Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0021] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure.

[0022] It should be noted that the user information involved in this disclosure includes, but is not limited to, user device information and user personal information; the collection, storage, use, processing, transmission, provision and disclosure of user information in this disclosure all comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0023] To address the aforementioned technical issues, some embodiments of this disclosure involve obtaining a privacy-triggered terminal's silent encryption command. The privacy-triggered terminal and the compatible controlled terminal integrate a privacy handshake protocol. In response to a privacy protection activation operation, the privacy-triggered terminal sends a silent encryption command to surrounding devices according to a preset period based on the privacy handshake protocol. The command is then validated for legality, and a validation result is obtained. If the validation result is successful, the image acquisition function of the compatible controlled terminal is disabled. Based on a privacy-triggered terminal and a compatible controlled terminal integrated with a privacy handshake protocol, this disclosure allows the privacy-triggered terminal to control the compatible controlled terminal and disable its image acquisition function by sending a silent encryption command when privacy protection is required. This protects personal information from leakage, improves personal information security, and enhances user experience.

[0024] The technical solutions provided by the embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic flowchart of a device control system 10 provided for an exemplary embodiment of this disclosure. Figure 1 As shown, the device control system 10 includes a privacy trigger terminal 11 and at least one compatible controlled terminal 12. The at least one compatible controlled terminal is located within the effective communication range of the privacy trigger terminal; the privacy trigger terminal and the compatible controlled terminal integrate a privacy handshake protocol.

[0026] The privacy-triggered terminal 11, in response to the privacy protection activation operation, generates a privacy silent encryption command according to the privacy handshake protocol; and sends the privacy silent encryption command to the surrounding area according to a preset period. The compatible controlled terminal 12, after listening to the privacy silent encryption command issued by the privacy trigger terminal, performs a legality verification on the privacy silent encryption command and obtains the verification result; if the verification result is successful, the image acquisition function of the compatible controlled terminal is turned off.

[0027] In this embodiment, the implementation form of the privacy trigger terminal 11 is not limited. The privacy trigger terminal can be any one of a portable trigger, a software switch for a smart device, or a physical button for a smart wearable device. The privacy trigger terminal has a built-in Bluetooth communication module and a control processing unit, and is equipped with a physical or software privacy enable switch; after the switch is activated, it periodically broadcasts Bluetooth privacy silence signals according to a preset specification, limiting the effective short-range coverage area, which can only be received and identified by nearby devices.

[0028] It should be noted that privacy-triggered terminals and compatible controlled terminals use existing communication modules, requiring only the embedding of standardized protocol firmware. No new chips or hardware modifications are needed, resulting in lower costs.

[0029] Portable triggers, such as portable keychains and portable cards, feature a built-in BLE chip that enables broadcasting functionality. The privacy protection function is activated by pressing a button on the portable trigger; alternatively, the portable trigger can be set to a always-on privacy protection mode.

[0030] In this embodiment, smart devices include, but are not limited to: smartphones, tablets, laptops, home smart cameras, office smart screens, and other electronic products with Bluetooth and camera functions.

[0031] A software switch for a smart device can be a system-level virtual control integrated into the smart device, or a virtual control set within an application installed on the smart device. The smart device responds to the triggering of the software switch by enabling privacy protection features.

[0032] Physical buttons on smart wearable devices can be physical mechanical buttons, micro switches, or slide switches integrated into the device's casing. In response to triggering operations on these physical buttons (such as pressing, holding, or flicking), the smart wearable device activates hardware-level or system-level privacy protection functions.

[0033] In this embodiment, the compatible controlled terminal 12 is not limited to any particular type. The compatible controlled terminal 12 includes: novel AI wearable devices and traditional smart terminals. Novel AI wearable devices include, but are not limited to: AI glasses, AI camera headsets, AI neck pendants, and AI smartwatches; traditional smart terminals include, but are not limited to: smartphones, tablets, laptops, home smart cameras, and office smart screens. Each compatible controlled terminal has a background resident command monitoring process that continuously monitors the broadcast channel specified by the protocol. Upon receiving a valid, encrypted privacy-silencing command, it automatically shuts down the camera, disables photo and video recording, and locks camera access. When it leaves the signaling coverage area and no valid signaling is detected for a preset duration, it automatically unsilences the camera and restores normal shooting functionality.

