Description

TECHNICAL FIELD

[0001] The present application relates to the field of intelligent communication technology, in particular to an intelligent access control communication method and system based on star flash relay gateway cooperation. BACKGROUND

[0002] Most of the current intelligent access control collects video images outside the door through a camera and transmits them to a user terminal to realize visitor confirmation and security protection. However, using video pictures as the only visitor authenticity credential lacks effective on-site verification means, resulting in risks such as pre-recording, screen flipping, and deep forgery of video content, making the identity verification link have significant anti-fake vulnerabilities and being difficult to effectively distinguish between real visitors and fake attacks. Once the video pictures are tampered with, it is difficult to accurately determine the true situation of the person outside the door, thereby causing security risks, and the credibility and security level of the remote video access control are obviously restricted. On the other hand, in order to realize functions such as video collection, data transmission, remote communication, and alarm pushing, many door locks are connected to the home network through Wi-Fi, but Wi-Fi has high power consumption in standby and working states, which limits the endurance time of the door lock, and users need to charge frequently or replace the battery, affecting long-term use experience.

[0003] In summary, the existing technology has the technical problem that since the intelligent access control is mostly video transmission, there are anti-fake vulnerabilities and high power consumption problems, which limit both security and endurance, further affecting the protection capability of the intelligent access control.

[0022] This application provides a smart access control communication method and system in collaboration with a StarFlash relay gateway. It addresses the technical problems in existing technologies where smart access control systems, primarily relying on video transmission, suffer from anti-counterfeiting vulnerabilities and high power consumption, resulting in limited security and battery life, further impacting the security capabilities of smart access control systems. By employing a StarFlash relay gateway to achieve ultra-low power connection and adding an audio-visual anti-counterfeiting sensing module, high-frequency flashing light signals are uploaded to a cloud server as evidence to verify the authenticity of the video. Once verified, the video is pushed to the user, enabling verifiable video authenticity and extended door lock battery life, thereby improving the security of the smart access control system.

[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings.

It should be understood that this application is not limited to the exemplary embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. It should also be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all of them.

[0024] Example 1, please refer to the appendix. Figure 1 This application provides a smart access control communication method in collaboration with a StarSignal relay gateway. The method is applied to a smart access control communication system in collaboration with a StarSignal relay gateway, and specifically includes the following steps: An audio-visual anti-counterfeiting sensing module is set in the access control module, and the access control module and the audio-visual anti-counterfeiting sensing module are communicatively connected to at least one relay gateway.

[0025] Specifically, the access control module is the core execution and decision-making unit of the intelligent access control system. Typically installed on the door, it integrates the main processor, a communication module, and door lock drive circuitry. It is responsible for performing core functions such as facial recognition, fingerprint verification, and receiving remote commands to control the door lock opening and closing; it is the brain of the entire access control system. The sound and light anti-counterfeiting sensing module is a multimodal liveness detection and anti-counterfeiting sensor cluster. It verifies the authenticity of the environment through the combined use of two physical signals. It includes an sound sensing module and a light sensing module. The core of the sound sensing module is an ultrasonic transceiver, which can both emit ultrasonic waves of a specific frequency and receive echoes. It detects the authenticity of the environment by analyzing the propagation characteristics of sound waves in physical space. The core of the light sensing module is an LED array and LED driver circuitry. The driver circuitry precisely controls the on / off timing and intensity of each LED, thereby emitting a coded high-speed flashing light signal that is imperceptible to the human eye.

