting, a hybrid black box type surveillance camera with a high cost-effectiveness compared to functionality is implemented.

A server is a computer that stores information commonly used in one computer in a communication network connecting several computers with a communication line, or a computer that collects programs that use a lot of computer resources such as memory. Other computers connected to the communication network retrieve and receive necessary information from the server, or send data to be processed by the program in the server and receive the result back, and these are called clients. In some cases, information and programs are not concentrated in one computer, but each computer has information and programs in a distributed manner. In this case, all computers have a server/client relationship with each other. In the Internet, a computer that provides information is called a web server, and a computer that accesses the web server and searches for information becomes a client.

A microprocessor is a TTL or CMOS IC that moves only according to the set characteristics, but a microprocessor allows the manager to inject a program into the processor to implement the desired operating characteristics. It is automatically controlled according to the processor map determined to be present, and it is manufactured in the form of USB (Universal Serial Bus) or PCI Board (Peripheral Component Interconnect Board) equipped with a microprocessor (or MCU (Micro Control Unit)) to replace the server. .

A pyroelectric infrared sensor (PIR sensor; Passive InfraRed Sensor) is a representative motion detection sensor that detects a moving human body using a spontaneous polarization effect. PIR sensor) has been additionally installed to detect and use different sensing areas, but in the present invention, one or more PIR sensors detect the same sensing space, and in the detection purpose, detection method, and PIR sensor utilization method It has a difference from prior art.

In addition, due to the nature of the PIR sensor that detects only moving bodies, there has been a prior art that detects a still human body by additionally applying a motor and shutter to detect a still human body. However, since it is based on mechanical motion, efficiency and failure rate There has been a growing problem with this.

Using electronic contacts with a lower failure rate than mechanical contacts, two or more PIR sensors, which are currently mass-produced at low cost and generally cost less than $1, are used to generate human body detection, moving body detection, and stationary human detection events and use them as automatic control event data. do.

Do not use expensive cameras that use the infrared range, such as infrared (IR) cameras, infrared (IR) projectors, and thermal imaging cameras.

In particular, it is characterized by applying an ultra-low visible ray range camera that shoots through visible light illumination to which a PIR sensor is applied, rather than a method of coating a color image with expensive software on a black and white image taken by an infrared (IR) camera.

The present invention is a security system capable of super-directional warning broadcasting combined with a super-directional broadcasting system capable of warning broadcasting only for the centralized surveillance area of control personnel in an integrated crime prevention center, which controls a super-directional ultrasonic speaker according to the focal length of a surveillance camera make it a task

In particular, a sound wave conversion technology that improves conversion efficiency and clarity when an ultrasonic frequency is converted into an audible frequency at a broadcast target point through an ultrasonic speaker, and a technology that matches the broadcast target point and the target point of a centralized surveillance camera, to change the target distance. The main task is to change the ultrasonic frequency and output according to the

CCTV surveillance cameras for crime prevention generally monitor and monitor images recorded with a main camera composed of a pan/tilt camera and a fixed camera at a height of 4 to 6 m.

Although there is a subminiature camera in the video emergency bell, usually when the emergency bell push button is operated, power is supplied to make a two-way video call, and there is no surveillance function for normal security.

If a camera on the top of the enclosure that can accurately capture the face of a human object at the height of a human face is applied, it will be very effective in preventing blind spots and recognizing faces.

However, while transmitting video from one pan/tilt camera and one fixed fisheye camera or from one pan/tilt camera and four to six fixed 360-degree cameras from one location IP, additionally 4 to 9 images taken from the top of the enclosure are transmitted. Sending camera images to the CCTV control center (integrated crime prevention center) and storing them in memory for 30 days is costly.

In particular, the expansion of storage devices in the CCTV control center (integrated crime prevention center) according to the expansion of security cameras causes not only the cost of storage devices, but also problems that cannot be solved by simply increasing the total floor area of buildings. .

In particular, the fisheye camera has severe distortion, especially in the center, so the crime prevention function cannot be expected. Since it shoots from the top to the bottom, it is impossible to recognize a person's face, and only the person's head is filmed as it moves toward the center, so the crime prevention function is not effective. could not be expected

According to the present invention, the upper camera of the enclosure at an eye height of 1.5 to 3M from the ground can capture a person's face through eye-level camera shooting without distortion like a fisheye camera.

The integrated crime prevention center monitors monitor about 50 surveillance camera images, but in practice, they have no choice but to intensively monitor only 1 or 2 images.