[0034] In this embodiment, the privacy handshake protocol is a general embedded protocol that uniformly specifies the signaling frame format, broadcast channel, encryption verification, and device silent recovery logic. Specifically, the privacy handshake protocol is a defined industry-standard protocol that uniformly specifies the signaling frame format, broadcast channel, encryption verification rules, authentication logic, silent duration, and offline recovery rules. The privacy handshake protocol is compatible with traditional Bluetooth and BLE Low Energy Bluetooth, and can be embedded in the firmware or system layer of all electronic products with Bluetooth and cameras, such as AI glasses, AI headphones, AI neckbands, AI watches, mobile phones, tablets, and smart cameras. The privacy handshake protocol can be a Bluetooth standardized handshake protocol, an out-of-band handshake protocol, an elliptic curve-based key exchange handshake protocol, or a Bluetooth Mesh dedicated beacon protocol. The privacy silent encryption command includes a protocol version field, a device identifier field, an encryption key field, and a checksum field. The privacy handshake protocol defines a dedicated broadcast advertising frame and uses a symmetric encryption algorithm to prevent malicious forgery of signaling to arbitrarily shut down other people's devices. It is compatible with controlled terminals by embedding a protocol listening module in the system firmware and underlying driver, without relying on third-party applications; the device can be pre-installed with the adaptation at the factory.

[0035] In this embodiment, a privacy-triggered terminal sends a privacy-silent encryption command. The privacy-triggered terminal and the compatible controlled terminal integrate a privacy handshake protocol. In response to a privacy protection activation operation, the privacy-triggered terminal sends a privacy-silent encryption command to surrounding devices according to a preset cycle based on the privacy handshake protocol. The privacy-silent encryption command is validated for legality, and a validation result is obtained. If the validation result is successful, the image acquisition function of the compatible controlled terminal is disabled. This disclosure is based on a privacy-triggered terminal and a compatible controlled terminal integrated with a privacy handshake protocol. When privacy protection is required, the privacy-triggered terminal can control the compatible controlled terminal by sending a privacy-silent encryption command, disabling its image acquisition function, protecting personal information from leakage, improving personal information security, and enhancing user experience. Utilizing the common hardware foundation of communication modules standard in various electronic devices, a unified privacy signaling rule is established. This enables all compatible AI wearable devices and smart terminals in the vicinity to automatically disable their image acquisition functions after a user activates privacy protection with one click, thereby improving personal information security.

[0036] It should be noted that the effective communication distance refers to the maximum spatial distance that a signal or data can be effectively transmitted from the transmitting end to the receiving end in a communication system, provided that certain quality indicators are guaranteed (such as meeting specific bit error rate, signal-to-noise ratio, packet loss rate, or received signal strength). In this embodiment, the effective communication distance can be limited to a commonly used indoor social distance through Bluetooth transmit power calibration, and will automatically fail if the range is exceeded.

[0037] In some embodiments of this disclosure, the privacy-triggered terminal, in response to a privacy protection enable operation, generates a privacy-silent encryption command according to a privacy handshake protocol and sends the privacy-silent encryption command to its surroundings at a preset period. The privacy-triggered terminal includes a privacy protection enable switch and a communication module. In a privacy protection scenario, after the privacy protection is enabled by the user's privacy-protection enable operation, the privacy-triggered terminal sends the privacy-silent encryption command to its surroundings at a preset period. It should be noted that this disclosure does not limit the preset period; it can be 5 seconds, 10 seconds, etc.

[0038] In some embodiments of this disclosure, after a compatible controlled terminal receives a privacy-triggered silent encryption command from a privacy-triggered terminal, it performs a validity check on the command and obtains a verification result. Specifically, at least one compatible controlled terminal near the privacy-triggered terminal continuously listens to designated broadcast information. Upon receiving a privacy-triggered silent encryption command from the privacy-triggered terminal, it performs protocol matching, key decryption, and data validity verification on the command, obtaining a verification result.