[0026] The StarShine Relay Gateway is a communication hub and device. The StarShine door lock and the StarShine Relay Gateway are connected via StarShine. The StarShine Relay Gateway connects to a Wi-Fi router uplink and to the StarShine door lock downlink. The StarShine door lock can then transmit images and videos to a mobile phone via the relay gateway, enabling the phone to view real-time images outside the door. When the door lock enters low-power mode, it can maintain keep-alive and remote wake-up functions through the StarShine connection with the relay gateway. Keep-alive mode means that the device maintains a minimum network connection to handle tasks such as heartbeat signals and remote wake-up commands even when not explicitly woken up, similar to standby mode. In terms of power consumption, the StarShine connection is more than half as efficient as the Wi-Fi connection in both keep-alive and operational aspects, thus meeting the door lock's long battery life requirements. The StarShine door lock module deployed on the door lock terminal, and the StarShine Relay Gateway as the communication hub, work together to reconstruct the underlying connection logic of the smart access control system, achieving a breakthrough by requiring only ordinary dry-cell batteries for power to the door lock while ensuring a complete smart experience.

[0027] The StarShine door lock module, embedded as a lightweight terminal within the lock body, handles only core functions such as image acquisition, door lock control, and StarShine communication. Its biggest innovation lies in completely eliminating reliance on lithium batteries. The StarShine door lock module consumes extremely low power in its sleep / keep-alive state, and its energy efficiency is significantly optimized during activation and transmission, allowing ordinary alkaline batteries to support stable operation for months or even a year. The StarShine relay gateway, acting as a local hub, is deployed near indoor power outlets and performs the crucial function of bidirectional protocol conversion. Downlink, it establishes a reliable, encrypted, low-power connection with the door lock module via the StarShine protocol; uplink, it accesses the internet and cloud servers via home Wi-Fi or Ethernet. The StarShine protocol is deeply optimized for IoT scenarios, and its microsecond-level wake-up mechanism and efficient data transmission architecture enable a significant reduction in power consumption for the door lock module in both critical states. Standby power consumption is reduced by over 50%. When the door lock is in sleep mode, the StarShine link only needs to maintain a micro-current-level heartbeat connection to ensure device online reachability, with power consumption far lower than the baseline power consumption of maintaining a long TCP connection with Wi-Fi. Working transmission power consumption is reduced by over 50%. When users remotely wake up the door lock or trigger video transmission, StarSpark's high-efficiency RF design significantly reduces the peak power consumption of high-definition image streaming. The door lock completely eliminates the need for bulky lithium batteries and complex charge / discharge protection circuits, requiring only four AA dry batteries to achieve an ultra-long battery life of over 12 months, fundamentally eliminating the hassle of frequent charging or battery replacement for users.

[0028] Users can remotely wake up the door lock at any time via a mobile app. The StarSpark link is instantly activated and transmits 1080P high-definition video to the gateway, which is then relayed to the cloud via Wi-Fi, achieving seamless linkage between the mobile phone, cloud, gateway, and door lock, keeping users fully informed about what's happening outside the door. The StarSpark door lock module supports dynamic detection algorithms, such as motion detection and abnormal lock-picking vibration sensing. Once a risky behavior is identified, an encrypted alarm signal is immediately sent to the gateway via the StarSpark link and pushed to the user's mobile phone within 5 seconds, achieving a closed-loop proactive defense of perception, decision-making, and early warning. During the door lock's deep sleep period, StarSpark's unique sub-millisecond wake-up technology ensures that gateway commands can instantly activate the device, with no perceptible delay for remote operation by the user, breaking the technical paradox of not being able to achieve both low power consumption and instant response.

[0029] The access control module establishes a low-power communication connection with at least one relay gateway via the StarFlash protocol, enabling reliable transmission of access control video signals to the relay gateway. The relay gateway, acting as a bridging node, uploads data collected by the access control module to a cloud server, enabling video authenticity verification and remote monitoring. This ensures that the access control module can still be remotely woken up by the gateway even when in low-power standby mode, and supports real-time triggering of audio-visual signal generation and video capture, ensuring that the video and anti-counterfeiting signals are synchronized and verifiable. By fusing two different dimensions of physical signals—light and sound—for cross-verification, a very strong anti-counterfeiting barrier is formed. It is virtually impossible for attackers to simultaneously, synchronously, and accurately forge two different types of physical signals, greatly enhancing the security level of the access control system.