In normal times, the video is stored in a black box type, and only when an emergency bell is activated or an abnormal sound source is detected, it is transmitted to the control center through the wireless communication network. Receives data through the network of wireless telecommunications carriers of the integrated rate plan that is deducted.

QUANTUM PUBLIC KEY, QUANTUM PRIVATE KEY through QRNG (Quantum Random Number Generator) SoC and unique PRIVATE KEY security through PUF (Phisycally Unclonable Function) Chip or eFUSE first developed by IBM as a task for classical communication network .

In the field of IoT communication, a device generates a password on its own using a new technology called eFUSE/PUF and uses it for authentication to identify each other between devices and perform security authentication to verify whether they are legitimate entities at a reliable level. A device and method are provided.

In particular, quantum coherence and pulse arrival time are randomly selected and measured on a dedicated line connected by optical cables of IDQuantiqe S.A. Quantum communication and quantum communication are characterized by being composed of qubits with non-empty pulse positions and defending against coherence attacks with decoy pulses (decoi-PULSE DEBUGGER). It is a quantum communication system that strengthens security through quantum authentication of data in ISP (Internet Service Provider) operator rental (dedicated/own) networks that do not form communication channels.

In the application of a device or system in which secure communication using encryption/decryption performs machine intelligence communication, a security authentication device and method robust against physical attacks or unauthorized access to the security authentication system of the device are provided.

Despite high security such as quantum cryptographic security, there is no comparable technology and there is no authentication standard such as NIS CC certification, so a technology such as NIS CC certified SSL-VPN is added, but the more security, the more there will be no shortage. .

By detecting the same detection area through a multi-pyroelectric infrared sensor (PIR; Pyroelectric InfraRed), the first state (human body not detected), the second state (dynamic human body), the third state (human body stopped, passing), the fourth state ( Human body stop) is detected, the lighting is dimmed, and the original color image is taken and stored in a black box format with an ultra-low-angle general camera (visible light).

Equation: (Single/Dual ultrasonic speaker + Quad ultrasonic speaker + Matrix ultrasonic speaker) * (39kHz + 41kHz) * (surveillance camera focal length variable + laser distance meter variable) * (power amplifier variable)

Function Formula 1: F(x) = QKD Key(QRNG)

Function Expression 2: F(x) = DATA RECORDER Key (QRNG+PRNG)

Function Expression 3: F(x) = DATA STORAGE Key (QRNG+PRNG)

As an example,

1st (39kHz), 2nd (41kHz), 3rd (39.5kHz), 4th ( 40.5 kHz) in a quad ultrasonic speaker composed of an ultrasonic speaker,

In the case of super-directional broadcasting to a short-range target point of the first distance (within 10M), firstly applied (odd-numbered) ultrasonic speakers apply No. 1 and 2, then apply No. 3 and 4 ultrasonic speakers (even-numbered/sensor modules) next. Circular application (prevents the intensive use of only one ultrasonic speaker)

In the case of super-directional broadcasting to a mid-range target point of the second distance (within 10 to 50M), quad ultrasonic speakers numbered 1 to 4 are applied.

In case of super-directional broadcasting to a long-distance target point of the third distance (more than 50M), increase the volume by increasing the power amplifier output of the Quad ultrasonic speaker, or use a 3×3 or more parallel (Matrix) ultrasonic speaker apply

By applying a single ultrasonic speaker or a dual ultrasonic module, a quad ultrasonic speaker with a frequency difference such as 1kHz to 2kHz is applied.

As an example,

As shown in Function Equation 1, encryption/decryption is performed with a Quantum Random Number Generator (QRNG) Quantum Key as a quantum random number seed in a quantum communication QKD (Quantum Key Distribution) section.

As shown in Function Equation 2, the captured image is encrypted/decrypted and stored using a Program Random Number Generator (PRNG) and a Quantum Random Number Generator (QRNG) hybrid random number seed key.

Data is encrypted/decrypted and stored using a Program Random Number Generator (PRNG) and a Quantum Random Number Generator (QRNG) Hybrid-QUANTUM Key, as shown in Function Formula 3 above.

FIDO2 (Fast IDentity Online 2) is applied for Log IN/OUT access to server and storage device.

As an example,

In the case of generating a cancer/crypto key with only a random positive random number seed, if the cancer/crypto key is not known, cancer/crypto is impossible.

When encryption/decryption keys are generated by using a pseudorandom number seed generated by a program random number generator (PRNG) by an operator or by various well-known key generation methods, the larger the number of terminals or key generation, the more program regularity is identified. It becomes easier and more vulnerable to hacking attacks.