[0039] Specifically, the compatible controlled terminal first parses the packet header to verify whether it contains the expected privacy encryption protocol identifier. If a match is found, the decryption process begins; otherwise, the packet is discarded or an error is returned to prevent the misprocessing of illegal data. The compatible controlled terminal extracts the symmetric session key (such as an AES key) protected by asymmetric encryption (such as RSA / ECC) from the packet and decrypts it using a locally stored private key, thus securely restoring the plaintext key used to decrypt the command content. Using the restored symmetric key and the accompanying authentication tag (such as AES-GCM mode), the compatible controlled terminal verifies the integrity and origin of the ciphertext, while also checking the timestamp and nonce to prevent replay attacks, ensuring that the data has not been tampered with during transmission and originates from a legitimate sender. The compatible controlled terminal outputs a final judgment based on the execution status of the above steps. If all verification steps pass, a successful verification result is generated; if any verification step fails, a failed verification result is generated.

[0040] If the verification passes, disable the image acquisition function of the compatible controlled terminal. This involves locking camera access permissions at both the hardware power supply layer and the system driver layer, and preventing background applications from waking up the image acquisition function. For example, the compatible controlled terminal will automatically turn off the camera and disable image acquisition functions such as taking photos and recording videos.

[0041] In one alternative embodiment, when the privacy handshake protocol is the Bluetooth standard handshake protocol, the Bluetooth standard handshake protocol is compatible with Bluetooth Low Energy 4.0 and above, reusing the device's original Bluetooth hardware module without the need for additional hardware chips.

[0042] In one optional embodiment, the privacy-silent encryption command includes a protocol version field, a device identifier field, an encryption key field, and a verification code field. Only compatible controlled terminals that pass the full verification process execute the camera shutdown action, preventing malicious forgery of commands. The privacy-silent encryption command can be broadcast signaling over a standard Bluetooth channel, without interfering with public radio frequencies, and can be promoted as an industry standard and included in the pre-installed protocol of devices.

[0043] When the compatible controlled terminal moves away from the effective communication distance of the privacy triggering terminal, and no privacy-silencing encryption command is detected within a preset time period, the image acquisition function of the compatible controlled terminal is activated. It should be noted that this disclosure automatically deactivates the image acquisition function and restores normal operation when the compatible controlled terminal moves away from the effective communication distance of the privacy triggering terminal and no privacy-silencing encryption command is detected within a preset time period. It activates at close range and automatically recovers at long range, eliminating the need for manual operation of peripheral devices individually, making it convenient for social, business, and office scenarios.

[0044] In addition to providing the aforementioned equipment control system 10, this disclosure also provides an equipment control method. It should be noted that the equipment control method provided in this disclosure can depend on the aforementioned equipment control system 10, or it can operate independently of the equipment control system 10.

[0045] Figure 2 This is a schematic flowchart illustrating a device control method provided for an exemplary embodiment of this disclosure. Figure 2 As shown, the device control method includes: S201: Obtain the privacy silent encryption command issued by the privacy trigger terminal; wherein, the privacy trigger terminal and the compatible controlled terminal are integrated with a privacy handshake protocol, and the privacy trigger terminal responds to the privacy protection enable operation and issues the privacy silent encryption command to the surrounding area according to the privacy handshake protocol and a preset period. S202: Perform a legality check on the privacy silent encryption command and obtain the check result; S203: If the verification result is successful, disable the image acquisition function of the compatible controlled terminal.

[0046] In this embodiment, the disclosure does not limit the compatible controlled terminals, which include: novel AI wearable devices and traditional smart terminals. Novel AI wearable devices include, but are not limited to: AI glasses, AI camera headsets, AI neck pendants, and AI smartwatches; traditional smart terminals include, but are not limited to: smartphones, tablets, laptops, home smart cameras, and office smart screens. Each compatible controlled terminal has a background resident command listening process that continuously listens to the broadcast channel specified by the protocol; upon receiving a valid and encrypted privacy silent command, it automatically executes actions such as turning off the camera, disabling photo and video recording, and locking camera access; when it leaves the signaling coverage area and no valid signaling is detected for a preset period of time, it automatically unsilences the camera and restores normal shooting function.