[0030] When a visitor enters the access control identification area, the access control video signal of the access control module is collected, and at the same time, the audio-visual anti-counterfeiting sensing module is triggered to obtain audio-visual sensing signals, which include flashing light signals and ultrasonic signals.

[0031] Furthermore, this application also includes the following steps: triggering the sound and light anti-counterfeiting sensing module to obtain sound and light sensing signals, wherein the sound and light anti-counterfeiting sensing module includes a sound sensing module and a light sensing module, wherein the sound sensing module includes an ultrasonic transceiver, and the light sensing module includes an LED array and an LED driving circuit; when a visitor enters the access control identification area, the sound and light anti-counterfeiting sensing module is triggered, wherein the sound sensing module outputs an ultrasonic signal through the ultrasonic transceiver, and the light sensing module drives the LED array to output a flashing light signal through the LED driving circuit.

[0032] Furthermore, this application also includes the following steps: triggering the sound and light anti-counterfeiting sensing module to generate an encrypted session certificate, the encrypted session certificate including an identifier and a timestamp; transmitting a beacon signal containing the encrypted session certificate to the ultrasonic transceiver and outputting an ultrasonic signal; simultaneously using the encrypted session certificate for encoding and modulation, and then driving the LED array to output a flashing light signal through an LED driving circuit.

[0033] Specifically, the access control recognition zone refers to the designated sensing area in front of the access control system. It is typically not a two-dimensional plane, but a three-dimensional space, precisely defined by the detection range of a passive infrared sensor or millimeter-wave radar. For example, it can be set as a rectangular area of ​​2 meters by 1.5 meters in front of the door, with a height exceeding 2 meters, ensuring effective identification when an adult approaches. When a visitor enters the access control recognition zone, the access control module immediately triggers video capture and enters working mode. It acquires the raw video data stream through the high-definition camera integrated on the module, obtains the access control video signal, and stores the data in a buffer.

[0034] Simultaneously, the sound and light anti-counterfeiting sensing module is triggered, and its internal microcontroller synchronously drives two sub-modules: the sound sensing module and the light sensing module. The sound sensing module contains an ultrasonic transceiver for outputting and receiving sound wave signals of specific frequencies, such as 40kHz, forming part of the anti-counterfeiting signal. The complete ultrasonic signal includes the transmitted waveform and the received echo. The light sensing module contains an LED array and LED driving circuitry, which modulates the light signal through high-speed flashing, such as 800-1500Hz visible or invisible strobe, forming the anti-counterfeiting light signal. The LED driving circuitry receives coded data from the same microcontroller and, at an extremely high switching speed, such as a 100Hz baseband square wave, controls each LED in the LED array to emit a strong, imperceptible flashing light that is indistinguishable to the human eye due to the persistence of vision. This light signal covers the entire access control identification area.

[0035] For example, a high-end tablet computer plays a pre-recorded video of a real visitor opening a door. When the tablet is placed in the access control recognition area, the audio-visual anti-counterfeiting sensing module is successfully triggered. At timestamp T0, the human infrared sensor detects movement and triggers an interrupt; at timestamp T0+5ms, the camera begins outputting the first frame of video data; at timestamp T0+5ms, the audio-visual module microcontroller simultaneously starts ultrasonic wave transmission and LED driving. The LED array immediately begins flashing with a reference light pulse at a frequency of 100Hz and a duty cycle of 80%. The ultrasonic transducer emits a pulse train with a center frequency of 40.0kHz±0.5kHz. During the subsequent 3-second verification period, the video stream captured by the camera includes image content from the tablet screen and high-frequency flashing light signals generated by the access control system's own LEDs. Simultaneously, the echo signal collected by the ultrasonic receiver has time-domain envelope and frequency-domain characteristics that differ significantly from the model of the real three-dimensional space, thus the access control recognition fails.