When a random positive random number seed and a pseudorandom number seed are used as an operator or a key generation method of various well-known methods is used to generate encryption/decryption keys, when the pseudorandom number seed and key generation method are known You can create encryption/decryption keys.

In the above case, security is high because a key is generated with a non-regular random quantum random number seed every time a terminal and a key are generated.

Function Formula 1: F(x) = QKD Key(QRNG)

Function Expression 2: F(x) = DATA RECORDER Key (QRNG+PRNG)

Function Expression 3: F(x) = DATA STORAGE Key (QRNG+PRNG)

As shown in Function Equation 1, a quantum key is generated with a quantum random number seed of a QRNG (Quantum Random Number Generator) in a quantum communication QKD (Quantum Key Distribution) section.

As shown in the function formula 2 above, the captured image taken from the surveillance camera is encrypted/decrypted and stored with a hybrid-QUANTUM key that combines a Program Random Number Generator (PRNG) and a Quantum Random Number Generator (QRNG).

As shown in Functional Formula 3, data is encrypted/decrypted and stored by generating a Hybrid-QUANTUM Key according to a PRNG (Program Random Number Generator) and QRNG (Quantum Random Number Generator) operator or a known key generation method. .

FIDO2 (Fast IDentity Online 2) is applied for Log IN/OUT access to server and storage device.

For example,

The MCU (Main Control Unit) inside the edge server, which includes the QRNG (Quantum Random Number Generator) chip-mounted security module, generates the same pseudorandom number seed through the PRNG (Program Random Number Generator) program. Seed) PRN (Program Random Number) is generated and quantum random number QRN (Quantum Random Number) is generated and received through the QRNG Chip inside the security module.

The MCU inside the edge server generates an encryption/decryption key by calculating the PRN seed key and QRN seed key as a function formula F(x) = DATA RECORDER Key (QRNG+PRNG).

For example, there has been a classical method such as EX-OR or EX-AND to calculate the PRN seed key random number and the QRN seed key random number.

In the above case, if the PRN seed key random number and operators such as EX-AND are known, the QRN seed key random number can be known to generate a decryption key, and different keys can be generated through random and irregular QRN seed key random numbers.

This is why conventional encryption programs can be hacked if they interpret the PRNG regularity.

The operator applies various known encryption methods such as a conventionally known hash function and AES.

The MCU inside the edge server encrypts the image data captured by the surveillance camera with an encryption/decryption key and stores it in the storage device.

CCTV for security or integrated security lights Black box type CCTV supports are 4m, 5m, and 6m, and security cameras are attached to each upper layer.

In the case of a lamp arm, a security camera is attached at a height of about 5.7 m.

The video emergency bell is a combination of a small camera and an emergency bell, and is installed between 1.5m and 3m.

In the integrated crime prevention center, it is recommended that one control agent monitor the images taken by surveillance cameras of less than 50 units, but in the field, it is easy to find cases where more camera images are monitored.

Therefore, it is possible to intensively monitor the event video through various intelligent analyzes such as the fall of the sound source such as the abnormal sound source "Please help me" and the recorded video, merging/collecting, weapon object recognition, and abnormal sudden behavior analysis.

As for the video captured by the surveillance camera according to the present invention, at least one pan/tilt camera, four fixed cameras, and one to four fisheye cameras should be used to process images taken by at least six surveillance cameras.

Rather than processing the individual images of IP cameras in the integrated crime prevention center, it is more efficient to transmit the integrated images pre-processed by the local edge server to the integrated crime prevention center and store them in large-capacity storage for less than 30 days. It is a technical task of the present invention to propose that 9 individual images are stored in a local edge server for 30 days, and that the integrated crime prevention center transmits an integrated image that does not interfere with monitoring, or transmits one integrated image and a video taken by a main camera. .

The present invention applies a conventionally known method in which an event image selected by various known methods such as abnormal sound source and object behavior analysis is popped up on a monitor and monitored by a monitor personnel.

However, with the specialized technology of the present invention, usually 1 or 2 compressed images are transmitted, but when adopted as an event image, augmented reality including an image taken with an eye-level camera through the individual monitor of the monitor agent under the control of the monitor agent It is characterized by displaying through an image.

Through OTP QUANTUM KEY authentication, the local edge server receives air raid/disaster risk/disaster warning/nurturing/TTS broadcasting data issued from the civil defense alarm control center or disaster situation room through civil defense/disaster warning emergency bell, and uses its own amplifier-integrated speaker of 20W or more. broadcast through

In the present invention, in addition to the video taken at a height of 4 to 6 m, blind spots around the CCTV post are prevented through 360-degree shooting at a height of 1.5 m to 3 m.