[0036] The audio-visual anti-counterfeiting sensing module enables the synchronous acquisition of video frames and audio-visual signals, forming a unique dual-channel anti-counterfeiting feature. The audio-visual signals provide strong evidence when verifying the authenticity of the video in the cloud, significantly reducing the risk of being misled into unlocking the door by counterfeit videos. Simultaneously, the use of StarFlash low-power communication maintains the access control module's long battery life and remote wake-up capability, achieving a smart access control experience that combines high security with low energy consumption.

[0037] When the access control system triggers the audio-visual anti-counterfeiting sensing module, its internal security chip immediately takes action. It retrieves an 8-byte random number from a random number generator as the identifier for the current session, and simultaneously reads a timestamp accurate to milliseconds from a real-time clock. The encrypted session credential is a dynamically generated, one-time-use, one-key digital identity, a unique credential created solely for each verification event, similar to a one-time transaction token in online banking. The encrypted session credential includes an identifier and a timestamp. The identifier, a pseudo-random number, uniquely identifies the current access control verification session and is typically generated by a true random number generator to ensure uniqueness across different events. The timestamp precisely records the generation time to prevent replay attacks. The internal security chip uses a pre-set key to encrypt the data packet containing the identifier and timestamp, generating the encrypted session credential.

[0038] The sound sensing module transmits a beacon signal carrying session credential information via an ultrasonic transceiver, forming a high-frequency pulse sequence to generate an ultrasonic signal. Simultaneously, the LED driver circuit modulates the LED array with high-frequency flashing based on the same encrypted session credential, embedding the light signal into the brightness changes of the video frame. Both the ultrasonic signal and the flashing light signal are time-synchronized with the video frame, ensuring the uniqueness and timeliness of each authentication. For example, if the access control module is triggered at time T1, generating a new encrypted session credential with a timestamp of t0=1717824005123, corresponding to June 8th 12:00:05.123, the ultrasonic channel transmits a beacon signal carrying this new credential. The attacker's voice recorder plays the sound wave corresponding to the old credential, with a timestamp of t1=1717823945000. The optical channel synchronously transmits flashing light carrying the new credential, while the attacker's camera plays the old light signal. Upon receiving the signal, the cloud server first decrypts and checks the timestamp. It finds that the timestamp t0 of the ultrasonic channel differs from the current time by 60 seconds, far exceeding the allowed ±3-second time tolerance window. Therefore, it immediately determines this verification is a replay attack and the verification fails. Simultaneously, the timestamp t1 obtained by the cloud from decoding the optical signal in the video is new and does not match the timestamp t0 of the ultrasonic signal.

[0039] By using dynamic credentials and dual-channel transmission, the uniqueness and timeliness of each authentication are ensured. At the same time, the output includes an ultrasonic beacon containing encrypted session credentials and a coded and modulated flashing light signal, which can achieve precise synchronization and encrypted association between access control video and audio-visual signals. This effectively prevents forgery or playback of video. Even if an attacker records a legitimate audio-visual signal, it becomes useless because it expires quickly.

[0040] Furthermore, this application also includes the following steps: obtaining a preset carrier frequency, and the LED driving circuit adjusting the encoding rate of the encrypted session credential to the preset carrier frequency to output a flashing light signal.

[0041] Specifically, based on the camera's performance and ambient light noise levels, a preset carrier frequency is defined in advance. This preset LED light signal flicker frequency serves as the reference frequency for transmitting encrypted session credentials. It is typically higher than the threshold perceptible to the human eye to avoid visible flickering, while also considering the camera's acquisition performance. For example, a preset carrier frequency of 100Hz means that the LED will potentially change its on / off state 100 times per second, providing a stable fundamental frequency for data encoding.

[0042] When data needs to be sent, the LED driver circuit starts working, receiving the encrypted session credential data stream from the microcontroller. For each bit of data to be sent, a bitwise AND operation is performed between that bit and a 100Hz carrier square wave. When the data bit is 1, the driver circuit allows the 100Hz carrier to pass. Within a 10ms bit period, the LED completes one full on / off cycle, i.e., 5ms on, 5ms off, corresponding to a 50% duty cycle at 100Hz. From the camera's perspective, this appears as a distinct brightness variation cycle. When the data bit is 0, the driver circuit blocks the carrier, and the LED remains off for the entire 10ms bit period. The encrypted session credential, a simple binary sequence, is modulated into a complex optical signal containing specific frequency components in its brightness, so that the signal contains both baseband data information (0 or 1) and the characteristics of the carrier frequency.

[0043] The output of the flashing light signal is adjusted to a preset carrier frequency. This means that the presence or absence of the preset carrier frequency is controlled by the binary data stream of the encrypted session credential. Data 1 corresponds to sending a carrier signal of one duration, i.e., the LED flashes rapidly, while data 0 corresponds to keeping it off. The flashing light signal forms a brightness fluctuation curve in the video frame, corresponding one-to-one with the session credential. This allows the cloud or local decoding module to accurately extract the session credential information from the video, achieving reliable optical anti-counterfeiting verification. This ensures the integrity of the encrypted data transmitted in the light signal while avoiding bit errors caused by a mismatch between the carrier frequency and the camera frame rate.

[0044] By adjusting the encoding rate of the encrypted session credential to a preset carrier frequency to output a flashing light signal, high-precision optical anti-counterfeiting signal synchronous video frame acquisition is achieved, ensuring the integrity and decodeability of the light signal without affecting the user's visual experience.

[0045] The access control video signal and the audio-visual sensing signal are transmitted to the cloud server via the relay gateway. The cloud server performs cloud anti-counterfeiting verification on the access control video signal based on the audio-visual sensing signal and outputs the cloud anti-counterfeiting verification result.

[0046] Furthermore, this application also includes the following steps: associating the audio-visual sensing signal and the access control video signal according to the identifier and timestamp of the audio-visual sensing signal, and decoding and extracting the video optical signal of the access control video signal; comparing and verifying the video optical signal of the access control video signal with the audio-visual sensing signal according to the encrypted session credential, and outputting a cloud-based anti-counterfeiting verification result, including session identifier consistency, timestamp validity, and key correctness; if the session identifier consistency, timestamp validity, and key correctness are all verified, the cloud-based anti-counterfeiting verification result is passed.

[0047] Furthermore, this application also includes the following steps: performing video frame preprocessing on the access control video signal to output a video frame sequence; extracting key video frame sequences from the video frame sequence through an attention mechanism, wherein the attention mechanism includes regions where the light signal reflection intensity is greater than a preset intensity threshold; calculating the average brightness value of each frame in the key video frame sequence and converting it into a brightness signal waveform; and decoding the brightness signal waveform as the video light signal of the access control video signal.

[0048] Specifically, based on the audio-visual anti-counterfeiting sensing module, which collects audio-visual sensing signals, including flashing light signals obtained by the light sensing module and ultrasonic signals obtained by the sound sensing module, the access control module transmits the video signal and audio-visual signal in dual-path through the Star Flash relay gateway. The video signal serves as the main data stream, while the audio-visual signal serves as the anti-counterfeiting verification stream.

[0049] After receiving the data, the cloud server finds the exact same identifier and timestamp in the data packets of the video stream based on the identifier and timestamp of the audio-visual sensing signal. It then associates the audio-visual sensing signal with the access control video signal, aligning the timestamp of each video frame with the timestamp of the audio-visual signal. Based on the session identifier, it binds the video and signal into a logical event, ensuring that each video segment corresponds to unique anti-counterfeiting information and preventing the video from being tampered with or failing verification during playback.

[0050] The video signal captured by the camera includes the original visitor image and possible environmental noise. The access control video signal undergoes video frame preprocessing, including noise reduction, height normalization, frame sorting and cropping, and outputting a video frame sequence. Gaussian filtering is used to remove ambient light noise and sensor noise; the brightness of each frame is adjusted to the range of 0-255 to ensure consistent decoding of the video light signal under different lighting conditions; the frames are sorted according to the acquisition timestamp, and non-critical areas are cropped to obtain the final video frame sequence, with each frame retaining its timestamp information.