As described above, structural stability is increased because the arm is not required or may be short to prevent blind spots around the post.

Create a physically non-replicable private key (PRIVATE KEY) through PUF (Phisycally Unclonable Function) Chip or eFUSE System On Chip.

It is characterized by encoding unique biometric information with a public key generated through an unpredictable QRNG (Quantum Random Number Generator) Chip through a small USB fingerprint recognition device that is easy to carry.

PUF (Phisycally Unclonable Function) Chip, a physically unique chip that cannot be duplicated, or a unique PRIVATE KEY through eFUSE first developed by IBM and QRNG (Quantum Random Number Generator) developed by SK Telecom and ID Quantique SA FIDO authentication based on QUANTUM public key (PUBLIC KEY) that encrypts biometric information such as fingerprint with OTP QUANTUM KEY (One Time Password QUANTUM Key) generated through A quantum communication network through a quantum security platform (Quantum-Platform) using hybrid quantum communication interval encryption or quantum key distribution QKD (Quantum Key Distribution) of is applied.

It will be described through an example.

As an example, briefly described, the first PIR sensor and the second PIR sensor are normal PIR sensors, but the first PIR sensor supplies a positive voltage of a square wave, and the second PIR sensor supplies a negative voltage of a square wave. Depending on the application of the response time of the sensor, the overlapping part of the square wave occurs as shown in FIG. 1.)

It is applied to night mode below.

First state: In the case of the first state (human body not detected) in the spontaneous polarization state through the first PIR sensor (Pyroelectric Infrared (PIR) sensor), lighting is turned off.

2nd state: When the 1st PIR sensor detects a moving human body in the 2nd state (dynamic human body) in the state of despontaneous polarization, the light turns on. (At this time, the driving power of the 2nd PIR sensor is OFF)

3rd state: In the 3rd state (human body stopped or passed) in which the first PIR sensor returns to the spontaneous polarization state, the lighting maintains the ON state for the manager input time (sensor response time of about 10 seconds or longer) and the second PIR sensor Drive power is supplied through drive power ON.

4th state: When the first PIR sensor is in a spontaneous polarization state and the second PIR sensor is in a despontaneous polarization state, in the fourth state (human body stopped), when the light is kept ON or when the first and second PIR sensors are in a spontaneous polarization state Illumination is turned off in the first state (no human body detected).

For example, the second PIR sensor can be replaced with an interrupt register ON/OFF control applied with a shutter-type chopper.

It is a crime prevention CCTV surveillance camera system capable of super-directional broadcasting that minimizes noise complaints. It improves clarity by controlling the ultrasonic speaker module according to the target setting through the surveillance camera and the target distance change.

It has the effect of improving performance with enhanced security for surveillance without blind spots and distortion and effective dissemination of civil defense/disaster warning.

Installation is simple through the smart emergency bell, which is integrally manufactured with all equipment, functions, and additional elements necessary for the conventional security CCTV system, except for the security camera and arm, in the emergency bell integrated enclosure.

The top camera (eye-level camera) installed on the top of the enclosure is an ultra-low-level surveillance camera that takes color pictures of the general visible ray region. It is stored as a black box without any

1 to 4 are explanatory diagrams for understanding the invention

It consists of an edge server, a sensor unit (multi-spontaneous polarization sensor), a monitoring camera, and a broadcasting device.

The sensor unit (multi-spontaneous polarization sensor) is a power supply unit module on a single board substrate inside a single housing, unlike a dual or quad pyroelectric infrared sensor (PIR sensor; Passive InfraRed Sensor) that detects different spaces. The first pyroelectric sensor detection module and the second pyroelectric sensor detection module are disposed to detect the human body in the same space. Two or more PIR sensor modules are installed on one substrate to detect the same space.

The edge server supplies initial driving power to the first pyroelectric infrared sensor through a power supply unit, and is initialized in an equilibrium phase in which a spontaneous polarization equilibrium state is maintained.

After the initial equilibrium phase, the edge server detects a moving body with the first pyroelectric sensor and switches from the spontaneous polarization equilibrium state to the unbalanced state. Supply driving power to the sensor.

Since the PIR sensor requires the time required for stabilization after being supplied with driving power, moving object detection step recognizing it as a spontaneous polarization unbalanced state even if it is switched from a spontaneous polarization imbalance state to an equilibrium state during the stabilization time of the manager input value programmed into the edge server. is needed

For example,

If the stabilization time of the administrator input value programmed into the edge server is set to 60 seconds, even if the 1st pyroelectric sensor is converted from spontaneous polarization imbalance to equilibrium within 60 seconds, spontaneous polarization occurs within 60 seconds This is a moving object detection stage that recognizes an unbalanced state.