[0051] A rule-based attention mechanism begins working, iterating through each frame within the audio-visual event time window. For each frame, it analyzes the reflection intensity of the LED flickering area, marking areas with light signal reflection intensity greater than a preset intensity threshold as regions of interest. Only frames containing these regions are selected as key video frames. This attention mechanism ignores frames where the LED is in its off-cycle, as well as low-brightness frames caused by sudden changes in ambient light, concentrating all computational resources and analysis focus on the period of strongest and most stable signal—essentially acting as an intelligent data compression and noise reduction filter.

[0052] In chronological order, for a key video frame sequence, the average luminance value of each frame is calculated and converted into a luminance signal waveform. In other words, the average luminance values ​​of the entire key video frame sequence are arranged chronologically to form a continuous luminance signal waveform. This luminance signal waveform depicts the trajectory of the average luminance of the selected key video frame sequence's region of interest over time along the video playback timeline. The luminance signal waveform is then decoded according to predetermined encoding and modulation rules to obtain the video optical signal of the access control video signal. For example, for on / off keying modulation, an intermediate threshold is set; portions of the waveform above the threshold are decoded as binary 1s, and portions below the threshold are decoded as 0s, thus reconstructing the video optical signal. Decoding the luminance signal waveform refers to the process of reconstructing the original binary digital sequence from the luminance signal waveform in the time domain. Signal processing algorithms are used to identify characteristic patterns in the waveform, such as high levels representing 1 and low levels representing 0, and reverse analysis is performed following the same encoding rules as the transmitting end.

[0053] Based on the encrypted session credentials, namely the identifier and timestamp, the video optical signal of the access control video signal is compared and verified with the audio-visual sensing signal. This includes verifying the consistency of the session identifier, the validity of the timestamp, and the correctness of the key. Session identifier consistency is checked by comparing whether the identifier decoded from the video optical signal is completely identical to the identifier decrypted from the audio-visual signal. Timestamp validity is checked by comparing the timestamp values ​​from the two sources, then calculating the difference between the decrypted timestamp and the current time in the cloud, and determining whether it is within a ±3-second security window. Key correctness is checked by verifying the validity of the encrypted signature of the data packet to ensure that the data has not been tampered with.

[0054] For example, suppose that in a test, responses under different attack scenarios were recorded. Scenario 1: Attacker plays the audio-visual signal recorded at 14:00:05. The session identifier consistency check passes, both are 0x5A3F; the timestamp validity consistency check passes, both are 1717824001000, but the timeliness check fails: the current time on the cloud is 1717824005000, the time difference ΔT = 4000 milliseconds > 3000 milliseconds tolerance; the key correctness check passes. The timestamp validity check fails, and the verification result is output as "failed" within 120ms because the timestamp timed out. Scenario 2: Attacker intercepts the real ultrasonic signal and uses a fake LED light signal to illuminate the access control system. The session identifier decrypted from the audio-visual sensing signal is 0xA1B2, and the session identifier decoded from the video light signal is 0xC3D4. 0xA1B2 is not equal to 0xC3D4, so the session identifier consistency check fails. The session identifier consistency check failed, and the verification result was "not passed" because the session identifiers were inconsistent. In Scenario 3, all data came from a single legitimate request from a valid access control terminal. The identifier was 0xE5F6, the timestamp was 1717824010000, and the cloud reception time was 1717824010200. All three checks passed, and ΔT = 200 milliseconds < 3000 milliseconds. The verification result was output as "passed" within 150ms.

[0055] When the session identifier consistency, timestamp validity, and key correctness are all verified, the video is confirmed to be authentic and valid, and the cloud-based anti-counterfeiting verification result is passed. If any one verification fails, the cloud-based anti-counterfeiting verification result fails. By introducing three independent verification factors—identifier, timestamp, and key—a multi-layered security defense is established. Attackers must breach all defenses simultaneously, significantly increasing the complexity and cost of attacks. The combination of dynamic session credentials and a strict time window ensures that each authentication event is unique and immediate, fundamentally preventing credential reuse, ensuring the authenticity of the smart access control video, and guaranteeing the security and reliability of users remotely viewing the video.

[0056] If the cloud-based anti-counterfeiting verification result is successful, the access control video signal is marked according to the sound and light sensing signal, and the processed access control video signal is sent to the user terminal for display through the relay gateway.

[0057] Furthermore, this application also includes the following steps: setting a watermark processing method, processing the audio-visual sensing signal according to the watermark processing method, and outputting a digital watermark; fusing the access control video signal according to the digital watermark to obtain a watermark-processed access control video signal.

[0058] Furthermore, this application also includes the following steps: generating authentication metadata, processing the watermarked access control video signal according to the authentication metadata, and sending the processed access control video signal to the user terminal; after the user verifies the authentication metadata through the user terminal, the watermarked access control video signal is displayed.

[0059] Specifically, once the cloud-based anti-counterfeiting verification is successful, the access control video signal needs to be labeled. The watermark labeling processing method specifies how to extract features from the audio-visual sensing signals and convert them into a digital watermark signal suitable for embedding in the video, while also defining the watermark's hiding position and strength within the video data.

[0060] Following the watermarking process, the audio-visual sensing signal is processed to extract the session identifier and timestamp, calculate a hash value, and use this as the core information. This hash value is then modulated using spread spectrum technology to generate a digital watermark signal. The digital watermark is a hidden digital code generated from the audio-visual sensing signal using a specific algorithm.

[0061] Digital watermarks are embedded into the original access control video signal, and each frame of the video signal is processed. Watermark embedding methods can employ DCT transform embedding or temporal fine-tuning embedding, embedding anti-counterfeiting information into the luminance or chrominance components. During processing, video quality is maintained, ensuring that the PSNR of the embedded watermark is >40dB, meaning that the human eye can hardly perceive any loss in image quality, meeting professional broadcast requirements. An SSIM >0.98 indicates that the video structural information is preserved almost perfectly, making it virtually imperceptible to the user. For example, the video processing engine uses a DWT-SVD hybrid algorithm to embed the digital watermark into the luminance component of the access control video, performs a 3-level decomposition using Haar wavelets, and embeds the watermark information into the intermediate frequency coefficients of the HL3 and LH3 subbands with an embedding intensity factor of 0.05, ensuring both invisibility and anti-attack capabilities. Calculate the SHA-256 hash value of the watermarked video, such as 8f3c7a...e294, and use the RSA-2048 private key in the cloud to digitally sign the hash value, generating 256 bytes of signature data.

[0062] Authentication metadata is a structured verification data packet used to verify the authenticity of a video. It contains key authentication information such as video hash values, digital signatures, timestamps, and watermark parameters, encapsulated in JSON / XML format and possessing full parsability. The watermarked access control video signal and authentication metadata are packaged together and sent to the user terminal through a relay gateway. Upon receiving this data, the user terminal verifies the authenticity of the authentication metadata and then checks whether the watermark information in the video matches the metadata. Only after passing all these verification steps will the application display the final access control video signal to the user. User terminal verification ensures that the video has not been tampered with during transmission, that the video source is authentic and reliable, and that the video content completely matches the access control event. For example, the original video is 1080p / 30fps, meaning a resolution of 1920×1080 pixels, a frame rate of 30 frames per second (30 still images played per second to form a dynamic video), a duration of 5 seconds, and a watermark data of a 256-bit hash value. The attack method is video recoding, H.264→H.265 transcoding. A video file containing a watermark, approximately 8.3MB in size, was generated in the cloud. A transcoding attack was performed on the video, using H.265 encoding, CRF=28, and scaling the resolution to 720p. After transcoding, the file size decreased to 4.1MB, with a PSNR of 38.7dB. The watermark information was extracted from the transcoded video. The watermark extraction success rate was 98.4%, the authentication metadata verification pass rate was 100%, the video hash verification time was <150ms, and the digital signature verification time was <80ms. While the original video hash and the transcoded video hash changed, the extracted watermark hash remained unchanged; therefore, the metadata verification status was successful.