The time of 60 seconds varies according to the administrator input time (stabilization time) programmed into the edge server, for example.

In addition, if the time of 60 seconds is divided by the 2-1 PIR sensor and the 2-2 PIR sensor instead of the second PIR sensor to reduce the error, it can be divided into 30 seconds + 30 seconds.

That is, the first PIR sensor is used for detecting a moving body, and the 2-1 PIR sensor and the 2-2 PIR sensor are used for the purpose of detecting a still human body and reducing stabilization time errors.

In the motion detection step, motion detection event data is generated and provided to a terminal device (surveillance camera, broadcasting device, automatic control device, operating device such as lighting, switchboard, etc.).

After the moving body detection step, the edge server cuts off driving power to the second PIR sensor in a state where the first PIR sensor and the second PIR sensor maintain a spontaneous polarization equilibrium state, and the moving body and the stationary human body are not inside the sensing area. and returns to the initial equilibrium stage to generate event data that is judged as movement of the moving body, or when the second PIR sensor is driven by the edge server and converted from the spontaneous polarization equilibrium state to the unbalanced state and a human body detection event signal is received, the human body is in a stopped state This is an analysis step of cutting off the driving power to the second PIR sensor and switching to the moving object detection step after determining to be .

As an example,

Function Formula 1: F(x) = QKD Key(QRNG)

Function Expression 2: F(x) = DATA RECORDER Key (QRNG+PRNG)

Function Expression 3: F(x) = DATA STORAGE Key (QRNG+PRNG)

As shown in Function Equation 1, encryption/decryption is performed with a Quantum Random Number Generator (QRNG) Quantum Key as a quantum random number seed in a quantum communication QKD (Quantum Key Distribution) section.

As shown in Function Equation 2, the captured image is encrypted/decrypted and stored using a Program Random Number Generator (PRNG) and a Quantum Random Number Generator (QRNG) hybrid random number seed key.

Data is encrypted/decrypted and stored using a Program Random Number Generator (PRNG) and a Quantum Random Number Generator (QRNG) Hybrid-QUANTUM Key, as shown in Function Formula 3 above.

FIDO2 (Fast IDentity Online 2) is applied for Log IN/OUT access to server and storage device.

As an example,

In the case of generating a cancer/crypto key with only a random positive random number seed, if the cancer/crypto key is not known, cancer/crypto is impossible.

When encryption/decryption keys are generated by using a pseudorandom number seed generated by a program random number generator (PRNG) by an operator or by various well-known key generation methods, the larger the number of terminals or key generation, the more program regularity is identified. It becomes easier and more vulnerable to hacking attacks.

When a random positive random number seed and a pseudorandom number seed are used as an operator or a key generation method of various well-known methods is used to generate encryption/decryption keys, when the pseudorandom number seed and key generation method are known You can create encryption/decryption keys.

In the above case, security is high because a key is generated with a non-regular random quantum random number seed every time a terminal and a key are generated.

FIDO2 (Fast IDentity Online 2) is applied for Log IN/OUT access to server and storage device.

For example,

The MCU (Main Control Unit) inside the edge server, which includes the QRNG (Quantum Random Number Generator) chip-mounted security module, generates the same pseudorandom number seed through the PRNG (Program Random Number Generator) program. Seed) PRN (Program Random Number) is generated and quantum random number QRN (Quantum Random Number) is generated and received through the QRNG Chip inside the security module.

The MCU inside the edge server generates an encryption/decryption key by calculating the PRN seed key and QRN seed key as a function formula F(x) = DATA RECORDER Key (QRNG+PRNG).

For example, there has been a classical method such as EX-OR or EX-AND to calculate the PRN seed key random number and the QRN seed key random number.

In the above case, if the PRN seed key random number and operators such as EX-AND are known, the QRN seed key random number can be known to generate a decryption key, and different keys can be generated through random and irregular QRN seed key random numbers.

This is why conventional encryption programs can be hacked if they interpret the PRNG regularity.

The operator applies various known encryption methods such as a conventionally known hash function and AES.

The MCU inside the edge server encrypts the image data captured by the surveillance camera with an encryption/decryption key and stores it in the storage device.

After the first manager input time (eg, 0 seconds to 60 seconds), the main control unit turns on the dimming lights for a second manager input time (eg, 60 seconds to 100 seconds) and then turns off the lights. .

After the first manager input time (at 60 seconds) ends, the main control unit supplies driving power to the second PIR sensor (at 60 seconds). (Or supplies driving power at 10 seconds.)