[0063] With the dual protection of watermark fusion and metadata authentication, the integrity of video content from the cloud to the user terminal is ensured, achieving full coverage of security protection in the transmission link. Attackers cannot tamper with video content at any stage without being detected.

[0064] Furthermore, this application also includes the following steps: determining whether the user terminal is in a preset communication area; if the user terminal is not in the preset communication area, sending the processed access control video signal to the IoT terminal for display through the relay gateway.

[0065] Specifically, after the cloud server completes the anti-counterfeiting verification and watermarking processing of the access control video signal, it does not immediately send the video. Instead, it first initiates the terminal location determination process. Multiple technical means are used to comprehensively determine the user terminal's current location. The system checks the network connection information most recently reported by the user's mobile application. If it shows a connection to the preset home Wi-Fi and the IP address is correct, the user is determined to be at home. Simultaneously, Bluetooth beacon detection is used. If a Bluetooth signal emitted by the living room relay gateway is detected and its strength is greater than -70dBm, it further confirms that the user is within the preset communication area. Once the user terminal confirms that the user is within the preset area, the processed access control video signal is pushed to the user terminal for display.

[0066] If the user terminal is determined to be outside the preset communication area, a backup display mechanism is activated. The relay gateway scans the online IoT terminal devices in the current network and selects the most suitable display device according to a preset priority order. For example, it prioritizes the smart control screen in the living room; if that device is offline, it tries the smart TV in the bedroom, the speaker with a screen in the kitchen, and so on. After selecting the IoT terminal, the relay gateway converts the access control video signal into a format suitable for that device's display. For example, for a smart TV, it converts it to a 1080P HDMI signal; for a smart control screen, it converts it to a video stream adapted to its resolution. Simultaneously, a notification is sent to the user via a mobile application, informing them which device the video is being displayed on, allowing the user to remotely control the IoT terminal's playback via their mobile phone. IoT terminals are devices that can replace user terminals for displaying video, such as indoor smart video intercoms, smart displays in hallways, and property monitoring screens. This ensures that even when the user cannot view the video immediately, the site can still view and respond instantly, achieving redundancy and availability of the access control system.

[0067] The system automatically selects the optimal video display method based on the user's actual location, ensuring that important access control information is delivered in a timely manner. No matter where the user is, they will not miss any important developments at the door. It intelligently coordinates various IoT display devices to form a mutually redundant display network, improving the reliability and coverage of the smart access control system.

[0068] In summary, the smart access control communication method using StarSignal relay gateway collaboration provided in this application has the following technical effects: An audio-visual anti-counterfeiting sensing module is installed in the access control module. The access control module and the audio-visual anti-counterfeiting sensing module are communicatively connected to at least one relay gateway. When a visitor enters the access control identification area, the access control video signal of the access control module is collected, and the audio-visual anti-counterfeiting sensing module is triggered to obtain audio-visual sensing signals, which include flashing light signals and ultrasonic signals. The access control video signal and the audio-visual sensing signals are transmitted to a cloud server through the relay gateway. The cloud server performs cloud anti-counterfeiting verification on the access control video signal based on the audio-visual sensing signals and outputs the cloud anti-counterfeiting verification result. If the cloud anti-counterfeiting verification result is successful, the access control video signal is marked according to the audio-visual sensing signals, and the processed access control video signal is sent to the user terminal for display through the relay gateway. In other words, by using a StarFlash relay gateway to achieve ultra-low power connection and adding an audio-visual anti-counterfeiting sensing module, the high-frequency flashing light signal is uploaded to the cloud server as evidence to verify whether the video is real. After verification, the video is pushed to the user, thus realizing verifiable video authenticity and long-lasting door lock battery life, thereby improving the security of smart access control.
